Definitions

  • the invention relates to a belt retractor for a safety belt, with a frame, a belt spool, which is rotatably mounted in the frame, a locking mechanism that can respond vehicle and / or belt-sensitive, and a force limiter, which is functionally arranged between the belt spool and the locking mechanism ,
  • Belt retractors with a force limiter are well known.
  • the force limiter is used to release a certain length of webbing in case of restraint, despite being blocked on itself belt reel to prevent excessively high deceleration forces.
  • it is basically desirable to limit the belt extension to a predetermined level. If no limitation is provided, under certain circumstances so much webbing can be pulled off the belt reel that the restraining effect of the seat belt can be improved under unfavorable conditions (for example very heavy vehicle occupant, second impact after a first impact, very oblique impact).
  • the object of the invention is to develop a belt retractor of the type mentioned in that with the least possible effort a reliable limitation of Gurtbandauszugs during a force limiting operation to a predetermined level is possible.
  • a Auszugsbe dictionary is provided according to the invention in a belt retractor of the type mentioned, which is arranged functionally between the belt reel and the frame.
  • the invention is based on the idea to use a separate from the force limiter Auszugsbe dictionaryr which is effective directly between the belt reel and the frame. In this way, the high loads that occur in limiting the rotation of the belt reel at the end of a force limiting operation can be reliably intercepted.
  • the locking mechanism has a locking part which can be blocked by the locking mechanism frame-fixed and to which the force limiter is connected.
  • the locking member is rotatably held relative to the frame when the locking mechanism vehicle or gurtband sensitive responds. The necessary for a force limitation rotation of the belt reel then takes place relative to the locking part.
  • a torsion bar is used as the force limiting element. This can be arranged to save space inside the belt reel.
  • the pull-out limiter preferably includes an activation mechanism responsive to relative rotation between the lock member and the belt reel. So there is no need for an external sensor or an active actuator that activates the pull-out limiter. Instead, the pull-out limiter is controlled directly on the basis of the only relevant parameter, namely the number of rotations of the belt reel during the force limiting operation.
  • the activation mechanism has a switching element which is attached to the locking part. This makes it possible to directly use the rotation of the belt reel relative to the locking member for the activation of the extension limiter.
  • the activation mechanism may include a thread associated with the locking member and a mating thread associated with the activating member. The pitch of the thread and the counter thread are chosen so that is activated relative to the blocking part of the Auszugsbegrenzer after the desired number of revolutions of the belt reel.
  • the mating thread is attached to a threaded sleeve. This results in a very simple structure.
  • the activation mechanism includes an activation pawl, which is pivoted in a relative rotation between locking part and belt reel from a rest position to an activation position.
  • the activation pawl makes it possible, for example, to synchronize a locking disk with the belt spool during the force limiting operation so that it can be coupled to the belt spool.
  • the activation mechanism may also comprise a counting disc, a wrap spring or a spiral mechanism, all of which initiate load transfer from the belt reel to the frame after a predetermined number of revolutions of the belt reel relative to the blocking member.
  • the extraction limiter has a load pawl, which can be controlled in a frame associated with the toothing.
  • a load pawl is a very compact component, with which the forces acting on braking of the belt reel at the end of a force limiting operation can be transmitted reliably.
  • the toothing is arranged on a threaded ring, which is mounted rotatably limited to the frame. This makes it possible to constructively determine the number of revolutions of the belt reel which it can perform during a force limiting operation.
  • the toothing is provided on a ring, which is mounted limitedly limited under damping damping on the frame.
  • the damped free travel around which the ring can be turned on the frame ensures that the load pawl is substantially load-free in the toothing can be controlled. This prevents that during the control of the load pawl tooth tips of the load pawl and the toothing can impinge on each other under load and can be damaged.
  • the toothing is mounted directly on the frame, in particular carried out in the frame.
  • This embodiment is characterized by a simple structure and low costs.
  • the toothing is undercut. This supports the control of the load pawl in the teeth even under load.
  • the extraction limiter has a friction disc which can cooperate with the frame.
  • a frictional action is used to block the belt reel toward the end of the force limiting operation and to prevent further belt webbing withdrawal.
