ABSTRACT:
A seat assembly has a seat frame tiltably supporting a back frame for movement about an axis parallel to the intersection of planes parallel to the seat and back frames, and has an adjusting mechanism for controlling the degree of tilt from a position to the side of and exterior to the seat frame. The adjusting mechanism includes a tilt adjustment slide movable in a channel provided in the side of the seat frame and having a groove therein oblique to the direction of movement of the slide. The slot engages a stud mounted in the back frame and movement of the slide towards and away from the axis of tilt causes the stud to move relative to the channel resulting in movement of the back frame relative to the seat frame.
