ABSTRACT:
An office chair incorporates a lumbar support in the lumbar region of the back of the chair. The support includes an arcuate lumbar support element and a carrier for the element, which is pivotally coupled to the back for movement between positions in which the support element provides respectively maximum and minimum support for the lumbar region of the person using the chair. The carrier can be locked in an adjusted position. The support element is resiliently flexible so that its curvature varies between a maximum in the maximum support position and a minimum in a minimum support position of the lumbar support.
