Safety features in vehicles

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