Other forms of implementation of known Detent fitting from DE102006015560B3, DE102006000523A1 and DE10217873B4.
In the time that free rotation section section is provided with embedded rings, there are the following problems, be that embedded rings is arranged on the second fitting part being associated and must determines as additional member, which type of additional installation steps is essential and may makes to install complicated.
Summary of the invention
The object of the invention is, provide that a kind of described Detent fitting is realized the simple installation of embedded rings for locking the Detent fitting of two automotive partss, described embedded rings for limiting free slewing area in the time remaining on safely the fitting part being associated.
This object realizes for the Detent fitting that locks two automotive partss by a kind of, and described Detent fitting, has: the first fitting part, second fitting part that can arrange rotatably with respect to described the first fitting part round rotation axis, the lockable mechanism that at least one can arrange movably on described the first fitting part, described lockable mechanism can engage with the tooth portion of described the second fitting part, for described the first fitting part and described the second fitting part are locked, and described lockable mechanism can depart from and engage with the described tooth portion of described the second fitting part, for unlocking, at least one is arranged on the free rotation section section on described the second fitting part, described free rotation section section is formed on the embedded rings being torsionally arranged on described the second fitting part, and described free rotation section section is arranged to, in the time that described the second fitting part rotates in predetermined angular range with respect to described the first fitting part, coordinate with described lockable mechanism, and the described tooth portion that prevents described lockable mechanism and described the second fitting part engages, it is characterized in that, described embedded rings is inserted in the accommodation section on described the second fitting part, and in the ground tensioning of described accommodation section Elastic.
Correspondingly, embedded rings is inserted in the accommodation section on the second fitting part and in the ground tensioning of accommodation section Elastic.
The present invention is based on following thought, be provided with the embedded rings for limiting free slewing area, described embedded rings is placed on the second fitting part, and by by the flexibly tensioning and being torsionally connected with this second fitting part of the second fitting part.At this, tensioning for example can be carried out as follows, be that the shape of outside circumference of embedded rings is different from the shape of holding profile of the accommodation section that is for example configured to recess of the second fitting part under relaxed state, make embedded rings be matched with the moulding of accommodation section, for being inserted in accommodation section, and correspondingly must tensioning.At this, the distortion of embedded rings is preferably elastomeric, is not plasticity, make to occur enough tensile forces between embedded rings and accommodation section and after shift out from accommodation section embedded rings again get back to its initial, lax shape.
Due to embedded rings tensioning in the time inserting in accommodation section, therefore simplify the installation of embedded rings on accommodation section.Especially do not need for the additional measure at the fixedly embedded ring of the second fitting part (axially), and install also can be overhead top carry out, and embedded rings can not come off after inserting from the second fitting part.Therefore, the installation of embedded rings on the second fitting part reduces to insertion process itself.Do not need other steps for fixedly embedded ring on the second fitting part.
Embedded rings for example can be configured to the ring of sealing, and under the relaxed state before being inserted into accommodation section, the moulding of the exterior periphery of described ring is different from the moulding of accommodation section, and in the situation that inserting, described embedded rings is in the ground tensioning of accommodation section Elastic.In this case, accommodation section is for example configured to the recess with substantially circular side face, and non-circular by the exterior periphery formation of embedded rings, and under lax state, the exterior periphery of embedded rings is different from the moulding of circular side face.Then,, in order to be placed on the accommodation section of the second fitting part, embedded rings is flexibly formed to circle and by the second fitting part tensioning.
In favourable form of implementation, the exterior periphery of embedded rings forms oval and the in the situation that of tensioning, is flexibly inserted in (circle) accommodation section on the second fitting part.But can also consider other moulding of embedded rings, the subtriangular or dimetric moulding that for example (there is the angle of rounding), and therefore cause embedded rings to be divided into widely three parts or four parts.
