  • Patent number: 10035440
    Abstract: [Problem] To provide a cushion pad that reduces the wobbling feeling. [Solution] Regarding the test piece sampled from a core portion, the measured deflection under a load of 100 N during compression is equal to or less than 30 mm. The measured static spring constant under a load of 300 N at a pulling rate of 20 mm/minute is equal to or less than 25 N/mm. In the case of a vibration input in a low frequency band in the lateral direction, the compressive stress in the vertical direction due to the weight of a seated person and the tensile stress due to the vibration input in the lateral direction act on the support portion. The direction (gradient) of the resultant force as a combination of the compressive stress and the tensile stress can be closer to the vertical direction. This allows reducing the wobbling feeling.
