Description

The Invention relates to a fitting arrangement for a seat, in particular for a vehicle seat and a method for mounting a fitting arrangement.

A Fitting arrangement for a seat, in particular for a motor vehicle seat usually comprises two fittings, which are each arranged laterally on the seat and on the each a seat member is connected to a backrest element such that a tilt adjustment of the backrest element allows is. Are the fittings as so-called snap fittings trained, so the fittings for tilt adjustment from a closed or latched position to a release position to be brought.

The locking fittings usually have two fitting parts, which are mechanically fastened to the backrest element and the other on the seat member and rotatably supported against each other. For locking in the closed position usually locking elements are provided. These are for example mounted displaceably in the radial direction on the one fitting part and are moved against the second fitting part in a locking position. In the locked position, for example, teeth of the locking elements and of the second fitting part engage in one another. To unlock the locking elements are retracted in the radial direction, so that the teeth come out of engagement and a rotational movement of the two fitting parts to each other and thus a tilt adjustment is possible. This unlocking is effected for example by a side mounted on the seat actuating lever. Such a catch fitting is for example from the EP 1 066 170 B2 refer to.

For the operation of the adjustable locking elements is usually provided a drive element, for example, a cam with eccentrically arranged cams and on a shaft is arranged rotationally fixed. The shaft is over the operating lever twisted. Due to the eccentric arrangement of the cam is a Actuation of the bolt in or out of its closed position.

at a motor vehicle, the operating lever is regular arranged on the outside on the door side. At the opposite to the respective adjacent seat (driver's seat or passenger seat) oriented side, the so-called tunnel side, is therefore only a fitting without operating lever arranged. Overall, therefore, in a motor vehicle four different Fittings required, resulting in a relatively large Expenditure in warehousing and provision during assembly leads.

Out safety considerations must be at a Vehicle seat also ensures that the two Locking fittings are mounted largely synchronously with each other, d. H. that they are in a defined position of the wave in an identical Closing or release position are arranged. simultaneously but should also be the lever of comfort and Design reasons oriented in a defined angular position be. Due to this requirement, the assembly of such Fitting arrangement associated with comparatively great effort.

Of the Invention is the object of the effort for the Assembly of such a fitting arrangement in fulfillment to simplify the requirements.

The Task is solved by a fitting arrangement with the Features of claim 1.

The fitting arrangement has a first and a second fitting, in particular latching fittings, which each comprise a first, tunnel-side, and a second, door-side drive element. In this case, the drive elements are preferably designed as cam disks with eccentric cams or comprise at least one such cam disk. The drive elements are generally used for adjusting a locking element of the detent fitting. The drive elements each have a recess with an inner contour. Furthermore, the fitting arrangement comprises a shaft connecting the two fittings, which is designed in particular as a hollow shaft, and an adjusting element which serves for the actuation (unlocking) of the fittings. The shaft has a first, tunnel-side end with an outer contour for positive insertion into the first, tunnel-side drive element and a second, door-side end. This is formed substantially cylindrical. Of particular importance here is that the shaft with the tunnel-side end is positively inserted and thus rotationally fixed in the first drive element. At the same time, the shaft with its second cylindrical end is initially not connected in a rotationally fixed manner to the second drive element. The door-side end is deviating from the tunnel-side end is not designed for positive insertion into the drive element, thus has no adapted to the inner contour outer contour. This special embodiment makes it possible that in an intermediate mounting position, the door-side drive element, the door-side end of the shaft and the adjusting element are initially positioned in any rotational position to each other, so can be rotated relative to each other, so that these three components, in particular the adjustment in the desired rotational position are oriented. Finally, means for fixing these ge desired and set rotational position between the shaft, the door-side drive element and the adjustment provided, so that in a final assembly position, the two drive elements, the shaft and the adjustment are rotatably connected to each other. The rotational position of the shaft is determined here by the positive connection on the side of the first drive element.

