A vehicle Bumper system

摘要

A pedestrian protection apparatus for a vehicle and in particular for a vehicle with high ground clearance such as a truck is disclosed. The apparatus includes a bumper member (16) mounted to a vehicle (17), a linkage (38), a stiffener (28), an extendible cross-member means (26), and an actuation means (40). The extendible cross-member means (26) is mounted on the stiffener (28) which in turn is mounted at each end by a first linkage and a second linkage (36) and (38) respectively. The pedestrian protection apparatus extends out from under the vehicle (17) at speeds approximately greater than a pre-determined speed in order to prevent a pedestrian from going under the vehicle (17) in the event of a collision.
