The invention is directed to coating a plurality of polyurethane films onto a stretchable knit fabric substrate and heat sealing such substrates together to yield an air curtain or air bag having improved air-holding properties.

Substrate with stretch and heat sealing properties to make a multidirectional restraint module design

The invention is directed to applying a plurality of polyurethane coating layers to a knit, woven or non-woven fabric substrate, following by sealing of two of such coated substrates together by radio frequency sealing, hot air sealing, or ultrasonic sealing to form an improved air-holding restraint system, such as an air curtain or air bag with superior air-holding characteristics.

Polyurethane coated fabrics for use in air-holding vehicle restraint systems

The invention is directed to coating a knit, woven, or non-woven textile substrate with adhesive polyurethane layer and then with an elastomeric polysiloxane layer and to then form an air curtain or air bag therefrom with superior air-holding and superior heat resistance.

Polysiloxane coated fabrics for use in air-holding vehicle restraint systems

The invention is directed to multi-layered textile fabrics having a plurality of polymeric coating layers of polyurethane and/or polysiloxane coated thereon. The coating layers are applied to such multi-layered woven textile fabric substrates having preconfigured air-holding cavities therein to form an improved air-holding vehicle restraint system, such as an air bag or side air curtain with superior air-holding characteristics. In certain instances, the multi-layered textile fabrics are coated on one side only, and in others they may be coated on both sides, i.e., opposed first and second surfaces. The layers of the multi-layered fabric can then be joined by means of heat sealing, RF welding or combinations thereof, for purposes of forming an air bag or side air curtain without the need for sewing or stitching. The coated fabrics facilitate manufacture of air bags, side curtains or the like with both reduced cutting and sealing steps than fabrics of the prior art.

Coated multi-layered woven textile fabrics for use in air-holding vehicle restraint system

A coated woven textile fabric is disclosed which is formed of synthetic yarns of more than one denier preferably synthetic filamentary yarns of differing deniers. A polymeric coating such as polyurethane is layered on at least one side thereof, but may also be provided on both sides. The combination of yarns of different deniers provides a superior adhesion surface for the polymeric coating. The yarns and the polymeric coating are preselected respectively in deniers and thickness so as to render the fabric substantially impermeable to fluid under pressure, while maintaining superb packageability and antiblocking properties for use in vehicle occupant restraint systems. A flexible lightweight air bag for receiving and containing fluid under pressure for use in a vehicle air restraint system is also disclosed, incorporating the woven textile fabric of the invention.

Coated multi-denier mixed fabrics for use in inflatable vehicle restraint systems

Polysiloxane coated fabrics for use in air bags

The present invention relates to a sound attenuation composite and a method for making the composite. The sound attenuation composite includes a barrier layer and an open cell foam layer loaded with a sound blocking filler. In one embodiment, the foam layer is filled with a barium sulfate filler. In another embodiment, a solid polyvinyl chloride barrier layer is loaded with barium sulfate, wherein 60 parts of barium sulfate is present in each 100 parts of polyvinyl chloride.
