The invention discloses a pedestrian lower limb protection device, system and method for a vehicle. The device is arranged above an air inlet grille of a front bumper of the vehicle and located on theinner side of the front bumper of the vehicle, and a tearing line is arranged on the outer side of the front bumper. The device comprises a bumper safety air bag and a safety air bag gas generator, wherein the bumper safety air bag can be unfolded through blasting and tearing the tearing line, and the bumper safety air bag can at least cover the middle of a front bumper, the area above the middleof the front bumper and the front edge area of an engine hood body after being unfolded. After the bumper safety air bag is unfolded, the lower limbs of a person outside the vehicle are almost completely separated from the front bumper and the engine hood body, so that the lower limbs of the person outside the vehicle can be prevented from making direct contact with the front bumper and the engine hood body, and the lower limbs of the person outside the vehicle are greatly protected. Due to the better buffering and energy absorbing effects, the lower limbs of the person outside the vehicle can be better protected.

    本发明公开了一种车辆的行人下肢保护装置、系统及方法,其中,该装置设于车辆的前保险杠进气格栅的上方,且位于车辆的前保险杠的内侧,前保险杠的外侧设有撕裂线,该装置包括保险杠安全气囊和安全气囊气体发生器,保险杠安全气囊能够通过爆破撕裂撕裂线进行展开,保险杠安全气囊展开后能够至少覆盖于前保险杠的中部、前保险杠的中部以上区域以及发动机罩体前缘区域。本发明的保险杠安全气囊展开后几乎完全把车辆外部人员的下肢与前保险杠、发动机罩体隔开,可以防止车辆外部人员的下肢与前保险杠、发动机罩体直接接触,对车辆外部人员的下肢提供了极大的保护作用,并且由于提供了更好的缓冲、吸能作用,可以对车辆外部人员的下肢进行更好的保护。
