Abstract
Abstract An energy absorbing assembly for rendering a vehicle more safe by absorbing and distributing energy upon impact of the vehicle bumper with a foreign object. The energy absorbing bumper assembly comprises an energy absorbing means which will absorb energy when the assembly is impacted at a first angle and which moves so as to not absorb energy when struck at a second angle different from the first angle, thus allowing the impact energy to be absorbed elsewhere on the bumper assembly.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
153 words
An energy absorbing bumper assembly comprising: bumper means for receiving an impact and including an elongated shell member and an elongated support member; energy absorbing means between said shell member and said support member; said energy absorbing means including a block of energy absorbing material between said shell member and said support member, said support member having a first surface thereon and said block having a coacting second surface immediately adjacent thereto, said first and second surfaces being disposed generally at an acute angle relative to the direction of elongation of said members, said second surface being forced against said first surface when said shell member receives an impact generally perpendicular to said surfaces to maximize the energy absorption by said block, said second surface being movable relative to said first surface in response to an impact which is other than perpendicular to said surfaces to reduce the energy absorbed by said block.
Claim 2
Dependent Claim
153 words
An energy absorbing bumper assembly comprising: bumper means for receiving an impact and including an elongated shell member and an elongated support member; energy absorbing means between said shell member and said support member; said energy absorbing means including a block of energy absorbing material between said shell member and said support member, said support member having a first surface thereon and said block having a coacting second surface immediately adjacent thereto, said first and second surfaces being disposed generally at an acute angle relative to the direction of elongation of said members, said second surface being forced against said first surface when said shell member receives an impact generally perpendicular to said surfaces to maximize the energy absorption by said block, said second surface being movable relative to said first surface in response to an impact which is other than perpendicular to said surfaces to reduce the energy absorbed by said block.
Claim 3
Dependent Claim
53 words
An assembly as set forth in claim 1, wherein said shell member includes a frontal surface and a rearwardly extending surface disposed about a corner from said frontal surface, said block being disposed at said corner, said second surface being movable relative to said first surface when said frontal surface is impacted frontally.
Claim 4
Dependent Claim
26 words
An assembly as set forth in claim 2, wherein said energy absorption means includes a surface disposed at an acute angle relative to said frontal surface.
Claim 5
Dependent Claim
24 words
An assembly as set forth in claim 3, wherein said bumper means includes a shell member having an upper portion and a lower portion.
Claim 6
Dependent Claim
21 words
An assembly as set forth in claim 4, wherein said surface is on said shell member in said upper portion thereof.
Claim 7
Dependent Claim
27 words
An assembly as set forth in claim 5, including additional energy absorbing means for absorbing energy when said bumper means is impacted on the frontal surface thereof.
Claim 8
Dependent Claim
24 words
An assembly as set forth in claim 6, wherein said additional energy absorbing means are disposed in said lower portion of said shell section.
Claim 9
Dependent Claim
16 words
An assembly as set forth in claim 7, wherein said shell section comprises foamed plastic material.
Claim 10
Dependent Claim
17 words
An assembly as set forth in claim 8, wherein said foamed plastic mateRial is microcellular polyurethane foam.
