Abstract
A belt retractor with a belt spool rotatably mounted in a frame comprises an integrated force limiter, which has a metal band with a first end connected to the belt spool, and a control part rotatably mounted relative to the belt spool, said control part being able to be locked stationary on the frame by a locking mechanism, said metal band having a second end connected to said control part, said metal band being led through a baffle which is fixed to said control part, and on exceeding of a determined traction force in the belt webbing, said metal band is pulled through said baffle and is thereby plastically deformed. To make the level of the traction force adjustable, on the exceeding of which the deformation of the metal band occurs and hence the force limitation becomes effective, the baffle member has at least one selectively adjustable deflection element the relative position of which with respect to directions in which said metal band extends, defines a level of traction force where said band is pulled through said baffle.
