ABSTRACT:
A collapsible arm rest for a passenger compartment of a motor vehicle comprises a flexible skin or covering, a layer of foam material underlying the flexible skin to provide a cushion and soft feel for the collapsible arm rest, a back plate for securing the collapsible arm rest to a generally vertical panel of a motor vehicle, and an insert embedded in the foam layer for strengthening the arm rest. The insert comprises a hollow bellows shaped thin walled shell that is attached to the back plate so that the shell collapses in the lateral direction when the arm rest is subjected to a side load of the type experienced in a side impact automobile collision. The shell defines an empty chamber that communicates with ambient air in the exterior environment of the arm rest via a small open vent and a large vent that is covered by a rupturable membrane that ruptures when the shell collapses in the lateral direction to avoid pneumatic delay in the lateral collapse of the shell.
