Description

The The invention relates to a fitting system for a vehicle seat with the features of the preamble of claim 1.

A fitting system of this kind is from the WO 2009/143999 A1 known. The adjustment fitting has an additional free-pivoting unit, as it is known from transmission fittings with centric free-pivoting. The fitting and the counter fitting are both designed as locking fittings. They are unlocked for tilt adjustment to pivot the backrest in the desired position of use. For free pivoting, the free-pivoting unit and the counter-fitting are unlocked in order to pivot the backrest (obliquely) forward into the freely pivoted position. The set inclination remains stored in the adjustment fitting.

Of the Invention is based on the object, a fitting system of the beginning to improve the type mentioned. This object is achieved by a fitting system with the features of claim 1 solved. Advantageous embodiments are the subject of the dependent claims.

By doing not only the adjustment fitting and the counter fitting as locking fittings are formed, but also the free swing fitting, can all three fittings being fully functional Locking fittings are designed to be taken from series, in which she uses alone for tilt adjustment become. The free-swing fitting is preferably only to that effect modified so that it can only be locked in one or two positions, which, for example, achieved by a free-pivoting control which is a collapse of the bolt in wide angular ranges prevented. So it does not need a special free-wheeling unit be resorted to, as they were otherwise for Fittings of free-swinging backrests is common, but not because of the low quantities is optimizable. All in all, the production costs are thus changed.

The Free-pivoting is a centric free-pivoting, d. H. it takes place around the same axis as the tilt setting. Corresponding the adjustment fitting udn the free-swing fitting offset axially arranged to each other. The two fittings are preferably each connected to one of its two fitting parts. The connection preferably takes place along the adjustment fitting and on the free-swing fitting preferably provided interfaces without modification thereof, for example along the edge similar interfaces or using a suitable molded connecting part. As an interface, a paragraph is preferred which as an axially projecting contour for positive locking Cooperation with the seat part structure part or the backrest structure part is provided, in particular with an opening or other Inclusion in the same.

A such defined interface is for example a star paragraph, which is a multi-armed, substantially symmetrical star shape having. This interface is for different joining methods universally applicable, for example for laser welding with long, possibly interrupted welds and for MAG welding with single short welds. In the training of the star paragraph must - opposite a single ring heel - just a part of the material of the fitting part are issued. Nevertheless arise through the Shape of the star paragraph relatively large distances the attachment points. Opposite several single cone-like Paragraphs decrease in a single star sale on this front side of the fitting the effort in welding, because the welding process does not have to be interrupted several times. In a modified version are only ring heels intended.

With If necessary, a certain orientation of the Fitting part are forced. For this, the exact Symmetry of the star shape (rotational symmetry, mirror symmetry) too be broken by a deviation in their dimensions is small compared to the star shape and the as (additional) Positioning aid or anti-twist device is used. Especially advantageous is the star heel in Rastbeschläge also fourfold Symmetry.

to Limitation of the angle ranges of the inclination adjustment and the free pivoting are preferably corresponding radially and / or axially projecting Stops on the fittings, Umklammerungsringen, Sitzteilstrukturteile or backrest structural parts provided.

in the The following is the invention with reference to an illustrated in the drawing Embodiment explained in more detail. Show it

8th a schematic representation of a vehicle seat.

A vehicle seat 1 for a two-door or three-door motor vehicle has a seat part 3 and a relative to the seat part 3 tilt-adjustable backrest 4 on. For tilt adjustment of the backrest 4 becomes a first actuator 5 , In this case, a hand lever in the transition region between the seat part 3 and lean 4 , manually operated. In the present case, the first actuating element rotates 5 a transmission rod 7 , which are horizontal in the transition area between seat part 3 and lean 4 is arranged. For additionally provided free pivoting of the backrest 4 becomes a second actuator 8th , in this case a hand lever on the side of the backrest 4 , manually operated.

The tilt adjustment and the free pivoting takes place by means of a fitting system 10 , The fitting system 10 has a vehicle seat side assembly with an adjustment fitting 10a and a free swing fitting 10b and on the other vehicle seat side a counter fitting 10c on. The three fittings 10a . 10b . 10c are largely the same education.

Each of the three fittings 10a . 10b . 10c has a first fitting part 11 and a second fitting part 12 on which are rotatable relative to each other about an axis A. The (imaginary) axis A is aligned in this case with the transmission rod 7 , The two fitting parts 11 and 12 let each inscribe approximately in a circular disc shape. Both fitting parts 11 and 12 are preferably made of metal, in particular steel, which may be cured at least partially. For receiving the axially acting forces, ie for the axial cohesion of the fitting parts 11 and 12 , is a clasp ring 13 intended. The clasp ring 13 is preferably made of metal, in particular steel, which is preferably uncured. The clasp ring 13 preferably has a substantially flat ring shape, but can be profiled in an alternative design L-shaped with a cylinder portion and the front side a flat ring portion.

