Definitions
- the invention relates to a lock arrangement, in particular for vehicle doors or vehicle flaps, with a lock housing, a rotary latch rotatably mounted on the lock housing, which can be moved into a latching position for locking the vehicle door or vehicle flap and an open position for releasing the vehicle door or vehicle flap, and a pawl pivotably mounted on the lock housing, which can be moved between a locking position securing the rotary latch in its latching position and a release position releasing the rotary latch, wherein the pawl is designed to block a rotary movement of the rotary latch in the direction of the open position in the locked position, and wherein the pawl is designed to block a rotary movement of the rotary latch in a direction opposite to the open position in the locked position.
- a locking device which has a snap lock comparable to a rotary latch and rotatably mounted with a receptacle for a locking bolt and a blocking pawl comparable to a locking pawl, which is also rotatably mounted and which keeps the snap lock locked when the snap lock is arranged in a closed position in which the snap lock holds the locking bolt.
- a first blocking surface and a second blocking surface are formed on the blocking pawl, which are arranged diverging in a direction pointing away from the blocking pawl.
- a lock arrangement of the type described above is known, for example, from US2015/376919 A1 , the JP 2004 238841 A and the JP 2005 161987 A known, wherein furthermore a lock arrangement from the EN 10 2012 102 724 A1 is known which is a rotary latch and a rotary latch in a Has a pawl that holds the catch in the locked position, the rotary latch and the pawl being rotatably mounted on a lock housing.
- a locking bolt that falls into the mouth of the rotary latch ensures that the rotary latch is rotated from its open position into its locked position, with the rotary latch engaging with the pawl during this rotary movement.
- the rotary latch When the rotary latch is in the locked position, the rotary latch can only move back into its open position when the pawl is moved from its locked position to its release position, which is achieved with the aid of a drive element provided for this purpose. When the rotary latch is in the locked position, however, the rotary latch can rotate into an over-stroke position that goes beyond the locked position, which creates play in the pawl and allows the rotary latch to move relative to the locking bolt, which causes a rattling noise that the user can hear.
- the sealing forces are low, meaning that very little to no tension is exerted on the lock assembly of the rotary latch and pawl, which allows the rotary latch to rotate into the over-travel position described above, which leads to the described and undesirable rattling noise.
- the EN 10 2012 102 724 A1 A solution is known from the known lock arrangement in which a rotatably mounted immobilizing element is provided on the lock housing, which ensures that when the rotary latch is in the locked position, the locking bolt is clamped between the rotary latch and the lever-shaped immobilizing element, so that a relative movement of the locking bolt in relation to the rotary latch, which is the cause of the annoying rattling noise, is prevented.
- the disadvantage of this known lock arrangement is that an additional component is required for immobilization, which This results in higher manufacturing costs and reduced compactness of the lock arrangement.
- the invention is based on the object of developing a lock arrangement in a structurally simple and cost-effective manner, in which undesirable noise development is avoided and which is characterized by a compact design.
- this object is achieved according to the invention in that a hook-shaped pawl section is formed on one longitudinal end of the pawl, which has a first locking surface, and in that the rotary latch has a radially protruding locking element with a first contact surface, wherein in the locking position the pawl with its pawl section engages under the locking element on the first contact surface and the pawl with the first locking surface rests on the first contact surface at least in sections such that a rotary movement of the rotary latch in the direction of the open position is blocked, wherein the pawl has a second locking surface spaced from the first locking surface, wherein the rotary latch has a second contact surface spaced from the first contact surface, and wherein in the locking position the pawl with the second locking surface rests on the second contact surface at least in sections such that a rotary movement of the rotary latch in a direction opposite to the open position is blocked, and wherein the first locking surface and the second locking surface are in that
- the invention provides a lock arrangement in a structurally simple and cost-effective manner, which is characterized by a simple and compact design and yet effectively prevents a rotational movement of the rotary latch from its locking position in both directions of rotation when the pawl is arranged in its locking position. Because the pawl prevents a rotational movement of the rotary latch into an over-travel position beyond the locking position at a time when the pawl is arranged in its locking position, the problem of undesirable rattling noise known from the prior art is effectively avoided.
- the invention is characterized by a purely mechanical solution which, in contrast to known lock arrangements from the prior art, does not require an additional component, such as a lever-shaped immobilization element, and does not require any rubber-like and wear-prone buffer elements.
- the locking element of the rotary latch is designed as a tooth-shaped projection that protrudes radially from the rotary latch and that the pawl section of the locking pawl has a mouth-shaped recess that is matched to the tooth-shaped projection of the rotary latch, wherein in the locking position the tooth-shaped projection of the rotary latch is arranged at least partially within the mouth-shaped recess of the pawl.
