Embodiment Construction

[0027] A bumper system 20 (attached figure 1 ) includes a beam 21, a mounting bracket 27 and an energy absorber 32. More particularly, the bumper system 20 includes a tubular beam 21 having front, top, bottom and rear walls 22 - 25 and opposing open tubular ends 26 . Mounting brackets 27 are secured to each end 26 of the bumper beam 21 and are also secured to the frame 39 . Both mounting brackets 27 have a U-shaped inner mounting portion 28 fixed to the rear wall 25 of the respective open end 26, and have an integral angle-shaped forming portion 29 extending laterally from the mounting portion 28 around the respective The ends 26 of one end 26 extend outwardly and forwardly until the point where the horn-shaped forming portion 29 is fixed to the front wall 22 of one end 26 . The portion 29 may be fixed to the front or rear surface of the front wall 22, although fixing to the front surface is preferred, for example by welding.

[0028] The corner-shaped portion 29 includes a...

Abstract

A bumper system for vehicles includes a tubular beam having front, top, bottom, and rear walls, and further having open tubular ends. The bumper system further includes a pair of mounting brackets each having a V-shaped mounting section attached to the rear wall of the open tubular ends and having an integral corner-forming section extending from the mounting section laterally around the associated ends and forwardly to a location where the corner-forming section attaches to the front wall of the one end. The corner-forming section includes a resilient portion shaped to flex and absorb energy upon corner impact, and further is adapted to transfer energy directly to the vehicle frame, thus providing efficient and effective energy absorption upon corner impact.

Description

technical field [0001] The present invention contemplates a vehicle bumper system having a bumper beam and components secured to the beam to form a structural corner of the vehicle. Background technique [0002] Vehicle bumper systems typically include a beam and ends secured to the beam to form a pleasingly-looking corner portion, support the vehicle panel, and provide structure for corner impact resistance. However, the additional components add cost, weight replenishment operations, and also dimensional variation and quality control issues. Additionally, each add-on adds hidden costs, such as increased inventory, parts management, floor space requirements, and similar issues. [0003] Integral components are required in bumper systems to save space, reduce part count, and reduce assembly complexity. However, this must be achieved without sacrificing cost, quality, and bumper strength, and without sacrificing the bumper system's ability to pass federal automotive safety ...
