Abstract
Abstract A tray table assembly for a chair is disclosed which is adapted for use in a health care environment. The tray table assembly enables a seated occupant or care giver to quickly and conveniently pivot the tray table in various incremental positions throughout a generally horizontal 360° circular path. The tray table assembly includes a main tray assembly pivotally coupled to a mounting arm assembly to facilitate the lateral adjustments of the tray table. Furthermore, the tray table assembly includes a locking mechanism for quickly and conveniently mounting and demounting the tray table assembly from the health care chair. Still further, the tray table assembly includes positioning means for retaining the tray table in the desired position.