- the mouth-shaped pawl section of the locking pawl and the tooth-shaped projection of the rotary latch form a positive connection in the locking position of the pawl and in the locking position of the rotary latch, by means of which the rotary latch can be moved both into its open position and into one of the
- the jaw-shaped recess is matched to the tooth-shaped projection in such a way that the functionality is guaranteed both for the wedge effect required in the locked position and for easy release of the rotary latch and pawl when the vehicle door is opened.
- first contact surface and the second contact surface of the rotary latch are side flanks of the tooth-shaped projection facing away from one another. Accordingly, the first locking surface and the second locking surface are aligned facing an interior of the mouth-shaped recess and are arranged opposite one another and facing one another.
- the rotary latch and the locking pawl thus have a structurally simple shape that can be manufactured inexpensively using known manufacturing processes.
- the tooth-shaped projection and the mouth-shaped recess are coordinated with one another in such a way that a wedge-shaped interlock occurs between the tooth-shaped projection and the mouth-shaped recess in the locking position.
- a wedge-shaped interlock occurs between the tooth-shaped projection and the mouth-shaped recess in the locking position.
- the pawl and the rotary latch wedge together while a motor vehicle is driving, which prevents rattling noises.
- it is particularly advantageous in the design for the first embodiment if the first contact surface and the second contact surface are arranged in the direction of the pawl at a contact surface angle of between 5° and 15°, diverging from one another.
- a design for a second embodiment provides that the first contact surface is formed opposite the second contact surface, wherein the rotary latch has a contact recess which is arranged and formed adjacent to the first contact surface, wherein the second contact surface forms at least one wall section of the contact recess.
- the contact recess has a contact contour coordinated with the hook-shaped latch section, so that in the locking position, at least in sections, the first locking surface rests on the first contact surface and at least in sections, the second locking surface rests on the second contact surface in such a way that a rotational movement of the rotary latch in the direction of the open position and in a direction opposite to the open position, i.e. an overstroke position, is blocked.
- first contact surface and the second contact surface are arranged diverging from one another in the direction of the pawl at a contact surface angle of between 75° and 85°.
- first locking surface is longer than the second locking surface. This ensures that the wedge effect is present in the locked position and that the rotary latch and pawl are easily released when the rotary latch is to be moved into its open position. It also has a positive effect on functional reliability in both embodiments if the first contact surface is longer than the second contact surface.
- first contact surface and the second contact surface are arranged in the direction of the pawl at a contact surface angle that diverges from one another.
- first locking surface and the second locking surface are arranged in a direction away from the rotary latch, diverging from one another at a locking surface angle.
- one embodiment provides that in the locking position the first locking surface is arranged parallel to the first contact surface, with the first locking surface and the second locking surface being designed to diverge in the direction of the rotary latch. It is also advantageous if in the locking position the first locking surface is arranged parallel to the first contact surface, with the distance between the first locking surface and the second locking surface increasing in the direction of the rotary latch.
- the first locking surface is not designed parallel to the first contact surface, but that at least one of the surfaces (locking surface(s) and/or contact surface(s)) is a surface designed in a radius, in which the radii of the surfaces (locking surface(s) and/or contact surface(s)) have the same radius, but the radius centers are offset from one another, so that there is only linear contact between the locking surface and the contact surface.
- the offset of the radius centers also means that the locking pawl is always pulled into the locking position by the rotary latch, which pushes it into the open position.
- the rotary latch In order to rotate the rotary latch from its locking position to the open position, the rotary latch is spring-loaded in the direction of its open position. In this way, a motor drive to move the rotary latch is not necessary.
- a further embodiment provides that the pawl is spring-loaded in the direction of its locking position with the aid of a spring element.
- the spring element In the locking position, the spring element thus always pushes the hook-shaped pawl section of the pawl in the direction of the rotary latch, so that the clamping effect between the pawl section of the pawl and the rotary latch is supported by the spring element.
- One leg of the spring element is supported on the lock housing, whereas the other leg of the spring element rests, for example, on a pawl attachment of the pawl.
- FIG 1 a motor vehicle 1 in the form of a car is shown as an example, which in the example has a flap or tailgate 2 that can be closed and opened via a lock arrangement 3.
- the Figure 2 shows a perspective view of the Figure 1 merely exemplary lock arrangement 3, whereas in Figure 3 the lock arrangement is shown in a single part view.
- Figures 4 to 11 For reasons of clarity, a representation of a Figures 2 and 3 visible lock housing 4.
- the Figures 2 and 3 show the lock arrangement 3, in which a locking bolt (not shown in detail in the figures and arranged in a fixed position on the motor vehicle 1) interacts with a rotary latch mouth 5 of a rotary latch 6, wherein in the closed position of the lock arrangement 3 the locking bolt is caught in the rotary latch mouth 5 of the rotary latch 5 and the rotary latch 5 is in engagement with a pawl 7 so that the tailgate 2 is locked, whereas the tailgate 2 can be swung open when the rotary latch 5 and the pawl 7 are disengaged and the locking bolt can move out of the rotary latch mouth 5.
