ABSTRACT:
A posture alignment seat shell for supporting and passively restraining a person seated therein includes a horizontal seat portion and an upstanding back portion formed from resilient material to define a one-piece unit. The upstanding back portion includes a lower back part connected to the seat portion, an upper back part above the lower back part and slanting forwardly thereform, and lateral side parts at opposite sides of the upstanding portion extending forwardly therefrom to prevent side movement of a person sitting thereon. The shell includes flexible strap means for pulling the upstanding back portion downward relative to the seat portion and adjusting the angular position of the back portion. The shell further includes strap means for securing the shell to a chair and strap means for pulling the top segment of the upper part downward and selectively adjusting the height thereof. The shell has non-rigid internal and external strap means to distribute pressure created by the adjusting strap means and prevent tearing of the resilient shell material.
