Seat belts are the most important means of protection in the event of a “side collision†or “after collision†accident. In addition to the front and back drivers, rear seat passengers should also wear seat belts. According to the expert's explanation, when a vehicle crashes or makes an emergency brake at high speed, a large inertia may cause a secondary collision between the occupant in the vehicle and the steering wheel, windshield, etc., resulting in serious injury to the occupant. Seat belts can trap people in their seats, and their cushioning will absorb large amounts of kinetic energy, greatly reducing the degree of injury to the occupants. Seat belts are also more important than airbags. In the absence of seat belts, the airbags that are ejected may even harm passengers. ■collapsed design "The thicker and safer the steel plate," and "the more air bags, the more insurance," is everyone's common understanding in the past, but in fact, the collapse of the modern car design is the latest and most reliable approach to car safety. In many accidents, the car is completely different because of collisions in various directions. However, the passengers in the car are safe and sound. This is totally due to design thinking. Therefore, it is not possible to simply blame the car for the lack of safety. ■Self-protection of the driver in the event of a collision In the event of an impending collision, both sides of the steering wheel should be firmly gripped with both hands, and the abdomen should be forced to squat and the forehead should be buried in the armpit. This is done to avoid vertical forces on the lumbar spine, to reduce the amplitude of the body's swing and to reduce the degree of damage. In particular, both hands hold the steering wheel on both sides to fix the body and reduce the impact of the steering wheel on the chest. ■Buy used cars must consider safety performance Safety standards are constantly updated, and people are reminded that the safety of old cars is often lower than that of new cars. Therefore, the safety performance of the car must be taken into consideration when buying used cars. The old vehicles that were designed and manufactured in the 70s and 80s of the last century are particularly careful. ■Car modification should try to avoid damaging safety facilities Some car modification enthusiasts like to remove the front bumper, side and rear bumper bars and bumper bars, and install beautiful decorations, which may damage the safety of the original car. In addition, some people remove some “unnecessary†equipment in order to reduce the weight of the car, which may lead to a decrease in the ability to prevent “side collision†and “after collision†of the vehicle. Therefore, it is necessary to treat the safety of the original vehicle at the factory with great care.
