ABSTRACT:
An inertial lock mechanism for limiting movement of a first object along a constrained path with respect to an adjacent second object. The mechanism includes a lock pin having a flat surface which is pivotally mountable to the first object and is biased toward a position in which the flat surface is parallel to the contrained path. A frame member mountable to the second object engages the flat surface so as to stop relative movement of the pin and rotate the pin against the biasing means at one end of the constrained path. A second stop surface on the frame member is sufficiently spaced apart from the angular surface to permit the biasing means to overcome inertia and pivot the lock pin out of engageable relationship with the second stop surface except when a predetermined amount of relative acceleration of the two objects occurs.