In replaceable embodiment, embedded rings can also be manufactured by the band of longitudinal extension, and described band to curve ring and is arranged on the second fitting part in order being placed on the accommodation section of the second fitting part.Therefore, embedded rings is not made for the ring of sealing, but be made for the band being formed by least part of elastomeric material, and in the accommodation section being inserted on the second fitting part time, just form annular, and at this, on the second fitting part, be for example configured to tensioning in accommodation section recess, that there is circular outside side face.
Embedded rings can be made and be made up of metal, the blanked part of especially elastomeric spring steel composition.The embedded rings that is configured to the ring of sealing or is configured to band plastic deformation not in the accommodation section being inserted on the second fitting part time, but maintenance elasticity makes embedded rings tensioning and thus because its elastomeric (elastic force) force retaining is on the second fitting part on the second fitting part.
Can be instead likely, in the situation that minimizing cutting loss, embedded rings is made up by (moulding) sintering of its agglomerated material.
Embedded rings can also be manufactured by plastics in principle, wherein must guarantee, the plastic parts of making has enough intensity.
Can also imagine, embedded rings is manufactured by multiple single parts, and described single part is welded to one another, so as therefore to obtain sealing ring or for the suitable band of embedded rings is provided.Can instead also can imagine, multiple parts of embedded rings can be inserted into tensioning separately in the corresponding recess on the second fitting part and in these recesses, make to use each section, the independent free rotation section section of described paragraph qualification on the second fitting part.
Embedded rings for example can removably be connected with the second fitting part, wherein embedded rings has recess in its exterior periphery, described recess can engage with the positioning salient on the second fitting part, for embedded rings is torsionally arranged on the second fitting part.By recess and the positioning salient being associated on the second fitting part, embedded rings is along the circumferential direction fixed on the second fitting part, makes embedded rings torsionally remain on the second fitting part and can not rotate round rotation axis.
Realize and can provide different free rotation section sections with different embedded rings with the independent embedded rings of removably waiting to be fixed on the second fitting part, make the embedded rings by using independent coupling, can set up the Detent fitting for definite use.Therefore the Detent fitting that, this external structure is identical can be by using independent embedded rings to adapt to different situations and requirement.Different embedded rings has different free rotation section sections, and therefore limits the different free slewing area of Detent fitting, and described free slewing area is equivalent to following angular range, and in described angular range, Detent fitting can not be locked.
But replaceable, embedded rings also can be connected with the second fitting part regularly after insertion, for example welding, to be fixed on embedded rings on the second fitting part.
In preferred form of implementation, at least one free rotation section section be configured to the guide-contour that is arranged on the second fitting part with respect at least one other section radially to portion's section of bias internal, coordinate with the projection being associated on lockable mechanism in this for example free rotation section section, wherein in predetermined angular range, in the time that the first fitting part rotates with respect to the second fitting part, projection is arranged in the region of free rotation section section, and because free rotation section section is radially to bias internal, avoid lockable mechanism can move in outside position, footpath and can reach and the engaging of tooth portion on the second fitting part.
In the embodiment of embedded rings, at least one free rotation section section is bent to has the end segment that is parallel to described rotation axis (A).Free rotation section section be configured to embedded rings radially to portion's section of bias internal, and in axial direction bending in the radially inner end segment of free rotation section section.Thus, increase free rotation section section and the protruding area of contact on lockable mechanism, or free rotation section section is in axial direction towards projection guiding, to cause that free rotation section section contacts with projection.
In principle, as the Detent fitting of invention of here introducing can have one, two, three, four or more lockable mechanism also.But in favourable form of implementation, Detent fitting has three lockable mechanisms, they are associated with free rotation section section respectively.Therefore on the first fitting part, be provided with movably three lockable mechanisms, and on the second fitting part, torsionally form three free rotation section sections.Three lockable mechanisms in engaging with the tooth portion of the second fitting part, and can radially to move in order unlocking and therefore to depart from and engage with the tooth portion of the second fitting part under the lock-out state of Detent fitting on the second fitting part.

