尚、符号８は座布団に被せるカバーである。 FIG. 1 and FIG. 2 are a plan view and a longitudinal sectional view showing a first embodiment of a driver's ball seat cushion based on the prior art, which is a prerequisite for explaining the seat cushion of the present invention. A space portion S is provided between a seat plate 1 on which a person sits and a support plate 2 in contact with a vehicle seat as shown in FIG. 5, and swing function portions 3, 3, 3 are provided in at least three locations of the space portion S. The swing function parts 3, 3, 3 are arranged between the lower support 5, the upper support 4 a facing the lower support 5, and the upper and lower supports 4 a, 5 a. Among them, the lower support 5a is provided with an upward dish-like surface 11b, and the upper support 4a is provided with a downward dish-like surface 11a. Further, the sphere 6 has upper and lower dish-like surfaces. 11a and 11b, and will roll in any direction depending on the driver's will. After the sphere 6 rolls in an arbitrary direction, the drowsiness and fatigue during driving are taken by swinging the seat plate 1 by returning to the initial position by using the gradient of the dish-like surfaces 11a and 11b. It is. Further, the seat plate 1 is not shaken by a restraining means 9 beyond a certain range with respect to the support plate 2.
Reference numeral 8 denotes a cover that covers the cushion.

揺動機能部３は図３のように、上支持体４ａ及び下支持体５ａと球体６とからなるものであるが、このうち、まず下支持体５ａの上向き皿状面１１ｂは、外周部から中心部に向けて下降傾斜して半球面状をなし、さらに該下支持体５ａと支持板２との固定は、該下支持体５ａの下端部外周の全周に備えた張出片を前記支持板３の天面側に当接し、さらに当接部分の複数箇所にビス止めをしている。次に上支持体４ａの下向き皿状面１１ａは、外周部から中心部に向けて上方に傾斜して半球面状をなし、さらに，上支持体４ａの上端部外周に備えた張出片を座板１の裏面側に当接し、さらに当接部分の複数箇所にビス止めをしたものである。そして球体６は、上下支持体４ａ，５ａの各皿状面１１ａ，１１ｂ間に介在し、座布団の未使用時には、上支持体４ａと下支持体５ａの各々の中心部、即ち、上向き皿状面１１ｂの最下部と下向き皿状面１１ａの最上部との双方にそれぞれ接し、本座布団の使用時には、各々の皿状面１１ａ，１１ｂの中心を基準とする全方位に向けて任意に転がらせることを自在としている。 As shown in FIG. 3, the swing function part 3 is composed of an upper support 4a, a lower support 5a, and a sphere 6. Of these, the upward dish-shaped surface 11b of the lower support 5a The lower support 5a and the support plate 2 are fixed to the lower support 5a by using a protruding piece provided on the entire outer periphery of the lower end of the lower support 5a. It abuts on the top surface side of the support plate 3, and is further screwed at a plurality of abutting portions. Next, the downward dish-like surface 11a of the upper support 4a is inclined upward from the outer peripheral portion toward the central portion to form a hemispherical shape, and further, a protruding piece provided on the outer periphery of the upper end portion of the upper support 4a is provided. This is in contact with the back surface side of the seat plate 1, and is further screwed at a plurality of contact portions. The spherical body 6 is interposed between the dish-like surfaces 11a and 11b of the upper and lower support bodies 4a and 5a. When the cushion is not used, the center part of each of the upper support body 4a and the lower support body 5a, that is, an upward dish shape. Both the lowermost part of the surface 11b and the uppermost part of the downwardly facing dish-like surface 11a are in contact with each other, and when using this cushion, it is arbitrarily rolled toward all directions with the center of each of the dish-like surfaces 11a and 11b as a reference. It is free.

