Research output: Patent


A safety device for a bonnet acts to raise the bonnet (10) of a vehicle in the event of a collision with a pedestrian. The device comprises a first arm (L1) for pivotal connection (P1) to the bonnet, a second arm (L2) for pivotal connection (P2) to a part of the body structure (11), a third pivot means (P3) connecting the first and second arms forming a linkage, and a spring means (12) to urge the first and second arms between a collapsed and raised position. Preferably, when moving from the collapsed to the raised position the third pivot means moves from one side of a plane (X) extending between the first and second pivot means to the opposite side; the angle between the arms going from less than 90{ to more. A travel limit means (13) may be provided to limit movement of the arms when in the extended position. Ideally, a third (L3) and fourth (L4 ) arm are provided attached to the first and second pivot means respectively; wherein the third and fourth arms are longer than the first and second.
