In vehicle energy absorbing bumper mount construction of a type including an elongated housing having top and bottom walls and oppositE side walls and open at front and rear ends, an elongated beam of generally H-shaped cross section located within the housing, and having a web portion spaced between the opposite housing 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, and energy absorbing elastic members bonded to opposite surfaces of the web portion and connected to the housing side walls to hold the H-beam within the housing; the combination of the housing top and bottom walls having rear edges which form part of the housing open rear end; ramp formations being formed on the rear end of at least one of the H-beam top and bottom flanges; longitudinally extending slot means formed in the H-beam web portion; anti-pull-out pin means mounted on and extending transversely between the housing side walls and through said slot means preventing the H-beam from being pulled out of the front end of the housing; and the elastic members being prestressed to hold the pin means engaged with the beam web at the rear end of the slot means, and to hold the ramp formations in contact against the housing top and bottom wall rear edges located adjacent said ramp formations to prevent rattle between the Hbeam and housing when the H-beam is in usual no-load condition.

In vehicle energy absorbing bumper mount construction of a type including an elongated housing having top and bottom walls and oppositE side walls and open at front and rear ends, an elongated beam of generally H-shaped cross section located within the housing, and having a web portion spaced between the opposite housing 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, and energy absorbing elastic members bonded to opposite surfaces of the web portion and connected to the housing side walls to hold the H-beam within the housing; the combination of the housing top and bottom walls having rear edges which form part of the housing open rear end; ramp formations being formed on the rear end of at least one of the H-beam top and bottom flanges; longitudinally extending slot means formed in the H-beam web portion; anti-pull-out pin means mounted on and extending transversely between the housing side walls and through said slot means preventing the H-beam from being pulled out of the front end of the housing; and the elastic members being prestressed to hold the pin means engaged with the beam web at the rear end of the slot means, and to hold the ramp formations in contact against the housing top and bottom wall rear edges located adjacent said ramp formations to prevent rattle between the Hbeam and housing when the H-beam is in usual no-load condition.
Claim 3
Dependent Claim
70 words
The construction defined in claim 1 in which the slot means has top and bottom defining edges; in which the pin means is spaced from said top and bottom slot means edges; and in which the spacing between the top and bottom H-beam flanges and the housing top and bottom walls is approximately equal to said spacing between the pin means and said slot means top and bottom defining edges.
Claim 4
Dependent Claim
45 words
The construction defined in claim 1 in which a pair of transversely aligned openings are formed in the housing side walls adjacent the open front housing end; and in which the pin means is engaged in said openings and is fixed to said side walls.
Claim 5
Dependent Claim
