摘要

The method involves forming an engaging groove (16) by molding a wall (3) of a body (1), where the groove comprises a closed bulged relief placed on side walls. A lower part of the relief is cut to transform the relief into an overhanging load (20) opened in the lower part along an opening that is in contact with a hollow inner volume of the body, where the overhanging load comprises an anchoring structure (15) that cooperates with an anchoring section (11) of a liner (10) to fix the liner. An independent claim is also included for a backrest of a seat comprising a body.
