Title: Hatch arrangement of a motor vehicle

Description:
FIELD OF THE TECHNOLOGY 
     The disclosure is directed at a hatch arrangement for a motor vehicle and a hatch drive arrangement. 
     BACKGROUND 
     Presently, the expression “hatch arrangement” is to be understood in a broad sense. It includes in particular any kind of doors of a motor vehicle such as side doors or back doors as well as tailgates, liftgates, trunk lids or engine hoods. 
     From the prior art and in particular U.S. Pat. No. 9,677,318 B2 a power tailgate with a cinching system is known. Once the catch of the hatch lock of the tailgate has reached its secondary latch position, the cinching system acts on the hatch lock to move the catch from the secondary latch position to the primary latch position, thereby ensuring an automatic closing of the hatch which is secure and complete. 
     In the prior art, a cinching system is built outside the hatch lock (external cinching system). According to said prior art the hatch arrangement comprises in one embodiment two hatch drive arrangements which both comprise a spindle drive. One end of the respective hatch drive arrangement is coupled to the vehicle body and the other end is coupled to a pivotable cinching catch of the cinching system. The cinching catch, which is arranged on the hatch leaf, is configured for engaging a cinching striker of the motor vehicle, which is arranged on the vehicle body. The respective hatch drive arrangement has two functions; on one hand the hatch drive arrangement is able to move the hatch leaf between an open hatch position and a closed hatch position and on the other hand the hatch drive arrangement also forms the drive for the cinching system when the hatch is almost closed. In the corresponding position of the hatch leaf at that time the hatch drive arrangement, in particular the spindle drive, causes a pivoting of the cinching catch towards a closed cinching catch position in which the cinching catch engages the cinching striker. By thus moving the cinching catch, the hatch leaf is also moved from the almost closed hatch position in the fully closed hatch position. Said movement of the hatch leaf in turn causes the hatch lock catch, which then is in contact with a corresponding hatch lock striker, to move from the secondary latch position in the primary latch position. 
     Although the hatch arrangement according to the prior art described above is very reliable, the construction of the hatch arrangement is quite complex, since on both sides of the hatch a respective hatch drive arrangement is needed to uniformly move the hatch leaf in the closed hatch position. 
     SUMMARY 
     It is therefore an object of the disclosure to improve the known hatch arrangement including a cinch system to make it more simple and more robust in its construction and to overcome the aforementioned drawbacks. 
     The above noted object is solved for a hatch arrangement for a motor vehicle according to the disclosure. 
     For a hatch drive arrangement for such a hatch arrangement the above noted object is solved with the features disclosed herein. 
     The basic idea underlying the disclosure is to provide a force transfer arrangement for transferring a pulling force exerted by the hatch drive arrangement to the hatch lock catch for moving the hatch lock catch from its secondary latch position to its primary latch position. Also in this case the hatch drive arrangement has two functions, that is, on one hand it is used for moving the hatch leaf between the open hatch position and the closed hatch position, and on the other hand it is used for operating the cinching system. However, according to the disclosure the hatch drive arrangement does not actuate a separate cinching catch which moves the hatch leaf from an almost closed hatch position in a fully closed hatch position which in turn moves the separate hatch lock catch from the secondary latch position in the primary latch position, but the hatch drive arrangement exerts its pulling force via a transfer element and a Bowden cable to the hatch lock catch itself. Accordingly, the hatch lock catch is moved, namely pulled, from the secondary latch position in the primary latch position directly by the cinching system. According to the disclosure there is no need for two separate hatch drive arrangements and cinching systems with separate cinching catches and cinching strikers arranged on both sides of the hatch leaf. Moreover, no sensors are required in the hatch lock sensing the secondary latch position and the primary latch position for controlling the hatch drive arrangements. In the present case the internal sensors of the hatch drive arrangement, in particular of the spindle drive, may be used to start and stop the driving motion. Accordingly, the construction of the cinching system is more simple and more robust compared to the prior art. Also, since the cinching system directly acts on the hatch lock catch, which is usually arranged substantially in the middle of the outer most hatch leaf edge, there is no longer the need to uniformly operate separate cinching catches at both lateral sides of the hatch leaf. 
