<p>At least one part (6) of seat's surface (2) can tip around at least one main axis relative to its base. The main axis runs from the front (3) to the rear (4) edge of the surface, and lies no more than 10 cm from it. The tipping is limited to an angle at most plus or minus 15 degrees in relation to the central position. The maximum angle can be adjustable, and there may be limiters which limit the tipping. These limiters are elastic for damped limitation of the maximum tipping movement.</p> |
