Abstract
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).
Claims19
A seat belt (10) for a motor vehicle, comprising a webbing (12) that includes two webbing layers (28, 30), which define a webbing interior, and a heating layer (26) substantially in the webbing interior, the heating layer (26) including an electric heating element (24) having an end penetrating one of the webbing layers (28, 30) from an interior surface of the penetrated webbing layer (28, 30) to an exterior surface of the penetrated webbing layer (28, 30), the penetrating end of the electric heating element (24) being connected to the exterior surface of the penetrated webbing layer (28, 30).
A seat belt (10) for a motor vehicle, comprising a webbing (12) that includes two webbing layers (28, 30), which define a webbing interior, and a heating layer (26) substantially in the webbing interior, each webbing layer (28, 30) including yarns (32) of webbing material, the heating layer (26) including first yarns of an electric heating material (34) and second yarns (42) of webbing material, the first yarns of electric heating material (34) being configured to provide thermal heat when supplied with current, portions of the second yarns (42) of the heating layer (26) being connected to the yarns (32) of each webbing layer (28, 30).
A seat belt (10) for a motor vehicle, comprising:
- a first webbing layer (28) including first and second yarns of webbing material;
- a second webbing layer (30) including first and second yarns of webbing material, the first yarns of the second webbing layer (30) being connected to the second yarns of the first webbing layer (28) at the first webbing layer (28), the first yarns of the first webbing layer (28) being connected to the second yarns of the second webbing layer (30) at the second webbing layer (30);
- and
- a heating layer (26) interposed between the first and second webbing layers (28, 30), the heating layer (26) including conductive fibers (34) configured to provide thermal heat when supplied with current, the first yarns of each of the first and second webbing layers (28, 30) extending through the heating layer (26) between the conductive fibers (34) of the heating layer (26) to the other of the first and second webbing layers (28, 30).
