Abstract
A seating apparatus includes a torso rest and a semi-seat support or partial support for the seat of the operator of a work vehicle. The torso rest provides support for the torso when the operator leans against the torso rest in a semi standing position and is contoured to act as a backrest in a first operator position and as a front rest in a operator second position. The semi-seat support acts as a partial seat support only in the first operator position. The seating apparatus may also include an additional stowable seat support, armrests, a height adjustment assist mechanism and/or a control console.
Description
- The invention relates to seats for work vehicles. More specifically, it relates to a device and method for comfortably supporting an operator in a multiuse work vehicle, such as a compact loader backhoe, having a first operating position and a second operating position where, for example, the first operating position is a loader operating position and the second operating position is a backhoe operating position.
- Conventional seats for work vehicles are designed for vehicle operation from a fully seated operator position. In multiuse vehicles such as, for example, loader backhoes, in which the operator is required to control the work functions of the vehicle from different angular positions of the seat, the seats have traditionally been designed to rotate to each of the required angles. In many very compact vehicles in which space has been, traditionally, a problem, no seat to provided. In such cases the vehicle operator is required to operate the vehicle from a standing position.
- In multiuse compact vehicles wear work operations may take hours or days to complete, the full standing position is not practical as it is physically tiring. Further, the fully seated position is often not feasible as it requires a rotatable seat in a vehicle in which space is not available. Such a situation requires that the operator have the advantage of comfortably operating the vehicle from at least two angles relative to the vehicle with a space saving seating arrangement.
- The invention provides a seating apparatus that affords the vehicle operator a semi standing position in multiple work positions conducive to operations on multiuse vehicles such as compact loader backhoes. The seating apparatus provides a first portion, or torso rest, and a second portion, or partial seat support integral to the torso rest. The torso rest is a relatively wide portion at a first end of the seating apparatus which is designed to act as a backrest in a first operator position and a front rest in a second operator position. When used as a backrest, the torso rest supports a rear portion of the operator's torso; when used as a front rest, the torso rest supports a front portion of the operator's torso. The first portion narrows and angles toward the operator to form a short support, i.e., a partial or semi-seat support at the second portion of the seating apparatus. The seating apparatus may include height adjustment to accommodate operators of different heights and builds. To transition from one mode of operation to another the operator is merely required to turn his/her body to the required position and use the torso rest as either a backrest or a front rest and use the semi-seat support as a partial seat support, as appropriate.
- Embodiments of the invention will be described in detail, with references to the following figures, wherein:
-
FIG. 1 is an oblique view of a work vehicle including an exemplary in embodiment of the invention; -
FIG. 2 is an oblique view of an exemplary embodiment of the invention in which a sit bar is extended; -
FIG. 3 is an oblique view of the embodiment of the two in which the sit bar is stowed; and -
FIG. 4 is an exploded view of the exemplary embodiment illustrated inFIG. 2 . -
FIG. 1 is an oblique view of a compact work vehicle, i.e., a compact articulated loader backhoe orswing steer 1 incorporating an exemplary embodiment of the invention (see seating apparatus 100). Theswing steer 1 illustrated inFIG. 1 includes aloader portion 10; acab 30; and abackhoe portion 40. Theloader portion 10 includes:front wheels 11 and aloader mechanism 20. Also included in theloader portion 10 are the engine (not shown), hydraulic pump (not shown) and the transmission (not shown). Thebackhoe portion 40 includes:rear wheels 41; abackhoe mechanism 50; andsteering mechanism 60. Thecab 30 includes: controls 31, 32;roll bar 33; and theseating apparatus 100. -
FIG. 2 is an oblique view of theseating apparatus 100 illustrated inFIG. 1 . As shown inFIG. 2 , theseating apparatus 100 of this exemplary embodiment of the invention includes: an integral operator rest 105 including atorso rest 110 and asemi-seat support 120;forearm rests 130; aplastic trim support 140; acontrol console molding 150 havingapertures control levers sit bar assembly 160; and a heightadjustment assist mechanism 170. The heightadjustment assist mechanism 170 of this exemplary embodiment is a conventional hydraulic mechanism and, as such, is not detailed here. In this particular embodiment, height adjustment is ultimately accomplished via relative movements between afemale slide 132, to which the torso rest is attached, and amale slide 133. Thefemale slide 132 slides upon themale slide 133 during height adjustments. - The
torso rest 110 is contoured to provide a comfortable backrest during loader operations, i.e., when the operator is facing theloader portion 10 and a comfortable front rest for the torso during backhoe operations, i.e., when the operator is facing thebackhoe portion 40. Toward the top of and integral to thetorso rest 110 are the arm rests 130. Toward the bottom of the torso rest 110, the operator rest 105 narrows and protrudes toward theloader portion 10 to form thesemi-seat support 120. Thesemi-seat support 120 is shaped and dimensioned to provide partial support for the seat of the operator during loader operations and to provide little to no support and no interference during backhoe operations. - The
torso rest 110 of this exemplary embodiment is rigidly attached to thecontrol console 150 and thefemale slide 132 which includes rigidly attached sitbar support brackets 132 a. Thesit bar 161 of thesit bar assembly 160 is operatively attached to thesupport brackets 132 a as illustrated inFIGS. 2 and 3 and optionally affords additional support for the seat of the operator. As shown inFIGS. 2 and 3 , thesit bar 161 as two positions; a support position as illustrated inFIG. 2 which provides additional support for the seat of the operator, and a stowage position as illustrated inFIG. 3 which avoids interference with the operator during backhoe operations. - Protruding from the
torso rest 110 toward thebackhoe portion 40 is thecontrol console 150 includingapertures female slide 132 and thecontrol console 150 is aplastic trim support 140 which supports and maintains the shape of thetrim 140 a illustrated inFIG. 1 . - During work operations for the illustrated
swing steer 1, the vehicle operator may merely assume a position facing theloader portion 10 or thebackhoe portion 40 and lean against thetorso rest 110, using it (the torso rest 110), respectively, as a backrest or a front rest. During loader operations, thesemi-seat support 120 may partially support the seat of the operator; thesit bar 161 may optionally provide additional support for the seat of the operator in the support position illustrated inFIG. 2 . During backhoe operations, thesit bar 161 is conveniently placed in the stowage position, as illustrated inFIG. 3 , and the arms of the operator are placed on thearm rests 130 to provide comfortable access to the backhoe controls 150 a and reduce potential operator arm fatigue. - Having described the illustrated embodiment, it will become apparent that various modifications can be made without departing from the scope of the invention as defined in the accompanying claims.
