安全气囊（airbag） Graduation thesis Development and application of airbags Pick to Airbags are located in the front of the car (the front and rear), side side (front and back) and the top three. The Supplemental Inflatable System (SRS) is printed on the outside of the container equipped with the airbag System. The literal translation should be auxiliary Inflatable Restraint System. To reduce the degree of damage caused by a secondary collision of inertia after a collision. As the auxiliary configuration of passive safety, people pay more attention to it. After the automobile collisions with obstacles, referred to as a collision, the occupants collision with the vehicle components, called secondary collision, airbag after a collision, secondary collision before quickly opened a gas cushion, make occupant moves because of its inertia on a cushion of air to soothe crew were hit and absorb collision energy, reduce the damage rate of the crew. Keywords: airbag; Passive safety; The degree of damage Orders to record Pick to the I 1 the introduction 1.1 vehicle safety 1 1.2 benefits of airbags 1 1.3 seat belt and airbag relationship 2 2.

Development and application of airbags 7 The U.S. and European airbags are 7 4.2 development of domestic airbags 5. Dismantle and discard 10 Conclusion 10 Reference 10 Thanks to 11 One, the introduction 1.1 automobile safety When the car speed from frontal crash during more than 30 km/h (collision Angle and motor axis into 30 ° Angle) or side collision, installed in the front or side collision sensors using collision inertia force, detect the collision time, vehicle deceleration impact strength.
