     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 8 thereof, a new and improved ATV backrest embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the ATV backrest 10 of the instant invention essentially comprises a mounting tube and all terrain vehicle top plate 12 of an all terrain vehicle 11 in adjacency to a seat member 12a (see FIG. 1). Respective first and second mounting tubes 13 and 14 are arranged in a parallel coextensive relationship and are mounted to the top plate 12, each arranged to orthogonally receive respective first and second lock pins 15 and 16 (see FIG. 3 for example). First and second support tubes 17 and 18 arranged in a parallel coextensive relationship and oriented orthogonally relative to the first and second mounting tubes 13 and 14 are arranged such that the first and second support tubes 17 and 18 include a plurality of cross tubes 19 to integrally orient the first and second tubes 17 and 18 in the parallel relationship, in a manner as indicated in FIGS. 1 and 3 for examples. A seat support bracket 20, as indicated of a generally U-shaped configuration, is mounted fixedly at an angle medially of the first support tube 17, with a plurality of brace tubes 21 provided, wherein each of the brace tubes 21 extend fixedly from the support bracket 20 to the second support tube 18. A cross tube 42 is indicated for providing enhanced stability in the mounting of a cushion member 22 to the seat support bracket 20 on an opposed side relative to the brace tubes 21. 
     First and second L-shaped rods are provided, wherein the first L-shaped rod includes first L-shaped rod first and second legs 23 and 24 oriented orthogonally relative to one another, with the second L-shaped rod having second L-shaped rod first and second legs 25 and 26. The first and second L-shaped rod second legs 24 and 26 are arranged for reception within the first support tube 17. The first and second L-shaped rods first legs 23 and 25 respectively are arranged for sliding reception within the first and second mounting tubes 13 and 14, with first and second apertures 27 and 28 directed through the respective first and second rod first legs 23 and 25 arranged to receive the respective first and second lock pins 15 and 16 of the first and second mounting tubes 13 and 14 respectively to permit securement of the L-shaped rods and the associated cushion member relative to the ATV top plate 12. Second support tube apertures 29 (see FIG. 4) are directed into the second support tube 18, wherein first and second L-shaped rod third legs 30 and 31 are mounted parallel at an equal distance relative to the respective first and second L-shaped rod second legs 24 and 26 spaced an equal distance therefrom relative to an equal spacing indicated by the orientation of the first and second support tubes 17 and 18 relative to one another to permit reception of the respective first and second L-shaped rod third legs 30 and 31 into opposed ends of the second support tube 18. Third and fourth leg apertures 32 and 34 are directed into the respective first and second L-shaped rod third legs 30 and 31, wherein third and fourth leg pins 33 and 35 are arranged for reception through the respective third and fourth leg apertures 32 and 34 into an individual one of the second support tube apertures 29 to secure the L-shaped rods relative to the support tubes 17 and 18. In this manner, disassembly of the organization for storage and transport is availed to one employing the invention. 
     The FIGS. 5 and 6 indicate the use of a modified cushion member 22a in lieu of the cushion member 22. To this end, the seat support bracket 20 includes a plurality of support bracket cross tubes 42 that are parallel relative to one another and to the underlying first support tube 17. The modified cushion member 22a includes a continuous outer perimeter 36 having a central opening 37 (see FIG. 6), wherein a central opening cushion 38 is arranged for reciprocation through the central opening 37. A central cushion mounting plate 40 is secured within the central opening cushion 38, with a plurality of mounting plate adjuster rods 41 orthogonally mounted fixedly to the mounting plate 41, wherein spacer rings 43 are arranged for reception in adjacency to the mounting plate about the individual adjuster rods 41, such that the adjuster rods subsequently are directed each through an individual one of a support bracket cross tube 42 of a plurality of such tubes that are parallel relative to one another. Upon projection of the adjuster rods 41 through the cross tubes 42, fastener members 44 are secured about the adjuster rods 41. In this manner, dependent upon the number and the thickness of the spacer rings 43, the orientation of the opening cushion 38 is arranged for adjusted projection relative to the continuous perimeter 36, as desired, for additional lumbar support. 
     The FIGS. 7 and 8 indicates the displacement of the cushion member 22a to a stored orientation relative to the bracket assembly such that a slide tube 45 is mounted slidably about each of the brace tubes 21 such that each slide tube 45 is secured to a free end of a generally U-shaped slide tube support rod 46, wherein the slide tube support rod 46 is arranged for reception within a resilient C-shaped first clamp 47 at a first end of the continuous perimeter 36, wherein a second end of the perimeter 36 includes a resilient C-shaped second clamp 48 arranged for mounting upon the seat support bracket 20.
