<p>A chair (18) includes a flexible pivot member (54) between seat (22) and back (24). Pivot member (54) includes an upper section engaged with back (24), and a lower section engaged with seat (22). Pivot member (54) is resilient and flexible, to enable back (24) to be pivoted rearwardly relative to seat (22), and to provide a forward bias to back (24). A limit strap (56) is engaged with pivot member (54) for limiting rearward pivoting movement of back (24) relative to seat (22). Limit strap (56) includes an opening (74) which receives a protrusion (64) on pivot member (54). opening (74) is slightly larger than protrusion (64), and an edge of opening (74) engages protrusion (64) when pivot member (54) is flexed, to limit rearward movement of back (24) relative to seat (22).</p> |
