ABSTRACT:
The seat back unit has a seat back frame which can be tilted around the tilting axis (11) of the support (21). Movable on the seat back frame (13) is the seat back (25). A linear motor (33) serves to incline the seat back frame (13) together with the seat back (25). With a linear motor (33) the distance between the support (21) and the connecting section (17) of the back frame (13) can be reduced or increased, respectively. A tape (43) extends from a stationary part (45) of the linear motor (33) via the connecting section (17) to the seat back carrier (44). Accordingly, if the seat back frame (13) is tilted towards the rear, the seat back (25) is moved downward together with the arm rests (29) attached to the seat back carrier (44). A stabilizing mechanism (51) keeps the arm rest (29) in a practically horizontal position. Accordingly, on reclining the arms of the user remain always in a practically horizontal position and are finally lowered to a position practically parallel to the body. Therefore there will be never a danger of the arms gliding down from the arm rests (29), so that also a strongly invalid user of the wheelchair will always be in a position to control the control lever (30).
