MUMBAI, India, Nov. 14 -- Intellectual Property India has published a patent application (202517096437 A) filed by Toyota Boshoku Kabushiki Kaisha; and Nihon Tokushu Toryo Co. Ltd., Aichi, Japan, on Oct. 7, for 'vibration damping sheet.'
Inventor(s) include Nagano Masahiro; Watanabe Yuji; and Kawamura Hiroshi.
The application for the patent was published on Nov. 14, under issue no. 46/2025.
According to the abstract released by the Intellectual Property India: "A vibration damping sheet 10 comprises: a sheet body section 30 that is non-air-permeable and flexible; and a plurality of support sections 32 that are formed so as to protrude from the sheet body section 30 at mutual intervals, and that each have a tip surface 32 contacting a floor panel 12 that is an object, thereby supporting the sheet body section 30. Portions of the tip sides of the plurality of support sections 32, including the tip surfaces 32a, are viscoelastic and magnetic; and the attractive force per unit area of the vibration damping sheet 10 due to magnetism is at least 24 Nf/m2 and no more than 390 Nf/m2. Due to this configuration, at least 300-500 Hz of vibration can be effectively attenuated. The vibration damping sheet 10 can be used without being fused to an object and can exhibit high vibration damping performance without having a high mass."
The patent application was internationally filed on Feb. 09, 2024, under International application No.PCT/JP2024/004562.
