Abstract: A chair canopy 12 for a collapsible chair 10, the chair incorporating a collapsible frame with rear uprights 14a,14b. The canopy 12 includes a fabric rear panel 22, and overhead section 26 with front valance 32 and sides 34a,34b. The fabric is supported on a canopy frame having rear uprights 18a,18b slidably attached to the rear uprights of the chair, and front extension members 38a,38b pivotably attached to the rear uprights 18a,18b. Brackets 20a,20b mount the canopy support frame to the chair frame. The brackets have releasable adjustment means to allow the canopy uprights to slide downward for stowage or upright when erecting the canopy. The adjustment means locking the canopy uprights in place at a selected position. The canopy support frame, in use, collapses with collapsing of the chair frame or storage, and opens out when erecting the chair for use.
