    PCT No. PCT/SE81/00178 Sec. 371 Date Feb. 10, 1982 Sec. 102(e) Date Feb. 10, 1982 PCT Filed Jun. 15, 1981 PCT Pub. No. WO81/03603 PCT Pub. Date Dec. 24, 1981.A safety belt buckle fitted with belt straps and two interlocking parts. These are designed for releasably connecting the belt strap. One interlocking part consists of a locked part and the other interlocking part consists of a locking part. The latter is fitted with a locking member pivoted in the locking part and able to be reset between the position releasing and the position locking the locked part. The locking member is spring loaded so as to attempt to pivot to its releasing position. A detent member is able to be reset between a detent position in which the locking member is prevented from being reset from its locking position and a releasing position in which the locking member is permitted to pivot to its releasing position. An ejector is arranged so as to eject the locked part by the action of a spring when the locking member is rest to the locking position. A link connects the detent member to the ejector. The link is loaded by a spring which attempts to move the ejector to its outer position. When the ejector is pushed in by means of the locked part it brings with it the detent member away from its releasing position. By the action of the spring the detent member is moved to the locking position. When moved from its locking position the detent member is moved to its releasing position and the ejector is moved to its outer position by the action of the spring.

    This invention relates to a jc rescue technique. The known safety belt buckle, comprising a locking part and a locking part consisting of a locking element disposed in the housing, is hinged to move between locking positions and unlocking with the locking part, a spring for securing the locking element holding the locking elements of the lockable element and the ejector of the lockable part with the spring 1; The disadvantage of the known buckle is that in it the locking element forms an edge, which can be hooked by the locking element partial engagement, resulting in partial engagement. . The purpose of the invention is to improve the reliability of the work. This goal is achieved by the fact that the seat belt buckle contains a locking part and a locking part consisting of hinged elements installed in the case of the locking element for moving between the locking position and unlocking with the locking part of the spring to enable the locking element to move, the retaining element for holding lockable element and ejector; a lockable part with a spring; has a movable lever for kinematically coupling the holding element to the ejector; and its spring is installed between the locking element and with the lever lever. In this case, the retaining element is made in the form of a rod mounted on one of the ends of the connecting lever, and in the case of the locking part angular cuts are made to accommodate the ends of the rod, and the connecting lever is placed in the ejector with the possibility of turning the other connecting lever when locking and disengaging from the lockable part, and the ejector spring contacts the connecting lever in the zone located between its ends. Figure 1 shows a buckle in a closed position, a general view of $ in the fig, the same in an open position, on a fig. 3 - the same, in a disassembled state, and in figure 4 - a longitudinal section along the center of the buckle. in the closed position; figure 5 - the same, in the open position. The buckle consists of two interconnecting parts of the locking and locking parts, respectively, locking tongue 1 and locking device 2. Locking tongue 1 is attached to the belt loop and is provided, for example, with a slit (not shown) into which the tongue is passed and which guides lmku on the way between the lap and breastplate, as in the case of the so-called three-point belts. The locking device is mounted on a fixed part, for example, a car, in particular, on the floor of the body or on the convex part of the floor above the cardan shaft, by means of a pulling element 3 made in the form of a wire loop. The locking device 2 consists of a body 4, made, for example, of metal, and has a box-shaped cross-section, i.e. the base 5 and two identical side walls 6. The locking device 2 is closed by means of a clip 7 made of an easily formed material, such as plastic and having an inlet 8 for the locking tongue 1. The locking device 2 comprises a locking element 9, which in its front part has two downward locking hooks 10, and in the rear part there are two side-facing support lugs 11 designed to interact with the rear-facing supporting surfaces 12 of the notches 13, one at a time in each side wall 6. The locking element, in addition, has in its front part a tongue 14, forming a supporting element for the compression spring 15, the purpose of which is to hold the trigger element 16 of the buckle in the outer Assumption. The locking element 9 also has a central bushing 17, through which the compression spring 18 passes. In the cut-out zone 17, there is a tongue-like element 19 for holding the compression spring 18. In its rear part, the locking element 9 also has a circular opening 20 for accommodating a load absorption pin 21 secured in the housing 4. It is preferable to perform the circular opening 20 with a diameter. exceeding the diameter of the pin 21, and positioned in the release position so that the surface of the hole 20 and