  • Patent number: 8225551
    Abstract: A device that includes at least one slider joined to a window which slides along the rail defining the trajectory for the window. The trajectory is defined by a departure angle formed by the vertical and initial upper curvature of the rail which is ±45° and the curvature radius of the aforementioned trajectory which is about 0 to 500 mm. The device includes a means of adjusting the position of the device with regard to a door including an upper pivoting axle on the rail which allows the device to tilt to fit it in the door with two lower transversal screws for lateral adjustment, and one screw on the slider for adjusting the window with regard to the rail and the slider.

  • Patent number: 8215200
    Abstract: A low sliding load intermediate shaft comprising a female member slightly receiving a male member and a series of metal strips, such as three, fitted therebetween. The metal strips are retained in position since they are received into the cavities of a fastening cage clamped to the outer surface of the male member. They allow longitudinal movement friction of both members eliminating clearance and radial play with a total effectiveness in torque transmission at any time.

  • Patent number: 8187109
    Abstract: An intermediate shaft to adjust the height of a steering wheel to match a driver's measurements, to absorb vibrations which may be generated by the wheels and suspension up to the steering wheel, and to act as a safety measure to collapse in the event of an accident. The shaft utilizes corresponding screw/nut mechanisms comprising a nut rigidly connected to the intermediate shaft on one of the flat surfaces of a female shaft and a screw which turns to tighten a male shaft via an adjustment strip to allow adjustment of the sliding load and the torsional rigidity and hysteresis of the sliding intermediate shaft.

  • Patent number: 7604428
    Abstract: A mounting assembly for a universal joint that includes a yoke with wings between which a driving shaft is provided. The wings have respective holes. A bolt having a head and a stem is transversely to the wings. A sleeve receives the stem of the bolt so that, in an assembled position, the sleeve exerts a pressure on a surface of the driving shaft preventing its axial movement, wherein the stem has at least a first, threaded end portion, a second, non-threaded adjacent portion, and a third portion. The diameter of the second portion is slightly larger than an inner diameter of the sleeve. The third portion has a diameter slightly larger than the second portion. When the bolt is inserted into the sleeve, the sleeve expands resulting in an increase of its outer dimensions against the surface of the driving shaft blocking it axially in position as it is pressed against the yoke. The third portion of the bolt is received in one of the holes, thereby seating the bolt with respect to the yoke.

  • Publication number: 20020137570
    Abstract: There are provided two shafts which can be faced in different directions one of which ends including a first fork with a crosspiece joining it with a second fork. The second forks are mechanically joined to each other by means of an axial displacement device comprising a first bearing plate that is formed integrally to the second fork of one of the shafts, an intermediate plate and a second bearing plate. The first bearing plate is provided with columns formed integrally thereto and to the second bearing plate. The intermediate plate comprises through bores that receive said columns (19, 20, 21), and a column formed integrally thereto and to the second fork of the other shaft. The relative clearance between said first bearing plate and the intermediate plate defines the possible displacement between the forks of the respective shafts.
