Disclosed herein is a latch device for use in 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 member pivotally supported by the base member, the latch member being latchingly engageable with the striker when the backrest assumes a given raised position; biasing means for biasing the latch member in a direction to achieve a latched engagement between the latch member and the striker; a latch cancelling mechanism connected to the latch member for pivoting the latch member in a direction to release the striker when moved in a given direction; a one-way mechanism interposed between the latch cancelling mechanism and the latch member, the one way mechanism permitting only a transmission of movement from the latch cancelling mechanism to the latch member; and a stopper mechanism including a lever moved with the latch cancelling mechanism and stopper rod which is projectable into a position to interrupt the movement of the lever.
