Abstract:
A powered sliding device for a slide door slidably attached to a vehicle body, comprising:a wire drum adapted to be coupled with the slide door by way of a wire cable;a motor for rotating the wire drum;a clutch means provided between the wire drum and the motor, said clutch means having a first coupled state for transmitting a closing rotation of the motor to the wire drum, a second coupled state for transmitting an opening rotation of the motor to the wire drum, and an uncoupled state for transmitting neither an opening rotation nor a closing rotation of the drum to the motor, and said clutch means displaceable to the first coupled state by the closing rotation of the motor, and to the second coupled state by the opening rotation of the motor;said clutch means being held in the first coupled state or in the second coupled state when the rotation of the motor is stopped by deenergizing the motor when the clutch means is in the first coupled state or in the second coupled state;said clutch means being returned to the uncoupled state by the opening rotation of the motor by a predetermined amount when the clutch means is in the first coupled state, and said clutch means is returned to the uncoupled state by the closing rotation of the motor by the predetermined amount when the clutch means is in the second coupled state; andwherein said clutch means further has a first brake state for transmitting the closing rotation of the wire drum to the motor, and a second brake state for transmitting the opening rotation of the wire drum to the motor.
