Definitions
- the invention relates to a fitting for a vehicle seat with the features of the preamble of claim 1.
- the invention is based on the object to provide a fitting of the type mentioned with an alternative gearing. This object is achieved by a fitting with the features of claim 1.
- Advantageous embodiments are the subject of the dependent claims.
- a constant radius of curvature represents a simple geometry that is easy to manufacture and to design for different variants. Preferred geometrical relations of the rolling point, the centers of gear and ring gear and a Momentanpol improve the properties of this gearing.
- the use of a Exzenterumlaufgetriebes in a fitting allows a stepless inclination adjustment of the back of a vehicle seat.
- the saving of a central pinion in relation to a planetary planetary gearbox leads to the formation of a ner tumbling motion, which is superimposed on the relative rotation of the fitting parts.
- the eccentric which consists, for example, of two wedge segments stretched apart by a spring or of a crescent-shaped element, is preferably mounted on its side opposite the sliding bearing, for example the inside, on a collar of the other fitting part.
- Fig. 2 is an axial section through the embodiment
- Fig. 3 is an exploded view of the fitting
- Fig. 4 is a schematic representation of a vehicle seat.
- a vehicle seat 1 for a motor vehicle has a seat part 3 and a backrest 4 that is adjustable in its inclination relative to the seat part 3.
- a drive shaft 7 is rotated manually, for example by means of a hand wheel 5, or motor, for example by means of an electric motor, which is arranged horizontally in the transition region between the seat part 3 and backrest 4.
- the drive shaft 7 rotatably engages in a fitting 10 in a manner described later.
- the drive shaft 7 defines the used directional information of a cylindrical coordinate system.
- the fitting 10 is designed as a geared fitting, in which a first fitting part 1 1 and a second fitting part 12 are connected to each other by means of a gear for adjusting and locking, more precisely by means of a - present self-locking - eccentric orbit gear, as for example in the DE 44 36 101 Al is described, the relevant disclosure of which is expressly incorporated.
- the first fitting part 11 for example, firmly connected to the structure of the backrest 4, so lean backrest.
- the second fitting part 12 is then firmly connected to the structure of the seat part 3, so fixed seat.
- These assignments of the fittings 1 1 and 12 are preferred when the drive shaft 7 and the backrest 4 should have the same direction of rotation, or if the position of the drive shaft 7 with respect to the backrest 4 should be constant, for example, a drive shaft 7 rotating electric motor on the Structure of the back 4 to attach.
- the assignments of the fittings 1 1 and 12 may also be reversed, i.
- the first fitting part 11 would then be fixed to the seat part and the second fitting part 12 leaning against.
- the latter assignments of the fitting parts 1 1 and 12 are preferred when the radial distances of the attachment points between the fitting 10 and a relatively thin backrest sheet should be as large as possible.
- the two fitting parts 11 and 12 can each be approximately inscribed in a circular disk shape.
- the two fitting parts 1 1 and 12 are preferably made of metal, especially steel.
- a Umklamm réellesring 13 is provided to accommodate the axially acting forces, ie the cohesion of the fitting parts 11 and 12.
- a Umklamm réellesring 13 is provided to accommodate the axially acting forces, ie the cohesion of the fitting parts 11 and 12.
- a Umklamm réellesring 13 is provided to accommodate the axially acting forces, ie the cohesion of the fitting parts 11 and 12, a Umklammitzsring 13 is provided. Such a cohesion by means of a Umklamm réellesrings is described for example in US 6,799,806 A, the relevant disclosure of which is expressly incorporated.
- the preferably metallic Umklamm réellesring 13 is connected to the assembly of the fitting 10 fixed to the second fitting part 12, preferably first pressed and then welded. Alternatively, the Umklamm réellesring 13 is
- the Umklamm ceremoniessring 13 On one of its end faces, the Umklamm ceremoniessring 13 has a radially inwardly bent edge, by means of which he, optionally with the interposition of a sliding ring, the first fitting part 11 radially overlaps externally, without hindering the relative movement of the two fitting parts 11 and 12. In terms of construction, the two fitting parts 1 1 and 12 therefore together form a disc-shaped unit.
- 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 tip circle of the external toothing of the toothed wheel 16 is smaller by at least one tooth height (of the ring gear 17) than the diameter of the root circle of the internal toothing of the toothed ring 17.
- a corresponding difference in the number of teeth of toothed wheel 16 and toothed rim 17 of at least one tooth enables a rolling movement of the teeth Sprocket 17 on the gear 16.
- the first fitting part 11 has, on the side facing the toothed wheel 16, concentric with the ring gear 17 a collar 19, which may be formed as a collar on the first fitting part 1 1 (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.
- two wedge segments 27 are supported (with their curved inner surfaces), which store (with their curved outer surfaces) the second fitting part 12 by means of a plain bearing bush 28 which is pressed in rotation in the second fitting part 12.
- the driver 21 has - radially spaced from the hub 22 - with a game between the narrow sides of the wedge segments 27 grasping driver segment 29, which is formed integrally with the cover plate 25 and the hub 22.
- the mutually facing broad sides of the wedge segments 27 each take a defined by projecting material parts recess each an angled end finger of an omega spring 35 which pushes apart the wedge segments 27 in the circumferential direction, wherein in operation, the protruding material parts of the wedge segments 27 can touch and act on each other.
- the driver 21 is axially secured on the outside of the first fitting part 11 by a clip-on circlip 43.
