The latch device comprises a striker fixed to the seatback, a stationary base member fixed to the seatback, a spring-biased latch member pivotally connected to the base member and latchingly engageable with the striker, a pull strap fixed to the latch member and exposed to the passenger room to be manipulated from the passenger room, a movable base member movably mounted on the stationary base member, a lock member pivotally mounted on the movable base member and movable to a position to obstruct the pivoting movement of the latch member in the striker releasing direction, a lock member actuating member pivotally mounted on the movable base member and engageable, when pushed by the striker, with the lock member to move the same away from the travelling path of the latch member, a lock cancelling member movably mounted on the movable base member and moving the latch member in the striker releasing direction when moved in a given direction by a given distance, and a structure connected to the movable base member to move therewith. The structure has a manually controlled lever which is projected outward from a slot formed in a back portion of the back rest cushion to be operable from a trunk room of the vehicle.
