Airbag inflator with snap-on mounting attachment
First Claim
1. A snap-on mounting attachment for securing an airbag inflator module having a base plate to a support provided on a steering wheel of a motor vehicle, the snap-on mounting attachment comprising:
- A) a fastener stud with at least one yieldable, outwardly-biased holding barb, the fastener stud secured to and extending from one of the airbag inflator module base plate and the vehicle support; and
B) a snap receptor mounted on the other of the airbag inflator base plate and vehicle support, the snap receptor having a limited range of lateral and vertical movement providing a floating encapturement for the snap receptor with respect to the other of the airbag inflator and vehicle support, the snap receptor comprising a ring embedded in a shell, the ring surrounding and at least partially defining a stud receiving opening extending therethrough for accommodating the fastener stud and the ring further defining a lip for engaging the at least one vieldable holding barb, the floating encapturement permitting a limited range of movement of the snap receptor for alignment of the snap receptor with the fastener stud and for accommodating tolerances in the airbag inflator module, steering wheel, and snap-on mounting attachment,whereby insertion of the fastener stud into the snap receptor opening engages the holding barb with the snap receptor to secure the airbag inflator module to the vehicle support.

Abstract
A snap-on mounting attachment is provided for securing an airbag inflator module having a base plate to the steering wheel of a motor vehicle. The mounting attachment includes two fastener studs extending rearwardly from the base plate, each fastener stud having a yieldable holding barb. Two capture brackets are mounted to the spokes of the steering wheel, and each capture bracket holds a snap receptor in floating encapturement therein, i.e., with a limited range of lateral and vertical movement. The snap receptors each have a metal ring embedded in a polymer shell and define a stud receiving opening therethrough with the metal ring defining a lip engaged by the holding barb of the fastener stud. Bias stops between the base plate and the steering wheel take up slack in the mounting attachment and eliminate rattles, and the polymer shell of the snap receptors also minimizes rattles. The steering wheel and airbag inflator module have complementary covers, and the floating encapturement permits alignment of the covers.

16. A snap-on mounting attachment for securing an airbag inflator module having a base plate to a support provided on a motor vehicle, the snap-on mounting attachment comprising:
-
A) two fastener studs secured at spaced apart locations on and extending from a base plate of an airbag inflator module, each fastener stud having at least one yieldable holding barb extending outwardly therefrom; B) two capture brackets respectively mounted to a support on a motor vehicle; C) two snap receptors, each comprising a metal ring embedded in a polymer shell and defining a stud receiving opening therethrough including a lip for engaging the at least one holding barb of one fastener stud, the snap receptors respectively mounted in the two capture brackets and spaced-apart for receiving the two spaced-apart fastener studs, each snap receptor having a limited range of lateral and vertical movement providing a floating encapturement for the snap receptor with respect to the support on the motor vehicle; and D) at least two resilient bias stops mounted on one of the airbag inflator module and vehicle support and engaged therebetween for biasing the snap-on mounting attachment into rattle free condition. - View Dependent Claims (17)

18. A driver'"'"'s side passenger restraint system comprising:
-
A) a steering wheel having a rim, hub, and connecting spokes, and also having a cover extending over the rim and a portion of the spokes extending inwardly from the rim; B) two capture brackets mounted at spaced apart locations on the spokes of the steering wheel; C) two snap-in receptors, each snap-in receptor having a metal ring embedded in a polymer shell and defining a stud receiving opening including a lip defined by the metal ring, each snap-in receptor respectively held in a corresponding capture bracket having a limited range of both lateral and vertical movement providing a floating encapturement for the snap-in receptor with respect to the capture bracket, the capture brackets exposing the stud receiving openings in the snap-in receptors in the range of movement afforded by the floating encapturement; D) an airbag inflator module including a base plate, inflator, airbag and cover, the cover shaped complementary to the cover of the steering wheel; and E) two fastening studs extending from spaced-apart locations on the base plate of the airbag inflator module, each fastener stud including at least one yieldable holding barb for engaging the lip of a corresponding snap-in receptor and the fastener studs being spaced on the module base plate for insertion through the snap-in receptors to mount the airbag inflator module to the steering wheel with the airbag inflator module cover and steering wheel cover in their complementary positions.
