<p>The seat has an active support element (30) comprising a rib pair like structure, which is formed of stiffened bars (23) and elastic bars (24). The thickness of the bars (23) is larger than the thickness of the bars (24), and the bars (23) are connected with arms (21) in extreme regions. The support element contains an actuator (20), such that force is guided on the arms by the actuator in order to move an original contour (27) of the support element to a torso-shaped target contour (28).</p> |
