ANTI-RATTLE AND RETENTION STRUCTURE FOR A FLANGELESS INFLATOR OF AN AIRBAG RESTRAINT ASSEMBLY

摘要

RATTLE AND RETENTION STRUCTURE FOR A FLANGELESS INFLATOR OF AN AIRBAG RESTRAINT ASSEMBLY An inflator, which is shorter than a reaction can of an airbag restraint assembly and which has a flangeless base at one end thereof, is mounted in the reaction can. The mounting structure for the flangeless inflator has a generally circular open cylindrical shape, with its sidewall terminated at a first end in a mounting flange and terminating on the other end thereof in a resilient arm flared radially outward at the end thereof. Preferably, intermediate the mounting flange and the resilient arm is a radially-inwardly-extending integral circumferential rib or discrete dimples. The mounting flange of the mounting structure is located in an opening in an end wall of the reaction can, with the resilient arm frictionally engaging and holding the flangeless base of the inflator in the reaction can while the intermediate rib or discrete dimples prevent any significant rearward axial movement of the inflator in the reaction can thereby providing essentially rattle- and squeak-free retention of the flangeless based inflator in the reaction can in an appropriately positioned and centered manner.