     In detail, according to the present disclosure the hatch arrangement comprises as part of the cinching system a force transfer arrangement for transferring a pulling force exerted by the hatch drive arrangement to the hatch lock catch, the force transfer arrangement comprising a transfer element coupled to the hatch drive arrangement and a Bowden cable connecting the transfer element with the hatch lock catch, wherein in the closed hatch position of the hatch leaf the hatch arrangement is free from pulling forces between the transfer element and the vehicle body. 
     Various embodiments further specify the functioning of the transfer element of the force transfer arrangement. In particular, the transfer element merely has the purpose of transferring forces between the hatch drive arrangement and the hatch leaf on one hand and between the hatch drive arrangement and the hatch lock catch on the other hand. Beside that, the transfer element does not need to absorb further loads. Particularly, the transfer element is not used to pull the hatch leaf towards the vehicle body to move the hatch leaf from the named almost closed hatch position into the fully closed hatch position. Instead, according to the present disclosure this is done by the hatch lock catch when engaging the hatch lock striker and when being pulled from the secondary latch position into the primary latch position by the cinching system. 
     According to various embodiments the transfer element is a lever. With such a lever a force, in particular a pulling force, exerted by the hatch drive arrangement may be easily transferred to the Bowden cable connected with the hatch lock catch, while the force, in particular the pulling force, exerted by the hatch drive arrangement may also be transferred to the hatch leaf via the lever axis to move the hatch leaf between the open hatch position and the almost closed and the fully closed hatch position. However, it is also conceivable to provide a transfer element which transfers the respective forces and movements linearly. However, as described before, it is an option to transfer the linear movement of the hatch drive arrangement into a pivoting movement of the transfer element, which pivoting movement is then transferred into a linear movement of the Bowden cable. 
     Various embodiments define motion courses of the transfer element, in particular the lever. 
     As specified in various embodiments, a spindle drive—which is an advantageous drive solution for a hatch drive arrangement—is provided for both the movement of the hatch leaf and the operation of the cinching system. The construction of a spindle drive is for example described in U.S. Pat. No. 9,255,436 which is hereby incorporated by reference. However, it is also conceivable to use a pushrod drive instead. A pushrod drive construction is for example described in U.S. Pat. No. 9,103,154 which is also hereby incorporated by reference. 
     According to various embodiments, only one single hatch drive arrangement and in particular only one single spindle drive is provided for the above mentioned purposes, that is for moving both the hatch leaf an the hatch lock catch. As already described before, it is no longer necessary to provide two separate hatch drive arrangements and cinching systems, since it is now possible, to transfer the pulling forces from the hatch drive arrangement via the transfer element and the Bowden cable directly to the hatch lock catch, which is usually arranged in the middle section of the outer most hatch leaf edge, which is the edge or side of the hatch leaf opposite to the hatch axis. 
     Various embodiments make use of the fact that a Bowden cable can easily penetrate through a separating wall which separates the wet area of the hatch arrangement from the dry area of the hatch arrangement. Since a Bowden cable comprises a movable inner cable and a stationary housing, the hole in the separating wall through which the Bowden cable housing extends can be easily sealed. 
