| Full qualified VSS Path: | Vehicle.Cabin.Seat.Row1.Pos2.Tilt |
| Description: | Tilting of seat (seating and backrest) relative to vehicle x-axis. 0 = seat bottom is flat, seat bottom and vehicle x-axis are parallel. Positive degrees = seat tilted backwards, seat x-axis tilted upward, seat z-axis is tilted backward. |
| Comment: | In VSS it is assumed that tilting a seat affects both seating (seat bottom) and backrest, i.e. the angle between seating and backrest will not be affected when changing Tilt. |
