Background technology
Second fitting part that this Detent fitting has first fitting part and rotatably is provided with respect to first fitting part round rotation axis.At least one lockable mechanism is arranged on first fitting part movably; Said lockable mechanism can mesh with the tooth portion of second fitting part; To be used for first fitting part and the locking of second fitting part; And said lockable mechanism can with the tooth portion jump out of mesh of second fitting part, unlock being used to.For the control lock locking mechanism, for example can be provided with can be with respect to the control panel of first and second fitting parts rotation for this reason, and said control panel cooperates with at least one lockable mechanism, to be used to form or to unlock.
Detent fitting for example can be used to connect backrest and seat member on automotive seat; The Detent fitting that wherein structure is identical can be arranged on the both sides of automotive seat; And for example, first fitting part is connected with seat member and second fitting part is connected with backrest.Under lock-out state, Detent fitting with backrest retainer in position with respect to seat member.In order to rotate backrest, can unlock, and therefore adjust the position of seat member with respect to backrest with respect to seat member.
When backrest rotates; For example in order easily to enter on the bench seat in automotive seat back (so-called " getting into function easily " of two-door automobile) or when rotating forward for storeroom (in so-called " the fold-flat function " of four automobiles) is provided; What can expect is in predetermined angular range, to prevent the locking of Detent fitting.For this purpose; At least one free rotation section section is set on second fitting part; Its formation and being set to; When second fitting part rotates in the angular range of being scheduled to of the free slewing area of qualification with respect to first fitting part, cooperate with lockable mechanism, and prevent the tooth portion engagement of the lockable mechanism and second fitting part.
Known Detent fitting for example has two lockable mechanisms that are arranged on movably on first fitting part from EP 1 066 170 B2; Said lockable mechanism radially moves through control panel; And, can mesh thus, with the tooth portion on second fitting part in order to lock Detent fitting; Perhaps in order to unlock, can with tooth portion jump out of mesh.Embedding on the ring with the second fitting part bonded assembly; Two free rotation section sections constitute radially inwardly out-of-position portion section; Said section is associated with lockable mechanism respectively and prevents that in predetermined angular range lockable mechanism from outwards moving, so that in this angular range, get rid of the locking of Detent fitting.Limit free slewing area thus, wherein first and second fitting parts of Detent fitting can freely rotate each other, make the backrest that for example can adjust automotive seat with respect to seat member, said backrest pass through Detent fitting and are connected with seat member.
Other forms of implementation of known Detent fitting from DE 10 2,006 015 560 B3, DE 10 2,006 000 523 A1 and DE 102 17 873 B4.
When providing free rotation section section, ring has following problem use embedding; Promptly embed ring and be installed on second fitting part that is associated as additional member and must confirm, which type of additional installation steps be essential and possibly make install complicated.
Summary of the invention
The objective of the invention is, a kind of Detent fitting that is used to lock two automotive partss is provided, said Detent fitting realizes embedding the simple installation of ring, and said embedding ring is used for when remaining on the fitting part that is associated safely, limiting free slewing area.
The Detent fitting of the characteristic of this purpose through having claim 1 is realized.
Correspondingly, embedding ring is inserted in the accommodation section on second fitting part and flexibly tensioning in the accommodation section.
The present invention is based on following thought, be provided with the embedding ring that is used to limit free slewing area, said embedding ring is placed on second fitting part, and through by the flexibly tensioning and being connected with this second fitting part of second fitting part antitorquely.At this; Tensioning for example can be carried out as follows; The shape of exterior circumference that promptly embeds ring shape of holding profile with the accommodation section that for example constitutes recess of second fitting part under relaxed state is different; Make to embed ring and be matched with the moulding of accommodation section, being used for being inserted into the accommodation section, and correspondingly must tensioning.At this, the distortion that embeds ring is preferably elastomeric, is not plasticity promptly, makes enough tensile forces between embedding ring and accommodation section, to occur and after from the accommodation section, shifting out, embed ring getting back to its shape initial, that relax once more.
