Abstract
A chair assembly includes a back shell member including a laterally-extending top portion, a laterally-extending bottom portion and a pair of longitudinally-extending side portions extending between the top portion and the bottom portion and cooperating therewith the defined open space therebetween, and a cover having a first surface adapted to support a seated user and a second surface opposite the first surface, wherein the cover is positioned over the back shell member to cover at least a portion of the open space, and wherein the cover comprises an elastomeric material having a longitudinal direction compliance to lateral direction compliance ration of at least 3:1.
Claims42
A chair back assembly, comprising:
- a back shell member including a laterally extending top portion, a laterally extending bottom portion and a pair of longitudinally extending side portions extending between the top portion and the bottom portion and cooperating therewith to define an open space therebetween, wherein the top portion, the bottom portion and the side portions are a single, integral piece, and wherein the back shell member is flexible in a fore-to-aft direction;
- a cover having a first surface adapted to support a seated user and a second surface opposite the first surface, wherein the cover is positioned over the back shell member to cover at least a portion of the open space;
- and
- a ring member having a plurality of side portions and a plurality of corner portions interspaced with the side portions, wherein at least one of the side portions is secured to the first surface of the cover such that the at least one of the side portions is fixed for rotation with the cover along a longitudinal axis of the at least one of the side portions, and wherein at least one of the corner portions is secured to the first surface of the cover such that the at least one of the corner portions is free from rotation with the cover along a line tangential to the at least one of the corner portions, and wherein the mesh fabric cover is fixed for rotation with the at least one of the side portions of the ring member as the ring member is wrapped about the support component and the mesh fabric cover is free from rotation with the at least one of the corner portions as the cover member is wrapped about the support component.
