ARTICULATED CHAIR HAVING UNIVERSAL RECLINING ARMREST SYSTEM
First Claim
1. An armrest system comprising:
- a chair having a seat and a backrest that is adjustable with respect to the seat over a range of motion; and
a first armrest configured to couple to a first portion of the backrest at a first orientation relative to at least one of a surface of the seat and a horizontal plane, the chair being configured to substantially maintain the first orientation of the first armrest throughout the range of motion, the first armrest being configured to be selectively removable from the first portion of the backrest and to couple with a second portion of the backrest, the second portion being configured to hold the first armrest at a second orientation relative to the at least one of the surface of the seat and the horizontal plane, such that the second orientation of the first armrest is substantially maintainable throughout the range of motion.

Abstract
A universal reclining armrest system for use with an articulated examination chair. The system includes an armrest adapter having a universal aperture for receiving a post portion of an armrest assembly. The armrest adapter further includes a splined peg for coupling to a pivoting mechanism of an articulated chair. The pivoting mechanism enables the chair to move throughout an operable range of motion while maintaining a fixed rotational position of an attached armrest adapter. The armrest assembly further includes an adjustable joint to provide 360° of rotational adjustment to the armrest relative to the fixed position of the armrest adapter.