Owing to embed tensioning when encircling in inserting the accommodation section, therefore simplified embedding the installation of ring on the accommodation section.Especially need not be used for additional measure, and the top is installed also overhead carry out, after inserting, can not from second fitting part, come off and embed ring at the fixedly embedded ring of second fitting part (axially).Therefore, embed the installation of ring on second fitting part and reduce to insertion process itself.Other steps that need not be used for fixedly embedded ring on second fitting part.
Embed ring and for example can constitute the osed top ring, under the relaxed state before being inserted into the accommodation section, the moulding of the exterior periphery of said ring is different with the moulding of accommodation section, and under situation about inserting, the flexibly tensioning in the accommodation section of said embedding ring.In this case, the accommodation section for example constitutes the recess with circular basically side face, and non-circular through embedding the exterior periphery formation of encircling, and under lax state, the exterior periphery that embeds ring is different with the moulding of the side face of circle.Then, on the accommodation section that is placed in second fitting part, it is circular and by the second fitting part tensioning to embed the ring resilience landform.
In favourable form of implementation, the exterior periphery that embeds ring constitutes oval and in (circular) accommodation section that flexibly is inserted under the slack-free situation on second fitting part.But can also consider to embed other moulding of ring, the subtriangular or dimetric moulding that for example (has the angle of rounding), and therefore cause and embed ring and be divided into three parts or four parts widely.
In replaceable embodiment, embedding ring can also be by the band manufacturing of longitudinal extension, and said band is on the accommodation section that is placed in second fitting part and curve ring and be arranged on second fitting part.Therefore; Embed ring and be not made for the osed top ring; But be made for the band of forming by the elastomeric material of part at least; And just form annular in time in the accommodation section that is inserted on second fitting part, and at this, tensioning in the accommodation section that for example constitutes exterior side face recess, that have circle on second fitting part.
Embedding ring can process by metal and forms the blanked part of especially elastomeric spring steel composition.The embedding ring that constitutes the osed top ring or constitute band plastic deformation not in the accommodation section that is inserted on second fitting part time; But maintenance elasticity, feasible embedding encircles in tensioning on second fitting part and is held on second fitting part owing to its elastomeric (elastic force) tries hard to keep thus.
Can be instead possible be, minimizing under the situation of cutting loss, embed ring and process through (moulding) sintering by its agglomerated material.
Embed ring and can also must guarantee wherein that by the plastics manufacturing plastic parts of processing has enough intensity in principle.
What can also imagine is, embeds ring by a plurality of single part manufacturings, and said single part is welded to one another, so that therefore obtain the osed top ring or be used to provide the suitable band that embeds ring.Can instead also can imagine; The a plurality of parts that embed ring can be inserted in the corresponding recess on second fitting part and tensioning separately in these recesses; Make and use each section, the independent free rotation section section of said paragraph qualification on second fitting part.
Embedding ring for example can removably be connected with second fitting part; Wherein embed ring and on its exterior periphery, have recess; Said recess can engage with the positioning salient on second fitting part, to be used for that the embedding ring is arranged on second fitting part antitorquely.Through recess and the positioning salient that is associated on second fitting part, embed ring and along the circumferential direction be fixed on second fitting part, feasible embedding ring remains on second fitting part antitorquely and can not rotate round rotation axis.
Use the independent embedding ring of removably waiting to be fixed on second fitting part to realize to use different embeddings to encircle different free rotation section sections is provided; Make through using the embedding ring of coupling separately, can set up the Detent fitting of the use that is used to confirm.Therefore, the Detent fitting that this external structure is identical can adapt to condition of different and requirement through using independent embedding ring.Different embedding rings has different free rotation section sections, and therefore limits the different free slewing area of Detent fitting, and said free slewing area is equivalent to following angular range, and in said angular range, Detent fitting can not be locked.
