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 device for ventilating a vehicle seat, said device comprising: a cushion () which is elastic with respect to a user contact and which is designed to form a seating surface and/or a contact surface () for the back, said cushion having an air flow channel () which forms an air outlet () in the direction of the seating surface and/or contact surface for the back; a cover unit () designed to at least partially cover the air outlet, the unit being air-permeable, rigid and preferably having a lattice-type construction; and a fan unit () which is associated with the air flow channel and which has an electric motor-driven fan rotor () and a fan housing (), some sections of which housing radially surround the fan rotor. The cover unit and the fan unit are mutually spaced (d) along the air flow channel and preferably are secured to or in the cushion without a direct connection to sections of said cover unit and fan unit. Preferably, a mechanical connection between the cover unit and the fan unit is achieved only by a flexible, rubber-elastic material, especially preferably a foam-type material of the cushion ().

Device for ventilating a vehicle seat and vehicle seat

A mounting apparatus () for mounting a fan arrangement () on a seat (), for example a vehicle seat, features a cylindrical sleeve or installation element () which secures within the seat, and a fan housing () for the fan arrangement or module (), which slides into, and latches within, the cylindrical sleeve (). The fan housing () has a tubular housing part () having a first housing part end () and a second housing part end () located axially opposite it. The fan module () includes a centrally located fan () supported by a plurality of radial struts (), at least one of which serves as a channel () for power supply connecting wires (). Wire pass-through openings (') are configured to permit a partial rotation of the fan module () during installation into the cylindrical sleeve ().

The invention relates to a blower, especially for a personal computer. The air of the invention is to reduce the noise produces by such a blower. To this end, the inventive blower comprises: a) a blower housing ( ) including a guide surface ( ) that defines the exterior limits of a flow channel ( ); b) a hub ( ) that is mounted in the blower housing ( ) so as to be rotatable about an axis of rotation ( ) and having a hub surface ( ) that defines the interior limits of the flow channel ( ); c) a rotary drive ( ) for the hub ( ) which is disposed within the hub ( ); d) the blades ( ) of the hub ( ) are asymmetrically distributed about the periphery of the hub ( ) and are configured as radial blades; and e) the guide surface ( ) and the hub ( ), in the blade zone between the leading edge ( ) of the blade and the trailing edge ( ) of the blade, when looked at in the direction of flow, have a generally conical or slightly curved and widening shape, and the area of cross-section of flow along the flow channel ( ) remains constant or is reduced.
