Sinuous Spring Loading Surface Supported By Other Spring Patents (Class 267/87)
  • Patent number: 9622585
    Abstract: A seat cushion structure of chair is provided, in which a seat cushion body has a chamber provided on its upper end surface. The chamber has holders provided on its two opposite walls, and a plurality of spring steel wires have their two ends fixed on the holders provided on the opposite walls of the chamber so as to span across the chamber. An elastic pad covers correspondingly the upper end surface of the seat cushion body in such a manner that user, when sits on the elastic pad, enjoys comfortable and elastic feeling by the support of the elastic pad and the spring steel wires provided under the elastic pad. Furthermore, user's body heat can be dissipated through perforations provided on the elastic pad to the chamber of the seat cushion and thus to the outside, so as to enhance user's comfort.

  • Patent number: 6793289
    Abstract: A seat back or a seat base of an automobile seat with a frame includes a spring system extending between two opposing cross braces consisting of meander-shaped shaped spring wires and upholstery in a seat surface. The level determined by the supporting surface of the shaped wire springs may be so changed by tension belts passing through the shaped wire springs at different tensions that it is more strongly arched when the belts are in relaxed condition than when they are tightened.

  • Patent number: 6647574
    Abstract: A coupled waveband (14, 21) suspension for bed underframes, seating, upholstery, and mattresses consists of several sinusoidal wavebands (14, 21) which run parallel and/or transversely to the longitudinal axis. Support elements (12, 35) are rigidly or moveably fixed to or ride on the crests or maxima of the wavebands (14, 21). The troughs or minima are supported by slide or roll bearing elements (17) affixed to the frame. A strong interactive coupling is achieved between the support elements (12, 35) causing a positive stroke of the less pressure-loaded segments and the appropriate support elements by the simultaneous lowering of the pressure-loaded waveband segments. The wavebands (14, 21) are manufactured out of higher quality, elastically flexible sold plastic or foam material, or of spring steel band or wire, duralumin, or out of formed laminated wood.
