Abstract
Herein disclosed is a latch device for latching an inclinable bark rest cushion to a seatback of a seat when the cushion is snugly received in a tunnel formed in the seatback. The latch device comprises a striker secured to the seatback, a latch member pivotally mounted in the cushion, a spring incorporated with the latch member to bias the same in a direction to achieve a latched engagement between the latch member and the striker, an actuation member pivotally mounted in the cushion in a manner to push and pivot the latch member in a releasing direction to cancel the latched engagement between the latch member and the striker when pivoted in a given direction, means having a pin portion which is projectable into a travelling way of the actuation member thereby to interrupt the actuation member from pivoting in the releasing direction, a base member secured to a rigid portion of the cushion and having an opening through which the pin portion passes, and a mechanism for manually actuating the pin portion from a back side of the back rest cushion.
