Multifunctional seat

  • 03-Apr-2012 03:01 EDT

Merging electronic and ergonomic components, Grammer offers integrated solutions for driver workplaces. The company’s Innovation Star is a Maximo evolution active premium seat for large tractors. The seat features electronically controlled active suspension for retrofitting and multifunctional armrests. A required 12-V power supply need not be connected to the hydraulic system. An air suspension with active electronic adjustment of the curve used to control it can decrease vibration and reduce the intensity of jolts by 40% compared to conventional pneumatic suspensions. Sensors capture the position and induced vertical acceleration of the upper section, and then a controller applies a defined algorithm to operate an electropneumatic valve. The curve controlling the suspension is changed by varying the flow rate, and an active seat climate system ensures a consistent temperature.
