DRIVE ARRANGEMENT FOR MOTORIZED MOVEMENT OF A MOTOR VEHICLE DOOR OR THE LIKE
First Claim
1. Drive arrangement for motorized movement of a motor vehicle door coupled to a motor vehicle body around a pivot axis, comprising:
- at least one drive having a motor unit and a gear connected downstream of the motor unit for producing linear drive movement, wherein the motor unit is self-locking and the gear is not self locking, and a clutch connected between the motor unit and the gear, wherein the clutch is movable between an engaged state, a released state, and an intermediate engaged state, wherein when the clutch is moved into the engaged state the motor unit is coupled to the vehicle door and when the motor unit is turned off manual movement of the vehicle door is blocked, wherein when the clutch is moved into the released state the motor unit is operationally disconnected from the vehicle door, and wherein when the clutch is moved into the intermediate engaged state, the drive has a reduced transmission moment and a reduced transmission force so that the vehicle door is maintained in its current position at any time by self-locking of the motor unit and is movable by manual actuation with a predetermined minimum actuation force.

Abstract
A drive arrangement is provided for motorized pivotal movement of a vehicle door. The drive has a self-locking motor unit, a gear connected downstream of the motor unit for producing linear drive movement, and a clutch connected therebetween. The clutch can be moved into an engaged state in which the motor unit for nominal operation is engaged to the vehicle door. When the motor unit is turned off, manual movement of the vehicle door is blocked. The clutch can be moved into a released state in which the motor unit is separated from the vehicle door in terms of drive engineering. The clutch can be moved into the intermediate engaged state with reduced transmission moment and force so that the vehicle door is kept in its current position at any time by self-locking of the motor unit, but can be moved by manual actuation with a minimum actuation force.

20. Drive arrangement for motorized movement of a motor vehicle door coupled to a motor vehicle body around a pivot axis, comprising:
-
at least one drive having a motor unit, a clutch and a spindle-spindle nut gear, each connected in succession downstream of the motor unit for producing linear drive movement, wherein the motor unit is self-locking and the gear is not self locking, wherein the clutch is movable between an engaged state, a released state, and an intermediate engaged state, wherein when the clutch is moved into the engaged state the motor unit is coupled to the vehicle door and when the motor unit is turned off manual movement of the vehicle door is blocked, wherein when the clutch is moved into the released state the motor unit is operationally disconnected from the vehicle door, and wherein when the clutch is moved into the intermediate engaged state, the drive has a reduced transmission moment and a reduced transmission force so that the vehicle door is maintained in its current position at any time by self-locking of the motor unit and is movable by manual actuation with a predetermined minimum actuation force.
