Also provided is a plurality of connecting elements () for connecting the upper part () and the lower part (), the connecting elements () being spaced apart along a longitudinal extent () of the wiper blade () and being attached to the upper part () and/or the lower part () by a rotary joint, and the connecting elements () being designed to allow a motion of the upper part () and the lower part relative to each other with a motion component along the longitudinal extent () of the wiper blade (). The window-wiping device also has a wiper-blade-side fastening part (), which is accommodated in the wiper blade head (), and a fastening element (), which can be attached to the drive shaft () and into which the wiper-blade-side fastening part () can be locked and which has an actuating device (), which is designed to release the wiper-blade-side fastening part () from the fastening element () as a result of an actuation, wherein the actuating device () has a blocking element (), which is designed to block actuation of the actuating device ().

Fin ray wiper

The invention relates to a wiper device comprising at least one wiper strip unit (-) which has at least one first wiper lip (-) and at least one second wiper lip (-). The wiper device (-) has at least one automatically activated wiper lip switching unit (-) which is provided in order to switch a wiper lip (-) that is active in at least one sub-process of a wiping process.

Wiper device

The invention relates to a method for controlling a wiper device () by means of a control and/or regulating unit (). At least one operating parameter is set dependent on at least one parameter which differs from a vehicle window coverage parameter.

Wiper device and method for controlling same

The invention is based on a wiper arm arrangement comprising at least one wiper fluid channeling unit () that has at least one wiper fluid duct () and at least one coupling unit () which is designed to be connected to a wiper stem () of a wiper arm (). () cha It is proposed that the at least one wiper fluid duct () be made integral with the at least one coupling unit ().

Wiper arm arrangement

The invention proposes a wind deflector unit, more particularly a wiper arm wind deflector unit, having at least one wind deflector element (), having at least one first coupling unit () which in an installed condition is designed to be connected to a wiper stem () of a wiper arm (), and having at least one second coupling unit () which in an installed condition is designed to receive a wiper fluid duct ().

Wiper arm wind deflector unit

With the disclosure shaft drive device, has a PCB device ( &prime;); a rotor device ( ) with a rotor ( ) and a rotor shaft ( ) attached to it; and a stator device ( ) for driving the rotor ( ) with the rotor shaft ( ); an attachment device ( ) for attaching the rotor device ( ) and the stator device ( ) to the PCB device ( &prime;) in such a way that the PCB device ( ) forms part of the frame, surrounding the rotor shaft, of the shaft drive device.

Shaft drive device

In an ultrasonic sensor, including a housing having a plug connector, an ultrasonic converter, and a circuit board, the housing is divided into a support and a hood enclosing the support. The support carries the circuit board, the plug connector, and the ultrasonic converter.

Ultrasound sensor

An ultrasonic transducer having a pot-like casing has an outer bottom face which is designed in part as a vibrating diaphragm. A stabilizing ring is arranged on the outside of the wall of the pot-like casing, imparting a greater rigidity to the casing and limiting the ultrasonic vibration essentially to the bottom of the pot as a vibrating diaphragm. The propagation and reception beams of the ultrasonic waves can be shaped further by an additional arrangement of a sound directing device in the area of the vibrating diaphragm.

Ultrasonic transducer

An ultrasonic transducer has a pot-like housing with an annular wall and with a bottom surface serving as diaphragm. A piezo-element which is connected with connection lines is arranged at the inner side of the bottom surface. The edge remote of the bottom surface is surrounded by a decoupling ring which is formed as a holder for the connection lines.

An arrangement having a module for installation in a bumper of a motor vehicle and having a retaining part for attaching the module to the bumper. The retaining part, in this context, is fixedly attached on the interior side of the bumper blade, so that the module can be inserted from the interior side. Provision is made in the bumper for a corresponding bore, through which the head piece of the module can be plugged in until the surface is roughly flush with the exterior surface of the bumper. As the module, an ultrasonic sensor is preferably proposed, which can be used for measuring distance in a motor vehicle. Since only the head piece of the module is visible from the outside but not its attachment parts, the resulting appearance is particularly advantageous since it is not disruptive from a design point of view.

Modular device to be inserted into a vehicle bumper

In a control device the printed circuit board (,) rests on a rim (,) of the housing bottom (,). The power components (,) to be cooled are arranged in the area where the printed circuit board (,) rests on the rim (,). In order to achieve an even contact pressure of the printed circuit board (,) over the entire support surface, a contact pressure on the power component (,) or on the printed circuit board (,) is generated with the help of additional aids. It is possible here to use spring elements (,) or elastomer strips (,) acting on the power component (,). Furthermore, multi-part support elements (,), or respectively plastic elements (,) can also be employed, which respectively act directly on the printed circuit board (,). A good heat dissipation from the power component (,) via the rim (,) of the housing bottom is possible by means of this.

Control device consisting of at least two housing sections

In order to improve an arrangement for mounting a wiring harness on a support plate with a laminated-on substrate for electrical and/or electronic components such that the latter has high reliability while being simpler and thus more economical to manufacture, the connecting wires of the wiring harness are connected in electrically conductive fashion directly to electrical connection elements of the substrate. In the vicinity of this connection, the wiring harness is at least partly embedded into a sealing medium enclosing the connection.

Apparatus for an internal combustion engine

The housing (10) of an electrical device, in particular a switching and control device for motor vehicles, includes an upper shell (11) and a lower shell (12), and PC boards (15, 25) are located in both shells (11, 12). The required power components (17) are distributed to both PC boards (15, 25). The lower shell (11) of the housing (10) has side walls (16) encompassing three sides. The upper shell (11) has, in addition to the outer rim (21) extending around three sides, a protrusion (22) protruding into the housing on two opposed sides, so that a space (23) is created between the rim (21) and the extension (22). In the assembled state, the side wall (16) protrudes into the space (23) in the other shell (12). The power components (17) rest on the inner wall of the side wall (16) or of the extensions (22), so that the lost heat can be dissipated in a simple way.

Multi-board electrical control device

Securing mechanisms are employed in known plug connections, which have components designed in a complicated way, the manufacture and assembly of which entails high cost and which result in bulky plug connectors. The plug connection in accordance with the invention is designed in such a way that a securing ring (18) formed in one piece on a second part (11) has stop shoulders (29) which, for securing the plug connection, grip, stationary detents (46) of a first part (41). The securing ring (18) has the shape of a convexly closed polygon (24), the corner points (26) of which have a reduced wall thickness in comparison with the polygon lines (27). The polygon lines (27) can be kinked at the corner points (26) by means of squeezing pressure forces acting on the securing ring (18), which allows the disconnection of the securing of the plug connection. This results in a plug connection of low mass which can be manufactured in a cost-effective manner. This plug connection is preferably employed in motor vehicles which are subject to oscillation increases during operation.
