Abstract: A process for the production of a cover unit with a seal for vehicle roofs in which a cover part, such as a glass cover part, a cover support and a profile part, having a replacement seal receptacle are inserted in a mold having an upper part and a lower part. The profile part is spaced from the cover part and the support leaving edge gaps which are filled by introducing an elastomer therein to connect this assembly to a cover unit. The profile part is attached and aligned, in a preferred embodiment, by attaching projections on the upper part and/or lower part of the mold depending on its position in the production of the cover unit. A peripheral seal can be molded on the profile part.This peripheral seal can be removed from the profile part, so that the seal receptacle of the profile part can be used to insert a replacement seal.

Abstract: A vehicle roof for closing an aperture in a fixed roof surface comprising a series of strip-like plates. In closing the roof, the plates lie edge to edge to form a flat sheet. The plates are mounted on guide tracks in a roof frame fixed beneath the roof surface around the aperture. Each plate is carried on the guide tracks at two locations, and the plates can be moved rearwards and tilted. In the roof open position, the plates are pivoted upward and lie substantially parallel to one another. The pivoting takes place towards the rear of the aperture as each plate is completing its rearward movement. The plates remain engaged with both guide track locations at all times and this ensures the stability of the assembly. In each case, a drip molding is hinged at least on a part of the plates. The drip moldings are guided to slide along lengthwise guideways, and they take part only in the sliding movements of the respective plates, not their pivoting.

Abstract: A process for cooling the interior of a motor vehicle and a roof system for its performance which has a roof part that can be opened by an electric motor. As a function of the interior temperature and an interior setpoint temperature, an automatic moving of the roof part that can be opened into a first open position takes place, in which a large roof opening is created. Time-dependent or as an alternative to this, when the temperature is less than a lower threshold temperature, an automatic moving of the roof part that can be opened into a second open position takes place, in which a smaller roof opening is created. The process and roof system enable quick removal of a build-up of heat when getting in the vehicle and in the beginning phase of a drive.

Abstract: An interior climate control system in which a vehicle fan of the vehicle's own ventilation device, an openable and closable vehicle opening, such as a roof opening or a window opening, and a heater that can be operated independently of the engine are linked by an operating control circuit into a functional unit so that, when a predetermined, upper temperature limit is exceeded, a control circuit allocated to the operating devices for the openable and closable vehicle opening is controlled and activated, and so that, when the temperature falls below a predetermined, lower limit, the engine-independent heater is controlled and started. A pre-air conditioning operation or a preheating operation in the interior climate control system can be achieved by a remote control device and/or by a preadjustable timer device by the operating control circuit.