     According some embodiments, the hatch drive arrangement comprises means for detecting a condition and/or a position of the hatch drive arrangement which corresponds to the condition of the hatch lock when the hatch lock catch is in the secondary latch position. For example, a pushbutton may be arranged on a housing section of the hatch arrangement, in particular a housing section of the spindle drive, which pushbutton is actuated in a specific position of said housing section relative to the vehicle body, for example, when the housing section presses the pushbutton against the vehicle body. At the same time when the pushbutton is actuated, the hatch lock catch is moved in the second latch position. In said condition of the hatch lock the actuation of the pushbutton may cause the hatch drive arrangement, in particular the spindle drive, to exert a higher pulling force than before, such that a higher pulling force is applied to the hatch lock catch while moving from the secondary latch position to the primary latch position. It is also conceivable to use a Hall-effect sensor, which for example counts the revolutions of the drive shaft of the hatch drive arrangement motor, in particular the motor of the spindle drive. By counting the revolutions, the condition of the hatch drive arrangement may also be detected which corresponds to the condition of the hatch lock when the hatch lock catch is moved in the secondary latch position. 
     An embodiment provides a hatch arrangement for a motor vehicle, the hatch arrangement comprising a hatch leaf pivotably coupled to a vehicle body of the motor vehicle and being movable around a hatch axis between an open hatch position and a closed hatch position, a hatch drive arrangement for moving the hatch leaf, a hatch lock arranged on the hatch leaf, the hatch lock comprising a hatch lock catch for engaging a hatch lock striker in a retaining manner in a primary latch position and in a secondary latch position and for disengaging the hatch lock striker in an open latch position, and a cinching system configured to move the hatch lock catch from the secondary latch position to the primary latch position, wherein the hatch arrangement comprises, as part of the cinching system, a force transfer arrangement for transferring a pulling force exerted by the hatch drive arrangement to the hatch lock catch, the force transfer arrangement comprising a transfer element coupled to the hatch drive arrangement and a Bowden cable connecting the transfer element with the hatch lock catch, wherein in the closed hatch position of the hatch leaf the hatch arrangement is free from pulling forces between the transfer element and the vehicle body. 
     In various embodiments, the transfer element itself does not provide a locking function between the hatch leaf and the vehicle body. 
     In various embodiments, during most of the movement or the whole movement of the hatch lock catch from the second latch position to the primary latch position no forces are transferred from the transfer element to the vehicle body. 
     In various embodiments, the transfer element is a lever mounted to the hatch leaf and being pivotable around a lever axis, wherein the hatch drive arrangement is coupled to the transfer element at a first coupling point and the Bowden cable is coupled to the transfer element at a second coupling point, the first coupling point and the second coupling point being offset from the lever axis of the transfer element, wherein the lever is mounted at a lateral side of the hatch leaf and/or wherein the lever axis is substantially parallel to the hatch axis. 
     In various embodiments, the transfer element comprises one effective lever arm, wherein both the first coupling point and the second coupling point are arranged on the same effective lever arm. 
     In various embodiments, the transfer element is movable between a first transfer element position and a second transfer element position, wherein a movement of the transfer element from the first transfer element position to the second transfer element position effects the movement of the hatch lock catch from the second latch position to the first latch position. 
     In various embodiments, the first transfer element position and/or the second transfer element position are defined by a respective end stop, wherein the respective end stop is formed on the hatch leaf. 
     In various embodiments, when the transfer element is in the first transfer element position, the first coupling point is positioned at one side of an imaginary line which extends through the first coupling point and a connecting point in which the hatch drive arrangement is coupled to the vehicle body, wherein the side of the imaginary line is the side facing in a direction from the vehicle body towards the hatch leaf. 
     In various embodiments, during the whole movement of the transfer element from the first transfer element position to the second transfer element position the first coupling point does not cross the imaginary line extending through the first coupling point and the connecting point in which the hatch drive arrangement is coupled to the vehicle body. 
     In various embodiments, the hatch drive arrangement comprises a spindle drive. 
     In various embodiments, the hatch arrangement comprises merely one single hatch drive arrangement with one single force transfer arrangement, wherein the hatch arrangement comprises merely one single spindle drive. 
     In various embodiments, the hatch lock is arranged on the side of the hatch leaf which is opposite to the hatch axis. 
