Abstract
A belt retractor for a seatbelt comprising a retractor pawl which blocks the seatbelt from being pulled out of the belt retractor in the event of an accident, and having a tightening device which tightens the seatbelt in a hazardous situation, the tightening device includes a tightening pawl which, in a blocking position, blocks the belt retractor in the belt uncoiling direction and, in a release position, leaves the belt retractor unaffected. The tightening pawl is assigned a sensor which monitors the position of the tightening pawl and transmits a signal indicating the position of the tightening pawl to a control device of the tightening device.
