Abstract
An inertia sensitive latch assembly particularly adapted for preventing forward dumping of a motor vehicle seat back. The embodiments are particularly suited for applications in station wagon vehicles having forward dumping capability of the second passenger seats. The device is enclosed within the seat back and includes a pendulum engageable with a latch hook affixed to a support structure. The pendulum engages the hook when the vehicle is subjected to deceleration loads above a predetermined level. In one embodiment of the invention, a retention clip device is provided which maintains the pendulum engaged with the latch hook after a deceleration load is relieved to maintain the seat in engagement throughout multiple impact vehicle conditions. Both embodiments are substantially enclosed within the seat back cushion structure, thus protecting them and providing an unobstructed load floor when the seat back is dumped forward.
