Disclosure of Invention

Problems to be solved by the invention

In the conventional vehicle seat described above, the planar member may move (so-called lateral sliding may occur) in a direction along the edge portion along the passing portion of the attachment line. An object of the present invention is to suppress a planar member of a planar support from moving in a direction along an edge portion thereof.

Means for solving the problems

[1] In a first aspect of the present invention, a vehicle seat includes a seat frame and a planar support body that is attachable to the seat frame,

the planar support comprises:

a flexible planar member that receives an external force from the seat surface;

a mounting wire which holds an edge portion of the planar member and is mounted to the seat frame; and

a clamp disposed between the mounting line and the seat frame,

the intermediate member has a regulating portion that engages with the planar member to regulate the planar member from moving in an edge direction along the edge portion.

According to the first aspect, the movement of the planar member in the edge direction along the edge portion is regulated by the regulating portion provided in the interposed member. This suppresses the movement of the planar member of the planar support body in the edge direction.

[2] In a second aspect of the invention, according to the first aspect described above,

the regulating portion has an abutting wall that abuts against the planar member in the edge direction to suppress the planar member from moving in the edge direction.

According to the second aspect, the function of the regulating portion can be realized by the contact wall of a simple structure that contacts the planar member from the edge direction.

[3] In a third aspect of the present invention, according to the second aspect described above,

the planar member has a cutout portion provided at a middle portion of the edge portion, the cutout portion being provided so that the edge portion is recessed in a direction intersecting the edge direction,

the abutting wall abuts against the inner periphery of the notch part in the edge direction.

According to the third aspect, the contact wall of the regulating portion is brought into contact with the inner peripheral edge of the cutout portion provided in the middle of the edge portion of the planar member, whereby the movement of the planar member in the edge direction can be appropriately suppressed. Thus, the size of the interposed member in the edge direction can be reduced as compared with a case where the abutting wall is disposed outside the edge portion so as to sandwich the planar member in the edge direction.

[4] In a fourth aspect of the present invention, according to the third aspect described above,

the mounting wire has a mounting portion extending from the edge portion of the planar member toward the seat frame,

the intermediate member has a mounted portion that holds the mounting portion, and the mounted portion is configured such that a part of the mounted portion abuts against the inner peripheral edge of the cutout portion in the edge direction as the abutting wall.

According to the fourth aspect, the attached portion having the function of holding the attachment portion extending from the attachment wire toward the seat frame also has the function of abutting against the inner peripheral edge of the cutout portion of the planar member to suppress the movement of the planar member. With such a rational structure, the sheet-like member can be prevented from moving in the edge direction while avoiding an increase in size of the interposed member as much as possible.

However, when the planar member is provided with "a plurality of" mounting wires, it is relatively complicated to mount the mounting wires while appropriately positioning the mounting wires at predetermined positions of the seat frame, and it is difficult to improve the operability. In this regard, another object of the present invention is to facilitate the assembly of the planar support to the seat frame.

[5] In a fifth aspect of the present invention, a vehicle seat includes a seat frame and a planar support body that is attachable to the seat frame,

the planar support comprises:

a flexible planar member that receives an external force from the seat surface;

a plurality of attachment wires that hold an edge portion of the planar member and are attached to the seat frame; and

a clamp disposed between the mounting line and the seat frame,

the plurality of mounting wires are arranged along the edge portion, each of the plurality of mounting wires having a mounting portion extending from the edge portion toward the seat frame,

the intermediate member has a plurality of attached portions that hold the plurality of attachment portions extending from the plurality of attachment lines at predetermined holding positions so as to be aligned in an edge direction along the edge portion.

According to the fifth aspect, when a plurality of mounting wires are provided at the edge portion of the planar member, the mounting wires can be collectively held by the intermediate member, and the intermediate member can be mounted on the seat frame. This allows the plurality of mounting wires to be easily mounted while being appropriately positioned at a predetermined position of the seat frame.

[6] In a sixth aspect of the present invention, according to the fifth aspect described above,

further comprises a seat cushion disposed in contact with the planar member,

the clip has a cushion support surface portion that supports the seat cushion.

According to the sixth aspect, the cushion support surface portion provided in the intermediate member can prevent the escape of the seat cushion when a load of a seated person is applied, and the riding comfort can be improved more appropriately than the case where the cushion support surface portion is provided as a member different from the intermediate member.

[7] In a seventh aspect of the present invention, according to the fifth aspect described above,

further comprises a seat cover arranged to cover the vehicle seat,

the insert member has a fixed attachment portion to which the seat cover is fixedly attached.

According to the seventh aspect, the seat cover is fixed and attached by the fixing and attaching portion provided in the intermediate member, whereby the seat cover can be reasonably fixed as compared with a case where the fixing and attaching portion is provided as a member different from the intermediate member.

[8] In an eighth aspect of the present invention, according to any one of the fifth to seventh aspects described above,

the planar support comprises:

a first interposed member provided corresponding to a first edge of the planar member;

a second interposed member provided corresponding to a second edge of the planar member; and

an erection portion connecting the first and second clamping members.

According to the eighth aspect described above, the plurality of mounting wires are positioned with respect to the seat frame by one of the first and second intermediate members, and thus the plurality of mounting wires are also positioned with respect to the seat frame by the other intermediate member connected to the one intermediate member. Therefore, the plurality of mounting wires can be more easily mounted to the seat frame.

However, in the case where the "seat cushion" is provided so as to abut against the planar member, when the seat cushion receives a load from a seated person, the seat cushion is displaced so as to be pushed out through a gap between the planar member and the seat frame, and the sitting comfort of the vehicle seat may be impaired. Yet another object of the present invention is to suppress displacement of such a seat cushion.

[9] In a ninth aspect of the present invention, a vehicle seat includes a seat frame, a planar support body attachable to the seat frame, and a seat pad supported by the planar support body, the planar support body including:

a flexible planar member that receives an external force from the seat cushion;

a clamp disposed between the mounting line and the seat frame,

the mounting wire extends from the edge portion of the planar member toward the seat frame,

the insert member has a cushion support surface portion that supports the seat cushion at a gap between the planar member and the seat frame.

