Abstract:
A sofa bed traversable between a sofa and bed configurations is disclosed herein. It has a folding mechanism having first and second pairs of link members rotatably attached to a backrest and support members on left and right sides of the back rest. Via the first and second link members, the back rest is transitionable between the sofa configuration and the bed configuration. A seat base is movable up and down at an angle via a sliding mechanism.

Claim (Index 1):
A convertible sofa bed with a folding mechanism capable of traversing the sofa bed between a sofa configuration and a bed configuration, the sofa bed comprising:\n a left support member and a right support member, both configured to rest on an underlying surface; a backrest having a left end and a right end, the backrest being horizontally disposed between the left support member and the right support member, wherein the left end is attached to the left support member and the right end is attached to the right support member and wherein the backrest is configured to pivot up when the sofa bed is traversed to the sofa configuration and pivot down when the sofa bed is traversed to the bed configuration, the backrest having a front side and a rear side, the rear side defining a bed frame, the bed frame being engageable with a mattress; a seat base having a left end and a right end attached to the backrest; and the folding mechanism comprising:\n a left first link member rotatably attached to the left backrest end and the left support member, and a right first link member rotatably attached to the right backrest end and the right support member, wherein the left and right first link members push upward on the backrest when the sofa bed is in the bed configuration; \n a left second link member rotatably attached to the left backrest end and the left support member and a right second link member rotatably attached to the right backrest end and the right support member, wherein the left and right second link members push downward on the backrest when the sofa bed is in the bed configuration; \n wherein the rotational moment as a result of the weight of the backrest, along with the weight of any person resting on it, and the weight of the seat base, is counteracted by the moment resulting from the reaction force couple generated by the left and right, first and second, link members, and vectors of the reaction forces generated by the first link members, are vertical and parallel to vectors of the reaction forces of the left and right second link members to lock the backrest at the bed configuration.