But replaceable is that the embedding ring also can be connected with second fitting part after insertion regularly, for example welds, and is fixed on second fitting part so that will embed ring.
In preferred form of implementation; At least one free rotation section section constitute the guide-contour that is arranged on second fitting part with respect at least one other section inside out-of-position portion section radially; Cooperate with the convexity that is associated on lockable mechanism in this for example free rotation section section; Wherein in predetermined angular range, when first fitting part rotated with respect to second fitting part, convexity was arranged in the zone of free rotation section section; And, avoid lockable mechanism can move in the outside position, footpath and can reach the engagement with tooth portion on second fitting part because free rotation section section is radially to bias internal.
In the embodiment that embeds ring, at least one free rotation section section is bent to has the end segments that is parallel to said rotation axis (A).Free rotation section section constitutes the radially inside out-of-position portion section that embeds ring, and in axial direction crooked in the radially inner end segments of free rotation section section.Thus, increase the area of contact of free rotation section section and the convexity on lockable mechanism, perhaps free rotation section section contacts with protruding so that cause free rotation section section in axial direction towards the convexity guiding.
In principle, the Detent fitting like the invention of introduction here can have one, two, three, four or also more lockable mechanism.Yet in favourable form of implementation, Detent fitting has three lockable mechanisms, and they are associated with free rotation section section respectively.Therefore on first fitting part, be provided with three lockable mechanisms movably, and on second fitting part, constitute three free rotation section sections antitorquely.Three lockable mechanisms are in the tooth portion engagement with second fitting part under the lock-out state of Detent fitting, and can on second fitting part, radially move in order to unlock and therefore with the tooth portion jump out of mesh of second fitting part.

In order to lock; On first fitting part 2, be provided with three round squint each other 120 ° lockable mechanism 25 of S. A. A; It is radially adjusted direction V through director element 21,22 and is installed in movably on first fitting part 2, and can be through the tooth portion that constitutes the internal tooth portion on annular section 33 31 engagements of the exterior tooth portion 250 and second fitting part 3 in order to lock Detent fitting 1.
Under the state shown in Fig. 1, lockable mechanism 25 is in the position of radially outward moving, in said position, and tooth portion 31 engagements of the tooth portion 250 of lockable mechanism and second fitting part 3.Under this state, Detent fitting 1 locking can not be rotated the fitting part 2 of winning with respect to second fitting part 3.
In form of implementation according to Fig. 1; Radially guide the director element 21,22 of lockable mechanism 25 constitute projection, towards second fitting part 3 from the outstanding portion's section of disc shaped matrix 20, and be used for radial directed lockable mechanism 25 on the one hand and be used on the other hand first fitting part 2 is bearing in second fitting part 3.For this reason, the outer segments 211,221 of director element 21,22 is close to the tooth portion 31 of the internal tooth portion that constitutes of second fitting part 3 with the mode of sliding, and the fitting part 2 of winning can be rotated with respect to second fitting part 3 around rotation axis A.
The locking of Detent fitting 1 forms through lockable mechanism 25, and said lockable mechanism tooth portion 31 through the tooth portion 250 and second fitting part 3 under lock-out state meshes.In this case; Operable lock locking mechanism 25 locks Detent fitting 1 or unlocks and can carry out through the control panel 4 that is arranged between first fitting part 2 and second fitting part 3; Said control panel constitutes disc, and has and be used for shape and be contained in the center accommodation hole 42 that the transmission shaft of fitting part 2,3 is passed at recess 27,32 places with engaging.
On control panel 4, constitute squint each other 120 ° the identical chute 41 of structure around rotation axis A, the convexity 251 of lockable mechanism 25 joins to respectively in the said chute.Protruding 251 are close to the outside slide groove portion section 410 of chute 41 respectively, and when control panel 4 rotates around rotation axis A, slide along outside slide groove portion section 410.
