Vehicle Safety Devices That Reduce Impact Force

Automotive safety is the study and practice of design construction equipment and regulation to minimize the occurrence and consequences of traffic collisions involving motor vehicles.

Vehicle safety devices that reduce impact force. One way that today s technology is really helping us is by providing us with many more devices in our vehicles to keep us safe. Some models offer inflatable safety belts in the rear seat that further reduce the force. Crashing and smashing the second animated vehicle s front end is less stiff so it crushes two feet instead of one causing the deceleration to decrease from 30gs to 15 gs. One of the first formal academic studies into improving motor vehicle safety was by cornell aeronautical laboratory of buffalo new york.

The purpose of the airbag is to provide a vehicle occupant with a soft cushioning and restraint during a crash event. An airbag is a vehicle occupant restraint system using a bag designed to inflate extremely quickly then quickly deflate during a collision it consists of the airbag cushion a flexible fabric bag an inflation module and an impact sensor. The first four actually serve the same purpose from the physics standpoint. Features such as crumple zones seat belts and airbags all provide protection if you have a crash however active safety assist technologies which can prevent a crash from occurring are now a significant point of differentiation.

In fact it is the basis for all car safety ratings that guide car buyers in selecting a safe car. Auto safety has come a long way in the last few decades and one of the most effective innovations is the crumple zone also known as a crush zone crumple zones are areas of a vehicle that are designed to deform and crumple in a collision this absorbs some of the energy of the impact preventing it from being transmitted to the occupants. Vehicular safety devices seat belts harnesses inflatable cushions and other devices designed to protect occupants of vehicles from injury in case of accident. Vehicle safety features have come a long way over the years.

They increase the time it takes to stop you that means they decrease the acceleration and therefore the force this way you don t get hit with the same force of a car at 60mph you increase the time it takes to stop a person as opposed to letting for example the dashboard stop you almost instantly you actually aren. Top 10 vehicle safety devices you need to be aware of sometimes we wonder if technology is hurting more than helping us and in some cases it may be. After the pretensioners tighten it force limiters let the belt play back out a little to reduce the force. A seat belt is a strap that fastens a rider to a moving vehicle and prevents him from being thrown out or against the interior of the vehicle during sudden stops.

Extending the time of impact is the basis for many of the ideas about keeping people safe in crashes list three applications in vehicle or highway safety.
