  • Patent number: 7073851
    Abstract: A guide rail (10) for the roof opening system of a motor vehicle has several lengthwise guide rail segments (12, 14) which are located in succession in the guidance direction (a), and at least one adapter (16) located in a transition area between adjacent guide rail segments (12, 14). The adapter provides for a continuous guide transition (22) between the coaxial guideways (18, 20) of the adjacent guide rail segments (12, 14). In such a guide rail, viewed over the length of the guide rail, guideways and cable channels can also be arranged nonuniformly and the guide rail segments can be made completely individually, especially optimized for the respective area of the task.

  • Publication number: 20050128483
    Abstract: A method for beam guiding of a light beam generated by a light source to a target location along a path distance LS, comprises splitting the light beam on the path distance LS at least once into a first partial beam and a second partial beam, guiding the first partial beam additionally at least once along a delay line, the first partial beam thereby covering an additional path distance LD, guiding the second partial beam only along the path distance LS, combining the first and second partial beams after the first partial beam having passed through the delay line and guiding the combined beam to the target location, wherein the light beam is guided along the path distance LS and LD in such a way that the light beam generated by the light source has a predetermined beam width B at the target location, expanding the light beam between the light source and the target location at least once to a beam width B?>B and comprising the light beam again at least once in such a way that the light beam has the predeterm

  • Patent number: 6877799
    Abstract: An openable motor vehicle roof, which is provided with at least one cover (10, 110) which, in the closed position, closes at least part of a roof opening (46), with a carriage (36, 136) which can be moved in the lengthwise direction of the roof in a first roof-mounted guide (38) by a drive, and with a cover-mounted cover carrier (12, 112) which is movably guided in the lengthwise direction of the roof by a first sliding element (16, 116) in a second roof-mounted guide (20) and by a second sliding element (18, 118) which is offset to the rear relative to the first sliding element in the third roof-mounted guide (22). The cover can be raised at its rear edge by displacement of the carriage to the rear and can be pushed to the rear with the rear edge of the cover raised to clear the roof opening.

  • Publication number: 20030223132
    Abstract: The invention relates to a method for variably attenuating the intensity of the light beam, in the case of which method the light beam is directed onto at least one optical arrangement, that has at least one body transparent to the light beam, in such a way that the light beam enters the at least one body through a light incidence surface and emerges again from the at least one body through a light emergent surface, the at least one body being moved in position relative to the incident light beam, in order to change the intensity of the emergent light beam with reference to the intensity of the incident light beam.

  • Patent number: 6604782
    Abstract: A openable motor vehicle roof with at least one cover (10, 12) which can be moved out of a closed position in which it closes a roof opening along a roof guideway (14) to the rear into a deposited position in a rear gate (16) of the motor vehicle. The rear gate is provided with a guideway (22) for the at least one cover and is coupled to the vehicle body to swing about a transverse pivot axis that is located on or near its upper end in order to be swung out of the closed position into an open position. The guideways (14, 22) and the rear gate (16) are made such that the transfer of the at least one cover to the rear gate takes place in a transfer position of the rear gate which lies between the closed position and the open position of the rear gate (16).

  • Patent number: 6572183
    Abstract: An openable motor vehicle roof is provided which includes a cover which in the closed position closes at least part of the roof opening, a cover-mounted cover carrier which is provided with a first crank path, and a slide which can be moved in the lengthwise direction of the roof by means of a drive in a first roof-mounted guide channel. The front area of the cover is movably guided in a second roof-mounted guide channel. A first engagement element, positioned on the raising lever, engages the first crank path and a second engagement element, attached to the raising lever, is movably guided in a third roof-mounted guide channel to control a raising motion of a raising lever. The rear edge of the cover can be raised out of the closed position by moving the slide by means of the raising lever. The first crank path is shaped such that when the raising lever is not raised, the displacement of the first engagement element in the first crank path causes a raising motion of the cover.

  • Patent number: 6550851
    Abstract: A motor vehicle roof with a roof module (10) for attachment to the roof frame area of a motor vehicle body, with support edges (15) for the roof module (10) which inwardly adjoin the side rails (14) of the vehicle body, the roof module (10) having an outside roof skin (11) which has side edges (16) which are bent downward toward the support edges (15). On the roof skin (11), in the area of its side edges (16), there are connecting strips (18) which have bottoms for attachment to the support edges (15) of the roof frame area and which are joined to the roof skin (11), preferably by being injection molded or foamed on to it.
