Abstract
A belt strap (1) for safety belts which is to have outer surfaces of as low friction as possible so that it can run through the safety belt system with as little friction as possible. The warp threads (3), which are woven into the belt strap, have filaments (5) of at least 15 dtex, particularly 17 dtex. The warp threads (3) are, in one embodiment, untwined and tangled at certain points with compressed air, whereby the tangled points (7) can be spaced from one another by 5 to 15 cm. In another embodiment the warp threads are twined only slightly, namely with 30 to 50 twists per meter thread length.
Claims4
