  • Publication number: 20240131967
    Abstract: It is provided an adjustment device for a vehicle seat, comprising an output element to which a drive torque can be transferred, and a brake assembly for locking the output element and absorbing, via at least two brake elements adjustably mounted in a brake housing of the brake assembly, forces applied to the output element on the output side, wherein locking, provided via the brake assembly, of the output element can be released in order to rotate the output element in a direction of rotation when a drive torque is applied on the drive side, and, in order to lock the output element, the brake elements are in a locking position in which, when forces are applied on the output side via the output element and are acting in a direction of rotation, at least one of the brake elements bears frictionally against a brake surface of the brake housing.

  • Publication number: 20240072280
    Abstract: The present invention relates to a method for starting a fuel cell stack at temperatures below the freezing point of a reaction product produced during the reaction between an anode-side fuel and a cathode-side fuel. The fuel cell stack comprises a plurality of individual cells having at least one internal cell which is arranged in the stacking direction in the interior of the fuel cell stack and an edge cell which is arranged in the stacking direction at the edge of the fuel cell stack. The fuel cell stack is connected to a cooling circuit having cooling fluid for cooling the fuel cell stack, which cooling fluid can be conducted through the fuel cell stack by a pump arranged in the cooling circuit.

  • Publication number: 20220024419
    Abstract: An arrangement of a separate functional element of a washing fluid reservoir on a corresponding fixing portion of a structural component of a motor vehicle, wherein the fixing portion is at least partially formed from a plastics material, and wherein an opening is formed in the fixing portion in such a manner that an insertion portion of the functional element can be brought into a final installation position by insertion and sliding and/or rotation in a direction transverse to the depth direction of the opening, wherein, in the final installation position, the functional element is positively fixed in relation to the structural component, as viewed in the depth direction of the opening. The invention also relates to a motor vehicle having such an arrangement, to a filling nozzle for a washing fluid reservoir, to a motor vehicle hood latch support with a fixing portion, and to a method for installing a functional element on a fixing portion.

  • Publication number: 20080313798
    Abstract: A portable toilet has a cabin, a water closet in the cabin, a light-transmitting roof upwardly closing the cabin and having an outer edge, and a vent pipe projecting upward through the roof. A light fixture for the toilet has a housing adapted to fit in an installed position against an outer face of the roof and having a throughgoing hole fittable over the vent pipe and a side turned toward the roof. A light source in the housing is energizeable to emit light from the side through the roof and into the cabin. A latch formation on the housing is engageable with the rim to secure the housing to the roof.
