Abstract
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 is comprised of a frangible and collapsible or otherwise deformable end portion made of materials such as plastic impregnated fiber glass or rubberlike materials which extend in front of one or both of the vehicle wheels, which end portions may be attached to reduced length metal or wood bumpers and fracture and breakoff or distort on impact but do not bend into contact with other parts of the vehicle.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
119 words
A safety bumper construction for trucks and other like vehicles having body portions and spaced front and rear wheel assemblies comprising a first member which is approximately as long as the width of the vehicle body on which it is to be installed, and a second member adapted to be mounted on the first member, said second member being longer than the first member and having end portions which extend beyond at least one end thereof and in front of at least one of said vehicle wheel assemblies, said second member being formed of a relatively rigid but frangible material whereby the endwardly projecting portion thereof is much more likely on impact to fracture and break-off than to bend.
Claim 2
Dependent Claim
119 words
A safety bumper construction for trucks and other like vehicles having body portions and spaced front and rear wheel assemblies comprising a first member which is approximately as long as the width of the vehicle body on which it is to be installed, and a second member adapted to be mounted on the first member, said second member being longer than the first member and having end portions which extend beyond at least one end thereof and in front of at least one of said vehicle wheel assemblies, said second member being formed of a relatively rigid but frangible material whereby the endwardly projecting portion thereof is much more likely on impact to fracture and break-off than to bend.
Claim 3
Dependent Claim
110 words
A safety bumper for vehicles comprising a member having first and second connected portions, said first portion having opposite ends, being constructed of a relatively rigid material and being substantially shorter than the width of the vehicle on which it is to be installed, said second portion including a central section overlaying the first portion and having opposite end sections attached to the central section and extending endwardly beyond the respective opposite ends thereof, said second portion being formed of a relatively rigid but frangible material which on impact is more likely to break-off adjacent to at least one of the opposite ends of the first portion than to bend.
Claim 4
Dependent Claim
110 words
A safety bumper for vehicles comprising a member having first and second connected portions, said first portion having opposite ends, being constructed of a relatively rigid material and being substantially shorter than the width of the vehicle on which it is to be installed, said second portion including a central section overlaying the first portion and having opposite end sections attached to the central section and extending endwardly beyond the respective opposite ends thereof, said second portion being formed of a relatively rigid but frangible material which on impact is more likely to break-off adjacent to at least one of the opposite ends of the first portion than to bend.
