  • Patent number: 11623555
    Abstract: A roof handle for vehicles comprises a carrier which can be fixed to a vehicle roof and on which a handle body is pivotably mounted, and is pivotable between a holding position, in which a user exerts a substantially downwardly directed weight force on the handle body, and a starting position, in which the handle body is pivoted by a spring into a folded-up position with respect to the vehicle roof, the carrier comprising a molded body made of plastic on which at least one insert made of metal is provided, and the handle body being held on the insert made of metal via bearing elements. As a result, the roof handle can have a low dead weight and be optimally adapted to the geometry of a vehicle roof.

  • Patent number: 11458876
    Abstract: A roof handle for a vehicle has two bearing elements which can be fixed to a roof of a vehicle and on which a handle body is mounted so as to be pivotable between a raised position and a lowered holding position. A line for the power supply is provided on at least one bearing element, which line, in a raised position of the handle body, is connected via contacts to an illuminating means on the handle body. Light can be irradiated via the illuminating means into an optical waveguide. This makes the handle body more visible in poor lighting conditions.

  • Patent number: 5858316
    Abstract: A process and device for removing and oxidizing organic substances from an extracted air stream. The air stream is flowed through a filter which adsorbs the organic material, where the airstream is bypassed around a catalyst until the filter is saturated. At saturation a heater supplies heat to the filter to desorb the organic material. The catalyst is heated by another heater at the desorption period and receives the organic material and extracted air stream to oxidize the organic substances.
