    An emergency locking retractor for a vehicle safety belt has a spool rotatably mounted on a frame, primary locking means arranged to block rotation of the spool relative to the frame and secondary locking means for actuating the primary locking means. The secondary locking means including an inertia sensor and a pawl pivotally mounted on a carrier which is movable relative to the frame, the pawl being movable by the inertia sensor into simultaneous engagement with a stop member on the carrier and a ratchet wheel coupled to the spool so that subsequent rotation of the spool of the belt protraction direction causes movement of the carrier which in turn actuates the primary locking means. The stop member is so positioned relative to the pivotal mounting thereof that the pawl comes into abutment with the stop member before its pawl tip abuts against the periphery of the ratchet wheel between adjacent teeth thereof.

    The invention relates to vehicle passive safety devices and relates to the design
    emergency locking retractor for seatbelt of a motorized vehicle.
    The purpose of the invention is to increase the durability of the device.
    FIG. 1 shows a disassembled, emergency locking retractor device according to a first embodiment of the invention; Fig. 2 shows an inertial sensor and the described device interconnected with it in an open position, side view; in fig. 3 - the same, in the closed position; in fig. 4 - the same 5 side view (the second version of the device).
    The swiveling device (FIG. 1) comprises a U-shaped frame 1, the base 2 of which is provided with an opening 3, by means of which the frame 1 can be attached to the body of a motorized vehicle. The side end portions of the U-shaped frame are identical elements 4 and 5, each of which contains a hole, usually circular in shape, but slightly enlarged in the vertical direction (oval), which is made with a corresponding toothed segment 6 that is part of its upper periphery.
    The coil 7 is mounted in the frame 1 and comprises a central shaft 8 for winding up the seat belt, two gear disks 9 and 10 for engaging with the gear segments 6 on the frame elements 4 and 5, respectively, and two protruding pins 11 and 12.

    , the target parts 1 h and 15 protrude beyond the edges of the holes in the elements 4 and 5 of the frame, blocking the gear disks 9 and 10 of the coil and preventing its axial displacement. In addition, the spacer rod 13 has hook ends 18 and 19 at both ends, which serve to hold the cartridge X of the spring of the retractor — with the outer side surface of the frame element 5, and the wash cartridge 21 — with the outer side surface 4 frames.
    The end piece 22 for the cassette 20 of the spring of the swiveling device is adjacent to the frame member 5 and hooks with a hooked structure to the lid 23 holding the stopper (not shown) to which the outer end of the pull-in spring 24 is attached. The inner end of the spring is attached to the plastic insert. 25 having a cylindrical outer surface and a slot-shaped hole for engagement with the flat end of the reel pin 12. The length of the sleeve 25 in the axial direction of the god.
     above the width of the spring 24, as a result of which one end protrudes into the opening 3 in the plastic support plate 26, which is installed with a slip in the elongated recess 27 in the surface of the end plate 22 ". In the recess 27, an elongated slot 28 is located in the center 27 which pin 1 and the sleeve protrude on the support plate 26, the length of the recess 27 and the slot 2S is such that the support plate 26 can slide between the position,
    in which the teeth on the disk 10 are engaged with the toothed segments 6 at the end of the plate B, and the position in which they do not engage. The spring 29 engages with a bend on the support plate 26 to shift to the release position,
    The locking mechanism cassette 21 is enclosed by the end plate 30, which is adjacent to the outer surface of the frame member 4 and hooked by the hook structure 18 on the spacer pin 13 to the lid 31. The end plate 30 has an elongated slot 32 and a slide support 33 that is offset from the toothed segments 6 on the end plate 4 by means of the prunes 34, like the corresponding components of the cassette 20, are spring retractors. In the cassette 21 of the locking mechanism, the bushing 25 is replaced with a pin 35, which is rigidly attached to the ratchet wheel 36, while the pin 35 has a cylindrical outer surface for engagement with the support 33 and a notch for engagement with the flat coil 7 ′
    The slide bearing 33 is a complete part of the control element 37, which is subject to angular displacement in the direction of the belt retraction by means of the extended end part 38 of the spring 34. The dog 39 is rotatably mounted on the control element 37 so that it can move into engagement with the teeth of the ratchet wheel 36 by means of a conventional inertial sensor 40 of the ball type in a conical seat mounted on the bottom of the end plate 30. The control element 37 has an opening 41 in which Roe includes a finger 42 attached to the end face plate 30.
    The locking mechanism cassette 21 also contains a belt-tensioning drive mechanism (of a conventional type). The tensioning strap locking mechanism consists of an inertial disc 43, which is mounted rotatably on the pin 35 of the ratchet wheel 36, and a pawl 44, which is rotatably mounted on the pin 45 attached to one side surface of the ratchet wheel 36 adjacent to it periphery. The inertial cisc 43 has a finger 46, which enters a slot in the dog 44, causes the latter to move outwards if the inertia
    the disc 43 lags behind the ratchet wheel 36. against the spring 47 when the belt is pulled out of the coil 7. If the belt
    is pulled out rapidly, then the disk 43, having sufficient inertia, overcomes the action of the spring 47, as a result of which the pawl 44 moves outwards and engages with the internal storage teeth 48 formed on the flange protruding from the control member 37, which is connected to the ratchet wheel 36 as only the mechanism 40 which perceives inertia will
    details powered by.