The clasp ring 13 is fixed with one of the two fitting parts 11 and 12 connected, in this case in an outer ring portion with the second fitting part 12 , For example by means of laser welding or by means of another known fastening technique. By means of an inner ring portion, which is arranged in a direction perpendicular to the axial direction plane, overlaps the Umklammerungsring 13 , optionally with the interposition of a sliding ring, the first fitting part 11 in the radially outer edge region, without the relative movement of the two fitting parts 11 and 12 to hinder. In addition, the mutually facing inner surfaces of the two fitting parts 11 and 12 protected against the ingress of foreign bodies and the pollution and damage.

The clasp ring 13 and the fitting part fixed to it 11 or 12 so clasp the relative to them movable, other of the two fittings 11 and 12 , In terms of construction, the two fitting parts 11 and 12 therefore together (with the clasp ring 13 ) a disc-shaped unit.

With the assembly of the assembly from adjustment fitting 10a and free swing fitting 10b is one of the two fitting parts 11 or 12 of the adjustment fitting 10a , in the present case the first fitting part 11 , preferably firmly with one of the two fitting parts 11 or 12 of the free-swinging fitting 10b , in the present case the first fitting part 11 , connected. The other two fittings 12 are then fixed to the structure of the seat part 3 ie a seat part structure part 3a , or the structure of the backrest 4 ie a backrest structure part 4a , connected, so Sitzteilfest or leaning. In the present case, the second fitting part of the adjustment fitting 10a Sitzteilfest, while the second Beschgteil 12 of the free-swinging fitting 10b is leaning. The adjustment fitting 10a and the free-swing fitting 10b lie in the power flow between backrest 4 and seat part 3 , in series with each other.

Accordingly, the counterfitting 10c on the other side of the vehicle seat one of the two fitting parts 11 or 12 firmly with the structure of the seat part 3 ie a seat part structure part 3a , and the other stuck with the structure of the backrest 4 ie a backrest structure part 4a , connected, so Sitzteilfest or leaning. The counterfitting 10c lies in the power flow between backrest 4 and seat part 3 , and parallel to the assembly of fitting fitting 10a and free swing fitting 10b ,

For a defined interface of the fittings 10a . 10b . 10c to the structures of seat part 3 or leaning 4 or to each other or to another counterpart are on the two fittings 11 and 12 axially projecting contours see which form fit with corresponding receptacles in the counterpart, for example, a seat part structure part 3a , a backrest structure part 4a or an adapter, can work together. The thus pre-positioned fitting 10a . 10b . 10c can then be attached to the respective structural part, for example by laser welding or MAG welding.

The present is on the first fitting part 11 - on his second fitting part 12 opposite end face - a circular ring shoulder 11a formed, for example, by a material exhibition when embossing the first fitting part 11 , In the case of the counter fitting 10c grips the ring heel 11a positively in a circular, continuous recording in the local seat part structure part 3a or backrest structure part 4a so that the seat part structure part 3a or backrest structure part 4a in the radially outside of the annular shoulder 11a arranged part of the front side of the first fitting part 11 in contact with the first fitting part 11 the counter fitting 10c comes. Along the outer edge of the ring heel 11a (In this case at the same time along the edge of the recording) is then attached a weld. In the case of laser welding, the weld around the annular course of the outer edge of the annular shoulder 11a the counter fitting 10c commute.

At the second fitting part 12 is present - on his from the first fitting part 11 opposite end face - a star heel 12a educated. The star heel 12a has a multi-armed, substantially symmetrical star shape (in this case a four-armed cross). The substantially symmetrical star shape may be exactly symmetrical or have a deviation therefrom, the dimension of which is small compared to the (radial) dimensions of the star heel 12a is, and by means of which (in addition to the star shape) a positioning aid or rotation is provided, which forces the positive connection with the counterpart in exactly one possible orientation. At the present Sternabsatz 12a Each arm closes with a convex arc (and a straight piece), and the arms tangentially overlap each other with a concave arc (and a straight piece). Preference is given to circular arcs, that is to say with constant curvature, but also other arcs, in particular trigonometric arcs, are conceivable. In the middle of the star paragraph 12a In the present case, an additional exhibition is planned for reasons of space.

