摘要：The present invention discloses an air supply mechanism for a vehicle seat ( 12 ), and a method for the operation thereof. The air supply mechanism comprises a control device ( 24 ), for driving a fan ( 38 ) and a heating element ( 39 ) connected downstream of the fan ( 38 ). When the air supply mechanism is switched on, the control device ( 24 ) switches on a heating element ( 39 ) and at the same time carries out a starting control of a fan ( 38 ) in such a manner that the fan ( 38 ) starts and is operated at minimum blower speed for a predetermined period of time before the blower speed is raised to a predetermined working point and subsequently the blower speed is regulated as a function of the driving speed. In this manner, a seat occupant does not experience an initial sensation of draft due to a powerful discharge of relatively cold air but rather experiences a pleasant warmth even directly after the mechanism is switched on.
