Abstract:
The purpose of the present invention is to improve cushion pad durability and obtain a product that does not cause the feeling that a foreign body is present. The present invention provides a cushion pad deformation detection system that comprises: a cushion pad comprising a magnetic elastomer in which a magnetic filler is dispersed in an elastomer and the arithmetic mean roughness (Ra) is 0.5-10 µm and a soft polyurethane foam that is integrated with the magnetic elastomer by bonding; and a magnetic sensor that detects a magnetic change that is caused by deformation of the cushion pad. The present invention also provides a production method for the cushion pad deformation detection system.
