摘要： A vehicle seat comprises a seat pan, a backrest pan, and a pair of connector plates connected to opposite lateral sides of the seat pan. Backrest height adjustment means are connected between the connector plates and the backrest pan to enable the backrest pan to be raised or lowered vertically to desired positions relative to the seat pan wherein it then becomes locked. The backrest height adjustment means comprises: a pair of spaced apart brackets connected to the backrest pan, each having a vertical track and a vertical guide slot, a rotatable control rod extending through the guide slots and having a pair of track sprockets fixed thereon and engaged with the vertical tracks, planocentric gears, including a spur gear fixed to one end of the control rod and a ring gear having internal teeth engaged with the spur gear and fixed to one of the connector plates, an eccentric pin rotatable by a height adjustment knob located outside of the connector plate and having eccentric cylindrical portions, said pin engaged with a circular hole in the spur gear and with a circular hole in the connector plate, whereby knob rotation causes slight harmonic travel (oscillation) and rotation of the spur gear and corresponding rotation of the control rod sprockets along the tracks to cause vertical motion of the backrest pan. A stop member on the spur gear is engageable with stop pins on the ring gear to limit vertical travel. A slideable connection is provided between the other connector plate and the backrest pan.

摘要： 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.

摘要： A seat suspension system for use on a tractor or the like including an air bag means for resiliently supporting a seat and a shock absorber positioned generally vertically but at an incline between the seat and a base frame and functioning to dampen the vertical oscillation of the seat. The shock absorber is pivotably supported to permit variation in its inclination and consequent variation in its damping effect on the relative vertical motion of the seat. A readily accessible adjusting means is provided for changing the relative inclination of the shock absorber and includes a pivotable bellcrank positioned beneath the front portion of the seat and having one lever arm connected to the upper end of the shock absorber. The other lever arm of the bellcrank is accessible to the tractor operator to permit pivotal movement of the bellcrank.

摘要： An adjustable seat suspension system for a vehicle seat for a tractor, earth working equipment, or the like, and in which the seat is resiliently supported by a pressurizable air bag. The seat suspension system provides a manually settable lever by means of which the operator can infinitely vary the height adjustment of the seat for a normal operating position, depending on his size. The seat suspension adjusting mechanism includes a valve for regulating the flow of pressurized air to or from the air bag. The arrangement is such that for any vertical height position selected by the operator, the air controlling mechanism permits the seat to oscillate up and down through a given range of movement, say for example six and one-half inches. In addition to a normal operating oscillation range for any selected height adjustment, the seat suspension control system of the present invention includes a floating pivot point in the control linkage which can shift from its normal operating position to thereby in effect disconnect the control valve and protect it when the seat movement exceeds the limits of the valve spool, which limits are small compared to overall linkage movement requirements.

摘要： A seat supporting assembly for use in vehicles such as tractors or the like wherein the seat is surrounded in relatively close relationship by obstructions such as controls which make it difficult for the vehicle operator to get into and out of the seat. The seat supporting assembly provides means for supporting the vehicle seat such that the seat may be moved rearwardly and then rotated to permit access to or egress from the seat. The assembly also provides means which prevent rotation of the seat unless it has been moved to its furthest rearward position. The seat supporting assembly further includes means to facilitate vertical adjustment of the seat and to secure the seat in its desired vertical position.