Of the particular advantage of this arrangement is the fact that the both fittings, so both the tunnel side and the door-side fitting, an at least largely identical Structure may have. Only with the assembly takes place Determining for which seat and for which side of the respective seat of the fitting is used. Because of this Common parts principle are therefore the storage and disposition Material flow to final assembly significantly simplified.

By the free relative rotation of the shaft with respect to the door side Drive element is guaranteed that this at the Assembly is not rotated from its defined position. Stay that way during assembly, the two drive elements of the two fittings in a defined, uniform position. This defined position the drive elements, for example, when assembling the fittings and is preferably the closed position of Forged. This is a total of synchronization the position of the drive elements and thus the closed position the locking fittings ensured.

By the free relative rotational movement of the adjustment can also also this be brought into the desired rotational position, before it is firmly connected to the shaft and the drive element.

in the Meaning of the common part principle are according to a expedient embodiment, the recesses of the drive elements, into which the shaft is inserted with your differently shaped ends, formed identical, so have the identical inner contour. In particular, the drive elements are all or the cams identically formed.

For the embodiment of the positive plug-in connection on the tunnel side, the inner contour of the drive elements is in a preferred embodiment out of round and in particular by type a polygon formed. Under polygon is general here understood a design, as in so-called inner polygonal screws is known. The recess may in this case have a polygonal cross-sectional area, for example, a triangular, quadrangular or hexagonal cross-sectional area exhibit. Under polygonal design is in particular an embodiment considered, in which the recess starting from a preferably Circular geometry circumferentially discrete individual, for example rectangular or trapezoidal pockets or Has bulges.

According to one expedient development is on one of the two fitting pages an axial securing provided for the shaft, the axial slipping prevents the shaft. This is preferably on the door side and in particular automatically by the non-rotatable connection between formed of the shaft, the second drive element and the adjusting element. On the opposite side of the tunnel is preferably no axial lock provided. Rather, it is at this point the shaft with its tunnel-side end with some axial play, So loose, in the tunnel-side drive element. As far as that is on the tunnel side for the shaft a floating bearing and up the door side formed a fixed bearing.

In In a preferred embodiment, the adjusting element is a Adapter pin formed, which in turn for the arrangement an actuating lever is formed. about the operating lever is the manual operation with the hand of the user. The adapter bolt therefore represents a model or customized interface and defines the connection option for a respective model or custom operating lever. Only by the adapter bolt is a customer-specific adaptation. This therefore allows for the most diverse Models the identical fittings in the sense of a To use identical parts principle. The adapter bolt is preferably an axially extending bolt-shaped Element, with its one end in the second drive element is inserted and its second end in the axial direction of the fitting protrudes and serves for mounting the operating lever. This For example, it is attached to the adapter pin in a rotationally fixed manner. the purpose of this formed at its second end in the manner of a polygon is.

As a means for fixing the rotational position between the shaft, the drive element and the adjusting element, a form-fitting press or press-fit connection between at least two of these three components is provided according to a preferred embodiment. The determination of the desired rotational position is therefore carried out in a simple manner by a press-fit, in particular without further fasteners are required. During the press-in operation, a desired plastic deformation of the material takes place here, for example by protruding anti-rotation elements, such as noses, teeth, etc. By means of the press-in connection, an axial securing by frictional engagement is achieved at the same time. During assembly, this is done that the individual parts are brought to one another in the desired rotational position, without that they are already firmly connected to each other. Subsequently, the parts in the axial direction, ie in the longitudinal direction of the shaft, are driven into one another and thus rotatably connected to each other in the previously set desired rotational position. According to an expedient embodiment, it is provided that at least one of the components has a particular circumferential knurling or toothing.

Preferably The means for fixation comprise alternatively or additionally a socket which is form-fitting in the recess of the second Drive element rests. The socket defines this particular an assembly aid for the adjustment and the shaft, the with the second drive element respectively indirectly over the socket are rotatably connected. Through the socket is total improved stability achieved because the adjustment and / or the shaft are plugged into the socket. This is also true an increased security against so-called abuse forces given when, for example, a user the operating lever abused as a step. To form the positive connection of Bushing with the recess of the drive element has the socket end designed a complementary to the recess Outer contour, in particular polygonal contour, on.