  • the friction disc is provided with at least one obliquely aligned pressure surface.
  • a thrust washer can be used, which is non-rotatably connected to the belt reel. In this way, the pressing force with which the friction disc is pressed against an associated mating surface, generated directly from the belt reel itself.
  • the belt reel is provided with a counter surface which can cooperate with the frame.
  • the frame is thus clamped between two "brake pads", namely on the one hand, the friction disc and the other of the belt reel.
  • the extraction limiter contains a stop disk which can be coupled to the belt reel.
  • This embodiment is based on the idea of providing a separate component with the stop disk, which is kept stationary in normal operation and only in a force limiting operation with the Belt spool is coupled to limit the rotation of the belt reel relative to the locking member to a desired value.
  • the stop disc has a coupling toothing, which can be brought into engagement with a complementary coupling toothing of the belt reel.
  • the coupling teeth allow it with little effort to transmit the necessary forces to limit the rotation of the belt reel.
  • the activation pawl is used to synchronize the stop disc with the belt reel.
  • the activation pawl can engage in the coupling teeth, so that it entrains the stop disk.
  • a stop is preferably provided, which can engage in a complementary stop on the frame. In this way, the forces can be transmitted directly from the belt reel on the coupling teeth in the stop disk and from there into the frame.
  • a control disk which is provided with Ausmaschineschrägen, with which the stop disk can be moved in the axial direction in a stop position.
  • the Ausberichtschrägen make it possible to move the stop disk in the axial direction at a desired time so that their stop can engage in the complementary stop on the frame.
  • a coupling mechanism which couples the control disk to the stop disk until the belt reel has made a predetermined number of revolutions relative to the locking member. By selecting the number of revolutions that the control disc can perform together with the stop disc, the amount of webbing that can be withdrawn from the belt reel during a force limiting operation is determined.
  • the coupling mechanism may in particular be a shear pin or a coupling spring, which has a predetermined torque between can transmit disc and control disk. This results in a very compact design.

  • the belt retractor includes a frame 10 having a back portion 12 and two side flanges 14. Between the two side flanges 14, a belt spool 16 is rotatably mounted. On the belt reel 16, a (not shown) webbing of a seat belt can be wound up. On her (relative to Figure 1) right side of the belt reel 16 is provided with a locking member 18 which is provided with a schematically indicated locking teeth 20. In the interior of the locking member 18, one end of a torsion bar 22 is rotatably received, the other end is rotatably connected to the belt reel 16.
  • a schematically illustrated blocking pawl 24 cooperate, which is part of a locking mechanism 26 schematically indicated here.
  • the locking mechanism 26 may in a conventional manner, the locking member 18 webbing-sensitive or vehicle-sensitive block, so that it does not rotate relative to the frame in the withdrawal direction of the webbing.
  • a Auszugsbe dictionary 28 is arranged, which has a mounted on the end face of the belt reel load pawl 30. This is mounted by means of a pivot bearing 32 on the end face of the belt reel that they can be pivoted under the action of a compression spring 34 from the starting position shown in Figure 2 so that a toothed portion 36 at the end facing away from the pivot bearing 32 of the load pawl 30 in a toothing 38 can be controlled.
  • the load pawl 30 is held by a switching element 40 (see in particular Figure 3), which has a protected sleeve 42.
  • a coupling toothing 44 which is rotatably connected to the locking member 18, and at the other end with a control pin 46.
  • the control pin 46 extends through a slot 48 which is circular section-shaped, from the front side of the Belt spool 16 and is applied to the load pawl 30 so that it is held in its initial position when the torsion bar 22 is in the initial state.
  • the toothing 38 is formed on the inner circumference of a threaded ring 50 which engages with its external thread in an internal thread of a counter-ring 52 which is rotatably held on the side flange 14 of the frame 10.
  • the counter-ring 52 has a stop flange 54 which, in the starting position shown in Figure 1, a few threads away from the position in which the threaded ring 50 is located.
  • the belt reel 16 can rotate freely, since the load pawl 30 is held by the control pin 46 in its initial position in which it does not engage in the toothing 38 of the threaded ring 50.
