  • Patent number: 5311210
    Abstract: A combination ergonomic chair and bifurcated QWERTY apparatus integrally defined in the armrests of the chair. The combination apparatus includes a pair of adjustable arms for selectively orienting the armrests with respect to the operator. A standard QWERTY keyboard is bifurcated such that each half of the keyboard is defined on each of separate respective armrests. Each keyboard unit is attached to the armrests via a ball-in-socket arrangement and includes half of a QWERTY keyboard on one side, and a ten key numerical pad on the opposite side. A unique arrangement reduces stress, fatigue and injury associated with data entry work by facilitating proper postures to reduce upper extremity cumulative trauma. Each keyboard unit has a curve surface for provided palmar support to the hand while accessing the keypad. The chair and keyboard apparatus also includes a pair of rotary encoders integrally defined in the keyboard support structure to simulate a mouse.