Conveniently, the bush is pressed into the recess, d. H. the socket is free of play in the recess, so that it is fixed in the axial direction is. During assembly, the procedure is such that initially the bush is pressed into the recess, then brought the shaft and the adjusting element in its desired rotational position and finally connected to the sleeve rotatably. For this purpose, the shaft and / or the adjustment by Press in to be connected to the socket.

alternative or in addition to pressing in is in a preferred Variant for fixing the rotational position a cohesive Connection, in particular a welded joint provided. About the Welded joint can be both a rotation lock as well an axial securing can be achieved. Depending on the configuration here the socket with the drive element, the socket with the adjusting element, the bushing with the shaft, the shaft with the adjusting element or also in a common weld the socket be connected to the shaft and the adjusting element. In principle exists also the possibility of adjusting and / or the To weld the shaft directly to the drive element. The Welded connection is preferably exclusively on the accessible side of the door and over the socket on the outside.

In expedient embodiment, the socket on the outside preferably in several areas Materialverjüngungen on, so that sweat pockets are formed. These sweat bags define desired welding positions and ensure a secure welding. The sweat pockets run preferably in the axial direction and are around the shell side of the sleeve arranged evenly distributed. additional or alternatively, a circumferential weld be provided.

alternative to the embodiment with the pressed bush this is with Game and thus loose in the axial direction in the recess such that possibly occurring axial forces are not transmitted to the drive element become.

According to one preferred embodiment, the socket and preferably also the shaft each have an outer stop, over the axial position is fixed with respect to the second fitting. With this outer stop, for example, as a peripheral Ring collar is formed, supports both the shaft as well as the socket in each case on a fitting part of the door side Fog off.

Around a high mechanical resistance especially against abuse To reach, the components shaft, adjustment and socket in the manner of a tube-in-tube combination plugged into each other. Especially is here provided that, for example, in the region of a weld all three elements are inserted into each other.

Conveniently, is provided here that the adjusting element with two pins having different diameter, the end in the axial direction connect to each other. The front pin with a smaller one Diameter is here in the form of a hollow shaft shaft plugged in. The outer diameter of this front pin is adapted to the inner diameter of the hollow shaft, so that at most an introductory game is given. The rear pin is in contrast formed with a larger diameter, which at the inner diameter of the socket if necessary with a Einführspiel is adjusted. This will be a particularly stable connection achieved. At the same time, the rear pin defines a stop for the wave. Preferably, the adjusting element has an additional particular designed as a ring collar outside stop on, with which is the adjusting element at the front end of the socket supported.

As an alternative to this two-stage pin configuration, the adjusting element and the shaft are inserted into the socket and are quasi aligned with each other. Both the shaft and the inserted pin of the adjustment are in this case directly cohesively with the bushing preferably connected by welding.

According to one third embodiment is finally provided that the adjusting element has a long pin which passes through the entire socket is inserted through. At the end is the wave attached, which therefore only indirectly via the long pin is connected to the socket and the drive element. The attachment The shaft on the long pin can either cohesively or by pressing.

The Task is further solved according to the invention by the method for assembling a fitting arrangement according to claim 16th

The with regard to the fitting arrangement mentioned advantages and preferred embodiments are mutatis mutandis to transfer to the procedure. To a defined synchronization between the two fittings to ensure the fittings are preferably in at the beginning of assembly a defined closed position. In this are the driving elements in a defined rotational position in which the locking elements themselves in the blocking position, for example in its radially outer Position, allowing a rotational movement of the two fitting parts prevented each other. The locking fittings are so delivered pre-assembled in this closed position and on Seat attached.

The Task is also a fitting arrangement with the features of claim 18 solved.

