    Abstract: The present invention provides an improved vehicle seat pan and a method for controlling vertical deflection in a vehicle seat pan. A vehicle seat pan in accordance with the present invention includes a frame adapted to be mounted to a vehicle body. A suspension web for supporting a seat cushion is mounted to the frame. A vertical deflection controller is coupled between the web and the frame. The controller may be a leaf spring. Additionally, the controller may be a coil spring and a metal strap that limits the extension of the spring. A method for controlling vertical deflection in a vehicle seat pan is also provided. The method includes the step of mounting a substantially horizontal suspension web to a seat frame. The method further includes the step of coupling a vertical deflection controller between the web and the frame.

  • Patent number: 6749261
    Abstract: A seating unit includes a seat and back operably supported for synchronized reclining movement. The back includes a back support with separate upper and lower portions pivotally coupled to a back frame at upper and lower connections, respectively. The upper and lower portions combine to define a forwardly-protruding convex shape and include mating structure forming an expansion joint that permits collapse and expansion as the upper and lower portions are flexed between a more-convex shape and a more-planar shape. In one form, the lower portion includes first and second sections pivoted together, with the upper portion and the first and second sections forming thoracic, lumbar, and pelvic regions of the back support, respectively.

  • Patent number: 6722735
    Abstract: A chair having a synchronously moving seat bottom and seat back includes a frame having a seat bottom support portion and a seatback support portion and a seat assembly having a seat bottom and a seat back interconnected by a flexible intermediate portion. The seat bottom is slidably mounted to side support members in the bottom frame providing forward and aft movement of the seat bottom. The seat back is pivotably engaged to the seat back support portion of the frame. The flexible intermediate portion provides for cooperative movement of the seat bottom and seat back between an upright seating position and a reclined position. Preferably, the seat assembly is a one piece molded plastic shell having a flexible intermediate portion interconnecting the seat bottom and seat back. In one embodiment of the invention, the chair can be provided with legs to enable stacking of the chairs.

  • Patent number: 6669301
    Abstract: A furniture component, such as a chair back or seat, includes a panel component made of a flexible compliant plastic, and a rigid tubular perimeter frame integrally molded onto and hence bonded to a perimeter flange of the panel component to structurally support the panel component. The panel component includes horizontally extending flexible strips shaped to provide comfortable support for a seated user. The perimeter frame extends continuously around the enlarged show area and is made by gas assist processes, which cause the perimeter frame to be tubular and hollow for increased strength-to-weight ratio. Methods related to the above are also disclosed.

  • Patent number: 6446945
    Abstract: A recoil strap for use with a vehicle seat frame bottom, the frame having an open interior defined by inwardly facing side edges, apertured portions being defined along a first side edge of the frame and clasp portions being defined along a second side edge. The strap includes an elongated and substantially planar shaped body, constructed of a stamped and spring steel blank, and having a first end and a second end. A plurality of catch portions extend from the first end for securing to the aperture portions of the frame bottom and a plurality of eyelet portions extend from the second end for securing to the clasp portions of the frame bottom. The strap is biased in an upward direction, and in response to a downward application of force, by at least one plurality of alternating bends and recesses formed in the stamped blank. The stamped blank may also include an arcuate curvature to provide additional biasing and resistive support to the seat bottom.

  • Patent number: 6296315
    Abstract: Seating furniture can be configured for mounting on a carrier element. The carrier element may be part of a stand in a stadium, a frame for a park bench or a carrier element mounted on other established foundations or on other natural foundations. The chair distinguishes itself in that the chair can be mounted on or demounted from the carrier element without difficulty. The chair includes a profile provided with jaws extending around the carrier element and which is fastened to the carrier element. As a result, it is much faster to provide new seats, for example in a stadium, and it is easier to replace individual chairs which may have been damaged. In a preferred embodiment the chair is provided with a pivotable seat. In alternative embodiments, a back of the chair is also pivotable, just as the seat and the back may extend over more seats and thus constitute a bench.

  • Patent number: 6257665
    Abstract: A chair comprises a back cushion material, a back plate and a back frame. The chair is used for looking at a display of a personal computer at suitable posture when it is reclined. The back plate comprises upper and lower shell which are connected by a flexible bent portion to each other. The back plate is mounted to the back frame at the upper end and a lower portion. When the chair is reclined, the upper shell is moved forwards and the lower shell is moved rearwards, so that an angle between the upper and lower shells may become smaller. Thus, the operator can take suitable posture for looking at the display any time.

  • 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.
