摘要:
In a wind deflector for installation in a vehicle roof in a front area, comprising a wind deflector body which extends in a direction of extension transversely to a direction of travel, a lifting device, with which the wind deflector body can be moved between a position retracted into the vehicle roof and a position extended out of the vehicle roof and projecting beyond a contour of the upper side of the vehicle roof and thus deflecting wind, wherein the lifting device has at least one lifting unit with a mounting base and a lifting arm which is mounted with a lifting arm bearing for pivoting about a first pivot axis relative to the mounting base and engages on the wind deflector body at an end located opposite the lifting arm bearing, in order to achieve a reliable movability of the wind deflector body with devices which are as mechanically simple as possible it is suggested that an actuating unit which is supported on the mounting base and engages on the lifting arm be provided for moving the lifting arm and that the actuating unit and the lifting arm bearing be displaceable relative to one another in a direction of displacement extending transversely to the first pivot axis of the lifting arm bearing for the purpose of pivoting the lifting arm.
摘要:
A dynamic broadcast system as well as a terminal and a control device for use in such a dynamic broadcast system are presented. Transmission parameters, transmission times and transmission paths used for broadcasting and providing content, either via a broadcast network or a broadband network to terminals used in the dynamic broadcast system are dynamically controlled. Further, a decision logic is provided that dynamically decides transmission parameters, transmission times and transmission paths used for broadcasting and providing content based on monitoring data carrying information on user specific content usage and/or transmission quality data carrying information on the quality of a transmission link between a broadband server and a terminal and/or of a reception of content broadcast by a broadcast transmitter.
摘要:
The invention relates to a device and method for switching and/or controlling a number of functions by switching electrical supply lines and/or by means of remote control signals, wherein input commands are addressed and received using network addresses, the received input commands are converted into corresponding output commands for switching and/or controlling and the generated output commands are used for switching and/or controlling the functions.
摘要:
In order to design a protection device for motor vehicles, comprising a protection element protecting again draft and/or radiation, wherein for the mounting on a motor vehicle body the protection device has two fixing devices which are arranged on oppositely located sides and in which at least one locking element movable back and forth between an operative position and an inoperative position is mounted, so that it is easier to mount it is suggested that the fixing devices be coupled by means of a coupling device in such a manner that the at least one locking element of the one fixing device and the at least one locking element of the other, oppositely located fixing device can be transferred together from the operative into the inoperative position.
摘要:
A windbreak device for motor vehicles, in particular cabriolet vehicles, is provided, comprising a windbreak base which is disposed level with a beltline of a vehicle body, and a wind deflector which is connected to the windbreak base in an articulated manner and can be pivoted from an inactive position, which extends approximately level with the beltline of the vehicle body, into an active position which rises above the beltline and runs transverse with respect to said beltline, and an electric drive unit by which the wind deflector can be moved between the inactive and the active position relative to the windbreak base. The windbreak device is provided with a rechargeable battery which provides electrical energy for operating the electric drive unit.
