Abstract
A structure for use in a compressible resilient pad. The structure contains both axially elastomeric strands and relatively inelastic strands co-extruded in various patterns. The structure has a high degree of both compressibility under an applied normal load and excellent recovery (resiliency or spring back) upon removal of that load.
Claims28
A bicomponent mesh having layers of parallel strands formed by extrusion, comprising:
- a first layer of the parallel strands running in a longitudinal direction;
- a second layer of the parallel strands on one side of the first layer, the second layer's strands running in a second direction and comprising elastomeric strands;
- and
- a third layer of the parallel strands on the opposite side of the second layer as the first layer and running in the same direction as those of the first layer,
- wherein the first, second, and third layers are co-extruded at substantially the same time such that the strands in the first layer are positioned or aligned within the space between strands in the third layer,
- wherein the first, second, and third layers form a structure having a desired thickness,
- wherein under a compressive load the second layer stretches to enable the strands of the first and third layers to nest between each other in substantially the same plane, and
- wherein upon release of the compressive load elasticity of the second layer causes the first and third layers to spring back returning the structure to substantially the desired thickness.

A bicomponent mesh having layers of parallel strands formed by extrusion, comprising:
- a first layer of the parallel strands running in a longitudinal direction;
- a second layer of an elastic material on one side of the first layer;
- and
- a third layer of the parallel strands on the opposite of the second layer as the first layer and running in the same direction as those of the first layer,
- wherein the first, second, and third layers are co-extruded together such that the strands in the first layer are positioned or aligned within the space between strands in the third layer,
- wherein the first, second, and third layers form a structure having a desired thickness,
- wherein under a compressive load the second layer stretches to enable the strands of the first and third layers to nest between each other in substantially the same plane, and
- wherein upon release of the compressive load elasticity of the second layer causes the first and third layers to spring back returning the structure to substantially the desired thickness.
