    Abstract: A vehicle seat and a seat back board are obtained in which a seat cover can easily be anchored to a resin spring. In a seat back board, clips attached on a cover side are engaged with vertical clip engagement portions of the seat back board, thereby enabling the cover to be anchored to a back spring section of the seat back board. An anchoring operation of the cover to the back spring section can accordingly be made easier than in conventional anchoring structures employing for example hog rings. Moreover, since only pairs of openings are formed to the back spring section of the seat back board in order to provide the vertical clip engagement portions, any detriment to the moldability of the back spring section can be avoided.

  • Patent number: 7090300
    Abstract: The structure is formed by serially connecting a torsion bar and a coil spring via a arm and a supporting frame to thereby elastically support a flat-type supporting member, and by disposing a cushioning member for seat cushion provided with a spring characteristic closely analogous to a load-to-deflection characteristic (spring characteristic) of the muscle of a human body above the flat-type supporting member. Accordingly, it is possible to make a spring characteristic for working when supporting a load of a human different from a spring characteristic for working when removing vibration even with an extremely simple structure. In other words, the structure has an excellent function to make the spring constant at work when removing vibration, especially when removing a high frequency component.

  • Patent number: 6854804
    Abstract: A seat cushion extends across left and right areas that are located beneath the locations of the left and right ischial tuberosities of a seated person. A support structure beneath the cushion transmits a weight load from the cushion to the seat frame. The support structure has portions that surround the left and right ischial areas to provide the cushion with underlying, load bearing support at the peripheral boundaries of the ischial areas, and is free of load bearing portions located within or beneath the ischial areas.

  • Patent number: 6848156
    Abstract: A method of making a motorcycle backrest which has a back support cushion with a handhold aperture, and a support arm for mounting the backrest on a motorcycle saddle or frame uses a mold with a cavity and central post. A rigid frame is encapsulated in a rigid resin base and a cushion layer is formed thereon. The base and cushion layer have an aperture extending therethrough. The flexible cover is formed about the cushion layer and about the periphery of the backrest structure and through the aperture, and it is secured to the surface of the rigid base. A protective cover plate is secured over the cover on the rigid base.

  • Patent number: 6676218
    Abstract: An object of the present invention is to minimize the dependency of the vibration characteristic exhibited by the sheet-shaped supporting member supported by the metal springs on the added load. In a plurality of metal springs 41 to 44 supporting a sheet-shaped supporting member 30, a third metal spring 43 provided on the position to support the vicinity of the greater trochanter of the seated person is provided in a manner that an engagement portion with a frame member is positioned lower than the engagement portion with the sheet-shaped supporting member 30 when no load is applied. Accordingly, the feeling of something foreign created by such a third metal spring 43 can be reduced, and within a predetermined range of the added load, the third metal spring does not work functionally because respective engagement portions 43a and 43b take their positional relationship to be substantially horizontal in a static seating state, while it works functionally when the added load exceeds the above-described range.

  • Patent number: 6499807
    Abstract: A seat back frame assembly of the invention has side frame members (17, 17), an upper frame member (18), a lower frame member (19) and zigzag spring (15) mounted between the side frame members (17, 17). A side portion (27) of the lower frame member has a main connection portion (28) and a sub-connection portion (29), both of which are fixed to the side frame member (17). The main connection portion (28) is positioned below the zigzag spring (15). The sub-connection portion (29) is inclined toward a front upper side so that the sub-connection portion and the zigzag spring are at least partly overlapped with each other in a front-and-back direction.

  • Publication number: 20020125759
    Abstract: A method of manufacturing a seating unit, such as a chair, includes manufacturing a cushion made from a non-woven fibrous material, and attaching the cushion to the seating unit for comfortable support. The cushion is made by cutting a blank from non-woven fibrous sheet material, steam-forming the blank into a pre-formed cushion shaped to support a user, and attaching a stiffener panel to the pre-formed cushion to provide a stiffened cushion assembly. The cushion assembly is aesthetically covered and assembled to seating unit. Advantageously, trimmings from the fibrous material can be recycled.

  • Patent number: 6193318
    Abstract: A sitting and/or lying arrangement, particularly a vehicle seat or airplane seat, has a stable subframe and a flexible support which has a base part and a cushion. For creating such an arrangement, in which the user's body is anatomically correctly supported such that the body can relax and no pressure points are formed, the base part consists of a transversely stiff but longitudinally flexible material and is implemented, for example, by a thin, corrugated spring plate made of spring steel, carbon fibers, glass fibers or kevlar fibers, titanium and the like.
