<p>A stop pawl engages in a toothed sector. Positioning is assured by a holding lever and spring acting in conjunction with an adjusting button in an oblong hole of a coupling rod. The position of a drive is determined by the control button against the end of an oblong hole of an adjustment lever. To adjust the back inclination a handle is turned clockwise, thus the drive arms move in conjunction with the adjustment lever. The adjusting buttons, via the coupling rods, connect with the holding lever. The pawls hold the position. Once this has been found, the handle is released.</p> |
