摘要： Herein disclosed is a powered seat slide device which comprises a threaded shaft which is neatly received in an elongate tunnel-like space defined between coupled movable and stationary rails and rotatably held by the movable rail, a nut which is received in the tunnel-like space to be operatively engaged with the threaded shaft and connected to the stationary rail. One end of the threaded shaft is projected from the tunnel like-space to form an exposed end. A gear mechanism incorporated with the exposed end of the threaded shaft for transmitting a power of an electric motor to the threaded shaft is arranged outside of the coupled rail unit.

摘要： A vehicle front seat of the kind capable of being selectively rotated into a forward position or rearward position has a turntable unit or rotation adjusting mechanism provided between the seat and a vehicle floor. The rotation adjusting mechanism includes a stationary circular guide and a rotating disk disposed inside the stationary guide. The rotating disk is provided with a latching arm having an engagement tooth. The stationary guide has a locking through hole for engagement with the engagement tooth of the latching arm. A cam is disposed inside the locking through hole and capable of contacting the engagement tooth inserted into the locking through hole. The cam is rotatable in response to movement of the engagement tooth. An amount of rotation of the cam is detected by a microswitch. The cam is provided with first and second circular arc cam surfaces and capable of absorbing possible errors in attached positions of the constituent parts of the rotation adjusting mechanism.
摘要翻译：能够选择性地旋转到前进位置或后方位置的车辆前座具有设置在座椅和车辆地板之间的转台单元或旋转调节机构。旋转调节机构包括固定的圆形引导件和设置在固定引导件内部的旋转盘。旋转盘设置有具有接合齿的闭锁臂。固定引导件具有用于与锁定臂的接合齿接合的锁定通孔。凸轮设置在锁定通孔内部并且能够接合插入到锁定通孔中的接合齿。凸轮能够响应啮合齿的移动而旋转。通过微动开关检测凸轮的旋转量。凸轮设置有第一和第二圆弧凸轮表面，并且能够吸收旋转调节机构的构成部件的附接位置的可能误差。

摘要： An automotive folding seat is adapted to be retracted to provide a wider entrance space for passengers. The seat back can be folded onto a seat cushion and the seat in its entirety can be pivoted to a retracted position wherein the seat cushion is aligned vertically with the seat back folded onto the seat cushion. A locking mechanism serves to hold the seat cushion in its normal operating position. The locking mechanism is engageable to a striker rigidly mounted on the vehicle body and associated with a hinge mechanism which latches the seat back in its normal operating position and allows pivotal movement to the folded position in response to release operation of an operation lever. The operation lever also causes the locking mechanism to release its locking engagement with the striker to allow retracting movement of the seat cushion. The locking mechanism and the striker are adapted to ensure mutual locking engagement by restricting their relative displacement to even when a significant bending stress is applied to the seat.
摘要翻译：汽车折叠座适于缩回以为乘客提供更宽的入口空间。座椅靠背可以折叠到座垫上，并且座椅整体可以枢转到缩回位置，其中座垫垂直地对准座椅靠背折叠到座垫上。锁定机构用于将座垫保持在其正常操作位置。锁定机构可接合到刚性地安装在车体上的撞针并与铰链机构相关联，该铰链机构将座椅靠背锁定在其正常操作位置，并且响应于操作杆的释放操作允许枢转运动到折叠位置。操作杆还使得锁定机构释放其与撞针的锁定接合，以允许座垫的缩回运动。锁定机构和撞针适于通过限制它们的相对位移来确保相互锁定接合，即使当对座椅施加显着的弯曲应力时。

摘要： A vehicular seat is formed with an adjustable spring structure at an internal portion thereof. The structure is selectively adjustable for determining the degree of support the seat occupant receives at his or her lower back and features an arrangement which is supported on the end of a pair of adjustable crank arms so as to be operable between a normal position in which the support to the lower back of the seat occupant is mildly enhanced, and an extra support position in which the seat back contour is altered and the support of the seat occupant's lower back is greatly enhanced in a manner which reduces fatigue of the seat occupant over long periods.
摘要翻译：车辆座椅在其内部形成有可调节的弹簧结构。该结构可选择性地调节，以确定座椅乘客在他或她的下背部接收的支撑程度，并且具有支撑在一对可调节曲柄臂的端部上的装置，以便在正常位置之间操作，对座椅乘客的下背部的支撑轻度增强，并且以更小的方式大大增强了座椅后轮廓改变的座椅靠背轮廓和座椅乘客的后背的支撑的额外支撑位置，以减少座椅乘客长时间的疲劳时期。
