Abstract: A device (3) for climate control of a motor vehicle seat (20) with a cushion core (22) for the support of a passenger, having an upper air distribution device (25) at the front side (27) of the cushion core (22) facing the passenger to distribute air along the front side (27) of the cushion core (22), and having a lower air distribution device (32) at its rear side (30) facing away from the passenger to distribute air along the rear side (27) of the cushion core (22), having a connecting device (35) to transfer air between the first and second air distribution devices (25, 32). Each of the three devices (25, 32, 35) has an elongated hollow space (37), and at least one support element (14) in the form of a spiral spring is provided in the air-conducting cross-section of at least one such hollow space (37).

Abstract: A climate control device (1) with a heater (5), a ventilation device (7), and with an operating device (3). The operating device includes an operating element (9) that can be switched to at least three different operating states. The operating element (9) has a first and a second electrical resistance device (11, 11?, 13, 13?), the first of which is associated with the heater (5) and the second of which is associated with the ventilation device. The electrical resistance of the two resistance devices (11, 11?, 13, 13?) can be changed simultaneously by actuating the operating element (9).

Abstract: A climate control device for a passenger compartment of a motor vehicle, having a base layer (8), having a cover layer (12) that faces a passenger (96) and is arranged to at least partially overlap the base layer (8), and having an intermediate layer (10) that is arranged between the base layer (8) and the cover layer (12) and that has at least one support element (14) in the form of a spiral spring that holds the base layer (8) and the cover layer (12) apart from one another in order to maintain a hollow space (37) between them. The climate control device has at least one electrical conductor (43), which is arranged in the hollow space (37).

Abstract: An air distribution system (20) for distributing air through a vehicle component such as a vehicle seat pad (6). The system (20) includes an air distribution layer (4) defining a base area and a first layer (2) arranged on the air distribution layer (4). The first layer (2) projects beyond the base area along at least a portion of an edge thereof to form a flange (25). A side of the flange (25) facing towards the air distribution layer (4) includes an adhesion area (5). During assembly, the adhesion area (5) engages the seat pad (6) along a pad elevation (41) surrounding a portion of the recess (35) formed in the seat pad (6) to fix the air distribution system (20) within the seat pad (6).

Abstract: A vehicle seat including at least one pad (12) having an air-permeable surface area (16). In the region of the air-permeable surface area (16) of the pad, an air-permeable heating element (18) is arranged to heat the surface area (16) of the pad. A fan unit (24) blows air through the heating element (18) and the surface area (16) of the pad. A first temperature sensor (26) detects the temperature of the surface area (16) or of the heating element (18). A second temperature sensor (30) detects the temperature of the air aspirated by the fan (24). A fan regulator (32) regulates the volume flow of air as a function of the temperature detected by the second temperature sensor (30).

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: 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.
