Claims

[Scope of utility model registration request]

It is connected to the side cord 4 by a partially wound portion 3B on the side cord 4 and at an angle crosses at least one of said side cords 4 for interlocking and fastening with the other side steel wire 5. A sheet structure comprising a steel wire lattice mat 2 consisting of a plurality of horizontal spring steel wires 3 extending between two side cords 4 which are wound on a side cord 4 before being stretched; , an intermediate portion 3 of the horizontal spring steel wire 3 extending between the side cords 4 and, on the other hand, an end portion 3A of the horizontal spring steel wire 3 extending between the outer member, i.e., each side cord 4 and the end portion, i.e., the side steel wire 5. form bent portions of the lattice mat that can be bent with respect to each other, and the outer ends 3A of the lattice mat extend away from the center of the lattice mat in the direction toward the seat frame 1, and connected directly to the end of 1,
and that at least a large part of said lattice mat is covered with a synthetic foam cushioning material 7, and further that the bends of the lattice mat 2 define a recess between the seat frame 1 and the main body of the foam cushioning material 7. Characteristic sheet structure.
