Vehicle Bumpers With Collapsible Parts
US Patent:
4333674, Jun 8, 1982
Filed:
Feb 14, 1980
Appl. No.:
6/121325
Inventors:
Carl F. Buettner - St. Louis MO
John S. Hill - Joplin MO
John S. Hill - Joplin MO
International Classification:
B60R 1900
US Classification:
293120
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.
