Abstract
A modular wall proximity reclining/tilt chair (10) is disclosed. The modular wall proximity reclining/tilt chair (10) includes a simplified actuation mechanism (12) which significantly reduces system complexity and weight while providing improved comfort to the seat occupant. The construction is such that the pre-assembled actuation mechanism (12) is integrally suspended from and interdependent with box-like modular frame components (24). In this manner, the frame components (24) can be upholstered prior to final assembly with the actuation mechanism (12).
