  • primary lock which is intended to lock the male part when the latter is inserted into the female part and to allow its release or disengagement from such a locked position
  • the primary lock being designed under the form of a lever which can pivot around an axis parallel to the plane of the male part and arranged perpendicular to the direction of movement of the male part in the female part, the primary lock having one or more projecting parts serving, in a first pivot position (locking position), to cooperate with an opening or corresponding housings provided on the male part and lock the male part to female part, and serving, in a second pivoting position (unlocking position), to release the male part, the primary lock being subjected to the action of a spring acting in the release direction and having a pointer which cooperates with a locking means which can move along the pointer and hereinafter called “secondary lock", intended to prevent the primary lock from pivoting in the release direction for a position called position of locking of the secondary lock, while the secondary lock allows the primary lock to pivot in a second position called the
  • the primary lock has a lever arm comprising at its outer end a first pair of parts in downward protrusion and a second pair of upward protruding portions.
  • the first pair of projecting parts comes into corresponding openings or housings provided in the male part of the loop.
  • the secondary lock rod is provided to contact the upper end surfaces of the protrusions of the second pair of protrusions to prevent the primary lock lever from moving up.
  • the compression spring tending to move the rod to bring it into the locking position extends between this rod and a U-shaped part of the primary lock.
  • the spring tending to move the operating device in its inactive position is provided in a bore of the operating device and extends between the bottom of this bore and the rod of the secondary lock.
  • the primary lock comprises a lever with two arms, that is to say a lever extending on both sides of said pivot axis, the part of the lever directed towards the insertion opening supporting the part projecting which cooperates with the male part, and the part of said lever directed inwards supporting the guide dog cooperating with the secondary latch, said guide dog being delimited by a surface which is directed in the same direction as the projecting part, the internal end of the spring which loads the operating device as well as the internal ends of the spring or springs which load the secondary lock being carried by a common piece in the shape of a stirrup mounted in the internal portion of the female part .
  • the loop according to the present invention occupies a minimum of space in the direction perpendicular to the plane of the male part of the loop.
  • the manufacture of the loop is also simplified by the fact that the stirrup-shaped part and the springs carried by this part can be assembled in block on the female part of the loop.
  • the stirrup-shaped part is also provided for carrying the spring of the loop ejector.
  • the loop which is illustrated in FIGS. 1 and 2 comprises an insertion part or male part in the form of a tongue, indicated as a whole by the reference 1, and a receiving part or female part in the form of a sleeve, indicated as a whole. by the reference 2.
  • the male part 1 has a loop-shaped portion 3 with an elongated opening 4 through which a strip forming part of a seat belt is provided to pass.
  • the female part 2 has a frame 5 which is produced from a piece of sheet steel folded in the shape of a U-shaped trough. The side walls of the trough are indicated in 5a and its bottom in 5b.
  • the mounting part 6 has an end part in the form of a loop delimiting an opening 8 for the passage of a bolt allowing the mounting of the female part 2 on the unrepresented body of a vehicle or on any other appropriate part of the vehicle in question. It is not beyond the scope of the invention to fix the female part to the vehicle in any other way than directly by means of a sheet metal mounting part. It is obviously also possible to suspend the female part at one end of a strip. It can also be imagined to mount the female part on the vehicle via a flexible bar or the like.
  • a pivot axis 9 for a locking means 10 extends parallel to the bottom 5b of the frame and perpendicular to the direction of insertion of the male part into the female part, this direction being directed to the right in the drawing.
  • the locking means 10, articulated on the pivot axis 9, is intended to maintain the male part 1 in a position for which it is locked to the female part 2, which is the position illustrated in FIGS. 1 and 2.
  • the locking means 10, which hereinafter is called “primary lock” is produced from a piece of sheet steel folded into a U, as can be seen in FIG. 2, and its lateral branches 10a have the form of a lever with two arms which are crossed by the pivot axis 9 which thus constitutes the pivot center of the lever.
  • the middle part 10b of the primary lock according to FIG.
  • the elongated hole 14 delimits a guide for a part 15a forming a rod projecting downwards from the body 15 of an ejector sliding on the top of the bottom 5b, the body of the ejector further comprising a rod 15b surrounded by one of the ends of a pressure spring 16.
  • the other end of the spring 16 bears against a finger 17a projecting downwards from a piece 17 in the shape of a stirrup which, at its upper part, extends between the two side walls 5a of the frame and which, with projections 17b directed in the opposite direction, is maintained, in corresponding housings open upwards at the edge of the side wall 5a.
