Document Type and Number:
Japanese Patent JP2509371
Kind Code:
B2
Abstract:
The invention relates to a cold-gas pyrotechnic generator, in particular intended for automobile safety, as well as a method for manufacturing this generator. The generator according to the invention comprises a casing (2) of revolution consisting of a base (10) and a cover (20) establishing: a central channel (80) in which an ignition device is placed, an annular intermediate chamber (70) containing elements (40) of a gas-generating pyrotechnic composition, a peripheral annular chamber (60) containing a filter. A continuous lateral opening (71) is provided between the central channel (80) and the intermediate chamber (70). The method for manufacturing a generator of this type consists in assembling the cover (20) with the base (10) containing the filter by friction welding, in placing the casing (2) thus formed onto a lathe and in introducing, after setting in rotation, the pyrotechnic elements (40) into the chamber (70) through the opening (71) and, lastly, in installing the ignition device. The invention thus enables the welding of the casing of the generator to be carried out in the absence of any pyrotechnic element.
