Detailed Description

According to the needs, the specification of the utility model discloses the concrete embodiment of the utility model; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. The same or similar reference numerals may indicate the same parameters and components or similar modifications and substitutions thereto. In the following description, various operating parameters and components are described in various embodiments as contemplated. These specific parameters and components are used in this specification as examples only and are not meant to be limiting. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

Conventional vehicle seats provide a three-point restraint system. When a vehicle user includes a child or infant, it is necessary to carry an additional booster pad or safety seat and secure it to the vehicle seat for use by the child or infant. In such a case, the conventional three-point restraint system is not used, and additional restraint devices need to be purchased, carried and installed, so that the entire restraint requirement requires additional costs and installation and removal processes, thereby causing inconvenience to users.

Embodiments of the present application aim to solve at least one of the above-mentioned technical problems, and provide a vehicle seat with improved convenience. The seat has three locking modes corresponding to an adult, a child, and an infant, respectively, and can provide a desired locking mode or a restraint form according to a user type without an additional restraint device.

Fig. 1-2 illustrate a vehicle seat 100 according to one embodiment of the present application, wherein the seat 100 is in an unused mode and a first locked mode, respectively. Referring to fig. 1-2, a seat 100 includes a seat cushion 110, a backrest 120, and a safety system 130. The seat cushion 110 has two opposite ends in the vehicle longitudinal direction L, for example, a front end 111 and a rear end 112, the front end 111 corresponding to the vehicle front direction, and the rear end 112 corresponding to the vehicle rear direction. A backrest 120 is attached to the rear end 112. The seat cushion 110 has two sides, e.g., a first side 113 and a second side 114, that are opposite in the vehicle width direction W.

The restraint system 130 may include a first safety belt 131, a latch plate 132 slidably connected to the first safety belt 131, and a buckle 133 releasably engaged with the latch plate 132. The first belt 131 is retractably connected to a retractor (not shown, which may be fixed to the vehicle body structure at or near the upper portion of the backrest 120) with a first end 135 secured to the retractor and a second end 136 secured to one side of the seat cushion 110, such as the second side 114. The first safety belt 131 may extend through a slot (not shown) in the latch plate 132 so that the latch plate 132 can slide between the two ends of the first safety belt 131. The insert button 133 and the second end 136 of the first safety belt 131 are respectively connected to two sides of the seat cushion 110, for example, the insert button 133 is located on the first side 113, and the second end 136 is fixed to the second side 114. The buckle 133 may include a slot (not shown) that may receive and restrain the latch plate 132 and a button (not shown) that may be configured to be depressed to release the latch plate 132 from the slot.

Fig. 3 is a perspective view of the seat 100 during switching from the non-use mode to the second locked mode. Referring to fig. 3, the backrest 120 includes a main body portion 121 and a deformation portion 122. The main body 121 and the deformable portion 122 are both connected to the rear end 112 of the seat cushion 110, and the deformable portion 122 is closer to the front end 111 of the seat cushion 110 than the main body 121. Deformation 122 may be releasably engaged with body portion 121 in any suitable manner to fit over front surface 123 (see fig. 2) of body portion 121. For example, the upper portion of deformation portion 122 or the upper portion of body portion 121 may be provided with a locking device such as a sticky note, a snap, a push-lock mechanism, an interference fit locking mechanism, or the like, to enable releasable engagement of the two.

Referring to fig. 2, when the seat 100 is in the first locked mode, the deformation portion 122 of the backrest 120 fits against the main body portion 121 and the latch plate 132 engages with the buckle 133, a first segment 137 (e.g., a portion located above the seat cushion 110, i.e., a portion between the first end 135 and the latch plate 132 or the buckle 132, also referred to as a shoulder strap) of the first harness 131 is used to restrain the upper half of the adult user, and a second segment 138 (e.g., a portion spanning across the seat cushion 110, i.e., a portion between the latch plate 132 or the buckle 133 and the second end 136, also referred to as a belly strap) is used to restrain the abdomen of the adult user.

Referring to fig. 1-3, the deformation 122 includes two substantially equal portions, such as a first deformation 124 and a second deformation 125. In the first locking mode, the first deformation 124 is located above the second deformation 125. Referring to fig. 3, the deformation portion 122 may be folded with respect to a transverse centerline a thereof, which may be parallel to the width direction W. The deformation 122 may be provided with a folding facilitating structure, such as a crease, a press seam, a hinge structure, a pivot structure, etc., at its transverse centerline a, such that the first deformation 124 may be folded or flipped along the transverse centerline a toward the second deformation 125. The second deforming portion 125 may be connected to a lower portion of the main body portion 121 by a pivotal connection mechanism (not shown), thereby being pivotable toward the seat cushion 110 at the rear end 112 of the seat cushion 110 along an axis B substantially parallel to the transverse centerline a.

