[edit] Crumble Zone
- The crumple zone increases the reaction time of collision during an accident.
- This causes the impulsive force to be reduced and hence reduces the risk of injuries.
[edit] Seat Belt
Prevent the driver and passengers from being flung forward or thrown out of the car during an emergency break.
[edit] Airbag
The inflated airbag during an accident acts as a cushion to lessen the impact when the driver flings forward hitting the steering wheel or dashboard.
[edit] Head Rest
Reduce neck injury when driver and passengers are thrown backwards when the car is banged from backward.
[edit] Windscreen
Shatter-proof glass is used so that it will not break into small pieces when broken. This may reduce injuries caused by scattered glass.
[edit] Padded Dashboard
Cover with soft material. This may increases the reaction time and hence reduce the impulsive force when passenger knocking on it in accident.
[edit] Collapsible Steering Columns
The steering will swing away from driver’s chest during collision. This may reduce the impulsive force acting on the driver.
[edit] Anti-lock Braking System (ABS)
Prevent the wheels from locking when brake applied suddenly by adjusting the pressure of the brake fluid. This can prevents the car from skidding.
[edit] Bumper
Made of elastic material so that it can increases the reaction time and hence reduces the impulsive force caused by collision.
[edit] Passenger Safety Cell
- The body of the car is made from strong, rigid stell cage.
- This may prevent the car from collapsing on the passengers during a car crash.
