Bumpers are usually the first part of a car that connects in a collision. They absorb most of the impact. They are made to protect other parts of the vehicle, not the driver or passengers.
For along time bumpers have been made to protect the bodywork of a car in the event of low speed collision, such as at stops or traffic lights. Bumpers are relatively cheap compared to body sections of cars, and often prevent a lot of body damage. In a high speed collision it doesn't matter whether you have bumpers or not, lots of bodywork will be wrecked.
The plastic rings around graduated cylinders are bumpers designed to protect the glass cylinder from damage if it is accidentally knocked or dropped. They help to absorb impact and prevent the glass from breaking.
To absorb some of the energy from a low impact accident.
in 1941 Will Smith and Elvis Presley invented the impact driver
Areas where the structure in a vehicle is allowed to collapse and absorb the kinetic energy of an impact and reduce the kinetic energy transfered to the people in the vehicle. Normally it located in front portion of a vehicle for when you run into something or are hit head on. The original crumple zone was a section of the steering column that was cut and replaced with a tube of metal mesh. This allowed the steering column to collapse instead of thrusting back with the front axle and killing the driver. Later the bumpers were mounted on springs instead of rigid onto the frame or structure of the vehicle. Also known as the 35 mile per hour system. Anything under 35 was able to be absorbed by the bumpers. Then the front structural crumple zone was introduced that allowed the impacts greater then 35 miles per hour to be more surivable.

There are sensors in the bumpers and frame. An impact of 5 miles per hour or above will deploy them.jd
A type of bumper made out of soft flexible plastic that deforms slightly at low speed impact and has a foam backing - this will stop the bumper cracking
