Disclosed is a high strength polyester fiber for a seat belt, and in particular, a polyester fiber for a seat belt, which has intrinsic viscosity of 0.8 to 1.5 dl/g, tensile strength of 8.8 g/d or more, and total fineness of 400 to 1800 denier. A method of preparing the fiber is disclosed. The polyester fiber includes filaments having high strength, low modulus, and high elongation to significantly lower shrinkage, while securing excellent mechanical properties, it is possible to manufacture a seat belt having excellent impact absorption and significantly improved abrasion resistance and heat resistant strength retention, even with a woven density of 260 yarns/inch or less.

The invention provides a seat belt (10) for a motor vehicle comprising a webbing (12) that includes a tubular portion (22) in which at least one electric heating element (24) is accommodated. The invention further provides a method for manufacturing such seat belt (10).

The invention provides a seat belt (10) for a motor vehicle comprising a webbing (12) that includes at least one chamber (24) in which at least one electric, especially band-shaped, heating element (26) is accommodated. The invention further provides a method for manufacturing such seat belt (10).

The invention describes a seat belt (10) for a motor vehicle comprising a webbing (12) that includes plural layers (26, 28, 30) at least one layer (26) of which comprises an electric heating element (26). The invention further describes a method for manufacturing such seat belt (10).

The webbing construction absorbs stress and pressures on the edge of the webbing. The webbing locks into various hardware or an adjustment bar along the length of the webbing, such as every 1/32″ for slippage control of the webbing. The webbing of the present invention reduces the memory of folds made over a long period of time with a long shelf life. The webbing construction of the present invention can be used in a wide array of applications, such as for clothing belts, seat belt webbing, watch bands, backpacks, straps and the like. As a result, the webbing of the present invention addresses the shortcomings of the prior art to provide a superior webbing construction.

A seat-belt heating assembly and a seat are provided. The seat-belt heating assembly includes a safety belt body and a safety-belt heating mechanism connected to the safety belt body. The seat includes a safety belt body, a seat body, a heating component, and a control component. The heating component includes a heating mechanism provided in the safety belt body. In the use state, the heating mechanism has one end terminating in the safety belt body at the front end of the fixing member, and the other end terminating in the safety belt body at the front end of the retractor. The control component includes an ECU heating controller, a safety-belt heating switch, and an insertion detection unit configured to detect whether the latch is inserted into the buckle. Each of the safety-belt heating switch, the insertion detection unit, and the heating mechanism is connected to the ECU heating controller.

A safety belt webbing for a vehicle includes a woven fabric from mutually intersecting warp and weft threads. The woven fabric is at least partially configured in the weave repeat with at least 6, preferably at least 8 ends. The weave repeat per warp thread includes at least four, preferably six, intersection points with the weft threads. The intersection points are weave points resulting between the warp and the weft threads when the warp thread within the weave repeat alternates from a warp elevation to a warp depression, or vice versa. Within the weave repeat the largest warp float per warp thread is across two weft threads, and the maximum warp depression is below two weft threads. Within the weave repeat, per warp thread there is at least one warp elevation additionally to the warp float across a weft thread, and at least one warp depression below a weft thread.

An occupant restraint belt webbing forms an occupant restraint belt to restrain a vehicle occupant, and includes a plurality of warp yarns and a plurality of weft yarns. The plurality of warp yarns and the plurality of weft yarns are woven so as to extend orthogonally to each other. The warp yarns include an infrared light absorption yarn, and a thickness of the infrared light absorption yarn differs from a thickness of each yarn of the plurality of wrap yarns other than the infrared light absorption yarn.

An occupant restraint belt webbing forms a long occupant restraint belt to restrain a vehicle occupant, and includes a plurality of warp yarns and a plurality of weft yarns. The plurality of warp yarns and the plurality of weft yarns are woven so as to extend orthogonally to each other. The warp yarns or the weft yarns include an infrared light absorption yarn.