According to the ninth aspect of the present invention, the cushion support surface portion provided in the intermediate member can suppress displacement of the seat cushion so as to be pushed out through the gap between the planar member and the seat frame.

[10] In a tenth aspect of the present invention, according to the ninth aspect described above,

the mounting wire has a pair of mounting portions extending toward the seat frame,

the cushion support surface portion supports the seat cushion between the pair of mounting portions.

According to the tenth aspect of the present invention, the pad support surface portion can appropriately fill the gap formed between the pair of attachment portions of the attachment wire, thereby appropriately suppressing displacement of the seat pad.

[11] In an eleventh aspect of the present invention, according to the tenth aspect described above,

the pair of the mounting portions each have: a straight portion extending linearly toward the seat frame; and a bent portion bent in a hook shape from an extended end of the linear portion,

the pad support surface portion is provided so as to block a space between the pair of linear portions.

According to the eleventh aspect described above, the cushion support surface portion is provided so as to close between the pair of straight portions of the attachment line, whereby the seat cushion is more appropriately received by the cushion support surface portion.

However, when a "fixing portion" such as a jig for fixing peripheral members such as a wire harness is provided on the planar support body, the riding comfort of the vehicle seat may be impaired due to such a foreign body sensation caused by the jig or the like. Still another object of the present invention is to provide a fixing portion so that the riding comfort of a vehicle seat is not easily impaired.

[12] In a twelfth aspect of the present invention, a vehicle seat includes a seat frame and a planar support body that can be attached to the seat frame,

the planar support comprises:

a flexible planar member that receives an external force from the seat surface;

a clamp disposed between the mounting line and the seat frame,

the intermediate member has a fixing portion capable of fixing a predetermined peripheral member in a region of a back surface side of the planar member opposite to a front surface side facing the seat surface.

According to the twelfth aspect, since the fixing portion capable of fixing the peripheral member is provided in the region on the back surface side of the planar member, the fixing portion is not exposed on the front surface side of the planar member. Therefore, the fixing portion can be attached to the planar support body so as to be less likely to impair the riding comfort of the vehicle seat.

[13] In a thirteenth aspect of the invention, according to the twelfth aspect described above,

the fixing portion is disposed apart from a rear surface of the planar member.

According to the thirteenth aspect described above, even if the planar member deflects toward the rear surface side upon receiving a load from the seat surface, it is difficult to interfere with the fixed portion. Therefore, the peripheral member can be attached to the planar support body so as to be more unlikely to impair the riding comfort of the vehicle seat.

[14] In a fourteenth aspect of the present invention, according to the twelfth or thirteenth aspect described above,

the planar support comprises:

an erection unit connecting the first and second sandwiching members,

the mounting portion has the fixing portion.

According to the fourteenth aspect of the present invention, the bridge portion connecting the first and second intermediate members supports both ends of the intermediate members, and therefore, the structural strength is high. Therefore, by providing the fixing portion in such a bridge portion, the peripheral member can be more firmly fixed.

Effects of the invention

The vehicle seat of the present invention can suppress the planar member of the planar support body from moving in a direction along the edge portion thereof.

Detailed Description

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

Example 1

General Structure of seat 1

First, the structure of a seat 1 (vehicle seat) according to embodiment 1 will be described with reference to fig. 1 to 9. In the following description, the terms "front, rear, up, down, left, right, and the like" refer to the respective directions shown in the respective drawings. In addition, the term "seat width direction" refers to the left-right direction of the seat 1.

As shown in fig. 1, a seat 1 of the present embodiment is configured as a seat of an automobile, and includes a seat back 2 serving as a backrest of a seated person and a seat cushion 3 serving as a seating portion. Lower end portions on both left and right sides of the seat back 2 are connected to rear end portions on both left and right sides of the seat cushion 3 via a reclining adjuster, not shown, in a state in which the backrest angle can be adjusted. The seat cushion 3 is coupled to a floor of the vehicle in a state in which a position in the front-rear direction can be adjusted between the pair of left and right slide rails 4 via the pair of left and right slide rails 4.

The seat cushion 3 is substantially composed of a metal cushion frame 3F assembled into a substantially frame shape in plan view, a cushion pad 3P made of foamed polyurethane provided above the cushion frame 3F to elastically receive the load of the seated person, and a cushion cover 3C made of fabric covering the entire surface of the cushion pad 3P to form the outer appearance of the seat cushion 3. A planar support 10 capable of supporting the central region of the cushion pad 3P in a planar manner over a wide range from the lower side is mounted between the front and rear frame portions of the cushion frame 3F. Here, the cushion frame 3F corresponds to a "seat frame" of the present invention, the cushion pad 3P corresponds to a "seat cushion" of the present invention, and the cushion cover 3C corresponds to a "seat cover" of the present invention.

Structure of cushion frame 3F

As shown in fig. 2, the cushion frame 3F is formed by assembling a pair of left and right side frames 3Fa, a front plate 3Fb integrally provided between the front ends of the side frames 3Fa, a front pipe 3Fc integrally provided between the side frames 3Fa at a position rearward and below the front plate 3Fb, and a rear pipe 3Fd integrally provided between the rear ends of the side frames 3Fa into a substantially frame-like shape in plan view.

The pair of left and right side frames 3Fa described above are each formed of a vertical plate-like frame member extending in a long-length manner in the front-rear direction, and form left and right side frames of the seat cushion 3. The front plate 3Fb is formed of a plate-shaped frame member facing the surface in the height direction, and forms a front frame of the seat cushion 3. The front tube 3Fc and the rear tube 3Fd are each formed of a circular tube member extending linearly in the seat width direction (i.e., the edge direction), and each side frame 3Fa is inserted so as to penetrate therethrough and firmly integrated with the side frame 3 Fa.