  • the finger 17a also has a rod 17a 'projecting in the end part of the spring.
  • An additional pivot axis parallel to the axis 9 is indicated at 18 and passes through the wall 5a of the housing.
  • the axis 18 is called in the following "secondary lock" because of its locking function in cooperation with a retaining dog 19 directed downwards from the part 10a 'of the arm projecting inwards from each of the side parts of the primary lock.
  • the arm part 10a ′ further comprises a guide face 20 directed downwards and which cooperates with a cam 33 of the ejector, which moves against the thrust of the spring 16 to the right of the drawing, this is that is, moving away from the position shown.
  • the secondary lock 18 is tightened by a sleeve-shaped holding member 21 which has two parallel guide rods 21a which extend in corresponding bores 17c in the rear part of the stirrup-shaped part 17.
  • Two pressure springs 22 extend between the stirrup-shaped part 17 and the retaining member 21, and these springs each surround its guide rod 21a and tend to move the secondary lock and bring it into the position illustrated in which it bears against the finger 17a projecting downwards from the part 17 in the shape of a stirrup.
  • the possible movement of the secondary lock is so long that, by opposing the thrust of the springs 22, it can be moved and released from the edges of the retaining dog 19, so that the primary lock can pivot in the direction clockwise according to fig.
  • the part 17 in the shape of a stirrup also has a projecting finger 17d which is surrounded by a pressure spring 32, one end of which bears against a pointer 23 of part 17 in the shape of a stirrup, while the other. end bears against a guide dog 24 of an operating element 25 which has lateral parts in 25a fork shape arranged outside the side pieces 5a of the frame and parallel to these pieces.
  • the pivot axis 9 passes through oblong slots 26 of the lateral part 25a of the operating element 25.
  • the lateral parts 25a of the operating element 25 have, near their free end portions (on the right on the Fig.
  • the pivot axis 9 is placed at a certain distance and above the end of the male part, which means that when the primary lock 10 is released and the body 15 of the ejector under the pressure of the spring tends to eject the male part, there is a pivoting by force of the primary lock in a clockwise direction according to FIG. 1, that is to say out of its position of engagement with the opening 12 of the end of the male part.
  • the male part 1 instead of its central opening 12, can obviously have housings in these two lateral edges. In this case, obviously, the projecting central part 11 of the primary lock must be replaced by two projections provided on the sides and cooperating with the lateral housings of the male part.
  • the primary lock is then held in its free position by the retaining dog of the body 15 of the ejector striking the rear face of its intermediate piece 10b.
  • the retaining dog of the male part comes into contact with the body 15 of the ejector which, during the continuous movement towards the interior of the male part against the thrust of the spring 16 due to the cooperation of the cam 33 and the sliding surface 20 of the primary lock, causes the latter to force to pivot in the anti-clockwise direction according to FIG.
  • Figs 3 and 4 schematically represent an embodiment which finds an application in connection with the male parts having the lateral housings 29 mentioned previously by way of example in place of the central opening 12 provided on the male part according to the previous example.
  • This embodiment means that the primary lock 10 has, instead, two projecting parts 11 in its sides, these projecting parts cooperating with edges 29a of the retaining dog of the lateral housings of the male part.
  • the protruding parts 11 also have an oblique edge portion 11a which means that the lifting height necessary for the primary lock to allow it to be released is reduced compared to that of the previous example.
  • Figs 5 and 6 there is shown an embodiment which corresponds substantially to the embodiment shown in Figs 3 and 4 but which has the difference that the protruding part 11 for engaging the primary latch does not extend downwards. through the bottom 5b of the frame.
  • the embodiment shown in Figs 7 and 8, as was the case with the embodiments shown in Figs 3 to 6, is intended to be used in connection with male parts having housings in their lateral edge.
  • the primary lock differs from those previously described with respect to the intermediate part, which is missing in this embodiment, because the branch-shaped parts are replaced by separate arms 10a which are kept at a distance from one the other by means of a spacer sleeve 30 extending between them.
  • the spacer sleeve 30 can suitably be rigidly connected to the locking pieces 10a so as to coordinate their movement.
  • the cam of the body of the ejector as well as the corresponding corner face of the primary lock according to the previous embodiment have been replaced by a projection 31 on the primary lock which is supported against the rear face of the body 15 of the ejector.
  • the primary lock On insertion of the male part, the primary lock is thus forced into the engagement position by cooperation between the body of the ejector and the projection 31.
  • the body of the ejector can also preventing the primary lock from accidentally occupying a locking position when the male part is not inserted into the female part.
