US Patent 11760240 Surface skin, molded product, and vehicle seat

A surface skin with which a foamed body is integrally foam-molded and which covers the foamed body includes: a plurality of surface skin members; a first thread passing through at least a part of a needle hole extended through the surface skin members so as to sew the surface skin members together; and a second thread inter-looping or interlacing with the first thread so as to sew the surface skin members together in cooperation with the first thread. The first thread is threaded through an eye of a needle. The second thread is formed by warp weaving or braiding polyester or nylon fiber pieces and is stretchable enough to fill in the needle hole.
