Automobile bumper has gas-filled airbag chamber coupled to second airbag chamber inflated by displaced gas upon frontal impact

摘要

The bumper (5) has at least one gas-filled airbag chamber (4), coupled to a second airbag chamber (8), positioned below the bumper in the vicinity of the front spoiler (7) of the automobile (1), which is normally collapsed in a folded state and is inflated by the gas displaced from the first airbag chamber in the case of a frontal impact. A series of gas-filled airbag chambers can lie next to one another along the length of the bumper, covered by an elastic skin defining the bumper contour.
