Air-spring driver’s seats give the operator’s workplace a more ergonomic and comfortable design, thereby reducing fatigue and work-related health risks.
As a rule so-called sleeve type air springs are used in commercial vehicle driver’s seats. Thanks to their compact construction they can easily be integrated into the seat frame. The force is transmitted from the seat backing to the air spring via a control-sleeve lever or a so-called scissors construction. At working pressure levels between 3 and 7 bar max. this provides not only for a comfortable spring characteristic but also for an infinitely adjustable seat height. The internal pressure is automatically adapted to the specific weight of the operator by means of a height-control valve.
Because of their ergonomic advantages, air-spring driver’s seats are more or less a standard feature these days, not only in buses and heavy long-distance trucks but increasingly in agricultural and construction machines such as, for example, tractors and wheel loaders as well.
