GASGENERATOR FOR ATSTRAMNINGSANORDNINGAR VID UPPLINDNINGSANORDNINGAR FOR SEKERHETSBELTEN

摘要

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.
