From the prior art numerous handles are known, which are arranged on a movable part of a motor vehicle, in particular on a door in order to open this movable part. In the more modern vehicles, a locking and / or unlocking of a locking mechanism, the part of a security system and / or a Central locking of the motor vehicle can be by an external mobile identification transmitter (ID transmitter). In addition, known handles can be equipped with a lock cylinder, so that the function of the mobile ID transmitter can also be taken over mechanically by the lock cylinder in an emergency. However, since the lock cylinder is used only in an emergency, when the ID transmitter or the vehicle-mounted electronics are not functioning properly, the lock cylinder is covered by a cover member. As from the publication DE 10 2008 031 218 A1 is known, a mechanical key must be used to remove the cover, so that the access to the lock cylinder is free. One possible problem, however, is that the completely detachable from the handle cover can be lost.

Object of the present invention is to provide a handle which prevents the above-mentioned disadvantages, in particular to provide a handle in which the cover remains safe and captive on the door handle.

The object is solved by all features of independent claim 1. In the dependent claims preferred embodiments are carried out.

According to the invention, the cover element is movable between a closed position and an open position, the cover element being connected to the housing shell both in the closed position and in the open position. It is particularly advantageous that the cover is arranged in any position on the door handle, in particular on the housing shell. This means that the cover is held captive on the housing shell of the door handle both in the closed position and in the open position. In the normal case, the cover is in the closed position, the normal case is defined as the usual application of the door handle, wherein the cover completely covers the lock cylinder in its closed position. The emergency occurs when the lock cylinder is to be operated with a mechanical key, for example, because the ID transmitter or the corresponding on-board electronics for the safety system of the motor vehicle does not work properly. The safety system of the motor vehicle may include an access authorization system and / or a central locking system of the motor vehicle. The electronics unit, which is integrated in the housing shell, can have various functions. For example, the electronics unit a Detecting or recognizing the user's approach to the door handle. It is also conceivable that the electronic unit can detect a touch of the door handle. Thus, it is conceivable that the electronic unit may have one or more sensors that can detect a touch of the door handle or an approach to the door handle. In addition, it is conceivable that the electronics unit can fulfill other functions, for example the function of a vehicle ambient lighting emanating from the door handle. It is also conceivable that the electronics unit can be used to heat the door handle.

Furthermore, it may be conceivable that a joint is provided on the housing shell, whereby the cover is rotatably movably disposed on the housing shell. The joint is advantageously provided on the inside in the housing shell, so that the joint is arranged invisibly to the outside of the housing shell. Advantageously, the cover is held locked in its closed position. For example, the cover may have resilient latching elements which engage positively in the closed position and / or non-positively on the housing shell. Also, the cover may have alternative fasteners, which ensure that the cover is reliably held in the closed position.

In a further measure improving the invention, the cover element may be at least partially adapted to the geometric shape of the housing shell. For example, it is conceivable that the door handle and / or the housing shell has a curved shape and / or is formed banana-shaped. It is advantageous that the housing shell so receives the cover in the closed position, so that the outer surface of the cover and the outer surface of the housing shell are flush with each other.

Advantageously, the cover may have at least one arm which extends inside the housing shell and is connected to an axis, so that the cover member is movable about the axis between the closed position and the open position. Likewise, the handle according to the invention can have two mutually parallel arms, which are connected to the axle. In one possible embodiment of the invention, the arm or arms forms a monolithic, with the cover member, common component. Advantageously, the cover as well as the one or more molded arms is an injection molded part made of plastic.

According to the invention, the door handle may be formed of a plurality of housing shells, wherein advantageously on the housing shell, which faces away from the door handle, the cover is rotatably mounted. The housing shell or the housing shells are advantageously designed as a plastic injection-molded part. In addition, it is conceivable that the outside of the housing shell or the housing shells are provided with a color layer and / or a painted paint layer, which corresponds in particular to the color layer and / or the Lackierschicht the door of the motor vehicle.

