Abstract
A seat belt system () has a control unit () and a seat belt () which includes a webbing () and a belt retractor (). The belt retractor () comprises a belt reel () for the webbing (), a rotation angle sensor () with a sensor unit and a rotatable measuring element, and a gear unit coupling the belt reel () to the measuring element. The belt reel () has a fully extended position and a ghost position. Furthermore, the gear unit is designed so that the gear unit reduces the rotation of the belt reel (), when the belt reel () is adjusted from the ghost position to the fully extended position, to a maximum of 1.0 revolutions of the measuring element. In addition, a method for determining the extension length of a webbing () of a seat belt system () wound on a rotatable belt reel () is provided.