The star heel 12a engages positively in a precisely fitting, continuous receptacle in the seat part structure part 3a or the backrest structure part 4a so that the seat part structure part 3a or backrest structure part 4a in the radially outside of the star heel 12a arranged part of the front side of the second fitting part 12 in contact with the second fitting part 12 comes. Along the outer edge of the star heel 12a (In this case at the same time along the edge of the recording) is then attached a weld. In the case of laser welding, this weld may be around the outside edge of the star landing 12a commute. For example, in the case of MAG welding, a short weld is provided at the end of each arm.

All three fittings 10a . 10b . 10c are each designed as latching fitting, in which the first fitting part 11 and the second fitting part 12 Lockable with each other, as for example in the DE 10 2006 015 560 B3 is described, the relevant disclosure of which is expressly incorporated.

The second fitting part 12 has - in the present case four - guide segments 14 on which with straight guide surfaces in pairs one bar each 16 lead laterally in the radial direction. The - in this case four - bar 16 are - in this case by 90 ° - offset from each other in one between the two fitting parts 11 and 12 arranged space arranged. The bars 16 are provided at their radially outer end with a toothing, which with a sprocket 17 designed as a ring gear first fitting part 11 can engage. When the sprocket 17 and the bolts 16 interact, is the free swing fitting 10b locked.

The first fitting part 11 is in a recess of the second fitting part 12 arranged and is overlapped by this radially outside, whereby the two fitting parts 11 and 12 store each other. In this case, the radially outer edge region of the first fitting part 11 with the sprocket 17 in the radial direction between the guide segments 14 and the (the storage of the first fitting part 11 serving) radially outer edge region of the second fitting part 12 arranged. At high loads, for example in the event of a crash, the first fitting part 11 - after deformation - with his sprocket 17 in contact with the guide segments located nearer in the load direction 14 come, which towards the sprocket 17 correspondingly (concentrically) have curved surfaces. This increases the strength of the relevant fitting 10a . 10b . 10c ,

The first fitting part 11 can in the second fitting part 12 be stored. However, the conditions could be exactly the opposite, ie the second fitting part 12 can on the first fitting part 11 be stored. Basically, however, both arrangements are equivalent.

In the center of the fitting 10a . 10b . 10c is a driver 21 arranged, for example made of plastic, which rotatably on at least one of the two fitting parts 11 and 12 , in this case the first fitting part 11 , is stored, more precisely in a central opening thereof. On the driver 21 sits non-rotatably or at least coupled to driving an eccentric 27 which is in between the fitting parts 11 and 12 is arranged defined space. A spring arrangement 35 , For example, one or two nested coil springs, is in a central receptacle of the two fitting parts 11 and 12 , in this case the second fitting part 12 , arranged and externally supported in the present case. The spring arrangement 35 acts on the eccentric 27 In this case, by turning inwards on the driver 21 sitting. Such a spring arrangement 35 is for example in the DE 10 2005 046 807 B3 described, the related disclosure of which is expressly incorporated. The one of the spring arrangement 35 acted eccentric 27 acts on the radially movable latch 16 and urges them so that they are pressed radially outward to enter the sprocket 17 to invade, whereby the fitting 10a . 10b . 10c is locked.

A control disc 36 is in the space between the bars axially 16 and the first fitting part 11 arranged and sits in the present rotation on the eccentric 27 , The control disc 36 has - in the present case four - control tracks, each with a nose 38 every tie 16 interact. The noses 38 stand in the axial direction of their assigned bars 16 from. With a turn (by a few degrees) of the driver 21 - And the driven eccentric 27 and the control disc 36 - Against the force of the spring arrangement 35 pulls the control disc 36 the bars 16 radially inward, ie from the sprocket 17 , with which the fitting 10a . 10b . 10c unlocked and the two fitting parts 11 and 12 relative to each other about the axis A, so in this case the drive shaft 7 , are rotatable. The rest 4 is thereby pivotable about the axis A, in the case of the adjusting fitting 10a in another position of use and in the case of the free-swinging fitting 10b forward in a freely pivoted position to facilitate access to the next row of seats, and then back to the previously occupied position of use.

It increases the ease of use when the hand lever 8th after unlocking the free-swing fitting 10b does not have to be held during the entire free pivoting and the free swing fitting 10b can optionally lock in the freely pivoted position. In the free swing fitting 10b (and optionally in counterfitting 10c ) is between the control disc 36 and the first fitting part 11 around the axis A optionally an annular free-pivoting control 45 provided, which rotatably with the first fitting part 11 connected is. The free-wheeling control 45 has stop lines, with the noses 38 the latch 16 cooperate by limiting their movement radially outward or let them unimpeded. To the back 4 over more than the angle between two bars 16 to be able to swing freely are the noses 38 the latch 16 alternately different radially outward or radially inward on the bars assigned to them 16 arranged so that adjacent noses 38 interact with different stop tracks. Accordingly, two different configurations of the bars 16 intended. Details are in the DE 10 2006 015 560 B3 described.

