Abstract
Herein disclosed is a latch device for use with a foldable backrest of an automotive seat. The latch device comprises a striker secured to a fixed member other than the backrest; a base member secured to the backrest to move therewith; a latch plate pivotally supported by the base member, the latch plate being latchingly engageable with the striker when the backrest assumes a given raised position; a lock lever pivotally supported by the base member and having a portion contactable with a peripheral portion of the latch plate; biasing means for biasing the lock lever and the latch plate in the same direction; connecting means for selectively connecting the latch plate and the lock lever to achieve an integrated pivoting movement of the latch plate and the lock lever; and actuating means for actuating the connecting means, the actuating means including a projection which, upon operation of the actuating means, pushes the latch plate to rotate the same in a direction to cancel the latched engagement between the latch plate and the striker and at the same time to induce a folding of the foldable backrest.
