Abstract:
A power operating system for opening and closing a vehicle liftgate (12) has a pair of drive units (22, 22') supported on the vehicle roof and connected to the liftgate (12) for opening and closing the liftgate (12). Each drive unit (22, 22') includes a housing (38, 60) having a curved track (80) and a curved gear rack (48) that is bodily movable endwise in the housing (38, 60) and guided by the curved track (80), the rack (48) also serving as the drive link between the housing (38, 60) and the liftgate (12). The combined rack and drive link is extended and retracted by a pinion gear (40) that is journalled interiorly in the housing and engages the teeth of the curved gear rack (48). The pinion gear (40) is rotated by the output shaft (62) of the motor (24), which in turn is fastened to the side of the housing (38, 60). The motor (24) is a reversible electric motor and is adapted to be operably coupled to the vehicle ECU unit and preferably includes an internal transmission and electrically operated clutch controlled by the ECU unit.
Abstract:
The invention relates to the control of the movement of a sliding or swinging and sliding door (1) in its end closing area (x). The door leaf (82) can always move in the direction of closing by means of a free wheel (8) or similar but can only move in the direction of opening when a brake, coupling (9) or other fixing device for the part of the free wheel (8) that is located further away from the door leaf is released. A device for determining the position of the door is also provided. The invention is characterised in that any conventional anti-jamming measures that might be provided in the predetermined end closing area (x) are deactivated, in that as long as the door leaf (2) is located in the end closing area, the power to the door drive (4) and therefore, the closing force exerted on the door leaf, is reduced and in that the brake, coupling (9) or similar acting on part of the free wheel (8) that is located further away from the door leaf is released. The invention also relates to embodiments of this basic idea.
Abstract:
A power sliding door assembly (12) for a motor vehicle comprising a door structure (20) mounted on a motor vehicle for movement between closed and opened positions and a drive assembly (22) mounted on the door structure (20). The drive assembly (22) includes a rotatable gear (24) engageable with a gear track (26) provided on the vehicle. The rotatable gear (24) is drivable in a one direction to effect movement of the door towards the opened position and drivable in an opposite direction to effect movement of the door structure (20) towards the closed position. A drive shaft is coupled with the drive assembly (22) and is constructed and arranged to rotatably drive the rotatable gear (24). A reversible motor is mounted on said door structure (20) and is energizable to drive the drive shaft (36) in a first direction to enable the drive shaft to drive the rotatable gear (24) in the one direction, and energizable to drive the drive shaft (36) in a second direction opposite the first direction to enable the drive shaft (36) to drive the rotatable gear (24) in the opposite direction.
Abstract:
The invention describes an automatic sliding door with at least one panel (1, 1') and with an auxiliary drive unit (14). When the door closes normally, energy is supplied to the auxiliary drive where it is stored. In the event of a power failure and/or simultaneous interruption of the normal drive, this stored energy is then used to open the door. The auxiliary drive (14) is preferably a rubber element which is under tension when the door is closed. In the event of a power failure, a coupling (20) between the drive motor (9, 22) and an actuation device (19) is opened and the rubber element contracts, thus opening the door.
Abstract:
A drive suitable for a door or gate operator mechanism has a motor (1) and a gear box (5). The gear box (5) has a drive disengaging means (29) therein which can be pulled by a chord (7) to effect drive engagement of the motor (1) with the gear box (5). When the chord (7) is next pulled drive disengagement of the motor (1) with the gear box (5) is provided. The arrangement permits a door or gate which is driven by the operator to be manually opened in the event of power failure. The mechanical advantage of the gearbox (5) and the motor (1) on the door or gate is such that the gate cannot be manually opened without the drive being disengaged.

Abstract:
An operator for moving a barrier between closed and open positions mounted on, or close to, the counterbalance for said barrier. The operator is connected to the counterbalance shaft and lifts the barrier by rotating the counterbalance shaft with attached cable drums and thereby takes up cable connected to the bottom of the door. There is an upper cable connected to the top of the door through a cable drum in the operator. A power spring biases the operator cable drum to always take up the upper cable, keeping it wound. The operator cable drum is connected to the motor through a clutch which when engaged allows the operator to pull the door closed. While the door is closing the clutch can be disengaged to allow the operator cable drum to take up and then pay out the upper cable connected to the top of the door as needed.
Abstract:
A control device is used to move a pick-up truck tailgate. The control device comprises a first gear arrangement connected to a drive cup and a second gear arrangement that is connected to a motor for driving the second gear arrangement. The control device also includes a clutch arrangement positioned between the first and second gear arrangements. When the clutch arrangement is in an engaged position, it couples the first gear arrangement and the second gear arrangement to transmit torque to the first gear arrangement and the drive cup. When the clutch arrangement is in the disengaged position, the first and second gear arrangements are not coupled. Optionally, the control device comprises a brake unit to slow or stop movement of the tailgate. The control device can be positioned within the pick-up truck tailgate.
