ABSTRACT:
A split back chair having a generally L-shaped seat member formed of a horizontal section and a vertical section, and separate independently movable right and left back portions. A first flat spring extends between and hingedly connects the back portions to one another and allows the back portions to pivot toward and away from another. A spring assembly connects each of the back portions to the seat member at right and left sides of the chair. Each spring assembly includes a cover plate and a second flat spring, both of which extend between the vertical section of the seat member and one of the back portions. A pair of removable arm rests are attached on the sides of the seat member. The cover plate houses the second flat spring and an end of the arm rests. The first flat spring and spring assemblies create a triflex action which allow the back portions to independently flex toward and away from one another creating a cradling effect from side to side, and allow the back portions to flex rearwardly to a reclined position.
