Abstract
Abstract The backrest (2), particularly for a motor vehicle seat, includes padding (3) in which grid elements (B, 10) with tensioning means (12, 16) are incorporated in correspondence with the dorsal and sacral regions respectively. The front region (6) of the padding (3) assumes a slightly curved vertical profile (18) when the tensioning means (12, 16) are in the rest condition, and an undulate vertical profile (18) when the actuation of drive means (12, 16) tensions the grid elements (8, 10).
