Abstract
The principles of seatbelts for the VW-vehicles with a retractor which is sensitive to vehicle deceleration and to webbing acceleration is described. In addition possibilities are shown to reduce the Severity Index with energy absorbing devices in the seat belt retractor or in the B-pillar-ring. The results show that the requirements from the NHTSA up to Notice No. 16 of Docket 69-7 cannot be fulfilled in relation to the Severity Index (SI).
