发明名称 Hinge for convertible sofa
摘要 The present invention is for a sofa bed recliner that can be simply opened into a bed or closed to form a sofa. The mechanism allows the sofa to be opened or closed while being in close proximity with a wall. The mechanism also provides for the positive locking of the back frame element to the seat frame element both in the closed and open position to assure a rigid structure in both positions.