- a reverse arrangement is also conceivable, in which the lock arrangement 3 is fixed in a fixed position on the motor vehicle 1 and the locking bolt can move with the tailgate 2.
- the lock arrangement 3 comprises the rotary latch 6, which is mounted on the lock housing 4 so as to be rotatable about a rotation axis 8 (see Figure 2 ).
- the rotary latch 6 is arranged in a locking position, which is a position for locking the vehicle flap 2.
- the rotary latch 6 is spring-loaded in the direction of its open position. This means that, for example, a spring exerts a force on the rotary latch 6 to push the rotary latch 6 into the open position when the rotary latch 6 is arranged in the locking position.
- the pawl 7 holds the rotary latch 6 in its locking position when the pawl 7 is arranged in a locking position (see Figure 2 ).
- the pawl 7 is pivotably mounted on the lock housing 4 via a pivot axis 9 and can be moved between the locking position, in which the pawl 7 secures the rotary latch 6 in its locking position, and a release position that releases the rotary latch 6.
- the pivot axis 9 itself is pivotably mounted on the lock housing 4 by means of a movement element 10 is movably attached to the lock housing 4.
- a merely Figure 2 shown spring element 11 on the pawl 7 and pushes a free longitudinal end 14 of the pawl 7, which is designed as a hook-shaped pawl section 12, in the direction of the rotary latch 6.
- the spring element 11 thus ensures that the pawl 7 is spring-loaded from its release position towards its locking position with the aid of the spring element 11.
- a first leg 11a of the spring element 11 is supported on the lock housing 4, whereas a second leg 11b of the spring element 11 rests on a pawl pin 7a of the pawl and exerts a force on the pawl 6 acting in the direction of the rotary latch 7 via the pawl pin 7a.
- the hook-shaped latch section 12 has a first locking surface 15. Furthermore, a radially protruding locking element 16 (see Figure 2 ) which has a first contact surface 17.
- the first locking surface 15 enables the pawl 7, when arranged in the locking position, to rotate the rotary latch 6 in the direction of the open position (see arrow 18 in Figure 4 ) is designed to block, in that in the blocking position the pawl 7 with its pawl section 12 engages under the locking element 16 on the first contact surface 17 and the pawl 7 with the first blocking surface 15 rests at least partially on the first contact surface 17 in such a way that a rotational movement of the rotary latch 6 in the direction of the open position is blocked.
- the first blocking surface 15 and the first contact surface 17 are not in complete contact with each other in the blocking position or the locking position. Rather, the first blocking surface 15 rests at least partially on the first contact surface 17, as is the case for various states in the Figures 6 to 8 is shown, whereby also states are conceivable in which the first contact surface 17 rests completely against the first blocking surface 15.
- the first locking surface 15 of the pawl 7 is designed with a greater length 19 than the length 29 of the first contact surface 17 of the rotary latch 6.
- the length 19 of the first locking surface 15 is designed to be greater than the length 20 of the second locking surface 21 (see Figure 5 ).
- the length 29 of the first contact surface 17 is larger than the length 30 of the second contact surface 22 (see Figure 4 ).
- the pawl 7 in the locking position causes a rotational movement of the rotary latch 6 in a direction opposite to the open position (see arrow 23 in Figure 4 ) is designed to block.
- the locking pawl 7 has a second locking surface 21 spaced from the first locking surface 15, whereas the rotary latch 6 has a second bearing surface 22 spaced from the first contact surface 17.
- the locking pawl 7 rests with the second locking surface 21 on the second contact surface 22 at least in sections in such a way that a rotational movement of the rotary latch 6 in the direction 23 opposite to the open position is blocked.
- the locking element 16 of the rotary latch 6 is designed as a tooth-shaped projection 24 that protrudes radially from the rotary latch 6.
- the pawl section 12 of the locking pawl 7 has, in the first embodiment, a mouth-shaped recess 25 that is matched to the tooth-shaped projection 24 of the rotary latch 6.
- the tooth-shaped projection 24 of the rotary latch 6 is dimensioned such that when the locking pawl 7 moves from the release position to the locking position, the mouth-shaped recess 25 receives and surrounds the tooth-shaped projection 24 of the rotary latch 6 at least in sections without friction and without contact, and that when the locking pawl 7 moves from the locking position to the In the release position, the pawl 7 and the rotary latch 7 can easily be released from one another and disengaged.
- the tooth-shaped projection 24 of the rotary latch 6 is arranged at least partially within the mouth-shaped recess 25 of the pawl 7.
- first contact surface 17 and the second contact surface 2 of the rotary latch 6 form side flanks 24a and 24b of the tooth-shaped projection 24 facing away from one another.
