Abstract
The invention relates to a belt retractor (10) with a switchable force limiter. Said belt retractor (10) comprises as the force limiter at least one energy absorbing element (13; 14, 15; 61) that is linked with the reel shaft (12) and with the locking device of the belt retractor (10) via a profiled bead (50). The belt retractor is further provided with a switch device with which the energy absorption is adjusted. The aim of the invention is to provide a switch device that functions independent of the transmission of power between the reel shaft and the torsion bar. Said switch device (latch 21) is designed in such a manner that it can be switched at any time during the already existing energy absorption via the drive (26) that is independent of the reel shaft (12) and/or the switch device.
