Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
147 words
A bumper for vehicles comprising: a molded plastic rim member formed from setting of molten material as a result of a molding operation, a foamed urethane form positioned within said rim member to absorb shocks to which the bumper may be subjected, and a reinforcement member to reinforce the bumper positioned rearwardly of said foamed urethane form and affixed to said rim member when the latter is formed, said reinforcement member having two flanges which define a groove therebetween, the upper portions of said two flanges having projections which form a narrowed portion in said groove, at least one of said two flanges defining at least one aperture which connects to said groove for passing molten material therethrough and into said groove to form said rim member, whereby said rim member and said reinforcement member are integrally fixed to each other upon setting of the molten material.