Furthermore, the handle according to the invention is designed such that the axis is arranged inside the housing shell. For example, the invention includes that the axis is formed by a shaft, wherein in particular the shaft and the cover member and / or the arm form a monolithic component. As a result, the ease of installation of the cover, including the shaft and the arm is increased in the handle according to the invention.

Furthermore, the handle according to the invention comprises a receptacle with a bearing wall which lies between two arms of the cover. In the closed position, the shaft is advantageously against the bearing wall. During the pivoting of the Covering element between the shooting position and the open position can be reliably absorbed forces from the bearing wall, which can act on the bearing wall of the shaft. As a result, a longevity of the joint is ensured.

Furthermore, the invention includes that the cover is attached via a latching connection and / or clip connection to the housing shell. It is conceivable that the arm or the arms including shaft are inserted into the inner region of the housing shell via an opening in the housing shell until the mounting position of the shaft in the receptacle of the housing shell is reached. The housing shell may be formed with a second opening, behind which the lock cylinder may be located. The cover may be formed with a closure element which is located in the closed position of the cover in the second opening of the housing shell and thus completely covers the lock cylinder. The closure member may be formed as a plug to reliably close the second opening.

Advantageously, an outer region of the housing shell adjacent to the cover element can be at least partially deformable in order to allow the cover element to be moved out of the housing shell. The deformability of a region of the housing shell favors that the user, for example, grip the cover, contact, etc., in order to move the cover from the closed position into the open position and / or to be able to better detach the cover from the closed position. For example, it is conceivable that the cover member is manually gripped by the user to move the cover member in the open position. It can also be provided that the cover element can be moved out of the closed position via a tool that the user carries with him. The deformable region of the housing shell may, for example, be provided in the region of the closure of the covering element in order to be able to reliably engage the closure, thereby allowing the covering element to be moved out of the closed position. The handle according to the invention also includes that the deformable region of the housing shell is located in the vicinity of the first opening of the housing shell, through which the arm or the arms extend in the direction of the shaft.

Alternatively and / or additionally, the cover element may be arranged on the housing shell in such a way that the cover element moves from the closed position into the open position via a defined pressure acting on the cover element. For example, the handle according to the invention can be embodied with a spring element which acts on the cover element, wherein after the action of the defined pressure force on the cover element, the spring element presses the cover element from the closed position into the open position.

Furthermore, the handle according to the invention may have on the outside of the housing shell a receptacle in which the cover is in its closed position. In the open position, however, the cover is at least partially detached from the recording. This means that in the open position, the cover at least partially spaced for receiving the housing shell is located. The receptacle is located on the outside of the housing shell. For example, the recording may be groove-shaped, in which the cover is in the closed position. Advantageously, the receptacle is substantially adapted to the geometry of the cover.

Further, it is conceivable that the receptacle has an extension along the housing shell, wherein in the receptacle adjacent to the cover a decorative strip is inserted, in particular the outside of the decorative strip and / or the outside of the cover have a chromium material. It can also be provided that in the receptacle of the housing shell, only the cover is located, wherein the cover takes over the function of the decorative strip in a possible embodiment of the invention. For example, the cover may extend approximately along the entire extent of the housing shell and / or the door handle.

According to the invention, the cover member may have a length which is more than 60% of the length of the housing shell, in particular more than 75% of the length of the housing shell. It is conceivable that the cover without decorative strip is arranged on the door handle or alternatively that the cover extends together with the decorative strip on the door handle.

In a measure improving the invention, the door handle may be formed as a movable door handle, wherein the door handle has a bearing arm which acts on an axis, wherein the door handle on the door of the motor vehicle is pivotable. Advantageously, the entire door handle can be pivoted, wherein at the same time the cover is pivotable. The door handle may be formed with an extension which projects into the door to trigger an action during pivoting of the door handle, which causes, for example, an opening of the door lock. For example, it is conceivable that the extension is connected via a transmission means, in particular a Bowden cable with the door closing to bring the door lock during pivoting of the door handle out of the door from its closed position to the open position. It is particularly advantageous that a door handle can be created, the production cost is low. In contrast to the prior art, in which at least a portion of the handle remains immobile at a pivoting of the door handle on the door, the handle according to the invention has a door handle, which is pivoted completely upon actuation about the axis.

a further embodiment of a handle, which is inserted in the door of the motor vehicle.

