ABSTRACT:
A chair support structure including a pair of transversely spaced struts maintained in substantially fixed relationship to each other, the axes of the struts being inclined with respect to the horizontal and defining an imaginary surface therebetween, an integral rigid member having two upper end portions spaced from each other and two lower end portions spaced from each other and being inclined oppositely to said struts with respect to the horizontal and positioned intermediate the struts to intersect the surface defined thereby, a first tension member connecting the integral rigid member at its upper end portions with the struts at a position above said intersection, a second tension member connecting the integral rigid member at its lower end portions to the struts near their bottoms, and a third tension member connecting the integral rigid member to the struts above said intersection in a position different from said first tension member to gradually inhibit forward pivoting. Also disclosed is a chair including a seat cushion that tilts relative to the horizontal and a back pivotally connected to a back support to compensate for tilting of the seat cushion.
