Abstract: A pedestrian safety device for automotive vehicles with a deployable hood consists of a pedestrian safety module beneath the leading edge of the hood, and a hinge assembly at the trailing edge of the hood. The hood is latched to the module. In case of a pedestrian impact at the leading edge of the hood the module is mechanically released to rotate, so that the hood is lowered at the leading edge. Simultaneously the rotational impulse of the hood is used to uplift the trailing edge of the hood. A two bar link at the rear hinge assembly is released by the hood impulse and enables uplifting of the trailing edge of the hood, and locks the hood in a deployed position.

Abstract: A vehicle bonnet assembly has a bonnet hinged to the vehicle body by means of a hinge assembly including a first link pivoted intermediate of its extremities to the vehicle body and second and third links pivoted at one end, each to a different end of the first link, and at their other ends to the bonnet, the links being arranged such that when the bonnet is closed, the bonnet will move rearwardly upon an impact above a predetermined magnitude being applied to the leading edge of the bonnet, the links pivoting to lift the trailing edge of the bonnet, the bonnet pivoting between an open and closed position about the pivotal connection of the first link to the vehicle body.
