Knee airbags are installed in the lower portion of the dashboard, directly in front of the passenger’s knees. When a collision occurs, they inflate to fill the space between the dashboard and the passenger’s lower legs. By reducing the amount of movement of the passenger’s pelvis region and back, these airbags reduce the load on the pelvis support area. This has the positive effect of reducing the load on the passenger’s chest coming from the seat belt. In other words, by restraining the movement of the lower limbs of the passenger’s body, the energy of the passenger’s movement is absorbed in a more efficient manner.
