CUSHIONING ELEMENTS COMPRISING ELASTOMERIC MATERIAL AND METHODS OF FORMING SAME

Document Type and Number:

WIPO Patent Application WO/2012/148915

Kind Code:

A3

Abstract:

Cushioning elements include a porous foam comprising a series of interconnected cell walls and an elastomeric material formed over at least a portion of the interconnected cell walls. The porous foam is configured to allow gases to pass through at least a portion thereof. Methods of forming cushioning elements may include coating interconnected cell walls of a breathable porous foam with a liquid comprising an elastomeric material, solidifying at least a portion of the elastomeric material, and providing a gas path through the elastomeric material. Other methods include pressing sheets of foam together at a pinch point, disposing a liquid between the foam over the pinch point, coating the foam with the liquid, and separating the sheets beyond the pinch point. Some methods include consolidating a plurality of portions of porous foam into a continuous cushioning material.
