Abstract
A seat belt retractor with a load limiting device and a tensioning device includes a two-part belt shaft with a first part (1), upon which the belt can be wound, and a second part (5), which can be locked in a vehicle-fixed manner in a frame (8) of the seat belt retractor. A tensioner drive wheel (6) for driving the seat belt retractor in the winding direction is located between the first (1) and the second part (5) of the belt shaft on a hollow cylindrical appendix (5a) of the second part (5) of the belt shaft, and the load limiting device (3) extends into the ring cylindrical appendix (5a) of the second part (5).
Claims7
A seat belt retractor with a load limiting device and a tensioning device including a two-part belt shaft with a first part configured for winding the belt on the first part, and a second part configured to be locked in a vehicle-fixed manner in a frame of the seat belt retractor, a tensioner drive wheel for driving the seat belt retractor in a direction corresponding to winding the belt onto the first part, the tensioner drive wheel being located between the first part and the second part of the belt shaft on a hollow cylindrical appendix of the second part of the belt shaft, and the load limiting device extending into the hollow cylindrical appendix of the second part.
