Abstract
An orthotic or prosthetic spacer element including a ventilated and compressible core having first and second opposed surfaces, and a discrete and continuous web-like silicone-based frictional layer secured to the core first surface. The frictional layer and the core first surface have a plurality of coinciding apertures formed in a pattern. The spacer element may include a foam layer secured to the core second surface such that the foam layer and the core have different rigidities. A layer of hook-receivable material may be directly or indirectly secured to the second core surface.
Claims26
An orthotic or prosthetic spacer element, comprising:
- a three-dimensional knit fabric having first and second surface layers spaced by a ventilated and compressible core, the first surface layer being a fabric mesh forming a plurality of uniformly spaced apertures arranged in a pattern and having a predetermined shape;
- a discrete and continuous frictional layer defined as a sheet of silicone elastomer laminated onto the first surface layer, the frictional layer having a plurality of apertures arranged in a pattern, the pattern of the frictional layer apertures are in direct correspondence to the pattern of the first surface layer apertures, the apertures of the frictional layer having the same shape as the apertures formed by the first surface layer, wherein the apertures of the frictional layer open over the ventilated core and are formed independently from the core;
- wherein the frictional layer extends continuously over the first surface layer in areas outside of the apertures formed by the first surface layer.
A ventilated orthotic or prosthetic spacer element, comprising:
- a three-dimensional knit fabric having first and second surface layers spaced by a ventilated and compressible core, the first surface layer being a fabric mesh forming a plurality of uniformly spaced apertures arranged in a pattern and having a predetermined shape;
- a discrete and continuous frictional layer defined as a sheet of silicone elastomer laminated onto the-first surface layer, the frictional layer having a plurality of apertures arranged in a pattern, the pattern of the frictional layer apertures are in direct correspondence to the pattern of the first surface layer apertures, the apertures of the frictional layer having the same shape as the apertures formed by the first surface layer, wherein the apertures of the frictional layer open over the ventilated core and are formed independently from the core;
- wherein the frictional layer impregnates the first surface layer and extends continuously over the first surface layer in areas outside of the apertures formed by the first surface layer;
- and
- a layer of hook-receivable material secured to the core second surface.
