SYSTEM FOR DETECTING DEFORMATION OF CUSHION PAD AND PROCESS FOR PRODUCING SAME

摘要

The purpose of the present invention is to obtain a deformation detection system which includes a cushion pad having improved durability and not giving a feeling that foreign matter lies. The invention provides a system for detecting a deformation of a cushion pad, the system comprising: a cushion pad that is configured of a matrix layer in which an electroconductive or magnetic filler has been dispersed and a foamed flexible polyurethane object in some of which the matrix layer has been disposed; and a detection part that detects an electrical or magnetic change attributable to a deformation of the cushion pad. The system is characterized in that the matrix layer has a lower hardness than the foamed flexible polyurethane object. Also provided is a process for producing the system.
