<p>A cold gas inflator has an opening device (1) for rupturing a burst disk (17). The cold gas inflator is filled with stored gas. The cold gas inflator has a burst disk, which prevents the stored gas from exiting a pressure vessel (10). In the event of a automobile accident, the opening device is actuated, which causes the ignition of pyrotechnic material. This ignition generates a shockwave of sufficient energy to rupture the burst disk. The stored gas flows into the diffuser (21) and then exits the cold gas inflator in the radial direction. In another embodiment, the stored gas exits the cold gas inflator in the axial direction. <IMAGE></p> |
