ABSTRACT:
This invention relates to vehicle bumpers and more particularly to vehicle bumpers with frangible or resiliently collapsible parts which break-away or distort on impact to minimize the loss of control which often occurs when metal and other more usual types of bumpers bend on impact and puncture tires or produce undesirable braking action or become entangled with other parts of the vehicle. This invention is characterized by a vehicle bumper construction wherein at least a portion thereof, and preferably the entire device, is of one-piece construction and is comprised of a frangible and collapsible or otherwise deformable member including a central portion and one or more integral end portions all made of a material such as plastic impregnated fiber glass or rubber-like materials, which end portions extend in front of one or both of the vehicle wheels and fracture and breakoff on impact rather than bend.
