Automobile head restraints are essential? Absolutely Yes and be used respecting some important rules! Gone are the days in which to save many motorists did not maintain this useful accessory, dismiss a priori the undisputed usefulness. A hypothesis now set aside by the same manufacturers that offer the modern car headrest as standard for all occupants on most models in price list.

Serve really?
Of course, even if what is perplexing is that still a mysterious object for too many motorists. There are a few to believe the headrest a simple decorative element, but is not so! In fact play a vital role for the passive safety and their correct use is capable of preventing serious injury.

Ammansiscono the “whiplash”
All we have heard of and some of you probably have also experienced the evil effects. Physically it is an unnatural movement of the head, a move beyond the limit of allowed. The situation the protagonist in rear-end collisions. When a vehicle is hit on the passenger’s body undergoes a force that pushes you forward violently. For inertia, however, retains its natural leaning backwards position. Subsequently the head “back office”, projected forward at a speed higher than the rest of the body.

The harm of “whiplash”
Fortunately, in most cases the impact is not as violent by tearing muscle fibres and consequences are “bound” (so to speak) to stretch the muscles and ligaments. Pain and recovery days so make sure you are!

We use the headrest?
So then comes into play this useful security system (we learn to know him as such). But we know better appreciation of the virtues? Here’s some advice. First “regoliamolo” in height so that the upper is at least 5 cm above the ear. The same regulation should also cover the “forward-backward”. We do so in such a way that the distance of the head restraint is not more than 6 cm. Only in this way we will avoid that in the event of impact, the travel of the head backwards is excessive. Also the location of the back and head are important. Try to adjust the seat so as to stand upright with her back so as not to distanziarvi too precious headrest!!!!

Situations where they are more likely to rear-end collisions (and consequent flicks) we next intersection (stop or traffic lights) and more generally in cases of poor visibility. Used with the well-lit wisdom of car as headlights, fog lights, arrows and, if possible, avoid sudden braking.
