Abstract
Abstract A one piece laminated air bag has an inner layer of sheet material, a middle layer of load carrying fibers and an outer layer of sheet material. The load carrying fibers are laid in a pre-specified pattern such that a majority of loads in the air bag are carried by the fibers. The method of manufacturing the air bag includes an inflatable mold which is inflated to the required configuration, covered with the various layers and deflated after the laminating of sheets to form the one piece laminated air bag.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
131 words
A three dimensional air bag comprising: a first layer of material; and a plurality of discrete load carrying fibers disposed on said first layer of material in a pre-specified configuration, said pre-specified configuration corresponding with a pattern defining high and low stress areas of said first layer of material when said air bag is deployed such that a higher concentration of said discrete load carrying fibers are present in said high stress areas of said first layer of material for reinforcing said high stress areas of said first layer of material and more discrete fibers being present in said high stress areas of said first layer of material and more discrete fibers being present in said high stress areas than in said low stress areas of said first layer of material.
Claim 2
Dependent Claim
131 words
A three dimensional air bag comprising: a first layer of material; and a plurality of discrete load carrying fibers disposed on said first layer of material in a pre-specified configuration, said pre-specified configuration corresponding with a pattern defining high and low stress areas of said first layer of material when said air bag is deployed such that a higher concentration of said discrete load carrying fibers are present in said high stress areas of said first layer of material for reinforcing said high stress areas of said first layer of material and more discrete fibers being present in said high stress areas of said first layer of material and more discrete fibers being present in said high stress areas than in said low stress areas of said first layer of material.