In FIG. 1 schematically a motor vehicle 2 is shown, which is equipped with a handle 100 on the motor vehicle door 8. The handle 100 has a door handle 1 located on the outside of the door 8 for the user. In the door handle 1, an electronics unit 40 may be arranged, for example, in FIG. 7 is provided with a reference numeral 40. The electronic unit 40 may be part of a security system 4, for example, which is located in the motor vehicle 2. The security system 4 may include an access authorization system and / or a central locking system of the motor vehicle 2. Also, the electronics unit 40 may include other functions, such as lighting the motor vehicle 2 in the exterior of the door 8. Likewise and / or additionally, the electronics unit 40 may have sensors which serve to detect the user who, for example, wants to lock or unlock the motor vehicle. As a rule, the user can carry a mobile identification transmitter (ID transmitter), whereby these access systems can be active entry systems or passive entry systems. In an active-entry system, the user deliberately operates a switch on his ID transmitter, whereby an identification check between the motor vehicle 2 and the ID transmitter takes place. It is also conceivable that according to a defined pattern, for example by approaching the door handle 1 or by touching the door handle 1, the identification process is started. In this case, the ID transmitter may be implemented as a type of smart card that the user carries with him. In both cases, that is to say both in the active entry system and in the passive entry system, data communication or an identification check takes place between the motor vehicle 2 and the ID transmitter, which the user carries with him.

If now the mobile identification transmitter or the motor vehicle-side electronics together with the safety system 4 should have failed, the handle 100 according to the invention allows according to FIG FIG. 1 in that the user can actuate or open the lock 9 of the door 8 via an emergency key which is not explicitly shown.

According to FIG. 3 the handle 100 of the invention has a lock cylinder 3 which is disposed within the door handle 1. The lock cylinder 3 is located within a housing shell 10 of the door handle 1. The mounting axis 37 of the lock cylinder 3 is also shown. According to the illustrated embodiment, the door handle 1 on a plurality of housing shells 10 which form a cavity in the assembled state, in which, for example, the electronic unit 40 is arranged. In the present embodiment according to FIG. 3 However, only the outer housing shell 10 is shown as an example.

As in FIG. 3 is schematically shown, the housing shell 10, a cover 30, which covers the lock cylinder 3 from the outer region 5 of the housing shell 10. In this case, the cover 30 is in the closed position I. In order to release the cover 30 of the housing shell 10 to expose the case in the housing shell 10 locking cylinder 3 for emergencies, the cover 30 from the closed position I to a hinge 11th , 32 are moved to the open position II. The open position II is shown schematically in dashed lines.

As in FIG. 3 is shown, the cover 30 is rotatably movably disposed on the housing shell 10, wherein the cover 30 is simultaneously adapted to the geometric shape of the housing shell 10. This means that the cover member 30 follows the curved shape of the housing shell 10. As in FIG. 3 and FIG. 6 is clarified, the cover 30 has two parallel arms 31 which extend on the inside of the housing shell 10 in the direction of an axis 32 itself. The cover 30 is in this case movable about the axis 32 between the closed position I and the open position II. It is also conceivable to provide only one arm 31 on the cover element 30, which runs between the axis 32 and the actual cover element 30.