On control panel 4 and at dorsal part, be provided with face cam 43 (see figure 2)s of the projection that constitutes with outstanding mode; Said face cam constitutes guide section 430 on its exterior periphery, said guide section contacts with lockable mechanism 25 on being installed in first fitting part 2 through the cam on the bottom that is formed in lockable mechanism 25 respectively 252.
Under lock-out state;---under this state; Lockable mechanism 25 radially outward moves and meshes through the tooth portion 31 of its tooth portion 250 and second fitting part 3---; The convexity 251 of lockable mechanism 25 is located in the zone of the portion of out-of-position radially outward section of outside slide groove portion section 410 (but with said spacer segment certain clearance), and the cam 252 of lockable mechanism 25 is close to the portion of the out-of-position equally radially outward section of the guide section 430 of face cam 43 respectively.Therefore, lockable mechanism 25 keeps engaging with the tooth portion 31 of second fitting part 3 through face cam 43.
For operable lock locking mechanism 25; Control panel 4 (by through joining the operation of the transmission shaft in the accommodation hole 42 to) rotates round rotation axis A; (in another form of implementation, operation can also be carried out through the rotation along another hand of rotation---being conter clockwise in according to the view of Fig. 1---; Whether the hand of rotation that is used to operate for example can also be arranged on the car door side with Detent fitting 1, perhaps in channel side, promptly is arranged on the automotive seat relevant towards the automobile middle part).At this; The convexity 251 of each lockable mechanism 25 is slided along the outside slide groove portion section 410 of the chute that is associated respectively 41; And the cam 252 that is formed on the lower end of lockable mechanism 25 slides along guide section 430; Up to protruding 251 with outside slide groove portion section 410 radially inwardly out-of-position portion section contact and cam 252 contacts with the radially inside out-of-position portion section of guide section 430; And lockable mechanism 25 radially moves inward (at this, at chute 41 inwardly before the pulling lockable mechanisms 25, according to hysteresis face cam 43 252 certain angles that can release cam) thus.Under this released state, lockable mechanism 25 no longer with 31 engagements of the tooth portion of second fitting part 3, make win fitting part 2 and 3 releases of second fitting part and can be round rotation axis A with respect to 3 rotations of second fitting part.
As shown in Fig. 1, spring element 24 is arranged on first fitting part 2 and is arranged in the accommodation section 23, and remains on first fitting part 2 through holding element 230.Spring element 24 along according to the direction of the lock-out state of Fig. 1 with respect to 2 pairs of face cam 43 prestress of first fitting part; Make that when inoperation face cam 4 Detent fitting 1 remains on lockable mechanism 25 in the latched position and with respect to second fitting part 3 and locks first fitting part 2.
Fig. 2 illustrates the exploded drawings of the form of implementation of Detent fitting 1, and said Detent fitting is equivalent to the Detent fitting 1 according to Fig. 1 basically, and has the embedding ring 6 that is arranged on second fitting part 3 antitorquely.Fig. 3 illustrates the birds-eye view of the assembly of this Detent fitting 1 of being made up of embedding ring 6, lockable mechanism 25a, 25b, 25c and control panel 4, and Fig. 4 A is illustrated in respect to lockable mechanism 25a, 25b, 25c in the different position that embeds ring 6 with Fig. 4 B.
Embed ring 6 and be used to provide and limit the so-called free slewing area of Detent fitting 1, and have free rotation section section 61,63,65 for this reason, said free rotation section section constitutes the section with respect to the radially inside out-of-position portion of the portion's section 62,64,66 that embeds ring 6.
Free rotation section section 61,63,65 and portion's section 62,64,66 constitute the guide-contour on inside edge, the footpath that embeds ring 6 together and constitute, and cooperate in the last convexity 253 of lockable mechanism 25a, 25b, the 25c of Detent fitting 1.Free rotation section section 61,63,65 is embodied as; Make when convexity 253 as lockable mechanism 25a, 25b, 25c is positioned at the angular range of free rotation section section 61,63,65 (seeing Fig. 4 B); Prevent that lockable mechanism 25a, 25b, 25c from can move in the position of radially outer, make them to mesh with the tooth portion 31 on fitting part 3.
