ABSTRACT:
A high pressure pumping system for power inflating and power bleeding the lumbar support of a vehicular seat including a high pressure air cell mounted in the back support. A two-position pneumatic switch serves to selectively alternately reverse a motor and pump to inflate the air cell to a predetermined capacity 5 or greater p.s.i., and to manually deflate the air cell through a bleed valve until the system pressure is lower than the set pressure of a pressure cut-off switch whereupon the motor and pump power bleed the system.
