SHEET MATERIAL FOR SEAT

摘要

A sheet material for a seat, characterized in that a stress (A) generated when the sheet material is extended by 5% in one of the vertical and lateral directions whichever the stress is larger is 40 to 300 N/4 cm wide, the ratio (A/B) of the stress (A) to a stress (B) generated when the sheet material is extended by 5% in the other direction is 1.5 to 15.0, and a width-in percentage (H) when the sheet materials fixed to two sides are stretched and compressed is 0 to 15%.
