An improved patient chair includes a seat section, a pivotally attached back support and a removably attached leg support. A manually actuated camming mechanism permits adjustment of the back support between a prone position and a seated position. The leg support is detachable from the seat section to facilitate use of the patient chair construction as a chair.

An improved buckle construction for coupling a flexible strap to a bushing includes a special buckle cooperative with both a strap that fits through a slot in the buckle and a bushing. The strap is positioned in a through slot in the buckle and engages the head of the bushing positioned in a keyhole in the buckle to bias the bushing into a locked position. The strap is maintained in a locked position in the through slot by means of a biased lever which is manually releasable.
