Science Safety Features of Car

  • Head Rest

    Head Rest
    Benjamin Katz invented the head rest for cars in 1921. Head rests decrease the harm caused by whiplash when the driver is faced with rear-end collisions. The Headrest applies to Newton's 1st and 2nd Law.

  • Padded Dashboard

    Padded Dashboard
    Preston Tucker invented the padded dashboard in 1948. The padding in the dashboard is designed to decrease face and chest injuries to the driver when faced with front on collisions it also intends cushion the impact.This Safety feature relates to the 1st & 2nd of the Newton's Laws.

  • Crumple Zone

    Crumple Zone
    The crumple zone of a car was invented in 1952 by Bela Barenyi then was first used in cars in 1959. The Crumple zone of a car is an area that is built into cars that are designed to collapse, crumple and absorb kinetic energy released when faced with a collision to protect the driver. The Crumple Zone applies to Newton's 1st, 2nd & 3rd Law.

  • Seatbelt (3-Point)

    Seatbelt (3-Point)
    The 3 point Seat Belt was invented by Nils Bohlin in 1959 and was introduced into cars in 1963. The 3 point seat belt was improved from the 2 point seatbelt which only supported the driver's thighs/hips whereas the 3 point seat belt has three points and restrains the driver at the hips and across the shoulder which stops the drivers top half of their body to fly into the steering wheel and cause serious back injuries or even death. The 3 point Seatbelt applies to Newton's 1st Law.

  • Side Airbags

    Side Airbags
    The Side Airbag was invented in 1989. How it works: It inflates when the driver is faced with a side-on collision. It can protect both the head and upper body. Usually the upper body-protecting airbag is built into the side of the seat. This side airbag prevents the driver from getting severe head and upper body injuries.The Side Airbag applies to Newton's 1st, 2nd & 3rd Law.

  • SRS Airbag

    SRS Airbag
    The SRS Airbag was invented in 1989. It is designed to increase the restraint on a seatbelt in a collision, not being the only restraining system. The SRS involves several inflatable airbags which can be inflated when the driver is faced with a front-on collision, where the driver’s head and upper body could come in contact with part of the vehicle. The regular SRS airbag is situated inside the driver's steering wheel. The SRS Airbag applies to Newton's 1st, 2nd & 3rd Law.

  • Brake Assist

    Brake Assist
    The Brake Assist System was invented in 1996 senses attempted panic braking focused on the force that is put on the brake pedal and how quickly the driver is stepping on the pedal. When the Brake Assist System senses rapid braking, it will increase more pressure to the brake so this means that The System prevents crashes majorly. The Brake Assist System applies to Newton's 2nd Law.

  • Curtain Airbags

    Curtain Airbags
    The Curtain Airbag was invented 1998. Curtain airbags fill the area between the driver and the headliner and side windows. They help defend the driver when faced with a side-on collision or a rollover incident it also prevents the drivers head from smashing through the side window and cause the driver to have serious head injuries even death. This type of Airbag applies to Newton's 1st, 2nd & 3rd Laws.
