A folding chair has a frame member 10 presenting a pair of front legs 14 and a chair back 18 interconnected by pivot members 22. Each of the latter pivotally mounts a rear leg 30 of a frame member 32 which has a cross-member 36 (FIGURE 5). A seat 40 is pivotally interconnected to the frame member 32 by way of the cross-member 36, and is also pivotally connected to a pair of collars 62 which locate on respective ones of the front legs 14. A stop member 70 is provided on each front leg 14 for engagement by the respective collar 62. When the chair is moved from the in-use position to a storage position, upward movement of the front edge of the seat 40 is permitted by movement upwardly of the collars 62 on the legs 14. While in the in-use position, any downward load applied to the seat causes closer engagement of the collars 62 with the stops 70, thereby increasing the rigidity of the chair. |