By the above-described connection, the cushion frame 3F is assembled into a substantially frame-like shape in plan view, and the outer peripheral portion of the cushion pad 3P provided on the upper portion thereof can be strongly supported from below. The leg portions 3Fe that raise the slide rails 4 on each side are welded to both ends of the front pipe 3Fc and the rear pipe 3 Fd.

Structure of cushion pad 3P

Referring to fig. 1, the cushion pad 3P is placed in a state of covering the above-described cushion frame 3F from above. More specifically, the cushion pad 3P covers the cushion frame 3F from above, and the front, rear, left, and right peripheral edge portions thereof are respectively set in a state of being turned around downward by passing through the outer peripheral side of the cushion frame 3F. By the above-described assembly, the cushion pad 3P is provided in a state in which the outer peripheral portion is strongly supported from below by the above-described not-shown cushion frame 3F, and the central portion is elastically supported from below by the planar support body 10 erected in the frame of the cushion frame 3F in a planar manner.

Structure of cushion cover 3C

The cushion cover 3C covers the cushion pad 3P from above, and is integrally fixed to the cushion frame 3F by pulling in the respective front, rear, left, and right peripheral edge portions thereof downward through the outer peripheral side of the cushion pad 3P. By the above-described assembly, the cushion cover 3C is stretched and brought into close contact with the entire surface of the cushion pad 3P over a wide range, and the cushion pad 3P is held in a fixed position by being pressed against the cushion frame 3F.

Structure of planar support 10

As shown in fig. 1, 5, and 8, the planar support 10 includes: a planar member 11 made of a fabric cut out to have a substantially rectangular shape in a plan view; front and rear

metal attachment lines

12A and 12B for attaching front and rear edges of the planar member 11 to the front and rear tubes 3Fc and 3Fd, respectively; and a resin structure 13 fitted over the mounting

wires

12A and 12B and interposed between the front mounting wire 12A and the front tube 3Fc and between the rear mounting wire 12B and the rear tube 3Fd, respectively.

Structure of planar Member 11

The planar member 11 is formed of a woven fabric (or a knitted fabric) having a substantially uniform structure, in which the weft is formed of a PET resin having low stretchability and the warp is formed of a PTT resin having higher stretchability than the weft. In the planar member 11,

passage openings

11A and 11B are formed along the front and rear edges of the planar member, the passage openings being formed by folding back the edges toward the back side and sewing the edges into a tubular shape. As shown in fig. 3 to 5, the

passage openings

11A and 11B are formed substantially over the entire region in the seat width direction of the edge portion on each side of the planar member 11. However, the above-described

passage ports

11A and 11B are configured such that the openings 11Aa and 11Ba formed by cutting out the folded portions formed at the central portions of the edge portions on the respective sides of the planar member 11 into substantially rectangular openings are formed such that the folded portions at the central portions are opened to the outside. In other words, cut portions (i.e., openings 11Aa and 11Ba) are provided at intermediate positions of the edge portion of the planar member 11 so that the edge portion is recessed in a direction intersecting a direction along the edge portion (the same as the "seat width direction" described above, and hereinafter also referred to as "edge direction"). As shown in fig. 9, the planar member 11 receives an external force from a seat surface (a surface of the seat cushion 3 on the side of the seated person) when the seated person sits on the seat 1 or the like.

Structure of mounting

lines

12A and 12B

The front and

rear mounting lines

12A, 12B are formed as a pair of left and right, and are provided so as to pass through the

respective passage openings

11A, 11B formed in the edge portions on the respective sides of the planar member 11 in a lateral arrangement. Specifically, the front pair of mounting wires 12A are each formed of a wire rod bent into a substantially U shape in plan view, having a passage portion 12Aa and a pair of left and right hook portions 12Ab, wherein the passage portion 12Aa passes through a left and right cylindrical opening partitioned by a central opening portion 11Aa of the passage opening 11A formed in the front edge portion of the planar member 11, and the pair of left and right hook portions 12Ab are formed so as to extend from respective ends of front ends of the passage portions 12Aa protruding from the respective cylindrical openings, bent linearly forward and upward, and bent convexly and downward. Here, each hook portion 12Ab corresponds to the "attachment portion" of the present invention. As will be described in detail later, the attachment wire 12A is attached to the cushion frame 3F while holding the edge of the planar member 11. The hook portion 12Ab extends from the edge of the planar member 11 toward the cushion frame 3F. The same applies to the later-described mounting line 12B.

Similarly, the rear pair of mounting wires 12B are each formed of a wire rod bent in a substantially U shape in plan view, the wire rod having a passing portion 12Ba and a pair of left and right hook portions 12Bb, the passing portion 12Ba passing through a cylindrical opening on each of the left and right sides partitioned by a central opening portion 11Ba of a passage opening 11B formed in the rear edge portion of the planar member 11, and the pair of left and right hook portions 12Bb extending from each end of the front end of the passing portion 12Ba protruding from each cylindrical opening in a linearly bent manner toward the rear upper side and bent in a convexly curved manner toward the lower side. Here, each hook portion 12Bb corresponds to the "attachment portion" of the present invention.

As shown in fig. 3 to 4, in a state where the front and

rear mounting lines

12A and 12B are assembled by passing the passing portions 12Aa and 12Ba through the respective

side passing openings

11A and 11B of the planar member 11, first, as shown in fig. 2, the hook portions 12Ab and 12Bb are fitted into the front and

rear collars

13A and 13B of the resin structure 13, respectively, which will be described later, and are integrally assembled to the resin structure 13. Here, the front and

rear collars

13A and 13B of the resin structure 13 correspond to "an intermediate member" in the present invention, respectively.

Next, the

collars

13A and 13B of the resin structure 13 fitted with the mounting

wires

12A and 12B are press-fitted into the front tube 3Fc and the rear tube 3Fd, respectively, from above. Thus, the mounting

wires

12A and 12B are mounted to the front tube 3Fc and the rear tube 3Fd via the resin structural body 13 in a state of being fitted from above (see fig. 5 and 8). The order of assembling the resin structure 13 to the front tube 3Fc and the rear tube 3Fd is specifically performed by first fitting a rear collar 13B of the resin structure 13, which will be described later, to the rear tube 3Fd from above, and then fitting a front collar 13A to the front tube 3Fc from above.

