Abstract

A new and improved air bag inflator module adapted for quick action, snap-on, permanent mounting on a steering wheel requires the use of no tools to install. The module is pre-positioned in front of the steering wheel and is thrust into place until locked. The inflator module includes a base facing and movable in one direction directly toward the steering wheel with a plurality of quick action, snap-on type fasteners carried thereby. Each fastener has a first portion extended into an opening in the steering wheel as the inflator module is pushed into place with a unidirectional thrust and a second portion for supporting the first portion projecting outwardly thereof. A snap-action, annular compressible and expandable holding skirt is provided on the first portion of each fastener for lockingly engaging a surface on the steering wheel when expanded after the first portion of the fastener is fully inserted through an aligned opening in the steering wheel. The holding skirt is initially compressed while passing through an opening and after passage automatically springs back and expands to engage a surface on the steering wheel for permanently retaining the fastener in interconnecting relation therebetween. First and second portions of each fastener are releasable from one another using an ordinary hand tool such as a screw driver for permitting the inflator module to be bodily removed from the steering wheel after installation. The hand tool may also be used for reassembling the first and second portions of each fastener so that the inflator module may be remounted on the steering wheel.