Accordingly, a fitting arrangement for a seat, in particular for a vehicle seat, comprises

• A first fitting having a first drive element,
• A second fitting having a second drive element,
• A shaft connecting the first and the second fitting and extending along an axis of rotation, which has a first end which is connected in a form-fitting manner to the first drive element and a second end which is connected to the second drive element,
• - An adjustment for actuating the fittings and
• - A socket which rotatably connects the second end of the shaft, the second drive element and the adjusting element to each other and to a material connection has.

this the idea is based on the connection of the fittings interconnecting shaft with the drive element of the second To produce fittings and the adjustment via a socket, For example, the form-fitting manner in a recess of the second drive element can be plugged in and at least a cohesive connection, for example in the form of a Welded joint is arranged over the one Fixing the connection of the shaft and the adjusting element with the second drive element takes place. The socket is used in particular as an assembly aid for the adjusting element and the shaft, the respectively with the second drive element indirectly via the Socket are rotatably connected. By means of the socket can total improved stability and increased safety against so-called abuse forces can be achieved if For example, a user the operating lever as a step abused.

The cohesive connection can be made between the socket and the shaft and alternatively or additionally between the socket and the adjusting element are produced. It can be a common Weld seam between shaft, adjusting element and bush for the production of the material connection and the rotationally fixed fixation of the shaft and the adjusting element with the Socket can be used. Equally conceivable, however, are two separate ones Welds on the one hand to connect the socket with the shaft and on the other hand to connect the socket with the Adjustment element to use. In addition, you can also one or more extending in the axial direction of the shaft Welds are provided on the socket.

A if necessary, additional welding can also be done be provided between the bushing and the second drive element, to the bush rotatably connected to the second drive element. Alternatively, the socket for connection to the second drive element positively in a recess of the second drive element inserted, in particular pressed. For the formation of the positive connection the socket with the recess of the drive element has the socket while a complementary designed to the recess end Outer contour, in particular polygonal contour, on. By the Pressing the socket into the recess, the socket is free of play in the recess and is also in the axial direction relative to fixed second drive element.

To the press-fitting will be the second end of the shaft and the adjustment inserted into a bore of the socket, and the cohesive connection is used for rotationally fixed fixing of the socket with the shaft and the adjusting element produced. During assembly, the procedure is such that first the bush is pressed into the recess, then the shaft and the adjustment in their Target rotational position brought and finally with the socket rotatably connected.

at a cohesive formed as a welded joint Connection is a weld preferably transverse to the axis of rotation the shaft is arranged on the socket. The weld extends thus circumferentially about the sleeve, wherein the weld for example, circumferentially on a lateral surface a cylindrical portion of the socket can be arranged.

By the provision of the circumferential, transverse to the axis of rotation of the shaft Directed weld can be the production of cohesive Connection by a welding tool, for example a Laser welding machine, to be simplified. In particular, can on welding bags for the production of welded joints be omitted, which simplifies the production of the socket and a weakening of the bushing through one for forming the welding pockets Conditional material dilution of the socket can be avoided can. In addition, the transverse weld in any Angular position are arranged circumferentially on the socket, so that a precise alignment of the socket to the welding tool is not required.

A transverse to the axis of rotation directed weld for production In addition, the cohesive connection can be arranged so that they are suitable for a welding tool, In particular, a laser welding device easily accessible is, wherein the welding tool for making the weld Transverse to the axis of rotation of the shaft only linearly can be, but not in the axial direction must be moved.

Prefers is the weld in the circumferential direction on a lateral surface arranged a cylindrical portion of the socket and describes it a circumferential angle between 100 ° and 200 °, in particular 130 ° to 170 °. The weld surrounds the Bush therefore not fully, but sweeps only a peripheral portion of the socket.

The Welded connection is preferably exclusively on the accessible side of the door and over the socket on the outside.

Instead of a transversely directed weld may alternatively Of course, one or more welds be provided in the axial direction of the sleeve, wherein for defining the welding positions are provided welding pockets can.

Conceivable is also an attachment of one or more obliquely directed Welds or one in the manner of a zigzag their direction changing weld at the socket.

11 a perspective view of an embodiment of a socket at one end of a shaft and

12A , B representations of the socket according to 11 diagonally from above.

