Embodiment Construction

[0020] figure 1 A vehicle seat 1 of a motor vehicle, not shown in detail here, is shown in a simplified illustration with a seat part 2 and a seat back 3 . The seat portion 2 and the seat back 3 each have a seat surface 4 with which a passenger comes into contact when sitting on the vehicle seat 1 .

[0021] A seat ventilation device 5 is integrated in the seat back 3 , the seat ventilation device 5 comprises a blower 6 and a plurality of ventilation openings 7 formed / arranged in the seat surface 4 of the seat back 3 through which the seat back 3 The ventilation pipe in is connected with blower 6. The blower 6 advantageously has an electric motor 8 for drive, which is operated by a controller 9 . The blower 6 is here designed as a centrifugal blower and the electric motor 8 is designed as a brushless DC motor. An advantageous compromise can thus be achieved between the required installation space, costs and performance of the seat ventilation device 5 .

Abstract

The invention relates to a method for operating a seat ventilation system (5) with at least one blower (6) and at least one blower arranged in a seat surface (4) and connected to the The air vent (7) to which the blower (6) is ventilatedly connected, wherein the blower (6) is controlled to adjust the rated speed, and wherein the rated speed is adjusted according to the current state value (i) of the blower (6), which depends on Depending on the volume flow (V) delivered by the blower (6). It is provided here that the adjusted rotational speed is selected as a function of the current state value (i) from a characteristic field (KF), wherein the characteristic field (KF) is established as a function of predefinable acoustic limit values.

Description
