<p>The present invention is a sofa bed recliner (10) that can be simply opened into a bed or closed to form a sofa. The recliner includes a mechanism which allows the sofa bed recliner to be opened or closed while being in close proximity with a wall. The recliner includes a main frame (12), a back frame (14), and a seat frame (16). The mechanism provides for the positive locking of the back frame element (14) to the seat frame element (16) both in the opened and closed position to assure a rigid structure in both positions. The mechanism includes a link arm (42) pivotally attached to the back frame (14) and the main frame (12), a guide groove (50) formed in the main frame (12) and a groove follower (52) attached to the back frame (14), and a hinge and stop structure pivotally attaching the seat and back frames together. The structure includes a longitudinal notch (56) and a normal notch (58) attached to an end (54) of the back frame (14) which engages a pin (66) attached to an end (60) of the seat frame (16). A slot (62) is formed in the back frame end (54) and engages a pin (64) attached to the seat frame end (60).</p> |
