Abstract

A seat backrest having a contourable upholstered portion (not shown) supported by a rigid frame portion (116) includes means to produce a desired supporting contour in the lumbar region of the seat occupant. The contour-producing means includes a lumbar pad (122), a pair of link members (124) connecting the lumbar pad to the frame, and a double threaded shaft means (126) operable via a knob (128) by a seated occupant from the side of the backrest for moving and holding the link members in an infinite number of fixed positions forward of the frame. A second knob (130) allows the occupant to adjust the rake of the pad (122).
