Abstract

A support structure is provided for attachment to a chair base to support a seat and a backrest. The structure includes a tilt mechanism operable by leaning on an associated backrest to bend a spring link. As a result, both the backrest and seat tilt a predetermined amount. The invention also provides an embodiment in which the tilt mechanism is adjustable so that the user can vary the amount of tilt achieved by leaning on the backrest.
