Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
163 words
A shock absorber fastening at a vehicle bumper comprising a cylindrical shock absorber housing; an impact plate externally fixed to an end of said shock absorber housing, said impact plate having a diameter substantially larger than the diameter of said cylindrical housing; a metal cap member detachably secured to a vehicle bumper, said metal cap member having an aperture through which said end of said shock absorber housing extends; and an elastic shock absorbing bearing material contained in said metal cap member for embedding said end of said shock absorber housing and said impact plate within said metal cap member such that said end of said shock absorber housing and said impact plate are both elastically supported by said elastic shock absorbing bearing material, wherein said elastic shock absorbing bearing material is configured to bear against the bumper at a portion apart from said shock absorber housing to absorb direct impacts on said bumper and to transmit said impacts to said impact plate.
