the effect of a spring 1 is hinged. The cylinder 8 is controlled by a hydraulic control element 9 for adjustment the ventilation flap 3 with pressure oil.

A shift lever 10 is arranged on the control element 9. This is under the action of a hook-shaped lever 11, the articulated via a connecting rod 17 with a vacuum servomotor 14 associated with the central locking system is connected. The central lock is controlled by means of a vacuum system.

The shift lever 10 is in three positions 12, 12 ', 12 ·' mounted movably up and down on the control element 9 (FIG. 2). In its upper position 12 'is a simultaneously open valve of the control element 9 of the working cylinder 8 to open the flap 5 is applied. The flap opening takes place when the switch lever is pushed up to the intended largest opening width 13 of the flap 3. A short one Pushing up the shift lever causes a smaller opening width. Each release of the shift lever 10 can namely this automatically return to the middle position 12, in which both the valve for opening the ventilation flap 3 as well as another valve to close the ventilation flap are closed. The flap 3 remains in the usual open position because that in the cylinder 8 at pressure oil present in closed valves cannot escape

can, so that the restoring effect of the spring 1 has no effect has.

Pressing the shift lever 10 down into the lower position 12 "triggers the reverse process as just described out. Here, too, the shift lever 10 will return to its central position 12 each time it is released, whereby the two - Not shown - valves in control element 9 are closed and the ventilation flap can be set as desired from the fully open position Ij to the closed position can be.

The above-mentioned activation in the central locking system should automatically ensure that the ventilation flap is closed. I am with the closed flap otherwise centrally locked doors, glove box and luggage compartment lid, To be able to "open" the interior of the hunt, the following measures have been taken:

In the vicinity of the shift lever 10 is - as already mentioned on a fixed car body part, for example on the control element 9 a vacuum servomotor 14- arranged, the reciprocally is applied. Its housing is on two opposite sides 15 and 15 'with a vacuum system connected, which acts on each one of the two sides of a membrane 16, which is arranged in the housing cavity is.

On the housing side 1> 'facing the shift lever 10 protrudes the connecting rod 1'7 fastened to the membrane 16 slidingly out of the housing 14- which is connected to a connecting element 18, approximately the length of the liubweg of the membrane 16 in the housing, is slidably connected. At the free end 18 " of the connecting element 18 is the angle lever 11 with his hinged one end, while the short, hook-shaped bent lever end is directed towards the shift lever 10. the ilinkelhebel 11 is approximately at the approach of the bend 11 'of the iiinkelhebels 11 on a fixed part of the vehicle, for example the dashboard, pivoted »

The front end 17 'of the connecting rod 17 is approximately in bent at right angles to its straight main part and serves as a stop, this end 17 'is in an elongated hole 21 of the connecting element 18 slidably guided «The The length of the elongated hole 21 corresponds approximately to the '.7eg of the membrane 16 in the servomotor 14-.

The connecting element 18 carries approximately in the middle of it outer long sides each one protruding in its plane, one another opposite ear 18 ', in each of which one end of two Springs 19 and 20 engages. The other end of the spring 19 and 20 wraps around the bent end 17 'of the connecting rod 17 between a collar washer fastened on this and the adjacent outer plane of the connecting element 18. These springs 19, 20 act as snap springs, as they already do on the doors of vehicles for separate unlocking

a door. '/ ground these snap springs once overcome by pushing up the shift lever, the shift lever is again free from automatic actuation. During the following central unlocking, the snap springs are overcome in the opposite direction, namely from the diaphragm piston, so that the switch is automatically actuated again when the central locking takes place, i.e. the ventilation flap is closed.

The setup described works as follows:

When leaving the vehicle for a long time, the driver of the ΐ / agens will centrally lock the hunt by locking the driver's door with the help of the vacuum system. The membrane, following the negative pressure acting on the housing side 15 facing away from the control element 9, will bend to this side 15 and thus pull the connecting rod 17 further into the housing 14 - its bent end 17 'moves in the elongated hole of the connecting element 18 and at the end of this movement hits the arch 21 of the elongated hole under the action of a spring. The ifinke! Lever 11 pivots about its fixed bearing U ¹ , so that its front curved end pivots the switching rod 10 into the lower position 12 '. The ventilation flap 3 is closed as a result.

If the driver should open a day door separately,

without affecting the closed state of the other centrally locked openings or their flaps, its seat on Tax recaptured and the need for increased .Fresh air, he can act on the main locking or opening device remove the overall lock and thus open the flap. But it can also, without affecting the main locking or opening system, the Push the switch lever 10 up by hand into the position 12 '. As a result, the 7 / in! Lever 11 swivels around its bearing 11 ' clockwise so that the connecting element 18 is closer to the control element 9 is used. As a result, the opening valve that has become free in the control element 9 becomes a working cylinder 8 is applied and the flap 3 is pivoted into the desired open position.

The device is designed so that after the flap 3 has been opened, the switch lever 10 is released automatically returns to its central position 12. He also takes this as soon as the end of the opening movement deliberately not waited and the shift lever 10 already relieved will. In this process, the rest of the locking system remains uninvolved, so that apart from the flap 5 there is no lock is unlocked. Unlocking a door or the glove box lid from the inside of the meeting also remains without Influence on the closed flap position, for example.
