Take a look at the following picture.
In this the front part of the seat is attached directly to the base.
The back of the seat rests on an iron channel.
In the event of an accident, this arrangement works because the back of the seat tilts down.

How it works

    ⇒  Let’s understand this in simple language.

 
    ⇒   When a speeding vehicle crashes, the occupants of the vehicle are usually thrown forward. Why, flat seats can’t provide us with any assistance  to keep us from falling during an accident.

    ⇒   An accident happens first to the vehicle. After that, accident  happens to the people in the vehicle

    

⇒  During this accident, if the angle of the back of this seat can be changed, people can avoid the g by 60%. Also the severity of the accident can be thrown effect reduced to a great extent.

in this system the back of the seat rests on a clamp. A pressure spring pushes the seat clump. A lock on the other side keeps this pressure clump stable. When the vehicle is involved in an accident, this lock is opened by a cable. Then the pressure spring pushes the seat clump forward.

As soon as the seat clamp was pushed, the seat fell down 

this will saves from the accidents
when accident occurs this will instntly changes the angle of the seat for
