Abstract:
An actuating mechanism for a pivotably mounted actuating arm, in particular for driving a flap of an item of furniture, wherein the actuating arm is acted upon by a spring device, and wherein an electric drive acts on the actuating arm via a transmission mechanism, and wherein the transmission ratio of angle of rotation (α) of the motor to angle of rotation of the actuating arm is varied over the angle of rotation range of the actuating arm by the transmission mechanism.
Abstract:
The invention relates to a hinge arrangement, in particular for a tailgate of a motor vehicle, having a first hinge part, in particular firmly connected to the body, which is knuckle-jointed with a second hinge part, and having an energy accumulator, the force application points of which are positioned in relation to both hinge parts in such a way that the force released upon its discharge supports the rotation of the two hinge parts around the hinge axis from a first rotation position, which corresponds in particular to a closed position of the tailgate, to a second rotation position, which corresponds in particular to the open position of the tailgate. To obtain useful improvements, a transposition device is proposed for transposing at least one force application point in one of the two rotation positions, so that after a transposition onto the hinge parts a force acts in the opposite rotation direction.
Abstract:
The invention relates to a drive unit for automatically actuating a tailgate of a motor vehicle. Connecting the drive unit (4) to the vehicle door (1) or to a transmission device (6) by means of an output shaft (5), said transmission device executing a pivoting movement which corresponds to the pivoting movement of the vehicle door (1), and the drive unit (4) comprising at least one first sensor device (7), which can be connected to an electronic evaluation device (21) and serves to detect the respective angular position of the vehicle door (1). In order to make use of the advantages of an incrementally operating position measurement system of the vehicle door (1), in which, recalibration is necessary not only after the end positions of the vehicle door (1) are reached following a power cut. The invention proposes dividing the entire pivot angle (à) of the vehicle door (1) into at least three successive zones (pivot angle ranges) (à1-à4), it being possible to determine the individual pivot angle ranges (à1-à4) by means of a first sensor device (7), which is suitable for detecting absolute values. The pivot angle of the vehicle door within the individual zones (à1-à4) is then detected with the aid of a second sensor device (8), which comprises at least one incrementally operating measured value detector.

Abstract:
A method and system for controlling the descent of a moveable element pivotally attached to a rigid structure. The moveable element is pivotally attached to the rigid structure, and is then pivotally connected to a compressible strut, which is attached to a linkage pivotally connected to the rigid structure. The descent of the moveable element is pivotally controlled using a microcontroller and a motor attached to the linkage, and the control path for the linkage is selected based on a comparison of the angle between the linkage and the rigid structure and the angle between the moveable element and the rigid structure.

An upwardly acting sectional door system including, a door (D) having a plurality of hinged door sections (16-18) movable between a closed vertical position and an open horizontal position, a drive tube (31) mounted above the door in the closed vertical position, an operator (11) selectively directionally rotatably driving the drive tube, cable drums (35) mounted on the drive tube for rotation therewith by the operator, springs (60) mounted in operative relation to the cable drums, and counterbalance cables (75) reeved about the cable drums and interconnecting the springs and the door to counterbalance the door when moving between the closed vertical position and the open horizontal position.
Abstract:
A power-operated system for actuating the rear doors or liftgates of motor vehicles is disclosed. The system includes a strut assembly having two struts, each strut mounted on one side of the door between the door and the vehicle's door frame. One end of each strut is connected to a powered rotating arm. To open the door, the rotating arms change the angular orientation of the struts such that they have a substantial mechanical advantage. In this position, the force provided by the struts overcomes the weight bias of the door, thus opening the door. To close the door, the rotating arms change the angular orientation of the struts such that the struts have a decreased mechanical advantage, reducing the force provided by the struts, and therefore causing the door to fall closed under its own weight bias. A control system for controlling the power-operated system is also disclosed.

Abstract:
A four bar link is provided between a walled cargo area of a truck and a rigid rear cargo door. The effective length of the lower link of the four bar linkage is longer than that of the upper link such that the motion of the door is generally up and over the top of the truck body. An eccentric cam is joined to the upper link with a tensioned spring extending around the cam such that the spring slackens as the door opens. The cam is configured so that, as the door is opened, the spring slackens more slowly initially then more quickly. This allows the door to be moved initially mostly outwardly before moving significantly upwardly and still be effectively counterbalanced throughout its motion.
Abstract:
A driving motor (1) for an actuating drive having improved jamming protection of a closing part, e.g., a window pane (2) of a motor vehicle. The closing part is adjusted via a transmission, e.g., a cable drive drum (3, 4). To avoid over-dimensioning of the driving motor (1), a variable transmission is provided that delivers a substantially constant load on the driving motor (1) over the entire adjustment path of the window pane (2). Thereby, a design of the driving motor (1) to cope with an increased load, which would otherwise be caused when the closing part slides into a closed position, is avoided. In addition, since the closing part approaches the closed position with a lower speed, the closing part is able to brake rapidly, if necessary. This results, e.g., in an improved jamming protection function of the closing part.
