| 20080284230 | Backrest For Chair - In order to secure a shape retaining property of a support face of a backrest | 11-20-2008 |
| 20090015054 | SEATING UNIT WITH FORMED CUSHION, AND MANUFACTURING METHOD - A cushion subassembly includes a support, a cushion of non-woven polymeric (PET) or PETE fibers with a formed edge that wraps over an edge of the support, and an upholstery sock pulled onto and covering the support and the cushion. The formed edge has sufficient mechanical structure to retain the cushion on the support as the upholstery sock is pulled onto the support. A back support shell supports the cushion assembly, and has first fasteners that engage in a first direction and second fasteners that prevent disengagement. The cushion assembly is stressed during assembly, especially at corners, but is thermally stress-relieved after assembly to relax the polymeric fibers and the upholstery sock to a state of minimized balanced tension. The back support shell includes a shallow depression on its face. The cushion fills the depression sufficient to eliminate loose fabric but provides a same force deflection curve across its shape. | 01-15-2009 |
| 20090273221 | ERGONOMIC CHAIR - An improved ergonomic chair, including a chair base, a chair cushion and a chair back located to the rear of the chair base. Support strength of cushion pads on the chair back assumes a fan-shape extending from a lower end towards the upper end, thereby dispersing the compressive stress on the lower back and supporting the back of a person. A support cushion is located on the chair back corresponding to the cervical vertebra of a person, and a head cushion, provided with a plurality of depressions, is located on the chair back above the support cushion. Accordingly, the design of the support cushion and the head cushion facilitating the dispersal of the compressive stress on the lower back and support of the back and cervical vertebra provide the chair back with the ability to appropriately support the cervical vertebra, thereby enabling neck pains to be avoided when sitting. | 11-05-2009 |
| 20100001572 | CHAIR BACKREST DEVICE - A backrest device for a chair, capable of, without a reduction in its strength and rigidity, effectively bending backward so as to follow the shape of the back of a person seated on the chair, providing the person with excellent sitting comfort. In the backrest device, a back board is supported by a backrest frame, and the back board has a flexible back stopper on the inner side of a back frame. The thickness of a vertical intermediate section of the back stopper is gradually increased from both left and right sections of the intermediate section toward the center such that the thickness is less in both left and right sections and is maximum at the center. | 01-07-2010 |
| 20120062014 | BACKREST - A backrest includes a shell having a first, forwardly facing support surface being more pronounced along upper and lower portions of a central, spine region relative to a middle portion of the central spine region and relative to side regions adjacent the central, spine region. A cushion is disposed over the first support surface. In one aspect, the cushion has a second, forwardly facing support surface being free of any corresponding pronounced portions overlying the pronounced upper and lower portions of the central, spine region of the underlying shell. In another aspect, a chair includes a backrest as disclosed. Methods of use and assembly also are provided. | 03-15-2012 |
| 20140077574 | BACKREST MECHANISM FOR CHAIR - A backrest mechanism for a chair includes a pair of left and right side rods, each having a folded portion in a laid-V shape in a side view at a portion for supporting a sitting person around his or her lumbar, and a back plate that connects opposing surfaces of the side rods. An upper portion of the back plate above the folded portions serves as a flexible portion that is elastically deformable in a backward direction and that has smaller rigidity than the left and right side rods, and a lower portion of the back plate below the flexible portion serves as an inflexible portion that has greater rigidity than the flexible portion. | 03-20-2014 |

| 20120181840 | INTEGRAL COCCYX AND LUMBAR SUPPORT SYSTEM - A seating support includes a lumbar support portion having first and second lumbar supports. The lumbar support portion defines at least a portion of a channel extending between the first and second lumbar supports. The channel is sized to substantially preclude contact with an occupant of the seating support. Such a seating support also includes a coccyx support portion having first and second coccyx supports. The coccyx support portion is disposed substantially perpendicular to the lumbar support portion and is in communication therewith such that the channel extends from the lumbar support portion between the first and second coccyx supports. | 07-19-2012 |
| 20120326483 | BACKREST MADE OF PLASTIC COMPRISING FUNCTIONAL ELEMENTS MADE OF OR COATED WITH PLASTIC - A backrest is provided, whereby a frame-shaped base structure of which is made of a dimensionally stable plastic, The base structure being formed from beams. The frame-shaped base structure includes at least one functional element between the beams, and the at least one functional element is made only of a plastic and/or as a plastic-coated insert. Injection molding is proposed as a production method. | 12-27-2012 |

| 20080265649 | Lumbar and Bolster Support for Second Row Seat - The present invention is a lumbar and bolster support for a seat, especially for an automotive second row seat or a chair back rest. The lumbar and bolster support has a lumbar support member adjustable between a retracted position and an extended position, and a first bolster member and a second bolster member adjustable between a first position and a second position. | 10-30-2008 |
| 20110241403 | SEAT BACK FOR VEHICLE AND SEAT FOR VEHICLE INCLUDING THE SAME - A waist receiving portion, which is provided at a support member, is curved to form a convex shape toward a front side in a seat front and rear direction in side view. Accordingly, when a waist portion of an occupant is pressed against the waist receiving portion, the change of the shape of lumbar vertebrae is suppressed. For this reason, since it is possible to reduce the difference between a timing when a head portion of the occupant is pressed against a headrest and a timing when a neck portion of the occupant is pressed against a neck receiving portion, it is possible to suppress swing of the head portion of the occupant about the neck portion as a fulcrum in the seat front and rear direction. Therefore, a burden to the neck portion of the occupant is reduced. | 10-06-2011 |

| 20080258534 | CHAIR BACKREST WITH INTEGRAL LUMBAR SUPPORT - Chair backrest, comprising a support structure constituted by a single piece of injected plastic material, including a bearing section having a front surface against which a user's back is to bear. The bearing section has an opening that extends in a lumbar region of the front surface. The backrest comprises a lumbar support panel movably positioned in said opening. The lumbar support panel has a front surface against which a lumbar region of the user's back is to bear and it has an outer perimeter that is connected to the edge of said opening by means of an elastic element that tends to thrust the support panel towards a position in which the front surface of the lumbar support panel projects anteriorly relative to the front surface of said bearing section. | 10-23-2008 |
