||Adding seat-belts to your cockpit chair can enhance the
flight simulation experience. The fact that you are strapped-in, make the
motion platform movements more pronounced. You can further enhance some in
flight feelings by manipulating the tightness of the belt in certain
During deceleration, especially during braking on the runway, the forward forces on your body can be considerable, and you would feel yourself being pushed into your seatbelts. Since my platform has limited tilt, this feeling is not very pronounced. Therefore I added a seat-belt system that will tighten the belt when the platform tilts forward.
The system is very simple: Strings with springs are attached to the seat-belt tightening points. The other ends are fixed to the floor. When the rear of the platform lifts-up, the strings will stretch the springs, and the belt is tightened. This is shown in the drawing below.
This video shows the system in action. I did some adjustments to make the strings start to tighten the belt when the platform forward tilt is about 40% of max. Tightening force at max is about 5 ~ 7kg per point.