The reason for this is as follows. That is, as shown in fig. 5, this is because the rear collar 13B of the resin structure 13 is fitted from above and assembled to the rear pipe 3Fd, and is provided between the projecting portions 3Sa projecting from the resin side protecting portion 3S attached to the side frames 3Fa on each side toward the inside (axial direction) in the seat width direction along the outer peripheral portion of the rear pipe 3Fd, whereby the assembly position in the seat width direction with respect to the rear pipe 3Fd is positioned between the projecting portions 3 Sa.

Therefore, the resin structure 13 can also position the front collar 13A with respect to the seat width direction assembly position of the front tube 3Fc at once by assembling the rear collar 13B to the rear tube 3Fd and then fitting the front collar 13A to the front tube 3Fc from above in a manner of falling down forward with the rear tube 3Fd as the center.

By the above assembly, the mounting

wires

12A and 12B are mounted to the front tube 3Fc and the rear tube 3Fd via the resin structural body 13, and the planar member 11 can be installed in a state of being bridged therebetween. That is, the

collars

13A and 13B are disposed between the

attachment wires

12A and 12B and the cushion frame 3F. As shown in fig. 8, the mounting

lines

12A and 12B can strongly support the load applied to the planar member 11 from the cushion pad 3P provided on the upper portion of the planar member 11 from the front and rear sides by the both-end support structure assembled to the front tube 3Fc and the rear tube 3Fd via the front and

rear collars

13A and 13B of the resin structure 13.

More specifically, as shown in fig. 9, even when a load of a seated person is applied to the seat cushion 3 and the planar member 11 receives a load such as being pushed downward, the above-described

mounting lines

12A and 12B can elastically receive the above-described load while rotating the hook portions 12Ab and 12Bb thereof together with the front and

rear collars

13A and 13B with respect to the front and rear tubes 3Fc and 3 Fd. At this time, since the

resin collars

13A and 13B are interposed between the mounting

wires

12A and 12B and the front tube 3Fc and the rear tube 3Fd, noise caused by friction between metals or the like does not occur between the mounting wires and the front tube 3Fc and the rear tube 3Fd, and the mounting wires can be smoothly rotated or restored to their original positions.

Structure of resin Structure 13

As shown in fig. 1 to 2 and 5, the resin structure 13 is formed as one member by injection molding, which integrally includes a collar 13A on the front side to be fitted to the front tube 3Fc from above by fitting the hook portions 12Ab of the pair of front mounting wires 12A, a collar 13B on the rear side to be fitted to the rear tube 3Fd from above by fitting the hook portions 12Bb of the pair of rear mounting wires 12B, and a bridge portion 13C that integrally connects the front and

rear collars

13A and 13B.

Concerning the front side collar 13A

As shown in fig. 3 to 4, the front collar 13A includes: a pair of laterally arranged attached portions 13Aa to which the left and right hook portions 12Ab of the pair of front attachment wires 12A can be attached so as to be positioned in the seat width direction (i.e., the edge direction) in a pair-by-pair manner; and a connecting portion 13Ab that integrally connects the mounted portions 13Aa to each other. The pair of attached portions 13Aa arranged in the transverse direction described above each have: a pair of engaging portions 13Aa1 bent like a hook and having an extended shape, and capable of being integrally attached by individually elastically click-engaging the left and right hook portions 12Ab of the front pair of mounting wires 12A by individually press-fitting the left and right hook portions 12Ab from above; a connecting surface portion 13Aa2 extending in the seat width direction so as to connect the linearly extending portions of the pair of fitting portions 13Aa1 in series; and upright wall portions 13Aa3 that extend rearward from the respective fitting portions 13Aa1 along the shape of the respective mounting lines 12A fitted to the respective fitting portions 13Aa1, and that contact the respective lateral surfaces of the front edge side of the planar member 11 facing the lateral sides from the outer side or the inner side in the seat width direction (i.e., the edge direction). Here, each standing wall portion 13Aa3 corresponds to a "regulating portion" of the present invention, a portion of each standing wall portion 13Aa3 that contacts the planar member 11 corresponds to a "contact wall" of the present invention, and each connecting surface portion 13Aa2 corresponds to a "pad supporting surface" of the present invention.

The left and right fitting portions 13Aa1 of the pair of laterally arranged attached portions 13Aa are configured to have a substantially U-shaped cross-section fitting groove into which the left and right hook portions 12Ab of the pair of front attachment wires 12A can be fitted so as to be sandwiched from both sides in the seat width direction, and a claw shape that engages by pressing the hook portions 12Ab into the fitting grooves and elastically engages at each portion of the hook portions 12Ab so that the hook portions 12Ab do not come out of the fitting grooves. The above-described fitting portions 13Aa1 are attached to the outer peripheral portion of the front tube 3Fc in a state in which the hook shapes of the fitting portions 13Aa1 are restored after being elastically pressed and deflected by interference with the outer peripheral shape of the front tube 3Fc by press-fitting the front tube 3Fc from above in a state in which the left and right hook portions 12Ab of the front pair of attachment wires 12A are fitted to the fitting portions 13Aa1, as shown in fig. 1 to 2 and 5. With this configuration, the plurality of attached portions 13Aa hold the plurality of hook portions 12Ab extending from the plurality of attachment lines 12A at predetermined holding positions so as to be aligned in the edge direction along the edge portion of the planar member 11. The same applies to the mounted portion 13Ba described later.

