Abstract
Abstract A vehicle bumper mounting construction formed of a generally elongated box-like housing member enclosing a portion of an elongated beam member generally H-shaped in cross section, one or more pairs of rubber pads having parallel surfaces are bonded, one surface to the web of the H-beam member and the other surface to the inside surface of the side walls of the housing. The housing member is provided with means for mounting the assembly to the frame of an automobile and the H-beam is provided with a mounting flange for attaching an automobile bumper to the assembly. Impact energy applied to the bumper is absorbed by the construction by deflection of the H-beam placing shear stress on the pairs of rubber pads.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
159 words
Vehicle energy absorbing bumper mount construction including an elongated housing having top and bottom walls and opposite side walls and open at each end, an elongated beam of generally H-shaped cross section, located within the housing and having a web portion spaced between the opposite side walls and top and bottom flanges spaced closely adjacent to the housing top and bottom walls respectively, a portion of the beam extending from the interior a distance beyond one open end of the housing, the other end of the beam being located adjacent to the other open end of the housing; energy absorbing elastic members bonded to opposite surfaces of the web and to the inside surfaces of the housing side walls, the elastic members mounting the beam within the housing, means for attaching the housing to the frame of a vehicle and means for attaching a vehicle bumper to the end of the beam extending beyond the interior of the housing.
Claim 2
Dependent Claim
159 words
Vehicle energy absorbing bumper mount construction including an elongated housing having top and bottom walls and opposite side walls and open at each end, an elongated beam of generally H-shaped cross section, located within the housing and having a web portion spaced between the opposite side walls and top and bottom flanges spaced closely adjacent to the housing top and bottom walls respectively, a portion of the beam extending from the interior a distance beyond one open end of the housing, the other end of the beam being located adjacent to the other open end of the housing; energy absorbing elastic members bonded to opposite surfaces of the web and to the inside surfaces of the housing side walls, the elastic members mounting the beam within the housing, means for attaching the housing to the frame of a vehicle and means for attaching a vehicle bumper to the end of the beam extending beyond the interior of the housing.
Claim 3
Dependent Claim
48 words
Energy absorbing bumper mount construction as defined in claim 1 in which the energy absorbing members are rubber pads having two opposite surfaces, one of said surfaces bonded to a web surface and the opposite surface bonded to one of the inside surfaces of the housing side wall.
Claim 4
Dependent Claim
32 words

Claim 5
Dependent Claim
51 words
Energy absorbing bumper mount construction as defined in claim 1 in which said housing and said beam are formed of metal and in which rubber sheets are bonded to the top and bottom flanges of the beam in a position interposed between respectively the top and bottom walls of the housing.
Claim 6
Dependent Claim
33 words
Energy absorbing bumper mount construction as defined in claim 1 in which said energy absorbing members are first vulcanized bonded to the web of the beam, and then post-bonded to the housing surfaces.
Claim 7
Dependent Claim
30 words
Energy absorbing bumper mount construction as defined in claim 1 in which longitudinal movement of the beam within the housing will induce shear stress in the energy absorbing elastic members.
Claim 8
Dependent Claim
41 words

Claim 10
Dependent Claim
32 words
Energy absorbing bumper mount construction as defined in claim 8 in which longitudinal deflection of the beam in one direction will both induce shear stress in and compress said energy absorbing member.
Claim 11
Dependent Claim
160 words
Vehicle energy absorbing bumper mount construction including an elongated housing having top and bottom walls and opposite side walls, and open at each end, an elongated beam of generally H-shape cross section located within the housing and having a web portion spaced between the top and bottom housing walls, and flanges spaced closely adjacent to the opposite housing side walls, a portion of the beam extending from the interior a distance beyond one open end of the housing, the other end of the beam being located adjacent to the other open end of the housing, energy absorbing elastic members bonded to opposite surfaces of the web and to the inside surfaces of the top and bottom walls of the housing, the elastic members mounting the beam within the housing, means for attaching the housing to the frame of a vehicle, and means for attaching a vehicle bumper to the end of the beam extending beyond the interior of the housing.
Claim 12
Dependent Claim
160 words
Vehicle energy absorbing bumper mount construction including an elongated housing having top and bottom walls and opposite side walls, and open at each end, an elongated beam of generally H-shape cross section located within the housing and having a web portion spaced between the top and bottom housing walls, and flanges spaced closely adjacent to the opposite housing side walls, a portion of the beam extending from the interior a distance beyond one open end of the housing, the other end of the beam being located adjacent to the other open end of the housing, energy absorbing elastic members bonded to opposite surfaces of the web and to the inside surfaces of the top and bottom walls of the housing, the elastic members mounting the beam within the housing, means for attaching the housing to the frame of a vehicle, and means for attaching a vehicle bumper to the end of the beam extending beyond the interior of the housing.
Claim 13
Dependent Claim
