Abstract
The invention provides an initiator assembly that can be easily manufactured without increasing cost, and can be easily and securely connected to a connector when it is used. The initiator assembly includes a priming for being used in a motor vehicle, an initiator used for igniting the priming and having at least one conductive pin and a metal collar for fixing the initiator assembly on an inflator that are integrally formed by an insulating material injection-molded therebetween. The insulating material is a resin made of a plastic material that surrounds a metal eyelet of the initiator.
Claims16
An initiator assembly including a priming for being used in an air bag inflator, comprising:
- an initiator used for igniting the priming and having at least one conductive pin;
- a metal collar for fixing the initiator assembly on the air bag inflator, said metal collar and said initiator being integrally formed by an insulating material injection-molded therebetween, said metal collar including a circumferential wall portion extending in an axial direction thereof and the insulating material including a projection formed on an outer peripheral surface thereof such that an outer end of the projection is projected from a surface defined by an outer surface of the circumferential wall portion, wherein
- the outer peripheral surface of the insulating material and the outer surface of the circumferential wall portion are exposed in juxtaposed relation to each other and have substantially the same diameter, and wherein
- the insulating material is a resin made of a plastic material that surrounds a metal eyelet of the initiator.
An initiator assembly including a priming for being used in an air bag inflator, comprising:
- an initiator for igniting the priming and having at least one conductive pin;
- a metal collar for fixing the initiator assembly on the air bag inflator, said metal collar and said initiator being integrally formed by an insulating material injection-molded therebetween, said metal collar including a circumferential wall portion extending in an axial direction thereof and the insulating material including a projection formed on an outer peripheral surface thereof such that an outer end of the projection is projected from a surface defined by the outer surface of the circumferential wall portion, wherein
- the outer peripheral surface of the insulating material and the outer surface of the circumferential wall portion are exposed in juxtaposed relation to each other and have substantially the same diameter, and wherein
- the projection increases a friction between an inner tube of the air bag inflator and the initiator assembly when the initiator assembly is provided within the tube.
An initiator assembly including a priming for being used in an air bag inflator, comprising:
- an initiator for igniting the priming and having at least one conductive pin;
- a metal collar for holding the initiator assembly with respect to the air bag inflator, said metal collar and said initiator being integrally formed by an insulating material injection-molded therebetween, said metal collar including a circumferential wall portion extending in an axial direction thereof and the insulating material including a projection formed on an outer peripheral surface thereof such that an outer end of the projection is projected from a surface defined by the outer surface of the circumferential wall portion, wherein
- the outer peripheral surface of the insulating material and the outer surface of the circumferential wall portion are exposed in juxtaposed relation to each other and have substantially the same diameter, and wherein
- the metal collar includes a cavity in a rear half portion thereof, that is not covered with the insulating material and an inner peripheral surface of the cavity is exposed.
