A linear latch interconnecting a pivoting seatback with a frame location of a vehicle interior. The latch includes a bracket secured to a surface of the frame. An elongated gear rack exhibits upper and lower ratchet defining surfaces and is supported in linearly displaceable fashion to the bracket, a forward extending end of the gear rack connecting to the seatback such that the gear rack is biased in a first lineal direction relative to the bracket. A pair of locking members are pivotally secured to the bracket and are biased in first directions to engage selected teeth associated with the upper and lower ratchet defining surfaces of the gear rack. The locking members are concurrently pivoted out of contact with the gear rack to permit readjustment of the seatback in a second counter-biasing direction, following which they re-engage additional selected teeth associated with gear rack surfaces.