As shown in fig. 5 and 8, the connecting surface portions 13Aa2 connecting the fitting portions 13Aa1 in series are formed in such a manner that the gaps Tf formed between the upper surface portions of the front tubes 3Fc to be hooked to the fitting portions 13Aa1 and the edge portions on the front side of the planar member 11 are filled with a flat surface smoothly connecting the planar member 11 and the upper surface portions of the front tubes 3Fc, and the fitting portions 13Aa1 are connected to each other. According to the above configuration, as shown in fig. 8 to 9, each of the connecting surface portions 13Aa2 is in surface contact with the bottom surface portion between the planar member 11 and the front pipe 3Fc of the cushion 3P provided on the upper portion of the planar member 11 from the diagonally front lower side, and the bottom surface portion of the cushion 3P is supported by the surface shape smoothly connecting the planar member 11 and the front pipe 3Fc, whereby the cushion 3P can be pressed so as not to escape from the gap Tf.

As shown in fig. 3 and 5, the vertical wall portion 13Aa3 extending rearward from each of the fitting portions 13Aa1 along the shape of each of the mounting lines 12A is bent in the seat width direction along the shape of each of the mounting lines 12A bent from each of the hook portions 12Ab toward the passing portion 12Aa, and the end portion of the front end extending rearward from the shape of each of the left and right hook portions 12Ab of each of the mounting lines 12A is brought into contact with each of the lateral side surfaces of the front edge side of the planar member 11 from the outer side or the inner side in the seat width direction. Similarly to the fitting portions 13Aa1, the upright wall portions 13Aa3 are formed in a shape having fitting grooves each having a substantially U-shaped cross section, the fitting grooves each having a substantially U-shaped cross section being capable of fitting the mounting wires 12A in a manner of being sandwiched from both sides, and the upright wall portions each sandwiching the passing portions 12Aa of the mounting wires 12A from the front and rear sides are in contact with the side surfaces of the front edge side of the planar member 11 facing the lateral side from the outside or the inside in the seat width direction.

More specifically, among the above-described upright wall portions 13Aa3, the upright wall portion 13Aa3 extending rearward from the right fitting portion 13Aa1 of the right mounted portion 13Aa and the upright wall portion 13Aa3 extending rearward from the left fitting portion 13Aa1 of the left mounted portion 13Aa extend so as to be bent inward in the seat width direction along the shape of the corresponding mounting line 12A, and are in contact with the right outer side surface and the left outer side surface of the planar member 11 from the outer side in the seat width direction. As shown in fig. 6, the upright wall portion 13Aa3 extending rearward from the left fitting portion 13Aa1 of the right mounted portion 13Aa and the upright wall portion 13Aa3 extending rearward from the right fitting portion 13Aa1 of the left mounted portion 13Aa extend so as to be bent outward in the seat width direction along the shape of each corresponding mounting line 12A, and are brought into contact with the right inner surface and the left inner surface of the opening 11Aa formed in the center portion of the front edge side of the planar member 11 from the seat width direction inner side. In other words, a part of the attached portion 13Aa (a portion of the attached portion 13Aa at the end of the planar member 11) abuts against the inner peripheral edge of the opening 11Aa (cutout) in the edge direction as an abutting wall. The same applies to the mounted portion 13Ba described later.

As shown in fig. 5, the contact structure of each of the upright wall portions 13Aa3 described above restricts the movement of the planar member 11 in the two-way positional displacement in the seat width direction (i.e., the edge direction) with respect to the front side curler 13A, and the cushion pad 3P can be appropriately supported from below by the planar member 11 at all times. More specifically, the vertical wall portions 13Aa3 are brought into contact with the left and right inner surfaces of the front opening 11Aa of the planar member 11, whereby the planar member 11 is appropriately restrained from moving inward in the seat width direction when a load is applied to the seated user, and movement of the planar member to the seat width direction is appropriately prevented. Further, each of the standing wall portions 13Aa3 also comes into contact with the left and right outer side surfaces of the planar member 11, whereby the movement of the planar member 11 toward the seat width direction outer side can be more appropriately prevented.

According to the above configuration, even when the planar member 11 receives a load biased toward the center or either of the left and right regions in the seat width direction due to kneeling of the seated person, the position is appropriately restricted so as not to be laterally displaced in each of the inner and outer directions in the seat width direction by the contact structure of the respective standing wall portions 13Aa 3. The upright wall portions 13Aa3 are provided in a state in which the planar member 11 is less likely to rise from the passage portions 12Aa of the mounting lines 12A due to the weight received by the planar member 11 from the cushion pad 3P provided on the upper side thereof, and therefore always maintain a state in which the planar member 11 is properly contacted from the lateral side.

The connecting portion 13Ab is formed in a shape of a half pipe having a hook-like shape along the curve of the fitting portion 13Aa1, in such a manner that the left fitting portion 13Aa1 of the right mounted portion 13Aa and the right fitting portion 13Aa1 of the left mounted portion 13Aa are integrally connected in a lateral arrangement.

Concerning the collar 13B on the rear side

Similarly, as shown in fig. 3 to 4, the rear collar 13B includes: a pair of laterally arranged attached portions 13Ba to which the left and right hook portions 12Bb of the pair of rear attachment wires 12B can be attached so as to be positioned in the seat width direction in a pair-by-pair manner; and a connecting portion 13Bb for integrally connecting the mounted portions 13Ba to each other. The pair of attached portions 13Ba arranged in the lateral direction described above respectively have: a pair of hook-shaped engagement portions 13Ba1 bent like a hook and having an extended shape, which can be integrally attached by individually pressing in the left and right hook portions 12Bb of the pair of rear mounting wires 12B from above and individually elastically click-engaging the left and right hook portions 12 Bb; a connecting surface portion 13Ba2 extending in the seat width direction so as to connect the linearly extending portions of the pair of fitting portions 13Ba1 in series; and standing wall portions 13Ba3 protruding forward from the fitting portions 13Ba1 along the shape of the mounting lines 12B fitted to the fitting portions 13Ba1, and coming into contact with lateral side surfaces of the planar member 11 on the rear edge side from the outer side or the inner side in the seat width direction. The rear pair of attached portions 13Ba also have fixed attachment portions 13Ba4 extending in the seat width direction so as to connect the rear end portions of the pair of fitting portions 13Ba1 in a series. Here, each standing wall portion 13Ba3 corresponds to a "regulating portion" of the present invention, a portion of each standing wall portion 13Ba3 which is in contact with the planar member 11 corresponds to a "contact wall" of the present invention, and each connecting surface portion 13Ba2 corresponds to a "pad supporting surface portion" of the present invention.

