ABSTRACT:
A lock for an infant restraint used in a vehicle with a normally reclining shell in which a child is received. In a frontal crash the lock releases in the shell so that the shell and child pivot downwardly to a generally vertical position thereby greatly reducing the risk of injury and usually preventing injury of the child. To minimize the force required to release the lock, a roller bearing catch is engaged by a hook latch. The lock is normally latched and is released in a frontal crash by the inertia of a flyweight. To prevent the latch from being released during normal operation of the vehicle by forces produced by vibration, bumps and the like, preferably the flyweight and hook are connected by a lost motion coupling, a movable stop releasably engages the hook and the flyweight is yieldably biased toward the locked position.