In the figures are like-acting parts with the same reference numerals designated.

The detent fittings shown in the figures 2 each have a first fitting part 4A and a second fitting part 4B on. These are each approximately disc-shaped. Between them, a gap is formed, in which a fitting mechanism is arranged. This includes in particular as a cam 6A , B trained drive element. The reference number 6A in this case denotes the tunnel-side cam disc (first drive element) and the reference numeral 6B the door-side cam (second drive element). The cams 6A , B are identical in the embodiment.

About the cams 6A , B and their eccentrically arranged cams, in the exemplary embodiment, three cams, one on one of the two fitting parts 4A , B radially displaceably mounted locking element actuated, so pushed in the radial direction to the outside or withdrawn. About the locking elements is a lock between the two fittings 4A , B such that they can not be twisted against each other. For example, on the in the 1 to be recognized first fitting part 4A formed on a peripheral edge an internal toothing, in which engage the locking elements with a corresponding external toothing in the closed position. The locking elements are in this case formed in the manner of plate-shaped elements, at the end face of the toothing is formed.

The cams 6A , B are rotated by means of an adjustment mechanism. This adjusting mechanism comprises a shaft designed as a hollow shaft 8th , as an adapter bolt 10 trained adjustment and in the described embodiments a socket 12 , In the final assembly position, the three components are shaft 8th , Adapter bolts 10 as well as socket 12 to each other and with the door-side cam 6B rotatably connected.

The adapter bolt 10 serves for the attachment of an actuating lever (not shown) via which a manual actuation of the fitting arrangement takes place. Pressing this lever will turn the adapter bolt 10 , with him the wave 8th and thus the two cams 6A , B twisted, so that the two locking fittings are synchronously transferred from its closed position to a release position, so that a tilt adjustment of the seat back is possible.

The Indian 1 illustrated door-side detent fitting 2 is attached to the door side of a seat, in particular motor vehicle seat, in a manner not shown here. On the opposite side, the tunnel side, another catch fitting (not shown) is attached. The two fittings 2 are over the wave 8th interconnected and form a common fitting arrangement for the motor vehicle seat. The tunnel-side fitting here has the same components and the same structure as the door-side locking fitting 2 , except that the socket 12 and the adapter bolt 10 omitted.

This identical part principle of the two locking fittings 2 is essential and allows the use of identical components, regardless of the installation position of each detent fitting 2 (Driver's seat front-passenger seat, tunnel side-door side). At the same time is through the adapter bolt 10 a customer- or model-specific adaptation to a desired operating lever possible without the common-part principle must be left.

During assembly, the procedure is such that the seat with the two fittings 2A . 26 is pre-assembled. Only then is the wave 8th through the two fittings 2A . 2 B passed. In this case, it is preferably from the tunnel side through the tunnel-side fitting 2A pushed through and in the opposite door-side fitting 2 B inserted. Of particular importance is that on the tunnel side the wave 8th rotatably with the tunnel-side drive element 6A is connected, at the same time on the door side, however, initially no specific rotational orientation of the shaft 8th with respect to the door-side drive element 6B is fixed. This ensures that when mounting one of the drive elements 6A . 6B is not rotated from its defined position, in particular from the defined closed position. This would result in an asynchronous adjustment of the two fittings 2A . 2 B which, for reasons of comfort and safety, must be avoided. Due to the initially free rotation of the shaft 8th with respect to the door-side cams 66 is therefore readily a different rotational orientation of the two fittings 2A . 2 B , compensated for example due to mounting tolerances.

During assembly, in all embodiments on the tunnel side via a positive connection between the tunnel-side end of the shaft 8th and the tunnel-side cam 6A First, a rotational position between the shaft 8th and the tunnel-side cam 6A established. This situation is in the 3A shown. In contrast, the rotational position of the shaft 8th with respect to the door-side cam 6B initially open. For the positive connection of the tunnel-side end of the shaft 8th this has a special outer contour 14 on. With its tunnel-side end is the wave 8th in a recess formed as a passage opening 16 the cam disk 6A plugged in. The recess 16 has one to the outer contour 14 complementary inner contour on. The outer contour 14 so like the inner contour of the recess 16 are generally designed to form a circumferentially effective positive engagement by insertion. With its tunnel-side end lets the wave 8th with a slight play in the recess 16 introduce.