- first blocking surface 15 and the second blocking surface 21 are aligned facing an interior 26 of the mouth-shaped recess 25 and are arranged opposite one another and facing one another, as shown in Figure 5 is shown.
- a jamming occurs between the tooth-shaped projection 24 of the rotary latch 6 and the mouth-shaped recess 25 of the pawl 7 when the pawl 7 is arranged in its locking position and the projection 24 is arranged at least partially in the recess 25.
- a minimal movement of the rotary latch 6, which is less than the movement tolerance given by the elastic flap seal leads to a wedging of the tooth-shaped projection 24 in the mouth-shaped recess 25, as is shown in the Figures 6 to 8 for different relative positions of the rotary latch 6 to the locking pawl 7.
- the clamping or wedging of the projection 24 and the recess 25, but also the release of this clamping to release the tailgate 2, is facilitated by the fact that the first contact surface 17 and the second contact surface 22 are arranged in the direction of the locking pawl 7 at a contact surface angle 27 between 5° and 15° diverging from one another (see Figure 4 ).
- the contact surface angle 27 is preferably 10°.
- Jamming or wedging of the projection 24 and the recess 25 is further promoted if the first locking surface 15 and the second locking surface 21 are in a direction away from the rotary latch 6.
- Direction are arranged diverging from one another at a blocking surface angle 28.
- the blocking surface angle 28 is smaller than the contact surface angle 27.
- the respective dashed line which marks the course of the first blocking surface 15 or the first contact surface 17 has been shifted parallel to the dashed line which marks the course of the second blocking surface 21 or the second contact surface 22.
- first locking surface 15 in the locking position is arranged parallel to the first contact surface 17, wherein the first locking surface 15 and the second locking surface 21 are designed to diverge in the direction of the rotary latch 6.
- first locking surface 15 in the locking position is arranged parallel to the first contact surface 17, wherein the distance 50 between the first locking surface 15 and the second locking surface 21 increases in the direction of the rotary latch 6.
- the hooking which can also be referred to as jamming or wedging, is for the Figures 6 to 8 shown states characterized in that in the locking position both the first locking surface 15 rests at least partially on the first contact surface 17 and the second locking surface 21 rests at least partially on the second contact surface 22 so that both a rotary movement of the rotary latch 6 in the direction of the open position 18 is blocked and a rotary movement of the rotary latch 6 in the direction opposite to the open position 23 is blocked.
- the described wedge effect or wedge interlock ensures that the rotary latch 6 cannot rotate at all about the axis of rotation 8 when the rotary latch 6 is in the locked position and the pawl 7 is in the locked position.
- the Figures 9 to 11 show a second embodiment of the present invention.
- the second embodiment differs from the first embodiment by an alternative design of the rotary latch 6' and the pawl 7', which will be discussed below.
- the first contact surface 17' of the rotary latch 6' is designed opposite the second contact surface 22'.
- the rotary latch 6' has a contact recess 31 which is designed adjacent to the first contact surface 17'.
- the second contact surface 22' forms at least one wall section of the contact recess 31, such as in particular the Figure 10 can be seen.
- the first blocking surface 15' is arranged facing away from the second blocking surface 21'.
- the first blocking surface 15' and the second blocking surface 21' are arranged in a direction away from the rotary latch 7', diverging from one another at the blocking surface angle 28. Furthermore, the first contact surface 17' and the second contact surface 22' are arranged diverging from one another in the direction of the locking pawl 7' at a contact surface angle 27 which is between 75° and 85°, the contact surface angle 27 being greater than the blocking surface angle 28.
- the first blocking surface 15' has a smaller length 19 than the second blocking surface 21', although this is not absolutely necessary, because the second blocking surface 21' only has to have a length with which it can at least partially be attached to the second contact surface 22'.
- the first blocking surface 15' can alternatively also have a greater length 19 than the second blocking surface 21'.
- the first contact surface 17' also has a greater length 29 than the second contact surface 22'.
- the contact recess 31 also has a contact contour 32 that is coordinated with the hook-shaped latch section 12. This coordination means that in the locking position, the first locking surface 15' rests at least partially on the first contact surface 17' and the second locking surface 21' rests at least partially on the second contact surface 22', so that a rotational movement of the rotary latch 6' is blocked both in the direction of the open position and in a direction opposite to the open position.
- the locking surface angle 28 is smaller than the contact surface angle 27, as in the first embodiment, as can be seen from the Figures 10 and 11 can be seen.
- the functioning of the second embodiment is identical and takes place according to the identical clamping principle, in that in the locking position the first locking surface 15' rests at least partially on the first contact surface 17' and the second locking surface 21' rests at least partially on the second contact surface 22', so that with regard to the principle according to the invention reference is made to the explanations for the first embodiment.
- the invention is directed to a lock arrangement 3 for a vehicle flap 2.
