Abstract
The present invention discloses an air supply mechanism for a vehicle seat (), and a method for the operation thereof. The air supply mechanism comprises a control device (), for driving a fan () and a heating element () connected downstream of the fan (). When the air supply mechanism is switched on, the control device () switches on a heating element () and at the same time carries out a starting control of a fan () in such a manner that the fan () 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.
