ABSTRACT:
An emergency mechanism is incorporated in a powered back door closing device of a motor vehicle. During the time when, with the aid of a driving mechanism, a drawing mechanism of the door closing device is pulling down the back door through a striker secured thereto, the emergency mechanism forces a locking plate of the closing device to pivot from a locking position to an unlocking position thereby to release the striker from the drawing mechanism. The emergency mechanism comprises a cam member which is powered by the drive mechanism and rotatable about its axis in both directions; and a cam follower member which is pivotally connected to the locking plate. The cam follower member is actuated by the cam member in such a manner that when the cam member is rotated in one direction, the cam follower member forces the locking plate to keep the locking position and when the cam member is rotated in the other direction, the cam follower member forces the locking plate to pivot from the locking position to the unlocking position.
