A vehicle seat has a seat bottom and a seat back, which pivots at a rear side of the seat bottom. Within the rearward-facing surface of the seat back, a seat back tray is housed. When in a front passenger seat that is folded forward, the seat back tray is easily assessable by a vehicle driver. To adjust the tray horizontally, a pivotable tray top pivots relative to and above a non-pivoting tray top. A track within the tray provides a guide for movement of the pivotable tray top. A scissor lift coupled to an adjustment mechanism including either a hand crank or electric motor, may raise and lower the tray from a retracted position to an extended position, and be fixed at any intermediary position. The tray may be equipped to be lifted to any intermediary position without a hand crank or electric motor in a low-cost, yet effective scissor mechanism.

What is claimed is: 1. A vehicle seat comprising: a seat bottom; a seat back that pivots at a rear of the seat bottom; a seat back tray located in a rearward facing surface of the seat back, the seat back tray including a non-pivotable tray top and a pivotable tray top, whereby the pivotable tray t
What is claimed is: 1. A vehicle seat comprising: a seat bottom; a seat back that pivots at a rear of the seat bottom; a seat back tray located in a rearward facing surface of the seat back, the seat back tray including a non-pivotable tray top and a pivotable tray top, whereby the pivotable tray top forms a table top when the seat back is pivoted downwardly to rest on top of the seat bottom; a pivot pin rotatably coupled to the non-pivotable and the pivotable tray tops; a track, the track providing a guide for pivotable horizontal movement of the pivotable tray top relative to the non-pivotable tray top, the track including an upper slide groove positioned in the pivotable tray top and a corresponding lower slide groove positioned in the non-pivotable tray top; a slide pin arranged to be positioned in the track and slidably couple the pivotable tray top to the non-pivotable tray top, the slide pin including a top head, a bottom head, and an intermediate region connecting the top and bottom heads, the top and bottom heads having a larger diameter than the intermediate region, the top head arranged to be positioned in the upper slide groove and the bottom head arranged to be positioned in the lower slide groove so as to couple the pivotable tray top to the non-pivotable tray top while allowing the pivotable tray top to horizontally pivot about the pivot pin relative to the non-pivotable tray top; and a scissor lift, wherein the scissor lift permits vertical adjustment of the seat back tray relative to the seat back. 2. The vehicle seat of claim 1, further comprising: an electric motor to drive the scissor lift for raising and lowering the table top from a retracted position to an extended position, and any fixed intermediary position. 3. The vehicle seat of claim 1, wherein the scissor lift further comprises a manual adjustment mechanism for raising and lowering the table top from a retracted position to an extended position, and any fixed intermediary position. 4. The vehicle seat of claim 3, further comprising: a hand crank attached to the manual adjustment mechanism for adjusting the scissor lift. 5. The vehicle seat of claim 4, wherein the hand crank adjustment mechanism further comprises a ratcheting mechanism coupled to the hand crank for facilitating cranking of the hand crank adjustment mechanism in either a clockwise or counterclockwise direction. 6. A vehicle seat comprising: a seat bottom; a seat back that pivots at a rear of the seat bottom; a seat back tray located in a rearward facing surface of the seat back, the seat back tray including a non-pivotable tray too and a pivotable tray top, whereby the pivotable tray top forms a table top when the seat back is pivoted downwardly to rest on top of the seat bottom and the pivotable tray too is in a non-pivoted position; a pivot pin rotatably coupled to the non-pivotable and the pivotable tray tops; a track, the track providing a guide for pivotable horizontal movement of the pivotable tray top relative to the non-pivotable tray top, the track including an upper slide groove positioned in the pivotable tray top and a corresponding lower slide groove positioned in the non-pivotable tray top; a slide in arranged to be positioned in the track and slidably couple the pivotable tray top to the non-pivotabie tray top, the slide pin including a top head, a bottom head and an intermediate region connecting the top and bottom heads, the top and bottom heads having a larger diameter than the intermediate region, the top head arranged to be positioned in the upper slide groove and the bottom head arranged to be positioned in the lower slide groove so as to couple the pivotable tray to top the non-pivotable tray top while allowing the pivotable tray top to horizontally pivot about the pivot pin relative to the non-pivotable tray top; a recess positioned in a top surface of the pivotable tray top, the recess providing a mechanism for engaging the pivotable tray top so as to pivot the pivotable tray top about the pivot pin; and a scissor lift, wherein the scissor lift permits vertical adjustment of the seat back tray relative to the seat back. 7. The vehicle seat of claim 6, wherein the scissor lift further comprises a manual adjustment mechanism for raising and lowering the table top from a retracted position to an extended position, and any fixed intermediary position. 8. The vehicle seat of claim 7, further comprising: a hand crank attached to the manual adjustment mechanism for adjusting the scissor lift.