  • the locking mechanism 26 responds and the locking member 18 is held against rotation by the blocking pawl 24, the belt spool 16 is held against rotation, as long as the torque applied to them is less than the torque which can be transmitted from the torsion bar 22 without this (noticeable ) is twisted. However, if the forces acting in the webbing exert such a torque on the torsion bar 22 that it yields, the belt spool 16 begins to rotate relative to the locking part 18.
  • the load pawl 30 Since the control pin 46 fixed with coupled to the locking member 18, the load pawl 30 is rotated relative to the control pin 46 at such a relative rotation between the belt reel 16 and locking member 18; the belt spool 16 rotates in the direction of the arrow P of FIG. 2 while the control pin 46 stops. As a result, the load pawl 30 is released, so that it engages under the action of the compression spring 34 in the toothing 38. This causes the load pawl 30 entrains the threaded ring 50 so that it screws into the counter-ring 52 inwardly toward the stop flange 54. In this process, the torsion bar 22 is twisted, so that a so-called force limiting operation takes place.
  • control pin 46 Upon further rotation of the belt spool relative to the spreader, the control pin is sheared off.
  • the control pin 46 shown it can also be arranged so that it actively displaces the load pawl 30 outwards when there is a relative rotation between the blocking part 18 and the belt reel 16.
  • inertial or centrifugal forces can be used to control the load pawl.
  • the rotation of the belt reel 16 during the force limiting operation is possible as long as the threaded ring 50 can screw into the mating ring 52. Once the stop flange 54 is reached, the threaded ring 50 can not rotate further, so that due to the engaging in him load latch 30, the belt reel 16 can not rotate. Consequently, a torque acting on the belt reel 16 is introduced therefrom via the load pawl 30, the threaded ring 50 and the counter ring 52 into the side flange 14 of the frame 10, and the force limiting operation is completed.
  • the free threads available for the nut 50 from the initial condition to tight abutment against the stop flange 54, the number of revolutions of the belt spool relative to the stop member 18 that the belt spool 16 can perform during the force limiting operation can be adjusted.
  • a second embodiment will now be described with reference to FIGS. 4 and 5.
  • the same reference numerals are used, and reference is made to the above explanations in this respect.
  • the difference between the first and second embodiments is that in the second embodiment, the number of allowable revolutions of the belt spool 16 during the force limiting operation is not adjusted by a rotation of the gearing 38 relative to the frame 10, but by a threaded mechanism inside the belt spool 16.
  • This consists of a threaded sleeve 56 which is rotatably coupled to the locking member 18, and a switching sleeve 58 which has a thread of the threaded sleeve 56 complementary mating thread and is provided with the control pin 46.
  • the control pin 46 holds the load pawl 30 in an initial position in which it does not engage in the toothing 38.
  • the toothing 38 is formed directly in the corresponding side flange 14 of the frame 10 in the second embodiment. As can be seen in Figure 5, the teeth 38 is strongly undercut.
  • the belt spool 16 rotates relative to the locking member 18, and the rotatably received in the belt reel 16 shift sleeve 58 rotates relative to the threaded sleeve 56.
  • the mating thread of the shift sleeve 58 screwed onto the thread of the threaded sleeve 56, whereby the control pin 46th is pulled inwardly in the direction of the arrow S of Figure 4.
  • the control pin 46 releases the load pawl 30, it pivots with its toothed section 36 outwards into the position shown in FIG. 5, in which it engages in the toothing 38 in the frame.
  • the belt reel 16 is held against rotation on the frame 10.
  • the number of revolutions that the belt spool 16 can perform relative to the locking member 18 until the load pawl 30 is released is determined by the length of engagement of the control pin 46 with the load pawl 30 and the pitch of the threaded engagement between the threaded sleeve 56 and the shift sleeve 58 ,
  • the belt reel 16 Due to the strongly undercut toothing 38, which acts on the load latch 30, the belt reel 16 is allowed to rotate despite a controlled load pawl 30 still by a defined angle to remain almost no load when driving to the tooth base. This reduces the loads on the teeth 38th.
