A cushion has provisions for a support (3), to attach a gear box (5), and an other support (2) to attach a rail (11), on which a slider (12) travels back and forth. The slider (12) is pushed along the rail (11) by a lead screw (7) actuated by a worm gear/nut (6), rotated by a worm (10). The worm gear/gear nut (6) and the worm (10) are part of the gear box (5). The worm (10) has a kinematic couple (8) connecting to a motor (9), which is the original source of power in the system. The slider (12) is coated with a nylon skate (14), and is provided with a rotating joint B, which accommodates one end of the link (13). The other end of the link(13) is attached to a paddle (1) through an other rotation joint C. When the motor (9) rotates the worm (10), the worm gear/nut (6) rotates and pushes the lead screw (7) forward together with the slide (12), along the rails (11). The lower joint B of the link (13) is pushed forward and th upper joint C of the link will push the paddle (1) up, rotating it relative to joint A, and subsequently extending the cushion.
