  • Patent number: 8998337
    Abstract: [Problem] To provide a comfortable backrest chair. [Solution] A shape retaining material is formed to have radial cores 12 distributed and radially extending upward from a base plate adjacent a cut hole 4 to be fitted on a chair support frame, and a first and a second reinforcing cores 13 and 14 arranged adjacent the base plate of the radial cores 12. A core sheet is formed by attaching a first, a second and a third mesh sheets 9 to the shape retaining material. A chair sheet material is formed by attaching a first and a second buffer sheets 15 and 16 and an outer surface side buffer sheet 7 to the core sheet. A backrest portion of the chair sheet material is constructed to have a larger right and left width than the breadth of a seated person's shoulders, and when the load of the seated person is applied, right and left opposite ends of the backrest portion can be displaced in directions to approach each other due to elasticity of the core sheet.

  • Publication number: 20080290712
    Abstract: A chair has a supporting frame, a seat portion, a back portion, and a recline mechanism. The mechanism moves the seat portion upon a reclining action of the back portion. The mechanism has a rear deformable member and a front deformable member operatively connecting the seat portion and the supporting frame. The recline mechanism also has a lower deformable member operatively connecting a lower part of the back portion and the supporting frame, and a puller member above the lower deformable member. The recline mechanism is configured such that as the back portion is reclined, the lower deformable member deforms and the puller member applies a rearward pulling action which causes the seat portion to move and the front and rear deformable members to deform.

  • Publication number: 20080036266
    Abstract: A seating unit includes a rearwardly-open base frame with a pair of uprights on opposite rear side portions in spaced apart positions. A molded back has corner sections with cavities for matably telescopingly engaging the uprights, and a beam section extending between the corner sections for stabilizing the rear side portions when the molded back is engaging the uprights. A seat fastened to the base frame engages the molded back to retain the molded back on the upright sections. A cushion attached by a line of adhesive is perforated inward of the line, such that a majority of the cushion can be pulled off by tearing along the perforation line, allowing quick separation for recycling. The uprights have reduced an upper diameter for aesthetics but extend upwardly sufficiently to support armrest on the back.

  • Patent number: 6997513
    Abstract: Disclosed is a supportive chair for sitting comfortably at low heights above and relative to the ground. Preferably, the chair comprises a primary seating surface and a secondary seating surface curving around the rear of the primary seating surface to provide additional support for the user. It is preferred that the secondary seating surface be inwardly and downwardly sloped and provide a low lateral boundary for the user, thereby promoting proper alignment of the buttocks on the primary seating surface. Thus, the chair raises the buttocks and hips of the user off of the seating level, creating a relative height difference between the hips and legs. This raising of the hips relative to the legs creates a sitting posture that promotes vertical back alignment. As a result, the user is able to comfortably maintain this position with a reduced amount of back muscle strain, allowing prolonged comfortable seating periods.

  • Patent number: 6840584
    Abstract: An article of furniture made of a quasi-rigid foam material. The furniture includes a base for sitting thereon. A back support member is wrapped around the base such that a portion of the support member extends upwardly with respect to the base. The support member has a pair of ends that wrap around at least half of a cylindrical surface of the base to translate a force from an upwardly extending portion of the support member to the ends and prevent tearing of the support member from the base.
