Abstract:
A method for controlling a movement of a window pane of a motor vehicle door immediately after the lowering of the window pane, until there is compensation of the system deficiency of the displacement mechanism caused by the displacement of the window pane into the lowering direction of movement. With a short stroke lowering of the upper edge of a free-standing frameless window pane from a keyed sealing engagement on the bodywork side, a signal is generated through opening of the door and passed to an electronics evaluation unit whereupon the drive of the window lifter is activated in the lowering direction until the window pane has moved from its closed position into a predetermined partially opened position. After closing the vehicle door, as a result of the generation of a further signal, the lowered window pane is automatically closed again. During control of the drive for the purpose of automatically lowering the window pane, a first phase of the drive movement is assigned to compensate the system deficiencies of the window lifting mechanism, and a second phase of the movement is assigned to a path of the window lowering.
Abstract:
A hinged and sliding door assembly for vehicles includes a door surround defining an opening, a door configured for mating with the door surround, and a hinge-and-slide mechanism for supporting, and defining movement of, the door relative to the surround. The hinge-and-slide mechanism has an intermediate element connected to the door by a hinge structure which defines an axis of rotation about which the door rotates relative to the intermediate element. A slide mechanism, associated with the intermediate element and the surround, is configured to define a slide path of the intermediate element relative to the surround. The slide mechanism is further configured to support the intermediate element such that this axis maintains a substantially constant orientation relative to the surround, thereby supporting the door.
Abstract:
A closure assembly includes a track and a slidable and pivotable closure member. The closure member is engaged with the track proximate first and second pivots adjacent the pivotable end of the member, the first and second pivots being interconnected by a multiple segment shaft (for example at least two portions) (for example telescoping) which provides for accurate installation, retention, removal, adjustment and alignment of the first and second pivots in a substantially parallel line for pivotally supporting the closure member so that it may be safely and securely pivoted away from the closure assembly.
Abstract:
A swinging-sliding door for vehicles, particularly for passenger vehicles, includes two door leaves positioned outside and within the wall of the vehicle in a closed state. For the door, a driving device for operating the door leaves includes pivotable, roller carrying levers which swing the door leaves from the closed position into a ready-to-open position; in addition, the driving device exerts a reaction force onto the pivotable roller carrying levers which, in closed position, results in locking them, a driving device includes a single electro-motor and gearing unit positioned laterally above the opening of the door, further having a case and a driving pulley, a traction belt is guided through a deflection pulley and couples the drive pulley to the door leaves via the roller carrying levers; the case has a flange carrying an eccentric control pin engaging a control lever fastened to a door post carrying the pivotable roller-carrying lever, and the control pin in a door closing position being held in a dead center position in a curved contour of the control lever so that the door is safely locked and can neither be opened manually nor by forces of the wind.
Abstract:
A power door operator for transit vehicles utilizing a rodless pneumatic cylinder as a prime mover in opening and closing doors in the sidewall of a transit vehicles. Door movement having a controlled, predetermined door edge force is achieved through mechanical coupling an external piston of the rodless cylinder and vehicle doors through an endless toothed belt. Magnetic coupling between internal and external pistons of the cylinder provide controlled force having a maximum or breakaway value applied to the operated door. A novel reaction lock operated by admission of pressurized air to the cylinder latches or unlatches the operated door in its closed position subsequent or prior to door closing or opening. Control of door motion at the ends of its travel is achieved through the use of a novel differential area internal piston in the pneumatic cylinder. Available internal piston force is modified for predetermined piston positions on approaching either end of the cylinder through the use of a sliding rod contained by the pressure sensitive internal position. Movement of the sliding rod adjust the effective piston area so as to modify available force to controlling door motion.
Abstract:
Concentric tubes, mounted for relative rotation about their common axis, each include radially extending hinge plates. The tubes carry contra-rotational cam slots through which project the ends of a cross-shaft. Bearings on the ends of the cross-shaft engage the milled cam slots. A cylindrical cross roller bearing block mounting the cross-shaft is axially, slidably positioned within the inner tube and is under a biasing force exerted by a compression spring abutting one end of the block. The cam profiles of the slots includes portions at the ends of the slots extending parallel to the rotational axis to lock the inner and outer tubes together at the beginning and end of the stroke with the cam profile controlling the hinge plate acceleration, deceleration, and velocity, in addition to ensuring positive locking of the hinge in plate open and closed position.
