Patent ID: 7043797

Claim:
A vehicle compartment hinge retarding device insertable between two rotationally connected members connected to rotate relatively only about a single hinge axis; the rotationally connected members forming a vehicle compartment hinge; said device being configured to oppose and retard such rotation in a predetermined manner and comprising: a substantially cylindrical support carried integrally by one of the rotationally connected members and being substantially coaxial with the hinge axis; a coil spring interference fitted to the support and terminating with two opposite radial arms protecting towards the other of the rotationally connected members; and a retaining seat carried integrally by said other member and on which seat the arms of the spring rest, on opposite sides thereof, and are stressed by said other member; wherein said spring is configured to deform upon relative rotation of said members about said hinge axis so as to progressively reduce and, beyond a certain point of the moving path of said other member, completely eliminate the interference with which said spring is fitted to the support; and the two rotationally connected said members are connected to each other by a pin defining said hinge axis and inserted coaxially through said substantially cylindrical support.
