    Brief description: Roof blind system for a motor vehicle and method for mounting a roof blind system for a motor vehicle
    Description
    The invention relates to a roof blind system for a motor vehicle and to a method for mounting a roof blind system for a motor vehicle.
    Roof roller blind systems with a spring drive and a winding shaft with material attached thereto are known from the prior art. The spring motor is usually connected at two ends to a holder of the roof roller system.
    The installation costs for such a roller blind systems are high because when mounting the system both ends of a prestressed spring motor must be secured against twisting.
    The object of the invention is therefore to provide a roof blind system that is easy to assemble.
    The object is achieved according to the invention by a roof roller blind system for a motor vehicle, with a spring cassette and a winding shaft, the winding shaft having a non-circular inner section, an end part of the spring cassette contacting the inner section of the winding shaft at least partially torque-transmitting. As a result, the spring cassette is at one of its ends in rotation-proof communication with the winding shaft. Torque applied to the winding shaft (for example, when the roof roller blind system is pulled out), can therefore be transferred directly from the winding shaft to the spring cassette. Pulled out in this case means that dust is unrolled from the winding shaft, wherein in particular solar radiation is reduced through a roof opening of the motor vehicle in the interior of the motor vehicle. Similarly, a resetting moment of the spring cassette is transmitted directly to the winding shaft. When mounting the roller blind system, only one end of the spring cassette must be secured against rotation with respect to the winding shaft.
    The spring cassette preferably has a widened portion in the region of the end part which is in a torque-transmitting connection with the inner section of the winding shaft. In particular, the widening is formed integrally with the spring cassette. A torque exerted on the winding shaft can thus be transmitted particularly well to the spring cassette. Similarly, a resetting moment of the spring cassette can be transferred particularly well to the winding shaft.
    It is more preferably provided that between the widening of the end part of the spring cassette and the inner section of the winding shaft, seen in the circumferential direction, there is a positive connection. As a result, the connection has little play, so that disturbing noises with a change of direction of rotation of the winding shaft are reduced.
    One aspect of the invention provides that the spring cassette has an inner rod, a first spring gripper, a second spring gripper and a spring, wherein end parts of the spring are slid onto a spring gripper and the spring grippers are coupled to the inner rod. The spring cassette thus forms a pre-assembled structural unit. This structural unit can then be used in various roof roller systems. The inner rod prevents the spring from turning over when the rotation tension is too high.
    According to a further aspect, the first spring gripper and the second spring gripper are connected to the inner rod such that the first spring gripper and the second spring gripper are rotatable relative to each other. This allows the spring to absorb torques acting on the spring grippers and store the resulting potential energy.
    Preferably, at least one of the spring grippers has grooves on its outer circumference that are complementary to turns of an end portion of the spring. As a result, the spring is form-tightly rotatably connected to the spring gripper in a direction of rotation, without the spring having to be specially shaped or bent. This is advantageous because when bending the spring wire, weak spots can arise in the spring wire, which can break when transferring forces. In other words, the torque from and to the spring can be transmitted particularly reliably. If the spring is biased in the wrong direction, it will spring out of the spring gripper without being damaged. Furthermore, the spring is immovably connected to the at least one spring gripper thereby also in the axial direction of the spring to achieve a limit force.
    Another aspect provides that a widening is provided on the second spring gripper which serves for transmitting torque to the winding shaft. A torque acting on the winding shaft is thus transmitted to the spring via the second spring gripper. In the same way, a spring return moment is transmitted to the winding shaft via the second spring gripper.
    In a further embodiment of the invention, the spring device comprises a tensioning device, wherein the tensioning device is provided at an end which is opposite the end which contacts the inside section of the winding shaft in a torque-transmitting manner. A pre-tensioning of the spring cassette on the relevant roof roller blind model can be easily adjusted via the tensioning device.
    According to one aspect of the invention, it is provided that an outer end portion of the tensioning device has an outer section in the form of a simple polygon, in particular a quadrangle. As a result, the tensioning device can be secured particularly easily against rotation, because it is arranged in a recess, the inner diameter of which engages the outer diameter.
    The tensioning device is preferably provided on the first spring gripper. In particular, the first spring gripper and the winding shaft are rotatable relative to each other. As a result, the spring can also be pre-stressed after the spring cassette has been placed in the winding shaft.
    In one embodiment of the invention, a rotary securing device is provided on at least one end of the winding shaft which can be attached to at least one end of the winding shaft such that the rotary securing device and the winding shaft are fixedly connected. In particular, the rotary securing device and the winding shaft are form-tightly connected to each other. As a result, the winding shaft can also be secured against rotation about its longitudinal axis via the rotary securing device.
    The winding shaft can have at least one recess at at least one end, into which a nose of the rotary locking device complementary to the recess engages. More particularly, the nose can be designed such that the rotary securing device and the winding shaft are also fixedly connected in the axial direction of the winding shaft.