Fig. 3 and Fig. 4 A are illustrated in the assembly like the Detent fitting in the upper/lower positions 1; In said position, lockable mechanism 25a, 25b, 25c are arranged in the position of radially outer and mesh (second fitting part 3 with tooth portion 31 is not shown at Fig. 3,4A, 4B) with the tooth portion 31 of second fitting part 3.Under this state, Detent fitting 1 locking; First fitting part 2 can not make and for example can not rotate with respect to seat member through Detent fitting 1 and seat member bonded assembly backrest with respect to 3 rotations of second fitting part.
Through by pass at accommodation hole 42 places rotation face cam 43 and axle that extend along rotation axis A come operation control panel 4 and with control panel 4 bonded assembly face cams 43 (seeing Fig. 4 A); The convexity 251 of lockable mechanism 25a, 25b, 25c is slided along chute 41 respectively; And move to thus in the position of inner radial, and with tooth portion 31 jump out of meshs of second fitting part 3.Remove the locking of Detent fitting 1 from now on; First fitting part 2 can rotate with respect to second fitting part 3.
If in rotational direction S (seeing Fig. 4 A) is with respect to 2 rotations of first fitting part together with embed ring 6 with second fitting part, 3 bonded assemblys antitorquely under this state for second fitting part 3, embedding ring 6 is with respect to lockable mechanism 25a, 25b, 25c motion so.At this, lockable mechanism 25a, 25b, 25c be not through the operation that the continues maintenance of operation board 4 and the jump out of mesh of the tooth portion 31 of second fitting part 3 (wherein the convexity 253 of lockable mechanism 25a, 25b, 25c contacts with the portion's section 62,64,66 that embeds ring 6).
After second fitting part 3 turned an angle with respect to first fitting part 2, the convexity 253 of lockable mechanism 25a, 25b, 25c arrived in the angular range of free rotation section section 61,63,65.This is shown in Fig. 4 B.The tooth portion 250 of this angular range locked 25a of mechanism of section 61,63,65,25b, 25c can not reach engagement with the tooth portion 31 of second fitting part 3 in free rotation section.Therefore, if in this angular regions operation control panel 4 no longer, for example because the unclamp operation bar, so control panel 4 since the prestress of spring 24 tend to get back in the latched position and attempt lockable mechanism 25a, 25b, 25c are radially outward pressed.Yet at this; Lockable mechanism 25a, 25b, 25c reach respectively and the contacting of free rotation section section 61,63,65 through protruding 253; And remain in the position of inner radial through these protruding these, make lockable mechanism can not reach the engagement with the tooth portion 31 of second fitting part 3.Therefore, in the angular range of free rotation section section 61,63,65, prevent the engagement of lockable mechanism 25a, 25b, 25c and tooth portion 31, make Detent fitting 1 to be locked.
Have only when Detent fitting 1 and be rotated further and the convexity 253 of lockable mechanism 25a, 25b, 25c when reaching outside the angular range of free rotation section section 61,63,65; The locking of Detent fitting 1 is only possible; Wherein when the operation of cancelling control panel 4; Because the prestress of spring 24, Detent fitting 1 changes its lock-out state over to.
Use embedding ring 6 to provide free rotation section section 61,63,65 to be implemented in the variable qualification of free slewing area in the Detent fitting.In the identical Detent fitting of this external structure, can use the different embedding ring that adapts to definite application, so that Detent fitting is through independently embedding the application that ring adapts to expectation respectively.
Embedding ring 6 can removably be connected with second fitting part 3.
In order to ensure the smooth version of Detent fitting 1, embed ring 6 and be arranged to relative to each other with control panel 4, feasible same sectional plane E perpendicular to rotation axis A runs through embedding ring 6 and control panel 4, and is as shown in fig. 5.Therefore, embed ring 6 and be arranged on basically in the identical plane, wherein embed and encircle 6 and can have at (on the direction of rotation axis A) different thickness on the axial direction with control panel 4 with control panel 4.In this case, importantly, can have at least one (virtual) cross sectional planes E, it runs through embedding ring 6 and control panel 4.
