The invalid chair is for mounting on a travel chassis, having foot and back rests folding into roughly the same plane as the seat surface and lockable in this position by inserting pins in holes along a circle round the hinge axis in locking plates. These plates (10,17) are provided for each of the hinges, and a guide cylinder (23) is joined to each of those (17) for the backrest (2). These cylinders fit over the free ends of the seat frame (7), allowing the plates and the hinge end (18) of the backrest to be slid parallel to the seat surface. (DS). |
