Lumbar support system for a vehicle seat assembly

A vehicle seat assembly comprising:

• a seat back;
• a seat bottom coupled to said seat back;
• and
• a lumbar support system coupled to at least one of said seat back and said seat bottom, said lumbar support system having:
• at least one air cell mounted to at least one of said seat back and said seat bottom;
• a pump fluidly connected to said at least one air cell to selectively inflate said at least one air cell, and said pump having an electrical input;
• and
• a valve fluidly connected between said pump and said at least one air cell with said valve having:
• a body defining a pair of cavities corresponding with each one of said at least one air cell;
• an inflate plunger movable in one of said cavities to selectively open said cavity;
• a deflate plunger movable in the other of said cavities to selectively open the other of said cavities;
• an actuator movably coupled to said body between a first operational position to move said inflate plunger to open said cavity such that said pump fluidly communicates with said at least one air cell to inflate said at least one air cell, and a second operational position to move said deflate plunger to open the other of said cavities such that said at least one air cell fluidly communicates with the atmosphere to deflate said at least one air cell;
• and
• an electrical switch coupled to said electrical input of said pump and closed when said actuator is moved to any one of said first and second operational positions.
