Abstract
A motion restriction device is provided for selectively preventing movement of a structural member. The motion restriction device includes a container abutting against the structural member. The container is at least partially filled with a velocity-dependent material that transitions between a fluid-like state when the structural member moves at a velocity below a predetermined threshold to permit movement thereof and a solid-like state when the structural member moves at a velocity above a predetermined threshold to block movement thereof.
