Hinge mechanism

The invention relates to a hinge mechanism (16) for a bonnet (12) of a vehicle (10). The hinge mechanism comprises: - a first hinge member (24) connectable to the bonnet (12), - a second hinge member (26) having a first end (30) and a second end (32), - a third hinge member (28) connectable to the body structure, and has a first state, wherein the first and second hinge members are releasably engaged to each other, and a second state being different from the first state. The hinge mechanism is displaceable from the first state to the second state by a pivotal displacement of the first hinge member with respect to the second hinge member. The hinge mechanism further comprises an abutment member (54, 54') attached to one of the first and second hinge members, such that when the hinge mechanism is in the second state, the other of the first and second hinge members abuts in a predetermined position relative to the abutment member, while the first and second hinge members are displaceable relative to each other via the abutment member.
