Abstract
An initiator assembly for placement in an associated opening in an initiator-containing device includes an initiator device having at least one igniter element and an elastomeric overmoulding. The initiator device includes at least one of a thermoplastic initiator base and a thermoplastic adapter integrally joined to a base of the initiator-containing device. The elastomeric overmoulding is integral with at least one structural component such as the initiator base, the adapter and the base of the initiator-containing device. The elastomeric overmoulding serves to sealingly mate the initiator assembly in an initiator-accepting opening in the initiator-containing device. Also provided are corresponding methods of making an initiator assembly.
Claims20
An initiator assembly for an initiator-containing device, the initiator assembly comprising:
- an initiator device including at least one igniter element, the initiator device having at least one element selected from the group consisting of a thermoplastic initiator base and a thermoplastic adapter integrally joined to a base of the initiator-containing device and
- an elastomeric overmoulding to sealingly mate the initiator assembly in an initiator-accepting opening directly to a gas storage or generation chamber in the initiator-containing device, the elastomeric overmoulding integral with at least one structural component selected from a group consisting of said thermoplastic initiator base, said thermoplastic adapter and said base of the initiator-containing device, the elastomeric overmoulding at least in part disposed on an outer surface of the selected structural component.
In an initiator assembly for placement in an initiator-containing automotive safety restraint inflator device, the initiator assembly including at least one igniter element and a structural element having an outer surface, the improvement comprising:
- an integral elastomeric overmoulding disposed on at least a portion of the outer surface of the structural element to form a seal to sealingly mate the initiator assembly in an initiator-accepting opening directly to a gas storage or generation chamber in the inflator device.
A method of making an initiator assembly, the method comprising:
- molding an elastomeric seal about at least a portion of an outer surface of an initiator assembly structural element, the elastomeric seal to sealingly mate the initiator assembly in an initiator accepting opening directly to a gas storage or generation chamber in an initiator containing device.