In the process of switching from the unused mode to the second lock mode, the deformation portion 122 can be folded along its transverse centerline a and pivoted toward the seat cushion 110 at the rear end of the seat cushion 110. In other words, the first deformable portion 124 pivots toward the seat cushion 110 at the transverse centerline a until it engages the lower surface of the second deformable portion 125, and at the same time or thereafter, the first deformable portion 124 pivots toward the seat cushion 110 with the second deformable portion 125 until the first deformable portion 124 contacts or is supported by the upper surface 115 of the seat cushion 110, as shown in fig. 4. In this way, the deformation portion 122 is changed such that the first deformation portion 124 and the second deformation portion 125 stacked in the height direction H are supported on the seat cushion 110, and an additional seat cushion height can be provided, similar to a booster cushion mounted on a conventional vehicle seat.

In some embodiments, the thickness T1 of deformation 122 may be in the range of about 20mm to about 80mm, such as in the range of about 40mm to about 70mm, such as 65 mm. In this way, the folded deformation 122 may provide additional height of H1 on the seat cushion 110, H1 ≈ 2T 1. H1 may be in the range of about 40mm to about 160mm, for example about 80mm to about 140mm, such as 130 mm.

Referring to fig. 3-4, the seatbelt system 120 may further include a support 126 disposed on the deformation 122. The support member 126 may be two foldable legs provided on a surface of the first deforming part 124 facing the body part 121. In the non-use mode and the first locking mode, the support 126 is sandwiched between the body portion 121 and the deformation portion 122 of the backrest 120, not visible to the user. The legs can be folded to conform to the surface of the first deformation 124, thereby reducing the likelihood that they will affect the appearance or comfort of the seat in the non-use mode and the first locked mode. In the second locked mode, the support 126 moves into contact with the upper surface 115 of the seat cushion 110 as a result of the folding and pivoting of the first deformation 124, thereby supporting the deformation 122 on the seat cushion 110 and providing an additional cushion height H2, H2 may be in the range 0 to 30mm, for example 5mm to 15mm, such as 10 mm.

In some embodiments, referring to fig. 3, using both the deformation 122 and the support 126, the additional cushion height that can be provided can be approximately the sum of H1 and H2. In some embodiments (not shown), using only the deformation 122, additional cushion height may be provided that is approximately H1 or 2T 1.

When the seat 100 is in the second locked mode, the latch plate 132 is engaged with the catch 133, the deformation 122 of the backrest 120 is folded and pivoted to the support 126 supported on the seat cushion 110, and the first harness 131 provides similar restraint protection as the first locked mode, for example the first section 137 for restraining the upper body of a child user and the second section 138 for restraining the abdomen of a child user. In this way, the deformation and/or the support constitute a heightening structure on the seat cushion (similar to a heightening pad mounted on a conventional vehicle seat), making it possible to use the three-point restraint system of the seat itself directly for the child, without carrying and mounting additional restraint devices, such as a heightening pad.

FIG. 5 is a schematic view of the seat 100 during switching from the unused mode to the second locked mode showing the side guards of the seat belt system. Referring to fig. 5, main body portion 121 of backrest 120 has long grooves 210 at both ends in width direction W, and long grooves 210 extend in longitudinal direction L1 of the backrest at the front surface of main body portion 121. The seat belt system 130 further includes a first side guard 212 and a second side guard 213 disposed on either side of the backrest 120. The first side protector 212 and the second side protector 213 may be two guards, respectively, and the second side protector 213 is located above the first side protector 212.

Referring to fig. 1 and 5, in the non-use mode, first side guard 212 and second side guard 213 are both received in slot 210 and are not visible to a user. In the second locked mode, the first side guard 212 may be pivoted by a pivot mechanism (not shown) toward the seat cushion 110 to contact or bear against both sides of the upper surface 115 of the seat cushion 110, thereby providing further restraint protection to the legs of the child user; the second side protector 213 may be pivoted to the seat cushion 110 by a pivot mechanism (not shown) to be supported on the upper sides of the main body portion 121, thereby providing further restraint protection to the head of the child user.

Fig. 6 shows the seat 100 in a third locked mode. Referring to fig. 6, the seat belt system 130 further includes two guide members 310 provided on the body portion 121 of the backrest 120, a second seat belt 311, and a joint member 312 fixed to the second seat belt 311. The two guide members 310 are separately provided on the front surface 123 of the main body portion 121 and have substantially the same height with respect to the seat cushion 110, which may be set higher than the shoulder of the infant user when the infant user sits on the folded and pivoted deformation portion 122.

