Abstract: A seat reclining apparatus includes a folding operation lever displacing a reclining lock mechanism to a lock release position. When the folding operation lever is operated to a folding operation position, the reclining lock mechanism is displaced from a lock position to the lock release position. A seatback is displaced to a folded position by a biasing force of a folding biasing unit. A neutral position returning unit that retains a releasing lever disposed between the folding operation lever and the reclining lock mechanism when the seatback is inclined forward beyond a predetermined neutral position, and does not retain the releasing lever when the seatback is inclined rearward beyond the neutral position is further provided. A configuration for returning the seatback to the neutral position can be provided by a simple structure and only a slight design change at a lower production cost, and assembling is performed simply.

Abstract: A vehicle seat having a folding mechanism is comprised of a locking mechanism allowing or preventing seat sliding, a wire joined to the locking mechanism, unlocking or locking the locking mechanism when pulled or at rest respectively, a base member disposed above the locking mechanism, a first actuating member, rotatably supported on the base member, a second actuating member, rotatably supported on the base member coaxially with the first actuating member and joined to another end of the wire, allowing the wire to be at rest when in a forward position and pulling the wire when rotated by the first actuating member to a backward position when the first actuating member is rotated backward, an upper member rotatably supported on the base member, and an engaging projection member which is contactable with the first actuating member to rotate the first actuating member backward or forward.
