ABSTRACT:
A vehicle seat includes a back rest with lordosis support comprised of a bendable supporting element mounted on a wire grating by means of clamps carried by the supporting element. Each clamp forms a slot having a central tongue dividing the slot into first and second compartments for receiving first and second wires, respectively, of the grating. The combined widths of mouths of the two compartments is less than the combined diameters of the two wires so that the two wires cannot be inserted or removed simultaneously. The tongue is flexible to enable the two wires to be inserted or removed sequentially.
