6.2 Seat
6.2.1 Seat width (SW)
Available seat widths: SW 320 to 500 in 20 mm steps.
Changing the seat width is very complicated and requires the replacement of numerous parts.
6.2.2 Seat depth (SD)
Available seat depths: SD 350 to 525 in 25 mm steps.
Changing the seat depth requires the replacement of the complete seat module including the seat cover and the seat rail
and potentially also the seat cushion.
6.2.3 Seat angle (SA)
The seat angle is determined by the difference between the rear seat-to-floor height (RSTF) and the front seat-to-floor
height (FSTF).
6.2.4 Front seat-to-floor height (FSTF)
Adjusting the front seat-to-floor height (FSTF)
Reposition or replace the brackets at the front frame to adjust the front seat-to-floor height.
