Abstract
The invention relates to a bumper for a vehicle body having two side members (11, 12), said bumper consisting of a bumper bracket (13) extending over the width of the body, with two deformation members (14, 15) projecting at right angles from the back at a distance from one another, said members being integral with bumper bracket (13) and being connectable by bolt connections (20) with side members (11, 12). The deformation members (14, 15) are more resistant to deformation than bumper bracket (13), so that they deform to absorb additional energy only when the ability of bumper bracket (13) to deform is exhausted.
Claims28
A bumper for a vehicle body having two side members, said bumper having a bumper bracket extending over the width of the vehicle body and two deformation members mounted at a distance from one another on a back side of the bumper bracket facing the vehicle body, said deformation members being made more resistant to deformation than the bumper bracket so that they deform only after the bumper bracket has deformed,
- wherein the bumper bracket is assembled from half shells which abut one another within a separating plane that extends essentially horizontally in a mounted position and which are connected to one another by flanges, and wherein the half shells each have half shell wall parts facing the vehicle body which form the two deformation members, said half shell wall parts being made in one piece with the half shells and projecting transversely therefrom, and said half shell wall parts forming hollow bodies integral with the bumper bracket and resistant to deformation when in the mounted position.
A bumper for a vehicle body having two side members, said bumper having a one-piece bumper bracket extending over the width of the vehicle body and two one-piece deformation members mounted at a distance from one another on a back side of the bumper bracket facing the vehicle body, said deformation members being made more resistant to deformation than the bumper bracket so that they do not deform to absorb additional energy until the bumper bracket has fully deformed, wherein the bumper bracket and the deformation members are each made as extrusion-molded profiles and wherein the extrusion-molded profiles are connected directly together by one of bolting, riveting, gluing, or welding.
A bumper for a vehicle body having two side members, said bumper having a bumper bracket extending over the width of the vehicle body and two deformation members mounted at a distance from one another on a back side of the bumper bracket facing the vehicle body, said deformation members being made more resistant to deformation than the bumper bracket so that they do not deform to absorb additional energy until the bumper bracket has fully deformed, wherein the bumper bracket and the deformation members are each made as extrusion-molded profiles and wherein the extrusion-molded profiles are connected together by one of bolting, riveting, gluing, or welding, wherein the bumper bracket is made in a middle area as a closed box profile and is formed in end areas as a U-profile that opens toward the vehicle body.
A bumper for a vehicle body having two side members, said bumper having a bumper bracket extending over the width of the vehicle body and two deformation members mounted at a distance from one another on a back side of the bumper bracket facing the vehicle body, said deformation members being made more resistant to deformation than the bumper bracket so that they do not deform to absorb additional energy until the bumper bracket has fully deformed, wherein the bumper bracket and the deformation members are each made as extrusion-molded profiles and wherein the extrusion-molded profiles are connected together by one of bolting, riveting, gluing, or welding, wherein the profiles are provided with reinforcing ribs aligned horizontally in a mounted position, said ribs abutting two opposite profile walls of the profiles.
