Chair with lateral frame parts connected by transverse rods supporting seat and backrest
First Claim
1. A chair comprising:
- two lateral frame parts, each one of said frame parts comprised of a single, continuous member of an elastically yielding material;
transverse rods connected between said lateral frame parts;
a seat connected to at least one of said transverse rods; and
a backrest connected to at least one of said transverse rods; and
wherein each one of said single members of said lateral frame parts has an upper rearward end, a lower rearward end, and a floor-contacting portion, wherein each one of said single members is curved continuously at a first radius of curvature from said upper rearward end forward and downward, then rearward and downward to said floor-contacting portion, from said floor-contacting portion upward and rearward, and then with an arc of a second radius of curvature, substantially smaller than said first radius of curvature, downward and rearward to said lower rearward end, wherein an end portion of said single member, positioned between said lower rearward end and said arc, extends straight downward and rearward at a slant.

Abstract
A chair has two lateral frame parts, each one in the form of a single, continuous member of an elastically yielding material. Transverse rods are connected between the lateral frame parts. A seat is connected to at least one of the transverse rods and a back rest is connected to at least one of the transverse rods. The single member of the lateral frame parts is preferably made of spring steel. Connecting elements that are slipped onto the lateral frame parts are used for connecting the transverse rods to the lateral frame parts. The connecting parts can be balls having throughbores for receiving the lateral frame parts and threaded holes, extending substantially perpendicularly to the throughbores, for receiving the transverse rods.
