Title:

BASE NET AND SEAT STRUCTURE

Document Type and Number:

WIPO Patent Application WO/2013/077437

Kind Code:

A1

Abstract:

In order to improve posture supportiveness, body pressure dispersiveness, energy absorbency, and the like, a base net (170) for a back is formed from a three-dimensional stereoscopic knit, and has a configuration in which seams (171a-171d) for bringing a pair of ground knitted fabrics thereof to close to each other in a thickness direction are partially provided, predetermined preliminary compression is applied in the thickness direction by the seams, and thereby residual stress is generated in a surface direction (stretching direction). Therefore, stiffness is partially increased by partial improvement in residual stress, and consequently a human body with extreme roughness is supported by nearly uniform pressure. Thus, in spite of a simple configuration in which the seams (171a-171d) are provided in desired regions, posture supportiveness and body pressure dispersiveness can be improved. Further, by arbitrarily adjusting the formation positions of the seams (171a-171d), the pressure distribution is adjusted, thereby making it possible to easily control the vibration mode to desired setting, and easily improve vibration absorbency.