    After the control element 37 is connected to the ratchet wheel J6 with the pawl 39 of the inertia-sensing mechanism or the pawl 44 of the mechanism,
    tensioning belt
    due to the constant tension of the safety belt, the control plate 37 rotates around the finger 42, and the supports 26 and 33 slide along
    the slots 28 and 32, the resistance of the springs 29 and 34 up until the teeth of the disks 9 and 10 will not engage with the toothed segments 6 on the elements 4 and 5 of the frame. Once
    a turning movement of the control plate 37 begins, the mechanism will move to a position corresponding to its complete locking and remain in it until
    belt tensioning will be eliminated.
    FIG. 2 and 3 illustrate the inertia-perceptive mechanism 40 and its adjacent nodes (thanks
    a gift to break a ratchet wheel 36
    a pivotal attachment of the control element 37 is shown, but elements of positions 43 to 48 of the mechanism are not shown). The inertia-perceptive mechanism 40 comprises a carrier device 49, which is attached to the end plate 4. Tine 30 and includes a conical seat for a 5U ball. The lever 51 for tracking the ball is connected to one
    The end of the pivot mount 52 on the carrier 49 and has a protrusion 53 adjacent to its other end, which engages with the dog 39.
    The ratchet wheel 36 has a hub 54 protruding from the opposite side of pin 35 (. FIG. 1). A holding arm 555, made of elastic wire, is twisted at one end around hub 54 and is held on it from axial displacement by protrusions 56, its other end is bent to ensure engagement of pin 57 at opposite end of tip 58 of tip of dog 39.
    Control element 37 Holds three boundary stoppers 59 - 61. The stoppers 59 and 61 are located on each side of the tip 58 of the pawl and serve for; limiting the movement of the dog 39 in the clockwise and counterclockwise direction. respectively. The stopper 61 restricts the counterclockwise movement of the holding lever 55 after it has been disconnected from five of 57 dogs of the charger.
    In normal use, after wearing a seat belt attached to the retractor, the ratchet wheel 36 is moved counterclockwise to eliminate the weak belt. Due to the frictional engagement with the lever 55, the hub 54 pushes the latter under the tip 57 of the pawl 39, forcing the other end to engage the rigid engagement with the protrusion 53 and push the lever 51 tracking the ball 50, thus preventing the rattling of the latter. Between the dog 39 and the stopper 59 there is a gap a, which is less than the distance b between the tip 38 of the dog and the tips of the teeth of the ratchet wheel 36, which displaces the ball 50 necessary to move the dog 39 to engage the ratchet wheel 36. The degree of bending of the lever 51, for example as a result of deformation under adverse environmental conditions, is limited by the size of the stopper 59.
    When the self-propelled vehicle in which the retractor is mounted experiences acceleration in the horizontal direction: the tension of the seat belt increases, causing the ratchet wheel 36 to turn clockwise. Due to the frictional engagement between the hub 54 and the lever 55, the latter moves from the tip 57.
    and rests on the stopper 61. Now the dog 39 has freedom of movement, providing lateral displacement of the ball 50 from its central position in the carrier device 54, which causes the movement of the lever 51 and with it the dog 39 upwards. As soon as the tip 58 of the pawl 39 is positioned closer to the axis of the ratchet wheel 36 than the tips of its teeth, then at any further rotation of the ratchet wheel in a clockwise direction, the pawl 39 will move, enter into engagement until it stops at the stopper 60, which is positioned so as to maintain a minimum clearance between the tip of the 58 pawl and the periphery 62 of the ratchet wheel 36 (between distinguished teeth.), eliminating the possibility of breakage of the tip of the 58 pawl. The dog 39 (FIG. 3) does not come into contact with the protrusion 53 of the lever 51, with the result that the subsequent movement of the ball 50 does not affect the locking action, while the dog 39 remains in engagement with the ratchet wheel 36 until the seat belt tension will weaken.
    FIG. 3, it can be seen that between the dashed line 63 connecting the tip 58 of the dog and the axis 64 of turning the dog 39, and tangent to the periphery 62 of the ratchet wheel 36 at the moment of tangent engagement with the teeth of the ratchet wheel 36, there is an angle oi, preferably less than 25 °. This leads to an increase in the impact on the pawl 39 of the teeth of the ratchet wheel 36, which rotates into a position corresponding to its full engagement. The locking effect is further enhanced by tilting the locking surfaces 65 of the teeth of the ratchet wheel at an angle of at least 15 to its radius.
    The second variant of the device (Fig. 4.) differs from the first (Fig. 2) only in that the stopper 59 on the control plate 34 is replaced by a stopper 66 mounted on the edge of the carrier 54, which has a gap e (equal to the gap a in FIG. 2) with respect to the free end of the lever 51, which tracks the ball, when the holding lever 55 is shifted to a lap 57 of the pawl 39. Since the stopper 66 is mounted on an element that holds
    A pivotal attachment b2 of the lever 51 is installed; the accuracy of the device operation does not depend on the gaps when attaching the carrier 49 and the control element 37 to the end plate 3D. On the other hand, stopper 66 ke is the best of any kind of protection of protrusion 53, therefore the latter is reinforced by an additional edge 66,
    In another embodiment, both stoppers 59 and 66 can be made, and in this case the gap is a little larger. Die gap -., Stopper 59 is entered into the jhf-ie locking pin 39 only Dy dg - formatsich, protrusion 53, However On: Chin tin One of the stoppers 59 and 66 does not interact with the pawl 39 and the lever 51 cooTrJO i stsenno.
