The invention relates to a windshield wiper device, particularly for a motor vehicle, comprising at least one wiper shaft (10). Prior art windshield wiper devices having predetermined breaking points exist in order to meet the high demands of pedestrian impact protection. However, the risk of these predetermined breaking points rupturing during the operation of the wiper exists in this type of windshield wiper device. In addition it cannot be guaranteed that the predetermined breaking point ruptures in the event of a pedestrian impact. Therefore, in the inventive windshield wiper device, the at least one wiper shaft (10) can be displaced under the action of a force.

The invention relates to a driving mechanism (11) for the traction-exerting component (13) of a conveyor device (1), with a frame (10); at least one reversing wheel (15a, 15b) and one driving wheel (17) supported on said frame; an endlessly revolving, flexible traction-exerting component (13) guided around the reversing and driving wheels (15a, 15b; 17) and having a pulled strand and a returning strand; a tensioning device (18); as well as a setting device comprising the tensioning device. The tensioning device (18) has two support bodies arranged one behind the other in the direction of revolution of the traction-exerting component (13), said support bodies being adjustable against one another, and tensioning elements each supported on said support bodies. With its pulled strand, the traction-exerting component (13) is guided around one of the tensioning elements, and with its returning strand around the other tensioning element, as well as around the reversing and driving wheels (15a, 15b; 17), whereby tensioning forces directed against each other are admitted to the tensioning elements, which are arranged spaced from each other; and whereby the spacing is adjustable to a limited extent via the at least one setting element.

A compact, energy-efficient extensible illumination source combines the reliability advantages of light emitting diodes (LEDs) with the brightness of conventional lighting. High reliability of the LEDs provides trouble-free operation over a long hour lifetime. This high-output light source can be used in direct lighting applications or for backlighting for translucent materials. The illumination source includes LED printed wire board segments that may be configured to form a light line of any length. The segments are mounted on a inner mounting base which also serves as a first stage heat sink for the LEDs. The illumination source includes a linear mirror for reflecting radiant energy away from the LEDs to produce a uniform linear illumination pattern. A window provides mechanical protection for the LEDs and may be used for diffusing or filtering light from the LEDs. An integral base in contact with the inner mounting base also serves as a heat sink and provides structural support for the illumination source. The integral base further includes channels and cavities for cooling the illumination source and for housing power cables.

A positioning device for a hand-held setting tool (10) having an actuation switch (13) for actuating the setting tool (10), with the positioning device including a rod-shaped holder (21); a connection element (22) for the setting tool (10) arranged at an end of the holder (21), and an actuating switching device including an actuation element (24), a switching link (30) connecting an actuation element (24) to the actuation switch (13), and a safety device (40) for preventing actuation of the actuation switch (13) and having a gravity-controlled intermediate element (41) having an actuation position in which it is positioned between first controlling element (34) and second control element (35) of the switching link (30), and an interruption position (16) in which it interrupts the switching link (30).
