Neck chair with arm rests

Abstract

A system is provided for anatomically accommodating a user during the use of a reclinable chair. Structurally, the system includes a base clamp that is mounted to the chair and that defines a first axis. Further, the system includes an intermediate clamp connected to the base clamp and defining a second axis. Also, the system includes a pivot defining a pivot point. In order to support the arm of a user, an arm rest is connected to the pivot. With the cooperation between the components of the system, the arm rest can be selectively positioned with respect to the chair to anatomically accommodate the user. Specifically, the arm rest is positioned by selectively rotating the pivot about the pivot point, the pivot point about the second axis, and the second axis about the first axis.

       8 . A system as recited in  claim 7  further comprising
 a mechanical means for positioning a second pivot at a predetermined spatial relationship to the chair, with said positioning means being mounted to the chair, and with said second pivot defining a second pivot point and being rotatable about the second pivot point; and   a second arm rest mounted to the second pivot, with said second arm rest being rotatable about the second pivot point to establish an orientation for the second arm rest relative to the chair to anatomically accommodate the user.   
   
   
       9 . A system as recited in  claim 7  wherein the positioning means comprises:
 a base clamp mounted to the chair, said base clamp defining a first axis; and   an intermediate clamp interconnected between the base clamp and the pivot, said intermediate clamp defining a second axis, with said second axis being substantially parallel to the first axis, and with said pivot point being rotatable about the second axis, said second axis being rotatable about the first axis, and said base clamp being movable along the first axis to establish a position and orientation for the arm rest relative to the chair to anatomically accommodate the user.   
   
   
       10 . A system as recited in  claim 7  wherein the chair includes a surface comprising a frame and a covering connected to the frame to support the user, and wherein the system further comprises a means for providing a void in the covering to accommodate the user's face when the user lies facedown on the surface, and a means for adjusting the position of the void in the covering to cooperate with the arm rest to anatomically accommodate the user. 
   
   
       11 . A system as recited in  claim 10  further comprising a tray connected to the back portion of the chair for use by the user when lying facedown on the surface, with said tray being positionable substantially directly below the void in the covering. 
   
   
       12 . A system for anatomically accommodating a user during the use of a chair having a surface for supporting the user, said system comprising:
 a means for providing a void in the surface of the chair to receive the user's face when the user lies facedown on the surface of the chair;   a means for positioning a pivot at a predetermined distance from, and angle to, the void, with said positioning means being mounted to the chair, and with said pivot defining a pivot point and being rotatable about the pivot point; and   an arm rest mounted to the pivot, with said arm rest being rotatable about the pivot point to establish an orientation for the arm rest relative to the void to anatomically accommodate the user.
