    A part of the car, and a detection device for detecting movement between the device and the detection device.
    US20030038606 discloses an electromechanical clamp protection for, for example, a side window in a vehicle. According to this device, the load on the motor that controls the closing of the window is monitored and if something gets stuck, the device will switch off the motor so that the object can be removed.
    WO2011003816 shows a clamp protection for e.g. a sunroof. A limit value is set for how large the force may be on the part to be closed. Exceeding that value indicates that something is wrong.
    DE102009020340 describes a clamp protection that prevents the fingers from getting caught.
    The clamp protection consists of i.a. of a cylinder comprising a rod which is axially movable relative to the cylinder. The spring function is arranged in the cylinder. The technology is used for areas other than sunroofs.
    The object of the present invention is to provide an opening device for a sunroof which has a simple, safe and robust function and which has a relatively low manufacturing cost.
    Summary of the invention The above objects are achieved according to the invention defined by the independent claim.
    Preferred embodiments are defined by the dependent claims.
    The object is thus achieved according to the invention with a device for opening and closing a sunroof on a vehicle where the device is adapted to actuate the sunroof in a substantially vertical direction, wherein the device comprises an opening means adapted to open and close the sunroof and the opening means comprises a first actuating part and a second activation part. Furthermore, a drive unit is provided which is adapted to generate rotational movements in a first (A) and a second (B) direction, and a coupling unit is arranged between said opening means and said drive unit and adapted to transmit rotational movements from the drive unit to the opening means. The coupling unit comprises a first coupling part and a second coupling part, the drive unit being adapted to rotate said first coupling part which is adapted to transmit the rotation to the second coupling part when the gravity of the sunroof, via the opening means, acts on the second coupling part with a substantially vertical downward force exceeding a predetermined threshold value. The coupling unit is adapted to be either in a coupled state when the second coupling part cooperates with the first coupling part so that the rotation generated by the drive unit is transmitted to said opening means for opening or closing the sunroof, or in an uncoupled state when the second coupling part does not cooperate with the first coupling part and the rotation are not transmitted to said opening means, the uncoupled state being present when said substantially vertically downward force is below said predetermined threshold value.
    According to one embodiment, the first actuating part is a drive shaft in the form of a tube with a circular cross-section and which is provided with threads on at least a part of the outside, and that the second actuating part is a running sleeve in the form of a tube with a circular cross-section and is provided with threads on the inside, where the threads on the outside of the drive shaft can cooperate with the threads on the inside of the race sleeve. The running sleeve is adapted to be mounted in the sunroof and adapted to cooperate with the drive shaft in such a way that when the drive shaft rotates in the first direction (A) the sunroof opens and when the drive shaft rotates in the second direction (B) the sunroof closes.
    With a mechanical clamp protection, according to the invention, with relatively few parts, the function can be fulfilled with a simpler and cheaper control unit or even without a control unit at all as it is not dependent on electronics at all. It also includes a locking function that pulls the sunroof the last millimeters and creates a compression on the seals.
    The invention thus relates to a mechanical clamp protection for the tilting in electric sunroofs and thus removes the need for sensors and / or control units for this function. Brief Description of the Drawings Figure 1 shows a schematic cross-section of a sunroof where the device according to the present invention is arranged.
    Figures 2-4 show a cross section of the device according to the present invention in different states.
    Figures 5-7 schematically illustrate different embodiments of the coupling unit according to the present invention.
    Detailed Description of Preferred Embodiments of the Invention The invention will now be described in detail with reference to the accompanying figures.
    Figure 1 shows a schematic cross-section of a sunroof 4, preferably placed on a vehicle, provided with a device 2 for opening and closing the sunroof 4 where the device 2 is adapted to actuate the sunroof 4 in a substantially vertical direction. The device 2 comprises an opening means 6 which is adapted to open and close the sunroof 4 and where the opening means 6 comprises a first activating part 8 and a second activating part 10.
    The device further comprises a drive unit 12 which is adapted to generate rotational movements in a first (A) and a second (B) direction, and a coupling unit 14, arranged between said opening means 6 and said drive unit 12 and which is adapted to transmit rotational movements from the drive unit 12. to the opening means 6.
    The coupling unit 14 comprises a first coupling part 16 and a second coupling part 18, the drive unit 12 being adapted to rotate said first coupling part 16 which is adapted to transmit the rotation to said second coupling part 18 when the gravity of the sunroof, via said opening means 6, affects said second coupling part 18 with a substantially vertical downward force exceeding a predetermined threshold value.
    The coupling unit 14 is adapted to be either in a coupled state when the second coupling part 18 cooperates with the first coupling part 16 so that the rotation, in the direction A or B and generated by the drive unit 12, is transmitted to said opening means 6 for opening or closing the sunroof. The coupling unit 14 is further adapted to be in an uncoupled state when the second coupling part 18 does not co-operate with the first coupling part 16 and the rotation is thus not transmitted to the opening member 6, the uncoupled state being present when it is substantially vertically downwardly directed. the force is below said predetermined threshold value. The uncoupled condition occurs, for example, if an object prevents the sunroof from closing, which means that the downward force is reduced, and squeezing can be avoided if the object is, for example, a hand or a finger.
    The drive unit 12 is adapted to receive control signals 20 including instructions to open or close the sunroof 4 by generating the rotational movements in the first (A) and the second (B) direction, respectively. These control signals can, for example, be generated via controls in connection with the instrument panel.