In the embodiment of 2 to 4 has the recess 16 an approximately circular basic geometry with radially outwardly directed pockets. In the embodiment, three such offset by an equal angular amount pockets are provided. The recess 16 is therefore generally designed in the manner of a known example in screws polygonal receptacle for torque transmission.

The wave 8th is designed as a cylindrical hollow shaft, such as steel shaft, and expanded at its tunnel-side end by a forming process to the outer contour 14 to create ( 3 ). Alternatively, the shaft is formed as a continuous casting profile. In this case, the wave is 8th brought at its door-side end by a forming operation in a substantially cylindrical shape.

In the embodiment of 1 is the door-side end of the shaft 8th conically tapered and into an inner bore 122 the socket 12 plugged in. From the other side is the adapter bolt 10 with an end-side pin 18 also in the hole 122 the socket 12 plugged in. The pin 18 and the tapered door-side end of the shaft 8th are aligned approximately with each other and are largely on the inner wall of the socket 12 at. In the embodiment of 1 is the socket 12 as a Einpressbuchse with radially outwardly projecting protrusions 120 educated. How out 2 shows, the projections form 120 one to the recess 16 the cam disk 6B adapted outer contour over which the socket 12 in the recess 16 rotatably rests. At its front end, the socket tapers 12 something and thus forms an import slope 121 to allow the press-fitting. Due to the press-in is already an axial securing the socket 12 in relation to the door-side cam 6B achieved.

How farther 2 indicates the bushing 12 at her from the cam disk 6B spaced, by a cylindrical section 123 trained end around its circumference several distributed as sweat bags 20 formed recesses, which by a respective material dilution of the cylinder wall of the cylindrical portion 123 the socket 12 are formed.

The assembly process is based on the 5A to 5B clearly: First, the socket 12 into the recess 16 the door-side cam 6B pressed. The wave 8th is inserted from the tunnel side, so with its cylindrical end ahead, first through the tunnel-side cam 6A guided. On the tunnel side becomes the tunnel-side end of the shaft 8th with its outer contour form-fitting in the tunnel-side cam disc 6A plugged in ( 5B ). In the 5B is of the tunnel-side detent fitting only the tunnel-side cam 6A shown. It goes without saying that the tunnel-side locking fitting is already mounted and only the shaft 8th through the two locking fittings 2 with the cams 6A , B is guided. Due to their on the door side cylindrical configuration of the shaft 8th is it relative to the socket 12 freely rotatable. This will cause a twisting of the drive element 6B avoided from its defined closed position during assembly. In the subsequent, in 5C The assembly step shown is the adapter bolt 10 in the socket 12 plugged in.

In this Zwischenmontageposition is the rotational position of the adapter pin 10 as well as the wave 8th in relation to the socket 12 and thus the cam disc 6B in principle free. This is on the one hand for the synchronization of the two fittings on the shaft 8th and for the desired rotational position of the later to be mounted operating lever via the adapter pin 10 really important. Are oriented in this intermediate mounting position, the individual components in the desired rotational position, they are rotatably connected to each other. In the embodiment of 5C this is done via a welded connection shown schematically. The corresponding weld 22 is in 5C exemplified. It runs in the longitudinal direction of the shaft 8th in the area of welding bags 20 , How out 5C can be seen, sweeps over the weld 22 the pin 18 and an end piece of the shaft 8th so that with only one weld at the same time both the shaft 8th as well as the adapter bolt 10 with the socket 12 are materially connected. In addition, further welds or welds may be provided, for example, the adapter bolt 10 over a circumferential weld complementary to the socket 12 welded. Of particular advantage here is generally that the welds 22 on the door side and due to the socket 12 slightly spaced from the fitting part 4B and thus be made accessible.

