An air bag apparatus with a destructible connecting section between a gas generator and a non-metallic gas lance

摘要

An air bag apparatus with a gas generator (1) on the one end of a diffuser (2) with radial outflow openings (3) is arranged, and on which a connecting portion (19) is formed, on which a non-metallic gas lance (6, 15) with a coaxial receiving of the diffuser (2) upstream of the same is fastened, the non-metallic gas lance (6, 15) at its the connecting section (19) associated axial end by means of a reinforcing means (5, 18), or is placed on such a, which on the one hand, in the normal operation of the gas generator (1) the gas stream (4) of the diffuser (3) of the radial outlet flow direction deflects into an axial outlet flow direction as well as an effective thermal amplification of the gas lance (6, 15) in this connecting section (19), and, on the other hand, in the case of a strong thermal action (8) from the outside on these connecting portion (19) as well as an unwanted self-ignition of the gas generator (1) to a destruction of the gas lances material together with the reinforcing means (5, 18), as a result of which the deflection of the gas stream (4) of the radial in..
