Abstract
An air supply device for a vehicle seat has an air channel arranged on the pressure side of a blower. The channel comprises at least one air discharge opening provided in the upper region of the seat for supplying the head, shoulder and neck area of an occupant of the seat with an adjustable airflow. A heating element is arranged in the air channel between the blower and the air discharge opening. In order to provide the air supply device with an airflow which feels more comfortable to the occupant of the seat, a grid element is arranged inside the air channel between the air discharge opening and the heating element. As a result, the airflow emerging from the air discharge opening is homogenized and slowed down, and this slowing-down allows more heat to be transferred to the airflow from the heating element.
