Device for providing a pneumatic pressure medium by means of a pressure medium source for at least one pressure medium chamber of a vehicle seat of a motor vehicle in particular

A method for providing a pneumatic pressure medium for at least one pressure medium chamber of a vehicle seat of a motor vehicle, which comprises the steps of:

• providing a device including:
• a housing containing at least one valve and a printed circuit board carrying a controller;
• a pressure medium source for the pneumatic pressure medium including a motor and a pump driven by the motor, the pump being integrally formed with the motor;
• at least a portion of the motor being disposed in the housing and resting against the printed circuit board, the motor having a direct mechanical connection to the printed circuit board inside the housing;
• the motor being disposed between the printed circuit board and the pump;
• a pressure medium line extending between the pressure medium source and the at least one valve, the pressure medium line running from the pump, along a side of the motor parallel to a rotor of the motor, into the housing and to the at least one valve;
• at least one connection between the at least one valve and the pressure medium chamber;
• and
• the device having only a single electrical connection to a seat cable harness;
• and
• actuating the device to provide the pneumatic pressure medium for the at least one pressure medium chamber.

A device for providing a pneumatic pressure medium to a pressure medium chamber, the device comprising:

• a housing containing at least one valve and a printed circuit board carrying a controller;
• a pressure medium source for the pneumatic pressure medium including a motor and a pump driven by said motor, said pump being integrally formed with said motor;
• said motor being disposed between said printed circuit board and said pump;
• a pressure medium line extending between said pressure medium source and said at least one valve, said pressure medium line running from said pump, along a side of said motor parallel to a rotor of said motor, into said housing and to said at least one valve;
• at least one connection between said at least one valve and the pressure medium chamber;
• and
• the device having only a single electrical connection to a seat cable harness.