Detailed description of the invention
Fig. 1 illustrates the transparent view that the part of the form of implementation of Detent fitting 1 is dissectd, described Detent fitting for example can be in the time that seat be adjusted for adjusting the inclination angle of backrest of automotive seat.At this, the identical Detent fitting 1 of structure in backrest both sides axially the pivot center along backrest be offset each other and arrange, and be connected to each other by the transmission shaft extending along rotation axis A.Detent fitting 1 locks backrest for the seat member with respect to automotive seat, and under lock-out state, backrest is remained on the position with respect to seat member.Can operate transmission shaft connected to one another Detent fitting 1 by control lever, to unlock thus Detent fitting 1 and adjustment backrest.
Detent fitting 1 shown in Figure 1 has the first fitting part 2, and it is connected with the second fitting part 3 around rotation axis A rotationally by the retaining ring 5 being arranged on the first fitting part 2.First retaining ring 5 for example can install by gap, and then welds with the first fitting part 2.When locking backrest, the first fitting part 2 for example can be connected with seat member and the second fitting part 3 can be connected with backrest, and wherein the pivot center between backrest and seat member is corresponding to the rotation axis A of Detent fitting 1.
In order to lock, on the first fitting part 2, arrange three and be offset each other the lockable mechanism 25 of 120 ° round S. A. A, it is radially adjusted direction V by director element 21,22 and is arranged on movably on the first fitting part 2, and engages in order to lock the tooth portion 31 that Detent fitting 1 can be the internal tooth portion in annular section 33 with the formation of the second fitting part 3 by outside tooth portion 250.
Under state shown in Figure 1, lockable mechanism 25 is in radially outward mobile position, and in described position, the tooth portion 250 of lockable mechanism engages with the tooth portion 31 of the second fitting part 3.Under this state, Detent fitting 1 locks, and the first fitting part 2 can not be rotated with respect to the second fitting part 3.
According in the form of implementation of Fig. 1, radially guide the director element 21,22 of lockable mechanism 25 be configured to projection, towards the second fitting part 3 from the outstanding portion's section of disc shaped matrix 20, and on the one hand for radial directed lockable mechanism 25 and on the other hand for the first fitting part 2 is bearing in to the second fitting part 3.For this reason, the outer segments 211,221 of director element 21,22 is close to the formation of the second fitting part 3 as the tooth portion 31 of internal tooth portion in the mode of sliding, and the first fitting part 2 can be rotated with respect to the second fitting part 3 around rotation axis A.
The locking of Detent fitting 1 forms by lockable mechanism 25, and described lockable mechanism engages with the tooth portion 31 of the second fitting part 3 by tooth portion 250 under lock-out state.In this case, operable lock locking mechanism 25 locks Detent fitting 1 or unlocks and can be undertaken by the control panel 4 being arranged between the first fitting part 2 and the second fitting part 3, described control panel is configured to disc, and has for shape and engage and be contained in the center accommodation hole 42 of recess 27,32 places through the transmission shaft of fitting part 2,3.
On control panel 4, form and be offset each other the identical chute 41 of structure of 120 ° around rotation axis A, the projection 251 of lockable mechanism 25 joins to respectively in described chute.Projection 251 is close to respectively the outside slide groove portion section 410 of chute 41, and slides along outside slide groove portion section 410 in the time that control panel 4 rotates around rotation axis A.
The face cam 43(of the projection that the mode that is provided with to give prominence on control panel 4 and at dorsal part forms is shown in Fig. 2), described face cam forms and has guide section 430 in its exterior periphery, and described guide section contacts with the lockable mechanism 25 being arranged on the first fitting part 2 by the cam 252 being formed in respectively on the bottom of lockable mechanism 25.