    Preferably, a recess is provided on an inside of the rotary fuse device and on an outside of the tensioning device. As a result, since the recesses are placed opposite and, for example, a threaded pin is inserted into the recesses, the rotary locking device and the clamping device can be secured against rotation relative to each other.
    According to an embodiment of the invention, a dust web is attached to the winding shaft. The fabric web can be rolled up on the winding shaft. In particular, the fabric web may already be rolled up on the winding shaft prior to mounting the roof roller blind system.
    According to another embodiment of the invention, the web of material has at least partially a plastic reinforcement at its circumference, the web of material being applied to the winding shaft by thermal welding. The dust web is thus particularly easy to attach to the winding shaft.
    Another aspect provides that the spring cassette extends over 30 - 90 percent of the length of the winding shaft, preferably over 40 - 80 percent, more preferably over 50 - 70 percent. The spring cassette must therefore not extend over the entire length of the winding shaft, so that the spring cassette can be used universally for different winding shaft lengths.
    The object is further achieved according to the invention by a method for mounting a roof blind system for a motor vehicle, with the following steps:
    mounting the spring cassette;
    retracting the spring cassette into the winding shaft;
    biasing the spring cassette;
    securing the winding shaft and the spring cassette against twisting;
    incorporating the winding shaft and spring cassette assembly into the roof roller blind system; and disconnecting the fuse from the winding shaft and turning the spring cassette against.
    The advantage of the method according to the invention is that a spring cassette which is universally applicable for different winding shaft lengths is simply slid into the winding shaft and the pre-tensioning of the spring to the respective roof roller blind model can be adjusted particularly easily by turning the tensioning device. Moreover, assembly is facilitated because only at one end of the winding shaft the winding shaft and the spring cassette must be secured against rotation relative to each other.
    With regard to the other benefits, reference is made to the above statements.
    Preferably a dust web is applied to the winding shaft, in particular by thermal welding, before the spring cassette is slid into the winding shaft. Winding shaft, dust track and spring cassette can then be built into the roof roller system as a pre-assembled unit.
    Further advantages and features of the invention will become apparent from the following description and the drawings to which reference is made. It shows:
    Figure 1 shows a longitudinal section through an end part of a roof roller blind system according to the invention;
    Figure 2 is a perspective view of a spring cassette of the roof roller blind system according to the invention of Figure 1;
    Figure 3 is a detailed view of an end portion of the spring cassette of Figure 2;

    Figure 1;
    Figure 5 is a detailed view of an end of the assembly of Figure 4;
    Figure 6 is a perspective view of the end part of the roof roller blind system according to the invention of Figure 1; and
    Figure 7 is a perspective view of an end part which is placed opposite the end part of the roof blind system according to the invention shown in the figure.
    Figure 1 shows a longitudinal section through an end part of a roof blind system 10.
    The roof roller blind system 10 serves as a sun blind roller blind of a sliding roof system of a motor vehicle. Thus, by means of the roof roller blind system 10, solar radiation in particular can be reduced through a roof opening of the motor vehicle in the interior of the motor vehicle.
    The roof roller blind system 10 comprises a spring cassette 12, a winding shaft 14 of plastic with a dust web 16 attached thereto and a holder 18.
    The structure of the spring cassette 12 is explained in more detail below with reference to Figures 1 to 3.
    The spring cassette 12 has an inner rod 20, a first spring gripper 22 attached to the inner rod 20, a second spring gripper 26 secured to the inner rod 20 and a spring 24.
    The spring 26 is in this case designed as a spiral spring and sits on the inner rod 20. A spring wire thickness of the spring 26 can be between 0.6 mm and 1.2 mm, in particular between 0.7 mm and 1.1 mm, for example 0 , 8 mm to 0.9 mm.
    Each end portion of the spring 26 is slid onto one of the spring grippers 22, 24. The spring grippers 22, 24 here each have grooves 28 on their outer circumference, which grooves are complementary to the respective end part of the spring 26. As a result, the spring 26 is connected to the spring grippers 22, 24 in a rotationally tight manner in each direction of rotation.
    The spring gripper 22, 24 are mounted on the inner rod 20 such that they are rotatable relative to each other, the inner rod 20 keeping the two spring gripper 22, 24 spaced apart.
    At the second spring gripper 24 a non-circular, here gear-like widening 30 is arranged, in particular integrally connected to the second spring gripper 24.
    A tensioning device 34 is provided on the first spring gripper 22, wherein the tensioning device 34 is fixedly mounted on the first spring gripper 22. The spring 26 can be biased in that the tensioning device 34 is rotated. An outer section 35 of the tensioning device 34 is here formed in a quadrangular shape, in particular square. However, the outer section 35 can also be in the form of another simple polygon.
    The tensioning device 34 also has a central bore 36. The bore 36 can be used to attach the spring cassette 12 to the roof blind system 10, for example by means of a bearing bolt.
