Abstract:
Device to allow pressurized gas into a vehicle safety device, comprising a pressurized container for compressed gas with at least one opening sealed with a gas-tight film covering,the film covering being supported, over at least a large portion of a free surface thereof, in a plane of the opening by a support device that is structured and arranged to be retractable in a direction perpendicular to the plane of the opening,the support device being supported, in turn, on the pressurized container, andthe support device being structured and arranged such that the compressed gas produces a force through the film covering perpendicular to the plane of the opening and directed outwardly to act on the support device,this force being in equilibrium with a force of reaction of the retractable support device prior to activation, anda trigger arrangement structured and arranged to be activated to cause retraction of the support device, andafter activation of the trigger arrangement, the support device is structured and arranged to first move a short distance relative to a diameter of the opening, in a direction parallel to the plane of the opening and then move freely over a longer distance in a direction perpendicular to the plane of the opening.
