Abstract

Described is a gas generator unit comprising of a cylindrical gas generator (10), the lateral surface (10a) of which demonstrates emission holes (12) arranged in a thrust-neutral manner within a ring-shaped area (10b), and a deflector element (20), which is rigidly connected to the gas generator (10) and is made of a heat resistant material and at least surrounds the ring-shaped area (10b) at least partially. To make the gas generator harmless in the event of a fire, the deflector element (20) demonstrates, in an inflow area (20a) opposite the ring-shaped area (10b), borings (22), which are sealed by at least one blocking element (24, 32) made of a meltable or combustible material, the borings being arranged in such a manner that the gas generator unit is thrust-neutral in the absence of the blocking element (24).