Under lock-out state,---under this state, lockable mechanism 25 radially outward moves and engages with the tooth portion 31 of the second fitting part 3 by its tooth portion 250---, the projection 251 of lockable mechanism 25 is located in the region of portion's section of radially outward skew of outside slide groove portion section 410 (but gap certain with described portion spacer segment), and the cam 252 of lockable mechanism 25 is close to respectively equally radially outward portion's section of skew of the guide section 430 of face cam 43.Therefore, lockable mechanism 25 keeps engaging with the tooth portion 31 of the second fitting part 3 by face cam 43.
For operable lock locking mechanism 25, control panel 4(is by by the operation that joins the transmission shaft in accommodation hole 42 to) rotate round rotation axis A,---according to being conter clockwise in the view of Fig. 1---(in another form of implementation, operation can also be undertaken by the rotation along another hand of rotation; For example can also whether be arranged on vehicle door side with Detent fitting 1 for the hand of rotation operating, or in channel side, be arranged on automotive seat relevant towards automobile middle part).At this, the projection 251 of each lockable mechanism 25 is slided along the outside slide groove portion section 410 of the chute 41 being associated respectively, and the cam 252 being formed in the lower end of lockable mechanism 25 slides along guide section 430, until radially the contacting and projection 251 from radially the contacting to portion's section of bias internal of cam 252 and guide section 430 to portion's section of bias internal and outside slide groove portion section 410, and lockable mechanism 25 radially moves inward (at this thus, before chute 41 inwardly pulls lockable mechanism 25, according to hysteresis face cam 43 252 certain angles that can release cam).Under this released state, lockable mechanism 25 no longer engages with the tooth portion 31 of the second fitting part 3, makes the first fitting part 2 and the second fitting part 3 releases and can rotate with respect to the second fitting part 3 round rotation axis A.
As shown in Figure 1, spring element 24 is arranged on the first fitting part 2 and is arranged in accommodation section 23, and remains on the first fitting part 2 by holding element 230.Spring element 24 along according to the direction of the lock-out state of Fig. 1 with respect to the first fitting part 2 to face cam 43 prestress, make in the time of inoperation face cam 4, Detent fitting 1 remains on lockable mechanism 25 in latched position and with respect to the second fitting part 3 and locks the first fitting part 2.
Fig. 2 illustrates the exploded drawings of the form of implementation of Detent fitting 1, and described Detent fitting is equivalent to the Detent fitting 1 according to Fig. 1 substantially, and has the embedded rings 6 being torsionally arranged on the second fitting part 3.Fig. 3 illustrates the birds-eye view of the assembly of this Detent fitting 1 being made up of embedded rings 6, lockable mechanism 25a, 25b, 25c and control panel 4, and Fig. 4 A and Fig. 4 B are illustrated in respect to lockable mechanism 25a, 25b, 25c in the different position of embedded rings 6.
Embedded rings 6 is for providing and limit the so-called free slewing area of Detent fitting 1, and has free rotation section section 61,63,65 for this reason, and described free rotation section section is configured to respect to portion's section 62,64,66 of embedded rings 6 radially to portion's section of bias internal.
Free rotation section section 61,63,65 is configured to the guide-contour on inside edge, the footpath of embedded rings 6 and is configured to together with portion section 62,64,66, coordinates with the projection 253 on lockable mechanism 25a, 25b, 25c at Detent fitting 1.Free rotation section section 61,63,65 is embodied as, make (to see Fig. 4 B) in the time that the projection 253 of lockable mechanism 25a, 25b, 25c is positioned at the angular range of free rotation section section 61,63,65, prevent that lockable mechanism 25a, 25b, 25c from can move in the position of radially outer, they can not be engaged with the tooth portion 31 on fitting part 3.
Fig. 3 and Fig. 4 A are illustrated in as the assembly of the Detent fitting 1 in upper/lower positions, in described position, lockable mechanism 25a, 25b, 25c are arranged in the position of radially outer and engage (second fitting part 3 with tooth portion 31 is not shown at Fig. 3,4A, 4B) with the tooth portion 31 of the second fitting part 3.Under this state, Detent fitting 1 locks; The first fitting part 2 can not rotate with respect to the second fitting part 3, and the backrest being for example connected with seat member by Detent fitting 1 can not be rotated with respect to seat member.
