Abstract

A convertible sitting/reclining furniture article comprises a main frame and a seat element which is supported at a predetermined elevation above ground. A bed frame can be pulled out of and pushed into the main frame in a drawer-like manner and includes a front side, a rear side and two lateral sides. An extension element is mounted on the bed frame for displacement between a retracted position and an extended position in which the extension element is disposed at the predetermined elevation to form an extension of the seat element by a five-bar kinematic linkage at each of the lateral sides of the bed frame. Each of the kinematic linkages includes a steering lever pivotally mounted at a first region of the extension element and at a first portion of the bed frame, and two steering links more remote from the front side of the bed frame than the steering lever and adjacent to the steering lever. The steering links are articulately connected to one another at a connection region and one of them is pivotally connected to a second region of the extension element while the other is pivotally connected to a second portion of the bed frame which is spaced from said first portion by a distance exceeding the distance between the first and second regions of the extension element. The steering links assume a straight-line orientation with respect to one another in the extended position of the extension element to block the connection region against pivoting in at least one of its pivoting directions.