the pin 21 has a certain gap. The locking element 9 is held on a flat surface 22 of the washer 23, covering the pin 2. In the engaged position, two locking hooks 10 of the locking element, descending, go on each side of the neck 2A of the locking tongue entering the notch 25 in the locking element. The locking hooks 10, moving in a downward direction, enter the ends 26, exaggerated at the base, which have front, rearward-facing devices that absorb the load restricting surfaces 27. The locking tongue is provided with a head 28, which has rear-facing restrictive surfaces 29 interacting with the picking hooks 10 of the pick-up element 9. The head of the locking element 9 has a rounded end 30 dp of interaction with the pusher 31 moving in the locking device in the direction of movement language 1 and by means of a spring 18 compressed pressed in the direction of the entrance of the locking language. The ejector is made of, for example, an easily formaable material, in particular of plastic, and is capable of moving between the outer position, which it occupies when the locking tongue is disconnected from the pick-up device, and the inner position occupied by it under the action of the locking tongue, overcoming the resistance of the compression spring 15 . The ejector 31 has a notch 32, the shape of which corresponds to the front end 30 of the locking tongue 1 and which is adapted to accommodate said end. The fuse 33 in the ejector 31 prevents the accidental entry of the locking tongue into the locking device. Fucked up device. also includes a retaining element, which is made in the form of a rod 34. The retaining rod passes through Two guides of the notch 35 - each wall 6 has one notch and is able to move along a path defined by the shape of the aforementioned
    call. Each notch has one part 36 directed parallel to the path of the lock tongue along the base 1
    In this case, the axis of rotation is determined by the angular cuts 35. Between the two axes of rotation of the link 42 there is a protrusion 24 5 of the housing 4. The continuation of part 37, therefore, intersects the path of movement of the locking tongue or the continuation of this path. Thus, the holes 35 have an angular configuration. The holding rod 34 is controlled by the trigger element 16, which is accessible from the outside through an opening (not shown) in the lid 7. The trigger element can be moved in the longitudinal direction of the buckle, i.e. in the direction of the entrance of the locking element 1, and has two side sections 38, abutting its abutting surfaces 39 into the retaining rod 34 when pressing the shutter element 16, the latter being spring-loaded with a compression spring 15 held by the locking element 9, and, therefore, supplied with force return, moving it to the outer position after pressing the trigger element. The trigger element 16 has two limiters of the final position, consisting of fingers, moving the cutouts 41 in both side walls 6 of the housing 4. End position limiters also contribute to the stability of the trigger element during its movements. The locking mechanism of the buckle has a link 42, one end 43 of which is connected to the holding rod and the other 44 to the ejector 31. The link 42 has a groove 45 at one end, which holds the holding rod in the action of a crimp. The lower end 44 of the link 42 is designed as support studs 46. The link is designed so that it can move downward through the notch 47 in the ejector 31 and insert its lateral support spikes 46 forming the lower axis of rotation into the groove 48 in the ejector 31 moreover, the part of this groove is open facing the rear of the device. With this design, the link 42 forms a pivotally rotating element that rotates around two axes of rotation along one axis at each end — the upper axis of rotation forming a holding rod 34. The lower axis. The stage is moved straight forward and backward along the entrance path of the locking pin 1, and the top 49 moves, the front attachment point of the compression spring 18, the opposite end of which is attached to the tongue protrusion 19 of the locking element. Thus, the compression spring 18 exerts a compressive force on the link used to move the holding member FOR, and the same ejector 31, which has guide lugs 50 with a rear restrictive surface 51. The proposed buckling works as follows. The two interconnecting parts of the buckle are disconnected when the locking tongue 2 is removed from the locking device 2 and the locking device is in the tripping position. It occupies this position when the belt is in the inoperative position and is disengaged, and the belt belt is pulled inward by means of the winding device (Sne is shown). The belt may be of the so-called static type, without a winding device. When the locking device 2 is in the uncoupling state, the holding rod 34 takes over the unlocking position, i.e. is located in the area of the outer end of the part 37 of guide vanes 35, which is directed transversely to the path of the locking tongue 1. The trapped position of the holding rod 34 ensures that the relatively rigid link 42 and the ejector insert 31 are maintained at a predetermined distance , in contact with the restrictive surfaces 27 of the notches 26. The ejector in the notches 26 is moved by the guides 50 on its base and has certain end positions defined by Independent user 27 and the rear limiter 51 GOVERNMENTAL surfaces. These positions he occupies under the action of a compression spring 