By seeing Fig. 4 A by carrying out operation control panel 4 at accommodation hole 42 places through the rotation of axle face cam 43 and that extend along rotation axis A with the face cam 43(being connected with control panel 4), the projection 251 of lockable mechanism 25a, 25b, 25c is slided along chute 41 respectively, and move to thus in the position of inner radial, and depart from and engage with the tooth portion 31 of the second fitting part 3.,, remove the locking of Detent fitting 1 from now on; The first fitting part 2 can rotate with respect to the second fitting part 3.
If the second fitting part 3 under this state together with the embedded rings 6 being torsionally connected with the second fitting part 3 in rotational direction S(see Fig. 4 A) rotate with respect to the first fitting part 2, embedded rings 6 is with respect to lockable mechanism 25a, 25b, 25c motion so.At this, lockable mechanism 25a, 25b, 25c are by the lasting operation maintenance of operation board 4 and the disengaging engagement (wherein the projection 253 of lockable mechanism 25a, 25b, 25c does not contact with portion's section 62,64,66 of embedded rings 6) of the tooth portion 31 of the second fitting part 3.
After the second fitting part 3 turns an angle with respect to the first fitting part 2, the projection 253 of lockable mechanism 25a, 25b, 25c arrives in the angular range of free rotation section section 61,63,65.This is shown in Fig. 4 B.In this angular range of free rotation section section 61,63,65, the tooth portion 250 of lockable mechanism 25a, 25b, 25c can not reach and engage with the tooth portion 31 of the second fitting part 3.Therefore, if in this angular regions operation control panel 4 no longer, for example, because unclamp operation bar, control panel 4 is because the prestress of spring 24 tends to get back in latched position and attempts lockable mechanism 25a, 25b, 25c radially outward to press so.But at this, lockable mechanism 25a, 25b, 25c reach respectively and the contacting of free rotation section section 61,63,65 by projection 253, and these remain in the position of inner radial by these projections, lockable mechanism can not be reached and the engaging of the tooth portion 31 of the second fitting part 3.Therefore, in the angular range of free rotation section section 61,63,65, prevent that lockable mechanism 25a, 25b, 25c from engaging with tooth portion 31, make the Detent fitting 1 can not be locked.
Only have and be rotated further and when the projection 253 of lockable mechanism 25a, 25b, 25c reaches outside the angular range of free rotation section section 61,63,65 when Detent fitting 1, the locking of Detent fitting 1 is only possible, wherein in the time of the operation of cancelling control panel 4, due to the prestress of spring 24, Detent fitting 1 proceeds to its lock-out state.
Control panel 4 and face cam 43 can be formed integrally as a member, but can also form and be connected and be connected to each other by the connector that for example shape engages in two parts ground.
The variable restriction of free rotation section section 61,63,65 realizations free slewing area in Detent fitting is provided with embedded rings 6.In the identical Detent fitting of this external structure, can use the different embedded rings that adapts to definite application, so that Detent fitting adapts to respectively the application of expectation by embedded rings independently.
Embedded rings 6 can removably be connected with the second fitting part 3.
In order to ensure the smooth version of Detent fitting 1, embedded rings 6 and control panel 4 are arranged to relative to each other, make to run through embedded rings 6 and control panel 4 perpendicular to the same sectional plane E of rotation axis A, as shown in fig. 5.Therefore, embedded rings 6 and control panel 4 are arranged in identical plane substantially, and wherein embedded rings 6 and control panel 4 can have in the axial direction (in the direction of rotation axis A) different thickness.In this case, importantly, can have at least one (virtual) cross sectional planes E, it runs through embedded rings 6 and control panel 4.
