  • From the DE 44 36 108 A1 a fitting for a vehicle seat is known, comprising: a movable plate means which is fixed to a backrest of the seat; a base plate device fixed to a seat cushion of the seat; an axle device in which one end is rotatably connected to one of the movable plate means and base plate means and the other end is secured to another of the movable plate means and base plate means; the movable plate means being rotatable about the axle means with respect to the base plate means; a first lock gear device which is arranged in one of the movable plate means and base plate means at a point to which the one end of the axle means is connected; second detent gear means movable in a direction along a longitudinal axis of the axle means to be engaged with or disengaged from the first detent gear means; biasing means for biasing the second parking gear means toward the first parking gear means so as to normally maintain engagement between these two parking gear means; a lever device; an engagement means provided between the second lock gear means and the lever means, whereby operation of the lever means causes the second lock gear means to be moved along the longitudinal axis of the axle means in a direction away from the first lock gear means against a biasing force of the bias means, whereby the first lock gear means is brought out of engagement with the second Feststellzahnradeinrichtung. All the elements described above are mounted in common between the movable plate means and the base plate means substantially along the longitudinal axis of the axle means. Here, it is provided that the point to which the one end of the axle device is rotatably connected is a hole formed in a lower end portion of one of the movable plate device and base plate device and in which the one end of the axle device is rotatably secured said first parking gear means is formed adjacent said bore so as to substantially adopt an annular detent gear portion, and said second detent gear means is also formed in the same annular shape to permit engagement thereof with said annular first detent gear portion thus formed. The annular first detent gear portion is chamfered to assume a substantially frusto-conical recessed gear configuration about the bore, and the second detent gear annular means is also chamfered to assume a substantially frusto-conical shaped gear configuration for frusto-conical engagement therewith allow first Feststellzahnradbereich.
  • Another fitting for tilt adjustment of the backrest of a vehicle seat is from the WO 97/20706 A1 known. The corresponding vehicle seat has an elongate shaft of circular cross-section disposed along a pivot axis, the ends extending through aligned openings of fittings associated with the seatback. On the shaft a locking member is rotatably and longitudinally displaceable. An adjusting element in the form of a radially projecting on both sides of the shaft projecting pin is engaged in corresponding, obliquely extending oblong holes in the locking part. The locking member further comprises two separately formed teeth. A first crown gear is provided for locking the locking part with the first fitting part, wherein the first fitting part is formed with a corresponding Kronradverzahnung. Furthermore, the locking part has a second, conical conical toothing, which cooperates in the locked state with a corresponding conical toothing of the second fitting part. The first and second fitting part are mounted directly to each other. If the shaft is rotated by means of the handwheel, the bevel gears preferably disengage during disengagement. Conversely, when engaged, the crown gears preferably engage, which teeth may have sloping sidewalls to facilitate engagement of the bevel gears. Here, the teeth formed on the locking part engage in different components, wherein these components are movable relative to each other.
  • The invention is based on the object to provide an improved fitting. In particular, the lock should be secured and the security of infallibility improved.
  • This object is achieved by a fitting with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.
  • By providing a bearing element with a ramp region having at least one ramp and at least one part plane, wherein the Partial level projecting further and is arranged in a plane which extends perpendicular to the axis of the bearing element, and a locking member having a first ramp portion with at least one ramp and at least one part plane, wherein the ramp portion cooperating with the ramp portion of the bearing element and the two ramp portions an axial Allow displaceability of the locking member, can be a simple displaceability of the locking member realize, in particular, the surface pressure can be kept low by suitable ramp design. Furthermore, by providing a locking part, which is not formed by a spring element, realize a positive locking in the axial direction of the locked position. To release the lock, the blocking element passes into a receptacle formed by the corresponding ramp region, so that it no longer has any influence on the longitudinal position of the locking element with respect to the first fitting part and in this position the interlocking formed between the first fitting part and the locking part completely solved.
  • The locking element has in a preferred embodiment, a ring portion with inwardly extending arms, said arms with the ramps and sub-levels and provided in the ramp area attacks, which are provided between a ramp and a part plane and extending in a plane radially and parallel to the axis , collaborate. The blocking element preferably has a constant thickness.
  • Particularly preferably, when the arms of the blocking element bear against the stops of the locking part, the arms extend as far as the height of the plane formed by the part planes, whereby the blocking element is arranged within the ramp area viewed from the radial direction from the side. On the other hand, when the arms rest on the part planes, the blocking element is arranged offset in an offset manner to the ramp region of the locking part. In this case, the displacement is preferably effected exclusively by a movement of the locking element in the axial direction, while the locking element is stationary in the axial direction.
