Abstract
Abstract A redirecting device for a safety belt for use in motor vehicles, in which one end is rolled up on an automatic winder and the other end of the safety belt has a fitting for connecting the belt to a lock. The redirecting member is a hollow rotatable cylindrical member, wider than the belt, mounted on an axle supported by the legs of a bracket. Roll elements are disposed at the ends of the rotatable member to support it and permit it to rotate freely. Additional roll elements which project beyond both sides of the wall of the rotatable member are disposed in the central region of the rotatable member. This has the advantage of a smaller ratio of retraction force to pull-out force of the belt.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
A redirecting device for a safety belt in which one end of the safety belt is rolled up on an automatic winder in an end region and the other end of the safety belt has a fitting for connecting the belt to a lock, a redirecting member supported in the redirecting device, over which member the belt passing in contact with the redirecting member is led in the redirection region, the redirecting member comprising in the contact zone of the belt a rotatable member having a wall as the outer surface around which the belt is partially looped, with the rotatable member of width greater than the width of the belt to extend beyond the belt on both sides, and roll elements supporting the rotatable member to permit the rotatable member to rotate freely, and wherein additional roll elements are disposed in the central region of the rotatable member which project beyond the wall of the rotatable member on both sides of the wall.
Claim 2
Dependent Claim
