本発明の実施例を図により説明すると、１は車両用シート１であり、座席シート２および背凭シート３を有する。該車両用シート１は、一人の着座者が着座する所謂キャプテンシートあるいは２人以上が着座するベンチシートの何れでもよい。
前記背凭シート３の側部には、側方からの衝突である側突されたとき、車両用シート１の着座者Ｔの横方向の移動を阻止または抑制するように作用する側突サポート機構Ｓを設ける。側突サポート機構Ｓは、前記背凭シート３の側部の一部により構成してもよく、どのように設けるかは任意である。 An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a vehicle seat 1 having a seat seat 2 and a backrest seat 3. The vehicle seat 1 may be a so-called captain seat on which one seated person sits or a bench seat on which two or more seats.
A side impact support mechanism that acts to prevent or suppress lateral movement of the seated person T of the vehicle seat 1 when the side seat of the back seat 3 is impacted from the side. S is provided. The side collision support mechanism S may be constituted by a part of the side portion of the dorsal seat 3 and how it is provided is arbitrary.

側突サポート機構Ｓは、車両用シート１の左右何れか一側または両側に設けるが、少なくとも、車両の扉を基準に扉と反対側の内側に設けると、シートベルトによる拘束が開放されたときでも、側突サポート機構Ｓにより着座者Ｔを支持できて、好適である。
側突サポート機構Ｓは、背凭シート３の骨格フレーム５の側部フレーム部６にステー７を固定する。ステー７には前後移動体８を前後方向に移動自在に取付ける。前後移動体８の取付構成は任意であるが、ステー７および前後移動体８の夫々には前後方向に長い挿通孔１０、１１を上下一対夫々形成し、挿通孔１０、１１の夫々にピンあるいはボルト等の係合部材１２、１３を挿通固定し、前後移動体８がステー７に対して挿通孔１０、１１と係合部材１２、１３により案内されて前後移動するようにする。 The side impact support mechanism S is provided on either the left or right side or both sides of the vehicle seat 1, but at least when the restraint by the seat belt is released if it is provided on the inner side opposite to the door with respect to the vehicle door. However, the seated person T can be supported by the side collision support mechanism S, which is preferable.
The side collision support mechanism S fixes the stay 7 to the side frame portion 6 of the skeleton frame 5 of the backrest seat 3. A longitudinally movable body 8 is attached to the stay 7 so as to be movable in the longitudinal direction. The front / rear moving body 8 can be mounted in any manner, but the stay 7 and the front / rear moving body 8 are each formed with a pair of upper and lower insertion holes 10, 11 in the front-rear direction, and a pin or a pin is inserted into each of the insertion holes 10, 11. The engaging members 12 and 13 such as bolts are inserted and fixed, and the longitudinal moving body 8 is guided by the insertion holes 10 and 11 and the engaging members 12 and 13 with respect to the stay 7 to move back and forth.

前記ステー７の裏側には駆動モータ１５を設け、駆動モータ１５の出力軸１６には駆動ギヤ１７を設ける。駆動ギヤ１７はステー７の窓孔部１８よりステー７の表側に突出させ、駆動ギヤ１７には前後移動体８に形成したラックギヤ１９を噛み合わせ、駆動ギヤ１７とラックギヤ１９の作用によって、ステー７に対して前後移動体８を前側移動させる。
前後移動体８の外周は樹脂カバー２０により包囲して、側突サポート機構Ｓのサポート部２５を形成する。サポート部２５は着座者Ｔを支持するために前方に移動すればよく、サポート部２５自体の構成は任意であり、前後移動体８の外周にクッション材を設け、その外周を表皮部材で被覆してもよい。 A drive motor 15 is provided on the back side of the stay 7, and a drive gear 17 is provided on the output shaft 16 of the drive motor 15. The drive gear 17 protrudes from the window hole 18 of the stay 7 to the front side of the stay 7, and the drive gear 17 meshes with a rack gear 19 formed on the front and rear moving body 8. The front-rear moving body 8 is moved to the front side.
The outer periphery of the front-rear moving body 8 is surrounded by the resin cover 20 to form the support portion 25 of the side collision support mechanism S.

しかして、車体の所望位置には側突予測用のレーダー装置Ｌを設け、レーダー装置Ｌと側突サポート機構Ｓの駆動モータ１５とは側突が予想されたとき、駆動モータ１５が作動してサポート部２５が前方に移動するように関連的に接続（連結）する。
２６はＶＳＣ（車両安定制御システム）、２７はＥＣＵ（制御ユニット）である。
また、サポート部２５は、座席シート２の座面から背凭シート３の上面の間の所定位置に位置すればよいが、実施例では車両用シート１の着座者Ｔの上腕部付近側方に設けると、側突時にシートベルトに拘束されにくい着座者Ｔの上半身をサポート部２５が支持できて好適である。 Thus, a side collision prediction radar device L is provided at a desired position of the vehicle body. When a side collision is expected between the radar device L and the drive motor 15 of the side collision support mechanism S, the drive motor 15 is activated. The support unit 25 is connected (coupled) in relation to move forward.
Reference numeral 26 denotes a VSC (vehicle stability control system), and 27 denotes an ECU (control unit).
Moreover, the support part 25 should just be located in the predetermined position between the seat surface of the seat 2 and the upper surface of the dorsal seat 3, but in the Example, it is in the vicinity of the upper arm of the seated person T of the vehicle seat 1. If provided, the support portion 25 can support the upper body of the seated person T which is not easily restrained by the seat belt at the time of a side collision, which is preferable.

