Patent ID: 8899682

Claim:
A chair for positioning an individual with respect to a reference location, comprising: a base portion having one or more leg members connected to a frame, wherein the one or more leg members are angled outwardly from the frame to contact the support surface at at least four locations, the one or more leg members being configured to be movably located on a support surface; a seat portion, mounted to said base portion, and configured to receive said individual thereon; a first mechanism configured to provide rotational movement of said seat portion with respect to said base portion; a second mechanism configured to provide sliding lateral movement of the seat portion with respect to said base portion, the second mechanism movable between a retracted position and an extended position in which the seat portion extends beyond the frame in a direction of the lateral movement and beyond an area bounded by the four locations in a direction of the lateral movement; a locking mechanism releasably engaged to the base and the second mechanism; wherein the first mechanism and the second mechanism are each activated independently of a state of activation of the other, to facilitate movement of the individual from a first position that is located remote from the reference location to a second position that is located adjacent said reference location without the need for movement of the base portion with respect to the support surface; and wherein the locking mechanism is operable to fix the seat portion in multiple seating positions with respect to said base portion between said first position and said second position.
