Abstract
A reclining chair has a base coupled to a chair back. The chair back is adapted to recline from an upright position to a reclined position. To accommodate that reclining motion, the chair back includes a flex zone formed with notches extending through an inner portion of the flex zone. Those notches narrow as the chair back reclines from the upright position to the reclined position. The flex zone also includes an outer portion that is separated from the inner portion by a gap, the outer portion having one or more notches extending through the outer portion. Those notches also narrow as the chair back reclines from the upright position to the reclined position.
