3.1 Seating system description
•Seat height (B): this is the height of seat measured starting from the chassis (line a). When
seat angle is different from zero, you should have two different values for front and back
seat height.
Figure 1
•Seat angle (C): this is the angle between the seat and the chassis (line a). Seat angle is
positive when the seat is tilted rearward, zero when the seat is horizontal and negative when
the seat is tilted forward.
•Absolute backrest angle (D): this is the angle between the backrest and the seat.
•Backrest angle (E): this is the angle between the backrest and the chassis of the wheelchair
(line a). Only when seat angle is zero, absolute backrest angle is equal to backrest angle.
Figure 2
•Absolute legrest angle (F): this is the angle between the legrest and line perpendicular to
the seat (g).
•Legrest angle (H): this is the angle between the legrest and the line perpendicular to the
chassis of the wheelchair (line m). Only when seat angle is zero, absolute legrest angle is
equal to legrest angle.
