Abstract:
An opening and closing mechanism for a lid (3) of a vehicle includes a body mounting member (21) adapted to be mounted on a body panel (36) of the vehicle alongside an opening to be selectively covered or exposed by the lid (3); a lid mounting member (24) adapted to be secured to the lid (3) to support the lid (3); first and second hinge links (22, 23) each pivotally connected at one end portion to the body mounting member (21) and at the other end portion to the lid mounting member (24) for establishing a compound pivotal movement to the lid (3) during opening and closing with the centre point of rotation at any stage of opening and closing being the point of intersection of the longitudinal centre lines of the first and second links (22,23); a motor (5) for providing a driving force to the first hinge link (22) for opening and closing the lid (3); and a drive transmitting member (25) for transmitting the opening or closing driving force from the motor (5) to the first hinge link (22). The drive transmitting member (25) has an abutment means (31) for directly engaging the lid mounting member (24) at an engagement point during the initial stages of closing the lid (3) from fully open. Alternatively or in addition it may have an abutment means (32) for directly engaging the lid mounting member at a different engagement point during the initial stages of opening the lid (3) from fully closed. The drive transmitting member (25) has a main drive connection (28, 30) for establishing a driving engagement between the drive transmitting member (25) and the first hinge link (22) during the intermediate stages of opening or closing the lid (3). The engagement points are selected such that torque transfer from the drive transmitting member (25) to the lid mounting member (24) has a greater mechanical advantage in the initial stages of closing the lid (3) from fully open or in the initial stages of opening the lid (3) from fully closed than during the intermediate stages of opening or closing the lid (3).
Abstract:
The invention relates to a force supporting device (10) for providing a load-dependent supporting force, particularly for a lowerable overhead luggage compartment (12) in an aircraft. The device (10) comprises a bracket (20) whose one end is attached to a supporting structure in a manner that enables it to pivot about an axis (P) and whose other end is designed for being connected to an object to which the supporting force should be applied. In addition, a gas-filled spring device (22) is provided whose one end is pivotally coupled to the bracket (20) and whose other end is pivotally coupled to one end of an oscillating lever (24) whose other end is pivotally attached to a bearing plate (18) and which can pivot relative to the bearing plate (18) between a first final position and a second final position. The oscillating lever (24) can be arrested at a number of positions in the area extending from its first final position to the second final position by means of an arresting device. A displacing device (46) serves to pivot the oscillating lever (24) according to a load determining device, which interacts with the adjusting device (46), between its first final position and its second final position.
Abstract:
The invention relates to a plastic door or side-panel module (1) for a vehicle door or a vehicle side-panel, said module being used to separate a wet side from a dry side. According to the invention, said door or side panel (1) forms a carrier for a window-lifter mechanism and a toothed gear part (2) that is associated with the window-lifter mechanism is formed as one piece onto the door or side-panel module (1). The invention also relates to a window-lifter mechanism, which comprises a door or side-panel module (1) of this type, to a vehicle door comprising a corresponding door module (1) or a corresponding window-lifter mechanism and to a method for producing a door or side-panel module (1) of this type.

Abstract:
The invention relates to an electromechanical hinged wing drive comprising a door closer (1) with an eccentric pinion (6) that has a circular pitch circle and that intermeshes with a toothed rack (5) that is mounted on the piston (4). The invention is further characterized in that the pitch circle and the teeth (9) of the toothed rack (5) are adapted to the teeth of the pinion (6). In order to obtain an optimum displacement of the piston (4) in the housing (2) of the door closer (1) the design of the closing delay is improved.
Abstract:
A liftgate force control assembly (20) adjusts the force required to move a liftgate (12) that is pivotally secured to a motor vehicle (10) using a hinge (14). The liftgate force control assembly includes a track (42) that is fixedly secured to the motor vehicle. A follower (46) is movably secured to the track. A strut (34, 36) has a movable end (26, 28) and a secured end (30, 32). The secured end (30, 32) is pivotally secured to the liftgate (12) and the movable end (26, 28) is pivotally secured to the follower (46). The strut (34, 36) defines a moment with respect to the hinge that secures the liftgate to the motor vehicle. A motor (50) is connected to the follower (46) to move the follower (46) along the track (42) changing the moment of the strut such that the force required to move the liftgate (12) changes as the moment changes.
Abstract:
An einem Scharnierbügel (1) für eine schwenkbare Kraftfahrzeug-Heckklappe greift in einem einen Hebelarm definierenden Abstand von seinem ortsfesten Schwenklager (2) eine Gasfeder (6) zur Unterstützung von Schwenkbewegungen der Klappe an. Zur Kompensation des Temperaturgangs der von der Gasfeder (6) ausgeübten Kräfte ist ein temperaturabhängig angesteuerter Servo (10) vorgesehen, der bei Temperaturänderungen durch Verlagerung der Angriffsstelle der Gasfeder (6) den Temperaturgang der von ihr ausgeübten Kräfte kompensiert.
Abstract:
Es ist die Aufgabe der Erfindung, einen Torantrieb zu schaffen, bei dem die elektrische Antriebseinheit einfach und kostengünstig herzustellen ist, einen Elektromotor relativ geringer Leistung benötigt, geringen Raumbedarf erfordert und dennoch selbsthemmend ist. Dieser Torantrieb kennzeichnet sich dadurch, daß das Getriebe ein Differenzgetriebe umfaßt, bei welchem sich eine Abwälzhülse (1) mit ihrem Umfang (3) mit mindestens einem Umfangsabschnitt am Gegenumfang (4) einer konzentrisch angeordneten Stützhülse (2) abwälzt, Umfang (3) und Gegenumfang (4) unterschiedlich lang sind, der Umfang (3) der Abwälzhülse (1) eine unrunde, insbesondere elliptische, Form einnehmen kann und in radialer Richtung so flexibel ist, daß die Winkellage der unrunden Kontur gleichmäßig mit Hilfe eines Antriebes (11) um die Achsrichtung (5) herumwandern kann, ohne das flexible Bauteil (1) bzw. (2) selbst rotieren zu lassen, und das unrunde Teil (1) oder (2) mit einer Abtriebsachse (8) in Wirkverbindung steht.
