The main passive safety:

   


Soft protection: passive safety refers to the car after the accident in the vehicle occupant protection, and today the concepts of protection and extends to all the people inside and outside the vehicle or object. International automotive world for passive safety has had very detailed test requirements, so some extent and passive safety is quantifiable. But this different companies had different stressed the sides. Research has shown that, in road traffic accidents, most of the energy is absorbed by the body. In this way under the guidance of vehicle occupant protection when a collision occurs mainly through burst reduction implementation of car-body structure, through a predetermined folds of the permanent deformation, can absorb impacts most. Taking the car's lightweight design trend, "soft protection" does look very economic, but collision based on standardized test results are not able to cover all emergency vehicle accidents, so in extreme safety of these vehicles in accidents or are pending further research.

Hard protection group: the visual impression of the people, as thick as possible hard, the car body steel plate structure the stronger, deformation in case of accidents also becomes smaller, security is naturally high. Indeed, the same size car collisions with each other, "weight" often has advantages. In the eyes of many consumers, Germany cars as the representative of the European cars are "hard protective" representatives.

Equipment: one of the latest progress of the modern automotive industry, is the number of new electronic equipment are effectively applied to vehicle safety systems. To intelligent airbag for cases, in General balloon of Foundation Shang increased has sensor, can detection out seat Shang of crew is children also is adults, they Department good of seat belt and by Department of location is how of height? through collection these data, by computer software analysis and processing control airbag of expansion, makes its play best role, avoid airbag appears no necessary of expansion, to great to improve its security role. Traditional air bag only vehicle occupant protection, new cars will be greater focus on people, vehicles and the integration of environment, so the pedestrian safety will also become one of the factors considered by the automotive designer. Some experts pointed out that future air bag might be along the contour of the hood above the bumper, a collision can provide adult pedestrians, high build with abdominal and hip protection, for both children and adults of short stature with head and chest protection. In addition safety glass: toughened glass and laminated glass combination. Of tempered glass crushing split into many sharp edges when small pieces easily cuts. Laminated glass there are 3 middle tier toughness and adhesion, impact damaged inner and outer still stuck to an intermediate layer, difficult cuts.ADD621 Automotive Compression Gauge
