The invention discloses a low-friction safety belt integrated on a truck seat. The safety belt comprises a safety belt body, the upper end of the safety belt body is movably wound around an upper hanging ring, a back guide plate is arranged below the safety belt body, a plurality of protruding point structures are arranged on the face, making contact with the safety belt body, of the back guide plate, and the protruding point structures make point contact with the safety belt body. By adopting the structure of the lifting ring shaft and the shaft sleeve, rolling fit between the safety belt and the upper lifting ring is realized, so that friction force between the safety belt and the upper lifting ring during pulling is reduced; the backrest guide plate adopts a convex point type structure and is in point contact with the safety belt, so that the friction is effectively reduced, and the safety belt wearing comfort of passengers is improved.
本发明公开了一种集成在卡车座椅上的低摩擦安全带。它包括安全带,所述安全带上端活动绕于上吊环上,所述安全带下方布置背部导向板,所述背部导向板与安全带接触的一面设有多个凸点结构,所述凸点结构与安全带点接触。本发明通过采用吊环轴与轴套结构,实现安全带和上吊环之间的滚动配合,从而减小织带在拉动时两者之间的摩擦力;靠背部导向板采用凸点式结构,与安全带点接触,有效降低摩擦,提升乘员佩戴安全带的舒适性。
