1. An initiator assembly for use in a vehicle, comprising:
- an initiator including at least one conductive pin having a length; and
a collar assembly joined to said initiator and including;
an injection-molded insulating material surrounding at least portions of said initiator, said insulating material extending in a direction of said length of said at least one conductive pin and defining a mating interface that contains at least portions of said at least one conductive pin; and
an insert member joined by injection molding to said insulating material and including a body member and a shoulder integral therewith, said body member having an interior section with an inward length extending inwardly within said insulating material and said shoulder having an outward length extending outwardly from said insulating material;
wherein said outward length of said shoulder is less than twice said inward length of said interior section.

Abstract
An initiator assembly for use with an inflator in a vehicle is provided. The initiator assembly includes an integral, one-piece insert member that is injection molded with insulating material to an initiator. The insert member suitably engages an initiator adapter for properly holding the initiator assembly in place relative to the inflator housing both before and after the initiator assembly is ignited. The insert member can include a number of different embodiments, each of which is characterized by the relatively short length of the shoulder that engages the initiator adapter.

4. An initiator assembly for use in a vehicle, comprising:
-
an initiator including an initiator charge and at least one conductive pin having a length used in igniting said initiator charge; and a collar assembly joined to said initiator and including; an injection-molded insulating material surrounding at least portions of said initiator, said insulating material extending in a direction of said length of said at least one conductive pin and defining a mating interface including a cavity containing at least first portions of said at least one conductive pin; and a non-planar insert member with a height extending in a direction of said length of said at least one conductive pin, said insert member having inner portions, including at least first inner portions being located within said insulating material and being surrounded by said insulating material and said insert member having outer portions being located outwardly of said insulating material wherein, when a device is to be activated using said initiator charge, at least some of said outer portions contact and support the device. - View Dependent Claims (5, 6, 7, 8, 9)
