A device for ventilating a vehicle seat having a cushion () which is resilient with respect to user contact and which is constructed to form a seat and/or back contact face () and which has an air flow channel () which forms an air outlet () in the direction toward the seat or back contact face, an air-permeable covering unit () which is formed in order to at least partially cover the air outlet and which is preferably constructed so as to be rigid and/or grid-like, and a ventilator rotor () which is associated with the air flow channel and which is driven in an electro-motive manner and a ventilator unit () which has a ventilator housing () which at least partially radially surrounds the ventilator rotor, characterized in that the covering unit and the ventilator unit are fixed on or in the cushion with spacing from each other along the air flow channel and without direct connection of portions of the covering unit and the ventilator unit, and the ventilator housing has at the peripheral and/or outer side first fixing means () which are constructed in order to secure the ventilator unit in the air flow channel by engaging in and/or in order to cooperate with second fixing means () which are provided on or in an inner wall portion of the air flow channel.

Device for ventilating a vehicle seat and use of said device for a passenger vehicle seat

A miniature fan arrangement has a fan () including an electronically commutated drive motor (), a first circuit board () associated with said motor, and a fan housing (). The fan also has a mounting part arranged radially outside the fan housing (), and has a membrane (), made of an elastic material, that elastically connects the fan housing () and the mounting part () to one another. A second circuit board () is arranged between the mounting part () and the fan housing () and is electrically connected to the first circuit board (). The structure provides space for additional motor control components, particularly in small-sized motors.
