A guiding rail for guiding a door leaf between an opening position and a closing position in relation to a door opening in a wall includes: at least one guiding section with a guiding compartment, in which a sliding element is accommodated to be movable, wherein the guiding section includes a guiding opening, through which a bearing axis of the sliding element exits at least partially from the guiding compartment, at which axis a lever element is supportable to be rotationally movable, in order to establish an operative connection between the sliding element and the door leaf. The guiding rail further includes at least one functional section with a functional compartment, in which a transmission means is receivable, which serves for transferring electrical energy and/or data between at least a wall-sided energy source and a door leaf-sided energy recipient and a labyrinth guide between the guiding and functional compartments.

A window system includes a window frame; a transparent window pane; an energy harvesting device coupled to the window frame or the transparent window frame; an output device that uses or transmits electricity; and a battery housed in the window frame, the battery being in electrical communication with the energy harvesting device and the output device.

A sliding door assembly comprises a sliding door leaf, a sliding door rail, and a door operating assembly for operating the door leaf. The door operating assembly has a drive unit to drive the door leaf along the sliding door rail. The sliding door leaf has at least one wagon member attached thereto. The wagon member is connected with the drive unit. An electric component is mounted to the sliding door leaf. A cable arrangement transfers power and/or communication signals between the door operating assembly and the electric component. The cable arrangement comprises a flexible portion with an end section that is fixed in relation to the sliding door leaf to allow the flexible portion to extend to compensate for the movement of the sliding door leaf.

Provided is an electric power supply device in which exposure of a wire harness can be reduced in a slide door and interference with door trim can be minimized. When a slide door is half opened, a wire harness bends convexly downward, and one portion thereof is positioned lower than when the slide door is fully open or fully closed. Specifically, the wire harness is bent three-dimensionally. This makes it easier for the wire harness to be pulled out from a bottom end of door trim, and makes it possible for interference between the wire harness and the door trim to be minimized. The wire harness may be also bent three-dimensionally as appropriate in accordance with a shape of the door trim, reducing exposure of the wire harness in the slide door.

A device for fastening and electrical contacting of a vehicle window pane with an integrated electrical functional element is presented. The device includes a pane adapter that is fixed on the window pane; a pane holder that couples the pane adapter with a vehicle body; a pane-side plug that establishes electrical contact with the functional element when the window pane is assembled; and a pane-side coupling shoe for mounting the pane-side plug on the window pane. The device further includes a mating plug that couples with the pane-side plug to provide electrical contact of the functional element to a control unit. The pane adapter, the pane-side coupling shoe, the pane holder, and a plug holder that supports the mating plug, are kinematically coupled so that during assembly of the window pane using the pane adapter on the pane holder, the pane-side plug is connected to the mating plug.

A garage door opener system having a garage door opener and a remote input device electrically connected to the garage door opener by an electrical conductor. The remote input device receives power by the electrical conductor. The remote input device includes a device controller to communicate an event message, monitor for an acknowledgement message within a time period, and repeat the event message when the acknowledgement message is not received within a time period. The garage door opener includes a master controller. The master controller receives the event message and communicates the acknowledgement message in response to receiving the event message. Also disclosed is a method of operating the garage door opener system.

In a wire harness routing structure, a main link arm supports a door main body to be slidable with respect to a vehicle body while relatively rotating with respect to each of the vehicle body and the door main body. A sub-link arm supports the door main body to be slidable with respect to the vehicle body together with the main link arm while relatively rotating with respect to each of the vehicle body and the door main body. A first wiring line is provided to be routed along the main link arm, and connects a vehicle body-side connector on the vehicle body side and a door-side connector on the door main body side. A second wiring line is provided to be routed along the sub-link arm and connects the vehicle body-side connector on the vehicle body side and a second door-side connection target on the door main body side.

A door system comprises a door frame adapted to be mounted within an opening, a door pivotally attached to the door frame, a power converter such as an AC/DC converter operably associated the door frame, and a DC electric device mounted to the door and electrically connected to the AC/DC converter. The AC/DC converter is configured to be electrically connected to an AC power unit operably associated with the door system.
