It is the object of the present invention to overcome the disadvantages of the prior art at least partially overcome and in particular to provide a way to open and close a butterfly cover in a vehicle interior, in which the associated lid body move particularly highly synchronous with each other. This option should be implemented specifically by means of a robust and durable movement mechanism, which should also be simple and inexpensive.

This object is achieved according to the features of the independent claims. Preferred embodiments are in particular the dependent claims.

The object is achieved by a movement mechanism for a cover in a vehicle (also referred to as a "vehicle interior cover"), comprising: a drive element for rotating a ("first") rotation axis for a first cover body; a first belt drive having a first pulley fixed to the first rotation axis and a second pulley; and a second belt drive having a third pulley and a fourth pulley attached to a ("second") axis of rotation for a second cover body. The second pulley and the third pulley can circumferentially engage each other in terms of torque transmission.

Thus, the first axis of rotation drives the first pulley which drives the second pulley via a commonly present belt of the first belt drive. The second pulley drives the third pulley to reverse its motion. The third axis of rotation drives the fourth pulley via a commonly present belt of the second belt drive, which in turn drives the second axis of rotation. An associated direction change is effected by the circumferential engagement of the second pulley and the third pulley.

This movement mechanism has the advantage that a movement of the first axis of rotation is transmitted as a precisely equal, opposite movement to the second axis of rotation, and vice versa. The movement mechanism is also robust, durable and easy to implement with inexpensive components. So only one drive element needs to be provided for both axes of rotation.

The engagement of the second and third pulley thus takes place via respective circumferential or lateral surfaces. By rotating one of the two pulleys, a torque is transmitted to the rotation of the other pulley.

It is a development that the first pulley is seated on the first axis of rotation, e.g. attached and / or the fourth pulley is seated on the second axis of rotation.

It is a configuration that the second pulley and the third pulley are formed as intermeshing gears. This advantageously prevents slippage of these two pulleys, which in turn supports a synchronous movement of the two axes of rotation.

It is an alternative development that the second pulley and the third pulley are frictionally connected with each other or can transmit a torque by frictional engagement.

The second pulley and the third pulley may be: freely rotating pulleys, having parallel axes of rotation, being identically shaped and / or freely rotating.

A rotation axis for a cover body may be a rotation axis provided for rotation of the cover body, in particular a rotation axis connected directly to the cover body or integrated into the cover body.

It is still a refinement that the drive element is a spring which, with the cover closed, has a spring force sufficient to open both cover bodies. Such a spring is advantageously particularly compact implemented (in particular a form of a plugged onto the axis of rotation coil spring). When closing the lid body, the spring element is elastically deformed again and stores a necessary for the subsequent opening of the lid elastic energy. A spring is robust, durable and inexpensive to implement.

It is a further embodiment that running surfaces of the pulleys are bounded laterally by upstanding walls. Thus, a slippage of the belt from the running surfaces of the pulleys is particularly sure prevented.

It is also an embodiment that a belt of the first belt drive and / or a belt of the second belt drive are designed as a toothed belt. Thus, a slip between the belt and pulleys is advantageously prevented, which in turn supports a synchronous and uniform movement of the two axes of rotation. However, the belt may in principle be designed differently, e.g. as a V-belt or as a flat belt.

It is also an embodiment that the second pulley and the third Pulley each have a tread for each belt and offset parallel to a sprocket for engagement with a sprocket of the other pulley. This advantageously allows a particularly robust and compact construction for the rotational direction-changing transmission of torques between these two pulleys.

It is also an aspect that the moving mechanism has a damping member for damping a movement of the first rotation axis. As a result, a movement speed lid body can be adjusted. In particular, too fast opening can be prevented. It only needs to be provided a damping element for damping a movement of the two lid body.

The object is also achieved by a vehicle center console with a compartment which is covered by a lid with two cover bodies, wherein the first lid body and the second lid body are arranged mirror-symmetrically to each other and the lid body by means of a movement mechanism as described above are movable. Such a lid can also be referred to as a butterfly or "butterfly" lid, the two lid body as a wing. The vehicle center console can be designed analogously to the movement mechanism and gives the same advantages.

The object is further achieved by a vehicle, comprising at least one compartment (in particular a vehicle center console), which is covered by a lid with two cover bodies, wherein the first lid body and the second lid body are arranged mirror-symmetrically to each other and the lid body by means of a movement mechanism described above are movable. The vehicle can be designed analogously to the movement mechanism and gives the same advantages.

The vehicle may be a motor vehicle (e.g., a car such as a passenger car, truck, bus, etc. or a motorcycle), a railroad, a watercraft (e.g., a boat or a ship), or an aircraft (e.g., an airplane or a helicopter).

The object is also achieved by a method for moving a vehicle interior lid with a first lid body and a second lid body, wherein a rotation axis of the first lid body is driven, a rotation of the first rotation axis is transmitted via a belt to a pulley, a rotation of this pulley is transferred by frictional engagement and / or positive locking on another, counter-rotating pulley and the rotation of the other pulley is transmitted via a further belt on a rotation axis of the second cover body. The method can be formed analogously to the above devices and gives the same advantages.

