Abstract
A mechanical lumbar system for vehicle seating. The lumbar system may be compact in size so as to require a smaller space within vehicle seating. The lumbar system may be adjustable in 4-ways. The lumbar system may be adjustable in an in and out fashion so as to decrease and increase, respectively, the amount of lumbar support. The lumbar system may be adjustable vertically so as to allow the vertical position of the lumbar support to be moved to accommodate the occupant. The lumbar system may utilize a U-shaped lower bridge member that allows the motors to be positioned vertically higher in the seat back while also allowing the lumbar support to be positioned below the motors. The legs of the lower bridge may extend below the lower frame cross member in the vehicle seat.
