Abstract:
An openable motor vehicle roof with a movable roof element which at least partially clears a roof opening bounded by a body-mounted frame component in the area of which a seal element is located and against which the roof element rests when the roof opening is closed. An electric motor drive for moving the roof element is monitored and which is turned off and optionally reversed, when a interfering body is detected between the roof element and the edge area of the roof opening. A stop surface is provided on the roof element for detecting an interfering body, and the motor vehicle roof is made such that, if there is a interfering body between the edge area of the roof opening and the roof element when the roof opening is being closed, the stop surface comes into contact with the interfering body before the roof element engages the seal element.
Abstract:
A process for producing an arched pane arrangement for a motor vehicle, using a flexible die (24), a plastic film (22) being pressed onto the arched glass pane (18) in order to form a film combination (26) and the film combination being subjected to heat treatment at an pressure which is below atmospheric pressure in order to laminate the plastic film onto the pane. The die (24) is thin glass or a metal foil with a layer thickness of less than 1 mm each.
Abstract:
A motor vehicle roof with a roof plate which has a transparent plastic area to which a peripheral plastic edge is molded which is used especially as a cover visor and which extends downward. Furthermore, the roof plate has a nontransparent area with a holding frame for a functional element molded onto a bottom thereof.
Abstract:
A cold and/or heat accumulator with a plurality of carrier elements which are charged with a cold or heat storage medium, and with at least one heat exchanger which is designed to have a heat transfer medium flow through it in order to cause heat exchange between the cold or heat storage medium and the heat transfer medium. The at least one heat exchanger has a serpentine hollow section, and carrier elements are provided between the legs of the loops of the serpentine hollow section. Two heat exchangers can be provided with the loops of the serpentine hollow section one heat exchanger being interspersed with those of the serpentine hollow section of the other heat exchanger. Preferably, the carrier elements are made of a porous metal foam, and the inlet and outlet for the heat transfer medium are located together at a bottom area at one side of the accumulator.

Abstract:
A motor vehicle roof with a wind deflector element (20) which can be raised with its rear edge area (16) and a covering arrangement which is located behind the wind deflector element for selective joint closing and at least partial clearance of a roof opening, the wind deflector element having a spoiler body (10) for preventing unwanted air flow noise when the covering arrangement is open. The spoiler body (10) is foamed onto the wind deflector element (20) via a peripheral foaming production process.
Abstract:
A fuel cell system which has a high temperature fuel cell stack (1) with current diverters (5) and a reformer and/or an afterburner (6), the current diverters (5) being connected with low temperature connecting elements (10) for current delivery. The current diverters (5) are in thermal contact with the reformer and/or afterburner (6) between the high temperature fuel cell stack (1) and the low temperature connecting elements (10). The thermal contact prevents cooling of the HTFC stack 1 on its ends in the vicinity of the connecting points of the current diverters (5) and ensures effective conversion and uniform transport of the fuel.
Abstract:
A process and tool for producing a composite body part for a motor vehicle, especially for producing a roof module, the tool having a first tool part and a second tool part which are movable relative to one another. The outer skin is inserted in the first tool part, at least part of the peripheral edge area of the side of the outer skin facing the first tool part being moved into sealing contact with a seal arrangement which is provided on the first tool part, plastic material is applied to the side of the outer skin facing away from the first tool part, the second tool part provision shaping the plastic material, and the composite body part being released from the seal arrangement and removed from the tool.
Abstract:
A process and device for determination of the lambda value (λactual) of reformate (10) which is to be supplied to a fuel cell stack (12), by determining the lambda value (λactual) of the no-load voltage (U0) of the voltage on at least one fuel cell element (14). Furthermore, a process and device for lambda control of a reformer, utilizes the process and device for determining the lambda value to controller an actuator of a lambda-controlled reformer (16) for reaction of at least fuel (20) and air (22) into reformate (10), the reformer being connected to a fuel cell stack (12) to supply reformate (10) form the reformer (16) to the fuel stack (12).
Abstract:
A cover for an opening in the roof surface of a motor vehicle including a glass pane which is provided with peripheral foam at its bottom surface in the edge area at least over a part of the periphery. On the edge of the peripheral foam which points toward the middle of the glass pane, an undercut is formed between the bottom surface of the glass pane and the peripheral foam, the undercut extending at least 3 mm into the peripheral foam. A method for manufacturing such a cover is also provided.
