초록

The seating spring assembly includes a series of elongate sinuous spring wires with each of the wires touching each of the adjacent spring wires at frequent intervals along their length. Frangible welds, in the form of spot welding, are provided at spaced apart touching locations along the lengths of the wires to temporarily secure the adjacent spring wires together. A sleevelike plastic coating surrounds the wires and the frangible welds are broken when the seat is occupied by a person so that the plastic coating then constitutes the sole element holdin...
