Safety Mechanisms Installed In Cars

Seat Belts

In the event of a crash, seat belts are designed to keep you inside the vehicle. They also reduce the risk that you will collide with the steering wheel, dashboard, or windshield.

Safety-belt features While the seatbelt is arguably the single most important piece of safety equipment, enhanced features help seatbelts do their job more effectively. Seatbelt pre-tensioners instantly retract the belts to take up slack during a frontal impact. This also helps position occupants properly to take full advantage of a deploying airbag. Force limiters, a companion feature to pre-tensioners, manage the force that the shoulder belt builds upon the occupant’s chest. After the pre-tensioners tighten it, force limiters let the belt playback out a little to reduce the force.

Air Bags

Front airbags have been standard on all new cars since 1998 and light trucks since 1999. Most vehicles had them even before then. Crash sensors connected to an onboard computer detect a frontal collision and trigger the bags. The bags inflate in a few milliseconds then immediately start deflating.

Most airbag systems now detect the presence, weight, and seat position for the driver and front passenger, and deactivate or de-power front airbags as appropriate to minimize the chance of injury to drivers positioned close to the wheel, occupants or children. Side airbags.

Side airbags are fairly small cushions that pop out of the door trim or the side of the seatback. They help protect the torso, but most aren’t effective in protecting the head. Nearly all new models today also include additional “side curtain” bags that deploy from above the windows and cover both front and rear side windows to prevent occupants from hitting their heads and to shield them from flying debris. A curtain bag often also stays ‘inflated’ longer in most cases to also keep people from being ejected during a rollover or a high-speed side crash. The better head-protection systems deploy the side-curtain bags if the system detects that the vehicle is beginning to roll over.

Antilock Brake System (ABS)

Before antilock brakes came along, it was all too easy to lock up the wheels during hard braking. Sliding the front tires makes it impossible to steer, particularly on slippery surfaces. ABS prevents this from happening by using sensors at each wheel and a computer that maximizes braking action at each individual wheel to prevent lock- up.