The above-described characteristics, features and advantages of this invention, as well as the manner in which they are achieved, will become clearer and more clearly understood in connection with the following schematic description of an embodiment which will be described in detail in conjunction with the drawings.

• 1 shows in a view obliquely from above a closed lid of a center console of a passenger car according to a first embodiment;
• 2 shows in a view obliquely from above an end face of the cover 1 ;
• 3 shows in a view obliquely from above a further enlarged frontal section of the lid after 1 without pulleys; and
• 4 shows in a view obliquely from above a frontal section of a lid according to a second embodiment.

1 shows in a view obliquely from above a closed ("vehicle interior -") cover 1 a center console M a passenger car F , The lid 1 can close a compartment underneath (not shown). The lid 1 has two lid bodies 2 . 3 on, wherein the first lid body 2 and the second lid body 3 arranged mirror-symmetrically to each other. The lid body 2 . 3 are by means of a common movement mechanism 4 movable, ie, hinged (as indicated by the broad arrows) and again hinged. In the closed position shown, the lid body 2, 3 are locked.

As well as in more detail 2 and more specifically in 3 shown, the movement mechanism points 4 a drive element in the form of a spiral spring 5 for rotating a first axis of rotation 6 of the first lid body 2 on. As in 3 shown points the first axis of rotation 6 a toothed section 7 on top of which a first pulley 8th is pluggable.

Returning to 2 is the first pulley 8th on the first axis of rotation 6 attached and provides a toothed tread 18 for a first toothed belt 9 ready. The tread 18 is laterally by upstanding walls 10 limited to a slipping of the belt 9 to prevent.

The timing belt 9 also runs on a toothed tread of a freely rotating second pulley 11 , Their tread is bounded laterally by upstanding walls. The first pulley 8th , the first timing belt 9 and the second pulley 11 form a first belt drive 8th , 9, 11.

The second pulley 11 also has a sprocket 12 on that in a sprocket 13 a freely rotating third pulley 14 intervenes. Over the two sprockets 12 and 13, a torque may be transmitted, wherein the second pulley 11 and the third pulley 14 have an opposite sense of rotation. The second pulley 11 and the third pulley 14 are therefore also designed as intermeshing gears. The running surfaces for the toothed belt 9 respectively. 15 are parallel to the sprockets 12 and 13 added. The second pulley 11 and the third pulley 14 can be uniform.

The third pulley 14 also has a laterally limited and toothed tread in which a second toothed belt 15 running. The second toothed belt 15 runs at its other end on a toothed and laterally limited tread of a fourth pulley 16 , The fourth pulley 16 is by twisting attaching to a "second" axis of rotation 17 the second lid body 3 attached. The third pulley 14 , the second timing belt 15 and the fourth pulley 16 form a second belt drive 14 to 16 ,

The belt drives 8th . 9 . 11 and 14 to 16 can have a gear ratio between the first pulley 8th and the fourth pulley 16 of i = 1 effect. A rotation of the first axis of rotation 6 Thus, in particular in a precisely equal, but reversed in its direction of rotation rotation of the second axis of rotation 17 implemented as indicated by the curved arrows.

The lid 19 can be similar to the lid 1 be formed, but now points to the first axis of rotation 6 in addition a damping element 21 for damping a movement of the first axis of rotation 6 on.

To open the lid 1 or 19 this is first released from its lock, for example by manually pressing one of the lid body 2 or 3 ( "Push-to-open"). With loosening the locking the spiral spring exercises 5 a torque on the first axis of rotation 6 out, so that the first lid body 2 turns, in the views shown counterclockwise. With rotation of the first axis of rotation 6 is about the belt drive 8th . 9 . 10 also the second pulley 11 shot in the same direction. This will turn the third pulley 14 rotated in the opposite direction, ie clockwise. The rotation of the third pulley 14 is about the belt drive 14 to 16 on the second axis of rotation 17 which then also rotates clockwise, precisely at the same time and at the same absolute angle of rotation as the first axis of rotation 6 , The rotation continues until the lid body 2 and 3 have reached their open end position.

To close the lid 1 or 19 under precise synchronous movement of the lid body 2 and 3 only needs one of the lid body 2 and 3 be pushed back to its original position or rest position, for example, until the lock engages again. The other lid body 3 respectively. 2 is through the movement mechanism 4 respectively. 20 moved.

Of course, the present invention is not limited to the embodiment shown.

Generally, "on", "an", etc. may be taken to mean a singular or a plurality, in particular in the sense of "at least one" or "one or more" etc., unless this is explicitly excluded, e.g. by the expression "exactly one", etc.

Also, a number may include exactly the specified number as well as a usual tolerance range, as long as this is not explicitly excluded.
