Abstract: An automobile seat comprising a seat bottom rotatable around a transverse axis approximately parallel to a car body floor, a seat back inclinably mounted on the seat bottom, a seat bottom lock for releasably locking the seat bottom to the floor, a seat back lock for releasably locking the seat back to the seat bottom, and a link for interlocking these locks in such a manner that, when one of them is released, the other is automatically released. The seat bottom lock is provided with a striker fixed to the floor and a lock piece mounted on the seat bottom for engagement with the striker and the seat back lock is provided with a hook for locking the rotation of the seat back. The link transmits the movement of either the lock piece or the hook to the other. In a reclining seat, the seat back lock is formed to releasably lock a knuckle bracket of the reclining mechanism to the seat back or the seat bottom.

Abstract: An automobile seat comprising a seat bottom rotatable around a transverse axis approximately parallel to a car body floor, a seat back mounted on the seat bottom and capable of being inclined forwards, a seat bottom lock for releasably locking the seat bottom to the floor, a seat back lock for releasably locking the seat back to the seat bottom, and a lock releasing and linking mechanism for linking the forward inclination of the seat back and the rotation of the seat bottom to each other so as to conduct both seat back forward inclination and seat bottom rotation by a single operation. The lock releasing and linking mechanism is provided with an actuation piece for detecting the rotation of the seat bottom and a drive member for releasing the seat back lock by the actuation of the actuation member. Or, the mechanism is provided with an interlocking member for releasing the seat bottom lock in a manner interlocked with the forward inclination of the seat back.

Abstract: A seat back framework of one-piece construction together with a head rest support is made from a single blank of fiber-reinforced plastics. The seat back framework comprises a generally rectangular body having opposite upper and lower walls, a pair of opposite side walls and a connecting wall extending between the side walls in spaced relation to the upper wall with a support space defined therebetween. A pair of guide members for axially adjustably supporting corresponding legs forming a part of the head rest assembly together with a head rest are formed on the rectangular body within the support space.

Abstract: A reclining arrangement for a seat or the like including a seat back reclinably mounted to a seat cushion through a reclining knuckle having a rough adjusting mechanism for roughly adjusting, stepwise, the folding angle of said seat back with respect to said seat cushion. The reclining arrangement includes a first arm of the reclining knuckle selectively fixed to either one of the seat back or seat cushion, a second arm of the reclining knuckle pivotally connected to the remaining one of the seat back or seat cushion, and a fine adjusting mechanism so provided as to adjust the angle of rotation of the second arm, the rough adjusting mechanism being disposed to be spaced a predetermined distance from the fine adjusting mechanism.

Abstract: A front seat includes a seat cushion and a reclining back cushion, and is so arranged as to move back and forth between forward and retracted positions. The seat is temporarily released from the latched position for moving the seat towards the most forward position for facilitating movement of the rear seat passengers into and out of the vehicle. Thereafter, the front seat is again returned and latched in an original position by the operation of latch releasing mechanism employed in the front seat.