  • the locking mechanism can be designed according to the highest level of force occurring. Due to the design of the extension limiter, the design of the locking mechanism is independent of whether such an extension limiter is to be integrated into the belt retractor or not.
  • Another advantage of the first and the second embodiment is that the loads which are absorbed by the belt reel when the Auszugsbeskyr has limited the relative rotation of the belt reel 16 to the locking member 18 towards the end of a force limiting operation, on the two side flanges 14 of the frame 10th be distributed to the belt retractor: On the side of the locking member 18, the torque is derived, which is transmitted from the torsion bar 22 at the end of Kraftbegrenzungsvorgangs, and on the side of the load pawl 30, the remaining torque is transmitted.
  • FIG. 6 shows a frame 10 for a belt retractor according to a variant embodiment of the second embodiment.
  • the toothing 38 is formed on a damped Leerweg ring 60, which from the initial position shown in Figure 6 with a certain damping around a free travel L can be rotated relative to the corresponding side flange 14 until it finally abuts by means of a stop 62 against a counter-stop 64 of the frame.
  • the limited rotatable toothing 38 results in that during the actual control of the toothed portion 36 of the load pawl 30 in the toothing 38 still no load can be transmitted, since the Leerweg ring 60 rotates.
  • FIG. 7 An alternative embodiment is shown schematically in Figure 7, which uses a compression spring-like wire construction 66 which engages with a turn in a retaining recess 68 of the control pin 46 and with its relative to Figure 7 left end fixed to a retaining sleeve 70 which rotatably with the Locking member 18 is connected.
  • a central turn of the wire construction 66 engages in the retaining recess 68, so that the control pin 46 is held in a starting position.
  • the basic difference between the third embodiment and the previous embodiments is that in the third embodiment, no load pawl 30 is used, but a friction disc 72, which can apply a sufficiently high friction torque, with the belt reel 16 at the end of a force limiting operation rotatably on the frame 10 is locked.
  • the friction disc 72 is provided with a friction surface 74 which can cooperate with the outside of the left side flange 14 in FIG.
  • the friction disk 72 is provided with an obliquely aligned contact surface 76 provided, which faces a counter surface 78, which is also employed obliquely.
  • the mating surface 78 is disposed on a thrust washer 80 which is rotatably connected to the belt spool 16.
  • the control pin 46 engages in the friction disk 72 so that it rotates together with the belt spool 16 and the pressure plate 80.
  • this state there is a slight play between the friction surface 74 and the outer wall of the side flange 14 of the frame 10. If, during a force limiting operation, the belt reel 16 rotates relative to the blocking part 18, the shift sleeve 58 screws onto the threaded sleeve 56 until the control pin 46 releases the friction disk 72.
  • This allows a bow spring 79, the friction plate 72 relative to the pressure plate 80 to rotate so that the pressure surface 76 runs onto the counter surface 78 and thereby the friction plate 72 is displaced in the direction of the arrow P of Figure 9 against the side flange 14.
  • the friction disc 72 is thereby frictionally engaged with the side flange 14, whereby it is further braked, which increases the pressure effect of the pressure plate 80. This results in a braking effect, by which also lies within the side flange 14 end face against the side flange 14 is pulled.
  • the side flange 14 then acts like a brake disc which is clamped between two brake linings (friction surface 74 and end face 80 of the belt reel 16). In this way, further rotation of the belt reel is prevented after the end of the force limiting operation.
  • a stop disc 84 is used instead of a load pawl, which is provided with a coupling toothing 86 and a stop 88.
  • the coupling toothing 86 can be brought into engagement with a complementary belt spool coupling toothing 90 which is embodied on the belt spool 16 so that it lies on the outside of the frame 10.
  • the stop 88 of the stop disc 84 can be brought into engagement with a frame stop 92.
  • the stop disk 84 is arranged inside a control disk 94 (see in particular FIG. 14), which is provided with a plurality of control ramps 96 on its inner circumference. These can interact with counter-bevels 97, which are arranged on the control disk 94. Furthermore, 94 more retaining lugs 98 are provided on the control disk 94.