The assembly from adjustment fitting 10a and free swing fitting 10b is connected by the fact that the first fitting part 11 of the adjustment fitting 10a and the first fitting part 11 of the free-swinging fitting 10b are firmly connected to each other, preferably directly attached to each other by the annular heels 11a abut each other and are firmly connected to each other by means of a circumferential weld, preferably a laser weld. Optionally, there is a spacer ring 205 between both ring heels 11a inserted and firmly connected to this, in order to achieve a certain outer dimension of the assembly in the axial direction (ie in the direction of the axis A).

With the first two fittings 11 of the adjustment fitting 10a and the free-swing fitting 10b is a first stop segment 210 firmly connected, which formed for example as part of a ring and the welded fitting parts 11 is welded. The first stop segment 210 has at least one, preferably two radially projecting stop lugs 210n on. The stop noses 210n limit the angle range for the tilt setting by locking with a stopper 215 interact. The lock stop 215 is Sitzteilfest, in this case by the fitting on the fitting 10a attached seat part structure part 3a protrudes axially. This can be the catch stop 215 on the seat part structure part 3a be formed, such as in the DE 20 2009 015 235 U1 described, or separately formed and the seat part structure part 3a be attached.

To limit the angle range for the free-pivoting, the stop lugs 210n with a second stop segment 218 interact, which at the free swing fitting 10b provided and fixed to the backrest structure part 4a connected is. In the present case, the second stop segment runs 218 along a part of the circumference of the first fitting part 11 and is at this (and at the same time at the encircling ring 13 ), before preferably welded. The second stop segment 218 has two stop fingers 218f on which project axially and into the plane of the first stop segment 210 rich, leaving them with the stop noses 210n can interact.

The function of the fitting system 10 is exemplary in the WO 2009/143999 A1 described. By actuation of the first actuating element 5 becomes the transmission rod 7 turned. The transmission rod 7 is the driver 21 of the adjustment fitting 10a and counter fittings 10c recorded, in the present case coupled by means of a splined shaft profile on driving. The rotation of the drivers 21 of the adjustment fitting 10a and counter fittings 10c due to the rotation of the transmission rod 7 causes, therefore, that the fitting fitting 10a and the counterfitting 10c Unlock. The rest 4 can be swiveled until the desired position of use is reached. By releasing the first actuating element 5 take care of the spring arrangements 35 of the adjustment fitting 10a and counter fittings 10c for that the adjustment fitting 10a and the counterfitting 10c lock again.

Preferably, each of the fittings 10a . 10b . 10c is at one end of the driver 21 , present to the one at the second fitting part 12 , a fastening ring 224 provided, which in the present case consists of plastic and by means of ultrasonic welding on the driver 21 is attached. An operating lever 225 , For example, plastic, is rotationally fixed to the driver 21 of the free-swinging fitting 10b connected. In the present case is the operating lever 225 on the fastening ring 224 fastened, namely clipped, with form-fitting cooperating contours for the connection in the circumferential direction (and radial direction) and the mutually verclipsten material parts provide for the connection in the axial direction. The on the inside of the backrest structure part 4a arranged actuating lever 225 is in operative connection with the second actuating element 8th , for example by means of a Bowden cable. The operating lever 225 of the free-swinging fitting 10b (or the second actuator 8th ) is, for example by means of another Bowden cable, in operative connection with a corresponding actuating lever, the rotationally fixed to the driver 21 the counter fitting 10c connected. To the drivers 21 the free-swing fitting 10b and counter fittings 10c with the operating levers 225 To connect better, these two drivers 21 preferably slightly different to the driver 21 of the adjustment fitting 10a educated.

Between the transmission rod 7 and the driver 21 the counter fitting 10c In one direction of rotation, a free path ("decoupling angle") is provided, ie in the initial position, the longitudinal ribs of the splined shaft profile in the hub receptacle of the driver 21 over a certain angle - in the present case about 30 ° - spaced apart. The free travel is greater than that for unlocking the counter fitting 10c necessary Entriegelungsweg the driver 21 , In the other direction of rotation no free travel is provided in the starting position. An actuation of the second actuating element 8th pivots the operating lever 225 of the free-swinging fitting 10b and those of the counter fitting 10c so that the respective driver 21 to be turned around. The free swing fitting 10b and the counterfitting 10c unlock it. The rest 4 can now be swiveled into the freely pivoted position, where it is optionally secured. The set backrest inclination remains in the adjustment fitting 10a saved. If the backrest 4 is pivoted back, the free-swing fitting lock 10b and the counterfitting 10c upon reaching the previously occupied position of use.
