Abstract
The apparatus is a biomechanical body support including a substructure, a seat which is supported by said substructure and is tiltable relative to said substructure, a backrest which is coupled to said seat and is tiltable relative to said seat, the tilting axis of the backrest approximately coinciding with the pivotal point of the hip joint of a person resting on said seat, as well as a leg support also tiltably connected to said seat. According to the invention the backrest (14) is slidably mounted on a reversed U-shaped tilting frame (6) arranged behind the backrest, the fixed leg of said frame, which is directed towards the backrest, being hingedly connected to a first point (A) of the seat (15) while the second leg (12) is length-adjustable and is connected to a second point (B) of the seat, the backrest (14) being connected to the seat (15) by an adjusting mechanism (7), the arrangement being such that upon downward pivoting movement of the tilting frame (6) the backrest (14) slides relative to the tilting frame (6) in the direction of the seat (15).
