1. A seat assembly for an automotive vehicle, the seat assembly comprising:
a cushion and a backrest, one of the cushion and the backrest including an inflatable bladder therein; a high pressure source coupled to the bladder to provide a high relative pressure to the bladder causing inflation of the bladder; a low pressure source coupled to the bladder to provide a low relative pressure to the bladder causing deflation of the bladder; a micro-valve assembly connected between the bladder and the high and low pressure sources, the micro-valve assembly having a first housing cooperating with a first micro-valve sub-assembly to define a high pressure supply chamber that is coupled to a high pressure air source, the first housing also cooperating with a second micro-valve sub-assembly to define a low pressure supply chamber that is coupled to a low pressure air source, a second housing cooperating with both the first and second micro-valve subassemblies to define a primary pressure chamber, an outlet port from the primary pressure chamber being coupled to the inflatable bladder, each of the micro-valve sub-assemblies further comprising valve port extending therethrough and having a MEMs micro-valve positioned in the valve port, the micro-valve sub-assemblies being mounted to a printed circuit board (PCB) that is positioned in the primary pressure chamber and has an air pressure sensor mounted thereon, the PC board being connected to the MEMs micro-valves by solderless connections and the MEMs micro-valves being actuatable between an open and closed positions where fluid communication between the primary pressure chamber and high and low pressure supply chambers is respectively permitted and prohibited. |