- the lock arrangement comprises the lock housing 4, the rotary latch 6 rotatably mounted on the lock housing 4 and the pawl 7 pivotably mounted on the lock housing 4.
- the pawl 7 has the mouth-shaped recess 25, which in the locking position at least partially receives the tooth-shaped projection 24 of the rotary latch 6 in such a way that both the first locking surface 15 at least partially on the first Contact surface 17 and the second blocking surface 21 at least partially rests on the second contact surface 22.

Der Erfindung liegt die Aufgabe zugrunde, auf konstruktiv einfache Weise und kostengünstig eine Schlossanordnung zu entwickeln, bei welcher eine unerwünschte Geräuschentwicklung vermieden wird und die sich durch eine kompakte Bauform auszeichnet.The invention is based on the object of developing a lock arrangement in a structurally simple and cost-effective manner, in which undesirable noise development is avoided and which is characterized by a compact design.
Bei einer Schlossanordnung der eingangs bezeichneten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, dass an einem Längsende der Sperrklinke ein hakenförmig ausgebildeter Klinkenabschnitt ausgebildet ist, der eine erste Sperrfläche aufweist, und dass die Drehfalle ein radial abstehendes Rastelement mit einer ersten Anlagefläche aufweist, wobei in Sperrstellung die Sperrklinke mit ihrem Klinkenabschnitt das Rastelement an der ersten Anlagefläche untergreift und die Sperrklinke mit der ersten Sperrfläche an der ersten Anlagefläche zumindest abschnittsweise derart anliegt, dass eine Drehbewegung der Drehfalle in Richtung der Offenstellung blockiert ist, wobei die Sperrklinke eine von der ersten Sperrfläche beabstandete zweite Sperrfläche aufweist, wobei die Drehfalle eine von der ersten Anlagefläche beabstandete zweite Anlagefläche aufweist, und wobei in Sperrstellung die Sperrklinke mit der zweiten Sperrfläche an der zweiten Anlagefläche zumindest abschnittsweise derart anliegt, dass eine Drehbewegung der Drehfalle in eine der Offenstellung entgegengesetzte Richtung blockiert ist, und wobei die erste Sperrfläche und die zweite Sperrfläche in einer von der Drehfalle wegweisenden Richtung unter einem Sperrflächen-Winkel auseinanderlaufend zueinander angeordnet sind. Die Sperrklinke blockiert somit eine Drehbewegung der Drehfalle sowohl in Drehrichtung ihrer Offenstellung als auch in eine der Offenstellung entgegengesetzte Drehrichtung. Folglich ist eine Drehbewegung der Drehfalle in beide Drehrichtungen allein durch die Sperrklinke blockiert.In a lock arrangement of the type described at the outset, this object is achieved according to the invention in that a hook-shaped pawl section is formed on one longitudinal end of the pawl, which has a first locking surface, and in that the rotary latch has a radially protruding locking element with a first contact surface, wherein in the locking position the pawl with its pawl section engages under the locking element on the first contact surface and the pawl with the first locking surface rests on the first contact surface at least in sections such that a rotary movement of the rotary latch in the direction of the open position is blocked, wherein the pawl has a second locking surface spaced from the first locking surface, wherein the rotary latch has a second contact surface spaced from the first contact surface, and wherein in the locking position the pawl with the second locking surface rests on the second contact surface at least in sections such that a rotary movement of the rotary latch in a direction opposite to the open position is blocked, and wherein the first locking surface and the second locking surface are in a direction pointing away from the rotary latch are arranged at a locking surface angle that diverges from one another. The pawl thus blocks rotation of the rotary latch both in the direction of rotation of its open position and in a direction opposite to the open position. Consequently, rotation of the rotary latch in both directions is blocked by the pawl alone.
Vorteilhafte und zweckmäßige Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous and expedient embodiments and further developments of the invention emerge from the subclaims.
Durch die Erfindung wird auf konstruktiv einfache Weise und kostengünstig eine Schlossanordnung bereitgestellt, welche sich durch einen einfachen sowie kompakten Aufbau auszeichnet und dennoch wirksam eine Drehbewegung der Drehfalle aus ihrer Raststellung heraus in beide Drehrichtungen verhindert, wenn die Sperrklinke in ihrer Sperrstellung angeordnet ist. Dadurch, dass die Sperrklinke eine Drehbewegung der Drehfalle in eine über die Raststellung hinausgehende Überhubstellung zu einem Zeitpunkt unterbindet, ab dem die Sperrklinke in ihrer Sperrstellung angeordnet ist, wird das aus dem Stand der Technik bekannte Problem des unerwünschten Klappergeräusches wirksam vermieden. Die Erfindung zeichnet sich durch eine rein mechanische Lösung aus, die im Unterschied zu bekannten Schlossanordnungen aus dem Stand der Technik ohne ein zusätzliches Bauteil, wie zum Beispiel ein hebelförmiges Ruhigstellungselement, und ohne etwaige gummiartige und verschleißanfällige Pufferelemente auskommt.The invention provides a lock arrangement in a structurally simple and cost-effective manner, which is characterized by a simple and compact design and yet effectively prevents a rotational movement of the rotary latch from its locking position in both directions of rotation when the pawl is arranged in its locking position. Because the pawl prevents a rotational movement of the rotary latch into an over-travel position beyond the locking position at a time when the pawl is arranged in its locking position, the problem of undesirable rattling noise known from the prior art is effectively avoided. The invention is characterized by a purely mechanical solution which, in contrast to known lock arrangements from the prior art, does not require an additional component, such as a lever-shaped immobilization element, and does not require any rubber-like and wear-prone buffer elements.
