双方のロック機構１０，１１は、各作動軸に掛渡し固定する連結シャフト１２で一体に組み付けられている。操作レバー１３は、押下げ回転開錠用（図１の矢印）としてベルト装備側のロック機構１０に備え付けられている。その操作レバー１３は、ハウジング１０ａの軸受け穴１０ｃより外方に突出すると共に、シートクッション２のサイドブラケットより外方に突出する作動軸１０ｂの軸端側に取り付けられている。   Both the lock mechanisms 10 and 11 are integrally assembled by a connecting shaft 12 that is fixed to each operating shaft. The operation lever 13 is provided in the lock mechanism 10 on the belt equipment side for pressing and rotating unlocking (arrow in FIG. 1). The operating lever 13 protrudes outward from the bearing hole 10c of the housing 10a, and is attached to the shaft end side of the operating shaft 10b protruding outward from the side bracket of the seat cushion 2.

そのベルト装備側のロック機構１０には、作動軸１０ｂの軸線より立ち上がる突片１４を設け、突片１４の受け部１５をハウジング部１０ａの板面に設けたものが備え付けられている。このうち、突片１４としては作動軸１０ｂの軸線方向に亘る所定の長さを有し、作動軸１０ｂの円周方向に亘る所定の厚みを有するよう、上下の二つが作動軸１０ｂの軸線を介して相対位置に設けられている。   The lock mechanism 10 on the belt equipment side is provided with a protrusion 14 that rises from the axis of the operating shaft 10b, and a receiving portion 15 of the protrusion 14 provided on the plate surface of the housing portion 10a. Of these, the projecting piece 14 has a predetermined length in the axial direction of the operating shaft 10b, and the upper and lower two have the axis of the operating shaft 10b so as to have a predetermined thickness in the circumferential direction of the operating shaft 10b. Via a relative position.

突片１４の受け部１５は、図２で示すように作動軸１０ｂの突片１４と相応させてハウジング部１０ａの軸受け穴１０ｃより外回りに位置するよう上下に設けられている。その受け部１５は、図３で示すように作動軸１０ｂの突片１４と係合する当接縁１５ａを操作レバーの回転方向（矢印）に備え、一方、突片１４より離れて遊び間隔Ｇを保つ非当接縁１５ｂを操作レバーの非回転方向に備えるようハウジング部１０ａの板面に設けられている。   As shown in FIG. 2, the receiving portion 15 of the projecting piece 14 is provided up and down so as to correspond to the projecting piece 14 of the operating shaft 10b and to be located outward from the bearing hole 10c of the housing portion 10a. As shown in FIG. 3, the receiving portion 15 includes a contact edge 15 a that engages with the projecting piece 14 of the operating shaft 10 b in the rotation direction (arrow) of the operating lever, while being separated from the projecting piece 14 and having a play interval G. Is provided on the plate surface of the housing portion 10a so that the non-contact edge 15b is maintained in the non-rotating direction of the operation lever.

Further, the plate surface of the housing 10a may be provided by a concave portion protruding inward from the bearing hole 10c of the housing 10a.

このように構成するショルダーベルト付きの自動車用リクライニングシートでは、操作レバー１３（図１参照）を押下げ回転すると、作動軸１０ｂが図中時計方向の右回りに回転（図３参照）し、その回転が連結シャフト１２で双方のロック機構１０，１１に伝達され、各作動軸の同軸上に取り付けられたカムがロックギヤをカバープレートのギヤ歯から解除方向に変位させる。これにより、双方のロック機構１０，１１が開錠動し、シートバック１を前に倒し乃至は着座姿勢を角度調整できる。 In the automobile reclining seat with a shoulder belt configured as described above, when the operation lever 13 (see FIG. 1) is pushed down and rotated, the operating shaft 10b rotates clockwise in the figure (see FIG. 3). rotation is transmitted to both the locking mechanism 10, 11 by the connecting shaft 12, a cam mounted coaxially of each actuating shaft displaces in the release direction the lock gear from the gear teeth of the cover plate. Thereby, both lock mechanisms 10 and 11 are unlocked, and the seat back 1 is tilted forward or the seating posture can be adjusted in angle.

衝突等の衝撃により、万が一、シートバック１がベルト装備側のサイドフレーム１ａより前方に捩れ回転すると、ベルト装備側のロック機構１０において、図４で示すように受け部１５の非当接縁１５ｂが突片１４より離れた遊び間隔Ｇでベルト装備側のサイドフレーム１ａによる前方の捩れ回転を吸収し、作動軸１０ｂの突片１４と当接しない。これにより、連結シャフト１２が回転しないから、ベルト非装備側のロック機構１１を含む双方のロック機構１０，１１を施錠状態のままに保てる。   If the seat back 1 is twisted and rotated forward from the side frame 1a on the belt equipment side due to an impact such as a collision, the non-contact edge 15b of the receiving portion 15 in the lock mechanism 10 on the belt equipment side is shown in FIG. Absorbs the torsional rotation in the front by the side frame 1a on the belt equipment side at a play interval G away from the projecting piece 14, and does not contact the projecting piece 14 of the operating shaft 10b. Thereby, since the connection shaft 12 does not rotate, both the lock mechanisms 10 and 11 including the lock mechanism 11 on the belt non-equipment side can be kept in the locked state.

上述した実施の形態は、右ハンドル車のドライバー用シートに基づいて説明したが、右ハンドル車のアシスタント用シートにも同様に適用できる。アシスタント用シートの場合、操作レバーを車内アウター側（左サイド）に位置するロック機構の作動軸に備えると共に、シートバックの車内アウター側に位置する片肩部側に設けるアンカー部からシートクッションの車内インナー側（右サイド）となる側部後寄りとの間で着座者の上半身に斜掛けするショルダーベルトを備えればよい。   Although the above-described embodiment has been described based on a driver seat for a right-hand drive vehicle, it can be similarly applied to an assistant seat for a right-hand drive vehicle. In the case of an assistant seat, the operating lever is provided on the operating shaft of the locking mechanism located on the outer side (left side) in the vehicle, and the interior of the seat cushion from the anchor portion provided on the one shoulder side located on the outer side of the seat back in the vehicle. What is necessary is just to provide the shoulder belt which slants a seated person's upper body between the side part rear side used as an inner side (right side).
