    The invention relates to a vehicle passive safety system, in particular, to an automatically wedging device for a seatbelt system with a wedged seatbelt when a certain acceleration force is detected by a wedging element with which the sensor sensitive to this acceleration of the vehicle is directly connected
    The purpose of the invention is to accelerate the response of the device.
    Figure 1 shows the jamming device of seat belts with a winding device, the section; in figure 2 - the same, with a sensor sensitive to the acceleration of the belt of seat belts; on fig.Z - detail of the wedging surface of the wedging element; figure 4 - version of the sensitive to the acceleration of the safety belt mechanism, section, section; figure 5 is a variant of the jamming device as an automatic and independent jamming unit; figure 6 - part of the pivot arm; in Fig.7 - sensitive to the acceleration of the belt of seat belts sensor with lever pre-control, side view; FIG. 8 is an example of the arrangement of an automatic and independently wedging device; FIG. Fig.9 rack with a wedging mechanism of the deflecting device in the form of a combination of an automatic wedging and deflecting device, the cut.
    The automatically wedging device 1 (FIG. 1) can be combined with the storage device of the winding device 2, which consists of a winding coil with core 3 and flanges 4. The coil core 3 is wound with le; nta 5 belt-belt systems (A device for accumulating belt belt stock which maintains the belt tension of a belt with a certain force). The automatically wedging device 1 and the winding device 2 can be placed in a common body 6, with a curved groove 7 with a supporting surface 8 formed in the wedging device area. A wedging element 9 with a toothed flat wedging surface 10 is located opposite it. Between the supporting surface 8 and the wedging surface 10 passes the belt belt 5, which is wound up from the winding device 2 in the direction of the arrow 11. Between the jamming element 9 and the winding device 2 is located a ram 12, which forms an abutment for the jam element 9 in its initial position and keeps it at a short distance from the belt belt 5. The jamming element 9 is connected by a partially cylindrical open on one side of the recess 13 and is connected to the partially cylindrical swivel pin 14 of the swivel lever 15, which allows the latter to rotate around the swing axis 16, on the upper side of the swivel lever a stop 17 is formed for the jamming element 9.
    At the upper end of the wedging element 9 is placed with the possibility of rotation of the element 18 preliminary control, which is located opposite made in the wedging element 9 gutter 19. In this trench is a ball 20, on which rests the pawl element 18 of the preliminary control, which has a catching tip 21, made in the form rubber tip or small toothed surface.
    On the lower side of the pivot arm 15, a tension spring 22 is applied, which returns the pivot arm 15 after the completion of the wedging process to the initial position. To ensure that this is as reliable as possible, the bearing surface 8 has a relatively low coefficient of friction.
    The guide element 23 (figure 2) can perform the function of the belt-sensitive belt sensor 24, which can be used alone or in combination with the vehicle-sensitive sensor 25. Thus, the guide element 23 serves to form the abutment for the jamming element 9, deflection or the directions of the belt belt tape 5 and performs the function of a belt-sensitive sensor belt.
    The guide element 23 can make a reciprocating

    four
    the movement along the arrow a (Fig „2), namely against the force of the pressure spring 26.
    This spring is designed in such a way that the guide element 23 holds the belt tape 5 at a small distance x from the wedging surface 10.
    The jamming surface 10 of the jamming element 9 (FIG. 3) in the lower zone, i.e. directly next to the guide element 23, may have a rubber nozzle, which contributes to a soft initial contact between the safety belt tape 15 and the jamming element when the guide element 23 (figure 2) moves to the right (C5 + 20
    + NC).
    In the embodiment of the movement-responsive seatbelt of the jamming element 9 with the pivoting lever 15 (FIG. 4), the deflecting device 29 itself is located at the 25 end of the swinging lever 27 of the cranked lever 28. The cranked lever is rotatably mounted around the axis 30. At the end 30
    the other shoulder 31 is a powered plate 32.