Gemäß einer ersten Ausführungsform der Erfindung ist es von besonderem Vorteil, wenn das Rastelement der Drehfalle als ein radial von der Drehfalle abstehender und zahnförmiger Ansatz ausgebildet ist und dass der Klinkenabschnitt der Sperrklinke eine maulförmige und auf den zahnförmigen Ansatz der Drehfalle abgestimmte Ausnehmung aufweist, wobei in Sperrstellung der zahnförmige Ansatz der Drehfalle zumindest abschnittsweise innerhalb der maulförmigen Ausnehmung der Sperrklinke liegend angeordnet ist. Der maulförmige Klinkenabschnitt der Sperrklinke und der zahnförmige Ansatz der Drehfalle gehen in Sperrstellung der Sperrklinke sowie in Raststellung der Drehfalle eine formschlüssige Verbindung ein, durch die sowohl eine Bewegung der Drehfalle in ihre Offenstellung als auch in eine der Offenstellung entgegengesetzte Richtung blockiert ist. Dabei ist die maulförmige Ausnehmung auf den zahnförmigen Ansatz derart abgestimmt, dass die Funktionsfähigkeit sowohl für die in Sperrstellung erwünschte Keilwirkung als auch für ein leichtes Lösen von Drehfalle und Sperrklinke bei Öffnung der Fahrzeugklappe gewährleistet ist.According to a first embodiment of the invention, it is particularly advantageous if the locking element of the rotary latch is designed as a tooth-shaped projection that protrudes radially from the rotary latch and that the pawl section of the locking pawl has a mouth-shaped recess that is matched to the tooth-shaped projection of the rotary latch, wherein in the locking position the tooth-shaped projection of the rotary latch is arranged at least partially within the mouth-shaped recess of the pawl. The mouth-shaped pawl section of the locking pawl and the tooth-shaped projection of the rotary latch form a positive connection in the locking position of the pawl and in the locking position of the rotary latch, by means of which the rotary latch can be moved both into its open position and into one of the The jaw-shaped recess is matched to the tooth-shaped projection in such a way that the functionality is guaranteed both for the wedge effect required in the locked position and for easy release of the rotary latch and pawl when the vehicle door is opened.
Konstruktiv besonders günstig ist es bei Ausgestaltung der ersten Ausführungsform, wenn die erste Anlagefläche und die zweite Anlagefläche der Drehfalle voneinander abgewandte Seitenflanken des zahnförmigen Ansatzes sind. Entsprechend sind die erste Sperrfläche und die zweite Sperrfläche einem Innenraum der maulförmigen Ausnehmung zugewandt ausgerichtet und einander gegenüberliegend sowie einander zugewandt angeordnet. Die Drehfalle sowie die Sperrklinke weisen somit eine konstruktiv einfache Form auf, die mit Hilfe bekannter Herstellungsverfahren kostengünstig hergestellt werden können.In terms of construction, it is particularly advantageous in the design of the first embodiment if the first contact surface and the second contact surface of the rotary latch are side flanks of the tooth-shaped projection facing away from one another. Accordingly, the first locking surface and the second locking surface are aligned facing an interior of the mouth-shaped recess and are arranged opposite one another and facing one another. The rotary latch and the locking pawl thus have a structurally simple shape that can be manufactured inexpensively using known manufacturing processes.
