Abstract
A spring base for upholstered seating, particularly automotive seats having upwardly and outwardly inclined "wings" or bolsters at the sides thereof, consisting of a pair of spaced apart side bolster wires each adapted to be supported by spaced helical springs attached thereto and extending outwardly therefrom for connection at their outer ends to a fixed frame, and a series of relatively closely spaced spring cross wires extending between the bolster wires and connected thereto, certain of the cross wires being of relatively small gauge and extending only between the bolster wires, and certain of the cross wires being relatively heavy gauge and extending beyond the bolster wires and being angled upwardly and outwardly to provide spring support for the bolsters, all with the purpose of providing the necessary spring strength in the various areas of the seat, as well as the necessary closeness of the wires to provide adequate support for the helical springs and adequate support for the cushioning material applied thereover, with a minimum of wire weight, and hence the greatest possible economy of cost.