In the form of implementation shown in Fig. 2 to 5, embedded rings 6 is radially arranged on outside control panel 4.Therefore within control panel 4 is radially positioned at the space by embedded rings 6 gauges.
Axially arrange abreast because embedded rings 6 and control panel 4 are arranged in same level and not substantially, therefore realize the smooth version of Detent fitting 1.Therefore, the setting of embedded rings 6 does not require additional structure space in the axial direction, and Detent fitting 1 thickness in the axial direction does not increase.
As can be seen from Fig. 5, same cross sectional planes E runs through embedded rings 6 and control panel 4, and runs through equally projection 251,253, and described projection protrudes from lockable mechanism 25 in the axial direction.Face cam 43 is connected with control panel 4, and is axially connected on control panel 4 and for operable lock locking mechanism 25, sees Fig. 1 with the cam 252(of lockable mechanism 25) contact.
Embedded rings 6 for example can be made for the blanked part being made up of metal, or is made for the sintered part that (moulding) sintering forms in the situation that avoiding cutting loss, or having under the prerequisite of enough intensity, also can be made up of plastics.But preferably, embedded rings 6 is by hardened steel, especially spring steel forms, so that the load when being absorbed in reliably and safely Detent fitting 1 and working.
Shown at Fig. 6 A and 6B, embedded rings 6 inserts in the accommodation section 34 on the 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 of embedded rings 6, form recess 67, it is bonded into the positioning salient 340 on the second fitting part 3, embedded rings 6 is torsionally remained on the second fitting part, and can not rotate with respect to the second fitting part 3 round rotation axis A.
The exterior periphery 60 of embedded rings 6 is shaped to, and makes to be different from by the profile of exterior periphery 60 side face 341 of the boundary of outside restriction accommodation section 34, and exterior periphery is different from the shape of accommodation section 34 that is configured to recess.Therefore, only the in the situation that of embedded rings 6 tensioning, just embedded rings 6 may be inserted in accommodation section 34, make embedded rings 6 tensioning in accommodation section 34 under the state inserting, and with its exterior periphery 60 in the mode of tensioning the outside side face 341 near accommodation section 34.
By the reset force of the embedded rings of for example being made by spring steel 6 under tensioning state, embedded rings 6 remains in accommodation section 34 and, other the measure for embedded rings 6 being fixed on to accommodation section 34, can not from accommodation section 34, skid off easily in the case of not needing.
Due to embedded rings 6 in the time being inserted in accommodation section 34 by accommodation section 34 tensionings and be fixed on by this way on the second fitting part 3, therefore simplified significantly the installation of embedded rings 6 on the second fitting part 3.Install and especially reduce to simple insertion process, wherein embedded rings 6 is arranged on the second fitting part 3 along direction of engagement F, and the recess 67 at this by embedded rings is positioned on positioning salient 340 and by tensioning and is fixed on accommodation section 34.Therefore, embedded rings 6 along the circumferential direction remains on reliably on the second fitting part 3 with (in contrast to assembly direction F's) axis direction after inserting.
As according to illustratively illustrating in the view of Figure 12 A and 12B, embedded rings is moulding differently.
According in the form of implementation of Figure 12 A, embedded rings 6 has slightly oval-shaped shape.In order to be inserted in accommodation section 34, by flexibly circumflexion of embedded rings, described circle is shown in broken lines in Figure 12 A corresponding to side face 341() circumferential shapes.After inserting, then embedded rings 6 tensioning and being fixed on the second fitting part 3 in accommodation section 34.
According in the replaceable embodiment of Figure 12 B, embedded rings 6 has (with the angle of rounding) subtriangular outer shape, and described shape is shown in broken lines in Figure 12 B from the circular side face 341(of accommodation section 34 again) different.In this subtriangular embodiment of embedded rings 6, embedded rings 6 especially contacts with side face 341 by its angular zone and by described side face tensioning.
