Abstract: The invention relates to a belt retractor for a seat belt having a belt reel for winding up and unwinding the seat belt and a torsion bar which is arranged outside the belt reel and is connected at one bar end to a switchable fixing device. The switchable fixing device keeps the bar end rotationally fixed in one state and permits rotation of the bar end in another state. The switchable fixing device has a displaceable piston which, with a piston portion, in a locking position, can secure the bar end against rotation and, in a release position displaced in relation to the locking position, releases the bar end.
