Deployable pedestrian safety device for vehicles

摘要

A frontal structure 300 for a motor vehicle, the frontal structure comprising a deployable air dam 310 covered with a flexible member 316 which is movable from a stowed position to one or more deployed positions, wherein the frontal structure is configured such that when a collision event is detected, predicted or anticipated, said deployable air dam is deployed into a first deployed position in which an edge of the deployable air dam forms the lowest point of the frontal structure and said edge also extends to a point of the frontal structure that is at least as far forward as any other part of the frontal structure of the vehicle in the same vertical plane. Additionally the deployable air dam may have a plurality of operating positions determined by the controller depending on vehicle speed.