  • Preferably, at least two, in particular three to six ramps, very particularly preferably in each case exactly three ramps, and the same number of sub-levels are provided at each of the ramp areas. This allows a particularly good support over the circumference.
  • The blocking element preferably has an arm extended as a guide arm, which is guided in a groove of the bearing element. Therefore, a rotation of the bearing element takes with the blocking element, wherein it, preferably guided elsewhere on the ramps or sub-levels, its position in the longitudinal direction of the axis can not or at least only slightly change. The blocking element is preferably located on the inner end face of the second fitting part, wherein a relative rotation is possible, but is stationary in the axial direction. However, it is preferably the relative sliding of the arms along the ramps greater than the displacement of the locking member in the longitudinal direction of the axis.
  • In addition to the blocking element, a spring element, in particular in the form of a plate spring, be provided between the locking part and one of the fitting parts, wherein the spring element biases the locking part in the direction of the locked position. In this case, the spring element is particularly preferably arranged at the same height as the blocking element, with the longitudinal extension of the spring element preferably varying by the displacement path of the blocking element in the longitudinal direction of the axis.
  • Particularly preferably, the locking part has an external toothing and a crown gear, the first fitting part a corresponding internal toothing and crown gear teeth and the second fitting part an internal toothing, wherein the transition from the unlocked position to the locked position, the crown gear toothing of the locking part interacts centering with the internal toothing of the first fitting part before the external toothing engages in the internal toothing of the first fitting part, and in the fully locked position, the two internal toothings of the fitting parts interact with the external toothing of the locking part and at the same time engage the crown wheel toothings. Such a configuration of the teeth is possible in principle in any other fitting with external / internal teeth and crown gear, but especially without ramp areas and blocking element.
  • Preferably, the bearing element is integrally formed. Particularly preferably, it has a rivet head, which holds the other parts of the fitting.
  • The fitting according to the invention is preferably used in vehicle seats for adjusting the backrest inclination, but can also be used in other places.

  • 10 a front view, and
  • 11 a schematic representation of a vehicle seat.
  • A vehicle seat 1 for a motor vehicle has a seat part 3 and a relative to the seat part 3 in its inclination adjustable backrest 4 on. For tilt adjustment of the backrest 4 is done manually, for example by means of a handle 5 , A present not point-symmetrically formed transmission rod rotated, which horizontally in the transition region between the seat part 3 and backrest 4 is arranged. On both sides of the vehicle seat 1 engages the transmission rod in a fitting 10 one. The transmission rod defines the direction information used for a cylindrical coordinate system.
  • The fitting 10 is designed as a detent fitting, in which a first fitting part 11 and a second fitting part 12 with each other by means of a locking part 13 Lockable and after unlocking relative to each other about a (aligned with the transmission rod) axis A are rotatable. The first fitting part 11 is present with the structure of the backrest 4 connected directly (or via an adapter). The second fitting part 12 is present with the structure of the seat part 3 connected directly (or via an adapter). The parts 11 . 12 and 13 sit on a bearing element 14 , which in turn sits torsionally rigid on the transmission rod by the bearing element 14 has an inner profile corresponding to the transmission rod. Furthermore, they are part of the fitting 10 a plate spring 15 , a blocking element 16 , a sliding element 17 and a washer 18 , wherein the sliding element 17 and the washer 18 possibly also be omitted.
  • The bearing element 14 is presently designed as a forming part, wherein it after the assembly of the fitting 10 with a rivet head 14a is provided. In principle, however, a multi-part design, for example as a kind of bolt with a mother sitting on a thread, would be possible. In the exploded view of 1 and the individual representation of the bearing element 14 is the rivet head 14a not yet formed while shown in the assembly drawings.
  • The bearing element 14 has a head 14b whose underside has a contact surface 14c for the first fitting part 11 , and a subsequent cylinder surface 14d on, on which the first fitting part 11 sitting. A first gradation 14e has several, in this case three ramps 14f on. The ramps 14f extend obliquely and curved at the beginning and end tangent to the plane perpendicular to the axis A, springing back towards the head 14a , starting from a plane which extends radially to the axis A and through three sub-levels 14g is formed. An extending in the radial direction to the axis A stop 14h lies between each one ramp 14f and a part level 14g , The distribution over the circumference considered is present such that the ramps 14f Seen in the circumferential direction a little less than the part levels 14g extend (cf. 8th . 9 ).
