CUSHIONING MATERIAL Russian patent published in 2018 - IPC A47C7/74 A47C27/08 

FIELD: laminated products or materials.

SUBSTANCE: cushioning material for a resilient, insulating or padding cover for objects or components, consisting of a double pile fabric which is elastically impregnated by means of resin impregnation, in which an upper fabric and a lower fabric are connected so as to be spaced apart from one another by webs that are formed from pile threads, wherein the elastically-impregnated double pile fabric forms a shape-retaining elasticity with a non-linear characteristic of a spring resulting from the presence of connecting webs having a lower characteristic region, a middle characteristic region and an upper characteristic region, the lower and upper characteristic regions having, respectively, an ascending profile, while the middle characteristic region having a non-ascending profile of a hysteresis loop, which provides the impregnated double pile fabric with internal damping capacity which is adjustable by volume weight, depending on the pile threads used and / or the hardness of resin impregnation.

EFFECT: cushion material is provided, whose spring characteristic is non-linear to form an attenuation zone.
