    Automatic wind-up roller for a safety belt with means to block the belt roller in case of danger. The wind-up roller has an automatic release mechanism which is activated when the vehicle exceeds a predetermined acceleration or deceleration. The automatic release mechanism when activated in turn activates a control element, wherein at least two locking pawls, preferably arranged at opposite sides of the belt shaft, are caused to interact with locking tooth means to block the belt roller. Means are provided to obtain simultaneous operation of both pawls by a single control element.

    In this case, the shaft for winding the belt can be made hollow, and the connecting shaft, is installed in the cavity of the shaft. In addition, an intermediate tube can be installed parallel to the belt winding shaft, and the connecting shaft is placed in the latter. Distributing cams are located between the pivoting dogs, which are interconnected by the said connecting shaft. , Figure 1 shows the device, a longitudinal section; Figures 2-6 illustrate embodiments of the device with a radial locking of the ratchet wheel from the inside outwards, transverse section / Figure 7-11 embodiments of the device with a radially locking snapshots wheel outside in the inside direction, transverse section. The emergency locking retracting device comprises (FIG. 1 a body formed by side shastins 1 and 2 rigidly connected with a C-shaped part 3 having an opening 4 for fastening the case on the frame of the car. In the case there is a coil with a shaft 5 for winding the tape 6 belt, having a radial slot 7 for fixing: the free end of the tape end, made in zone 8 with expansion for easy fixation. The plates 1 and 2 are kept at a certain distance from one another by means of an intermediate piece 9. On one protruding plate At the 2 end of the shaft 5, one end of the coil spring 10 is fixed, the other end is fixed to the housing part 3. On the opposite side, the console -1 .. but from the bottom of the plate 1 on the mounting nozzle 11 of the shaft 5 is mounted for rotation the control disk 12 connected to the inertial disk 13. An inertial mechanism 14 is connected with the latter by coupling its flexible teeth, which includes an inertial element (ball) 15 and a control lever 16. In the first embodiment (FIG. 2), on one end of the shaft 5, a spring-loaded pawl 18 is mounted, spring-loaded 17, an engaging cam 12 of the control disk 12 for locking the ratchet wheel 20 fixed to the plate 1 with internal teeth 21. The pawl 18 is rigidly connected with another rotary pawl 22 mounted on the outer side of the plgastine 2 before the spring 10 to interact with the inner teeth of the second ratchet wheel 23. Plates 1 and 2 can be closed with covers 24 and 25. Made of synthetic material and the shaft 5 (FIG. 2) for winding a belt is provided with an amplifying yes-. a hoist, for example in the form of a metal pin 26 passing through the shaft parallel to its axis. Swivel dogs 18 and 22 are made in the form of single-arm levers, each of which has a tooth 27. Both dogs are rigidly interconnected by a connecting room 28, in the corners of the plates 1 and 2 are open outward notches 29, in which intermediate part 9 is installed and fixed The embodiment according to FIG. 3 on the front surface of the shaft 5 on the axis 30 is mounted to rotate the control lever 16 in the form of a segment, and on axis 31 - the pawl 18, spring-loaded 17 spring and having, like the corresponding pawl on the opposite side ala, teeth 32. For the rotation of the control lever is provided the control 16 yuschy cam 33 and the lever 16 - 34. The tooth. The embodiment according to FIG. 4 is based on the example of the embodiment of FIG. 3, in that the belt shaft 5, provided with a mounting flange 35, has several reinforcing rods 36. In the embodiments examples of FIGS. 5 and 6 on each side 5 two dogs 18 and 22 are mounted, fixed, for example, on the flange 35 of the shaft (figure 4), with the possibility of a permutation. In the example of the embodiment of figure 5 the dogs 22 are made in the form of single-shouldered levers having a tooth 32. position, usually parallel to one another and in opposite directions, sob The ki 22 is spring-loaded relative to each other by a single tension spring 17, while two jaws 33 are mounted in the gap between the two dogs. In the example of the embodiment of Fig. 6, the dogs 18 are located in the guides 37, made in the form of elongated holes and abut one the other radial edges 38, These dogs 18 are spring-loaded relative to each other, as in the example of FB, one tension spring 17, are mounted on both sides of the -,, - shaft 5 and are made with one tooth, FIG. 7 and the following figures which protrude beyond the plate 1 end into The ala 5 is made with the outer teeth 39 for engagement with the paws 18 and 22 mounted on both sides of this shaft, moving from the outside to the outside. . In the exemplary embodiment of Fig. 8, the latter are in the form of single-arm elongated levers, made with three teeth 32 for engagement with the teeth of the dogs. Both dogs are rigidly connected. With each other by a shaft 28 located in the intermediate pipe 40, which fixes both plates 1 and 2 relative to. each other (Figures 7 and 8}. To drive the pawl 18 serves a cam 41 connected to the control disk 12, having a lead 42 installed in the guide 37 in the form of an elongated hole. The shaft 5 of the belt is hollow of synthetic material and provided with two reinforcing details 43.
    In the embodiment of FIG. 9, the pawls 18 and 22, installed along o (5th, pinches of the shaft 5) are rigidly interconnected by a shaft 28 by means of the teeth 32, while the pivot axes of the pawls are located in open recesses 29 open as elongated holes.
    To protect against extraneous influences, the shaft 28 is installed in the zone of the intermediate angle 44, which connects it between the plates 1 and 2 of the housing and overlapping the specified shaft on both the headphones. The latter is made, for example, in the form of a hollow part, of synthetic material and provided with two rectangular reinforcing plates 45, while in the example of embodiment of Fig. 11 the shaft 5 of the belt is stabilized by four reinforcing parts 46.
    In contrast to the described embodiments in the embodiment of Fig. 10, the axis .47 of the connecting shaft is located in the L-shaped opening 48 facing outward, and the mounting of the shaft 5 is facilitated by the recesses 49 in the form of elongated holes made in the plates 1 and 2.
    The device works in the following way.
    When a certain amount of acceleration or deceleration of the vehicle occurs under emergency conditions, the inertial element 15 of the inertia mechanism 14 (Fig. 1) leaves the neutral position, moves the control lever 16 in the direction of the control disk 12 until it engages with the latter, as a result of which the control disk locks.
    At the same time, due to counter-movement of the shaft 5 and the control disk 12, the pawl 18 with the help of the cam 19 of the disk 12 up. This moves radially relative to the shaft 5 in an outward direction until it engages with the teeth 21 of the wheel 20.
    In the example of FIG. 2, the cam 19, when opposing the shaft 5 and the control disk 12, moves the dog 18 against the force of the spring 17 to the locking position, in which the tooth 27 of the dog engages with the teeth 21 of the storage wheel 20.
    In the embodiment of FIG. E; BosHHi ioveniya counter-movement of the shaft 5 and the disk 12 cm control lever 16 engraving is rotated by means of a cam 33,
    as a result, on one side of the fish-: chag 16, the tooth 34 engages with the teeth 21, as a result of which with the casing 18 its teeth 32 intermesh with the ratchet teeth, overcoming the force of the spring 17.
    In the exemplary embodiments of FIGS. 5 and 6, with the indicated counter-movement of the shaft and control disc, the cams 33 simultaneously radially move the pawls 22 to the outside parallel to each other before engaging with the ratchet teeth.
    In the rest of the examples, the belt is locked in the same way.
    The described device structure protects the belt locking mechanism, i.e. increases the operational reliability of the device.
