Abstract
Abstract A shock absorbing vehicle bumper assembly, in which a bumper is supported by a plurality of shock absorbing units connected between the bumper and the frame of a vehicle, such as one of the automotive type. The shock absorbing units are so mounted as to provide a resilient resistance toward compression in response to an impact tending to move the bumper toward the vehicle frame, and the units being arranged so as to restore the bumper to its initial outer position spaced from the frame following a shock or impact. The units are also arranged to permit a lateral movement of a bumper relatively to the longitudinal axis of the vehicle in the event the impact occurs at one side of the central region of the bumper, in a manner such that the curved end of the bumper will not damage the vehicle body. The shock absorbing units will also have a cushioning effect and the ability to absorb at least a material portion of the energy provided by an impact.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
A shock absorbing assembly for attaching a channel shaped bumper to a vehicle in a manner leaving the entire outer face of the bumper free and clean from any visible connecting part, wherein the improvement comprises at least two substantially parallel shock absorbing units, first connecting means attaching one end of each unit to the vehicle in a manner permitting lateral Pivotal movement of the unit relatively to the vehicle, and second connecting means attaching the opposite end of each unit to the bumper inside the channel thereof, said second connecting means including an elongated plate member attached to the shock absorbing unit, an elongated mounting yoke member for attachment to the inside of the bumper and an elongated elastomer member mounted between said plate member and said mounting yoke member, said plate member, elastomer member and mounting yoke member being secured to each other and extending transversely to the axis of the shock absorbing unit.
Claim 2
Dependent Claim
156 words
A shock absorbing assembly for attaching a channel shaped bumper to a vehicle in a manner leaving the entire outer face of the bumper free and clean from any visible connecting part, wherein the improvement comprises at least two substantially parallel shock absorbing units, first connecting means attaching one end of each unit to the vehicle in a manner permitting lateral Pivotal movement of the unit relatively to the vehicle, and second connecting means attaching the opposite end of each unit to the bumper inside the channel thereof, said second connecting means including an elongated plate member attached to the shock absorbing unit, an elongated mounting yoke member for attachment to the inside of the bumper and an elongated elastomer member mounted between said plate member and said mounting yoke member, said plate member, elastomer member and mounting yoke member being secured to each other and extending transversely to the axis of the shock absorbing unit.
Claim 3
Dependent Claim
15 words
The shock absorbing assembly of claim 1, wherein the bumper is carried by said units.
Claim 4
Dependent Claim
67 words
The shock absorbing assembly of claim 1, wherein said first connecting means comprise a U-shaped bracket element with the arms thereof disposed one above the other, a lug element extending between said arms, and a pivot pin extending through said arms and said lug, one of said elements being secured to said vehicle and the other element to the adjacent end of the respective shock absorbing unit.
Claim 5
Dependent Claim
33 words
The shock absorbing assembly of claim 1, wherein said first connecting means comprise like studs extending from the vehicle and adjacent end of the respective unit, and an elastomeric element connecting said studs.
Claim 6
Dependent Claim
47 words
The shock absorbing assembly of claim 4, wherein each of said studs is provided with an enlarged head, and said elastomer is shaped to extend between the confronting faces of said heads and integrally over the circumference and inwardly over the opposite side of each said head.
Claim 7
Dependent Claim
30 words
The shock absorbing assembly of claim 5, including upper and lower guide plates adjacent said elastomer to limit the pivotal movement of the respective unit to substantially a horizontal plane.
Claim 8
Dependent Claim
31 words
The shock absorbing assembly of claim 1, wherein said shock absorbing units are conventional automotive telescopic shock absorbers including a cylinder with a piston therein and a piston rod protruding therefrom.
