Rear passengers of a car are less protected than those who go from before – 06/05/2019

There is the false belief that the rear seats are safer than the front seats inside a vehicle. This error usually leads to the fatal decision not to use the seat belt during subsequent movements.

The truth is that even with the seat belt set, the pbadengers traveling back are less protected as the driver and the companion.

New frontal crash study in which rear seat pbadengers with seatbelts have been killed or seriously injured more sophisticated restraint systems are needed at the back.

According to a report from the United States Highway Safety Insurance Institute (IIHS), the occupants of the front seats They have greatly benefited from advances in retention systems and airbags, which work together during an accident to maintain a person in an appropriate position and manage the forces exerted on the body.

The occupants of the rear seats, however, they have not benefited from the technology to the same extent.

The IIHS badyzed for the first time the injuries and deaths on the rear seats in 2014. The most important factor was wearing seat belts. However, many adults and children over 9 years old They suffered injuries even when they were tight.

The new study takes a closer look at the specific types of rear seat belt injuries in past accidents.

As soon as a frontal collision begins, the seat-belt safety belts adapt around the occupants, thanks to the integrated devices called contenders. At the same time, the front airbags deploy in a fraction of a second. Depending on the type of collision, the side airbags can also be deployed.

The tight straps and airbags deployed They keep the front occupants away from the steering wheel, dashboard and other structures when the vehicle suddenly stops, even if the force of the impact pushes the structure inwards.

To reduce the risk of chest injuries, these straps have also been force limiters, which allow a little ribbon to unfold before the belt forces become too high.

In the back seaton the other hand, side airbags only protect pbadengers in the event of a side impact, but there are no airbags before, and seat belts usually lack pretensioners and force limiters.

Although seat belts prevent the rear pbadenger from being ejected from the seat during a frontal impact, the absence of a force limiter may serious chest injuries.

To enhance the protection of rear pbadengers, the IIHS offers a series of items to add to the following seats.

Force limiter

This is a small metal bar built into the seatbelt of a belt retractor. Twisting during a shock may release tape before forces increase too much.

Inflatable belt

An inflatable seat belt helps to increase the support surface of the belt in the chest and, therefore, to extend the forces exerted on the torso. In the USA and Europe, some models of Ford and Mercedes-Benz include this unit.

Rear airbag

A front airbag, deployed from the roof, for example, would also cooperate with the seat belt and protect the occupant's head.

For the study, IIHS researchers used two US databases, in which they found 117 shocks in which the occupants of the rear seats are dead or have been seriously injured.

The most common type of injury, found in 22 of the seriously injured occupants and in 17 of the 37 deaths, was thorax.

In many cases of the new study, rear pbadengers suffered more serious injuries than front occupants, suggesting that the rear holds do not work as well as those at the front.
