ABSTRACT:
A back rest (10) capable of being mounted on a lift platform of a lifting apparatus has a foot part (12) and, thereon, a slab (14) pivotable about a swivel axle (34), the slab (14) forming the back part. At the rear, there is a transverse supporting wall (44) moulded or attached to the slab (14) and spaced sufficiently apart from the swivel axle (34). Between the supporting wall (44) and the bottom (24) of the foot part (12), there is a transverse piece of hose (16) disposed parallel to the swivel axle (34) and closed at its ends, which is connected to the hydraulic-water system of the lifting apparatus via a manual control valve. When the piece of hose (16) is filled, the slab (14) is raised to an upright position even if the upper part of the user's body is applying a load to the slab (14). When hydraulic water is emptied out in a controlled way, the slab (14) can be adjusted in an infinitely variable manner, passing through various angles of inclination and reaching a position with a flatter angle of inclination, in which an attachment at the rear of the slab (14) comes to rest on the foot part (12).
