A headset has a headband and at least a first earphone. A coupler comprising a pivot having a torque resistance opposing the rotation of said pivot intercouples the headband and first earphone. The pivot includes a torque adjuster establishing said torque resistance.

An adjusting device serves for moving a moveable part into various positions, for example a side ventilator window of a motor vehicle. A servomotor (14) drives a spindle drive (18) which comprises essentially a spindle (24) having an external thread (26) and a sleeve part (28) which surrounds the spindle and has a corresponding internal thread (30). When acted upon by an external force, axial play in the region of the spindle drive (18) may lead to noise being produced; in order to avoid the noi...

An adjusting device (3) is suitable especially for use on a stand (1) for a surgical microscope (2). The adjusting device (3) makes it possible to move the surgical microscope (2) in a plane (9) perpendicular to the optical axis (8) of the surgical microscope (2). For this purpose, a transmission is provided in the adjusting device (3) which includes a coupling plate which is operatively connected to two force-transmitting elements. When this transmission is moved, at least one of the force-tran...

An adjusting unit for an article carrier is disclosed. The adjusting unit includes adjustable support elements for receiving articles of different sizes, in particular for supporting printed circuit boards of different sizes with a frame. One frame member of the frame may be used as a support for an article to be carried. At least one additional supporting element is provided which is adapted to be adjusted relative to a frame member. In addition, arresting structures are provided with the aid o...

An adjusting tool for use with an adjustable tangent assembly in a diaphragm gas meter includes a pair of coaxial tubes each having a face gear at one end, with operator manipulatable handles directly on the tubes so that an in-line configuration is attained.

An adjusting keyboard for a small, touch screen display for a personal digital assistant provides a system and method for selecting a character for entry when a key of the keyboard is struck off center. The system and method of the adjusting keyboard select the next character for entry from the keyboard based on the occurrence frequency of a predetermined number of previously entered characters and the distance the user has contacted the touch screen keyboard from the center points of proximate ...

An adjustable member such as a seat back of a vehicle is connected to an adjustment mechanism which transfers an external mechanical or manual force to the seat back. The adjustment mechanism includes an actuating element which rotates the seat back in either direction in response to the application of the external force. An elastic return element stores energy during such movement to subsequently return the actuating element to a rest position. During such return, the actuating element is autom...

A belt tension adjusting device provided on a scanner transmission belt to adjust the tension of the transmission belt, includes a helical spring that helps maintain the tension of the transmission belt, a retaining post for fixing the position of the helical spring, and a toothed recess for connecting the scanner to the transmission belt.

Infinitely operating two-way adjusting device having a rive element 1, an output element 2 adjustable in angle by operating the drive element 1, and a stepped switching mechanism mounted between the drive and output elements 1, 2 which contains a fixing device which when the adjusted position is reached by operating the drive element 1 blocks rotation of the output element 2 opposite the direction of rotation of the drive element 1. The infinite stepped switching mechanism has a coupling device ...

The invention relates to an adjusting device for an adjusting element which is arranged on a shaft, can be adjusted as desired in both directions of rotation by means of a drive and can be locked in any set position. The device has two jaws which can be moved together in a housing by means of the drive and, at least one end, are each in zero-play contact with an arm of a scissors-type arrangement, the opposing arms of the scissors-type arrangement being in zero-play contact with an output drive ...
