    l0 type of fault locking is avoided. This is especially important when the buckle is of the hook lock type, whereby e.g. the clamping part connected to the remoglan can hook in and get stuck in a part of the baby carrier. The user may then be misled into believing that he has hooked in and locked the buckle correctly. This is due to the fact that the buckle may not be seen by the user.
    Summary of the invention An object of the invention is to provide a safety buckle in which the two buckle parts always lock to each other even when the operating key is actuated / pressed to open the safety buckle.
    A further object of the invention is to provide a safety buckle in which, when locking the two buckle parts to each other, at least one acoustic indication arises.
    This is achieved according to the invention by providing a safety buckle comprising a first buckle part comprising an at least partially closed space with an opening, and a second buckle part comprising a body, a guide tongue arranged at the body and a control key, and it is characteristic of the invention that when locking of the safety buckle, the guide tongue is arranged to be accommodated in the at least partially closed space, that a resilient latch, which is arranged in the at least partially closed space, is arranged to lock against a locking means arranged in the control key, i) that the latch is arranged to provide a first locking with the locking means even when the control key is actuated, and the latch is arranged to effect a second locking with the locking means, when the operating key is no longer actuated, or ii) that the latch is arranged to effect locking with the locking means, when the operating key is not actuated, and that the pawl is arranged to be released from engagement with the locking member vi d in case i) renewed influence of the control key or in case ii) influence of the control key.
    Preferred embodiments are set out in the dependent claims.
    Short. The invention is described in more detail below with reference to the accompanying drawings, in which Fig. 1 is a schematic sectional side view of a first embodiment of a divisible safety chip according to the invention, wherein a first clamping part is attached to a schematically shown front piece of a sling and a second clamping part is attached to a schematically shown belt loop, Fig. 2 is a schematic view obliquely from above of the first clamping part, Fig. 3a is a schematic view from behind of the second clamping part with no control key pressed, Fig. 3b is a view corresponding to that in Fig. 3a but with the control key pressed in.

    Description of Preferred Embodiments The following description describes a first embodiment of a safety chip according to the invention for coupling a belt loop with a front piece to a child carrier harness. In the second embodiment of the security chip according to the invention, it can be used for interconnecting e.g. a strip of ram breathes side by side to produce a closed loop. However, it is obvious to the person skilled in the art that the safety chip according to the invention can be used for interconnecting other parts than those mentioned above.
    As can be seen from Figs. 1 and 2, a first embodiment of a divisible security chip 1 according to the invention comprises two interconnectable chip parts, a first chip part 10 and a second chip part 50. The first chip part 10 is fixed to a schematically shown front piece 3 of a child carrier harness (not shown) , and the second chip part 50 years fixed to a schematically shown belt loop 2 for said child carrier harness.
    The first chip part 10 comprises a groove 17 resiliently suspended in both height and laterally which is fixedly connected to the first chip part and is intended, in the locked position of the security chip, to come into engagement with a locking member of the second chip part 50. The first chip part 10 forms a housing comprising a fastening plate 11 and a bracket 12 arranged on the fastening plate. The bracket 12 comprises two side walls 13a, 13b, a breath wall 13c and a bracket part 14 for forming an at least partially closed space 15 inside the housing with an opening 16. In the at least partially closed space 15 years the resilient ratchet 17 arranged. The end of the groove hook 17 opposite the hook itself 18 is preferably fixed to the mounting plate 11.
    The hook 18 can be provided with a tongue 18a (Fig. 8) intended to run in a projection 19 in the mounting plate 11. This tongue is arranged to limit the movement of the pawl in the side and height.
    Furthermore, the mounting plate 11 is provided with a slot 21 through which e.g. a strap or the like is intended to be threaded for fastening the same to the first clamping part 10.
    The fastening plate 11 can also be provided with a sewing edge 30 for fastening the first clamping part to a base.
