Definitions
- the invention relates to a belt buckle with a lock holder set up for mounting on a vehicle part, the lock holder having a hole for the passage of a fastener to be prevented with the vehicle part such that the lock holder is rotatably held on the fastening means, and wherein between the vehicle part and the lock holder a return spring biasing the lock holder into the rest position of the belt buckle and with one end against the lock holder and with the other end supporting the vehicle part is arranged with helically arranged spring windings.
- a belt buckle with the generic features is described in EP 0 854 070 B1. So that the belt buckle can move from its rest position to set an optimal belt course, the buckle holder is rotatably mounted with an elongated hole on a fastening bolt for the buckle holder, the elongated hole also allowing a translational movement of the buckle to the fastening means.
- a spiral spring is provided with a first helical spiral section, the spring windings of which are arranged axially next to one another with the same diameter of the spring windings and enclose the fastening bolt.
- a second spiral section is arranged between the first spiral section and the end of the spring which is supported on the belt buckle. While the first spiral section of the return spring provides for its return about the axis of rotation when the lock holder is rotated about the fastening bolt, the second spiral section causes the lock to be reset after its translational displacement.
- the known belt buckle has the disadvantage of a correspondingly large axial width of the fastening arrangement for the belt buckle; furthermore, the second spiral section provided because of the translational resetting of the belt buckle complicates the resetting in its dimensioning and manufacture.
- the invention is therefore based on the object of providing a simply constructed return spring for a belt buckle with the generic features.
- the return spring is a flat spiral spring with spring windings arranged in one plane, which is arranged between the lock holder and a cover as an abutment.
- the invention includes the finding that in addition to the restoring effect of a coil spring with spring windings arranged in a plane and with an outwardly increasing radius around the axis of rotation extending through its center, a translational displacement of the lock holder with the inner end of the coil spring attached thereto has its tangential movement in the same How the tension of the coil spring causes when the lock holder rotates around the fastening bolt without having to set up a special spring course. According to the flat spiral spring between the Lock holder and an outer cover clamped so that the spring turns of the flat spiral spring can not avoid.
- the invention has the advantage that the axial width of the fastening arrangement for the lock holder on the vehicle part is significantly reduced, since an installation space is only required for a flat spiral spring, that is to say in the order of magnitude of the material thickness of the spring wire usually used for the production of the spiral spring, must be provided.
- the endurance behavior of the flat spiral spring used according to the invention is better than that of the helical spiral spring known from the prior art.
- the cover has a bearing opening for the fastening means to pass through, so that the cover is in particular fixed non-rotatably with respect to the vehicle part, so that it is suitable as an abutment for the return spring.
- the cover is additionally fixed to the vehicle part in a form-fitting manner by means of the fastening means.
- the outer end of the flat spiral spring is fixed to the cover and the inner end of the flat spiral spring engages the lock holder.
- the cover with a first radial approach for hanging the outer end of the flat coil spring and is provided with a second approach as a stop for the return of the lock holder.
- a third radial projection is arranged so that the buckle holder in its rest position between the second and the third approach clamped and thus rotatable in only one direction.
- the positive locking of the cover provided according to one embodiment of the invention can be expediently achieved in that the third extension has an opening for the passage of a pin located on the vehicle part.
- 1 is a belt buckle with lock holder and fasteners including return spring in a sectional side view
- Fig. 2 shows the subject of Figure 1 in a front view.
- FIG. 3 shows the subject of Figure 1 in a
- a belt buckle 10 is firmly connected to a buckle holder 1 1, at the end of which facing away from the buckle 10, an elongated hole 12 is formed for the passage of a fastening screw 13, the fastening screw 13 in a vehicle part, not shown, as the carrier of the Lock holder 1 1 with buckle 12 is screwed.
- a cover 14 is provided which covers the lower end of the lock holder 1 1 with slot 12 and has a bearing opening 15 with a countersink for the screw head of the fastening screw 13, so that the fastening screw 13 lies flush in the cover 14.
- a washer 16 is arranged on the screw shaft of the fastening screw 13, which extends with a collar 17 into the slot 12 of the lock holder 1 1, so that the collar 17 of the washer 16 on the one hand as a rotary bearing for the lock holder 1 1 and on the other hand as Guide for the translational displacement of the lock holder 1 1 with the slot 12 on the collar 17 is used.
- a spiral spring 18 is arranged as a return spring, the windings 19 of which extend in one plane with a radius that increases from the inside to the outside; the inner end of the spiral spring 18 is suspended on the lock holder 11, while the outer end of the spiral spring 18 is fixed on the cover 14.
- the cover 14 has a first radial extension 20 for attaching the outer end 24 of the spiral spring 18, and also a second extension 21 as a stop for the return of the lock holder 11.
- the stops 20, 21 point in FIG the level of the lock holder 1 1 reaching offsets 22.
- the inner end 25 of the spiral spring 1 8 is suspended in an opening 26 of the lock holder 11.
- the second radial extension 21 diametrically opposite on the other side of the center line of the lock holder 1 1, a third radial extension 27 is arranged, which has an opening 28 for the passage of a pin on the vehicle part, not shown, also not shown for positive locking of the cover 14 on the vehicle part.
- the lock holder 1 1 is clamped in its rest position between the second extension 21 and the third extension 27 and rotatable in only one direction of rotation.
