The hatch lock has 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. The cinching system includes a force transfer arrangement for transferring a force exerted by the hatch drive arrangement to the hatch lock catch. The force transfer arrangement has a transfer element coupled to the hatch drive arrangement and a Bowden cable connecting the transfer element with the hatch lock catch. 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. ## Claims ### Claim 1 A hatch arrangement for a

The hatch arrangement according to claim 4, wherein 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. ### Claim 6 (depends on 4) The hatch arrangement according to claim 4, wherein the transfer element is movable between a first transfer element position and a second transfer element position. ### Claim 7 (depends on 6) The hatch arrangement according to claim 6, wherein a movement of the transfer element from the first transfer element position to the second transfer element position effects an increasement of a cutting angle defined between a first straight line that runs through the hatch axis and the lever axis and a second straight line that runs through the first coupling point and a connecting point in which the hatch drive arrangement is coupled to the vehicle body. ### Claim 8 (depends on 6) The hatch arrangement according to claim 6, 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 secondary latch position to the primary latch position. ### Claim 9 (depends on 8) The hatch arrangement according to claim 8, wherein an inner cable of the Bowden cable is coupled to the transfer element such that, during a movement of the transfer element from the first transfer element position to the second transfer element position, the inner cable of the Bowden cable is partially wound around the transfer element. ### Claim 10 (depends on 6) The hatch arrangement according to claim 6, wherein the first transfer element position and/or the second transfer element position are defined by a respective end stop. ### Claim 11 (depends on 6) The hatch arrangement according to claim 6, wherein, 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. ### Claim 12 (depends on 11) The hatch arrangement according to claim 11, wherein 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. ### Claim 13 (depends on 1) The hatch arrangement according to claim 1, wherein the hatch drive arrangement comprises a spindle drive. ### Claim 14 (depends on 1) The hatch arrangement according to claim 1, wherein the hatch arrangement comprises merely one single hatch drive arrangement with one single force transfer arrangement. ### Claim 15 (depends on 1) The hatch arrangement according to claim 1, wherein the hatch lock is arranged on the side of the hatch leaf which is opposite to the hatch axis. ### Claim 16 (depends on 1) The hatch arrangement according to claim 1, wherein the hatch drive arrangement is arranged in a wet area of the hatch arrangement, whereas the hatch lock is arranged in a dry area of the hatch arrangement. ### Claim 17 (depends on 1) The hatch arrangement according to claim 1, wherein the hatch drive arrangement comprises an element 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. ### Claim 18 (depends on 6) The hatch arrangement according to claim 6, wherein the hatch drive arrangement comprises at least one elastic member which forces the transfer element in the direction of the first transfer element position. ### Claim 19 (depends on 18) The hatch arrangement according to claim 18, wherein an elastic member is positioned such that it acts indirectly on the transfer element via the hatch lock catch and/or the Bowden cable, and/or an elastic member is positioned such that it acts directly on the transfer element. ### Claim 20 (depends on 1) The hatch arrangement according to claim 1, wherein an element for detecting a condition and/or a position of the hatch drive arrangement and/or a hard stop or damping stop is provided which dampens or limits or reverses a lateral movement of the hatch drive arrangement relative to the vehicle body, when the hatch drive arrangement moves the hatch leaf in the direction from the open hatch position to the closed hatch position. ### Claim 21 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

hatch leaf and being movable around a lever axis, 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, wherein a force applied on the hatch lock catch to move from the secondary latch position into the primary latch position is transferred from the hatch drive arrangement merely via the transfer element to the hatch leaf, and from the hatch leaf to the hatch lock catch, and wherein a movement of the transfer element from a first transfer element position to a second transfer element position, which effects the movement of the hatch lock catch from the secondary latch position into the primary latch position, effects an increasement of a cutting angle defined between a first straight line that runs through the hatch axis and the lever axis and a second straight line that runs through the first coupling point and a connecting point in which the hatch drive arrangement is coupled to the vehicle body. ### Claim 22 (depends on 1) A hatch drive arrangement for a hatch arrangement according to claim 1. ### Claim 23 A hatch arrangement for a motor vehicle, the hatch arrangement comprising
