The airbag spring plays an important role in the car. It is mainly used to connect the main airbag (the airbag on the steering wheel) to the airbag harness. It is actually a section of wire harness installed inside the steering wheel, located at the position of the horn. The main airbag rotates with the steering wheel, so the spring needs to be wrapped around the steering wheel and rotate with the steering wheel. When connecting the harness, a certain margin needs to be left to ensure that the steering wheel is not pulled apart when it is turned to the limit. The safety of the car is divided into active safety and passive safety. Active safety refers to the ability of the car to avoid accidents, while passive safety refers to the ability of the car to protect the driver when danger occurs. This is mainly reflected in seat belts, anti-collision body and airbag protection system.

The role of the airbag spring is to ensure that the driver can be fully protected when the car collides. In the passive safety system, the airbag is an important component. The airbag will inflate quickly during a collision to form a soft airbag to reduce the damage to the driver caused by the collision. The airbag spring is a component that connects the main airbag and the airbag harness. Its function is to ensure that the main airbag can work properly.

The normal operation of the car airbag requires the support of the airbag spring. It needs to leave a certain margin when connecting the harness to ensure that the steering wheel is not broken when it is turned to the limit. The car spring is generally installed inside the steering wheel, located at the horn position. Since the main airbag rotates with the steering wheel, the spring needs to rotate with the steering wheel to ensure that the airbag can be quickly inflated when needed.
