<p>The seat shell is supported on two pendant levers (9, 10) pivotted about two axes on an upper support bar (11). The levers are further fitted with spring frams (19) to hold them on a central position when displaced laterally. The upper bar is at the top of a vertical support with vertical damping. A damper (23) braces the frame laterally. The seat is thus sprung in all directions and can be used on construction vehicles, especially on rough ground. The spring pressures can be adjusted to accommodate different weights of drivers.</p> |
