- a fitting of this type is known from DE 20 2010 012 621 U1.
- the eccentric which has two wedge segments, is supported on a collar of the second fitting part.
- the driver which drives the eccentric, is mounted by means of a hub in the collar and axially supported on the end face of the collar.
- the trained as a support surface end face of the collar is shown in Fig. 4 of DE 20 2010 012 621 U1 greater than the wall thickness of the collar.
- the support surface throws wrinkles and in the edge region of the support surface creates a material feed, so that the driver can not be sufficiently supported and does not lie flat against the support surface.
- DE 101 07 109 A1 discloses a method for closing the butting opening of rolled bushings with radially outwardly pointing collar.
- the introduction of radially extending recesses in the collar of these bushings displaces material in the circumferential direction, so that the shock opening is closed.
- the rolling process of a bearing bush is not technically related to the Kragen convinced and not transferable to this.
- the Displacement conditions of material in the circumferential direction of the collar would also lead to collars to further wrinkling in the face.
- the collar has a collar, which after pulling the collar by forming the free end of the collar with a radial material displacement, optionally additionally with an axial compression, is formed.
- a groove is formed within the support surface.
- the material that is displaced due to the formation of the groove strengthens the waistband, i. the radially protruding area, and improves the material filling at the "corner" of the collar, i. at the radially outer edge of the front side.
- the corresponding tool has a bead.
- the bead extends at least in sections in the circumferential direction, so that the groove as an impression of the bead within the support surface, i. in the material of the collar in the area of the federal, is formed. The use of the bead avoids potential material overlap when calibrating the collar.
- the invention is preferably used for tilt adjustment of the backrest of vehicle seats in motor vehicles, but can also be used for other purposes.
- FIG. 3 is a schematic representation of a vehicle seat
- Fig. 7 is an enlarged section of Fig. 4 after the formation of the federal government.
- the fitting 10 has a first fitting part 11 and a second fitting part 12, which are rotatable relative to each other.
- the two fitting parts 11 and 12 can each be approximately inscribed in a circular disk shape.
- Both fitting parts 11 and 12 are preferably made of metal, in particular steel, which may be hardened at least partially.
- a Umklamm réellesring 13 is provided. The principle of such a cohesion by means of a Umklamm réellesrings is described for example in US 6,799,806 B2.
- the Umklamm réellesring 13 is preferably made of metal, in particular steel, which is preferably uncured.
- the Umklamm ceremoniessring 13 preferably has a substantially flat ring shape.
- the Umklamm ceremoniessring 13 is fixedly connected to one of the two fitting parts 11 and 12, in the present case the first fitting part 11 in an outer edge section, for example, welded or (at least partially in the circumferential direction) flanged.
- a radially inwardly facing edge of the Umklamm réellesring 13 optionally with the interposition of a separate sliding ring, the relative to him movable, other of the two fitting parts 1 1 and 12 radially outwardly (ie in the radially outer edge region), without the relative rotation of the hamper both fittings 11 and 12.
- the mutually facing inner surfaces of the two fitting parts 11 and 12 are protected from the ingress of foreign bodies and the pollution and damage.
- the Umklamm ceremoniessring 13 and firmly connected with it fitting part 1 1 or 12 so clasp the relative to them movable, other of the two fitting parts 1 1 and 12.
- the two fittings 11 form and 12 therefore together (with the clasp ring 13) a disc-shaped unit.
- the fitting 10 is designed as a geared fitting, in which the first fitting part 11 and the second fitting part 12 are connected by means of a gear for adjusting and locking, more precisely by means of a - present self-locking - eccentric circulation gear, as described for example in DE 44 36 101 A1.
- an externally toothed gear 16 is formed on the second fitting part 12, and an internally toothed ring gear 17 is formed on the first fitting part 11, which meshes with one another.
- the diameter of the top circle of the external toothing of the toothed wheel 16 is smaller by at least one tooth height than the diameter of the root circle of the internal toothing of the ring gear 17.
- a corresponding difference of the number of teeth of toothed wheel 16 and toothed rim 17 of at least one tooth enables a rolling movement of the toothed ring 17 on the toothed wheel 16
- the formation of gear 16 and ring gear 17 is preferably carried out by means of a single embossing-stamping operation, which also punches the fittings 11 and 12 from their starting material.
- the fitting parts 11 and 12 - with similar geometries and the same functions - by massive forming can be produced.
- the gear 16 forms the radially outer edge of the second fitting part 12, ie the second fitting part 12 terminates radially outwardly with the gear 16.
