Abstract
Abstract A vehicle bumper system and apparatus is disclosed herein having a plate mountable on the chassis of a vehicle which supports an inflatable member carried by a holder. The holder is resiliently supported on the plate by means of a pair of mountings taking the form of a hydraulic shock absorber and a leaf spring arrangement. The inflatable member is reinforced by layers of fibers as well as reinforcing rods that are critically located so as to form mounting lobes detachably connected to the opposing edges of an elongated slot formed in the holder.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
163 words
A bumper system and apparatus therefor to be carried on a chassis of a vehicle, the combination comprising: an impact receiving member; articulated resilient means mounting said impact receiving member to said chassis; said articulated resilient means providing both hydraulic and spring shock absorption and said impact receiving member provides pneumatic shock absorption; said impact receiving member is an elongated inflatable member and said resilient means includes a pair of leaf spring assemblies; said impact receiving member further includes a pair of piston and cylinder assemblages separated by said leaf spring assemblies; a holder releasably carrying said inflatable member and said articulated resilient means pivotally interconnecting said holder to said vehicle chassis; and said inflatable member includes a carcass having a pair of grooves provided on opposite sides thereof adjacent an elongated bead and said holder includes a slot for slidably receiving said inflatable member whereby opposing edges of said holder defining said slot slidably engage with said grooves and said bead respectively.
Claim 2
Dependent Claim