また拘束手段９は、支持板２を基準とする一定範囲内での座板２の全方位への揺動を可能とし、しかも、それ以上広い範囲での揺れを規制するものであり、具体的には、座板１と支持板２とにゴム紐９を結びつけている。そして図６（ａ）（ｂ）（ｃ）のように、座板１が運転者の腰の動きに追従して揺れ動いた場合、球体６が上下各皿状面１１ａ，１１ｂの間を転がり、各皿状面１１ａ，１１ｂにおける最大転がり位置にまで到達した段階で、ゴム紐９の伸びが限界となる。これによって座板１の揺れも最大移動位置に達し、その後は、球体６が各皿状面１１ａ，１１ｂの初期位置へ復帰するとともに、ゴム紐９も縮むことで、座板１も支持板２と重なり合う位置に戻る。
尚、図中の符号１８は、ゴム紐９を座板１座面と面一とする切欠部である。 Further, the restraining means 9 enables swinging of the seat plate 2 in all directions within a certain range with respect to the support plate 2, and restricts swinging in a wider range. Further, a rubber string 9 is tied to the seat plate 1 and the support plate 2. Then, as shown in FIGS. 6A, 6B, and 6C, when the seat plate 1 swings following the movement of the driver's waist, the sphere 6 rolls between the upper and lower dish-like surfaces 11a and 11b, At the stage where the maximum rolling position is reached on each of the dish-like surfaces 11a and 11b, the elongation of the rubber cord 9 becomes the limit. As a result, the swing of the seat plate 1 reaches the maximum movement position, and thereafter, the sphere 6 returns to the initial position of each of the dish-like surfaces 11a and 11b, and the rubber cord 9 is also contracted, so that the seat plate 1 and the support plate 2 are also retracted. Return to the position where it overlaps.
Reference numeral 18 in the drawing is a notch portion in which the rubber cord 9 is flush with the seating surface of the seat plate 1.

ストッパー７は図４（ａ）（ｂ）のように、本座布団の中央部に備えた切替ツマミ１２の操作によって、底面側に半円状の開放口２２を有するケース体１４の内部に備えたドラム１５が横回転し、このドラム１５は右半分が磁石部分２０、そして左半分が樹脂部分２１で構成してある。そして前記切替ツマミ１２を「ＯＮ」の位置にひねることで、該ケース体１４の開放部分にドラム１５の磁石部分２０が位置し、この磁石部分２０が、支持板２天面側の中央部に固着した金属板１６に吸い付く。また切替ツマミ１２を「ＯＦＦ」の位置にひねれば、ドラム１５の樹脂部分２１がケース体１４の開放口２２に位置し、これにより、磁石部分２０の磁力が遮られ、座板１を支持板２から自由に揺らせる状態となる。 As shown in FIGS. 4A and 4B, the stopper 7 is provided inside the case body 14 having a semicircular opening 22 on the bottom side by the operation of the switching knob 12 provided in the center portion of the main cushion. The drum 15 is rotated laterally, and the drum 15 includes a magnet portion 20 on the right half and a resin portion 21 on the left half. Then, by twisting the switching knob 12 to the “ON” position, the magnet portion 20 of the drum 15 is located at the open portion of the case body 14, and this magnet portion 20 is located at the center portion on the top surface side of the support plate 2. It sticks to the fixed metal plate 16. Further, when the switching knob 12 is twisted to the “OFF” position, the resin portion 21 of the drum 15 is positioned at the opening 22 of the case body 14, whereby the magnetic force of the magnet portion 20 is blocked and the seat plate 1 is supported by the support plate. It will be in the state which shakes freely from 2.

