Patent number: 7600780Abstract: To provide a passenger protective device and method that can achieve a stable protective performance even when deploying the airbag from the seat belt, thus allowing for appropriate restraint of the passenger's head. Passenger protective device 1 makes the timing in which the internal pressure of thigh airbag 12 peaks slower than the timing in which the internal pressure of head airbag 11 peaks. In addition, it also makes the timing in which the capacity of thigh airbag 12 reaches the maximum slower than the timing in which the capacity of head airbag 11 reaches the maximum. In this manner, the passenger's head, which moves due to inertial force, is caught by head airbag 11 and head airbag 11 is supported by thigh airbag 12, which is softer than said airbag 11. Therefore, the passenger's head can be caught softly.Type: GrantFiled: April 18, 2006Date of Patent: October 13, 2009Assignee: Nissan Motor Co., Ltd.Inventors: Hideo Tobata, Kouichi Oota, Daisuke Masuda