     In various embodiments, the hatch drive arrangement is arranged in the wet area of the hatch arrangement, whereas the hatch lock is arranged in the dry area of the hatch arrangement, wherein also the transfer element is arranged in the wet area of the hatch arrangement, wherein the Bowden cable extends from the wet area to the dry area through a seal in a separating wall which separates the wet area from the dry area. 
     In various embodiments, the hatch drive arrangement comprises means for detecting a condition and/or a position of the hatch drive arrangement which corresponds to the condition of the hatch lock when the hatch lock catch is in the secondary latch position, wherein the means include an electronic or mechanical pushbutton and/or a Hall-effect sensor. 
     In various embodiments, a hatch drive arrangement for a hatch arrangement as described herein is provided.

     DETAILED DESCRIPTION 
     The hatch arrangement shown in the figures is assigned to a motor vehicle  1  shown partially in  FIG. 1 . The hatch arrangement comprises a hatch leaf  2 —in the embodiment shown the hatch leaf  2  is a tailgate  2   a —pivotably coupled to a vehicle body  3  of the motor vehicle  1  and being movable between an open hatch position ( FIG. 1 ,  FIG. 2 a   ) and a closed hatch position, in particular an almost closed hatch position ( FIG. 2 b   ,  FIG. 3 a   ) and a fully closed hatch position ( FIG. 3 b   ). The hatch arrangement may also comprise any other kind of door of a motor vehicle, such as a sliding door. The hatch arrangement further comprises a hatch drive arrangement  4  for moving the hatch leaf  2 . In particular, the hatch drive arrangement  4  may be configured for moving the hatch leaf  2  between the open hatch position and the respective closed hatch position in one or both directions. 
     Furthermore, a hatch lock  5  is arranged on the hatch leaf  2 , the hatch lock  5  comprising a hatch lock catch  6  for engaging a hatch lock striker  7  in a retaining manner in a secondary latch position and in a primary latch position and for disengaging the hatch lock striker  7  in an open latch position. The hatch lock catch  6  being in the secondary latch position is shown in  FIG. 2 b    and  FIG. 3 a   . The hatch lock catch  6  being in the primary latch position is shown in  FIG. 3 b   . The open latch position of the hatch lock catch  6  is shown in  FIG. 1  and  FIG. 2 a   . It can be seen that when the hatch leaf  2  is in the open hatch position, the hatch lock catch  6  is in the open latch position. When the hatch leaf  2  has been moved from the open hatch position to the almost closed hatch position shown in  FIG. 2 b   , the hatch lock catch  6  is in the secondary latch position. When having moved the hatch leaf  2  further into the fully closed hatch position, as shown in  FIG. 3 b   , the hatch lock catch  6  is in the primary latch position. 
     As described above, the movements of the hatch leaf  2  are caused by the hatch drive arrangement  4 . The movement of the hatch lock catch  6  from the secondary latch position in the primary latch position is caused by a cinching system  8 . 
     The proposed hatch arrangement is characterized in that it comprises, as part of the cinching system  8 , a force transfer arrangement  9  for transferring a pulling force exerted by the hatch drive arrangement  4  to the hatch lock catch  6 . The force transfer arrangement  9  comprises a transfer element  10  coupled to the hatch drive arrangement  4  and a Bowden cable  11  connecting the transfer element  10  with the hatch lock catch  6 , thereby coupling the hatch drive arrangement  4  to the hatch lock catch  6 . The hatch drive arrangement  4  therefore does not only move the hatch leaf  2  between the respective hatch positions, but also causes the movement of the hatch lock catch  6  from the secondary latch position in the primary latch position in a cinching action. Accordingly, the cinching system  8  directly acts on the hatch lock catch  6  (internal cinching system). 