The left and right fitting portions 13Ba1 of the pair of laterally aligned attached portions 13Ba are each formed to have a structure having a substantially U-shaped cross section fitting groove into which the left and right hook portions 12Bb of the pair of rear side attachment wires 12B can be fitted so as to be sandwiched from both sides in the seat width direction, and a claw shape that is engaged by being elastically fitted to respective portions of the hook portions 12Bb by pressing the hook portions 12Bb into the fitting grooves so that the hook portions 12Bb are not disengaged from the fitting grooves. The fitting portions 13Ba1 are fitted to the left and right hook portions 12Bb of the rear pair of mounting wires 12B at the fitting portions 13Ba1, and are fitted to the rear tube 3Fd from above as described above in fig. 1 to 2 and 5.

As shown in fig. 5 and 8, the connecting surface portions 13Ba2 connecting the fitting portions 13Ba1 to each other in a series are formed in such a manner that the gaps Tr formed between the upper surface portions of the rear tubes 3Fd to be hooked in the fitting portions 13Ba1 and the rear edge portions of the planar members 11 are filled with flat surfaces smoothly connecting the planar members 11 and the upper surface portions of the rear tubes 3 Fd. According to the above configuration, as shown in fig. 8 to 9, each of the connecting surface portions 13Ba2 comes into contact with the bottom surface portion between the planar member 11 of the cushion pad 3P provided on the upper portion of the planar member 11 and the rear tube 3Fd in a state of surface contact from the diagonally lower rear side, and the bottom surface portion of the cushion pad 3P is supported by the surface shape smoothly connecting the planar member 11 and the rear tube 3Fd, so that the cushion pad 3P can be pressed so as not to escape from the gap Tr.

As shown in fig. 3 and 5, in each of the upright wall portions 13Ba3 extending forward from the fitting portions 13Ba1 along the shape of the mounting lines 12B, the end portions of the front ends extending forward along the shapes of the left and right hook portions 12Bb of the mounting lines 12B are bent in the seat width direction along the shapes of the mounting lines 12B bent from the hook portions 12Bb to the passing portions 12Ba, and are brought into contact with the side surfaces of the rear edge side of the planar member 11 facing the lateral side from the outer side or the inner side in the seat width direction. Similarly to the fitting portions 13Ba1, the upright wall portions 13Ba3 are formed in a shape having fitting grooves each having a substantially U-shaped cross section, into which the mounting wires 12B can be fitted in a manner sandwiched from both sides, and the upright wall portions sandwiching the passing portions 12Ba of the mounting wires 12B from the front and rear sides are brought into contact with the side surfaces of the rear edge side of the planar member 11 facing the lateral side from the outside or the inside in the seat width direction.

More specifically, among the above-described upright wall portions 13Ba3, the upright wall portion 13Ba3 extending forward from the right fitting portion 13Ba1 of the right mounted portion 13Ba and the upright wall portion 13Ba3 extending forward from the left fitting portion 13Ba1 of the left mounted portion 13Ba extend so as to be bent inward in the seat width direction along the shape of the corresponding mounting line 12B, and are brought into contact with the right outer side surface and the left outer side surface of the planar member 11 from the outer side in the seat width direction. As shown in fig. 7, the standing wall portion 13Ba3 extending from the left fitting portion 13Ba1 of the right mounted portion 13Ba to the front side and the standing wall portion 13Ba3 extending from the right fitting portion 13Ba1 of the left mounted portion 13Ba to the front side are respectively extended so as to be bent outward in the seat width direction along the shape of the corresponding mounting line 12B, and are respectively brought into contact with the right inner side surface and the left inner side surface of the opening 11Ba formed in the central portion of the rear edge side of the planar member 11 from the seat width direction inner side.

As shown in fig. 5, the contact structure of the respective standing wall portions 13Ba3 described above restricts the movement of the planar member 11 in the two-way positional displacement in the seat width direction with respect to the rear side collar 13B, and the planar member 11 can always properly support the cushion pad 3P from below. More specifically, the standing wall portions 13Ba3 are brought into contact with the left and right inner surfaces of the rear-side opening 11Ba of the planar member 11, whereby the planar member 11 is appropriately restrained from moving inward in the seat width direction when a load is applied to the seated user, and movement of the planar member to the seat width direction is appropriately prevented. Further, each of the standing wall portions 13Ba3 also comes into contact with the left and right outer side surfaces of the planar member 11, whereby the movement of the planar member 11 toward the seat width direction outer side can be more appropriately prevented.

As shown in fig. 4, the fixing portions 13Ba4 formed by connecting the rear end portions of the fitting portions 13Ba1 of the pair of rear mounted portions 13Ba in a series are configured to span between the fitting portions 13Ba1 by an inter-arrangement region connecting between rear end portions of the fitting portions 13Ba1 bent rearward and downward into a hook shape, and are formed to have a shape of an extended portion 13Ba4a extending in a plate shape forward and downward from each portion spanning between the fitting portions 13Ba 1. As shown in fig. 8, the extension portion 13Ba4a of each of the above-described fixed attachment portions 13Ba4 extends from the rear upper side to the front lower side in the lower region of the rear pipe 3Fd, and a resin-made J hook 3Ca is hooked and fixed from the rear side at the front end of the extension portion 13Ba4a, and the J hook 3Ca is coupled to the tip end portion of the cushion cover 3C drawn downward by the rear peripheral edge portion of the seat cushion 3.

