Embodiment Construction

[0013] The seat belt webbing can be subdivided into a central part A and an edge part B. In the central part A there are provided warp threads 1 which have a texture of 900 to 2100 decitex (dtex) and are designed as multifilaments comprising untwisted monofilaments or twisted up to each Monofilament with 150 twists in meter length. The warp thread 1 has the function of absorbing the tensile forces that occur in the event of an accident and is therefore particularly strong and therefore also relatively stiff. In the edge section B there are thinner warp threads 3 having a texture of 400 to 1100 dtex, which are also designed as multifilaments, comprising eg 28 filaments. The monofilaments are twisted together to form up to 150 times per meter of length.

[0014] Furthermore, there is provided a weft thread 2 which, when weaving the seat belt webbing, is shuttled by a weft needle from one side, through a shed formed by two layers of warp threads 1 and 3 which are angularly alig...

Abstract

The invention relates to a sideband of a seat belt. The sideband comprises a plurality of warps (1 and 3), a weft (2) and a lock clamp wire (5), wherein the weft operates from one edge of the sideband of the seat belt to the other edge, is periodically rotated in the reverse direction at an inversion point and is interweaved with the warps (1 and 3); the weft (2) is turned back at the inversion point in an edge part (B) to form a ring; and the lock clamp wire (5) penetrates through the ring of the weft (2) for feed motion. The sideband is characterized in that the lock clamp wire (5) is placed between the warps (1 and 3), and is covered by the weft (2) and / or the warps (1 and 3) towards the surface of the sideband of the seat belt.

Description

technical field [0001] The invention relates to a seat belt webbing comprising the features in the preamble of claim 1 or 6 and to a method of manufacturing said seat belt webbing. Background technique [0002] Seat belts are used, for example, in motor vehicles, aircraft, and other mobile devices to restrain occupants. To fulfill their function, seat belts need to exhibit a preset tensile strength. Furthermore, in order for the occupant to be hindered as little as possible by the seat belt and for the occupant's clothing not to be damaged, the seat belt should generally comprise surfaces and soft edges that exhibit as little friction as possible. [0003] The seat belt webbing comprises a plurality of warp threads running in a longitudinal direction, the warp threads being connected to each other by weft threads running transversely to the warp threads. During the weaving process, the weft thread is shot through the warp thread from one side of the belt webbing with a wef...