     As can be seen in the figures, in the closed hatch position of the hatch leaf  2 , in particular in the almost closed hatch position as shown in  FIG. 2 b    and  FIG. 3 a    and/or in the fully closed hatch position as shown in  FIG. 3 b   , the hatch arrangement is free from pulling forces between the transfer element  10  and the vehicle body  3 . In particular, the only pulling forces holding the hatch leaf  2  in its respective closed hatch position are pulling forces between the hatch lock catch  6  and the hatch lock striker  7 . Accordingly, in the hatch arrangement, in some embodiments, only the hatch lock catch  6  provides a locking function between the hatch leaf  2  and the vehicle body  3 . In contrast to the prior art, the transfer element  10  itself, in some embodiments, does not provide a locking function between the hatch leaf  2  and the vehicle body  3 . 
     In particular, at least during most of the movement of the hatch lock catch  6  from the secondary latch position to the primary latch position, such as during the whole movement of the hatch lock catch  6  from the secondary latch position to the primary latch position, no forces at all are transferred from the transfer element  10  to the vehicle body  3 . 
     In the particular embodiment shown in the figures, the transfer element  10  is formed as a lever  10   a  which is mounted to the hatch leaf  2 . Said lever  10   a  is pivotable around a lever axis x 2 . However, for transferring the forces from the hatch drive arrangement  4  to both the hatch leaf  2  and the hatch lock catch  6  it is also conceivable to use a linearly movable transfer element as well. 
     In the present case the hatch drive arrangement  4  is coupled to the transfer element  10 , here to the lever  10   a , at a first coupling point  12 . The Bowden cable  11  is coupled to the same transfer element  10  at a second coupling point  13 . The first coupling point  12  and the second coupling point  13  are offset from the lever axis x 2 . In the present case the lever  10   a  is mounted at a lateral side of the hatch leaf  2 , that is the lateral edge of the hatch leaf  2  extending substantially perpendicular to the hatch axis x 1 . Here, the lever axis x 2  is substantially parallel to the hatch axis x 1 . 
     With the above described construction of the exemplary embodiment, a linear movement of the hatch drive arrangement  4  is transferred into a pivoting movement of the transfer element  10 , which pivoting movement is transferred into a further linear movement of the Bowden cable  11 . A linear movement of the Bowden cable  11  means that an inner cable of the Bowden cable  11  moves back and forth inside the Bowden cable housing formed around said inner cable. The Bowden cable housing itself is fixed and therefor can not move back and forth. 
     Accordingly, in the proposed hatch arrangement shown in the exemplary embodiment of the figures the hatch drive arrangement  4  and the Bowden cable  11  both linearly transfer forces, whereas the lever  10   a  transfers forces by pivoting. Here, the only torque exerted on the lever  10   a  is a torque exerted by the hatch drive arrangement  4  and the Bowden cable  11 . 
     As best can be seen in  FIGS. 3 a  and  b   , the transfer element  10  comprises an effective lever arm  14 , here in particular exactly one effective lever arm  14 , wherein both the first coupling point  12  and the second coupling point  13  are arranged on the same effective lever arm  14 . The transfer element  10 , here the lever  10   a , is movable between a first transfer element position ( FIG. 3 a   ) and a second transfer element position ( FIG. 3 b   ), wherein a movement of the transfer element  10  from the first transfer element position to the second transfer element position effects the movement of the hatch lock catch  6  from the secondary latch position in the primary latch position. 
