DEFINITION

Classification: 267/80

(under the class definition) Device which includes an outline of rigid elongated mounting elements spaced from each other, and either (1) a resilient load supporting surface located on or between and connected to said elements, or (2) a rigid load supporting surface located on or between and connected to said elements by resilient means.

(1) Note. Although the load supporting surface may be capable of receiving the ultimate load directly, a more common arrangement would include padding and a covering material between the load and the supporting surface.

(2) Note. The devices classified in this and the indented subclasses are mainly the spring subcombinations of chair and seat cushions.
