Problems solved by technology

[0003] However, the currently used widthwise dimensions of such a belt are not considered to be optimal, because in the event of an accident it could lead to locally excessive physical concentration according to the widthwise dimension according to the forces to be transmitted via the belt. load and the consequent risk of injury, which can be significant especially when the occupant is in an unfavorable body position

Embodiment Construction

[0016] according to figure 1 The tape fabric of FIG. 2 shows the weave pattern between warp threads 1 running in the longitudinal direction 2 of the tape and weft threads 3 running transversely to the warp threads 1 . It can be seen that the weft threads 3 are each present in a double arrangement 5 , whereas the warp threads 1 are always wound around two such successive arrangements 5 . It can also be seen that the successive warp threads 1 along the transverse direction 4 are each offset by one such arrangement along the longitudinal direction 2 .

[0017] Just to illustrate the fabric structure, figure 1 In particular, an arrangement of the warp threads 1 separated by a wide distance from one another is shown. while in figure 2 In the actual product shown, the warp threads 1 lie closely against one another, wherein the warp threads 1 lying sideways against one another form a unique surface structure due to the offset arrangement in the longitudinal direction 2 .

Abstract

The invention relates to a belt for use as a vehicle safety belt, characterized by warp (1) and weft threads (3), wherien the warp threads (1) extend in the longitudinal axis of the belt (2) and the weft threads (3) extend transverely thereto, wherein the warp threads (1) are wound about the weft threads in the unencumbered state, and wherein at least in a longitudinal segment of the belt the weft threads (3) are designed to be extendable in length relative to the warp threads (1). In this manner, in case of an accident, thus, under a load applied in the longitudinal axis of the belt, the risk of injury to vehicle occupants is reduced in that the warp threads that are not extendable in length relative to the weft threads are aligned in straight lines under the applied load, due to the wound shape thereof about the weft threads (3), so that a displacement force acts on the weft threads (3), and said weft threads are stretched to a shape wound about the warp thread (1), so that the warpthreads separate from one another and the belt width increases.

Description

technical field [0001] The invention relates to a belt according to the preamble of claim 1 . Background technique [0002] Seat belts for automobiles, usually connected to a seat belt tensioner controlled by the operating state of the car, have a width of typically 46mm to 48mm. In the event of an accident, they are intended to protect the occupants of the vehicle against uncontrolled centrifugal movements leading to a significant risk of injury without unduly restricting their freedom of movement under normal operating conditions. These safety belts have in fact proven particularly effective and have made a significant contribution to the reduction of serious accident injuries since their general introduction in road traffic. [0003] However, the currently used widthwise dimensions of such a belt are not considered to be optimal, because in the event of an accident it could lead to locally excessive physical concentration according to the widthwise dimension according to...