図７（ａ）（ｂ）は本座布団の第２実施形態を示し、図８及び図９（ａ）（ｂ）は本発明の第３実施形態を示すものである。まず第２実施形態のものは、揺動機能部３を構成する上支持体４ａと下支持体５ｃとに、横長の皿状面１１ｃを形成してあり、この皿状面１１ｃに球体６を接触することで、該球体６は皿状面１１ｃの左右方向のみに転がるようになる。 FIGS. 7 (a) and 7 (b) show a second embodiment of the present cushion, and FIGS. 8 and 9 (a) and 9 (b) show a third embodiment of the present invention. First, in the second embodiment, a horizontally long dish-like surface 11c is formed on an upper support 4a and a lower support 5c constituting the swing function part 3, and a sphere 6 is placed on the dish-like surface 11c. By contact, the sphere 6 rolls only in the left-right direction of the dish-like surface 11c.

次に第３実施形態のものは図８のように、同じく揺動機能部３を構成する上支持体４ｂと下支持体５ａとに、周壁の一辺が切り立った半円形の皿状面１１ｄを形成するものであり、この切り立った箇所は、本座布団を座席１３に載せた際、自動車の進行方向側に位置させる。これにより、走行中に運転者が眠気や疲労感を感じた場合は、他の実施形態のもののように、運転者が意図的に腰を動かして座板１を任意方向に揺り動かすことができるのは勿論のこと、万一、本座布団の使用中に急ブレーキをかけるような事態に陥った際でも、図９（ａ）（ｂ）のように、図中Ｆ位置において座板１の揺れが静止し、球体６が皿状面１１ｄから抜け出して座板１と共に飛び出す危険が回避される。また第３実施形態に適用した上支持体４ｂは、座板１と球体６とが一体的な形態をなしており、この上支持体４ｂの構成は具体的に、座板１の裏面側において上下方向に貫通孔を有する円筒状支持部１９を備え、さらに該円筒状支持部１９の下端側開口部に、球体６を回転が自由な状態で保持したものである。 Next, in the third embodiment, as shown in FIG. 8, the upper support 4b and the lower support 5a, which also form the swing function portion 3, are provided with a semicircular dish-like surface 11d with one side of the peripheral wall standing upright. This formed portion is positioned on the traveling direction side of the automobile when the seat cushion is placed on the seat 13. As a result, when the driver feels drowsiness or fatigue during traveling, the driver can intentionally move his / her waist and swing the seat plate 1 in any direction, as in other embodiments. Needless to say, even if a sudden braking occurs while using the main cushion, the seat plate 1 sways at the position F in the figure as shown in FIGS. 9 (a) and 9 (b). The danger that the sphere 6 is stationary and the spherical body 6 comes out of the dish-like surface 11d and jumps out together with the seat plate 1 is avoided. Further, the upper support 4b applied to the third embodiment has a configuration in which the seat plate 1 and the sphere 6 are integrated, and the configuration of the upper support 4b is specifically on the back side of the seat plate 1. The cylindrical support part 19 which has a through-hole in an up-down direction is provided, and also the spherical body 6 is hold | maintained in the lower end side opening part of this cylindrical support part 19 in the state which can rotate freely.