    Optionally, the spring 26, as can be seen particularly well in Figure 2, can at least partially have a sleeve 32 of plastic, in particular of polyethylene. As a result, noises are damped which occur when the spring 26 bumps against components located outside the spring 26.
    Furthermore, as shown in Figure 3, the spring cassette 12 can have an outer tube 37, wherein in particular a foil 38 can be provided between spring 26 and outer tube 37.
    Figures 4 and 5 show a winding shaft 14 with the spring cassette 12 inserted therein, while in Figure 5 the spring cassette 12 is shown for better clarity with the first spring gripper disassembled.
    The spring cassette 12 here extends over approximately 65 percent of the length of the winding shaft 14. However, it is also possible that the spring cassette extends over 30 to 90 percent of the length of the winding shaft 14. In other words, the spring cassette 12 forms a spring drive which is universally usable for different winding shaft lengths.
    The winding shaft 14 has a non-circular inner section 42, the widening 30 engaging the second spring gripper 24 at least partially torque-transmitting. Via the second spring gripper 24 and the widening 30, the spring 26 is thus, viewed in the circumferential direction, in a torque-transmitting positive connection with the winding shaft 14.
    In the embodiment shown here, the inner section 42 is substantially complementary to the widening 30.
    At ten least a end from the winding shaft is 14 a rotary fuse device 44 on the winding shaft 14 fixedly mounted. The pivotal locking device 44 has a nose 46 which extends into a corresponding recess 48
    engages in the winding shaft 14 to form a form-fitting rotational connection.
    As can be seen particularly well in Figure 3, the tensioning device 34 on the outside thereof and the rotary locking device 44 on the inside thereof each have a recess 50, 52.
    Attached to an outside of the winding shaft 14 is the fabric web 16 (not shown in Figures 2 to 7 for reasons of clarity). The fabric web 16 has a plastic reinforcement at least partially on its circumference, the fabric web being attached to the wrapping shaft 14 by thermal welding of the plastic reinforcement and the winding shaft 14.
    Figure 6 shows an oblique view of the holder 18 and an assembly of winding shaft 14 and spring cassette 12. The holder 18 has a rotary securing part 54, which is configured such that the clamping device 34 with its outer diameter 35 engages tightly on the inner diameter of the rotary securing part 54. In the embodiment shown here, the rotary securing part 54 is designed as a block into which the clamping device 34 can be inserted in a form-fitting, rotation-proof manner.
    Figure 7 shows an end part of the assembly of winding shaft 14 and spring cassette 12, which is opposite the end part shown in Figure 6. The assembly of winding shaft 14 and spring cassette 12 is rotatably arranged here via a bearing bolt 56 via a connecting element 58 on the roof blind system 10.
    A method for mounting the roof blind system 10 is explained below.
    First the spring cassette 12 is mounted. To that end, the spring 26 is slid onto the inner rod 20 and the spring grippers 22, 24 are mounted on the inner rod 20. Now, the ends of the spring 26 are each slid onto one of the spring grippers 22, 24.
    In addition, the fabric web 16 is attached to the winding shaft 14 by thermal welding and rolled up.
    The pre-assembled spring cassette 12 is now slid into the winding shaft 14.
    The spring 26 of the spring cassette 12 is then prestressed in that the tensioning device 34 is rotated. When a desired bias voltage is achieved, the recesses 50, 52 of the tensioning device 34 and the rotary fuse device 44 are placed opposite each other.
    The rotary securing device 44 and the tensioning device 34 are now secured against rotation relative to each other. This is done, for example, by introducing, as shown in Figure 1, a blocking element 53, in particular a threaded pin, into the recesses 50, 52. This prevents a rotation with respect to each other of the rotary securing device 44 and the tensioning device 34. As the rotary securing device 44 and the winding shaft 14 are in a rotation-proof connection, the tensioning device 34 and the winding shaft 14 are also secured against a rotation relative to each other.
    The assembly of winding shaft 14 and spring cassette 12 is then placed in the holder 18, as a result of which the tensioning device 34 abuts tightly on the rotating securing part 54. A reset moment which the spring 26 exerts on the winding shaft 14 can therefore be supported at the rotary securing part 54.
    Both ends of the assembly of winding shaft 14 and spring cassette 12 are fixed, for example by means of bearing bolts 56, which in particular can be formed as equal parts at both ends.
    The fuse of the winding shaft 14 and the spring cassette 12 is now released against rotation. In the example shown here, the blocking element 53 is removed from the recesses 50, 52 for this purpose.
    Alternatively, the fuse of the winding shaft 14 and the spring cassette 12 against rotation can also be released even after the assembly of winding shaft and spring cassette 12 is inserted into the holder, i.e. before the assembly of winding shaft 14 and spring cassette 12 by means of the bearing bolt 56 is attached.
