Safety belt system in a vehicle
First Claim
1. A safety belt system for a vehicle, which comprises a belt band means for encompassing a user and a tensioning means for tightening the belt band means against said user with an initial load precluding injury upon reaching a predetermined deceleration value, characterized in that the tensioning means includes a structural part being rotatable and at least partly surrounding the belt band means, said belt band means being freely movable through the structural part during normal operation.

Abstract
A safety belt system in a motor vehicle in which the belt band, when reaching a predetermined deceleration value, is tightened against the user with an initial load precluding injury by the use of a tensioning device actuated by an auxiliary force; the tensioning device is thereby constructed as a structural part which is adapted to be set into rotary movement and at least partly surrounds the belt band whereby the belt band runs through the structural part during normal operation in a substantially frictionless manner.

13. A safety belt system for a vehicle, which comprises a belt band means and a tensioning means for tightening the belt band means against a user with an initial load precluding injury upon reaching a predetermined deceleration value, characterized in that the tensioning means is constructed as a structural part operable to be set into rotary movement and at least partly surrounding the belt band means, and the belt band means running through the structural part during normal operation,
characterized in that the belt band means extends through a longitudinal slot of the structural part, said slot extending approximately in the direction of the axis of rotation, and characterized in that beginning with a predetermined tensional load acting on the structural part, the structural part is displaceable in the direction of the already tightened section of the belt band means.
