ABSTRACT:
An impact absorbing bumper consisting of a housing and resilient impact receiving member having an inner portion slidably mounted in the housing and an outer portion extending through an opening in the housing and engaging an inner tube containing air under pressure positioned in the housing. Upon impact the inner portion acts as a piston against air under pressure in the inner tube to absorb most of the impact force, while the inherent resiliency of the impact receiving member absorbs part of the impact force as well as upon becoming distorted by the impact, increased resistence is offered at the opening to the sliding movement of the impact receiving member.