  • On the gradation 14e There follows a further substantially cylindrical region, in which a parallel to the axis A extending groove 14i is trained. On this area is called leadership 14j Referenced. The management area 14j ends with another, second gradation 14k , which serves as a contact surface for the washer 18 which serves on a cylindrical end portion 141 sitting. The over the washer 18 projecting portion of the cylindrical end portion 141 will after assembling the fitting 10 , as already mentioned, to said rivet head 14a reshaped, leaving the washer 18 close to the second gradation 14j is applied.
  • The first fitting part 11 which is on the bearing element 14 sits and with its outward facing face 11a at the contact surface 14c Of the head 14b of the bearing element 14 rotatably rests and with a cylindrical opening 11b on the cylindrical surface 14d sits, points in the axial direction in the direction of the second fitting part 12 protruding edge area 11c on, which has an inner end face 11d protrudes. In the area of the outer circumference of the inner end face 11d and on the inner circumferential surface of the edge region 11c is a straight internal toothing 11e and a straight crown gear teeth 11f formed, wherein the teeth are present designed such that they extend continuously over the inner edge.
  • The second fitting part 12 has in principle a similar shape, with an outwardly facing end face 12a at the washer 18 is present, a cylindrical opening 12b on the leadership area 14j of the bearing element 14 sits, one in the axial direction in the direction of the first fitting part 11 protruding border area 12c is provided, which has an inner end face 12d protrudes. In contrast to the first fitting part 11 is a straight internal toothing 12e only in the inner circumferential surface of the edge region 12c formed, but not in the inner face 12d , The internal toothing 12e corresponds exactly to the internal toothing 11e the inner circumferential surface of the first fitting part 11 ,
  • The locking part 13 has a straight outer toothing on the outer circumference 13a and at the first fitting part 11 facing end face 13b a straight crown gear teeth 13c on, which are suitable, with the straight internal teeth 11e or the straight crown gear teeth 11f to get in touch. Here is the external toothing 13a formed such that it depends on the position of the locking part 13 in relation to the two fittings 11 . 12 either only in engagement with the corresponding internal toothing 12e of the second fitting part 12 or in engagement with the internal gears 11e . 12e both fitting parts 11 . 12 is, in the correctly locked state, the crown gear 13c in engagement with the corresponding crown gear teeth 11f stands.
  • The locking part 13 also has a cylindrical opening 13d on, through which the bearing element 14 with his leadership 14j protrudes. In the border area around this opening 13d a structure is formed on both sides, which the ramp-part-plane structure of the bearing element 14 similar. So are on the first fitting part 11 facing side ramps 13f and part levels 13g with stops 13h and on the second fitting part 12 facing side ramps 13i and part levels 13j with stops 13k formed, whose dimensions are those of the bearing element 14 but the tangential areas of the ramps are 13f and 13i shorter than the ramps 14f trained (cf. 9 ). The adjacent end face areas are flat and perpendicular to the axis A.
  • Outside the external toothing 13a of the locking part 13 is the sliding element 17 between the mutually facing sides of the edge regions 11c . 12c the first and second fitting part 11 . 12 arranged. The sliding element 17 has an inner diameter slightly larger than the outer diameter of the outer teeth 13a of the locking part 13 is, and an outer diameter that is about the outer diameter of the two fitting parts 11 . 12 equivalent. It serves to ensure that the friction in case of a relative movement between the two fitting parts 11 . 12 is kept low, in particular, that no "seizure" is possible. With the sliding element 17 it may be, for example, a plastic part.
  • On the side of the second fitting part 12 adjacent to the locking part 13 are the plate spring 15 and the blocking element 16 arranged. The plate spring 15 has an outer diameter which is dimensioned such that the plate spring 15 in the maximum tensioned state with its outer edge region 15a on the second fitting part 12 on its inner face 12d near the inner end of the edge area 12c is applied. It also has an opening with an inner diameter, with the inner edge region 15b at the second fitting part 12 facing side of the locking part 13 is applied. The plate spring 15 clamps the locking part 13 in the direction of the first fitting part 11 before, where they are on the second fitting part 12 supported.
  • Inside the plate spring 15 is the blocking element 16 arranged. The blocking element 16 is ring-shaped with a ring area 16a and three inwardly extending arms 16b educated. The thickness of the barrier element 16 preferably corresponds to the height of the stops 13k of the locking part 13 , The inner diameter of the ring area 16a is slightly larger than the outer diameter of the peripheral area around the opening 13d of the locking part 13 in which the ramp part-plane structure is provided. The arms distributed equidistantly around the circumference 16b extend into the edge area, with two of the arms at the level of the opening 13d of the locking part 13 and the third arm, hereinafter also as a guide arm 16b ' denotes, extending slightly beyond it, being in the groove 14i of the bearing element 14 is included. The poor 16b of the blocking element 16 lie - depending on the position - at the attacks 13k and the lowest area of the ramps 13f the ramps 13f or the part levels 13g of the locking part 13 at. The other side of the barrier element 16 lies on the first fitting part.
