DEFINITION

Classification: 297/105

(under the class definition) Device in which an additional, cumulative body-supporting panel or portion is carried in a nonuse location on or within the bottom of a seating device, and wherein such panel may be moved to a use position so as to be usable in conjunction with the bottom by the occupant of the bottom, and wherein a disarrangement or movement of the bottom is necessary to extend the panel from its nonuse to use position.

(1) Note. Included in this and indented subclasses are superimposed seat cushions wherein one of the seat cushions is rearranged and supported forwardly of the other so as to be used in conjunction with the other.

(2) Note. May of these panels are moved concurrently with an unfolding of the bottom so as to support the occupant in a different manner, i.e., prone rather than sitting, and thus are often labeled "convertible", as to a bed. Seating devices having adjustable parts have been classified according to the type of adjustment rather than on the basis of convertibility.
