The back connecting bar has first and opposite ends that are aligned with one another in the shape of an “L.” The first end of the connecting bar is fixedly connected within and extends outwardly from the chair back. The opposite end of the connecting bar is detachably connected to the bottom of the chair seat by threaded fasteners which extend through holes formed in the opposite end for removable receipt by the seat.

1 . A combination comprising:
 a chair back;   a chair seat; and   a back connecting bar by which said chair back is attached to said chair seat so as to stand upwardly therefrom, said back connecting bar extending from said chair back and adapted to be detachably connected to said chair seat without the use of tools.   
     
     
         2 . The combination recited in  claim 1 , wherein said back connecting bar has first and opposite ends, said first end being fixedly connected inside said chair back, and said opposite end adapted to be detachably connected to said chair seat without the use of tools. 
     
     
         3 . The combination recited in  claim 2 , wherein the first and opposite ends of said back connecting bar are aligned with one another in the shape of an “L.” 
     
     
         4 . The combination recited in  claim 2 , wherein said chair back has an external surface, the first end of said back connecting bar extending outwardly from said chair back through said external surface via a slot formed therein. 
     
     
         5 . The combination recited in  claim 2 , wherein the opposite end of said back connecting bar is detachably connected to said chair back at the bottom thereof. 
     
     
         6 . The combination recited in  claim 2 , further comprising at last one fastener extending through the opposite end of said back connecting bar for removable receipt by said chair seat by which said opposite end is detachably connected to said chair seat. 
     
     
         7 . The combination recited in  claim 6 , wherein the opposite end of said back connecting bar has at least one hole formed therein, said one fastener extending through said opposite end at said one hole thereof. 
     
     
         8 . The combination recited in  claim 7 , wherein said one fastener has a screw threaded first end to extend through the one hole formed in the opposite end of said back connecting bar for said removable receipt by said chair seat. 
     
     
         9 . The combination recited in  claim 8 , wherein said one fastener has a knob located at the opposite end thereof, a rotational force applied to said knob in a first direction causing the screw threaded first end of said fastener to move into said removable receipt by said chair seat. 
     
     
         10 . The combination recited in  claim 9 , wherein a rotational force applied in an opposite direction to the knob of said one fastener causing the screw threaded first end of said fastener to move out of said removable receipt by said chair seat, whereby the opposite end of said back connecting bar is disconnected from said chair seat and said chair back is detached from said chair seat.
