ABSTRACT:
A dual spring support for particular use in supporting a vehicle or tractor cab or the like, and specifically including two co-axially disposed springs extending intermediate two spaced-apart vehicle members which are to be cushion supported relative to each other. An abutment piece is disposed between two ends of the two springs, and abutment surfaces are disposed at the other two ends of the two springs, all so that the springs are opposing in their forces and increase the force at each end of the stroke. Also a shock absorber is shown incorporated in the assembled support.
