  • Body-contact protective interface structure and method
    Publication number: 20020152542
    Abstract: A plural-layer body-contacting protective and cushioning interface structure. This structure has a body-facing side which contacts the body, and an opposite side, and intermediate these sides, in one form of the structure, is a moisture-wicking layer, next a moisture-blocking, gas-permeable barrier layer adjacent the moisture-wicking layer, and next, an acceleration-rate-sensitive cushioning layer. In some applications, the moisture-wicking layer is omitted.

  • Cushioning shoe insole with plural, differentiated surface-tension cushioning
    Publication number: 20020144433
    Abstract: A shoe insole structure which includes a singular (or plural) acceleration-rate-sensitive, differentiated-softness, bonded viscoelastic cushioning layer(s), joined to the upper surface of which is a low-surface-friction, moisture-wicking fabric overlayer. The overall insole presents to a foot an effective upwardly facing support surface which has an effective surface tension which is lower than (differentiated from) that of the underside of the foot.

  • Scissor jack lumbar support
    Patent number: 5553919
    Abstract: A lumbar support for a seat back having a support platform that extends and retracts by operation of lever arms. The present invention generally includes a support frame and a rigid support platform suspended within a seat back. The support platform is mounted to the support frame by lever arms preferably arranged in a scissors jack configuration. A control mechanism having a Bowden cable and a rotary control is provided to selectively pivot the levers and cause the support platform to extend and retract with respect to the support frame.
