ABSTRACT:
A seat supporting assembly for use in vehicles and the like for resiliently supporting a seat. The seat supporting assembly includes a base which is to be secured to the vehicle and a seat support positioned vertically above the base and resiliently supported by a coil spring. The seat supporting assembly also includes a ride height adjustment assembly and an adjustable vertical movement stop assembly for limiting the upward vertical movement of the seat support. The ride height adjustment assembly includes a plurality of pivotable links extending between the coil spring and the seat support. The links are connected by means of a threaded shaft and are relatively movable at their upper ends to cause vertical extension of the height adjustment assembly thereby causing variation in the height of the seat support. The threaded shaft projects forwardly from under the seat support and is readily accessible to the vehicle operator. The vertical movement stop assembly includes adjustable means for limiting the upward movement of the seat support with respect to the base. The stop assembly is adjustable to permit various ranges of vertical movement of the seat support to be consistent with the position of the seat support as set by the ride height adjustment assembly. The seat supporting assembly also includes means for indicating the relative positions of the ride height adjustment means and the vertical movement stop assembly so that their relative positions can be properly aligned.
