ABSTRACT:
The member is intended to connect the zigzag tensioning wires mounted parallel to each other in a frame reinforcing a seat cushion. It comprises a flat bar (12) provided at regular intervals with gripping lugs (14) pressing against the bar a straight portion of the wire which is parallel to this bar. Side walls (16, 17) of the bar comprise spaced notches for receiving and fixing portions (4b) of the wire substantially perpendicular to the bar. Since the bar has a lug gripping each wire, the latter are kept at a precise distance from each other and the cushion is locally tensioned.
