Airbags

9.3.2.с Knee airbag

• Knee airbag. They are designed for dampening the driver's knee impact on the dashboard in case of a frontal collision. The need for installing this airbag is because that the legroom on the driver's side is quite limited. Due to this, in case of a strong frontal collision, a person can move a considerable distance, which will lead to an impact on the elements of the dashboard and the stiffness bar of the steering column. 

Airbags that are built into seat belts for softening the impact in case of a sudden stop are a promising direction in the development of passive safety system.