また図１０（ａ）（ｂ）（ｃ）のように、上支持体４ｂと下支持体５ａとのそれぞれに半円形状をなす皿状面１１ｄ，１１ｄを、当該各皿状面１１ｄ，１１ｄにおける切り立った一辺側を相反する方向に向けて備えてもよく、使用時には、球体６が図中のＦ位置からＲ位置までの範囲内を自由に揺り動かすことができると共に、万一、使用時に急ブレーキをかけるような事態に陥った場合でも、各皿状面１１ｄ，１１ｄの切り立った一辺間に挟まれ、図中のＦ位置において転がりを止め、前述の第３実施形態と同様に、座板１の飛び出しを回避できる（第４実施形態）。さらに図１１（ａ）（ｂ）は、本座布団の第５実施形態を示し、この座布団は、座板１の底面側における自動車進行方向側の端部に下向きの凸部２３ａを、また支持板２の天面側における自動車進行方向側の端部に上向きの凸部２３ｂをそれぞれ設け、万一の急ブレーキ時に備えて、下向き凸部２３ａと上向き凸部２３ｂとの当接時において、それ以上の座板１の自動車進行方向への揺れ動きを規制したものである。また図１２（ａ）（ｂ）のように、座板１と支持板２との間、つまりは空間部Ｓを掛け渡すように面ファスナー２４ａ，２４ｂを張り付けることで、未使用時の座板１の揺れを静止している（第６実施形態）。
尚、前述の第３実施形態で使用した上支持体４ｂは、この第３実施形態の座布団に限らず、本発明において想到される様々な形態のものに適用できる。 Further, as shown in FIGS. 10A, 10B, and 10C, the dish-shaped surfaces 11d and 11d having a semicircular shape are formed on the upper support 4b and the lower support 5a, respectively. The sphere 6 can be freely swung within the range from the F position to the R position in the figure, and in the unlikely event that it is suddenly used during use. Even in the case where the brake is applied, it is sandwiched between the raised sides of the respective plate-like surfaces 11d, 11d, and stops rolling at the position F in the drawing. As in the third embodiment, the seat plate 1 can be avoided (fourth embodiment). Further, FIGS. 11 (a) and 11 (b) show a fifth embodiment of the present cushion, which has a downwardly projecting portion 23a at the end of the bottom surface side of the seat plate 1 on the vehicle traveling direction side, and a support plate. 2 is provided with an upward convex portion 23b at the end of the vehicle traveling direction side on the top surface side of the vehicle 2, and in case of sudden braking, when the downward convex portion 23a and the upward convex portion 23b contact each other The swinging movement of the seat plate 1 in the vehicle traveling direction is regulated. Further, as shown in FIGS. 12 (a) and 12 (b), the seat fasteners 24a and 24b are pasted between the seat plate 1 and the support plate 2, that is, across the space portion S, so that the seat when not in use is used. The shaking of the plate 1 is stationary (sixth embodiment).
The upper support 4b used in the third embodiment described above is not limited to the seat cushion of the third embodiment, and can be applied to various forms conceived in the present invention.

また本発明の第１実施形態は図１３と図１４（ａ）（ｂ）（ｃ）のように、上向き窪み面１１ｅと下向き窪み面１１ｆとを傾斜状をなすように形成し、さらに支持板２上面の左右側に、各窪み面１１ｅ，１１ｆのそれぞれの傾斜面が合わさってハの字状となるように並列に配置したものである。具体的には、前記のように並列に配置した２組の上向き窪み面１１ｅと下向き窪み面１１ｆの双方に、座板１の揺動静止位置から揺動最大位置に向かうに従い、緩やかに下降する勾配を設けている。これにより上向き窪み面１１ｅと下向き窪み面１１ｆとの間に介在した２つの球体６，６は、上向き窪み面１１ｅ及び下向き窪み面１１ｆの各傾斜面に沿って転がることになる。詳細には、一方の球体６が下り勾配の傾斜面に沿って転がれば、他方の球体６は登り勾配の傾斜面に沿って転がることで、座板１が山の頂上を越えるような動きで左右方向に揺動する。
尚、本実施形態では上向き窪み面１１ｅと下向き窪み面１１ｆとを傾斜状としたが、仮に上向き窪み面１１ｅのみに勾配をつけた場合でも、上向き窪み面１１ｅと下向き窪み面１１ｆとの双方を傾斜状とした場合と同様の作動を行える。 Further, in the first embodiment of the present invention, as shown in FIGS. 13, 14 (a), (b) and (c), the upwardly recessed surface 11 e and the downwardly recessed surface 11 f are formed so as to be inclined, and the support plate (2) The left and right sides of the upper surface are arranged in parallel so that the inclined surfaces of the recessed surfaces 11e and 11f are combined into a square shape. More specifically, the two sets of the upwardly depressed surface 11e and the downwardly recessed surface 11f arranged in parallel as described above gradually descend from the swinging stationary position of the seat plate 1 toward the maximum swinging position. A gradient is provided. As a result, the two spheres 6 and 6 interposed between the upward depression surface 11e and the downward depression surface 11f roll along the inclined surfaces of the upward depression surface 11e and the downward depression surface 11f. Specifically, if one sphere 6 rolls along a slope with a downward slope, the other sphere 6 rolls along a slope with an upward slope so that the seat plate 1 moves over the top of the mountain. Swings left and right.
In the present embodiment, the upward depression surface 11e and the downward depression surface 11f are inclined. However, even if only the upward depression surface 11e is inclined, both the upward depression surface 11e and the downward depression surface 11f are provided. The same operation as that of the inclined shape can be performed.

