Abstract
A structure intends to arrange the appearance of furniture at a connecting portion between a first member having stiffness and a second member movable relative to the first member and having stiffness without forming the connecting portion in an unnaturally large diameter. More specifically, the present invention provides a structure for connecting members comprising: a first member having stiffness; a second member movable relative to the first member and having stiffness; and a spring member in which an end portion thereof is connected to the first member and other end portion thereof is connected to the second member so as to accumulate a reaction force by elastic deformation, wherein the spring member is formed into a frame-like shape extending along the first and second members.

A structure for connecting members, comprising:
- a first member having stiffness;
- a second member movable relative to the first member and having stiffness;
- a spring member having a first end portion connected to a rear portion of the first member and a second end portion connected to a rear portion the second member so as to accumulate a reaction force by elastic deformation,
- a back frame comprising at least a pair of the lower frame elements on the right and left,
- at least a pair of the upper frame elements on the right and left, and
- at least a pair of the spring members on the right and left for connecting one of the lower frame elements to a corresponding one of the upper frame elements,
- wherein the spring member is formed into a frame shape extending along the first and second members,
- wherein at least a portion of the spring member is spaced from said first and second members,
- wherein the first member is a lower frame element constituting a backrest lower portion of a chair,
- wherein the second member is an upper frame element constituting a backrest upper portion of the chair,
- wherein each of the right and left upper frame elements are capable of tilting independently, and
- wherein a bottom end of each of the upper frame elements on the right and left is attached to a top end of a corresponding one of the lower frame elements on the right and left, such that each of the upper frame elements on the right and left is pivotable relative to a corresponding one of the lower frame elements on the right and left.
