GAS GENERATOR AND MANUFACTURING PROCESS THEREOF

摘要

The invention relates to a gas generator (1), including an initiator (7) having a case (9), two electrodes (5, 6) and a cap (8) having a wall (82) delimiting an aperture (83) for insertion of the case (9), a part (2) delimiting an aperture (4) for access to the electrodes (5, 6) and a retaining part (10) made of plastic material overmoulded into the aperture (4) between the initator (7), the cap (8) and the part (2). According to the invention, the wall (82) includes, near the aperture (83) and the protrusion (84) retaining the cap (8), a second protrusion (86) for supporting the mould in a support direction (F) having a component (A) extending from the bottom (81) toward the aperture (83), the second protrusion (86) having an outer edge (862) at least partially not covered by the part (10) for use as a support surface in said support direction (F) for a mould to be used for overmoulding.
