First Claim
Patent Images
1. An occupant support system for supporting an occupant, the support system comprising:
- a frame;
an articulable assembly comprising an upper body section; and
a motion control system configured to substantially simultaneously (i) rotate the upper body section about an axis by an amount Δ
α
relative to the frame from a lowered position generally parallel to the frame to a raised position, (ii) translate the upper body section along the frame by an amount Δ
CS, and (iii) translate a panel of the upper body section by an amount Δ
BS in a direction upwardly away from the frame and parallel to left and right rails of the upper body section, both Δ
BS and Δ
CS increasing as Δ
α
increases, wherein the panel is at a fixed position and cannot be moved relative to the left and right rails when the upper body section is stationary in the lowered position.

Abstract
An occupant support system for supporting an occupant comprises a frame, an articulable assembly which includes an upper body section, and a motion control system arranged to rotate the upper body section by an amount Δα relative to the frame, to translate the upper body section along the frame by an amount ΔCS, and to translate the upper body section by an amount ΔBS in a direction parallel to the upper body section. Both ΔBS and ΔCS are a function of Δα.