The axis 32 is located inside the housing shell 10, wherein at the same time the axis 32 is formed by a shaft 32 which is integrally connected in the illustrated embodiment with the arms 31 and the cover member 30. In the specifically illustrated embodiment, the shaft 32, the cover member 30 and the arms 31 forms a monolithic component. As FIG. 6 further clarified, the housing shell 10 is formed with a receptacle 11 in which the shaft 32 is located. Here, the receptacle 11 has a bearing wall 12 which lies between the two arms 31 of the cover 30. The arms 31 extend from the outer region 36 of the cover 30 in the direction of the shaft 32 and have a curved course. The housing shell 10 has a first opening 17 and a second opening 18, wherein the arms 31 extend through the first opening 17. At the second opening 18, a closure 34 of the cover 30 is held positively and / or non-positively. The closure 34 may be formed with locking elements, so that the cover 30 remains reliably in its closed position I. In FIG. 5 is shown that the closure 34 is formed with locking elements 33 which are held in a form-fitting manner on the housing shell 10 in the closed position I of the cover 30.

During assembly of the cover 30, the arms 31 are guided through the first opening 17 and then carried an attachment of the shaft 32 to the receptacle 11 of the joint.

In FIG. 3 Now different examples are shown to bring the cover 30 from its closed position I. For example, it is conceivable that the housing shell 10 has a deformable outer region 13, which is arranged adjacent to the cover 30. For example, it is conceivable that the deformable region 13 is arranged adjacent to the closure 34. The user can, for example, deform the region 13 over a defined compressive force, whereby the positive and / or non-positive fit of the closure 34 can be lifted from the housing shell 10, whereby the cover 30, for example "automatically" from the closed position I to an open position II or in the direction of open position II moves. For example, it is conceivable that the movement of the cover 30 is supported and / or triggered in the direction of the open position II by a spring element which acts on the inside of the cover 30, in particular on the closure 34. This spring element is but not explicitly provided with a reference numeral. Furthermore, it is conceivable that a deformation of the area 13 of the user with an auxiliary tool, in particular with the emergency key on the cover 30, in particular attack on the closure 34 to manually remove the cover 30 from the closed position I and in the direction of the open position II to move.

It is also conceivable that the deformable region 13 is arranged on the opposite side of the closure 34, which means that this region 13 is provided in the vicinity of the joint 11, 32, to the right of the covering element 30. About a corresponding pressurization of this area 13, the closed position I can be solved. In this embodiment, too, a spring element can support the movement of the cover element 30 from the closed position I in the direction of the open position II.

In a further alternative, it is also conceivable that according to FIG. 3 the cover 30 is thereby brought out of the closed position I by a defined acting pressure force is applied to the cover 30, which is the trigger time that the cover 30 moves in the open position II. In this embodiment, too, a spring element can support or execute the movement of the cover element 30 in the direction of the open position II.

As FIG. 2 to FIG. 5 clarify, the housing shell 10 on the outside a receptacle 14. In this receptacle 14, the cover 30 is in its closed position I. In the open position II, the cover 30 is almost completely spaced from the receptacle 14. The receptacle 14 has an extension along the housing shell 10, wherein in the receptacle 14 adjacent to the cover 30 a decorative strip 15 is inserted, which is also in FIG. 4 is shown. The outer side 16 of the decorative strip 15 has a material made of chrome. According to FIG. 2 the length of the decorative strip 15 is greater than the length of the cover 30. Alternatively, it is conceivable that the cover 30 has a length that can lie completely in the receptacle 14, so that can be dispensed with a decorative strip 15. In this case, it is conceivable that the cover member 30 may have an outer side 36 with a material of chromium.

According to FIG. 7 a door handle 1 is shown, which has a bearing arm 6 which is rotatably mounted within the vehicle door 8 on an axis 7. The inventive handle 100 according to the FIGS. 2 to 6 is on a door handle 1 according to FIG. 7 applicable. About a pivoting of the door handle 1 about the axis 7, the cover 30 is simultaneously pivoted with. In addition, the handle 100 has an extension 19 which, like the bearing arm 6, likewise projects into the vehicle door 8 in order to trigger a triggering of a signal and / or an action for closing or opening the door lock 9.

It is also conceivable that, independently of the extension 19, a differently constructed movable door handle 1 is used within the handle 100 according to the invention. The essential core of the invention is inter alia that with a movable door handle 1, the cover element 30 can always be moved, which in the closed position I reliably covers the lock cylinder 3.
