An actuator, especially for seat adjusting devices with at least one electrical engine having subordinated reduction gear and a disconnecting device for manual operation. The generic actuator is provided with a disconnecting device that can be used in all operating processes in a large number of different applications and that guarantees reliable functioning of the disconnecting device without being over-dimensioned and thus uneconomical. The disconnecting device has a coupling insertion spring which determines the release force of the disconnecting device and a reset spring is provided which resets an actuating device.

(1) Field of the Invention
The invention is related to an actuator, especially for seat adjusting devices having at least one electric motor with a subordinate reduction gear and a disconnecting device for manual operation.
(2) Description of the Related Art
A design model of the invention is described in greater detail in the following pages with the help of the drawing. The following figures are displayed:
FIG. 1 is a perspective view of a disconnecting device according to the state of the prior art,
FIG. 2 is a perspective view of an actuator with a corresponding disconnecting device according to the state of the prior art,
In describing preferred embodiments of the present invention illustrated in the drawings, specific terminology is employed for the sake of clarity. However, the invention is not intended to be limited to the specific terminology so selected, and it is to be understood that each specific element includes all technical equivalents that operate in a similar manner to accomplish a similar purpose.
The protective scope of the invention is not limited to the displayed example, because it is possible to think in terms of a large number of alternative design models that also have different gear or coupling arrangements.
FIG. 3a illustrates a schematic representation of a disconnecting device 4 according to the invention in a normal operation condition in which an actuating means 30 is in its normal position and the coupling that can be designed according to the state of the art, is locked. The actuating means 30 is connected to a traction lever 11 through a traction rope 27 of a Bowden control cable 10, where the traction lever 11 is in a non-working position through a reset spring 33 that is guided from the traction rope 27. The traction lever 11 is mounted on a coupling shaft 18 of the disconnecting device 4 around a swivel axis 19, so that it can swivel. A drive lever 28 is stiffly fixed on the coupling shaft 18. The coupling shaft 18 is mounted around the swivel axis 19 with the help of the drive lever 28 in such a way that it can swivel. The bearing positions (not shown here) are located in a housing of the actuator. The traction lever 11 can be swiveled against the drive lever 28.
