INFLATOR DEVICE WITH INTEGRAL CLAMP STOP
First Claim
Patent Images
1. A vehicular safety restraint inflator device, the inflator device comprising:
- a tubular housing to provide inflation gas to inflate an associated inflatable restraint device; and
a toroidal clamp stop positioned on the tubular housing to provide a hard stop for an inflator attachment clamp to secure the inflator device within an airbag module;
wherein a reactive material is contained within the tubular housing and reaction of the reactive material within the tubular housing generates an increase in pressure within the tubular housing, the inflator device additionally comprising;
an overwrap about at least a portion of the tubular housing to form an inflator assembly that withstands the pressure generated within the tubular housing upon reaction of the reactive material, the overwrap comprising a composite of fibers and a resin matrix system andwherein the toroidal clamp stop comprises a toroidal-shaped element disposed on the tubular housing with the composite overwrap disposed thereover.

Abstract
A vehicular safety restraint inflator device, the inflator device includes a tubular housing to provide inflation gas to inflate an associated inflatable restraint device and a toroidal clamp stop positioned on the tubular inflator housing. The clamp stop serves to provide a hard stop for an inflator attachment clamp to secure the inflator device within an airbag module and thus to minimize or avoid undesired lateral movement of the inflator device within a module assembly.
