Backpack/seat combination

Abstract

An improved backpack/seat combination includes a main container having a front wall, rear wall, side walls, a base wall, an interior volume and a top lid enclosing the interior volume, the main container constructed of a rigid material and at least one backpack strap mounted on the main container. A seat back/lumbar support structure includes a seat back/lumbar support pad mounted on a seat back support bar, the seat back support bar at least one of adjustably, pivotably and movably mounted on the main container. Finally, the seat back/lumbar support pad is movable between a lower, rearwardly-facing lumbar support position positioned adjacent the rear wall of the container box and towards the base wall and an upper, forwardly-facing seat back position positioned above the top lid of the container box by at least one of adjusting, pivoting and moving the seat back support bar.

1 . A backpack/seat combination comprising:
 a main container having a front wall, rear wall, side walls, a base wall, an interior volume and a top lid enclosing said interior volume, said main container constructed of a rigid material;   at least one backpack strap mounted on said main container;   a seat back/lumbar support structure including a seat back/lumbar support pad mounted on a seat back support bar, said seat back support bar at least one of adjustably, pivotably and movably mounted on said main container; and   said seat back/lumbar support pad movable between a lower, rearwardly-facing lumbar support position positioned adjacent said rear wall of said container box and towards said base wall and an upper, forwardly-facing seat back position positioned above said top lid of said container box by at least one of adjusting, pivoting and moving said seat back support bar.   
   
   
       2 . The backpack/seat combination of  claim 1  further comprising;
 a pair of upright tubes mounted on said rear wall of said main container;   a pair of seat back mounting bars each slidably mounted within one of said pair of upright tubes;   a generally U-shaped seat back support bar having a center base section and opposite top ends, said seat back support bar pivotably mounted on and extending between said seat back mounting bars intermediate said center base section and said top ends generally adjacent the upper ends of said seat back mounting bars to permit said seat back support bar to pivot relative to the seat back mounting bars; and   said seat back/lumbar support pad movable between a lower, rearwardly-facing lumbar support position positioned adjacent said rear wall of said container box and towards said base wall and an upper, forwardly-facing seat back position positioned above said top lid of said container box by said seat back mounting bars being lifted within said upright tubes, said seat back support bar being pivoted to rotate said seat back/lumbar support pad from said lower position to said upper position, said seat back mounting bars being lowered within said upright tubes such that said opposite top ends of said seat back support bar are positioned below said top lid and said seat back/lumbar support pad is generally prevented from rearward rotation due to engagement of said opposite top ends with said rear wall of said container box.   
   
   
       3 . The backpack/seat combination of  claim 1  further comprising a backpack pad mounted on said rear wall of said main container which extends rearwards and outwards therefrom. 
   
   
       4 . The backpack/seat combination of  claim 1  wherein said top lid and said main container form a generally fluid-tight seal whereby incursion of external contaminants into said main container is generally prevented. 
   
   
       5 . The backpack/seat combination of  claim 1  further comprising at least one external pocket mounted on one of said front and side walls of said main container. 
   
   
       6 . The backpack/seat combination of  claim 1  further comprising two adjustable-length backpack straps, each mounted on said rear wall of said main container. 
   
   
       7 . A backpack/seat combination comprising:
 a main container having a front wall, rear wall, side walls, a base wall, an interior volume and a top lid enclosing said interior volume, said main container constructed of a rigid material;   at least one backpack strap mounted on said main container;   a seat back/lumbar support structure including;
 a pair of upright tubes mounted on said rear wall of said main container; 
 a pair of seat back mounting bars each slidably mounted within one of said pair of upright tubes; 
 a seat back support bar pivotably mounted on and extending between said seat back mounting bars generally adjacent the upper ends of said seat back mounting bars to permit said seat back support bar to pivot relative to the seat back mounting bars; 
 a seat back/lumbar support pad mounted on said seat back support bar; 
   said seat back/lumbar support pad movable between a lower, rearwardly-facing lumbar support position positioned adjacent said rear wall of said container box and towards said base wall and an upper, forwardly-facing seat back position positioned above said top lid of said container box by said seat back mounting bars being lifted within said upright tubes, said seat back support bar being pivoted to rotate said seat back/lumbar support pad from said lower position to said upper position and said seat back mounting bars being lowered within said upright tubes whereby said seat back/lumbar support pad is generally prevented from rearward rotation due to engagement of said seat back support bar with said rear wall of said container box.   
   
   
       8 . The backpack/seat combination of  claim 7  further comprising a backpack pad mounted on said rear wall of said main container which extends rearwards and outwards therefrom. 
   
   
       9 . A backpack/seat combination comprising:
 a main container having a front wall, rear wall, side walls, a base wall, an interior volume and a top lid enclosing said interior volume, said main container constructed of a rigid material;   a backpack pad mounted on said rear wall of said main container which extends rearwards and outwards therefrom;   at least one backpack strap mounted on said main container;   a seat back/lumbar support structure including;
 a pair of upright tubes mounted on said rear wall of said main container on opposite sides of said backpack pad; 
 a pair of seat back mounting bars each slidably mounted within one of said pair of upright tubes; 
 a generally U-shaped seat back support bar having a center base section and opposite top ends, said seat back support bar pivotably mounted on and extending between said seat back mounting bars intermediate said center base section and said top ends generally adjacent the upper ends of said seat back mounting bars to permit said seat back support bar to pivot relative to the seat back mounting bars; 
 a seat back/lumbar support pad mounted on said center base section of said seat back support bar; 
   said seat back/lumbar support pad movable between a lower, rearwardly-facing lumbar support position positioned adjacent said rear wall of said container box and towards said base wall and an upper, forwardly-facing seat back position positioned above said top lid of said container box by said seat back mounting bars being lifted within said upright tubes, said seat back support bar being pivoted to rotate said seat back/lumbar support pad from said lower position to said upper position, said seat back mounting bars being lowered within said upright tubes such that said opposite top ends of said seat back support bar are positioned below said top lid and said seat back/lumbar support pad is generally prevented from rearward rotation due to engagement of said opposite top ends with said rear wall of said container box.
