Retightener with a pyrotechnic propellant charge for automatic safety-belt wind-up devices having an energy converter, wherein in the event of danger the explosive pressure of the ignited propellant charge acts on a pullout element tightening the safety belt around the body of the vehicle passenger to be protected via a liquid buffer arranged between the propellant charge and a pull-back element. In accordance with the invention a turbine housing is disposed around the turbine wheel with a hollow space on one side between the turbine wheel and the wall of the housing to form a turbine pressure chamber. A receptacle containing liquid medium has its outlet opening into the turbine pressure vessel. The outlet of the receptacle is aligned substantially tangentially to the turbine wheel. |