The fixing portions 13Ba4 configured as described above are formed in such a manner as to be bridged between the fitting portions 13Ba1 by the both-end supporting structure, and thereby are set in a state of being bridged between the left and right hook portions 12Bb of the mounting wires 12B fitted to the fitting portions 13Ba1, and strongly supported by the hook portions 12 Bb. Thus, each of the fixedly attached parts 13Ba4 has a structural strength capable of strongly receiving the tension of the cushion cover 3C received from each of the J-hooks 3Ca hooked on each of the fixedly attached parts 13Ba 4.

According to the above configuration, even when the planar member 11 receives a load biased toward the center in the seat width direction or toward either of the left and right regions due to kneeling of the seated person, the position is appropriately restricted so as not to be laterally displaced in each of the inner and outer directions in the seat width direction by the contact structure of the respective standing wall portions 13Ba 3. The standing wall portions 13Ba3 are provided in a state in which the planar member 11 is less likely to rise from the passage portions 12Ba of the mounting lines 12B due to the weight received by the planar member 11 from the cushion pad 3P provided on the upper side thereof, and therefore always maintain a state in which the planar member 11 is properly contacted from the lateral side.

The connecting portion 13Bb is formed in a shape of a half pipe shape which is curved along the fitting portion 13Ba1 and has a hook-like shape, and integrally connects the left fitting portion 13Ba1 of the right mounted portion 13Ba and the right fitting portion 13Ba1 of the left mounted portion 13Ba in a lateral arrangement.

About the erection part 13C

As shown in fig. 3 to 4, the bridge portion 13C is formed in a configuration integrally connecting the rear edge portion of the front ferrule 13A and the front edge portion of the rear ferrule 13B, which are bent downward, in a substantially ladder-like shape in a plan view. Specifically, the bridge portion 13C is formed to have a first bridge portion 13C1 and a second bridge portion 13C2, in which the first bridge portion 13C1 extends in a substantially H shape in plan view from a rear edge portion located close to the two inner fitting portions 13Aa1 located on the inner side in the seat width direction of the left and right connecting surface portions 13Aa2 of the above-described front grommet 13A toward the rear side, and the second bridge portion 13C2 extends in a width-expanded form extending outward in the seat width direction across both rear ends of the H shape of the first bridge portion 13C1, and a front end extending therefrom extends in a form connected to a front edge portion located close to the two outer fitting portions 13Ba1 located on the outer side in the seat width direction of the left and right connecting surface portions 13Ba2 of the rear grommet 13B.

The first bridging portion 13C1 is formed in a shape of being bent downward into a valley shape as a whole in a form of a bent line with a connecting portion bridging in the H-shaped lateral direction (see fig. 8). As shown in fig. 3 to 4, a substantially C-shaped hooking portion 13C3 is formed to extend outward in the seat width direction from the connecting portion of the first bridging portion 13C1 extending in the H-shaped lateral direction. These hooking portions 13C3 are portions where the front end portion of the lower end side of the not-shown back cover covering the back surface of the seat back 2 described above in fig. 1, which is drawn in toward the front lower side, is hooked and fixed from the lower side via a not-shown rubber band.

As shown in fig. 3 to 4, the mounting hole 13C4 penetrating in the height direction is formed at each of the first bridging portion 13C1 and the second bridging portion 13C 2. These mounting holes 13C4 function as mounting portions for fixing various harnesses W/H routed through the lower region of the planar support body 10 by being inserted from below using clips CL. As shown in fig. 8, the bridge portion 13C is formed to be bent downward as a whole and is configured to connect the front side collar 13A and the rear side collar 13B, and is provided so as to be separated downward from the rear surface of the planar member 11. Thus, as shown in fig. 9, the bridge portion 13C is configured to be difficult to interfere with the planar member 11 even if the planar member 11 is pushed downward by a load of a seated user. The mounting hole 13C4 and the clip CL are also configured to be less likely to interfere with the planar member 11 by being disposed in a region on the back surface side (lower side) opposite to the front surface side (upper side) facing the seat surface of the planar member 11. Here, each mounting hole 13C4 corresponds to a "fixing portion" of the present invention, and the clip CL inserted into and mounted to these mounting holes 13C4 corresponds to a "peripheral member" of the present invention.

Therefore, the clips CL of the harnesses W/H inserted into the mounting holes 13C4 of the bridging portion 13C from below are mounted so as to project upward from the mounting holes 13C4 to some extent, and are also hard to interfere with the planar member 11. Thus, the respective harnesses W/H can be appropriately arranged in the region directly below the planar member 11 without having an excessive extra length for avoiding interference between the harnesses W/H and the planar member 11.

Summary of the invention

As described above, in the seat 1 of the present embodiment, the movement of the planar member (11) in the edge direction (seat width direction) is restricted by the restricting portions (13Aa3, 13Ba3) provided in the intervening members (13A, 13B), and thereby the movement of the planar member (11) in the edge direction with respect to the mounting lines (12A, 12B) can be suppressed.

Further, the function of the regulating portions (13Aa3, 13Ba3) can be realized by a contact wall (a portion of the upright wall portion 13Aa3 which is in contact with the planar member 11) having a simple structure which is in contact with the planar member (11) only from the edge direction (the seat width direction).

Further, the abutting walls of the regulating portions (13Aa3, 13Ba3) are brought into abutment with the opening portions (cutout portions 11Aa, 11Ba) located in the middle portion, not the outer end portions in the edge direction (seat width direction) of the planar member (11), from the inside, whereby the movement of the planar member 11 in the edge direction can be appropriately suppressed.

The attached portions (13Aa, 13Ba) having a function of holding the attachment portions (hook portions 12Ab, 12Bb) extending from the attachment wires (12A, 12B) toward the seat frame (seat cushion frame 3F) also have a function of abutting against the inner peripheral edge of the opening portions (cutout portions 11Aa, 11Ba) of the planar member 11 to suppress movement of the planar member 11. With such a rational structure, the sheet-like member 11 can be prevented from moving in the edge direction while avoiding as much as possible an increase in size of the interposed members (13A, 13B).

