Abstract: The jack (V) comprises a tubular primary screw (10) movable in rotation and translation and provided with an outer screw thread (10a) and an inner screw thread (10b) which have opposite thread hands, a fixed secondary screw (11) engaged in the inner screw thread (10b), a nut (9) connected to the movable element and engaged with the outer screw thread (10a) of the primary screw (10). The nut (9) is composite and comprises a first nut (9a) composed of a plastics material having a good coefficient of friction and a second nut (9b) composed of a mechanically strong material. Axial forces of normal amplitude are absorbed by the plastics nut (9a), while the exceptional overloads, resulting for example from an impact on the front of a vehicle whose seat structure is provided with the jack of the invention, are absorbed by the second nut (9b). In normal operation, the friction between the plastics nut (9a) and the screw (10) are considerably reduced, which provides a jack having an excellent efficiency.

Abstract: The latch comprises a keeper (2), a fork member (3) provided with two branches (7, 8) for retaining the keeper (2), a catch (9) movable to a position for locking the fork member (3) on the keeper (2), and a control lever (12) for the catch (9) for unlocking the fork member (3). The lever (12) is connected to an outer or inner opening control (13, 14) and is associated with an electric deactivating circuit comprising switches (25, 26) and an electromechanism so arranged that an attempt to open in an unauthorized manner after the deactivation of the door causes the closure of one of the switches (25, 26) and the supply of current to the electromechanism which automatically releases the lever (12) from the catch (9) and prevents the unlocking of the latch by the catch. In the event of a breakdown of the supply battery, the lever (12) remains coupled to the catch (9) and permits the opening of the door. FIG. 1.

Abstract: This device comprises at least one pair of screw-and-nut elements cooperative with the fixed and movable parts in respect of which elements the screw angle is large enough to ensure that the efficiency of the translation to the rotation is slightly positive, and is provided with means for locking the rotary element of the pair after adjustment of the position of the movable part. This system permits the locking of the movable part in the chosen position by a relatively small force as compared to the forces to which the device is subjected. The device is useful for adjusting a table guide of a woodworking machine, or for adjusting a car seat or the seat of a stool.

Abstract: This device comprises elements for fixing it to slides (6) which are longitudinally movable on fixed slides (10), other elements allowing the mounting of a seat (4) carrying a cushion (3) and a backrest (2), and, on each side of the seat structure, a cam (5) interposed between the slide (6) and the seat (4). There are provided in the cam (5) bearing tracks (7, 8) for the cam (5) on the slide (6) for the adjustment of the cam (5) in height. Jacks (12, 13) control the height of the cam (5) and the attitude adjusting movement of the seat (4) relative to the cam. This device permits the obtainment of the exact required attitude path, is of small overall size and avoids practically all play or vibrations.
