Pad carrier for e.g. backrest of vehicle seat, has grid-shaped structure made of spring steel wire, where longitudinal and transverse strands of structure and shaping wire are firmly connected with each other without welding rod materials

摘要

The carrier (1) has a grid-shaped structure made of spring steel wire and comprising two longitudinal strands (2) that are extended at distance from each other. The longitudinal strands, two transverse strands (3) of the grid-shaped structure and a shaping wire (4) comprise the spring steel wire with 0.35 to 1.00% carbon contents and tensile strength of 1.200N/mm 2. Diameter of the transverse strands is 50% greater than diameter of the longitudinal strands. The longitudinal strands, the transverse strands and the shaping wire are firmly connected with each other without welding rod materials.