- a sealing ring 44 is provided between its radially outer edge and the cover plate 25, for example made of rubber or soft plastic, which is connected to the cover plate 25, in particular clipped.
- an eccentric which presses the gear 16 at a so defined engagement point in the ring gear 17 in extension of the direction of eccentricity.
- a torque is first transmitted to the driver 21 and then by means of the driver segment 29 on the eccentric, which slides along the plain bearing bush 28 with displacement of the direction of eccentricity and thus under displacement of the intervention agency of the gear 16th in the ring gear 17, which is a tumbling rolling motion, ie as relative rotation with superimposed wobble.
- the inclination of the backrest 4 is thereby continuously adjustable between several positions of use.
- the eccentric i.e., the wedge segments 27
- the eccentric is supported by the second fitting part 12, while in turn supporting the first fitting part 11, or the conditions are exactly the opposite, that is. the eccentric is supported on the first fitting part 11 and supports the second fitting part 12.
- Each of the - in this case thirty-three - teeth 16a of the gear 16 has radially inwardly on both sides a tooth root 16b, radially outwardly a tooth tip 16c and between each side a tooth flank 16d.
- the head circle circumscribing the tooth tips 16c and the root circle inscribed by the tooth roots 16b are concentric with the eccentric bushing 28 lined with the slide bearing bushing 28, thereby defining a center M 16 and a radial direction (in cylindrical coordinates) of the gear 16.
- the course of two adjacent toothed feet 16b results, for example, from a radius of about 1 mm (quarter circle) adjoining one tooth flank 16d (continuous and differentiable), a straight piece tangentially adjoining the root circle of 1 to 2 mm and a mirror-symmetrical radius of approximately 1 mm (quarter circle), which adjoins the next tooth edge 16d.
- the tooth roots 16b merge into one another at the point of contact with the root circle (radius, for example, about 31 mm).
- the course of a tooth head 16c results, for example, from a radius of about 1 mm (quarter circle) adjoining one tooth flank 16d (continuous and differentiable), a tangential piece of 1 to 2 mm and a mirror-symmetrical radius of about 1 mm (quarter circle), which connects to the other tooth edge 16d.
- the tooth tips 16c touch the tip circle (radius, for example, about 34 mm) at its radially outermost location.
- each of the - in the present case thirty-four - teeth 17a of the toothed rim 17 has a tooth root 17b, a tooth head 17c and two tooth flanks 17d.
- the tip circle inscribed by the tooth tips 17c and the root circle circumscribing the tooth roots 17b are concentric with the collar 19 in the present case, thereby defining a center Mn and a radial direction (in cylindrical coordinates) of the ring gear 17.
- the courses of the tooth roots 17b and the teeth heads 17c preferably correspond to those of the tooth roots 16b and tooth tips 16c.
- the at the root circle (radius, for example, about 36 mm) fitting straight piece can be slightly longer than that at the gear 16.
- the radius on the tooth head 17c may be slightly greater than that on the tooth head 16c, whereby the piece resting against the tip circle (radius, for example, about 33 mm) becomes somewhat shorter than with the toothed wheel 16.
- the tooth roots 17b of adjacent teeth 17a merge with each other at the point of contact (their radially outermost point) with the root circle, thus defining the tooth base enclosed by them.
- the tooth tips 17c touch the tip circle at their radially innermost location.
- the eccentricity e (of the eccentric) is the distance between the center M 17 of the ring gear 17 and the center Mi 6 of the gear 16. It is for example 1 to 2 mm.
- the exact configuration of the teeth 16a and 17a shows how the teeth 16a, 17a can come into contact, in particular at which contact lines and surfaces.
- a pitch point W - in system so serve the rolling movement, while the tooth tips 16c, 17c and the tooth roots 16b, 17b thereof can be configured independently.
- the pitch point W is not exactly in extension of the eccentricity e, but is - with respect to the center Mi ⁇ of the gear 16 - at a first angle ⁇ of 10 ° to 50 °, in particular approximately 45 ° , about the extension of the eccentricity e.
- the system of these tooth flanks 16d and 17d acts in the pitch point W as if gear 16 and ring gear 17 would rotate relative to each other about a Momentanpol P.
- the first angle ⁇ depends on the shape of the wedge segments 27, in particular of the wedge angle, and their position during the rolling movement.
- e occurs on the opposite side of the rolling point W a further pitch point, so that the gear 16 is supported at three points (eccentric and the two rolling points), that is stabilized.
- the instantaneous pole P lies in each case in extension of the eccentricity e.
- the tooth flanks 16d and 17d are are formed as circular arc pieces around the instantaneous pole P, ie their center of curvature is the same point, namely the instantaneous pole P, and the (constant) radius of curvature Ki of the tooth flank 16d and the (constant) radius of curvature K 2 of the tooth flank 17d are also the same (for example about 33 mm ).
- the same radius of curvature Ki K 2 for the tooth flanks 16d and 17d is an ideal radius of curvature for perfectly machined teeth 16a and 17a.
- the actual radius of curvature K 2 of the tooth flank 17d is slightly smaller and / or the actual radius of curvature Ki of the tooth flank 16d is slightly larger than the ideal radius of curvature, so the radius of curvature Ki of the tooth flank 16d at the pitch point W and the radius of curvature K 2, the tooth flank 17d at the pitch point W is (only) at least approximately equal.
- both centers of curvature lie on the connecting straight line between the pitch point W and the instantaneous pole P.
