Abstract: Various embodiments include an actuator comprising: a drive element; a transmission section; an actuating element mechanically actively connected to the drive element through the transmission section; a reset spring exerting a closing force on the actuating element; and a coupling device providing a mechanically active connection between the reset spring and the transmission section. The coupling device is configured to be brought into a first coupling state and a second coupling state. With the coupling device in the first coupling state, the reset spring exerts the closing force on the actuating element in a first closing direction. With the coupling device in the second coupling state, the reset spring exerts the closing force on the actuating element in a second closing direction. The first closing direction and the second closing direction are different.

Abstract: An electronic assembly comprises a rotation device comprising a fixed platform defining a through hole. An annular groove is formed in the inside wall of the fixed platform. A first transmission element seats a plurality of teeth. A second transmission element is located in the through hole, and comprises a threaded axis portion and a toothed portion meshing with the plurality of teeth. A third transmission element comprises a rotation portion rotatably mounted in the interior of the annular groove of the fixed platform. A threaded hole is defined in the rotation portion, and is configured for cooperating with the threaded axis portion. A driver source is fixed on the fixed platform and is configured for rotating the first transmission element. An electronic device is mounted on the third transmission element.

Abstract: A rack-and-pinion type steering apparatus 1 includes a gear case 3 made of aluminum or an aluminum alloy and having a hollow portion 2; a steering shaft 6 rotatably supported by the gear case 3 through rolling bearings 4 and 5; a pinion 7 which is rotatably supported in the gear case 3 through the steering shaft 6; a rack bar 9 on which rack teeth 8 meshing with the pinion 7 are formed; and a rack guide 10 which is disposed in the hollow portion 2 inside the gear case 3 and supports the rack bar 9 slidably with respect to its moving direction A.

Abstract: A device for pressing a rack onto a pinion includes a pressure piece and a stop element. A spring element that applies at least one of two successive stages of contact pressure, which press the pressure piece against the rack, is arranged between the pressure piece and the stop element. The pressure piece and the stop element are each provided with mutually aligned contact surfaces which are located at a distance from each other in a basic position. At least one of the contact surfaces is configured in a springy manner such that the second stage of contact pressure begins as soon as the contact surfaces enter in contact with one another.

Abstract: An operating mechanism for a reciprocating component includes a moving member having a mounting section for attaching the reciprocating component, and a base with a guide. The guide has a backward path guide section and a forward path guide section that faces the backward path guide section. The moving member accumulates a backward travel force while being guided by the backward path guide section and moved to a mid point in the backward operation, and fully moves back by releasing the accumulated travel force from the mid point. The moving member accumulates a forward travel force while being guided by the forward path guide section and moved to a mid point from the fully moved back position in the forward operation, and fully moves forward by releasing the accumulated travel force from the mid point.

Abstract: An actuator assembly (10) including a motor (1) having a body portion (14) and a drive shaft (16), the drive shaft being drivably connected to a pinion (18), the pinion drivingly engaging an array of gear teeth (20) of a gear rack (22) the array of gear teeth having a first side (21) adjacent the motor, in which the gear rack is pivotally mounted via a pivot about a pivot axis (25A) on said first side (21) of the array of gear teeth (20).

Abstract: A rack and a pinion respectively have stoppers constituted by a flat surface in both sides of tooth portions thereof. The stopper of the pinion is brought into contact with the stopper of the rack at both oscillating stroke ends of the rack, whereby a backlash is absorbed.

Abstract: A window lift mechanism for raising and lowering a window in a vehicle door includes a support bracket mounted to the window and a motor supported on the support bracket. A vertical rack is mounted to the door and is positioned immediately adjacent the window, and a vertical guide track is also mounted to the door parallel to the rack and immediately adjacent the window. A pinion gear driven by the motor is supported on the support bracket and engaged with the rack to permit vertical movement of the window. A slide is supported on the support bracket and engaged with the guide track to provide support as the window is raised or lowered. Alternatively, a second rack and pinion are used instead of the guide track and slide. A manual drive mechanism for raising and lowering the window is also disclosed including a drive cable which transfers rotary torque from a drive pulley to a driven pulley supported on the support bracket.

Abstract: An actuating mechanism for a motor vehicle, wherein a first element can be fastened to a vehicle; and a second element, which is connected to the first element so as to swivel around at least one axis of rotation, exhibits a mounting for a manipulatable member. The second element is connected to at least one adjustable element, which can be actuated by a drive between the first and the second element, and to at least one friction element, which rests against the first element. The actuating mechanism may be used with a rearview mirror to provide an especially high controlling torque and a frictional force that is as constant as possible over its life time, whereby the number of parts is kept to a minimum and the assembly is especially simple. At least one friction element and one adjustable element form a one piece friction-adjustable element, which serves as the connecting element between the first and the second elements, and the friction-adjustable element is under a tensile load.
