Safety Cage
Purpose during a crash:
The safety cage is the area of a car that surrounds the passenger and is strengthened or stiffened to protect the passenger during a car crash. It combines with the crumple zone; the crumple zone crumples and the safety cage makes sure the passenger is not crushed. The safety cage consists of floor to roof pillars, side impact bars and a floor and roof structures. The safety cage is also important because it if the main structure of the vehicle to which all other components are attached.
There are many different types of frames, for example the ladder frame resembles a ladder and is one of the oldest and simplest designs. Another example is the space frame (a three-dimensional skeletal frame of tubes), which the suspension, engine, and body panels are attached to.
Safety cages protect the passenger in a roll over situations by having strong roofing pillars; they strengthen the cabin section and keep the car’s shape in a frontal crash to protect the driver and the passenger’s space. They also keep the car doors closed and able to open after crash, for easy access to any injured passengers. Safety ages are very important in smaller cars that do not have a crumple zone because otherwise the passenger would be crushed.

Physics:
According to Newton’s third law for every action, there is an equal and opposite reaction. Therefore in the event of a car crash the car will absorb the force of the object hit. If the car is not strong enough to withstand the opposite force it will crumple in on the passenger, the safety cage prevents this from happening by giving the car more strength.

Developments:
Until the 1930s: Virtually every vehicle had a structural frame, separate from the car's body. This construction design is known as body on frame.
January 23rd 1951: The first safety cell was patented in a car body by Daimler-Benz AG.
Modern Cars: Safety cages are now widely used in cars, nearly all cars have a unibody construction meaning their chassis and bodywork have been integrated into one another. Nearly all trucks, buses and pickup trucks continue to use a separate frame as their chassis.