The subtriangular shape of embedded rings 6 causes embedded rings 6 to be divided into three parts, three free rotation section sections that provide are provided the cyclicity of described three parts, and this is for seeing Fig. 2 and Fig. 3 with lockable mechanism 25a, 25b, 25c() coordinate time power to import can be favourable.
Can also consider, embedded rings 6 is similar to square shape or pentagon shape or has more polygonal shape.The moulding of embedded rings 6 is random in principle, as long as the exterior periphery of embedded rings 6 is different from the moulding of accommodation section 34, and therefore in the time being inserted in accommodation section 34 embedded rings with enough mode tensionings.
Fig. 7 A and 7B illustrate embedded rings 6 ' another form of implementation birds-eye view and along the viewgraph of cross-section of hatching A-A, wherein the end segment 610,630,650 of free rotation section section 61,63,65 is along the direction bending of rotation axis A.Due to crooked end section 610,630,650, increase the area of contact of free rotation section section 61,63,65 and projection 253, embedded rings 6 ' can be made up of thinner material.For embedded rings 6 ', for example, can use the metal sheet having lower than 1mm thickness.
Fig. 8 illustrate coordinate with the projection 253 of lockable mechanism 25 according to the embedded rings 6 ' of Fig. 7 A, 7B.Because end segment 610 is in axial direction bending, therefore possible that, the annular matrix of embedded rings 6 ' is with respect to protruding 253 axial offsets, and only contacts with protruding 253 by end segment 610.Can form by this way the tooth portion 250 of lockable mechanism 25 widelyr, even so that in the case of large load, also safety and guarantee reliably the locking mesh of the tooth portion 31 of lockable mechanism 25 and the second fitting part 3.
Different from the moulding of the side face 341 of accommodation section 34 again in the external styling of embedded rings 6 ', make after inserting, embedded rings 6 ' is in accommodation section 34 Elastics ground tensionings.
Embedded rings 6 ' shown in Figure 9 ' another form of implementation.In this case, embedded rings 6 ' ' under original shape (shown in Figure 9) exist as the band that formed by elastic plate, and in order to be arranged on the second fitting part 3, end 68a, the 68b of embedded rings is mutually bending along bending direction B, make to obtain ring, the accommodation section 34(that described ring is inserted into the second fitting part 3 is shown in Fig. 6 A) in.
Figure 10 and 11 illustrates the embedded rings 6 ' of rolling like this ' two form of distortion.According in the first form of distortion of Figure 10, end 68a, 68b are mutually bending, and embedded rings 6 ' ' be arranged on by recess 67 on the positioning salient 340 of the second fitting part 3.Because embedded rings is made up of elastic plate, embedded rings 6 ' ' apply reseting elasticity, due to described elastic force, embedded rings 6 ' ' tensioning and remaining on the second fitting part 3 in accommodation section 34, and do not need additional axial relief device.
According in the second form of distortion of Figure 11, at embedded rings 6 ' ' on be not provided with independent recess 67.On the contrary, embedded rings 6 ' ' end 68a, 68b bending and be inserted in accommodation section 34, end 68a, 68b are contacted with positioning salient 340 and thus torsionally by embedded rings 6 ' ' remain in the accommodation section 34 of the second fitting part 3.Embedded rings 6 ' ' again due to the tensioning in accommodation section 34 of its elastic force, make not need for by embedded rings 6 ' ' remains on the additional axial relief mechanism of accommodation section 34.
The embodiment describing before being not limited to based on thought of the present invention.On the contrary, can have dissimilar embodiment completely, described 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 and their position of embedded rings exchange, therefore control panel is radially arranged on outside embedded rings.Wherein, embedded rings tensioning on the suitable accommodation section of the second fitting part again.
Can be in many ways for locking two automotive partss according to the Detent fitting of type of the present invention.Use on automotive seat is only as example before.But can imagine equally the member of other that can will rotate with respect to another automotive parts by this Detent fitting adjustment.
