Benefits of technology

The present invention is a seat for a work vehicle which can accommodate a person's upper body at a comfortable position. The seat includes a seat bracket, bottom frame, top frame, and a setting tool for adjusting the top frame to different positions. The seat also has an upper seat back and a lower seat back, which can be fixed at different positions to accommodate people of different statures. The vertical position adjustment of the upper seat back is achieved by a tubular member and a slide rod, which can be fixed with a fixing pin or frictional force. The technical effect of this invention is that it provides a more comfortable and adjustable seat for work vehicles.

Problems solved by technology

For this reason, it is difficult for a person of a high sitting height or a low sitting height to have his / her upper body (in particular, the area downwardly of the shoulder) accommodated by this seat back at a comfortable position.
Similarly, with the seat according to the U.S. Pat. No. 10,023,083 too, as the position of the seat back is immovable relative to the seat cushion, it is difficult for an upper body of a person seated in the seat cushion to be accommodated at an appropriate position.

Embodiment Construction

[0023]In the following embodiment, as one example of a work vehicle on which the inventive seat is to be mounted, a zero-turn mower is used. Incidentally, in this detailed description, unless indicated explicitly otherwise, “front” means the front side with respect to the machine body front / rear direction (traveling direction), and “rear” means the rear side with respect to the machine body front / rear direction (traveling direction). Also, the left / right direction or lateral direction means the machine body transverse direction (machine body width direction) perpendicular to the machine body front / rear direction. And, “upper” or “lower” refers to the positional relation with respect to the perpendicular direction (vertical direction) of the machine body, representing the relation with respect to the ground clearance.

[0024]As shown in FIG. 1 and FIG. 2, this zero-turn mower includes a vehicle body frame 10 which is supported on the ground surface via a front wheel unit 2 configured a...

Abstract

A seat for a work vehicle includes a bottom frame fixed to a seat bracket supported to a vehicle body frame, a top frame supported to the bottom frame to be vertically slidable relative thereto, a setting tool for setting the top fame to the bottom fame at a plurality of vertically adjustable position, a seat cushion attached to the bottom frame and a seat back. The seat back consists of an upper seat back attached to the top frame and a lower seat back attached to the bottom frame.

Description

TECHNICAL FIELD[0001]The present invention relates to a seat to be mounted on a work vehicle and consisting of a seat cushion and a seat back.BACKGROUND ART[0002]U.S. Pat. No. 8,561,748 discloses a seat mounted on a zero-turn mower (an off-road vehicle). This seat includes a bottom frame, a back frame, a seat cushion attached to the bottom frame, and a seat back attached to the back frame. The bottom frame is displaceable via a suspension and an adjustment mechanism is provided for adjusting this displacement (movement) of the bottom frame. With this, a movement of the bottom frame, consequentially, a movement of the seat cushion, is adjustable by the adjustment mechanism.[0003]Similarly, in a seat assembly disclosed by U.S. Pat. No. 10,023,083, a seat consisting of a seat cushion and a seat back formed integral with each other is fixed to a seat plate which is pivotable in the front / rear direction about a horizontal axis. The seat plate is supported to a seat base via a suspension ...