18, which at the same time creates a force holding the locking element 9 in the uncoupling position, i.e. in a deflected upward position. When the locking tongue 1 is inserted into the inlet opening passing through the base 5 of the housing 4, and the front cone 30 of the head 28 enters the outlet 32 in the ejector 31, the latter is still given inside the locking device 2 along the entrance path, overcome 26 spring resistance 15 compression. The lower axis of rotation 46, moving straight along the input path, causes the link 42 to rotate around said axis of rotation 46, as well as around the upper axis of rotation, i.e. the holding rod 34. Due to the constant state between the two axes of rotation, the holding rod 34 is pulled down along part 37 of the cutout 35 and t is not at the same time the locking element 9, and when the locking tongue 1 goes so deep into the locking device that takes the lock position, i.e. When restrictive, the back facing surface 29 of the locking tongue bypasses the locking position of the locking hooks 10 of the locking element, the locking element deflects backward so that its locking hooks 10 enter the locking language's input path. When the retaining rod 34 is retracted backward, through the link 42, the spring force 18 is pressed in the left direction. As a result, when the retaining rod 34 is retracted down to a position opposite to the longitudinal section 36 of the tube 35, the retaining rod in this section of the rod moves forward as the link 42 rotates around its lower axis 46, moving to the locking position of the buckle . With this movement, the ejector 31 and the locking tongue 1 are able to pass under the action of the compression spring 15 a certain distance in the opposite direction, i.e. in the outward direction so that the rearward facing surfaces 29 of the locking tongue 1 come into contact with the locking hooks 10. The straightening will result in a position in which it is able to transfer the necessary load from the belt through the locking tongue 3. This is achieved by means of the rearward-facing limiting surfaces 29 of the locking tongue and the locking hooks 10 of the locking element 9, as well as by means of the surfaces of the locking element 20 in the locking element and the pin 21, from which manual ultrasonic inspection transmitted zakreplyyuschemu element 3. Its role in the absorption of loads and plays the housing 4 where the load is sensed by a pin 21 attached, for example a rivet.
    to the housing base 5, as well as locking hooks 10 of the locking element 9, pulled forward under the action of the load, before coming into contact with restrictive surfaces 27, which prevents straightening of the locking hooks. Elastic loading by means of a compression spring 15 provides for a certain gap between the locking hooks 10 and restrictive surfaces 26 under no load conditions, as well as the clearance of the pin 21, which allows a satisfactory and easily controlled mechanism to be obtained to eliminate the need to meet extremely stringent requirements, imposed on tolerances.
    In order to detach the locking tongue 1 from the locking device, the press is pressed, for example, with the thumb on the trigger element 16, overcoming the resistance of the compression spring 15, thereby inserting the Guide surfaces 39 of the trigger element 39 into contact with the ends of the holding rod 34 moving along the longitudinal section 36 of the cutout 35 and also the linking element 42 and possibly the ejector 31, thus overcoming the resistance of the compression spring 18. Under the action of the force of the spring 18, squeezing the locking element 9, the latter constantly strives to turn in the upward direction in order to take the release position. This rotation in the upward direction is possible after the retaining rod takes a position against the transverse section 37 of the notch 35. With the help of properly adjusted arms of the pair, such a ratio of forces ensures that the locking element 9 acts on the retaining rod with a force that moves this rod upwards transverse section 37 of the bluff 35, while the lower end 44 of the link 42 is moved forward by the force of the spring 18 of compression, advancing the pusher 31 in the direction inward of the mouth oystva on the input path. Before that, the locking hooks 10 of the locking element
    9 out of the entrance path, freeing the ejector shut-off, the ejection is effected by moving the ejector 31 to its forward end position. After pressing the trigger element 16, it is immediately returned to the outer end position by means of a compression spring 15.
    The invention is not limited to the example of its implementation described above and shown in the drawings, it can be changed within the scope of the claims. For example, the cutout 35 may not be an angular configuration, but inclined with respect to the inlet path. Compression spring 18 for the trigger element 16 may, for example, not be attached to the locking element, but to the 7 "part of the clamp. In some cases, movement is possible using a flexible or hinge link. In addition, the locking tongue can be made in the form of a tongue with a hole running in the center, instead of the arrow-shaped tongue, two locking hooks
    10 locking element 9 can be replaced with a single locking part, symmetrically located in the device ..
    The proposed buckle design provides non-disengagement of belts in case of an accident, which increases safety during vehicle operation.
