Abstract: The invention relates to a motor vehicle seat comprising: a seat frame, a seat back, which is pivotally mounted on the seat frame, and which can be tilted forward toward a sitting surface of the seat frame; a longitudinal guide, with which the seat frame can be displaced in the longitudinal direction of the seat in order to adjust the longitudinal position of the seat; a detent device for locking the seat frame in a pre-adjusted longitudinal position of the seat; an actuating element for unlocking the detent device so that the seat frame can be displaced in the longitudinal direction of the seat; and, a coupling mechanism, which acts upon the actuating element and unlocks the detent device when the seat back is tilted forward the seating surface.
