  • Patent number: 7302953
    Abstract: In a built-in ashtray, when the cigarette lighter is fitted into a swiveled-up holder, without any special locking mechanism for the holder, an automatic sliding of the ashtray into its closed position is avoided. A spring has a progressive characteristic spring curve such that the spring force, which acts upon the ashtray in its moved-out operative position and presses the ashtray toward the outside, is greater than the oppositely directed force component of the operating force acting in the plane of the spring force during the inserting or operating of the cigarette lighter.

  • Patent number: 6902472
    Abstract: A control panel arrangement is provided for a motor vehicle in which the control panel arrangement includes a lower part and an upper part between which a first and second air circulation channel are constructed. The channels extend at least in some segments approximately transversely to the vehicle direction and run at least regionally parallel to each other and are separated from each other by a channel wall and furthermore lead to first and second air outlets arranged at least in the region of lateral ends of the control panel arrangement. The second air circulation channel is continued upstream from the second air outlet allocated to it at least in segments inside the first air circulation channel with a channel extension for a compact design of the control panel arrangement.

  • Publication number: 20040134503
    Abstract: A built-in ashtray for a motor vehicle has a housing which has a guide by means of which an ashtray is displaceably in a drawer-type manner disposed in the housing. The ashtray also has a holder for a cigarette lighter which is mounted on the ashtray so that it can be moved into an operative position projecting upward from the ashtray. The built-in ashtray is equipped with a driving device which moves the holder during the displacement of the ashtray out of the housing into the operative position upward and, during the displacement into the housing, in a downward manner Furthermore, a spring is arranged between the housing and a rearward area of the ashtray, which spring changes the ashtray after the release of a locking from a moved-in closed position into a moved-out operative position.
