Abstract

An adjustable lumbar support for a seat having a seat frame is disclosed, the adjustable lumbar support including a floating support plate for providing an amount of lumbar support to a lumbar region of a seat, the support plate having a front surface and a rear surface, the floating support plate being attached to the seat frame via springs, the provided lumbar support defining an apex. A first actuator assembly and a second actuator assembly are each operatively connected to the floating support plate via respective first and second cables, the first and second cables being spaced from each other substantially vertically within the floating support plate, the first and second actuator assemblies for selectively actuating the respective cables to selectively move the apex substantially vertically and substantially horizontally forward and back relative to the seat frame. A secondary support plate may be provided, and may be hingedly and/or floatingly mounted. Adjustability may be achieved in terms of back and forth (horizontally), up and down (vertically) and by the vertical height of the lumbar support profile. Accordingly, in some aspects the present invention provides a 'six-way' adjustable lumbar support.
