Abstract
Described is a belt tensioner for a seat belt having a belt retractor, a tensioner pinion () non-rotatably connected to the belt retractor, a tube () having a pyrotechnical gas generator arranged therein, and a plurality of mass bodies () driven by the pressure generated by the gas generator. The mass bodies () engage with the tensioner pinion () in a force transmitting manner and drive the belt retractor in the winding direction. A first and a second section () of the tube () run parallel to each other. A third section () with a curved course that projects out of the plane (E) connects the first and second sections, thereby creating a space () between the first, second and third sections (), for accommodating at least one of the mass bodies ().
