The fabric structure of a belt intended for use as a vehicle safety belt is characterised by warp (1) and weft (3) threads, wherein the warp threads (1) extend in the lengthwise direction of the belt (2) and the weft threads (3) extend in the transverse direction thereto, wherein in the load-free state the warp threads (1) are looped around the weft threads (3) which extend in a straight line and wherein at least in a lengthwise section of the belt the weft threads (3) are formed in such a manner that they can extend in length in comparison to the warp threads (1). In this manner, the risk of injury to vehicle occupants during an accident, thus when a load is applied in the lengthwise direction of the belt, is reduced by virtue of the fact that the warp threads which are not able to extend in length relative to the weft threads starting from their shape looped around the weft threads (3) are aligned in a straight line in accordance with the applied load, so that a displacement force is exerted on the weft threads (3) and these are stretched to form a shape which is now looped around the warp threads (1), so that the warp threads are moved away from each other and the belt band width is increased.
