Abstract

Abstract A vehicle bumper mounting construction formed of a generally elongated box-like metal housing member enclosing a portion of an elongated beam member generally H-shaped in cross section. A pair of rubber pads having parallel surfaces are bonded on one surface of each pad to the web of the H-beam member on either side thereof. A metal plate is bonded to the other side of each pad. The H-beam and pads are secured within the housing member and the metal plate on each pad is secured to a side wall of the housing. The metal housing is provided with means for mounting the assembly on an automobile, and the H-beam is provided with a mounting flange for attaching the automobile bumper to the assembly. The rubber pads are pre-loaded to hold the components against rattling in the at-rest or normal position of the mount components. Impact energy applied to the bumper is absorbed by the construction by deflection of the H-beam placing shear stress on the rubber pads.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 210 words
In vehicle energy absorbing bumper mount construction of a type including an elongated metal housing having top and bottom walls and opposite side walls and open at front and rear ends, an elongated metal bumper 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 front portion of the H-beam extending outward from the housing interior from the front open end of the housing, the rear end of the H-beam being located adjacent to the rear open end of the housing, energy absorbing rubber pad means connected to the metal housing and to opposite surfaces of the metal H-beam web to hold the H-beam within the housing; the combination of rubber pad means composed of rubber pads and metal plates at one surface of each pad, and a hot bond connection between each metal plate and said one surface of each pad, and a hot bond connection between a second surface of each pad opposite said one surface and the matel H-beam web; and means interengaged between the metal plates and metal housing locking the plates in fixed assembled position within the housing.
Claim 2
Dependent Claim 210 words
In vehicle energy absorbing bumper mount construction of a type including an elongated metal housing having top and bottom walls and opposite side walls and open at front and rear ends, an elongated metal bumper 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 front portion of the H-beam extending outward from the housing interior from the front open end of the housing, the rear end of the H-beam being located adjacent to the rear open end of the housing, energy absorbing rubber pad means connected to the metal housing and to opposite surfaces of the metal H-beam web to hold the H-beam within the housing; the combination of rubber pad means composed of rubber pads and metal plates at one surface of each pad, and a hot bond connection between each metal plate and said one surface of each pad, and a hot bond connection between a second surface of each pad opposite said one surface and the matel H-beam web; and means interengaged between the metal plates and metal housing locking the plates in fixed assembled position within the housing.
Claim 3
Dependent Claim 61 words
The construction defined in claim 1 in which the means interengaged between the plates and housing include ears formed on one of the plates and housing walls, ear receiving openings formed in the other of the plates and housing walls, and the ears extending through said openings and being clinched to lock the plates in fixed assembled position within the housing.
Claim 4
Dependent Claim 26 words
The construction defined in claim 2 in which the ears are formed on the plates, and in which the openings are formed in the housing walls.
Claim 5
Dependent Claim 28 words
The construction defined in claim 3 in which the metal H-beam web extends vertically and in which the openings are formed in opposite side walls of the housing.
Claim 6
Dependent Claim 54 words
The construction defined in claim 4 in which the housing includes a channel-shaped member forming the top, bottom and one side wall of the housing; in which a mounting plate member is secured to the channel member; and in which the ear-receiving openings are formed in the mounting plate member and channel side wall.
Claim 7
Dependent Claim 73 words
The construction defined in claim 1 in which ramp-like anti-pull-out formations are formed at the front and rear end portions of the top and bottom housing walls; in which similar ramp-like anti-pull-out formations also are formed at the top and bottom portions of the H-beam adjacent the housing formations; and in which the energy absorbing rubber pad means are preloaded when the plates thereof are locked in fixed assembled position within the housing.
Claim 8
Dependent Claim 37 words
The construction defined in claim 6 in which anti-rattle pads are located between adjacent ramp-like formations on the housing and H-beam; and in which the anti-rattle pads are held under compression by the pre-loaded rubber pad means.