  • The following is the function of the fitting 10 , in particular the effect of the blocking element 16 and the gearing, discussed in more detail.
  • In the unlocked state, for example, in 2 is shown, are the first fitting part 11 and the locking part 13 out of engagement, ie the locking part 13 is with its external teeth 13a completely in the internal toothing 12e of the second fitting part 12 added. In this position are the part levels 14g and 13g the ramp areas of the bearing element 14 and the locking part 13 in flat contact with each other, so that the locking part 13 in the farthest from the first fitting part 11 distant position. The plate spring 15 This is maximum compressed and pushes the blocking element 13 in the direction of the first fitting part 11 , wherein a shift by the surface conditioning of the part planes 14g and 13g is prevented. In this position is simultaneously the blocking element 16 with his arms 16b at the bottom of the ramps 13i in attachment to the attacks 13k (please refer 6 ). Thus, the blocking element 16 is in principle within the height of the direction in the direction of the second fitting part 12 extending edge region of the barrier element 13 so that this is in its second fitting part 12 next position.
  • By turning the transmission rod, the bearing element 14 turned, this takes on its rotation in the groove 14i the guide arm 16b ' of the blocking element 16 With. The rotation causes a relative rotation of the locking element 16 with respect to the second fitting part 12 and the locking part 13 , which are rotatably connected to each other via the toothing, wherein the blocking element 16 does not change its axial position (cf. 4 and 5 ). The at the attacks 13k adjacent arms 16b of the blocking element 16 otherwise prevent rotation of the bearing element 14 - and thus the transmission rod - in the wrong direction.
  • Due to the relative movement, the arms move 16b of the blocking element 16 over the ramps 13i on the part levels. As a result, the bearing element 14 rotates, the ramp portion thereof rotates with respect to the corresponding ramp portion of the locking member 13 so that is no longer the end of the ramp 13f near the stop 13h of the locking part 13 at the part levels 14g rests, but this end of the ramp 13f along the ramp 14f slides and in the fully locked state of the stop 13h at the stop 14k is present (see 9 ). This happens with the participation of the diaphragm spring 15 which the locking part 13 from the blocking element 16 , which is in contact with the second fitting part 12 is (and this remains) in the direction of the first fitting part 11 pushes.
  • Because the blocking element 16 in both end positions on flat areas (sub-levels 14g /Attack 14h ) of the bearing element 14 not in the areas of the ramps 14f , It ensures a positive power transmission in the axial direction, so that no axial displaceability of the locking element 13 is possible, especially even if the plate spring 15 should fail.
  • By turning the transmission rod and the associated relative movement reaches the beginning of the sliding movement of the locking member 13 the transition region between the crown gear teeth 13c and the external teeth 13a of the locking part 13 in contact with the internal toothing 11e of the first fitting part 11 , Due to the wedge-like design of the teeth, the threading of the teeth is greatly facilitated. A slight play facilitates the correct alignment of the internal teeth during insertion 11e of the first fitting part 11 in relation to the internal teeth 12e of the second fitting part 12 , Aligned ensures that at maximum displacement of the locking part 13 the crown gear teeth 11f and 13c are aligned correctly, so that in an intervention of the same no further alignment correction is required.
  • By providing a crown gear and external teeth on the locking part 13 , wherein the teeth on the locking part 13 pass directly into each other, the number of possible "dead positions", ie positions in which tooth meets tooth and thereby intervention in the case of pure external teeth is prevented, minimized by the fact that the above crown gear teeth on the locking part 13 a centering of the locking part 13 when engaging in the internal toothing of the first fitting part 11 allows. The meshing inner and outer gears simultaneously allow a large power transmission, so that the combination of gears is particularly advantageous.
  • Although in the present case an attachment of the first fitting part 11 on the structure of the backrest 4 and the second fitting part 12 on the structure of the seat part 3 is described, the attachment of the fitting parts 11 . 12 Of course, be reversed, ie the first fitting part may be attached to the structure of the seat part and the second fitting part on the structure of the backrest.
  • It should also be noted that instead of a plate spring, any other element can be used. In principle, even one Elimination of the spring possible, but in this case are preferably provided elsewhere spring elements or other safety measures to prevent accidental unlocking due to a displacement of the locking member 13 relative to the first fitting part 11 in case of failure of the blocking element 16 To prevent and further ensure that when released handle 5 an automatic locking takes place. In principle, a force acting in the locking direction force is also conceivable by the action of gravity on a correspondingly lever-like handle.