Der zahnförmige Ansatz und die maulförmige Ausnehmung sind derart aufeinander abgestimmt, dass in Sperrstellung zwischen dem zahnförmigen Ansatz und der maulförmigen Ausnehmung eine Keilverhakung auftritt. Dadurch verkeilen während der Fahrt eines Kraftfahrzeugs die Sperrklinke und die Drehfalle miteinander, wodurch Klappergeräusche verhindert werden. Hinsichtlich der Keilwirkung bzw. Keilverhakung ist es in Ausgestaltung für die erste Ausführungsform besonders günstig, wenn die erste Anlagefläche und die zweite Anlagefläche in Richtung der Sperrklinke unter einem Anlageflächen-Winkel zwischen 5° und 15° auseinanderlaufend zueinander angeordnet sind. Eine Ausgestaltung für eine zweite Ausführungsform sieht vor, dass die erste Anlagefläche der zweiten Anlagefläche gegenüberliegend ausgebildet ist, wobei die Drehfalle eine Anlageausnehmung aufweist, die an die erste Anlagefläche angrenzend angeordnet und ausgebildet ist, wobei die zweite Anlagefläche wenigstens einen Wandabschnitt der Anlageausnehmung bildet.The tooth-shaped projection and the mouth-shaped recess are coordinated with one another in such a way that a wedge-shaped interlock occurs between the tooth-shaped projection and the mouth-shaped recess in the locking position. As a result, the pawl and the rotary latch wedge together while a motor vehicle is driving, which prevents rattling noises. With regard to the wedge effect or wedge-shaped interlock, it is particularly advantageous in the design for the first embodiment if the first contact surface and the second contact surface are arranged in the direction of the pawl at a contact surface angle of between 5° and 15°, diverging from one another. A design for a second embodiment provides that the first contact surface is formed opposite the second contact surface, wherein the rotary latch has a contact recess which is arranged and formed adjacent to the first contact surface, wherein the second contact surface forms at least one wall section of the contact recess.
Für die zweite Ausführungsform ist in weiterer Ausgestaltung vorgesehen, dass die Anlageausnehmung eine mit dem hakenförmig ausgebildeten Klinkenabschnitt abgestimmte Anlagekontur aufweist, so dass in Sperrstellung zumindest abschnittsweise die erste Sperrfläche an der ersten Anlagefläche und zumindest abschnittsweise die zweite Sperrfläche an der zweiten Anlagefläche derart anliegen, dass eine Drehbewegung der Drehfalle in Richtung der Offenstellung und in eine der Offenstellung entgegengesetzte Richtung, also einer Überhubstellung, blockiert sind.For the second embodiment, it is further provided that the contact recess has a contact contour coordinated with the hook-shaped latch section, so that in the locking position, at least in sections, the first locking surface rests on the first contact surface and at least in sections, the second locking surface rests on the second contact surface in such a way that a rotational movement of the rotary latch in the direction of the open position and in a direction opposite to the open position, i.e. an overstroke position, is blocked.
In Bezug auf eine ausreichende Keilwirkung ist es in Ausgestaltung der zweiten Ausführungsform von Vorteil, wenn die erste Anlagefläche und die zweite Anlagefläche in Richtung der Sperrklinke unter einem Anlageflächen-Winkel zwischen 75° und 85° auseinanderlaufend zueinander angeordnet sind.With regard to a sufficient wedge effect, it is advantageous in the second embodiment if the first contact surface and the second contact surface are arranged diverging from one another in the direction of the pawl at a contact surface angle of between 75° and 85°.
Für die erste Ausführungsform und für die zweite Ausführungsform ist es im Hinblick auf die Funktionsfähigkeit (Keilwirkung, aber auch ein leichtes Lösen von Drehfalle und Sperrklinke bei Öffnung der Fahrzeugklappe) besonders günstig, wenn die erste Sperrfläche eine größere Länge als die zweite Sperrfläche aufweist. Dadurch ist gewährleistet, dass in Sperrstellung die Keilwirkung vorhanden ist und dass sich Drehfalle und Sperrklinke leicht lösen, wenn die Drehfalle in ihre Offenstellung gelangen soll. Ebenso günstig auf die Funktionssicherheit wirkt es sich in Ausgestaltung beider Ausführungsformen aus, wenn die erste Anlagefläche eine größere Länge als die zweite Anlagefläche aufweist.For the first embodiment and the second embodiment, it is particularly advantageous in terms of functionality (wedge effect, but also easy release of the rotary latch and pawl when the vehicle door is opened) if the first locking surface is longer than the second locking surface. This ensures that the wedge effect is present in the locked position and that the rotary latch and pawl are easily released when the rotary latch is to be moved into its open position. It also has a positive effect on functional reliability in both embodiments if the first contact surface is longer than the second contact surface.
Für beide Ausführungsformen ist es hinsichtlich der Funktionsfähigkeit ferner vorteilhaft, wenn die erste Anlagefläche und die zweite Anlagefläche in Richtung der Sperrklinke unter einem Anlageflächen-Winkel auseinanderlaufend zueinander angeordnet sind. Mit Bezug auf die Sperrklinke ist es ebenso von Vorteil, wenn die erste Sperrfläche und die zweite Sperrfläche in einer von der Drehfalle wegweisenden Richtung unter einem Sperrflächen-Winkel auseinanderlaufend zueinander angeordnet sind.For both embodiments, it is also advantageous in terms of functionality if the first contact surface and the second contact surface are arranged in the direction of the pawl at a contact surface angle that diverges from one another. With regard to the pawl, it is It is also advantageous if the first locking surface and the second locking surface are arranged in a direction away from the rotary latch, diverging from one another at a locking surface angle.
