Steel rib polyurethane foaming chair

Abstract

The invention discloses a steel-skeleton polyurethane foaming chair which comprises a chair seat board and a back board, with chair legs being connected under the seat board, and is characterized in that the seat board and the back board are polyurethane foaming layers in which steel skeletons are embedded; the steel skeletons are steel pipes at the both sides of the back board and the seat board and the steel pipes at the both sides are connected by transverse steel sheets; the steel pipes and the steel sheets are fixed through the welding or the connection with rivets. Since the steel skeletons are embedded in the seat board and the back board, good rigidity, high mechanical strength and large bearing capacity of the steel skeletons can ensure that the chair can firmly stand and bear large pressure; furthermore, the polyurethane foaming layers are soft, elastic, smooth and slightly rough and can provide a soft and comfortable feeling for human bodies and are breathable; additionally, the chair wall is thicker than a plastic plate and the chair has an artistic appearance and can be applicable to houses, offices and hotels with a broad range of application and high grade.