     The hatch drive arrangement  4 , the force transfer arrangement  9  and/or the hatch leaf  2  are arranged and configured such that a movement of the transfer element  10  from the first transfer element position to the second transfer element position is only effected after the hatch leaf  2  has been moved from the open hatch position to the almost closed hatch position, the latter shown in  FIG. 3 a   . In contrast thereto, when the hatch leaf  2  is in an open hatch position, the hatch drive arrangement  4  is only able to move the hatch leaf  2  into the almost closed hatch position shown in  FIG. 2 b    and  FIG. 3 a   . During the movement of the hatch leaf  2  from the open hatch position to the almost closed hatch position, the transfer element  10 , here the lever  10   a , does not move, but remains in its first transfer element position. To hold the transfer element  10  in the first transfer element position during movement of the hatch leaf  2  from the open hatch position to the almost closed hatch position, also an elastic member  22 , e.g. a spring, may be provided which forces the transfer element  10  in the direction of the first transfer element position. In this case the elastic member  22  is a spring, such as a rotational spring, acting on the hatch lock catch  6  such that the hatch lock catch  6  is forced towards the open latch position. As soon as the hatch leaf  2  reaches, during its closing movement, the almost closed hatch position of  FIG. 3 a   , the pulling force exerted by the hatch drive arrangement  4  to the transfer element  10  is increased such that the transfer element  10  is pulled from its first transfer element position to its second transfer element position. This in turn causes the respective movement of the Bowden cable  11  and accordingly of the hatch lock catch  6  from the secondary latch position into the primary latch position, thereby forcing the hatch leaf  2  from the almost closed hatch position of  FIG. 3 a    into the fully closed hatch position of  FIG. 3   b.    
     In the shown embodiment, the first transfer element position and the second transfer element position are both defined by a respective end stop  15 ,  16 , both end stops  15 ,  16  being formed on the hatch leaf  2 , in particular on the lateral side or edge of the hatch leaf  2 . The end stops  15 ,  16  are arranged such that, when the transfer element  10 , here the lever  10   a , is in the first transfer element position, the first coupling point  12  is positioned at one side of an imaginary line L which extends through the first coupling point  12  and a connecting point  17  in which the hatch drive arrangement  4  is coupled to the vehicle body  3  and which is in particular offset from the hatch axis x 1 . In some embodiments, the named side of the imaginary line L is the side facing in a direction X from the vehicle body  3  towards the hatch leaf  2 . 
     The imaginary line L defines a dead point for the first coupling point  12 . If the lever  10   a  would be pivoted into a position where the first coupling point  12  is positioned on the imaginary line L—said position being the dead point—, no torque would be transferred from the hatch drive arrangement  4  to the transfer element  10  and the transfer element  10  would not move. To avoid this, in the exemplary embodiment shown in the figures during the whole movement of the transfer element  10  from the first transfer element position to the second transfer element position the first coupling point  12  does not cross the imaginary line L. In the contrary, as can be seen from  FIGS. 3 a  and  b   , due to the end stops  15 ,  16 , in particular the end stop  15  defining the first transfer element position, the first coupling point  12  has a motion path which is completely on the side of the imaginary line L facing in the direction X. Therefore, the first coupling point  12  can not be positioned in the dead point on the imaginary line L or even on the opposite side of the imaginary line L. However, it is also conceivable to provide a construction where the first coupling point  12  would be arranged in the dead point or even on the opposite side of the imaginary line L, when the transfer element  10  is in its first transfer element position. Such a construction however requires means that push the transfer element  10  towards the side of the imaginary line L facing in the direction X, when the hatch leaf  2  reaches the almost closed hatch position shown in  FIG. 3 a    during its closing movement. Such a means could for example be a protrusion arranged on the vehicle body  3  facing in the direction X. Accordingly, when the hatch leaf  2  reaches the almost closed hatch position, the means or protrusion, respectively, moves the transfer element  10  from its first transfer element position into a position where the first coupling point  12  is on the respective other side of the imaginary line L. 
     It can be that the hatch drive arrangement  4  comprises a spindle drive  18 . The hatch drive arrangement  4  may also comprise any other kind of type of drive, in particular linear drive, for example a pushrod drive. A movement of the respective drive, in particular spindle drive  18 , is then transferred via the transfer element  10  and the Bowden cable  11  to the hatch lock catch  6  as well as to the hatch leaf  2 . 
