ABSTRACT OF THE DISCLOSURE. The invention relates to a seat having a movable lumbar support. An arcuate lumbar support is mounted on a back rest frame of the seat by a mechanism which is operable to move the lumbar support forwards or backwards or to tilt the lumbar support as its axis moves vertical to effect a rolling action thereby to raise or lower the level at which it supports a seat occupant. A screwthread in the mechanism is spring-supported to reduce shock applied by the lumbar support. - 1 -
