Elastic belt chair rest part

Abstract

This invention relates to an elastic belt chair rest part realized by an elastic belt chair consisting of or comprising the surrounding frame and the backed seat. The backed seat includes a seat and a back. The seat is made of the same material for the surrounding. It is characterized in that the back is woven by tensioned elastic belts, and the two belts ends are respectively fixed to the surrounding frame and seat. This brings a novel and unique shape, and more substantial and comfortable fit and feeling. The sitter will feel no deformation and reduced tension in the hip area. The back can be forcefully supported by the elastic belts woven in a Z shape. Additionally, the belts can be made from colorful and foldable elastic belts with the surrounding frames in different colors.
