Automobile safety belt can stretch and retract when the safety belt tension

The wrinkle region is to play a role of buffering area. The crease area is the automobile front and rear is relatively easy to fold region. The car hit the not suddenly stop obstacles, but by collapsing (like empty can absorb part of impact force.). The car compartment is relatively strong, so as not to squeeze in the passengers. It will continue to move to the front of the car a short, into obstacles. Of course, only in the car together with your exercise (that is to say, the safety belt shall be fixed in your chair), wrinkle area can provide protection for your. The safety belt of the most simple (some roller coasters use the safety belt) is composed of by a long strap bolts on the body. The safety belt will always be you closely tied to the chair, it would be very safe, but not very comfortable.

Automobile safety belt can stretch and retract when the safety belt tension, your body can easily rake. But in the crash, safety belt will suddenly tightened and will you firmly fixed.

In the safety belt system in typical, safety belt are connected with a retractor, a core component of retractor is the scroll, which is connected with a safety belt. The retractor, a spring to provide a rotating force (or torque) as a scroll. It will rotate to reel, rolled up any slack in the safety belt. When you pull the safety belt, a reel to rotate counterclockwise, and the spring connected along the same direction of rotation. So, the rotation of the reel on the torsion spring. Because the spring to restore to the original state, so it can resist a twisting motion. If you release the safety belt, spring will tighten, and clockwise rotation of reel, until the safety belt tensioner.

Everyone has a heart, if the heart stops beating and the life will disappear.Cars are no exception,obd code readers is the heart of the car,therefore, quality is good and bad, directly affects the car's performance and service life.
