  • 1. Safety Features in Vehicles
  • 2. Learning outcomes
    • Describe the importance of safety features in vehicles
    • Understand the components of safety features in vehicles
    • Labeled the components of safety features in vehicles
  • 3. Introduction
    • Cars today are much safer to travel in than cars ten or twenty years ago.
    • As a result of crash tests, designs have changed and are still changing.
  • 4.
    • What can we do to prevent injuries in car crash?
  • 5. Anti-braking system (ABS)
    • Allows the wheels to continue interacting with the road surface as directed by driver while braking, preventing the wheels from skidding.
  • 6. Crumple Zones
    • Crumple zones were first introduced in 1959.
    • Easily crushed to increase the time interval of impact.
    • In doing so, the force of the collision would be diverted away from the passenger's compartment, thereby keeping him or her from serious injury.
  • 7. Seat belts
    • The seat belt was introduced by Nash Motors in 1949.
    • Seat belts work in the same principle as crumple zones.
    • Help to hold the passengers in their position during collision and prevent them from being thrown forward due to inertia.
  • 8. Airbags
    • Airbags help cushion the impact, reducing your momentum more slowly so that the force is less.
    • Airbags are intended to be used as a supplementary device to the seatbelt.
  • 9. Side Impact Bar
    • Absorbs impact to prevent damage to the car
    • Longer the time of impact and hence will reduce the impulsive force
  • 10. Windscreen
    • Made of shatter-proof glass so that it will not break into pieces easily
    • This will reduce injuries caused by the pieces of glass which scatter during collision
  • 11. Padded Dashboard
    • Increase time interval of collision so that the impulsive force produced is reduced
  • 12. Headrest
    • Prevent the passengers from suffering severe neck injuries
  • 13. Are you ready to play games?
  • 14. What have you learnt today?
