Patent ID: 7086625

Claim:
A belt retractor for a seat belt comprising: a belt reel; a retractor pawl which blocks the uncoiling of the seatbelt from the belt reel in the event of an accident; and a tightening device which tightens the seatbelt in a hazardous situation; wherein the tightening device includes a tightening pawl which, in a blocking position, blocks the belt reel in a belt uncoiling direction and, in a release position, leaves the belt reel unaffected; wherein the tightening pawl is assigned a sensor which monitors the position of the tightening pawl and transmits a signal specifying the position of the tightening pawl to a control device, and wherein the control device is configured so that when a signal is received from the sensor indicating that the tightening pawl has moved into the release position, the control device stops rotation of the belt reel in a tightening direction.
