Bumper
From Wikipedia, the free encyclopedia
- For other uses, see Bumper (disambiguation).
A bumper is a part of a automobile designed to allow one vehicle to impact with another and to withstand that collision without severe damage to the vehicle's frame. Brush guards, push bars, etc. were added "after-market" to bumpers of automobiles, pickups, trucks, and utility vehicles since at least the 1920s to provide additional protection to the vehicle. While bumpers were originally made of heavy steel, in later years they have been constructed of rubber, plastic, or painted light metal leaving them susceptible to damage from even minimal contact. For the most part, these vehicles cannot push, or be pushed by, another vehicle. An entire after-market industry has developed which now produces various guards to protect these vulnerable modern bumpers.
The fun of bumping one car into another led to the creation of bumper cars at amusement parks and carnivals. These small cars are designed to fit one or at most two people and crashed into each other consistently.
[edit] Legal issues
In many jurisdictions, bumpers are legally required on all vehicles for safety reasons. The height and placement of bumpers may be legally specified as well, to ensure that when vehicles of different heights are in an accident, that the smaller vehicle will not slide under the larger vehicle, particularly in collisions with semi-trailer trucks.
