Definitions
- the invention relates to a belt buckle device for a safety belt with the features of the preamble of An ⁇ claim. 1
- the drive device is formed by an electric motor
- this is designed as a small-sized electric motor with a very high speed and a very low inertia.
- the high speed of the electric motor is therefore expedient, as this sufficiently high forces can be realized with the interposition of a corresponding gear.
- the low inertia of the electric motor is of the semi ⁇ useful because the high speed of several thousand revolutions per minute, characterized in a very short time of GR a few milliseconds.
- a possible embodiment of the transmission is to provide on the pull rope of the buckle a threaded sleeve, which is in engagement with a spindle driven by the electric motor threaded.
- the electric motor can move the threaded sleeve by rotational movements in different directions of rotation in un ⁇ different directions, can be realized by Verwen tion of the electric motor as a drive device both the Gurtschbringerfunktion and the tightening function of Si cherheitsgurtes.
- the object of the invention is to provide a belt buckle device for a safety belt with a drive device and a belt lock, which can be designed to be optimized both for the transmission of the drive movement of the drive device and for the absorption of the restraint forces in the accident.
- a non-displaceable bearing plate be provided on the threaded spindle, at least in the axial direction of the threaded spindle against a tension exerted by the buckle, via which the threaded spindle in the axial direction on a first abutment of the guide member for receiving on the buckle supported tensile forces.
- the proposed solution the axial forces occurring during retraction of Gurtschlos ⁇ ses and especially when tightening the webbing are introduced from the threaded spindle on the bearing plate and the first abutment in the vehicle structure, so that the drive device itself and the parts between the bearing plate and the drive device through the tensile forces acting on the buckle are not stressed.
- the transmission transmitting the drive motion may e.g. be made inexpensively from plastic parts. Furthermore, the life and reliability of the drive device can be significantly increased and improved due to the lower load.
- the threaded spindle is supported on a second abutment for receiving pressure forces exerted on the buckle.
- the drive device is thus controlled exclusively by the torque acting during the transmission of the rotational movement. It does not have to be specially stored or designed in addition to absorbing any axial forces.
- the second abutment can be used in addition to a radial bearing and at least to limit the radial movement of the threaded spindle by the second abutment having an opening through which extends the threaded spindle.
- the threaded spindle can thereby be extended through the second abutment for connection of the drive device.
- the bearing plate has a Publ tion through which the threaded spindle extends
- the bearing plate can be used with the same advantages as the second abutment for radial bearing and limiting the radial movement of the threaded spindle and also extended through the bearing plate therethrough.
- the proposed axial bearing of the threaded spindle can be realized structurally particularly simple by the Ge ⁇ threaded spindle has a radial shoulder, and the threaded spin del the threaded sleeve facing away from the threaded sleeve edge of the opening of the bearing plate and / or the threaded sleeve facing edge de second abutment covered with the paragraph ,
- the forces exerted during the retraction of the buckle tensile forces on the second abutment and acting on the threaded spindle during extension of the buckle pressure forces on the bearing plate and the first abutment can be added.
- Such storage can be structurally particularly simple, if the heel of the threaded spindle between the bearing plate and the second abutment is arranged.
- the threaded spindle can be stored particularly well if it passes through the opening of the bearing plate and / or the opening of the two ⁇ th abutment with a thread-free section. As a result, a particularly large bearing surface with a low surface load of both the threaded spindle itself and the bearing surface can be realized.
- the bearing can be further improved by the threaded spindle is mounted in the opening of the bearing plate and / or in the opening of the second abutment each by means of a friction-reducing bearing insert.
- the proposed solution the friction losses and the Ge ⁇ noise development can be reduced during the drive of the threaded spindle.
- the bearing clearance can be set lower ⁇ by the bearing inserts are manufactured with a higher dimensional accuracy than the guide member.
- FIG. 1 shows a detail of a belt buckle device according to the invention in an oblique view
- FIG. 1 shows a detail of a belt buckle device 1 according to the invention and a drive device 2, wherein the belt buckle itself has to be considered and From the drive device 2 only the drive gear can be seen.
- the drive device 2 also includes a unit that generates the drive movement, such as an electric motor, for example, which then drives the drive gearwheel, for example via a toothed belt or a toothed gearing.
- the belt buckle device 1 further includes a rotatably connected to the drive means 2 threaded spindle 10, a guide member 12, a fixedly connected to the guide member 12 mounting member 3 for attachment to a vehicle structure and guided in the guide member 12 threaded sleeve 5, in which the threaded spindle 10 with the Thread engages.
- the threaded sleeve 5 is in turn zug- and pressure-resistant connected to a pull rope on which the buckle is held.
- the threaded spindle 10 is rotationally driven via the drive gear, so that the threaded sleeve 5 is moved depending on the direction of rotation of the threaded spindle 10 to a linear movement of the drive gear or on this, and the buckle is thereby either retracted or extended over the traction cable 4.
- the threaded sleeve 5 is formed as a U-shaped stamped part with a threaded insert and covered by a cover 8 to the outside.
- the threaded spindle 10 is mounted with a thread-free bearing extension 11 in an upstanding bearing flange 18 of the guide member 12 and further comprises an adjacent to the end connected to the drive gear end disposed radial shoulder 15.
- a first abutment 6 is provided, on which a bearing plate 9 is supported.
- the bearing plate 9 has an opening 16 in which the threaded spindle 10 is mounted with a first friction-reducing bearing insert 13.
- a second abutment 7 in the form of a Nes externally attached to the guide member 12 forming part provided, which also has an opening 17 in which the threaded spindle 10 is mounted with a friction-reducing second bearing insert 14.
- the threaded spindle 10 through ⁇ thus engages the two openings 16 and 17 in the second abutment 7 and the bearing plate 9, and the radial shoulder 15 is disposed between the second abutment 7 and the bearing plate 9 and the first abutment 6.
- the threaded spindle 10 is supported during the drive movement in dependence on the direction of rotation in the axial direction either on the second abutment 7 or on the bearing plate 9 on the first abutment 6. So ⁇ far the buckle to be withdrawn, the threaded spindle 10 is driven in a rotational direction in which the threaded sleeve 5 is moved in the illustration of FIG. 3 to the left. In this case, the threaded spindle 10 is supported via the bearing plate 9 on the first abutment 6. In the event that the buckle is extended, the threaded spindle 10 is driven in the other direction of rotation, so that the threaded sleeve 5 is moved in the illustration of FIG. 3 to the right.
- the threaded spindle 10 is supported on the guide member 12 via the second abutment 7.
- the first abutment 6 with the adjacent bearing plate is designed deliberately stiffer, since the expected axial forces during retraction, ie during the tightening of the webbing, are generally greater than the axial forces during extension of the buckle, provided the movement of the Belt buckle is not disturbed by jammed objects or other external circumstances.
- the threaded spindle 10 is in the sections with which it passes through the openings 16 and 17, executed thread-free, but this can also be realized by the sliding of unthreaded bearing inserts 13 and 14, so that the bearing load is reduced and the rotational movement is not disturbed.
- the advantage of the proposed solution is the fact that the forces exerted on the threaded spindle axial forces are deliberately introduced into the guide member 12 and above in the vehicle structure. This can prevent that the drive device 2 is loaded by axial forces. In addition, this can of course also be achieved an improved storage of the threaded spindle 10 in the radial and axial directions.