    From the first embodiment of the second clamping part 50 shown in Figs. 3a-5, it appears that it comprises a substantially cup-shaped body 51 with a main part 52 and two side walls 53a, 53b, an end wall 53c and an open portion 54, a guide tongue 55 is arranged to extend from the end wall 53c towards the open portion 54. A spring-biased control key 56 for actuating the catch 17 for opening the safety buckle is arranged in connection with the end wall 53c and has the shape of an elongate rod with recesses 61, 61a (Fig. 7). ).
    The safety buckle is designed in such a way that when the control key is pressed, it is possible to open it.
    In the first embodiment of the clamping part 50, the guide tongue 55 is placed substantially parallel to the main part 52. Between at least a part of the guide tongue 55 and the main part 52 there is a space 57, in which at least a front part 22 (Fig. 2) of the first clamping part 10 bracket 14 is arranged to be accommodated in the locked position of the safety buckle.
    Seen as in Fig. 4, the underside of the guide tongue 55 is preferably placed level with the end edges of the respective side wall 53a, 53b, which prevents the guide tongue from accidentally hooking into any part not intended for this purpose.
    Preferably, a ridge 58 is arranged along substantially the entire length of the guide tongue 55 and directed towards the main part 52. A portion 58a of the ridge 58 projects in front of a front end 55a of the guide tongue. The portion 58a of the ridge is intended to provide an initial engagement with the yoke portion 14 of the first clamping member when locking the safety buckle. The bracket of the first clamping part, which has contact with the ridge 58, is preferably provided with a recess 23 complementary thereto (Fig. 2).
    Furthermore, as can be seen from Fig. 1, in particular the inside of the main part 52 of the second clamping part 50 is arranged to abut against at least the front part 22 of the stirrup part 14 of the first clamping part 10.
    During insertion of the guide tongue 55 into the opening 16, the side walls 53a, 53b of the cup-shaped body 51 and the side walls 13a, 13b of the yoke 12 are intended to cooperate to provide suitable control between the ram clamping parts and to have a certain play between them. The side walls 53a, 53b are intended to be placed over the side walls 13a, 13b. This facilitates the insertion of the guide tongue 55 into the opening 16.
    In addition, by making the side edges 20 of the opening 16 of the yoke 12 oblique and making the front end 55a of the guide tongue 55 arcuate, the guide tongue can only be inserted into the opening at a relatively small angle. In a preferred embodiment, the angle between the guide tongue 55 and the main direction of the opening 16 amounts to about 15 °. This means that in the case of application angles between the guide tongue 55 and the opening 16 outside the above-mentioned angular range, the guide tongue will always slide past the opening, i.e. the safety buckle does not allow any semi-locked position to occur between the first and second buckle members 10,50, but only when the guide tongue 55 and the opening 16 in the second buckle member 50 have been placed at right angular intervals relative to each other and exposed to an external force, which presses the same against each other, which the two clamping parts 10,50 can lock to each other.
    The operating key 56 is preferably designed as a rod with two different deep recesses 61, 61a arranged next to each other, see Fig. 7. During the insertion of the guide tongue 55 into the opening 16, the hook 18 of the pawl 17 is arranged to slide abutting and resiliently biased against a first recess 60. in the guide tongue 55 all the way to the same bottom in the housing, in which position the hook 18 is arranged to be resiliently inserted in the recess 61 in the operating key and lock against a locking means 62, which in the embodiments shown is made in the form of a locking surface 62 and which forms part of the guide tongue 55. At the resilient insertion of the hook 18 in the recess 61, an acoustic indication arises, e.g. a clicking sound, which confirms that the safety buckle has locked at the steering wheel set. In this position, the hook is enclosed between a stop surface 63 and a delimiting surface 64 located on each side of the recess 61.
    When unlocking the safety buckle, the control key 56 is actuated by depressing it, ie. it is displaced laterally in the direction of the arrow as shown in Fig. 3b, the abutment surface 63, which may be a wall of the recess 61, being arranged to displace laterally, seen as on the left in Figs. 3a and 3b, the catch 18 of the ratchet 17 until it reaches a second, deeper relative to the first recess 60, deeper recesses 70 in the guide tongue 55, the second recess having no locking surface. As a result, the hook is released from and no longer abuts against the locking surface 62. In this laterally offset position of the catch, the two clamping parts can be moved apart. Preferably, a bottom surface of the second recess is sloping so that its deepest part is located in line with the locking surface 62 to gradually become shallower towards the leading edge of the guide tongue 55.
