A screen door for a cooling package of a vehicle that includes proximal and distal frame posts, screen surface, torsion bar, stationary support, torsion bracket and fastener. The proximal frame post is hingedly coupled to the cooling package, and the distal frame post can be hingedly coupled to a secondary door. Proximal end of torsion bar is fixedly attached to proximal frame post, and distal end is moveable relative to the distal frame post. Stationary support is fixedly attached to distal frame post. Torsion bracket is fixedly attached to distal end of torsion bar, and is moveable relative to stationary support. Fastener maintains torsion bracket in a desired position relative to stationary support. Movement of torsion bracket relative to stationary support applies an adjustable torsion on torsion bar, and fastener maintains the adjustable torsion. An adjustment member can be attached to fastener between torsion bracket and stationary support.

Trunk lid stopper mechanism and method for controlling rotational speed of a trunk lid to slow down and halt its movement, and to hold the trunk lid at the halted position. The stopper mechanism comprises hinge arms for supporting the lid, torsion bars for applying biasing force to the lid, and link arms for transmitting biasing force from torsion bars to the hinge arms. Either each hinge arm or link arm is equipped with a stopper member that brakes the rotation movement of the trunk lid and halts the trunk lid fully-open. The stopper member has tapered surfaces for reducing relative rotational speed between the hinge and link arms by being forced therebetween during their relative rotational movement, and a stopper surface(s) for abutting against the other arm and halting the arms' relative rotational movement at the fully open position of the trunk lid.

There is provided a device to rotationally secure a member with respect to a base. The member is connected to an axle having an ellipse-shaped cross section through an elliptical or truncated-oval cavity for receiving the axle. As the member rotates, different tensions are experienced by the spring based on the orientation of the ellipse-shaped cross section with respect to the orientation of the cavity, thereby providing preferred orientations for the rotating member.

A hinge based counterbalance mechanism for operating a hinge of a closure panel of a vehicle to assist in opening and closing of the closure panel between a closed position and an open position about a pivot axis, the hinge drive mechanism including: a hinge having a body side portion for connecting to a body of the vehicle and a panel side portion for connecting to the closure panel, the body side portion and the panel side portion coupled via the pivot axis; a torsion element having a fixed end coupled to the body and a free end coupled to the body side portion, the fixed end inhibited from rotating relative to the free end and the free end able to rotate about a torsion axis of the torsion element; and a mechanical coupling mechanism coupling the free end to the panel side portion, the mechanical coupling mechanism providing for variability in torque output of the torsion element applied from the torsion element to the panel side portion as the hinge moves between the open position and the closed position.

A rotary damper has a housing, a damper shaft rotatably held on the housing, a damper volume accommodated in the housing and which has a magnetorheological fluid as working fluid, and at least one magnetic field source in order to influence a degree of damping of the rotational movement of the damper shaft relative to the housing. A separating unit connected to the damper shaft divides the damper volume. At least one gap portion, which can be influenced by a magnetic field of the magnetic field source, is formed between the separating unit, which is connected to the damper shaft, and the housing. The housing, the separating unit and the magnetic field source are designed such that a flow cross section for the magnetorheological fluid from one side to the other side of the separating unit changes in dependence on a rotational angle.

An urging structure for a lid includes a spring member having one spring end linked to a supply-port-forming member and the other spring end linked to a lid, and provided so as to be most elastically deformed at an intermediate position between a closed position and a maximum open position of the lid to urge the lid. The spring member is linked to the lid in such a way so as to vary a distance between the other spring end and a turning center of the lid, and the distance stays constant when the lid is in the closed position and in the intermediate position, increases in a process of moving from the intermediate position to the maximum open position, and becomes maximum when the lid is in the maximum open position.

A hinge system for a laptop computer is disclosed, the hinge system comprising first and second hinges that are tied together using a spring wire. The first and second hinges each have a display portion attached to a laptop computer display and a base portion attached to the laptop computer base. The spring wire is affixed to the display portion of the first hinge and the base portion of the second hinge, and is preloaded so that the laptop computer display opens automatically away at least partially away from the laptop computer base.
