DEFINITION

Classification: 297/46

(under subclass 16.1) Device wherein the back and legs are movably joined to each other or to other chair components so that the back and the several legs each fold relative to the other and at the same time.

(1) Note. The chairs in this and the indented subclasses may include an integral back frame and leg pair as classified below in subclasses 55+ and 59+, but are distinguished from that art in that the chairs in the former subclasses have a back which moves relative to the back frame in its collapsing movement.

SEE OR SEARCH THIS CLASS, SUBCLASS:

55+, for an integral back and front legs interconnected with the back legs to fold concurrently, and see (1) Note above.

59+, for an integral back and rear legs interconnected with the front legs to fold concurrently, and see (1) Note above.