また本実施形態の拘束手段は図１５と図１６（ａ）（ｂ）のように、支持板２の上面に、左右に間隔をあけて２本の起立棒２５，２５をそれぞれ備え、さらに当該各起立棒２５，２５間にガイドレール３７を架設し、一方の座板１下面には、前記ガイドレール３７を介した前後に２枚の垂下板を備えており、さらに当該各垂下板間には、前記ガイドレール３７に沿って摺動可能な車輪３６を軸支している。これにより、座板１が支持板２上方への抜け出し、及び左右への離脱をすることなく、ガイドレール３７に沿って左右に摺動することとなる。従って、座板１と支持板２との間隔がほぼ一定に保たれることで、上向き窪み面１１ｅと下向き窪み面１１ｆとの間に介在する球体６の不意な離脱が防がれる。 Further, as shown in FIGS. 15 and 16 (a) and 16 (b), the restraining means of the present embodiment is provided with two upright rods 25, 25 on the upper surface of the support plate 2 with left and right spacings, respectively. A guide rail 37 is installed between the upright rods 25, 25, and two hanging plates are provided on the lower surface of one seat plate 1 on the front and back via the guide rail 37, and between the hanging plates. Supports a slidable wheel 36 along the guide rail 37. As a result, the seat plate 1 slides left and right along the guide rail 37 without being pulled out upward and left and right. Therefore, the interval between the seat plate 1 and the support plate 2 is kept substantially constant, thereby preventing an unexpected detachment of the sphere 6 interposed between the upwardly recessed surface 11e and the downwardly recessed surface 11f.

また図１７は、本発明の拘束手段の他の実施形態を示すものであり、この拘束手段は図１８のように、上向き窪み面１１ｅの底面と下向き窪み面１１ｆの天面とに、プレート状をなす磁石３８ａ，３８ｂをそれぞれ固着し、さらに球体６として金属製のものを適用した。そして各磁石３８ａ，３８ｂからの磁力によって前記球体６を吸着することで、上向き窪み面１１ｅと下向き窪み面１１ｆとの間で球体６の転がりを可能としながら、座板１と支持板２とを離脱不能とできる（第２実施形態）。さらに本発明の拘束手段は図１９のように、バネ材２６と扁平な樹脂ベルト２７とを組み合わせた形態のものでもよく、この形態の拘束手段の構成は具体的に、支持板２の左右側端縁に厚手のバネ材２６，２６をピン２９，２９によりそれぞれ固定し、さらに各バネ材２６，２６間に、肉厚の薄い樹脂ベルト２７を掛け渡すように結合し、この樹脂ベルト２７を支持板２側に備えた車輪２８に沿って摺動するように形成したものである。この形態の場合でも同様に、図２０（ａ）（ｂ）のように、座板１を支持板２から揺動機能部３を介して左右に揺らしながら、該座板１の支持板２からの離脱を同時に防ぐことができる（第３実施形態）。 FIG. 17 shows another embodiment of the restraining means of the present invention. As shown in FIG. 18, this restraining means has a plate shape on the bottom surface of the upwardly recessed surface 11e and the top surface of the downwardly recessed surface 11f. The magnets 38a and 38b forming the above are fixed, and the sphere 6 is made of metal. Then, by adsorbing the sphere 6 by the magnetic force from the magnets 38a and 38b, the sphere 6 can be rolled between the upwardly recessed surface 11e and the downwardly recessed surface 11f, and the seat plate 1 and the support plate 2 are connected. It can be made impossible to detach (second embodiment). Further, as shown in FIG. 19, the restraining means of the present invention may be in the form of a combination of a spring material 26 and a flat resin belt 27, and the configuration of the restraining means in this form is specifically the left and right sides of the support plate 2. Thick spring members 26, 26 are fixed to the end edges by pins 29, 29, respectively, and further, a thin resin belt 27 is joined between the spring members 26, 26 so that the resin belt 27 is It is formed so as to slide along the wheel 28 provided on the support plate 2 side. Similarly in the case of this embodiment, as shown in FIGS. 20 (a) and 20 (b), while the seat plate 1 is swung from the support plate 2 to the left and right via the swing function portion 3, from the support plate 2 of the seat plate 1. Can be prevented simultaneously (third embodiment).