A modified embodiment of the socket 12 with one arranged on it, in the circumferential direction around the socket 12 aligned weld 22 is in 11 and 12A . 12B shown. The socket 12 has, as described above, at its one end by a projection 120 formed outer contour, which in the recess 16 the cam plate forming the second drive element 6B the door-side fitting 2 is pressed. Front side is at the Rifle 12 an import slope 121 formed, which is the insertion of the socket 12 with their projections 120 into the recess 16 the cam disk 6B to simplify. At its other end, the socket 12 a cylindrical section 123 on, on its lateral surface circumferentially transversely to the axis of rotation D of the shaft 8th the weld 22 is arranged.

The socket 12 has a central inner bore 122 on, in the for assembly of the one, in 11 rear side of the shaft 8th with its tapered end and from the other side of the adapter bolts 10 (please refer 1 ) is inserted. About the circumferential weld 22 becomes a cohesive connection for rotationally fixed fixation of the shaft 8th and the adapter bolt 10 at the hole 122 the socket 12 produced. The weld 22 can be so for example in the area of the socket 12 in which the wave 8th and the adapter bolt 10 in the hole 122 abut each other, be attached that over the one weld 22 both the wave 8th as well as the adapter bolt 10 cohesively with the socket 12 get connected. However, it is also conceivable, two separate welds 22 provide, on the one hand a cohesive connection between the socket 12 and the wave 8th and on the other hand, a material connection between the socket 12 and the adapter bolt 10 getting produced.

12A and 12B show further views of the embodiment of the socket 12 according to 11 , How out 12B can be seen, describes the weld 22 a circumferential angle α on the lateral surface of the cylindrical portion 23 the socket 12 , which may be between 100 ° and 200 °, preferably between 130 ° and 170 °. The length of the weld 22 is based on the strength requirements of the connection between shaft 8th , Adapter bolts 10 and socket 12 to choose.

Likewise in 12B the direction of movement B of a trained by a laser L welding tool is shown, due to the arrangement of the weld 22 transverse to the axis of rotation D of the shaft 8th is also directed transversely to the axis of rotation D.

By the arrangement of the weld 22 transverse to the axis of rotation D various advantages can be achieved.

On the one hand, by providing the weld 22 transverse to the axis of rotation D, the geometry of the socket 12 be simplified because sweat bags (see 2 ) can be omitted for attaching the weld. This simplifies the manufacture of the socket 12 , and also the manufacturing cost of the socket 12 reduce themselves.

The fact that no more sweat pockets must be provided, also the strength of the socket 12 and thus the connection of the adapter bolt 10 and the wave 8th with the door-side cam 6B improved. The elimination of the sweat pockets is a weakening of the cross section of the socket 12 avoided due to a portionwise thinning of material.

Second, by attaching the weld 22 be facilitated in the transverse direction of the assembly process, as the weld 22 circumferentially in any angular positions on the socket 12 can be attached. This is a precise alignment of the socket 12 no longer necessary for the welding tool in the circumferential direction.

The third is by arranging the weld 22 In the transverse direction, the accessibility of a welding tool significantly improved because the weld 22 at a distance from the catch fitting 2 , in particular the second fitting part 4b can be attached and a method of the welding tool in the axial direction is not required. The production of the weld 22 can be done by a linear method of the welding tool in the transverse direction.

From the 6 is a second embodiment for the door-side detent fitting 2 shown. In this embodiment, the adapter pin 10 a long spigot 24 on that through the entire socket 12 stuck through it. End faces the cylindrical end of the long pin 24 a circumferential knurling 26 on, which is formed by individual, distributed around the circumference arranged and preferably tapered in the manner of teeth webs. The front end has a conical inlet slope.

The connection between the adapter bolt 10 and the socket 12 takes place as embodiment of the 5C over a welded joint.