     It can also be that the hatch lock  5  is arranged on the side or edge of the hatch leaf  2  which is opposite to the hatch axis x 1 , that is the side facing away from the hatch axis x 1 . The hatch lock  5  can thereby be arranged substantially in the middle of the respective side of the hatch leaf  2  such that, when the hatch lock catch  6  is moved from the secondary latch position to the primary latch position, the hatch leaf  2  is uniformly moved from the almost closed hatch position of  FIG. 3 a    in the fully closed hatch position in  FIG. 3   b.    
     Since the cinching system  8  can only use one single catch, namely the hatch lock catch  6 , merely one single hatch drive arrangement  4  with one single force transfer arrangement  9  of the type describe before and such as merely one single spindle drive  18  is needed to apply the required forces to the hatch leaf  2  and to the hatch lock catch  6 . In some embodiments, the hatch drive arrangement  4  and/or the spindle drive  18  is placed e. g. in a rainwater gutter associated with the hatch leaf  2 . 
     It can be that the hatch drive arrangement  4  is arranged in the wet area of the hatch arrangement, whereas the hatch lock  5  is arranged in the dry area of the hatch arrangement. In some embodiments, also the transfer element  10  is arranged in the wet area of the hatch arrangement, wherein the Bowden cable  11  extends from the wet area to the dry area through a seal in a separating wall (not shown) which separates the wet area from the dry area. 
     The hatch lock  5  arranged on the hatch leaf  2  is shown in  FIGS. 2 a  and  b    and  FIGS. 3 a  and  b    together with the hatch leaf  2  being in an associated hatch position. According to this embodiment, the hatch lock  5  not only comprises the hatch lock catch  6  for engaging the hatch lock striker  7  as described before, but also comprises a pawl  19  for a blocking engagement with the hatch lock catch  6  and a release actuation lever (not shown) for deflecting the pawl  19  as well as other components of a vehicle lock. Moreover, in the exemplary embodiment shown in the figures the hatch lock catch  6  comprises means  21  for movably attaching the Bowden cable  11  such that the Bowden cable  11 , in particular the inner cable, is always on tension and does not sag in particular when the hatch lock catch  6  is moved from the open latch position to the secondary latch position. Here for example a slotted hole is provided in the hatch lock catch  6 , in which the respective end of the Bowden cable  11  is movably guided. 
     It can be that the hatch drive arrangement  4  comprises means for detecting a condition and/or a position of the hatch drive arrangement  4 . In the present embodiment, an electronic pushbutton  20  is arranged on the housing of the hatch drive arrangement  4 , in particular on the housing of the spindle drive  18 . While the hatch drive arrangement  4  moves the hatch leaf  2  from the open hatch position to the almost closed hatch position, in the almost closed hatch position the pushbutton  20  comes into contact with the vehicle body  3  ( FIG. 2 b   ). At the same time, what also can be seen in  FIG. 2 b   , the hatch lock striker  7  has pushed the hatch lock catch  6  into the secondary latch position. Accordingly, the means or pushbutton  20 , respectively, is suitable to detect a condition and/or position of the hatch drive arrangement  4  which corresponds to the condition of the hatch lock  5  when the hatch lock catch  6  is in the secondary latch position. Actuation of the pushbutton  20  may then generate a signal that causes the hatch drive arrangement  4  or spindle drive  18 , respectively, to exert a larger pulling force for the purpose of moving the hatch lock catch  6  from the secondary latch position in the primary latch position. It is also conceivable to e. g. use a Hall-effect sensor, in particular a Hall-effect sensor of the spindle drive  18 , for the same purpose. The Hall-effect sensor in particular is an incremental sensor and counts the revolutions of the drive shaft of the hatch drive arrangement  4  or spindle drive  18 , respectively. Since a specific number of revolutions can be associated with a specific latch position, also by means of a Hall-effect sensor the exerted pulling force of the hatch drive arrangement  4  may be increased as soon as the hatch lock catch  6  is in its secondary latch position. 
     Further, a hatch drive arrangement  4  for a hatch arrangement according to the proposal and any of its embodiments is disclosed.