    In the embodiment in accordance with FIG. 5, in the pivot arm 15; there is an open groove 33 35
    (FIG. 6), and there is also a spline 34 coaxial with it in the wedging element 9. On the swing axis 16 of the swivel lever 15, the preliminary control element 18 is located. Since before
    the groove 33 is open at the top, the preliminary control element 18 is mainly inserted into the pivot arm 15, however it has the ability to pivot in this groove around the swing axis 16. At the opposite end, a preload control element 35 is mounted, which works in the same way as the wedging element 9 of the swiveling rod of step 15. The retention element 35 with a toothed catching surface 36 drops into the recess of the precontrol element and can rotate around axis, however, cannot move along this axis, due to the small width of the element of preliminary control in the axial direction. In the direction towards the inner surface of the recess, it may have a protrusion that enters the corresponding radial recess of the support part of the gripping element. The gripping element 35 with its partially cylindrical support part can be installed in a recess with friction so that it can remain in the desired position. Due to this, the angular position of the gripping element and its gripping surface 36 may be such that the gripping element, when its gripping surface 36 contacts the seat belt, is positioned relative to the element 18 of the preliminary control and then after removal from the belt tape remains in position, so that when you next approach the belt, the entire gripping surface immediately comes into contact with the belt belt. The same effect can be achieved in combination with the jamming element 9.
    To hold the gripping element 35 in a certain position, it can be equipped on the side opposite to the gripping surface with a recess in the form of a slot 37, into which an elastically deforming tongue 38 of the preliminary control element 18 enters, when the gripping element 35 jumps into the preliminary control recess.
    The gripping element 35 protrudes through the recess in the form of a slot 39 of the jamming element 9 and, with a compact construction, can simply be brought into contact with the belt tape.
    The element of preliminary control with the aim of reducing its mass may have facilitated drilling 40
    Below the pivot arm 15 is a sensor 25 sensitive to vehicle acceleration with a thrust bearing, a ball 20 and a sensor stick 41 driven by a ball, acting on the follower 42 at the lower end of the preliminary control element 18, which projects through
    1489579
    through hole 43 of the pivot arm 15. On the opposite side is a sensor 24 that is sensitive to belt belt acceleration (FIG. 7). This sensor acts as a pin 44 in. the longitudinal hole 45 of the pulling element 46 of the element 18 of the preliminary control.
    The gripping surface 36 behind the gripping element 35 has two rows of small teeth that are directed against the direction of stretching the belt tape 5, which contributes to the effective gripping of the belt tape without danger.
    As can be seen from FIG. 6, the pivoting arm 15 outside the groove 33 has a leash 47, with which the upper side of the element 18 20 ′ comes into contact
    pre-control in the event of a lift when triggered. In the chute 48 of the pivoting lever 15 there is a partially cylindrical supporting surface 49 of the wedging element 9. The wedging part on the front side has a bearing pin 50, which is located in the insert 51 of the pivoting lever so that the load 30 is perceived when tested for sensitivity seat belt and car and long-term testing. The perception of the load after deformation of both supporting trunnions is carried out starting from 1 kN in the chute 48.
    The driver arm 52 is rotatably mounted about an axis 53 on the rotary lever 15. On the axis 54 of this lever, the shell 55 of the sensor 24 rotates with an external gear 56, which constantly engages with the belt belt 5, so that the shell rotates if the belt moves belt. A ratchet mechanism 57 is located on the driver arm 52, with the teeth of which can engage. A mass-controlled ratchet dog, if the belt is pulled out with acceleration exceeding a predetermined value, so that the driver arm 52 joins the shell 55 of the sensor 24 in such a way that the belt belt, when it is further moved, contributes to the deflection of the support arm in the direction of arrow b, i.e. clockwise (Fig.7).
    On the opposite side of the shell 55 of the sensor 24, the side of the tapered roller 58 loaded with a spring can be mounted. The sequential lever 52 is provided with a protrusion 59 which abuts against the fixed stop 60 of the pivoting lever 15 if the sensor 24 is in the initial position.
    The sheath 55 of the sensor 24 with a certain force is pressed against the belt tape 5 and thus passes along with it on the ring crown 56 without much resistance. Locking occurs, for example, when a belt is pulled out of the belt with a parameter value in the range 1.0 s-1.5.
