WHEELCHAIR BACKREST

摘要

The invention provides a backrest (20) having pairs of first and second couplings (28, 30, 32, 34) for attaching the backrest to a pair of spaced apart uprights on a wheelchair behing the seat. The backrest is suspended from the first couplings and is located longitudinally by the second couplings which simply engage the uprights and do not require parts to be added to the uprights. The invention also provides a backrest including a tilt mechanism (56, 80, 84) operable to tilt the backrest about the second couplings while reacting with the first couplings to change the location of the backrest relative to the first couplings. Adjustable side supports (150, 152) are also provided.