When mounting the in 6 illustrated door-side detent fitting 2 in turn, the socket is first 12 into the cam disc 6B in particular pressed. Subsequently, the adapter bolt 10 through the socket 12 put through and brought into the desired rotational position. Finally the wave 8th from the tunnel side on the long pin 24 pressed. Because of this knurling 26 In this case, an effective form-fitting connection in the circumferential direction is likewise formed. When pressing in, therefore, form the individual longitudinal webs of the knurling 26 in the inner shell of the hollow shaft 8th one.

A third embodiment of the door-side detent fitting 2 in two different ages native is now based on the 7A to C, 8A . 8B and 9 explained in more detail.

In contrast to the previous embodiments, the socket 12 not in the recess 16 Pressed, but only inserted rotatably. In the axial direction is no firm connection between the socket 12 and the cam disk 6B designed so that occurring axial forces are not on the cam 6B be transmitted. For this embodiment, both the socket 12 as well as the wave 8th designed as a circumferential gutter stop 28 on. The wave 8th is again in the socket 12 plugged in. With the two stops 28 These two components are each at the two fittings 4A B, so that their axial position is fixed. Subsequently, the adapter bolt 10 both in the socket 12 as well as in the wave 8th plugged in. He has for this purpose two mutually in the axial direction subsequent pin 30A , B with different diameter. The front pin 30A with the smaller diameter is in the shaft 8th plugged in while the rear pin 308 with the larger diameter in the socket 12 is plugged in. The adapter bolt 10 rests against the socket 12 with a bunch 32 from. In the embodiment according to the 7 and 8th the fixation of the rotational positions by means of a substance-liquid connection by welding takes place. In the 8A , B are here different positions for possible welds 22 shown. These can extend in the axial direction in the welding pockets 20 , annular or discontinuous circumferential, or be designed as individual welds. How out 7C can be seen, by a single example, annular circumferential weld 22 in the area of the wave 8th and the front pin 30A a rotationally fixed connection between the three components are produced.

Alternatively to the welded joint is according to 9 an attachment provided by means of a simple press-in connection. For this purpose, the two pins 30A , B each have a circumferential knurling 26 on, with which they each have a form-fitting press-in connection with the inner wall of the socket 12 or the inner wall of the shaft 8th form.

In the 10A Finally, B is an alternative embodiment for the design of the outer contour 14 and the corresponding inner contour of the recess 16 shown. In this embodiment, a substantially hexagonal polygonal structure in contrast to the triangular polygonal structure according to the 3 and 4 intended.

As in particular from the 10B becomes clear, is the wave 8th expanded at its tunnel-side end by a forming process, thus has a larger diameter than in its remaining area. This allows the shaft 8th each inserted during assembly of the tunnel side and pushed through to the opposite, door-side latching fitting, where the shaft 8th with its cylindrical end either in the socket 12 inserted and / or on the pin 18 . 24 . 30A pushed or pressed.

• – Aufgrund des Gleichteileprinzips sind alle Rastbeschläge 2 identisch ausgebildet, lediglich in einem letzten Montageschritt wird die Position des jeweiligen Beschlags durch die Anordnung der Buchse 12 und insbesondere des Adapterbolzens 10 festgelegt;
• – durch die freie Drehbarkeit der einzelnen Bauteile in der Zwischenmontageposition auf der Türseite zueinander ist eine synchrone Einstellung der Drehposition der beiden Nockenscheiben 6A, B sichergestellt;
• – der Adapterbolzen 10 lässt sich problemlos in eine gewünschte Drehstellung aufgrund der freien Beweglichkeit in der Zwischenmontagestellung bringen.

By the fitting arrangement described here with the special connection between the shaft 8th and the respective catch fitting 2 the following significant advantages are achieved:

• - Due to the common-part principle, all locking fittings 2 identically formed, only in a final assembly step, the position of the respective fitting by the arrangement of the socket 12 and in particular the adapter bolt 10 set;
• - Due to the free rotation of the individual components in the intermediate mounting position on the door side to each other is a synchronous adjustment of the rotational position of the two cam discs 6A , B ensured;
• - the adapter bolt 10 can be easily brought into a desired rotational position due to the freedom of movement in the intermediate assembly position.
