Abstract: The present invention relates to a ventilated seat having an insert with a seat portion, and having a flow control layer with first and second ports, a spacer having an inlay and a main portion, and a first fluid barrier where the inlay is substantially isolated from the main portion by a fluid-tight boundary. The present invention also relates to a ventilated seat having an insert with a seat portion and having a first flow control layer with at least one port, a first and a second spacer, and a fluid barrier comprising at least one port. The present invention also relates to a ventilated seat with an insert having a seat portion and having a flow control layer with a port and a plurality of flow holes in the seat portion, a spacer, a fluid barrier and at least one conduit with a plurality of flow holes located adjacent to the seat portion of the flow control layer. The seat also may include a fan in fluid communication with the spacer and a fluid conditioning device.

Abstract: A control circuit for a vehicle seat having at least one heating element and at least one fan is provided. The control circuit includes a two-pole switch having two synchronously actuated switch elements. The switch elements are operatively connected to the heating element and the fan to operate the heating element and the fan in a first operating mode wherein only the heating element is active, and a second operating mode wherein both the heating element and the fan are active. When two heating elements are employed, the two heating elements are connected in parallel by the switch elements in the first operating mode and are connected in series by the switch elements in the second operating mode.

Abstract: An air conditioned seat with a padded seat surface (4) and a padded backrest (8) and with a fan (16) arranged beneath the seat surface (4). The fan (16) is connected to an air distribution apparatus (20, 22) in the seat, and includes a flow region (31) that is open to the environment. The flow region (31) is located substantially on the side of the fan (16) facing the seat surface (4). The fan inlet (30) is further environmentally protected by a diffuser (36) located in the flow region (31) and forming a slit opening (40) between a top edge (38) of the diffuser (36) and an underside (28) of the seat.

Abstract: A vehicle seat with a backrest (16) that has a backrest cushion (18) and a rear backrest cover (20), and an air-handling device that is associated with the backrest (16) and is connected to an air distribution device (30, 32) in the seat. The rear backrest cover (20) is at least partially air permeable, and covers at least one passage (27) of the air-handling device (23). The air exchanged between the environment and the air-handling device (23) passes for the most part through the air-permeable regions of the backrest cover (20).

Abstract: A vehicle seat ventilating system comprising at least one fan (4) arranged in the seat (7) and controlled by a central control unit (1) and an electric control unit (3) associated with each fan (4) for actuating the respective fan in response to control signals from the central control unit (1), wherein each electronic control (3) is arranged at the respective fan (4) Thus, each of the fans (4) arranged in the vehicle seat (7) has its own electronic control unit (3) that is located at the fan (4) and is connected to the central seat control unit (1) by a data line (2) that transmits control signals. The power supply currents required to drive the fan (4) are regulated directly in the electronic control unit (3) located at the respective fan (4). Thus, each of the fans (4) arranged in the vehicle seat (7) has its own electronic control unit (3) located at the fan (4) and is connected to the central seat control unit (1) by a data line (2) that transmits control signals.

Abstract: A ventilation device for the seat (2, 3) of a motor vehicle (1) which has an electrically driven fan (3, 5), the vehicle (1) having a solar cell arrangement (8) which, with the vehicle (1) turned off, provides a supply of solar generated power for operation of the fan (3, 5).
