| Zusammenfassung: | The invention discloses a layering energy absorption type airbag bumper. The layering energy absorption type airbag bumper comprises a cross beam, an outer bag arranged on the cross beam and provided with a pressure releasing structure and at least one inner bag arranged in an inner cavity of the outer bag. The air pressure of the outer bag is smaller than the air pressure of the inner bags. The inner bags are arranged in the outer bag and can carry out layering energy absorption, and accordingly the acting force instantly generated between a vehicle and a crashed object is reduced so as to improve the protection performance. |
