▎ 摘　　要

NOVELTY - The cushion has a cushion unit (100) with a built-in heating element (110). A temperature sensor (120) is attached to the heating element. A control unit (160) automatically controls the supply of current based on the temperature measured by the temperature sensor. The cushion unit is divided into multiple sections and folded. The heating element is located in some of the sections of cushion body and is detachable from the cushion unit. A latent heat material is embedded in the cushion part for maintaining the temperature by using the heat transferred from the heating elements, which are made of carbon fiber (112) or mixture of the carbon fiber and graphene. USE - Used as portable cushion e.g. chair. ADVANTAGE - The portable cushion comprises a cushion unit that is provided with a built-in heating element, where control unit automatically controls the supply of current to the heating element based on the temperature measured by the temperature sensor, and thus enables to improve the durability and provides easy handling. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view showing a portable cushion. Cushion unit (100) Heating element (110) Carbon fiber (112) Temperature sensor (120) Control unit (160)
