  • Method of dyeing a webbing of a seat belt device
    Patent number: 5385584
    Abstract: A method of dyeing a webbing of a seat belt device having a step of padding a dye to a raw material for a webbing and a subsequent step of introducing the webbing into a hot blow furnace and color developing, wherein a webbing in a moistened state by padding of the dye is introduced into a hot blow furnace and drying and color development are conducted in the hot blow furnace.

  • Inflatable seatbelt system
    Patent number: 5385367
    Abstract: An inflatable seatbelt system designed so that the thickness of the webbing, when maintained in a strap-like configuration, is minimized, and it is possible to eliminate the webbing folding process and to reduce the amount of base fabric used and yet possible to reliably inflate the webbing when an emergency situation occurs. A shoulder belt (2) is formed from a tubular webbing (17), a tube (16) inserted in the webbing (17), and a cover (15) covering the webbing (17). The tube (16) is made of an elastic material which can be formed relatively thin and which has heat resistance and relatively high strength, e.g., urethane rubber or silicone rubber. The cover (15) is made of a resin material, e.g., polyester. The webbing (17) is made of a knitted fabric formed into a tubular configuration by weft knitting. By the use of the knitted fabric, the webbing (17) is stretchable to a large extent in the lateral direction but does not practically stretch in the longitudinal direction.

  • Inflatable seatbelt system
    Patent number: 5354096
    Abstract: An inflatable seatbelt system having a webbing (11) formed in the shape of a bag from a woven fabric. The warp of the webbing (11) is disposed in the longitudinal direction of the seatbelt, and the weft is disposed in the lateral direction of the seatbelt. The weft is formed of spandex threads made of a material having a relatively low modulus of elasticity and stretchable in a rubber-like manner, e.g., urethane. The weft (15) on the reverse side of a portion of the webbing (11) corresponding to the boundary between a shoulder belt (2) and a lap belt (3) is cut over a predetermined area. A gas outlet portion (5e) of a tongue (5) is inserted into the shoulder belt (2) from an opening 11(c) formed by widening the cut area of the weft (15).
