Description

The invention relates to a handle for the locking device of a motor vehicle door, according to the preamble of claim 1. The handle comprises a mass balance element, which is engageable with a door handle in operative connection, wherein the mass balance element due to an effect of accelerations on the door handle in an accident act, due to its inertia prevents unintentional opening of the door, and a locking element which is movable between a rest position and a locking position, wherein in the rest position, the mass balance element is movable relative to the locking element, and in the locking position, in which the locking element due to its inertia can be deflected in an accident, the blocking element blocks the mass balance element.

It is known that handles are mounted in closing devices on motor vehicle doors, which are also called crash barriers, which are intended to prevent the vehicle door from being accidentally opened in the event of an accident. For this purpose, the conventional handle mass balancing elements, which are used due to their inertia for securing door handles.

A generic prior art is for example from the DE 10 2009 056 538 A1 known. Here, a crash barrier is provided in a closing device of a motor vehicle door, which comprises a transmission element, a mass balance element and a blocking element. The door handle and the mass balance element are pivotally mounted and interconnected via the transmission element in the manner of a rocker, that the transmission element can transmit the tensile force on the door handle in a unlocking direction opening the door lock on the mass balance element against its inertia. Since the mass balance element is made more massive than the door handle, therefore, must be pulled with sufficient force on the door handle to move the mass balance element and open the door. The blocking element is also pivotally mounted, but it is not operated in normal operation and is in a rest position. However, it can be pivoted due to its inertia in the same direction of rotation as the door handle, when the door handle is rotated to the unlocked position, so that the locking element is transferred into a locked position with respect to the mass balance element, in which the blocking element blocks the mass balance element.

In the event of an accident, impact forces and accelerations may act on the vehicle door, which may cause the door handle to be thrown in the unlocking direction that opens the door lock. The mass balance element, which is accelerated in the same direction, normally ensures that the door handle remains in its closed position. However, if in the accident the door panel, especially the outer door panel, be damaged, the mass balance element can still be pressed into its release position in which the unwanted door opening can not be prevented. The blocking element of DE 10 2009 056 538 A1 can thereby by deformation an outer door panel are transferred to its locked position to block the mass balance element.

In an intense lateral vehicle impact and a bending of the vehicle door, it may happen that not only the outer door panel can be greatly deformed, but also the inner door panel, which is directed to the interior of the motor vehicle. In the door panel then form so-called "waves". It has been found to be a disadvantage that can be converted into its unlocking position opening the door lock by these deformations of the door handle despite the mass balance element and the blocking element. In this case, the mass balance element can be pressed in the direction of opening the door. At the same time may happen that the blocking element is trapped, can no longer functionally trigger and can no longer lock the mass balance element. As a result, the vehicle door can be opened, resulting in an increased risk of injury to the person sitting in the vehicle.

From the EP 2 342 406 A1 Furthermore, a handle with a mass element and a blocking element is known, in which the blocking element prevents an unintentional opening of the door in the case of a deformation of the door panel.

It is therefore an object of the present invention to provide a handle of the aforementioned type, in which the disadvantages mentioned are at least partially overcome. In particular, it is an object of the invention to provide a handle that is simple in design and has good functionality, wherein in an intense lateral vehicle impact and / or deformation of the vehicle door reliably opening the door is prevented.

To solve this problem, a handle for the locking device of a motor vehicle door with the features of claim 1 is proposed. In the dependent claims expedient developments are carried out.

The object of the invention is achieved by a handle for a locking device of a motor vehicle door with the features of claim 1, which is provided with a mass balance element, which can be brought into operative connection with a door handle, wherein the mass balance element due to an effect of accelerations acting on the door handle at a Act accident, due to its inertia can prevent accidental opening of the door, a blocking element may be formed which can be moved between a rest position and a locked position, wherein in the rest position, the mass balance element can be moved relative to the locking element, and in the locked position, in the blocking element can be deflected due to its inertia in an accident, the blocking element can block the mass balance element. For this purpose, it is provided according to the invention that the handle has a locking element which can be moved between a release position and a locking position, wherein in the release position the locking element can be movable relative to the locking element, and in the locking position, the locking element can lock the locking element. Thus, advantageously, an additional security can be provided that no unwanted opening of the door takes place, should the blocking element by deformation of the door panel, in particular the outer door panel, which is directed to the outside, be pinched and / or disturbed in its function. The locking element advantageously ensures that when the balance of forces between the masses of the closing device is disturbed by mechanical deformation of the door panel, the door still remains closed. In this case, the locking element can be activated just by the deformation of the door panel, in particular of the inner door panel, to push the locking element back into the locking position, so that the mass balance element remains reliably locked.

