A belt strap has now been found which has the desired " Requirements, so less thickness than the known belts made of 2 or multi-layer fabric without reducing the Strength and safety properties of these straps Fulfills. The belt strap according to the invention consists of a A fabric composed of synthetic warp and weft threads, which is characterized in that dip warp threads are made from multifilaments synethebischoi} linear polyamide, polyacrylonitrile or polyester material and the weft threads are monofilaments made of synthetic linear polyester material.

It is advantageous to remove both the warp and the weft threads of synthetic linear polyester material, preferably of polyethylene terephthalate. Of course Any of the usual thread-forming polyesters and copolyesters, e.g. poly-

1 , ii-cyclohexanedimethanol terephthalate and the copolyester of terephthalic acid / isophthalic acid and ethylene glycol can be used. As synthetic linear polyamide material for the nmltifilen warp thread mainly polyairide 6 and polyamide 6 come into question, but of course all other thread-forming polyamides and copolyamides can also be used; can be used.

The thickness of the warp and weft threads in the inventive Webbing should meet the respective strength and safety requirements adapted rope .. -Preferably the thickness of the monofilament weft threads is 0.1.5 to 0.1 mm.

It should also be mentioned that the multifilament warp threads in the belt

The strap according to the invention is especially advantageous "- ■■" properties, constructed from multifilament warp and from mono- _ '-filament weft yarns tissue -if a Thermofixierprozess in a temperature range of about 200 to 230 ⁰ C ₅ preferably for at least 2 minutes, subjected to became. In such a belt webbing, the monofilament transverse threads easily break open in the longitudinal direction when subjected to heavy loads, so that the warp threads are no longer held in the fabric and protrude from the fabric surface. This makes it possible to immediately and easily identify heavy loads on the belt straps, e.g. the load on a car seat belt in the event of an accident. This is very important because it is known that belt straps stretch to the point of their breaking load under high loads, whereby the straps then become practically unusable as a result of the loss of their work capacity. The previously customary webbing mandrel made of fabrics made from multifilament warp and weft threads could not be seen from the outside when the load had exceeded a critical point for safety. The check whether the previously known belts already exposed to a high load Trartren, ordered in by incorporation of observing the behavior of the straps in a repeated heavy load. If the belts have not previously been exposed to heavy loads, they will then become unusable as a result of the test load. This disadvantage is remedied by the belt strap according to the invention in the described preferred Ausfixhrxaigsforin, nänilich snit thernofixierteri fabric, since this strap immediately sees a load beyond the critical point externally. The breaking of the thermoset monofilament transverse threads at high longitudinal loads of the erfisdungs according to en Guarcbaiides can be explained by the fact that the.
