poly-Dynamic Air-Suspension™ System:

• It combines the isolator function (fore & aft suspension) with the air-suspension system (vertical suspension): (Knoedler original)

Advantages are:

• Improved performance as both directions of the suspension are coherently integrated and therefore work together.
• Increased comfort:
  • As the ICP's (Inter Connecting Points) of the lower 2 Seat-Belt-points move with both the suspension and the isolation movement during normal operation. Therefore there is no relative movement of the seat belt in regards to the body. This drastically improves the seat belt wearing experience and gives the opportunity for full use of the seat belt system.
  • This system helps eliminate the "belt tightening effect" that is typical with "detached / separate" isolator mechanisms.
