Abstract:
A belt tensioner, for use as a buckle tensioner for a vehicle occupant restraint system, comprising a housing (3, 5) having a cylindrical housing wall, a gas generator, a working space (15) which is defined in the radial direction by the housing wall and into which the pressurized gas released in a restraint situation flows, a piston part (9) which is displaceable in the working space (15) by the pressurized gas, a belt engagement means in force-transmitting relationship with the buckled belt, and a traction transfer means (7) which connects the belt engagement means with the piston part (9), a housing-fixed deflection means for deflecting the stream of pressurized gas being provided in the working space (15), characterized in that the deflection means is adapted to guide the stream of pressurized gas radially obliquely outwards away from the traction transfer means (7) and towards the housing wall, in this way preventing the pressurized gas which flows out of the gas generator from directly impinging on the traction transfer means (7).
