Embodiment Construction

[0015] Please refer to FIGS. 1 to 3 , which illustrate a hinge device 10 intended to pivotally connect a rear edge of a hood 11 to a vehicle body frame (not shown). It will be appreciated that the hood 11 is pivotally mounted in a conventional manner by means of two hinge means (only one being shown), located on the right and left sides of the hood respectively.

[0016] Each hinge device 10 is associated with a lifting actuator (not shown). In this embodiment, each hinge device 10 comprises three metal pieces (also referred to as hinge parts), the lower piece 12 is mounted on a part of the vehicle body frame, the upper piece 13 is mounted on the bonnet 11, and the middle piece 14 connects the lower and upper pieces. Tablets 12, 13.

[0017] The rear end of the lower piece 12 has an upwardly protruding portion 15 which is pivotally mounted to the rear end of the middle piece 14 . The free end of the middle piece 14 has a stud 16 extending transversely.

[0018] The front en...

Abstract

A hinge mechanism 10 to lift the rear edge of a bonnet 11 of a motor vehicle comprises an upper leaf 13 connected to the bonnet 11, a lower leaf 12 connected to the body structure of the vehicle and a middle leaf 14 connected to the upper leaf 13 and the lower leaf 12. The middle leaf 14 is connected to the upper leaf 13 by means of a stud 16 and a slot 17 connection so as to limit movement of the bonnet from a normal position to a deployed position under an upward force exerted by a lift actuator. The stud 16 and slot 17 connection is provided with a resiliently deformable element 30 arranged at the end of the slot for dissipating impact energy of the stud 16 against the slot 17 during the upward force.

Description

technical field [0001] The present invention relates to a hinge arrangement for lifting the rear edge of a motor vehicle hood or hood to enhance pedestrian safety. Background technique [0002] Various proposed hinge arrangements for hood-to-body frame assembly rely on at least one lift actuator to raise the rear edge of the hood from its normal closed position to a partially raised position if a collision with a pedestrian is detected Location. Such hinge arrangements generally have a first mode of operation in which the front edge of the hood is lifted in the normal manner by the hinge about a pivot axis defined by the rear side of the hood, and a second mode of operation in which the rear edge of the hood is lifted by The actuator is raised. One type of known hinge arrangement provides upward movement of the hood through cooperating bolts and slots arranged on the hinge. See for example British Patent No. GB2410924 which shows a hinge arrangement for pivotally mounting...
