Definitions

  • the present invention relates to the fixing of covering elements on an already fixed covering, integral with a lining structure and relates more particularly to the fixing of covers on seats, in particular of motor vehicles.
  • leather is a material which has a certain stiffness, so that the fitting of leather covers on seats, the surface of which often has re-entrant parts gives rise to problems in making the cover conform to the hollow shapes of the upholstery. 'origin.
  • the invention aims to solve the problems posed by the placement of covers of a material having a certain stiffness by creating a fastening element which, while being of an extremely simple construction, is very easy to apply in all desired points. '' seat upholstery.
  • a fastening element for a covering on a lining covering already fixed to the frame, in particular a seat characterized in that it comprises a head provided with a point, intended to pass through the covering and covering, a foot holding the covering against the covering, said foot extending transversely with respect to the head and being connected to the latter by a flexible flange whose length corresponds approximately to the sum thicknesses of seat upholstery and upholstery.
  • the invention also relates to a device for installing fasteners of the type defined above, characterized in that it comprises a hollow needle intended to pierce the covering and the covering at the desired location and comprising a axial channel whose end close to the tip of the needle is intended to receive the head of the fixing element and is provided with an axial slot which opens at the level of the tip, an extractor slidably mounted in the channel axial of the needle, said extractor being provided with a stop engaged in the axial slot and intended to cooperate with the head and the foot of the fixing element to ensure by relative displacement of the extractor and the needle, the establishment of the fixing element and the withdrawal of the needle and of the means for moving the extractor in the axial channel of the needle.
  • this element mainly comprises a head 1 provided with a point 2 and a heel 3, a foot 4 of generally cylindrical shape whose direction makes a 90 ° angle with the direction of the head 1 and a curved flange 5 of rectangular section and having a flexibility greater than that of the head 1 and the foot 4 of the element.
  • the point 2 and the heel 3 of the head are arranged on either side of the flange 5.
  • This fixing element which can also be called a dart, is produced by molding in one piece from a high-strength plastic material which is sufficiently flexible to prevent its deterioration during installation and to have an appropriate mechanical resistance in order to ensure the assembly of a cover with an underlying coating at appropriate points.
  • the head 1 of the assembly element or dart according to the invention has a cross section in the region of the heel 3 of roughly rectangular shape with a curved side, as shown in the sectional view of Fig.3 and near the tip 2, a roughly circular cross section as shown in the sectional view of Fig.4.
  • the zone of connection of the head with the curved flange 5 constitutes a flat 6 at the end of the head close to the tip 2.
  • a small boss 7 is provided in the connection zone between the head 1 and its tip 2, intended to ensure the maintenance of the fixing element inside a needle of a positioning device as it will be described later.
  • the roughly rectangular section of the heel 3 is obtained using axial flats 8.
  • the free end 9 of the heel 3 has a curved shape making it possible to facilitate the change of orientation of the head 1 during the fitting of the fastening element as will be described hereinafter with reference to FIGS. 8 to 13.
  • the flange 5 has a rectangular cross section, while the head 1 and the foot 4 of the fixing element have roughly cylindrical shapes.
  • the fastening element according to the invention is placed using a hollow needle 10 having an axial channel 11 which opens at the tip 12 of the needle.
  • the fastening element is loaded into the needle by inserting the head 1 of said element into the end of the axial channel 11.
  • the needle is provided with an axial slot 13 which opens out at the point of the toe 12 and whose width roughly corresponds to the distance between the flats 8 of the heel 3 as well as to the width of the flange. 5 connecting the head 1 with the foot 4 of the fixing element.
  • the width of the slot 13 is adapted to allow the heel 3 of the head and the flange 5 of the fastening element to pass.
  • an extractor plunger 14 actuated by means which will be described hereinafter with reference to FIGS. 14 and 15.
  • the extractor 14 is provided with a lateral stop 15 which projects out of the needle through the axial slot 13 of the latter.
  • the loading of a fixing element into the needle is ensured by inserting the head 1 of the fixing element in the end part close to the tip 12 in the direction of the arrow F.
  • the flange 5 of the dart passes through the axial slot 13 of the channel 11 and the foot 4 is located outside the needle 10.
  • the fixing element is held in the needle by the boss 7 provided in the vicinity of the tip 2 thereof and which is slightly compressed during loading of the fixing element.
  • the driving-in movement of the needle 10 is stopped when the foot 4 of the fixing element abuts against the surface of the cover H to be fixed.
  • the fixing element is then in the position shown in Fig. 8.
  • the tilting of the head 1 occurs beyond the thickness of the covering R and of the cover to be fixed, inside of the filling foam M.
  • the extractor pusher 14 continuing to move towards the surface of the cover H, arrives in a position such that its stop 15 comes into contact with the foot 4 of the fastening element.
  • Figs. 14 and 15 there is shown a device for placing or installing fasteners or darts according to the invention, using a hollow needle.
  • the tubular needle 10 comprises, as indicated above with reference to FIGS. 7 to 13, an axial channel 11 and a point 12 intended to pierce a hole in the original coating and in the cover as described with reference to FIG. 8 .
  • the extractor pusher 14 In the axial channel 11, is mounted displaceable in translation, the extractor pusher 14 provided with its stop 15 protruding out of the axial channel 11 through the slot 13 formed at the free end of the needle.
  • the extractor 14 is extended in the axial channel 11 by a rod 20 which carries at its end opposite to the extractor 14, an operating button 21. At its end situated opposite the button 21, the needle carries a handle 22 Between one of the branches of the handle 22 and the operating button 21 is a knee lever 23 whose levers 24 and 25 are articulated respectively on the handle 22 and on the button 21, while the point of articulation between the two levers 24 and 25 includes a button 26 for locking and unlocking the toggle.
  • a spring 27 for returning the toggle joint in the locked position surrounds the articulation of the lever 24 on the handle 22 secured to the needle 10.
  • Fig.14 the device is shown in the rest position in which the extractor pusher 14 is retracted inside the needle 10 and thus releases a space 28 for receiving a fixing element.
  • the toggle switch 24.25 is in the locked position and immobilizes the extractor plunger 14 relative to the needle 10.
  • the closing movement in the hand between the handle 22 and the operating button 21 makes it possible to continuously exert pressure on the assembly and consequently on the heel 3 of the head 1 of the fastening element. This has the effect of causing the progressive withdrawal of the needle as already explained with reference to Figs. 8 to 13 and the positioning of the fixing element by changing the orientation of the head 1 which is placed behind the face of the initial coating R opposite the cover H.
  • the device for fitting fixing elements or darts which has just been described with reference to FIGS. 14 and 15, is of a particularly simple design and makes it possible to ensure the assembly of a cover with a covering a seat by laying "blind" fasteners according to the invention.
