ABSTRACT:
A passenger car seat back inertia latch providing gravity actuated latch release and deceleration responsive inertia latch retention characterized by a compound resolution of predominant opposing gravity and deceleration forces to provide more sensitive and dependable latch retention at a predetermined minimum emergency vehicle deceleration as well as minimum weight to unlock the latch when the vehicle is stationary over a wider range of seat back adjustment and vehicle inclination than is possible with the conventional simple one-piece inertia latch wherein horizontal and vertical coordinates of the center of gravity relative to a latch pivot are solely depended upon to produce respective opposite gravity actuated release and inertia actuated locking moments on the latch element.