Fig. 7 is a perspective view of the guide 310. Referring to fig. 6-7, the guide member 310 has a first slot 313 through which the first safety belt 131 passes, the first slot 313 being configured to allow the first safety belt 131 to slide freely therein, the first safety belt 131 being accessible to the first slot 313 through a first notch 314 communicating with the first slot 313. In one embodiment, the guide member 310 further includes a first closing member 315 disposed adjacent the first notch 313, the first closing member 315 being movable away from the guide member 310 to open the first notch 314 so that the first safety strap 131 may enter the first slot 313 through the first notch 314 and also to close the first notch 314 to trap the first safety strap 131 in the first slot 313.

The second safety belt 311 has one end fixed to the deformation portion 122 of the backrest 120, for example, to the surface of the second deformation portion 125 facing the body portion 121, and the other end connected to an engagement member 312, the engagement member 312 being releasably engageable with the first safety belt 131. In this way, in the non-use mode, the guide 310, the second safety belt 311, and the engagement piece 312 are positioned between the deformation portion 121 and the main body portion 121, and are covered by the deformation portion 122, and are not visible to the user.

Fig. 8 shows a perspective view of the joint 312. Referring to fig. 8, the engagement member 312 has a second slot 316 through which the first safety belt 131 passes, the second slot 316 being configured to allow the first safety belt 131 to slide freely therein, and the first safety belt 131 can enter the second slot 316 through a second notch 317 communicating with the second slot 316. In one embodiment, the engagement member 312 further includes a second closure member 318 disposed adjacent the second notch 317, the second closure member 318 being movable away from the engagement member 312 to open the second notch 317 to allow the first safety strap 131 to enter the second slot 316 through the second notch 317 and also to close the second notch 317 to trap the first safety strap 131 in the second slot 316.

Referring to fig. 6 to 8, when the seat 100 is in the third locking mode, the latch plate 132 is engaged with the buckle 133, the deformation portion 122 of the backrest 120 is folded and pivoted to be supported on the seat cushion 110, the first segment 137 of the first seat belt 131 passes through the two guide members 310 in sequence and the second seat belt 311 is engaged with the portion 400 of the second seat belt 311 between the two guide members 310 through the engaging piece 312, and the first side protector 212 and the second side protector 213 are pivoted to the outside of the main body portion 121. In other words, when switching to the third locking mode, the first segment 137 of the first safety belt 131 can be made to enter the first groove 313 through the first notch 314, and the first groove 313 is closed with the first closing member 315 to restrain the first safety belt 131 in the first groove 313, so that the first safety belt 131 passes through the two guides 310 in sequence. Next, the portion 400 of the first safety belt 131 between the two guides 310 is brought into the second slot 316 through the second notch 317 and the second notch 317 is closed with the second closing member 318, thereby trapping the portion 400 of the first safety belt 131 in the second slot 316 and engaging the second safety belt 311 at substantially the middle point of the portion 400.

When the seat 100 is in the third locked mode, the portion 400 of the first segment 137 of the first safety belt 131 forms a V-shape due to engagement with the second safety belt 311 at its mid-position, the belt portions corresponding to the two sides of the V-shape may respectively straddle the two shoulders of the infant user, forming a shoulder strap to provide restraint protection for the upper body of the infant user, and the second segment 138 straddles the abdomen of the infant user to provide restraint protection for the abdomen. In this way, the belt system 130 can be used as a five-point belt, i.e., it has five contact points with the vehicle, which are located at two positions on the main body portion 121 corresponding to the two guides 310, at which the second end portion 136 of the first belt is fixed, at which the buckle is located, and at which the deformation portion 122 is connected to the second belt 311.

It should be understood that a child in this application may include users between the ages of 0 and 4, and an infant may include users between the ages of 3 and 12, but age is not the only factor limiting the use of the second and third locking modes, as the user may also make a reasonable choice based on other parameters (e.g., the user's height and weight, etc.). For example, the second locking mode may be used for a larger sized infant user and the third locking mode may be used for a smaller sized child user.

According to the vehicle seat of the embodiment of the present invention, in the non-use mode and the first locking mode, the appearance is similar to that of a conventional seat; in the second and third locking modes, a portion of the seat back may deform and move to the seat cushion to provide additional seat cushion height, and the seat belt system may provide three-point restraint or five-point restraint as desired by the user. In this way, the seat can meet the needs of adult, child, and infant users at the same time, and additional restraint devices can be avoided from being carried, installed, and removed in the vehicle for the child and infant, thereby reducing the cost of the seat and increasing the convenience of use.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
