A two frame sofa bed recliner has a seat frame, a back frame, and a pair of arm frames connected to both sides of the recliner. Vertical and horizontal slots are located in each of the arm frames. A first pin connected to a side of an upper portion of the back frame extends into the vertical slot. A second pin connected tog a lower portion of a side of the back frame extends into the horizontal slot. The pins move along the slots to guide the recliner from an upright to a fully reclined position and vice verse. An enlarged corner of the vertical slot securely engages the first pin when the recliner is in the fully reclined position preventing the recliner from jackknifing upward. Counter absorbing elements are fixedly attached to the side of the seat frame absorbs stress or pressure from the slots as the pins move therein and this stress is transferred uniformly along the attached surface of the seat frame.

DETAILED DESCRIPTION The present invention is a simple convertible wooden sofa bed having only a seat frame assembly and back frame assembly.
The frame assemblies are pivotally linked at extending portions which overlap, for the converting and reconverting from sofa bed to recliner.
The seat frame assembly and back frame assembly include wide support beams which serve to elevate them from the floor.
The wide support beam for the back frame assembly elevates it from the floor when the sofa bed recliner is in sofa bed horizontal position or during reconversion.
The support beams overlap and link the back frame assembly and end frame assembly with interactive pivots, pins, a groove and a notch at their overlap portions.
The overlap portions interlock and can interlock to prevent jackknifing when the sofa bed recliner is in horizontal position.
From the recliner position the seat frame assembly and the back frame assembly may be rotated backward so that the back frame assembly rests on the floor for conversion from recliner to sofa bed horizontal position and reconversion back to recliner position.
In a preferred embodiment detachable arm rests are optionally engagable with the sofa bed recliner of the present invention for additional comfort and convenience.
According to the present invention, a sofa bed recliner has a seat frame and back frame.
Each frame has supports.
The supports have portions extending beyond the frame portions.
The extending portions are overlapping and are interactively engaged.
There is a tent on the back frame extending portions, a retainer on the seat frame extending portions, and interactive guides and a second tent between the extending portions of each frame.
The interactive engagement may be brought about by first and second counter absorbing elements on the back frame extending portions and a retainer and guide on the seat frame extending portions or the interactive engagement may include interactive interlocking engagable when the sofa bed recliner is in sofa bed position