Damit in Sperrstellung eine ausreichende Reibung vorhanden ist, damit sich die Verkeilung von Sperrklinke und Drehfalle in der Sperrstellung nicht löst und dennoch für einen Öffnungsvorgang der Heckklappe ein Lösen der Verkeilung möglich ist, sieht eine Ausgestaltung vor, dass in Sperrstellung die erste Sperrfläche parallel zu der ersten Anlagefläche angeordnet ist, wobei die erste Sperrfläche und die zweite Sperrfläche in Richtung der Drehfalle auseinanderlaufend ausgestaltet sind. Ebenso ist es hierbei von Vorteil, wenn in Sperrstellung die erste Sperrfläche parallel zu der ersten Anlagefläche angeordnet ist, wobei der Abstand zwischen der ersten Sperrfläche und der zweiten Sperrfläche in Richtung der Drehfalle zunimmt.In order to ensure that there is sufficient friction in the locking position so that the wedging of the pawl and rotary latch does not come loose in the locking position and the wedging can still be released for the tailgate to be opened, one embodiment provides that in the locking position the first locking surface is arranged parallel to the first contact surface, with the first locking surface and the second locking surface being designed to diverge in the direction of the rotary latch. It is also advantageous if in the locking position the first locking surface is arranged parallel to the first contact surface, with the distance between the first locking surface and the second locking surface increasing in the direction of the rotary latch.
Gemäß einer alternativen Ausgestaltung ist es denkbar, dass die erste Sperrfläche nicht parallel zur ersten Anlagefläche gestaltet ist, sondern dass es sich bei zumindest einer der Flächen (Sperrfläche(n) und/oder Anlagefläche(n)) um im Radius gestaltete Flächen handelt, bei denen die Radien der Flächen (Sperrfläche(n) und/oder Anlagefläche(n)) zwar denselben Radius aufweisen, die Radienmittelpunkte aber versetzt zueinander liegend sind, so dass es nur zu einer Linienberührung von Sperrfläche und Anlagefläche kommt. Mit Hilfe einer solchen Ausgestaltung können die Reibungsverhältnisse zwischen Sperrfläche und Anlagefläche eingestellt werden. Der Versatz der Radienmittelpunkte bewirkt zudem, dass die Sperrklinke durch die Drehfalle, die in die Öffnungsstellung drängt, immer in die Sperrstellung gezogen wird.According to an alternative embodiment, it is conceivable that the first locking surface is not designed parallel to the first contact surface, but that at least one of the surfaces (locking surface(s) and/or contact surface(s)) is a surface designed in a radius, in which the radii of the surfaces (locking surface(s) and/or contact surface(s)) have the same radius, but the radius centers are offset from one another, so that there is only linear contact between the locking surface and the contact surface. With the help of such a configuration, the friction conditions between the locking surface and the contact surface can be adjusted. The offset of the radius centers also means that the locking pawl is always pulled into the locking position by the rotary latch, which pushes it into the open position.
Um die Drehfalle aus ihrer Raststellung in die Offenstellung zu drehen, ist in Ausgestaltung vorgesehen, dass die Drehfalle in Richtung ihrer Offenstellung federvorgespannt ist. Auf diese Weise kann auf einen motorischen Antrieb zur Bewegung der Drehfalle verzichtet werden.In order to rotate the rotary latch from its locking position to the open position, the rotary latch is spring-loaded in the direction of its open position. In this way, a motor drive to move the rotary latch is not necessary.
Schließleich sieht eine weitere Ausgestaltung vor, dass die Sperrklinke in Richtung ihrer Sperrstellung mit Hilfe eines Federelements federbeaufschlagt ist. Das Federelement drängt somit in Sperrstellung den hakenförmig ausgebildeten Klinkenabschnitt der Sperrklinke immer in Richtung der Drehfalle, so dass die Klemmwirkung zwischen dem Klinkenabschnitt der Sperrklinke und der Drehfalle durch das Federelement unterstützt wird. Dabei stützt sich ein Schenkel des Federelements an dem Schlossgehäuse ab, wohingegen der andere Schenkel des Federelements beispielsweise an einem Sperrklinkenansatz der Sperrklinke anliegt.Finally, a further embodiment provides that the pawl is spring-loaded in the direction of its locking position with the aid of a spring element. In the locking position, the spring element thus always pushes the hook-shaped pawl section of the pawl in the direction of the rotary latch, so that the clamping effect between the pawl section of the pawl and the rotary latch is supported by the spring element. One leg of the spring element is supported on the lock housing, whereas the other leg of the spring element rests, for example, on a pawl attachment of the pawl.