In the form of implementation shown in Fig. 2 to 5, embed ring 6 and radially be arranged on outside the control panel 4.Therefore control panel 4 radially is positioned at by within the space that embeds ring 6 gauges.
Basically be arranged in the same level with control panel 4 and not axially setting abreast owing to embed ring 6, therefore realize the smooth version of Detent fitting 1.Therefore, embed being arranged on of ring 6 and do not require the additional structural space on the axial direction, and the thickness of Detent fitting 1 on axial direction does not increase.
As visible from Fig. 5, same cross sectional planes E runs through embedding ring 6 and control panel 4, and runs through convexity 251,253 equally, and said convexity protrudes in lockable mechanism 25 on axial direction.Face cam 43 is connected with control panel 4, and axially is connected on the control panel 4 and for operable lock locking mechanism 25, contacts with cam 252 (see figure 1)s of lockable mechanism 25.
As shown in Fig. 6 A and the 6B, embed ring 6 and insert in the accommodation section 34 on second fitting part 3 along the direction of engagement F that is arranged essentially parallel to rotation axis A extension.In the outer circumferential edge that embeds ring 6, form recess 67; Itself and the positioning salient 340 on second fitting part 3 are bonded into; Make that embed ring 6 remains on second fitting part antitorquely, and can not be round rotation axis A with respect to 3 rotations of second fitting part.
The exterior periphery 60 that embeds ring 6 is shaped to, and makes the side face 341 that is different from the boundary of outside qualification accommodation section 34 through the profile of exterior periphery 60, and exterior periphery is different with the shape of the accommodation section that constitutes recess 34.Therefore; Only embedding under the ring 6 slack-free situation; Just possibly be inserted in the accommodation section 34, make to embed ring 6 tensionings in accommodation section 34 under the state that inserts embedding ring 6, and with its exterior periphery 60 with the exterior side face 341 of slack-free mode near accommodation section 34.
Reset force through the embedding ring of for example processing by spring steel 6 under tensioning state; Embed that ring 6 remains in the accommodation section 34 and be fixed under other the situation of measure of accommodation section 34 embedding ring 6 need not being used for, can not from accommodation section 34, skid off easily.
Since embed ring 6 in being inserted into accommodation section 34 time by accommodation section 34 tensionings and be fixed on by this way on second fitting part 3, therefore simplified embedding the installation of ring 6 on second fitting part 3 significantly.Install and especially to reduce to simple insertion process, wherein embed ring 6 and be arranged on second fitting part 3, be positioned on the positioning salient 340 and by the recess 67 that embeds ring at this and be fixed on the accommodation section 34 through tensioning along direction of engagement F.Therefore, embedding ring 6 along the circumferential direction remains on second fitting part 3 with (in contrast to assembly direction F's) axis direction after inserting reliably.
As in according to the view of Figure 12 A and 12B, illustrating to example, embedding ring can the moulding of different ground.
In form of implementation, embed ring 6 and have slightly oval in shape according to Figure 12 A.In order to be inserted in the accommodation section 34, will embed ring resilience ground circumflexion, said circle is corresponding to the circumferential shapes of side face 341 (in Figure 12 A, being shown in broken lines).After inserting, embed ring 6 tensioning and being fixed on second fitting part 3 in accommodation section 34 then.
In replaceable embodiment according to Figure 12 B, embed ring 6 and have (having the angle of rounding) subtriangular external shape, said shape is different with the side face 341 (in Figure 12 B, being shown in broken lines) of the circle of accommodation section 34 again.In this subtriangular embodiment that embeds ring 6, embed that ring 6 especially contacts with side face 341 through its angular zone and by said side face tensioning.
