ABSTRACT:
A collision- or rapid deceleration-initiated stiffening system for a structural member of a motor vehicle frame. The system includes a structural member that defines a hollow, substantially gas-tight interior. The system also includes an inflator for pressurizing the interior of the structural member to increase the stiffness and the axial or buckle strength of the structural member upon collision or rapid deceleration of the motor vehicle. The inflator may produce inflation gas for pressurizing the structural member from different sources including the burning of solid pyrotechnic gas generant or the release of a stored gas, for example. In addition, the inflator may be initiated by different initiators including an electrical initiator squib connected to a remote deceleration sensor or a depressible initiator plunger in alignment with a bumper strut, for example. The inflator also may be used to inflate an airbag cushion of an airbag module in addition to pressurizing the structural member.
