Automobile backrest framework

Abstract

The invention provides an automobile backrest framework. A framework body comprises a framework frame, an upper protective plate, a middle protective plate and a lower protective plate which are integrally molded; a shock absorbing pad is laminated on the framework frame; the thickness of the shock absorbing pad is 2-3 mm; the upper protective plate comprises four upper fixing holes which are distributed at equal intervals; the upper protective plate and the middle protective plate are partitioned by a reinforcing rib; the middle protective plate comprises an adjusting fixing hole, a middle fixed hole and an electric welding part, wherein the adjusting fixing hole is formed in the middle part, and the middle fixing hole and the electric welding part are arranged on two sides of the adjusting fixing hole; the middle protective plate is partitioned from the lower protective plate by using a reinforcing rib; a plugging port fixed together with an automobile body is formed in the bottom ofthe lower protective plate; a pressing groove is formed in the plugging hole; and an inwardly folding flanging part is arranged on the left side of the lower protective plate. The automobile backrestframework has the advantages that the connection between the backrest framework and the automobile body can be enhanced by using a multi-fixing mode; meanwhile, the shock can be actively absorbed byusing the shock absorbing pad to improve the taking experience.

Description

technical field [0001] The invention belongs to the field of automobile backrest seat components, in particular to an automobile backrest frame. Background technique [0002] The interior of the vehicle is provided with a seat for a passenger to sit on.