Advantageously, the locking element with a mounting portion for fastening the locking element to the locking device, a sensor area for detecting a deformation of a door panel of the motor vehicle, in particular an inner door panel, which is directed to the interior of the motor vehicle, and a locking portion for locking the locking element. The locking element should advantageously the deformation of the door, in particular of the inner door panel, can detect early to lock the locking element in time in its locked position so that the locking element reliably trigger and can safely block the mass balance element. For this purpose, the sensor area is advantageously provided, which can be designed in such a way to detect the deformation of the inner door panel. The advantage of the invention lies in the fact that the sensor area can be designed such that the locking element can be transferred from a release position into a locked position only by deformation of the door panel, in particular of the inner door panel. In this case, in the release position of the locking element, the blocking element remain movable relative to the locking element, whereas in the locking position of the locking element, the locking element can lock the locking element. A particular advantage of the invention lies in the fact that the locking element alone, without further component and conversions of the locking device , ensures that the blocking element can reliably fulfill its function and that the blocking element always remains in its blocking position or is transferred to the blocking position in the event of an accident. For this purpose, the locking element according to the invention has the locking area, which can reliably hold the blocking element in its blocking position, in particular can press into the blocking position when the door panel has been deformed. According to one embodiment of the invention, the attachment portion may have a fastening means, in particular in the form of a step of a Klips-, latching, snap or hinge means to positively and / or non-positively, in particular detachably, to secure the locking element to a mounting member of the locking device , It is advantageous that any type of releasable attachment can be used to attach the locking element to existing locking device, which fits to the respective locking device to adapt the locking element to the existing circumstances. It is also advantageous that the locking element can be fixed just there on the mounting element by the appropriate locking means, where space is available and the locking element can lock the locking element. Alternatively, it is conceivable that the fastening means may be an adhesive to the locking element cohesively connect to the mounting element. It is also conceivable that the fastening region of the locking element can be welded to the mounting element, wherein in particular the fastening means can be designed in the form of a weld seam. Conceivable are also different releasable and permanent connections, which also allow the locking member pivotally and / or tiltable and / or resiliently arranged on the mounting member to ensure that the locking element at least between the release position and the locking position with respect to the locking element can be movable ,

Furthermore, the sensor region may comprise a sensor means, in particular in the form of a curved element, which, after fastening of the locking element to the locking device, can buckle towards the inner door panel of the motor vehicle in order to detect a deformation of the inner door panel by contact. Advantageously, thereby the deformation of the door panel can be transmitted directly to the locking element, wherein the sensor means can simultaneously ensure that the locking element can be pressed into the locking position.

In addition, the locking portion may have a locking means, in particular in the form of a stop surface, which can be brought into operative connection with a complementary locking surface of the locking element in a deformation of the inner door panel to lock the locking element. Advantageously, the locking surface can be formed in a wide area, in order to lie flat against the locking surface of the blocking element and thus to press the blocking element into the blocking position. The sensor means can advantageously the mechanical deformation energy of the inner door panel in the movement of the locking element from the release position in implement the locking position and / or transferred directly to the locking means, which can exert a mechanical pressure on the locking element in the locking position such that the locking element can not be deflected back to its rest position.

Advantageously, the handle can have a mounting element on which the closing device can be arranged, and on which the blocking element and the mass balancing element can be movably arranged. In and on Mounting element can advantageously be taken various components of the handle, such. B. the locking element, a lock cylinder and the like. In addition, the mounting element can have surfaces and areas which can serve for fastening the closing device on the door panel. In addition, the mounting element may advantageously have protective walls and / or side surfaces that can protect the components of the handle against eventual side effects in case of an accident.

Advantageously, the handle between the outer door panel on which the door handle can be arranged, and an inner door panel, which may be directed to the interior of the motor vehicle, be arranged. It is important here that in the event of an accident, if one of the door panels or even both can be deformed, the handle can nevertheless provide the occupants with security, in particular ensuring that the door is not unintentionally opened. The handle according to the invention is advantageously designed and arranged between the door panels such that even in the case of deformation of the door, the door handle can not be unintentionally pivoted to open the door. According to the invention, the deformation of the door panel, in particular, when both door panels are deformed in "waves", are used to control the locking element, which can lock the locking element, which in turn can block the mass balance element, which then blocks the opening of the door.

