Abstract:
1. A resilient shock-absorbing device comprising: an absorber body having top and bottom faces and including first and second absorber layers; said first absorber layer having said top face and including a plurality of longitudinal resilient first outer tube halves of substantially arc-shaped cross section juxtaposed in parallel and heat-sealed to each other, a plurality of first heat-seal seams, and a plurality of first foam members filled respectively in said first outer tube halves and each having a surface exposed from a respective one of said first outer tube halves, each of said first outer tube halves having two transversely opposed first longitudinal ends contacting directly and respectively adjacent said first longitudinal ends of two adjacent said first outer tube halves, each of said first heat-seal seams extending longitudinally and interconnecting two adjacent said first longitudinal ends that contact each other; said second absorber layer having said bottom face and including a plurality of longitudinal resilient second outer tube halves of substantially arc-shaped cross section juxtaposed in parallel and heat-sealed to each other, a plurality of second heat-seal seams, and a plurality of second foam members filled respectively in said second outer tube halves and each having a surface exposed from a respective one of said second outer tube halves, each of said second outer tube halves having two transversely opposed second longitudinal ends contacting directly and respectively adjacent said second longitudinal ends of two adjacent said second outer tube halves, each of said second heat-seal seams extending longitudinally and interconnecting two adjacent said second longitudinal ends that contact each other; each of said first and second outer tube halves being made of a thermoplastic elastic material.
