An air supply device is provided for a vehicle seat of an open-top motor vehicle having at least one air outflow opening which is provided in the upper region of the vehicle seat and via which an airstream can be applied to the head area, shoulder area and nape area of the sitting vehicle occupant in order to reduce undesired draft phenomenon. The airstream can be regulated by way of a control device. In order to provide improved comfort for the sitting vehicle occupant when driving with the top open, the airstream is adjusted, when the air supply device is switched on, by way of the control device as a function of an automatically sensed external parameter value or of a predefined value selectable by the sitting vehicle occupant, to an assigned basic value, starting from which the further adjustment of the airstream is carried out as a function of an automatically sensed further parameter value.

The invention claimed is: 1. A vehicle seat of an open-top motor vehicle having an air supply device and at least one air outflow opening of the air supply device, which is provided in an upper region of the vehicle seat, via which an airstream generated by a blower can be applied to a sitting vehicle occupant head area, shoulder area and nape area in order to reduce undesired draught phenomenon, wherein the airstream can be regulated by means of a control device of the air supply device, wherein, when the blower of the air supply device is switched on, the airstream is adjusted by means of the control device as a function of a predefined value, selectable by the sitting vehicle occupant, to an assigned basic value, starting from which the further adjustment of the airstream is carried out as a function of the velocity of the motor vehicle, and wherein said control device changes said assigned basic value depending on a sensed external temperature. 2. The vehicle seat as claimed in claim 1, wherein the basic value of the airstream is determined by an assigned fan speed of the blower and an assigned heating power of a heating element. 3. The vehicle seat as claimed in claim 2, wherein during the further adjustment of the airstream, the fan speed of a blower can be adjusted as a function of the velocity of the motor vehicle. 4. The vehicle seat of claim 3, wherein the external parameter value for adjusting the basic value is newly determined at regular intervals during the driving operation. 5. The vehicle seat of claim 2, wherein the external parameter value for adjusting the basic value is newly determined at regular intervals during the driving operation. 6. The vehicle seat as claimed in claim 1, wherein during the further adjustment of the airstream, the fan speed of a blower can be adjusted as a function of the velocity of the motor vehicle. 7. The vehicle seat of claim 6, wherein the external parameter value for adjusting the basic value is newly determined at regular intervals during the driving operation. 8. The vehicle seat of claim 1, wherein the basic value of the airstream can be adjusted in one of a plurality of power levels. 9. The vehicle seat of claim 8, wherein during the further adjustment of the airstream the fan speed of a blower can be adjusted as a function of the velocity of the motor vehicle. 10. The vehicle seat of claim 1, wherein the external parameter value for adjusting the basic value is newly determined at regular intervals during the driving operation. 11. The vehicle seat as claimed in claim 1, wherein the basic value of the airstream can be adjusted in one of a plurality of power levels. 12. The vehicle seat of claim 11, wherein the external parameter value for adjusting the basic value is newly determined at regular intervals during the driving operation. 13. The vehicle seat as claimed in claim 1, wherein during the further adjustment of the airstream the fan speed of a blower can be adjusted as a function of the velocity of the motor vehicle. 14. The vehicle seat of claim 13, wherein the external parameter value for adjusting the basic value is newly determined at regular intervals during the driving operation. 15. The vehicle seat as claimed in claim 1, wherein the external parameter value for adjusting the basic value is newly determined at regular intervals during the driving operation. 16. An air supply arrangement for supplying a draught reducing airstream to a vehicle occupant neck area during driving of an open top motor vehicle comprising: an airstream supply system operable to blow an airstream adjacent the vehicle occupant neck area, manually operable selection means for selecting one of a plurality of basic airstream parameters, and a control means operable to further adjust the selected one of the plurality of basic airstream parameters as a function of vehicle velocity and change the parameter selected depending on a sensed external temperature. 17. An air supply arrangement according to claim 16, wherein said basic airstream parameters include airstream velocity and airstream temperature. 18. An air supply arrangement according to claim 17, wherein the control means is operable to change the velocity of the airstream linearly as a function of the vehicle speed. 19. An air supply arrangement according to claim 17, wherein the control means is operable to change the velocity of the airstream non-linearly as a function of the vehicle speed. 20. An air supply arrangement according to claim 17, wherein the control means is operable to change the temperature of the airstream linearly as a function of the vehicle speed. 21. An air supply arrangement according to claim 17, wherein the control means is operable to change the temperature of the airstream non-linearly as a function of the vehicle speed. 22. An air supply arrangement according to claim 17, wherein the control means is operable to change the temperature and the velocity of the airstream as a function of the vehicle speed. 23. An air supply arrangement according to claim 16, wherein the airstream supply system includes a blower and a heater, and wherein said selection means and control means are operable to select and control the blower and heater.
