Crushed profile bumper and method for producing
View Patent ↗A formed beam for use as a vehicle bumper having an elongated body exhibiting front and rear opposing surfaces and top and bottom surfaces interconnecting the front and rear surfaces, such that the beam defines a swept shape between first and second opposite ends. A plurality of spaced apart and transverse extending beads are formed upon the top extending surface of said beam and at least a portion of one of the front and rear surfaces are inwardly displaced relative to each other and during formation of an arcuate profile to the beam, and such that the front and rear surfaces exhibit at least partially non-parallel surfaces.
1. A formed beam for use as a vehicle bumper, comprising:
an elongated body having front and rear opposing surfaces, top and bottom surfaces interconnecting said front and rear surfaces and defining a swept shape between first and second opposite ends;
said front surfaces corresponding with said first and second ends being displaced rearwardly in a direction towards said rear surfaces, reducing a cross-sectional area associated with each of said first and second ends such that said bumper, upon being secured to a vehicle front end, more closely aligns with corresponding vehicle fascia components; and
at least a portion of one of said front and rear surfaces being inwardly displaced in a direction towards an opposing surface, during formation of said beam, said front and rear surfaces exhibiting at least one of non-parallel surfaces and non-constant radii at certain locations.
2. The beam as described in claim 1 , said roll-formed beam exhibiting an extending and central planar section separating upper and lower three-dimensional and tubular shaped sections.
3. The beam as described in claim 1 , further comprising first and second inwardly displaced mounting locations formed within said rear surface and proximate said first and second ends.
4. The beam as described in claim 1 , said beam exhibiting a specified shape and size and being constructed of a steel exhibiting at least a 100 ksi rating.
5. A formed beam for use as a vehicle bumper, comprising:
an elongated body having front and rear opposing surfaces, top and bottom surfaces interconnecting said front and rear surfaces and such that said beam defines a swept shape between first and second opposite ends, said body further comprising a structural steel exhibiting at least a 100 ksi rating;
a plurality of spaced apart and transverse extending beads being formed upon said top extending surface of said beam; and
at least a portion of one of said front and rear surfaces being inwardly displaced in a direction towards an opposing surface, during formation of said beam, and such that said front and rear surfaces exhibit at least partially non-parallel surfaces.
6. A formed beam for use with a vehicle bumper, comprising:
an elongated body having front and rear opposing surfaces, top and bottom surfaces interconnecting said front and rear surfaces and defining a swept shape between first and second opposite ends;
a plurality of spaced apart and transverse extending beads being formed upon a selected extending surface of said beam; and
at least a portion of one of said front and rear surfaces being inwardly displaced in a direction towards an opposing surface, during formation of said beam, said front and rear surfaces exhibiting at least one of non-parallel surfaces and non-constant radii at certain locations.
