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.

L'invention concerne un système de raidissement en cas de collision ou de décélération rapide pour un élément structural de véhicule automobile. Le système comprend un élément structural qui délimite un intérieur creux, essentiellement étanche aux gaz. Il comprend en outre un dispositif de gonflage permettant de mettre en pression l'intérieur de l'élément structural et d'accroître ainsi la rigidité ainsi que la résistance axiale ou la résistance à la déformation de l'élément structural en cas de collision ou de décélération rapide du véhicule. Le dispositif de gonflage peut produire un gaz servant à mettre en pression de l'élément structural et pouvant provenir de différentes sources (combustion d'un générateur de gaz pyrotechnique solide, dégagement d'un gaz stocké, par exemple). De plus, l'action du dispositif de gonflage peut être amorcée par un déclencheur pyrotechnique électrique raccordé à un capteur de décélération à distance ou par abaissement d'un piston en alignement avec une entretoise de pare-chocs, par exemple. Outre pressuriser l'élément structural, le dispositif de gonflage peut aussi servir à gonfler le coussin d'air d'un dispositif de protection pneumatique.
