Abstract
In order to soften or stiffen the support offered by an elastic sheet, and in particular a vehicle seat back, the device comprises a flat spring (1) which is at each of its ends connected to the sheet (38), and fixed to a case (2, 3) containing an inclined disc (10, 12). Two discs are fixed to a control rod (24) which is mounted in the frame (36) of the seat and, when this rod is rotated, they cause the cases to be pivoted symmetrically, so that the spring is extended and stiffens the sheet or is shortened and renders the seat more soft.
