Abstract
Abstract An impact-absorbing bumper comprised of a strip composed of a resilient material and a plurality of fasteners embedded at spaced intervals therealong which project outwardly of the rear mounting face of the strip. Each fastener is comprised of a plurality of outwardly projecting engaging legs which are biased in a mutually separating direction and into interlocking engagement with the edges of an aperture provided in a mounting plate on which the bumper strip is to be installed. The separating bias on the engaging legs of each fastener is primarily achieved by an integrally formed rearwardly projecing portion of the resilient material which extends between the inner surfaces of the engaging legs, thereby preventing inadvertent disengagement of the fasteners from the mounting plate as a result of shocks and vibrations.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
100 words
An impact-absorbing bumper assembly comprising a body section composed of a resilient material and defining an impact face and a mounting face, and at least one fastener embedded in said body and projecting outwardly of the mounting face thereof, each said fastener formed with a plurality of longitudinally extending deflectable engaging legs incorporating engaging means thereon adapted to engage the edges of an aperture of a mounting member on which said bumper assembly is to be mounted, and biasing means including a section of said body disposed between said engaging legs for biasing said legs in mutual divergent separating relationship.
Claim 2
Dependent Claim
100 words
An impact-absorbing bumper assembly comprising a body section composed of a resilient material and defining an impact face and a mounting face, and at least one fastener embedded in said body and projecting outwardly of the mounting face thereof, each said fastener formed with a plurality of longitudinally extending deflectable engaging legs incorporating engaging means thereon adapted to engage the edges of an aperture of a mounting member on which said bumper assembly is to be mounted, and biasing means including a section of said body disposed between said engaging legs for biasing said legs in mutual divergent separating relationship.
Claim 3
Dependent Claim
35 words
The bumper assembly as defined in claim 1, wherein said body is in the form of an elongated strip and a plurality of fasteners are embedded in longitudinally spaced intervals along said mounting face thereof.
Claim 4
Dependent Claim
34 words
The bumper assembly as defined in claim 1, wherein said section of said body member disposed between said engaging legs extends to a position substantially adjacent to the outer projecting ends of said legs.
Claim 5
Dependent Claim
28 words
The bumper assembly as defined in claim 1, wherein said fastener is of a generally U-shaped configuration with the bight section thereof embedded and interlocked in said body.
Claim 6
Dependent Claim
23 words
The bumper assembly as defined in claim 1, wherein said resilient material comprises a deformable elastomer and said fastener is composed of steel.
Claim 7
Dependent Claim
28 words
The bumper assembly as defined in claim 1, wherein each said fastener is comprised of a pair of said engaging legs which extend in spaced substantially parallel relationship.
Claim 8
Dependent Claim
54 words
The bumper assembly as defined in claim 1, wherein said engaging means comprises an engaging tang integrally formed with said engaging leg and projecting outwardly of the plane thereof, said tang having an engaging edge oriented towards said mounting face for engaging the rear face of a mounting member when in an installed position.
Claim 9
Dependent Claim
36 words
The bumper assembly as defined in claim 7, wherein the outer end portions of said engaging legs are formed with a converging taper to facilitate entry of the end of said fastener in a receiving aperture.
Claim 10
Dependent Claim
66 words
The bumper assembly as defined in claim 1, wherein each said fastener is comprised of a pair of said engaging legs disposed in spaced longitudinally extending relationship, at least the outer end portions of said engaging legs formed with an arcuate contour providing a generally circular cylindrical configuration to said outer end portions for facilitating insertion thereof into a circular aperture provided in a mounting member.
Claim 11
Dependent Claim
38 words
The bumper assembly as defined in claim 9, wherein said outer end portions are of an enlarged transverse width in comparison to the inner portions of said legs forming an angularly extending engaging edge defining said engaging means.
