Claim:
1. A bed assembly comprising a foldable bed frame pivotably connected to a sofa back support via a linkage, such that the sofa back support is configured to automatically pivot via the linkage from a substantially vertical first position to the angularly oriented second position when the bed frame transitions from an extended position to a stored position, and the angularly oriented second position to the substantially vertical first position when the bed assembly transitions from the stored position to the extended position, said linkage comprising, a first slotted link defining a slot, said first slotted link affixed to said sofa back support; an adjustment link defining at least two portions, said first adjustment link portion slideably attached to said first slotted link, said second adjustment link portion in pivotable communication with a linking link; a first link attached to said bed frame and a joining link, the joining link rotatably connected to both a coupling link and a first planar link, said coupling link attached to a base member mounted to the sofa; whereby said first adjustment link portion defines a substantially vertical orientation in a first position when said bed frame is in an extended position, whereby said first adjustment link portion travels a linear distance within said slot to define a substantially horizontal orientation in a second position relative to said first position when said bed frame is in a stored position; and whereby the attachment, orientation, and rotation of said first slotted link, said adjustment link, said first planar link, and said joining link result in a sofa back support that is configured to pivot automatically from the substantially vertical first position to the angularly oriented second position when the bed frame transitions from an extended position to a stored position, and the angularly oriented second position to the substantially vertical first position when the bed assembly transitions from the stored position to the extended position.