For this purpose, it may be provided according to the invention that the locking element can be transferred by deformation of a door panel, in particular an inner door panel, which is directed to the interior of the motor vehicle in an accident in the locked position. According to the door panel in an accident directly contact the locking element and actuate this, wherein the locking element can be pressed from its release position into the locking position to transfer the blocking element from the deflected position back into the blocking position. The advantage here is that a secure operation of the locking element can be safely ensured in a deformed door. Bounces z. As a car in this door and deforms it, the locking element can be deflected from the rest position, but wherein the locking element exploits the pressure exerted on the bent vehicle door pressure force to push the locking element back into the locked position. In this case, the blocking element with the mass balance element such cooperate, that the mass balance element can not move into an unlocking position opening the door lock, whereby an unintentional opening of the door is prevented.

The inventive idea may also provide that the locking element can be positively and / or positively and / or cohesively attached to the mounting member to advantageously upgrade the existing locking devices. At the same time it is conceivable that the locking element can be mounted either releasably or permanently on the locking device. Thus, it can be advantageously ensured that the locking element can be flexibly adapted to existing geometries and features.

According to the invention, the mass balance element may comprise an actuating lever, with which the locking device, in particular the door handle, may be in communication. Advantageously, the mass balance element and the actuating lever can be firmly connected to each other. In addition, it is conceivable that the mass balance element and the actuating lever can be monolithic, of the same material and / or in the form of a component. Furthermore, a transmission element may be provided to transmit the tensile force on the door handle on the mass balance element. The actuating lever and the transmission element can thus ensure that a kind of rocker is formed between the door handle and the mass balance element, which is normally used to open the door and ensures during accelerations and in crash cases that the inertia of the mass balance element tilting the Rocker and thus prevents the pivoting of the door handle in the unlocked position.

Another advantage of the present invention is that the mass balance element spring-loaded, in particular in a locking position locking the door handle, and / or can be rotatably mounted about an axis. As a result, the handle can be stabilized when accelerations occur by the supporting action of a spring element, such as a rotary, compression or coil spring. In an accidental vehicle collision, the mass balance element can automatically by its inertia about the axis in the door closing the locking position pivot. When no longer acting vehicle impact, the mass balance element can return due to the spring effect in an unlocking position by pivoting, in which the door can be opened again. In case of accidental accelerations, the blocking element can move into the blocking position in which the mass balance element is securely held, in which the door handle is blocked against a displacement of the mass balance element in an unlocking position opening the door lock.

Advantageously, the blocking element may be spring-loaded, in particular in the release position, and / or rotatably supported about an axis. For example, a spring element can be used to compensate for oscillating movements of the locking element to stabilize the handle in case of accidental accelerations, in particular, the spring element z. B. may be a rotary, pressure, coil spring or the like. In an accidental vehicle collision, the blocking element can pivot by its inertia automatically about the axis in the locked position. When no longer acting vehicle shock, the blocking element can pivot back into the rest position due to the spring action. In case of accidental accelerations, the blocking element can move into the blocking position in which the mass balancing element is blocked in the locking position. In case of accidental deformation of the door causes the locking element according to the invention, that the locking element is reliably held in the locked position or transferred to the locked position.

In the invention, furthermore, the axis of the mass balance element may be spaced and arranged parallel to the axis of the blocking element. Moreover, it is advantageous that the mass balance element and the blocking element can be rotatably mounted on the mounting element such that they can be pivoted in accelerations in the same directions of rotation. This can ensure that the pivotable movement of the mass balance element from the unlocking position in the locking position can be parallel and undisturbed by the pivotal movement of the locking element from the rest position into the locked position. These movements can be prevented by the parallel arrangement of the axes that the accelerations acting on the door handle in the door opening unlocking position are reliably intercepted. At opposite accelerations, on the door handle in the the door closing locking position act, the mass balance element in its unlocked position and the locking element in its rest position can swing back undisturbed.

Furthermore, the blocking element according to the invention may comprise a blocking means, which in the blocking position of the blocking element can be brought into operative connection with a complementary blocking nose of the mass balancing element in order to block the mass balancing element. Consequently, the advantage can be achieved that in the locked position of the locking element a secure hold for the mass balance element is offered, the locking means can press against the locking lug so that the mass balance element can not unintentionally pivot in the unlocking position.

