Abstract
The disclosed invention is directed toward an improved airspring bumper (20) and an airspring (10) comprising the improved bumper (20). The bumper (20) is defined by a dual reinforcing structure comprising concentric sets of ribs (50, 58) for absorbing and distributing loads generated from contact between the bumper (20) and an opposing retainer (16). The bumper (20) is secured to one of the airspring retainers (18) by a compression fit between the retainer (18) and the bumper (20) or by a central barbed post (36).
