Abstract
Igniters for use in airbag inflators are disclosed. The igniters are fabricated of consumable materials which produce essentially no solid by-products. The igniters, or parts thereof, can be formed by molding or extrusion processes. The invention also provides a consumable auto-ignition cap as part of one of the embodiments of the igniter assembly.
Claims35
An igniter for use in a vehicle airbag assembly comprising an igniter material which is maintained in its intended functional shape by a solid body of a consumable material which is essentially consumed to a non-solid phase upon ignition of the igniter material.
An igniter assembly for an automotive airbag comprising an igniter shell which encompasses igniter material, wherein said shell is made of a solid material which is consumed producing essentially no solid by-products during ignition of the igniter.
In a gas generator for inflating automotive airbags which includes an igniter material in an igniter tube, a gas generating composition surrounding said tube, and means to initiate ignition of said igniter material, the improvement which comprises providing said igniter tube from an organic composition which is consumable producing essentially no solid by-products during said ignition.
An igniter assembly for a vehicle airbag restraint system comprising:
- (a) a shell of a solid material,
- (b) an igniter material effectively shaped by said shell, and
- (c) a cap sealing one end of the shell, said cap being fabricated from a material which has an auto-ignition temperature between 300.degree. and 450.degree. F.