Further advantages, features and details of the invention will become apparent from the following description. An embodiment of the invention will be described in detail with reference to the drawings. Show it:

The FIG. 1 shows a conventional handle 1 according to the prior art, which is also referred to as a crash lock. The handle 1 is mounted in locking devices on motor vehicle doors 100 between an outer 101 and an inner door panel 102 and is intended to prevent a door handle 110 in the event of an accident from a locking position 110a pivoted into an unlocked position 110b, and that the vehicle door is opened unintentionally. For this purpose, the conventional handle 1 is designed with a mass balance element 10, which is used due to its inertia M for securing the door handle 110. The handle 1 has a transmission element 14, which forms a kind of rocker between the door handle 110 and the mass balance element 10. The mass balance element 10 is mounted so pivotable about an axis 12 that the transmission element 14 forms the lever of the rocker. The transmission element 14 can transmit the tensile force Z on the door handle 110 in an unlocking direction 110a that opens the door lock to the mass balance element 10 against its mass force M. Since the mass balance element 10 is made more massive than the door handle 110, a tensile force Z must be applied to the door handle 110, which exceeds the mass force M of the mass balance element 10 to open the door. In addition, the conventional handle 1 has a blocking element 20 which blocks the mass compensation element 10 against acceleration in the unlocking position 10a releasing the door handle against acceleration. The blocking element 20 is also pivotally mounted about an axis 22. In normal operation, the blocking element 20 is not actuated and it is in a rest position 20a. However, in case of accelerations I, which may lead to the door opening, the blocking element 20 can be pivoted in the same direction of rotation S due to its inertia m as the mass balance element 10, when the door handle 110 is rotated into the unlocked position 110a. Thus, the blocking element 20 can be converted into a blocking position 20b with respect to the mass balance element 10, in which the blocking element 20 blocks the mass balance element 10. The accelerations II, which act on the components of the handle 1 in the direction from outside to inside, while the mass balance element 10 in the unlocking position 10 a and the blocking element 20 in the Resting position bring 20a, but they act on the door handle 110 in the door closing locking position 110b and therefore are not dangerous for the opening of the door.

In an accident, however, not only accelerations I and II can act on the vehicle door, but also impact forces I and II, which can cause the door handle 110 is thrown in the door lock opening unlocking direction 110a. The mass balance element 10, which is accelerated in the same direction S, ensures in the normal case that the door handle 110 still remains in its locking position 110b. However, in the accident, the outer 101 and / or inner door panel 102 should be damaged, as for example in the FIG. 2b is shown, the mass balance element 10 can be inadvertently pressed into its unlocked position 10a, in which the unwanted opening of the door can not be prevented. The blocking element 20 can also be unintentionally transferred by deformation of the outer 101 and / or the inner door panel 102 in its rest position 20a, in which the mass balance element 10 can not be locked.

With a strong lateral vehicle impact and a bending of the vehicle door, it may thus happen that the blocking element 20 can be clamped in the rest position 20a and can no longer functionally trigger. To avoid this, the invention proposes to provide a locking element 30 for the blocking element 20, which can reliably lock the blocking element 20 in the blocking position 20b in the event of deformation of the door panel 10, 102, in particular of the inner door panel 102, in order to prevent accidental opening to prevent the door.

The FIGS. 2a and 2b show a locking member 30 for a locking element 20 and a handle 1 according to the invention for the locking device of a motor vehicle door in each case in normal operation (see the FIG. 2a ) and deformation of the motor vehicle door 100 after an accident (see the FIG. 2b ).

The locking element 30 is in this case provided with a fastening region 31 for fastening the locking element 30 to the locking device, a sensor region 33 for detecting a deformation of a door panel 101, 102 of the motor vehicle, in particular the inner door panel 102, and a locking region 35 for locking the blocking element 20 executed. A first advantage of the locking element 30 is that the locking member 30 can be retrofitted in existing locking devices without having to rebuild the locking devices. For this purpose, the mounting portion 31 is provided, which is designed to secure the locking member 30 in existing locking devices. The locking element 30 according to the invention also has the advantage that it can reliably detect the deformation of the motor vehicle door 100, in particular of the inner door panel 102 of the motor vehicle door 100, and can lock the blocking element 20 in the locking position 20b. The locking member 30 thus enables a reliable operation of the locking element 20, which can securely lock the mass balance element 10 in an accident. For this purpose, the sensor region 33 is provided according to the invention, which is formed in such a way to detect the deformation of the inner door panel 102. Furthermore, the advantage of the invention that the sensor portion 33 is formed such that the locking member 30 can be driven solely by the deformation of the inner door panel 102 to lock the locking element 20 (see FIG. 2b ). The locking member 30 can between a release position 30 a of FIG. 2a and a locking position 30b of FIG. 2b to be moved. Like in the FIG. 2a can be seen, the blocking element 20 remains in the release position 30a of the locking member 30 is still movable relative to the locking member 30. Like in the FIG. 2b can be seen, the blocking element 20 is locked in the locking position 30 of the locking element 30 by the locking member 30. To lock the blocking element 20, the locking element 30 according to the invention has the locking area 35, which can reliably hold the blocking element 20 in its blocking position 20b or can press it into the blocking position 20b should the door panel 101, 102 be deformed in the event of an accident.