また、上腕部付近側方にサポート部２５を位置させると、側突時に着座者Ｔの頭部がサポート部２５に衝突するのも避けられ、好適である。
また、背凭シート３の側面３０は、平面視において、後側に至るに従い内側に位置するように傾斜させ、この傾斜面により形成される空間に側突サポート機構Ｓのサポート部２５を位置させると、車両用シート１に着座者Ｔが着座したときに邪魔にならず、好適である。
また、背凭シート３の側面３０の所定位置に凹部３１を形成し、凹部３１内にサポート部２５を設けてもよい。 In addition, if the support portion 25 is positioned in the vicinity of the upper arm, it is preferable that the head of the seated person T collides with the support portion 25 during a side collision.
Further, the side surface 30 of the dorsal seat 3 is inclined so as to be located inward as it reaches the rear side in plan view, and the support portion 25 of the side collision support mechanism S is positioned in a space formed by this inclined surface. This is preferable because it does not get in the way when the seated person T sits on the vehicle seat 1.
Further, the recess 31 may be formed at a predetermined position on the side surface 30 of the dorsal fin sheet 3, and the support portion 25 may be provided in the recess 31.

（実施例の作用）
車両用シート１の背凭シート３の骨格フレーム５に固定したステー７に前後方向に移動自在に前後移動体８を取付けているから、車体の所望位置に設けた側突予測用のレーダー装置Ｌが側突を予測すると、駆動モータ１５を作動させ、駆動ギヤ１７とラックギヤ１９の作用によって、ステー７に対して前後移動体８を前側移動させ、これにより、サポート部２５が前方に移動する。
サポート部２５は、前側に移動すると、背凭シート３の前面より前側に突き出すので、車両用シート１の着座者Ｔの横方向の移動を阻止または抑制する。 (Operation of Example)
Since the front / rear moving body 8 is attached to the stay 7 fixed to the skeleton frame 5 of the back seat 3 of the vehicle seat 1 so as to be movable in the front / rear direction, the side collision prediction radar device L provided at a desired position of the vehicle body. If the side collision is predicted, the drive motor 15 is operated, and the action of the drive gear 17 and the rack gear 19 causes the front / rear moving body 8 to move forward with respect to the stay 7, whereby the support portion 25 moves forward.
When the support unit 25 moves to the front side, the support unit 25 protrudes to the front side from the front surface of the dorsal seat 3, and thus prevents or suppresses the lateral movement of the seated person T of the vehicle seat 1.

この場合、側突サポート機構Ｓは、着座者Ｔの状態の内側に移動するのを抑制するのに有効であるが、車両が横転したときでも、車両用シート１に対する横移動を阻止することで、シートベルトの肩ベルトの外れを防止でき、結果として、上下方向の移動も阻止または抑制する。
また、側突サポート機構Ｓは、車両用シート１の左右何れか一側または両側に設けるが、少なくとも、車両の扉を基準に扉と反対側の内側に設けると、シートベルトによる拘束が開放されたときでも、側突サポート機構Ｓにより着座者Ｔを支持できて、好適である。 In this case, the side collision support mechanism S is effective in suppressing the movement to the inside of the seated person T state, but even when the vehicle rolls over, it prevents the lateral movement with respect to the vehicle seat 1. Further, the seat belt can be prevented from coming off the shoulder belt, and as a result, the vertical movement is also prevented or suppressed.
In addition, the side collision support mechanism S is provided on either one or both sides of the vehicle seat 1, but if it is provided at least on the inner side opposite to the door with respect to the vehicle door, the restraint by the seat belt is released. Even if it is, the seated person T can be supported by the side collision support mechanism S, which is preferable.

また、車両用シート１の内側（反扉側）に側突サポート機構Ｓを設けた場合、例えば、図６は右側からの側突を示し、左側の着座者Ｔの内側移動を阻止するが、右側の着座者Ｔであっても「揺り戻し」といわれる反動による移動を阻止または抑制できる。   Moreover, when the side collision support mechanism S is provided inside the vehicle seat 1 (on the side opposite to the door), for example, FIG. 6 shows a side collision from the right side, and prevents the left occupant T from moving inward. Even the seated person T on the right side can prevent or suppress the movement caused by the reaction called “shake back”.
