Design and Analysis of the Human Airbag

airbag, the rate of impact force increase and attenuation is smaller than that without the
airbag, and the time period of impact is extended from instantaneous to about 0.1 s. The
analysis shows that the air bag designed in this paper can greatly reduce the impact force
of the femur and protect the human body.

5 The Results of the Analysis
An airbag for hip protection is designed in this paper, and the dynamic response of femur
with airbag is calculated by finite element simulation. The results show that the impact
of the femur can be effectively reduced when the human body falls sideways, and the
impact force can be reduced by 94%, which verifies the feasibility and effectiveness of
the designed airbag.
