  • Patent number: 4969681
    Abstract: A frame arrangement for a vehicle roof that has a roof opening that is closable by a displaceable cover panel that, along with driving and guiding components thereof, is supported on a frame bounding the roof opening which has only the function of a support, i.e., does not form a necessary part of a fully functional installation unit, comprising a guide insert and a covering. The guide insert and the covering form the tracks for a slidable guide element and the cable guide channels for actuating cables, which interact with an appropriately suitable actuation device for displacing the cover panel. The guide insert can be made of plastic or metal, and the covering is advantageously divided into a front side section and side sections. These sections of the covering can be uniformly produced of plastic or metal or individual sections can be produced of plastic and others, in turn, of metal. Also, the guide insert as well as the covering can be produced entirely of plastic.

  • Patent number: 4968090
    Abstract: A frame arrangement for a vehicle roof of the type having a roof opening which can be closed and selectively at least partially opened by displacement of a cover panel by actuating cables, the cover being guided by guide element tracks on the side parts of a support frame. According to the invention, the frame arrangement is provided with a guide part, which is set on the frame and which contains guide channels for the actuating cables and forms an upper sliding surface of the lateral tracks for the guide element. Advantageously, the guide part is constructed of a U shape that extends over the side parts and the front side of the frame. Preferably, this guide part is produced of plastic, while the frame consists of a sheet metal part.

  • Patent number: 4705316
    Abstract: Wind deflector assembly for vehicles with a sliding or sliding-lifting roof with a wind deflector blade which is connected, by way of at least one hinge, with a carrier part of a roof installation unit and which is swivelable around an axis of the hinge. The hinge has a bearing block attached releasably to the carrier part. The carrier part is provided with guides into which guide parts of the bearing block may be slid. At least one stop is provided for at least a temporary fixation of the bearing block, slid into the guides, with reference to the carrier part. An installation unit equipped with the deflector assembly may be pre-assembled and operationally tested prior to attachment of the unit to the vehicle roof, and can be installed in the vehicle without requiring steps necessitating re-assembly or re-alignment of the deflector assembly.

  • Patent number: 4211365
    Abstract: An auxiliary heater for motor vehicles having a burner assembly for liquid fuels is provided with an electric motor whose shaft is coupled to a drive shaft for auxiliary assemblies, such as a combustion air blower, a fuel pump, a rotational atomizer, or the like, with the drive shaft being mounted at its distal end with respect to the motor and the proximal end of the drive shaft is connected to the motor shaft by way of a flexible elastic coupling. In a preferred embodiment, the combustion air blower is disposed between the motor and the fuel pump and has a hub of flexible elastic material which serves as the coupling element between the motor shaft and the drive shaft. According to a further disclosed feature, the drive shaft extends through the radial bearing and supports a rotational atomizer head at its distal end.

  • Patent number: 3989029
    Abstract: A liquid fuel burning heater for vehicles in which the burner unit has a housing which is surrounded by a radially spaced casing, and the heat exchanger has spaced inner and outer jackets axially aligned with the housing and casing, so that the air flows between them past the latter into the former. The casing and at least the outer jacket of the heat exchanger are integral parts of a unitary casting; the burner unit may be a self-contained subassembly, pre-assembled in its housing.
