  • Patent number: 8287028
    Abstract: A roof structure for a cabriolet vehicle has a top (10) with a top material and a substantially U-shaped corner bow (19) that extends transversely with respect to the longitudinal direction at a position substantially adjacent to a rear window. The corner bow (19) has lateral limbs (20) with free lower ends (21). Molded elements (23) are plugged onto the free lower ends (21) of the lateral limbs (20) of the corner bow (19) and can be plugged into recesses near the B pillars of a body structure of the cabriolet vehicle. The molded elements (23) are configured to guide the top material of the top (10) in sections in a closed state of the top (10). Sealing elements (27) are mounted on the molded elements (23) and interact with vertically running edges of side window panes.

  • Patent number: 7416240
    Abstract: The invention relates to a cabriolet vehicle (1) with a roof (2; 102), comprising at least two moving units (6, 14; 106, 114) each mounted on main bearings (7, 8; 15, 16; 107, 108; 115) fixed to the chassis such as to move and each of which is provided with a rigid roof section (3, 4; 103, 104). At least one rear rigid roof section (4; 104), comprising a rear window (5; 105), is connected to a main bearing (15, 16; 115) by means of a multi-part articulated chain (17; 117), whereby a part (18; 118) of the articulated chain (17; 117) brings about at least one movement of the rigid roof section (4; 104) relative to the main bearing (15, 16; 115) and a part (19; 119) of the articulated chain (17; 117) brings about at least one change in the angular position of the rigid roof section (4; 104).

  • Patent number: 6832804
    Abstract: A convertible vehicle has a carbody having a rear area and a roof stowable in the rear area of the carbody. The roof has a rigid rear roof end member and a rear window. A passageway allows movement of the roof relative to the carbody. The passageway, when the roof is in a closed position, is located in front of the rear roof end member and below the rear window. A movable cover functioning as a rear deck closes the passageway at least partially. The movable cover is connected to the roof in an area of the rear roof end member and is movable together with the roof.

  • Patent number: 6702362
    Abstract: A convertible vehicle has a carbody having a rear area and a roof connected to the carbody. The roof has a first rigid roof part arranged rearwardly and provided with a rear window. The roof further has at least one second rigid roof part. The first and second roof parts can be nested into one another when opening the roof and stowed in the stowed position in the rear area of the carbody. The first roof part is positioned in a stowed position of the roof above the at least one second roof part in a substantially horizontal position. The rear window has an exterior side in a closed position of the roof, and the exterior side of the rear window in the stowed position faces upwardly.

  • Patent number: 5628203
    Abstract: The invention is directed to a system and process operating on an air-standard cycle either to cool or heat a room. The system may be advantageously employed to cool or heat relatively small areas or rooms, particularly driver's cabins in locomotives and the like. In cooling operation, outside air is expanded in a turbine, cooled below ambient, and introducted into a heat exchanger. Air from the room to be cooled is introduced into the heat exchanger and heat is removed therefrom. Suitable valves are provided to change the operation of the heat exchanger to that of a regenerator and to direct the flow of air accordingly. Specifically, air heated by compression in the compressor is directly introduced into the room and air leaving the room is passed through the regenerator/heat exchanger and released into the atmosphere.

  • Patent number: 4987346
    Abstract: The invention relates to a particle source with which positive, negative, and neutral particles can be generated and applied on a substrate. The particle source comprises a container (26) in which a gas or gas mixture to be ionized is held. Into this container (26) an electromagnetic wave irradiates which preferably is a microwave. A torus-shaped magnetic field, which is generated with the aid of permanent magnets (32, 33) or electromagnets, simultaneously projects into the container (26). With the aid of a special control grid configuration (38, 39, 40) it becomes possible to draw off positive, negative or neutral particles from the container (26).
