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.

Abstract: A monolithic rail clip, formed from a single piece of material, comprising a plurality of integrated hooks spaced along an angled rail body for use in constructing a seat base. A pair of the rail clips are attached to a pair of opposing members of a frame of the seat base so that the integrated hooks form opposing pairs. A plurality of springs are attached to the hook pairs and stretch between the opposing members to define a resilient structure for supporting a furniture seat. Each rail clip is constructed by forming a plurality of tabs extending from one longitudinal edge the rail body and bending the tabs to form the plurality of hooks. The integral construction of the hooks reduces the assembly time of each rail and seat base. The monolithic construction of the rail clip provides additional structural rigidity to the seat base.

Abstract: A seat pan for an automobile vehicle includes a frame carrying a suspension lattice having two sections separated by a vertical median plane dividing the seat into right and left hand sides. A motor and crankshaft combination is connected to each section of the lattice for generating in each section of the lattice a cyclic movement including, in the upper portion of its travel, a rearward movement of translation. The cyclic movements of the sections occur with an angular phase difference therebetween.

Abstract: A lumbar support device has a seat frame, a pair of brackets connected to opposite sided of the seat frame, a pair of flexible members connected to the pair of brackets in such a manner as to respectively form a pair of center sections across the seat frame, and an actuator assembly operatively connected to each one of the flexible members. Each one of the flexible members preferably has a pair of levers on opposite sides of the center sections that rotate about the brackets. In operation, the actuator assembly selectively bows the center portions of the flexible members. The actuator assembly preferably includes a reversible gear and a pair of bowden cables that move one pair of levers when the reversible gear is rotated clockwise and move the other pair of levers when the reversible gear is rotated counter-clockwise.

Abstract: An arrangement for securing springs in a vehicle seat frame, which comprises holes formed in the vehicle seat frame and anchor members. The anchor members are each formed by a plate spring comprising a generally “U” shaped body portion and a pair of flange portions, with a whole of such metallic plate spring being coated with a synthetic resin material. Each of the anchor members is fitted in each of the holes, and each of the support springs is engaged with the generally “U” shaped body portion of each of the anchor members, whereby the support springs are secured in the vehicle seat frame. In this arrangement, a through-hole may be formed in that anchor member's “U” shaped body portion, so that other support springs of different modes may each be engaged in such through-hole, instead of being engaged with the “U” shaped body portion.

Abstract: The invention provides a tension structure for constructing a seat back of a seat for an automotive vehicle. Coil springs 3a, 3b, 4a, 4b are provided as tension members which are bridged between respective side portions 11, 12 of a seat back frame 1 and respective vertical bars 20, 21 of a tension assembly 2 in an upper portion and a middle portion. On the contrary, linear wires 5a, 5b in which one wire end is entwined and fastened to axes of the vertical bars 20, 21 and another wire end is inserted and fastened to stop rings 14, 15 of the side frame portions 11, 12 are provided in a lower portion. Accordingly, a sitting attitude is intended to be stabilized by increasing a supporting pressure of a lumbar part applied by the tension assembly 2 by means of the linear wires 5a, 5b.

Abstract: A molded foam spring seat includes a seat cushion having a bottom surface supported by a support frame having an opening therein.