In the seat 1 of the present embodiment, when a plurality of attachment wires (12A, 12B) are provided at the edge of the planar member (11), the attachment wires (12A, 12B) can be collectively held by the intervening members (13A, 13B), and the intervening members (13A, 13B) can be attached to the seat frame (seat cushion frame 3F). This allows the plurality of attachment wires to be easily attached while being appropriately positioned at a predetermined position of the seat frame (the seat cushion frame 3F).

Further, the cushion support surface portions (the connecting surface portions 13Aa2, 13Ba2) provided in the intermediate members (13A, 13B) can prevent the escape of the seat cushion (3P) when a load of a seated person is applied, and the riding comfort can be improved more appropriately than in the case where the cushion support surface portions (the connecting surface portions 13Aa2, 13Ba2) are provided as members different from the intermediate members (13A, 13B).

In addition, the seat cover (3C) can be fixed reasonably and firmly by using the connecting surface portion (13Ba4) provided on each of the mounted portions (13Ba) of the intermediate member (13B) as a fixing and attaching portion of the seat cover (3C).

Further, the plurality of mounting wires (12B) are positioned with respect to the seat frame (seat cushion frame 3F) by any one of the first intermediate member (13A) and the second intermediate member (13B), and thus the plurality of mounting wires (12A) are also positioned with respect to the seat frame (seat cushion frame 3F) by the other intermediate member (13A) connected to the one intermediate member (13B). Therefore, the plurality of attachment wires (12A, 12B) can be more easily attached to the seat frame (cushion frame 3F).

Further, the cushion support surface portions (13Aa2, 13Ba2) provided on the intervening members (13A, 13B) can prevent the seat cushion (3P) from escaping (displacing) so as to be pushed out through the gaps (Tf, Tr) between the planar member (11) and the seat frame (3F).

Further, the pad support surface portions (13Aa2, 13Ba2) can appropriately fill in gaps (Tf, Tr) formed between the pair of hook portions (12Ab, 12Bb) of the mounting lines (12A, 12B) and appropriately suppress displacement of the seat pad (3P).

Further, the cushion support surface portions (13Aa2, 13Ba2) are provided in a bridge shape that blocks between the pair of hook portions (12Ab, 12Bb) of the mounting wires (12A, 12B), whereby the seat cushion (3P) can be more appropriately received by the cushion support surface portions (13Aa2, 13Ba 2).

Further, by providing a fixing portion (mounting hole 13C4) capable of fixing the peripheral member (clip CL) in a region on the back side of the planar member (11), the fixing portion (13C4) is not exposed on the front side of the planar member (11). Therefore, the fixing portion (13C4) can be attached to the planar support body (10) in a manner that is less likely to impair the riding comfort of the vehicle seat (1).

Further, even if the planar member (11) deflects toward the rear surface side upon receiving a load from the seat surface, it is difficult to interfere with the fixing portion (13C 4). Therefore, the peripheral member (CL) can be mounted on the planar support body (10) in a manner that is more difficult to damage the riding comfort of the vehicle seat (1).

Further, since the bridging portion (13C) connecting the first and second intermediate members (13A, 13B) supports both ends of the intermediate members (13A, 13B), the structural strength is high. Therefore, by providing the fixing portion (13C4) to such a bridge portion (13C), the peripheral member (CL) can be fixed more firmly.

(related to other embodiments)

While the embodiments of the present invention have been described above using one example, the present invention can be implemented in various ways in addition to the above examples.

For example, the vehicle seat according to the present invention can be widely applied to a seat for a vehicle other than an automobile such as a railroad, an airplane, a ship, or other vehicles. The configuration of the present invention can be applied to a seat cushion of a vehicle seat, and can also be applied to a seat back.

The planar support body may be configured to be stretched in the seat width direction, in addition to being stretched in the front-rear direction over the frame-shaped seat cushion frame 3F forming the framework of the seat cushion. Further, the seat back frame may be configured to be erected in the height direction on a frame-like back frame forming a framework of the seat back, or may be configured to be erected in the seat width direction.

The flexible planar member forming the planar support surface may be formed of a flexible surface material other than a textile material such as a leather material. The mounting wire for mounting the edge portion of the planar member on the end side to be bridged on the seat frame may be mounted on the seat frame by other mounting structures such as a structure of being locked with a locking claw or being mounted by caulking, in addition to being hooked on a hook of the seat frame. In addition, the mounting lines may be 3 or more arranged in a lateral array, or may be only one. The seat frame to which the mounting wire is attached may be configured by a frame member other than a round pipe such as a square pipe or a plate. The seat frame may be configured as, for example, a circular tube that connects lifter rods constituting the seat lifter to each other, or may be configured to rotate with respect to a mounting spool that is hooked on the circular tube via an interposed member made of resin.

Further, the resin-made insert may be mounted to the seat frame without being integrally fitted to the mounting wire. The restriction portion formed in the intermediate member for restricting the lateral movement of the planar member may be a contact wall which contacts the planar member from the lateral direction to prevent the movement, or may be a structure which restricts the lateral movement of the planar member by a sliding frictional resistance generated between the planar member and the planar member by being pressed against the surface of the planar member, or a structure which restricts the lateral movement of the planar member by sandwiching the planar member in the thickness direction. In addition, the mounting lines may be 3 or more in number arranged in a horizontal row. In addition, the mounting lines may be arranged in a horizontal row by 3 or more or only 1.

In the case where the restriction portion for restricting the lateral movement of the planar member is configured to restrict the movement by coming into contact with the planar member from the lateral direction, for example, the restriction portion may be configured to restrict at least one of the lateral movements of the planar member. The regulating portion may be configured to abut only from both lateral outer sides of the planar member, abut only from both inner sides to an inner peripheral edge of an opening portion formed in a middle portion of the passage opening of the planar member, or be configured to regulate lateral movement only at an edge portion on one end side on which the planar member is provided. The opening formed in the middle of the passage opening of the planar member may not necessarily be formed in the lateral center of the planar member, and may be formed in a position offset from the center.
