Abstract

The present invention relates to a belt retractor having a force limitation device (6, 7) with a two-part belt winding shaft (1) mounted between the legs (4, 5) of a U-shaped frame (2) so as to be rotatable about an axis of rotation, the belt-winding shaft having a first part (9) on which a belt strap can be wound, and a second part (10) which can be locked to the vehicle, relative to at least one of the legs (4, 5) of the frame (2), by means of an arresting device (8) that can be driven in a vehicle-sensitive and/or belt strap-sensitive manner, wherein the force limitation device (6) is formed by a first strap element (11, 12) which is arranged in the first annular chamber (15) and which, when the first and second parts (9, 10) of the belt shaft (1) move relative to each other, can be wound or unwound by running over a deflection point (24, 25) from an outer wall (22) of the first annular chamber (15) to an inner wall (23) or vice versa, thereby consuming energy, and wherein a second annular chamber (20) is provided between the two parts (9, 10) of the belt shaft (1), coaxially to the first annular chamber (15), and in which a second strap element (21) is deformed in an energy-consuming manner when the first and second parts (9, 10) of the belt shaft (1) move relative to each other.
