The scissors linkage is supported by an air spring system and shock absorber, the seat bracket assembly is bolted to reduce distortion and a dual diameter roller system provides accuracy, reduces movement, and the seat bracket is connected to the vehicle frame through the scissors link lower pivot anchor by flexible tension members permitting the seat belts to be attached to the seat or seat bracket.
