Device for introducing pressurized gas into a vehicle safety device

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, and
• the 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, and
• a trigger arrangement structured and arranged to be activated to cause retraction of the support device, and
• after 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,
• characterized in that the support device comprises a first support part and a back-pressure plate essentially forming a support part structured and arranged to be connected firmly with the first support part or is formed as a unit with the first support part, and
• a second support part that is structured and arranged to be connected with a chassis and on which the first support part is supported,
• the device being structured and arranged such that at least the first support part, in a mounted state prior to activation, extends perpendicular to the plane of the opening,
• the support device is structured and arranged to be destroyed by the first support part shifting parallel to the plane of the opening in relation to the second support part and opposite the second support part, there is a recess provided to accept the first support part after destruction of the support device.
