A gas generator for a tightener in a safety-belt retractor comprises a cylindrical housing secured at one of its ends to a transition member between the housing of the retractor and a piston/cylinder drive of the tightener. At its other end the housing has a radial collar. The housing accommodates a propellant charge with a detonator. A hollow sleeve is inserted into the housing and has an outer diameter adapted to the inner diameter of the housing and an inner diameter adapted to a cylindrical capsule housing. The capsule housing has a bottom enclosing the propellant charge and is connected to a cylindrical base member which is inserted into the housing. The base member has a radial face bearing on the radial collar of the housing. The sleeve has a radially inwardly directed collar on the inner surface of which the bottom of the capsule housing bears.
A gas generator for a tightener in a safety-belt retractor, comprising a cylindrical housing which is secured at one of its two ends to a transition member between the housing of the safety-belt retractor and a piston/cylinder drive of the tightener and at its other end comprises a radial collar and accommodates in its interior a propellant charge with a detonator, a hollow cylindrical sleeve being inserted into a hollow cylindrical chamber formed inside of the housing, said sleeve having an outer diameter adapted to the inner diameter of said chamber and an inner diameter adapted to the outer diameter of a cylindrical capsule housing with a closed bottom which encloses the propellant charge and which is connected to a cylindrical base which is likewise inserted into said chamber of the housing, and which has a radial engagement face bearing on the radial collar of the housing, and the sleeve comprising a radially inwardly directed collar on the inner surface of which the bottom of the capsule housing bears.