図２１は本発明の第４実施形態として、座板１の揺動範囲を一定範囲内に規制する仕切部材を示したものである。この仕切部材は、起立片と横片とからなるL字材３０と、前記横片に設けたスリット３１と、該スリット３１内に差し込まれるボルト３２とからなっており、さらに該仕切部材は、上向き窪み面１１ｅと下向き窪み面１１ｆとにそれぞれ備えている。そして前記仕切部材の使用時は、まずボルト３２を緩め、Ｌ字材３０を上向き窪み面１１ｅ及び下向き窪み面１１ｆの適宜な位置にまでスリット３１に沿って左右移動させ、次いで、その位置で前記ボルト３２を締め付けることで、球体６の転がる範囲が、各Ｌ字材３０，３０の起立片と上向き窪み面１１ｅ及び下向き窪み面１１ｆとの囲まれた範囲内に設定され、これに伴って座板１の揺動範囲も小さくなる。 FIG. 21 shows a partition member for regulating the swing range of the seat plate 1 within a certain range as a fourth embodiment of the present invention. The partition member is composed of an L-shaped material 30 composed of a standing piece and a horizontal piece, a slit 31 provided in the horizontal piece, and a bolt 32 inserted into the slit 31. Each of the upwardly recessed surface 11e and the downwardly recessed surface 11f is provided. When the partition member is used, the bolt 32 is first loosened, and the L-shaped member 30 is moved left and right along the slit 31 to appropriate positions on the upwardly recessed surface 11e and the downwardly recessed surface 11f, and then at the position, By tightening the bolt 32, the rolling range of the sphere 6 is set within a range surrounded by the upright pieces of the L-shaped members 30, 30 and the upwardly recessed surface 11e and the downwardly recessed surface 11f. The swing range of the plate 1 is also reduced.

さらに本実施形態のストッパー３３は図２２のように、座板１の前側側面の中央位置に、左右の各保持金具に軸支され且つ上下方向に回動する掛金具３４を備えており、本座布団を使用する際に前記掛金具３４の先端側を持ち上げることで、支持板２側への掛止状態が解除される。また本座布団の使用を止める場合には、前記掛金具３４の先端側を下ろすような操作を行うことで、該掛金具３４の先端側が支持板２に設けた嵌凹部３５に嵌り込み、これにより座板１の左右への揺動を規制する。 Further, as shown in FIG. 22, the stopper 33 of the present embodiment is provided with a bracket 34 that is pivotally supported by the left and right holding brackets and pivots in the vertical direction at the center position of the front side surface of the seat plate 1. When the cushion is used, the state where the support plate 2 is hooked is released by lifting the tip side of the hook 34. When stopping the use of the main cushion, by performing an operation of lowering the front end side of the hanging bracket 34, the distal end side of the hanging bracket 34 is fitted into the fitting recess 35 provided in the support plate 2, thereby The swinging of the seat plate 1 to the left and right is restricted.