    In a particularly preferred embodiment, in the depressed position of the control key 56, as shown in Fig. 3b, a slightly shallower recess 61a than the recess 61 is arranged in the bar of the control key and arranged to be in line with the pawl. This shallower recess enables that, in the complete position of the guide tongue 55 inserted into the housing, the hook 18 of the ratchet 17 will be resiliently inserted in the recess 61a and lock against the locking surface 62, however with a slightly less locking surface of the hook, i.e. a first locking is obtained, whereby even in this position an acoustic indication has arisen which confirms that the safety buckle has locked. When the control key is then released in this position, it returns to its unaffected position, as seen on the right in Figs. 3a and 3b, and the hook 18 will be completely inserted into the recess 61, whereby a second locking is effected and a further acoustic indication arises. Ie. in case the control key is intentionally or unintentionally pressed, when locking the two clamping parts to each other, two acoustic indications will occur, a first when the hook 18 is resiliently inserted into the shallower recess 61a and a second when the hook resiliently is inserted into the recess 61 when moving the control key sideways. In both cases, the hook 18 locks against the same locking surface 62.
    Furthermore, the body 51 of the second clamping part 50 is provided with a slot 65 through which e.g. a strap or equivalent is intended to be threaded.
    As can be seen from Fig. 1, in the locked position of the safety buckle, the upper side of the yoke part 14 of the first buckle part 10 with associated side edges 13a, 13b is arranged to abut tightly against the underside of the main part 52 of the second buckle part 50 with associated side edges 53a, 53b. By making the safety buckle in this way, it is achieved that, when locking the safety buckle, no undesired material, such as loose fabric, etc., can get caught between the ram buckle parts.
    Furthermore, the first embodiment of the safety buckle shown in Figs. 1-5 can be designed to provide e.g. a right and left buckle, ie. a form of key which does not allow the first clamping part of the left buckle to be inserted into and locked at the second clamping part of the right buckle and vice versa. For this purpose, a projecting lug 40 (Fig. 2) can be arranged on the inside of the stirrup 12 facing the space 15 and arranged to fit in and cooperate with a complementary recess 41 (Fig. 4) arranged in the part of the guide tongue 55 which is directed towards the space 57.
    In the second embodiment of a safety buckle 1 'according to the invention shown in Fig. 6, the same comprises two interconnectable clamping parts, a first clamping part 10' and a second clamping part 50 '. The first clamping part 10 'may be designed identical to the first clamping part 10 in the first embodiment.
    What distinguishes the second clamping part 50 'from the second clamping part 50 is that the guide tongue 55' has been rotated 180 ° so that instead of lying below the main part 52 it projects from the end wall 53c '.
    Locking of the safety buckle takes place in the same way in the two embodiments and the reading between the two buckle parts is always achieved regardless of whether the control key 56 'is affected or not and one or two acoustic indications arise depending on the position of the control key 56'.
    Because the guide tongue 55 'projects, the side walls 53a, 53b in the first embodiment have no guiding function, whereby this part of the clamping part 50' can be designed in a closed and not ergonomically suitable manner (not shown). This means that the entire control during the locking of the two clamping parts to each other is effected by the guide tongue 55 'when it is inserted into the opening 16' in the housing. Also in this embodiment the side edges of the wall 53c 'preferably have a complementary shape with the' side edges' of the opening 16.
    To improve the locking between the latch 17 and the locking member 62, at least in an initial locking position between the first 10 and the second clamping part 50, in a preferred embodiment, as shown in Fig. 8, the latch 18 of the latch 17 is provided with the lug 80 which is directed towards and arranged to cooperate with a complementary lug 81 of the locking member 62, which lug 81 is directed towards the hook.
