Abstract
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.
