Abstract
A cushioning structure includes a first layer of a three-dimensional structured mat of extruded entangled filaments, the cushioning structure includes a second layer of a three-dimensional structured mat of extruded entangled filaments, and the cushioning structure includes an intermediate layer between the first layer of the three-dimensional structured mat and the second layer of the three-dimensional structured mat.
Claims18
A cushioning structure comprising
- a first layer of a three-dimensional structured mat of extruded entangled filaments,
- a second layer of a three-dimensional structured mat of extruded entangled filaments and
- an intermediate layer between the first layer and the second layer, wherein
- at least one of the first layer and the second layer is created by extruding polymeric filaments and collecting the polymeric filaments on a three-dimensional profiled surface, which results in the filaments bending, entangling and coming into contact with each other to form a three-dimensional structure conforming to the three-dimensional profiled surface, and
- the three-dimensional structure comprises hills and valleys, hemispheres, positive and/or negative cuspates, cups and/or waffles, pyramids, U-grooves, V-grooves, cones and/or cylinders capped with a hemisphere.
