Document Type and Number:
WIPO Patent Application WO/2011/102449
Kind Code:
A1
Abstract:
Provided is a cushion pad which has the property that a core layer sags more positively than an upper surface layer and provides an excellent fit in a sitting posture. Specifically provided is a cushion pad produced from urethane form and used in a vehicle seat, wherein the viscoelastic property (tanδ1) of an upper surface layer (2) of the cushion pad at a frequency of 1 Hz at 36°C is 0.065-0.144, and the viscoelastic property (tanδn+1) of a core layer thereof at a frequency of 1 Hz at 36°C is 0.052-0.102. The ratio of the viscoelastic property (tanδn+1) of the core layer (3) at a frequency of 1 Hz to the viscoelastic property (tanδ1) of the upper surface layer (2) at a frequency of 1 Hz at 36°C is 0.7-0.8.