    According to one embodiment, said first actuating part 8 is a drive shaft in the form of a tube with a circular cross-section and which is provided with threads 22 on at least a part of the outside.
    The second actuating part 10 is then a running sleeve in the form of a tube with a circular cross-section and provided with threads 24 on the inside. The threads 22 on the outside of the drive shaft are adapted to cooperate with the threads on the inside of the race sleeve.
    The running sleeve is adapted to be mounted in the sunroof 4 and is thus adapted to cooperate with the drive shaft in such a way that when the drive shaft rotates in the first direction (A) the sunroof opens and when the drive shaft rotates in the second direction (B) the sunroof closes. These directions of rotation are shown in Figure 2.
    The running sleeve 10 is preferably mounted in the rear edge of the sunroof and has a downward force due to the weight of the sunroof. The drive shaft 8 is threaded in the running sleeve 10 and, according to one embodiment, the second coupling part 18 is located in the lower edge of the drive shaft 8. A locking shaft 11 runs through the drive shaft 8 and runs freely inside the drive shaft 8.
    At the lower end of the locking shaft 11 is the drive unit 12 which can for instance consist of an electric motor, a drive gear which is driven by the electric motor with a screw wheel and which thereby forms a worm gear. In the lower part of the locking shaft 11 is the first coupling part 16, which can for instance consist of a spring-loaded tooth coupling. Figures 2-4 schematically illustrate a resilient unit 13 arranged below the first coupling part 16 and which can for instance consist of a coil spring or a resilient rubber cylinder. The first coupling part 16 is mounted on, and always rotates with, the locking shaft 11 but preferably has a small play linear with the reading shaft 11.
    The embodiments with the spring-loaded toothed coupling are illustrated in Figure 5 and will be described in more detail below.
    When the sunroof is opened, the drive unit drives the read shaft 11 in the first direction of rotation A and the coupling unit 14 is in its coupled state and the drive shaft 8 drives the impeller 10 and then the sunroof upwards.
    When closed, the motor drives the locking shaft 11 in the second direction of rotation B and the coupling unit 14 in its coupled state, and the drive shaft 8 in turn drives the running sleeve 10 and the sunroof downwards.
    If an object ends up between the sunroof and the roof, the downward force on the running sleeve 10 is released (since it is connected to the sunroof) and the coupling unit 14 releases the drive on the drive shaft 8, whereupon the sunroof stops being driven downwards. However, the motor still runs and drives the read shaft 11 as long as it is activated.
    Figures 5-7 schematically illustrate different embodiments of the coupling unit according to the present invention. For all these embodiments, if the downward force acting on the coupling unit exceeds a threshold value, the coupling unit must transmit the rotation to the opening member 6. The size of this threshold value depends, among other things, on the weight of the sunroof. The threshold value must be high enough to ensure normal operation of the device, ie. that opening and closing of the sunroof can take place without disturbance.
    According to an embodiment illustrated by the schematic view in Figure 5, said first and second coupling parts 16, 18 are provided with cooperating teeth 26 for transmitting the rotation from the first coupling part 16 to the second coupling part 18. The teeth can of course be formed on very different ways. The figure shows a tooth 10 which is designed so that if the drive unit 12 rotates the first coupling part 16 in the direction of rotation B, i.e. the sunroof is closing, the clutch will slip, and finally disengage, as the teeth slide off each other as the downward force decreases.
    According to another embodiment, illustrated by the schematic view in Figure 6, said first and second coupling parts 16, 18 are provided with friction material 28 for transmitting the rotation from the first coupling part 16 to the second coupling part 18. The friction material may for instance be roughened metal surfaces or blasted surfaces.
    According to another embodiment, illustrated by the schematic picture in Figure 6, said first and second coupling parts 16, 18 are provided with a magnetic material 30 for transmitting the rotation from the first coupling part 16 to the second coupling part 18. The magnetic material is arranged on the coupling parts 16, 18 by giving, for example, the different coupling parts opposite magnetic polarity with a magnetic contraction force fi which is in relation to the threshold value of the downward force. This means that when the coupling parts are forced apart, the rotation will not be transmitted and the coupling will thereby be disengaged.
    According to a further embodiment, the opening means 2 is provided with a locking means 32 adapted for co-operation with the sunroof, either via the locking sleeve or directly with the sunroof, in order to lock the sunroof in closed position. The locking means preferably consists of the upper part of the locking shaft 11.
    The locking member works so that when the sunroof has only a few millimeters left to the closed position, the drive shaft 8 is almost screwed into the bottom of the running sleeve 10 and the upper part of the locking shaft 11, the locking means 32, engages the bottom of the running sleeve 11 and drives the last piece. it cannot be pushed up because the drive shaft 8 has no linear locking on the locking shaft 11.
    The locking may, for example, consist of a thread which is smaller than the drive shaft, a bayonet coupling, or the like. The present invention also comprises a vehicle, for example a truck, a car or a bus, comprising a sunroof adapted to be opened and closed with at least one device as described above with reference to the guras.
    The present invention is not limited to the above-described preferred embodiments.
    Various alternatives, modifications and equivalents can be used. The above embodiments are therefore not to be construed as limiting the scope of the invention as defined by the appended claims.