- One of the two fitting parts 1 1 and 12 has a collar 19, in the present case the second fitting part 12 concentric with the gear 16.
- the collar 9 can be formed as a collar on said fitting part (i.e., integrally formed) or attached thereto as a separate sleeve.
- a driver 21 is rotatably supported by a hub 22.
- the driver 21 is preferably made of plastic.
- the hub 22 of the driver 21 is centrally provided with a bore 23 for receiving the drive shaft 7.
- the profile of the bore 23 is matched to the profile of the drive shaft 7, in this case a splined shaft profile formed.
- the driver 21 has an integrally formed with the hub 22 cover plate 25 with a larger diameter than the hub 22.
- the spring 35 acts on the wedge segments 27 in the circumferential direction, in particular to push them apart, wherein in operation the broad sides of the wedge segments 27 can touch and act on each other.
- the driver 21 is axially secured on the outside of the collar 19 having the fitting part by a preferably clipped securing ring 43.
- the securing ring 43 extends in the axial direction along a part of the hub 22, so that the hub 22 does not bear directly on the inside of the collar 19, but is mounted in the collar 19 with the interposition of the securing ring 43 (and thereby the driver 21 on the second fitting part) 12 is stored).
- a sealing ring 44 is provided, for example, made of rubber or soft plastic, which is connected to the cover plate 25, in particular clipped.
- the sealing ring 44 may also be formed of metal and firmly connected to the first fitting part 11, for example welded, be, in which case the cover plate 25 is movable relative to the sealing ring 44.
- a separating ring 45 is optionally provided as an internal seal, which consists for example of plastic.
- Blocking a locking spring 51 is provided, as shown for example in the
- an axial support of the driver 21 is still provided on a support surface 19f of the collar 19.
- the collar 19 has a deviating from a hollow cylinder shape, in particular due to a (radially inwardly facing) collar 19b whose axially facing end face defines the axial support surface 19f of the collar 19.
- the radially inwardly projecting into an inner surface 19i of the base cylinder of the collar 19 in support surface 19f is thereby greater than the average cross-sectional area of the collar 19.
- the driver 21 has a support surface 19f matching contact surface, as in the present case pointing in the axial direction end face of a the hub 22 rounding paragraph is used. In the region of the driver segment 29, this contact surface extends to the radially inner flank of the driver segment 29.
- the collar 19 has the challenge of forming the support surface 19f larger than the average cross-sectional area of the collar 19 and of forming the collar 19b and its support surface 19f radially inwardly beyond the cylindrical inner surface 19i of the collar 19.
- the collar 19 is pulled in a first step, after which the free end 19e of the collar 19 is present in a (radially inwardly facing) funnel shape with decreasing material thickness (FIG. 5).
- a second step FIG. 6
- the free end 19e of the collar 19 with a plurality of tools Wi, W 2 , W ß , W 4 formed, ie in the present case displaced material until the collar 19b is formed (Fig. 7).
- the first tool Wi is axially moved toward the free end 19e, the tool W 2 moves from the opposite direction to the other end of the collar 19, the third tool W 3 moves slightly towards the second fitting part 12, around this still slightly reshape radially outside of the collar 19 and the fourth tool W 4 serves as a stationary holder and counterpart of the third tool W.
- the first tool ⁇ N- ⁇ frontally has an annular bead w, which is formed in the circumferential direction continuously or interrupted, ie at least in sections.
- the bead w is approximately aligned with the radially inner wall (in FIG. 5 the top wall) of the drawn collar 19 and leads in the direction of movement of the tool W ahead.
- the bead w is therefore in the second step shortly before the other, laterally located areas of the first tool W 1 in contact with the material of the free end 9e of the collar 19.
- the material displacement by the bead w improves the formation of the collar 19b, in particular radially inward, wherein the collar 19b is then finally formed by the side of the bead w located areas of the first tool Wi.
- the continuous circumferential groove 19g extends equidistantly to the inner edge of the support surface 19f and has a depth of 0.5mm +/- 0.2mm in the present case. In principle, however, other groove depths are possible; In the figures, a greater depth is shown to illustrate the invention.
- the support surface 19f has in this case an outer diameter of 21mm +/- 1 mm and an inner diameter of 13mm +/- 1mm, wherein the groove 19g is located on a circle with a diameter of 16mm +/- 1mm. Due to the collar 19, the wall thickness of the collar 19 varies over its axial extent. The minimum wall thickness of the collar 19 is 2.7mm +/- 0.5mm.
