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. |
