    • A reclining angle adjustment device for a seat includes a shaft having a concentric portion and an eccentric portion and rotatable for adjusting the reclining angle of the seat, a tapered bushing having a tapered inner peripheral surface engaging the eccentric portion along the shaft, a gear train including an external gear and an internal gear meshing with the internal gear, the internal gear having more teeth than the external gear, a first arm having one of the external and internal gears which is rotatably fitted at its center over the concentric portion, and a second arm having the other gear which is rotatably fitted at its center over the tapered bushing. A resilient member normally presses the tapered bushing axially of the shaft in a direction to strengthen meshing engagement between the external and internal gears.

    • An apparatus for positioning the backrest of a vehicle seat to facilitate an occupant's entry and exit from the vehicle. The apparatus includes a seat frame mounted on the floor of a vehicle and a backrest frame pivotally connected to the seat frame. A pawl member releasably engages the seat frame from teeth on the backrest frame and is controlled by an operating lever to adjust the pivotable position of the backrest. A support member slidably positions the seat frame along the vehicle and includes a pair of spaced lower rails and a pair of complimentary upper rails slidably mounted on the lower rails. A locking device mounted on the upper rail prevents sliding movement between the upper and lower rails. A cable means extending between the backrest and the locking device releases the locking device to enable sliding movement between the upper and lower rails when the backrest is pivoted beyond a predetermined position. The backrest, which is biased toward the front of the vehicle, cannot be pivoted back to its original position until a positioning lever engages a cam surface mounted on the lower rail to disengage a restricting arm engaged within a groove on the backrest.
    • 一种用于定位车辆座椅靠背的装置,以便于乘客从车辆进出。 该装置包括安装在车辆的地板上的座椅框架和可枢转地连接到座椅框架的靠背框架。 棘爪构件可释放地将座椅框架与靠背框架上的齿接合,并由操作杆控制,以调整靠背的可枢转位置。 支撑构件沿着车辆可滑动地定位座椅框架,并且包括一对间隔开的下轨道和一对可滑动地安装在下轨道上的互补上轨道。 安装在上部导轨上的锁定装置防止上部和下部导轨之间的滑动。 在靠背和锁定装置之间延伸的电缆装置释放锁定装置,以便当靠背枢转超过预定位置时能够在上轨道和下轨道之间滑动。 朝向车辆前方偏置的靠背不能枢转回到其原始位置,直到定位杆接合安装在下轨道上的凸轮表面以脱离接合在靠背上的凹槽内的限制臂。
