Abstract
A wheelchair seat assembly (16) including a seat (30,36), and back rest assembly (49). Back rest assembly (49) includes lateral pelvic supports (52) for carrying pelvic bolster pads (62), an outer shell piece (50) and an inner shell piece (28) adjustably secured to each other, torso supports (76) and a head rest assembly (88). Outer shell piece (50) has a deep concave shape while inner shell piece (28) has a shallow concave shape, which creates a gap (120). Gap (120) provides space for receiving torso supports (76) and head rest assembly (88) in a manner that these two components can be adjusted without interfering with the back rest cushion and without causing discomfort for the user.
