A belt tensioning device for traction mechanisms includes a receiving and mounting housing, a pulley carrier pivotally connected to the receiving and mounting housing, a bearing supporting the pulley carrier relative to the receiving and mounting housing, and a spring located between the pulley carrier and the receiving and mounting housing for applying the tensioning force. The belt tensioning device, in normal operation, on the slack side between a generator and a main pulley can also be used when the slack side becomes the load side by a blocking mechanism which enables swinging motion of the pulley carrier relative to the receiving and mounting housing in a first direction, and limits or prevents such motion in a second, opposite direction.

An operator control device for functional adjustment of a functional device includes an operator control knob which has an off position in which the operator control device is deactivated. Said knob can be brought into a working position for functional adjustment purposes. The working position is predetermined by a lock-in position, and, starting from the working position, the operator control knob can be pulled out of the operator control device or pressed into the operator control device against a counterforce which increases as the distance from the working position increases. Here, the operator control device includes a movement detection means for detecting movement of the operator control knob out of the working position in one direction or in the other direction. The movement detection means is connected to a controller of the operator control device so as to carry out functional adjustment in a manner dependent on the detected movement.

A code switch for an electrical appliance comprises triggering magnets at specific points in a rotatable rotor. Stationary opposite contacts are disposed in the housing of the code switch and wipers are provided with contact heads assigned to said opposite contacts at a disconnecting distance. When a triggering magnet is moved above an opposite contact by rotating the rotor, the contact head is pulled upward by magnetic force towards the opposite contact and the contact is closed.

In a hob (11), an operating toggle placed on a front panel (17) has on a connected power control device an actuator (23) for producing a haptic acknowledgement or response in the case of operation. The operating toggle (19) also has a proximity sensor (27). If a hand (29) approaches the operating toggle (19) for operation, this is detected by the proximity sensor and it brings the actuator (23) from a current-economizing standby mode into a normal mode, where it operates normally. If the hand (29) is removed again, it is again brought into the standby mode.

A device for locking and quickly unlocking of relatively movable parts has an actuator having an electromagnet with a movable core and a latch coupled or operatively connected on the one side to the actuator or the movable core and on the other side to the movable part, the latch having pawls pivotal on fixed axles. A fixedly mounted housing has a seat fitted to the actuator or the electromagnet such that the actuator or the electromagnet is held immobile and unmovably in the seat. The axles for the pawls of the latch are formed in the housing, and the housing has a cutout for engagement of one of the movable parts part and one of the pawls. A plug on the housing fits with external connecting means, and connecting parts on the housing connect the actuator to the plug on the housing.

A control device for converting a control movement along a control path into a control signal has the control path corresponding to different control stages or control types. The control device has two measuring tracks with a linearly changing resistance associated with each track. In one embodiment, these measuring tracks are positioned concentric to each other in a semicircle. A voltage U, which is tapped via two opposite interconnected sliders, is applied to both measuring tracks at a junction point while the other junction point is connected to ground. If the detected values of the tapped voltages deviate from a corresponding stored value or pairs of values, there must be a fault, due to, for example a broken slider. This makes it possible to perform a test for determining the fault or a malfunctioning control device.

A part normally retained in a predetermined position is operated by a pyrotechnic actuator having a housing formed unitarily with a pivot, formed unitarily with mounts for securing the housing to a motor vehicle, and forming a chamber extending along an axis. A latch element is mounted on the pivot and movable thereon between a holding position retaining the part in the predetermined position and a releasing position allowing the part to move out of the predetermined position. A piston having a stem engageable with the latch element is movable axially in the chamber between an inner position with the latch element in the holding position and an outer position with the latch element in the releasing position. A pyrotechnic charge in the chamber is detonatable to shift the piston into the outer position and thereby shift the latch element into the releasing position.
摘要:
A rotary selector may include a first switch contact, which is open in an off-mode angular range, and which is closed outside of said off-mode angular range, in particular used for switching on or off an electrical load. An encoding device may generate an angle-dependent code over a predefined angular range. The rotary selector may also include a second switch contact, which is closed in a plurality of start-angular ranges, and which is open outside of said start-angular ranges.