The subtriangular shape that embeds ring 6 causes embedding ring 6 and is divided into three parts; The cyclicity of said three parts is equivalent to three free rotation section sections that provide, and this imports for the power with the cooperating of lockable mechanism 25a, 25b, 25c (seeing Fig. 2 and Fig. 3) time can be favourable.
Can also consider, embed ring 6 and be similar to square shape or pentagon shape or have more polygonal shape.The moulding that embeds ring 6 is random in principle, as long as it is different with the moulding of accommodation section 34 to embed the exterior periphery of ring 6, and embeds therefore in being inserted into accommodation section 34 time and encircles with enough mode tensionings.
The birds-eye view of another form of implementation that embeds ring 6 ' is shown for Fig. 7 A and 7B and along the viewgraph of cross-section of hatching A-A, the end segments 610,630,650 of wherein free rotation section section 61,63,65 is crooked along the direction of rotation axis A.Owing to crooked end section 610,630,650, increased the area of contact of free rotation section section 61,63,65 and protruding 253, make that embedding ring 6 ' can be by processing than thin material.For embedding ring 6 ', for example can use to have the metal sheet that is lower than 1mm thickness.
Fig. 8 illustrates the embedding ring 6 ' according to Fig. 7 A, 7B that cooperates with the convexity 253 of lockable mechanism 25.Because end segments 610 is in axial direction crooked, therefore possible is that embedding encircles 6 ' annular matrix with respect to protruding 253 axial offsets, and only contacts with protruding 253 through end segments 610.Can form the tooth portion 250 of lockable mechanism 25 by this way widelyer, even so that under the situation of big load, also safety and guarantee the locking mesh of the tooth portion 31 of the lockable mechanism 25 and second fitting part 3 reliably.
Embed in the external styling of ring 6 ' again differently, make after inserting, embed ring 6 ' the flexibly tensioning in accommodation section 34 with the moulding of the side face 341 of accommodation section 34.
Embedding ring 6 shown in Fig. 9 " another form of implementation.In this case; Embed ring 6 " under original shape (shown in Fig. 9) exist as the band of forming by elastic plate; and in order to be installed on second fitting part 3; the end 68a, the 68b that embed ring are crooked each other along bending direction B, make to obtain to encircle that said ring is inserted in the accommodation section 34 (seeing Fig. 6 A) of second fitting part 3.
Figure 10 and 11 illustrates the embedding ring of rolling like this 6 " two variant.In first variant according to Figure 10, end 68a, 68b are crooked each other, and embed ring 6 " be arranged on the positioning salient 340 of second fitting part 3 by recess 67.Process by elastic plate owing to embed ring, embed ring 6 " apply reseting elasticity, because said elastic force embeds ring 6 " tensioning and remaining on second fitting part 3 in accommodation section 34, and the axial relief device that need not add.
In second variant, embedding ring 6 according to Figure 11 " on be not provided with independent recess 67.On the contrary, embed ring 6 " end 68a, 68b is crooked and be inserted in the accommodation section 34, makes end 68a, 68b contact with positioning salient 340 and thus antitorque will the embedding encircles 6 " remain in the accommodation section 34 of second fitting part 3.Embed ring 6 " again since the tensioning in accommodation section 34 of its elastic force make need not be used for embedding ring 6 " remain on the additional axial relief mechanism of accommodation section 34.
Be not limited to the embodiment that describes before based on thought of the present invention.On the contrary, can have dissimilar embodiment fully, said embodiment utilization is according to thought of the present invention.For example, can imagine the following form of implementation of Detent fitting, wherein control panel encircles their position of exchange with embedding, so control panel radially is arranged on outside the embedding ring.Wherein, embed ring tensioning on the suitable accommodation section of second fitting part once more.
Detent fitting according to type of the present invention can be used to lock two automotive partss in many ways.Use on automotive seat before only as an example.Yet can imagine the member of other that can will rotate with respect to another automotive parts through this Detent fitting adjustment equally.