  • the control disk 94 is provided on its outer periphery with an external thread 100, with which a counting ring 102 is engaged. This is rotatably on retaining lugs 103, but slidably received in the axial direction in a housing 104 which is fixedly mounted on the side flange 14 of the frame 10.
  • the counting ring 102 is at a distance from an end flange 106 of the control disk 94, and the stop disk 84 is held behind the retaining lugs 98 so that they on the side facing away from the end flange 106 axial side of the control disk 94th lies.
  • an activation pawl 108 is mounted, which can be pivoted from its initial position shown in Figure 12 in an outwardly pivoted activation position, in which it engages the coupling teeth 86 of the stop disk 84.
  • the activation pawl 108 is connected by a connecting member 110 with a retaining lever 1 12, which is in its initial state, so when the belt reel 16 is not rotated relative to the locking member 18, supported on its inner side. Characterized the activation pawl 108 is held against the action of the compression spring 34 pivoted radially inwardly. If there is a relative rotation between the belt reel 16 and the locking member 18, the retaining lever 1 12 is released, and the activation pawl 108 is pivoted by the compression spring 34 to the outside.
  • the stop 88 Due to the axial displacement of the stop disk 84, the stop 88 now passes into the region of a recess 116 in the side flange 14, which, viewed in the direction of rotation, lies in front of the frame stop 92. In the continued rotation of the belt reel 16 of the stop 88 of the stopper 84 is finally against the frame stop 92, whereby further rotation of the belt reel 16 is prevented.
  • the suitable arrangement of the stop disk 84 relative to the frame stop 92 and the suitable choice of the thread pitch of the external thread 100 of the control disk 94 ensures that the stop 88 of the stop disk 84 synchronized in the activation case dips into the recess 116 immediately in front of the frame stop 92.
  • the activation pawl 108 could also be activated actively or using inertial or centrifugal forces.
  • a spring element could also be used which provides sufficient frictional force between the stop disc and the control disc.
  • Another advantage is that the separation of the load mechanism from the counting mechanism, the components can be carried out inexpensively.
  • FIG. 18 shows a variant embodiment which uses a drag ring 120 instead of the counting ring 102, with which just under two revolutions of the belt reel 16 are permitted before the stop disk 84 is pushed onto the belt reel coupling toothing (not visible here).
  • the towing ring 120 has an inner stop 122 and an outer stop 124.
  • the outer stop 124 cooperates with a control disc stop 126
  • the inner stop 122 cooperates with a frame stop 128 which is rotatably held relative to the frame 10 of the belt retractor.
  • the control disc stop 126 is located at the position shown in dashed lines.
  • the control disk 94 also rotates.
  • control disk stop 126 first passes from the dashed position into the position represented by a solid line in FIG. 18, in which it bears against the outer stop 124 and continues to move in the direction of the arrow P.
  • the inner stop 122 comes into abutment against the frame stop 128, so that the drag ring 120 and thereby also the control disk 94 can no longer rotate.
  • the stop disc 84 continues to rotate with the belt spool 16
  • the pressure bevels 97 of the stop disc 84 shift relative to the control disc 94, so that the stop disc 84 is displaced in the axial direction toward the center of the belt spool 16 and engages the belt spool.
  • Coupling teeth 90 passes. This then allows engagement of provided on the stop disc 84 stop with the frame stop.
  • FIG. 19 shows a further embodiment variant which uses a different mechanism in order to achieve an axial displacement of the stop disk 84 after a predetermined number of rotations of the belt reel.
  • an intermediate ring 130 is used, which with a Counting teeth 132 is provided. This cooperates with a pinion of stepped gears 134 whose larger gear interacts with a sun gear 136.
  • the activation pawl couples the stop disc 84 and the intermediate ring 130 with the belt spool, they rotate together with the control disk 94.
  • step gears 134 cause a slight relative rotation between the control disk 94 and the intermediate ring 130 per revolution of the control disk 94 relative to the sun gear 136 until it turns into axial direction is released and is displaced by the Aus Kunststoffschrägen 96 in the axial direction.
  • the stop disk 84 engages with the frame coupling toothing 90 of the belt reel, so that the stop 88 on the stop disk 84 can finally fix the belt reel relative to the frame.