    The advantage of this embodiment is that the direct dependence of the actuation on the acceleration of the belt belt is accelerated, the response speed is always the same, since independence of the angle of the belt deviation of the acceleration of the angle of rotation of the shaft or the diameter of the winding is set. Blocking is possible with a slight stretch of the seat belt, since any activation of the sensor introduces readiness for jamming. In addition, there is the possibility of variable layout due to the small size of the unified node. (Figure 5). The jamming device is double automatic and independent, i.e. autarkic, and maybe; mounted anywhere between the threshold of the door and the deflecting device (Fig.8 ^.
    The jamming device 1 with the housing 61 is placed in the rack 62, regardless of the winding device 2 or the deflecting device. The rack 62 has for this mounting hole 63. The mounting hole 64 is located in the lower part 65 of the rack for installation and mounting of the winding device 2.
    The jamming device is combined with the deflecting device (FIG. 9), the wired m oyesTvuyushchim with the slot 66 in the casing 69. The deflecting device 67 is an integral part of the housing 61. The wedging device and in the presented example is equipped
    7 1489579
    eight
    overlay 68 of synthetic material.
    The device (Fig „1) works; as follows $
    If the car in which the proposed device is installed experiences a certain deceleration or acceleration (exceeding 0.45 ^), then the ball 20 moves, and as a result of this, the tip 21 of the preliminary control element 18 without delay is brought into contact with the belt tape 5 security. If the passenger then moves forward with a certain deceleration and thereby winds the belt of the seat belt from the winder 2, it acts with a certain force directly on the pre-control element 20 18. Since the jamming element 9 rests on the support 17 of the pivoting lever 15, this force causes the torque of the lever M around 25 of the swing axis 16, resulting in the lower edge of the jamming surface 10 of the jamming element 9 contacting the seat belt tape, and then the jamming element 30 9 is released from the stop 17 in such a way that the entire surface 10 of the wedge comes into contact with the seat belt tape. and thereby, by winding it up, the impact 35 is exerted over the entire surface.
    If the winding of the belt is stopped, the spring 22 again returns the entire jamming system to its original position. 49
    The jamming blocking is carried out at any excess of acceleration (0.45you C5 and 1.5 § for IZ). Only in this way can a short stretch of a belt belt under load be achieved.
    The higher the threshold, the more the belt is unrolled before jamming. The devices operate at the following accelerations: 0.45 ^ / 1.5§ - operational situation during normal use of the vehicle (strong tor- $$ mosaic, sudden movement along a curve, rapid movement of the passenger’s shoulders); about 2 zyo (light collision); starting from 5§ (the beginning of an explicit accident).
    Responding to the behavior of the seat belt, the pickup sensor (FIG. 2) functions in such a way that when the belt is wound up in the range of 1–1.5, the spring 26 is compressed, as a result, the belt is in braking contact with the wedging surface 10 of the wedge element 9. As a consequence, the wedge block is fascinated by the movement of the seat belt tape, and thus the desired wedging effect occurs without delay.
    If the belt tape 5 is unwound from the reel and a certain acceleration of the tape winding occurs, then it pushes the deflecting device 29 to the right (FIG. 4), so that the crank arm 28 rotates in a counterclockwise direction. In this case, the base plate 32 transmits the movement of the rotary lever 15th and causes the wedging surface 10 of the wedging element 9 in contact with the belt tape 5, thus completing the sensitive insertion of the wedging block.
    If (FIG. 5) a seat-belt responsive sensor 24 is driven by a certain belt belt acceleration, the driver arm 52 moves along arrow b, the pin 44 of the element 18 of the pre-control rotates clockwise and thus the gripping surface 36 of the gripping member 35 comes into contact with the belt belt 5, the latter acts with force on the preliminary control element 18 so that further movement is carried out along the arrow c. Due to the lead 47, the pivoting swinging arm 15 moves in the same direction, so that the wedging surface 10 of the wedging element 9 comes into contact with the belt tape.
    When triggered by the car's sensitive acceleration sensor 25, the movement of the ball 20 causes the control pawl 41 to lift and, through the pusher 42, move the element 18 of the preliminary control, so that the same process proceeds as before. Longitudinal hole
