AI Technical Summary

Problems solved by technology

Simultaneous pivoting of the deflection element may be disadvantageous in the event of a traffic accident, since the seat belt may jam or become entangled on the deflection element when a critical pivot angle is reached
As a result, the function of the seat belt will be impaired

Embodiment Construction

[0011] FIG. 1 shows a seat belt arrangement with a seat belt 1 for a vehicle occupant 2 . The belt 1 is rolled up by the belt end 11 on the belt roller 3 . The belt roller 3 is connected to the vehicle body 8 in the bottom region 81 of the vehicle body 8 . The seat belt roller 3 has a torsion generating device, which can exert a preload in the direction of rolling up the seat belt to tighten the seat belt 1 . In addition, the belt roller 3 has a deployment blocking device, which prevents the seat belt 1 from resisting the force on the torsion generating device in the event of rapid elongation of the seat belt 1 and / or acceleration of the deployment of the seat belt due to an accident.

[0012] The seat belt 1 extends from the end 11 connected to the belt roller 3 through a belt deflection device 4 to a belt buckle 5 where the other end 12 of the seat belt is releasably secured or keep.

[0013] The belt deflection device 4 has a one-piece holding body 41 which is rigidly fa...

Abstract

A seat belt-deflecting device which has a simple and cost-effective construction. The deflecting device includes at least one holding body on which a deflecting element is held. The seat belt is deflected about the deflecting axis of the deflecting element. The deflecting device also includes a belt-deflecting edge which is formed by the shaping of the holding body and about which the seat belt of the motor vehicle is additionally deflected in the direction of the vehicle occupant. The deflecting axis of the deflecting element and the deflecting edge forming an acute angle with respect to each other.

Description

technical field [0001] The invention relates to a device for a seat belt. Background technique [0002] German patent application DE 101 03 319 A1 (hereby incorporated by reference) describes a seat belt deflector with an energy absorbing unit. In the event of a traffic accident, the vehicle occupant deflects the seat belt, applying an appropriate tension on the deflection device. In order to limit the restraint forces acting on the vehicle occupants, in the case of the aforementioned known belt deflectors, the energy absorbing unit is configured such that the seat belt is allowed to bend; the deflection elements of the belt deflector are shifted or moved, and The deflection element is held by the holding body, resulting in a "stretch of the seat belt" for the vehicle occupant. In order to enable the described energy absorption, the aforementioned known belt deflectors are of multi-part construction. [0003] US Patent No. 5,139,282 (incorporated herein by reference) desc...