As in the FIGS. 2a and 2b can still be seen, the attachment portion 31, a fastening means 32 which is formed in the form of a step to secure the locking member 30 positively and releasably attached to a mounting member 40 of the locking device. As a result, the locking element 30 can tilt over the step 32 from the release position 30a into the locking position 30b. Alternatively, however, it is conceivable that any type of releasable fasteners may be used to attach the locking member to existing locking devices, such as a clip, latch, snap or hinge means, preferably a living hinge.

Further, it is conceivable that the fastening means 32 may be an adhesive to connect the locking member 30 cohesively with the mounting member 40. Furthermore, it is possible for the fastening means 32 to be designed in the form of a weld in order to weld the locking element 30 to the mounting element 40. In addition, it is conceivable that the fastening region 31 may be elastic or resilient in order to enable the locking element 30 to cushion between the release position 30a and the locking position 30b. Advantageously, the locking element 40 may be movably mounted on the mounting member 40. It is also conceivable that the locking element 40 may be an integral part of the mounting member 40.

Furthermore, the FIGS. 2a and 2b can be seen that the sensor portion 33 has a sensor means in the form of an arc member 34 which bulges toward the inner door panel 102. The sensor means 34 thus allows deformation of the inner door panel 102 to be detected by touch. The inventive idea lies in the fact that the deformation of the inner door panel 102 is transmitted directly to the locking member 30, wherein the inner door panel 102 can press on the sensor means 34 and the locking member 30 can transfer into the locking position 30b.

At the foot of the locking portion 35, a locking means 36 may be formed in the form of a widened stop surface 36, which presses upon deformation of the inner door panel 102 on a complementary locking surface 23 of the locking element 20 to lock the locking element 20. Like in the FIG. 2b is illustrated, the sensor means 34 absorbs the mechanical deformation energy of the inner door panel 102 and sets in the movement of the locking member 30 from the release position 30a in the locking position 30b, whereby a mechanical pressure on the locking member 20 is applied to the locking member 20 in depress the locking position 20b, so that the blocking element 20 can not be deflected into the rest position 20a.

Like in the FIG. 2a can be seen, the locking member 30 is inactive in normal operation. For accelerations I, which act in the outward direction and can lead to the opening of the door, the mass balance element 10 and the blocking element 20 are also in normal operation. They are both mutatis mutandis charged in the direction of rotation S, in which the mass force M of the mass balance element 10, the tensile force Z on the door handle 110th predominates and the mass force m of the blocking element 20, the mass balance element 10 additionally protects. Like in the FIG. 2b can be seen accelerations II from the outside and door deformations II can cause the mass balance element 10 and the locking element 20 can be pressed unintentionally in the release position 30a or rest position 20b, whereby the door handle 110 can be transferred to the unlocked position 110a. However, the locking element 30 according to the invention provides a simple yet secure means which prevents the unwanted scenario by the locking member 30 is pressed in the direction of rotation S from its release position 30a in the locking position 30b. In the locking position 30b of FIG. 2b can the blocking element 20 and thus also the mass balance element 10 are not pivoted in the direction of rotation E, so that an accidental opening of the door is prevented.

The Figures 3 and 4 show the handle according to the invention in a perspective view of two different viewing directions, from outside to inside (see the FIG. 3 ) and from the inside out (see the FIG. 4 ). The handle 1 in this case comprises a mass balance element 10 which can be brought into operative connection with the door handle 110, wherein the mass balance element 10 due to an effect of accelerations I, which act on the door handle 110 in an accident, due to its inertia M unintentional opening of the door can prevent a blocking element 20 which can be moved between a rest position 20a and a blocking position 20b, wherein in the rest position 20, the mass balance element 10 can be movable relative to the blocking element 20, and in the blocking position 20b, in which the blocking element 20 due to its inertia m can be deflected in an accident, the blocking element 20 can block the mass balance element 10. The handle 1 also has an inventive locking element 30, which above with reference to FIGS. 2a and 2b has been described in detail. The locking element 30 can between a release position 30a (see the FIGS. 2a and 3 ) and a locking position 30b (see FIGS FIGS. 2b and 4 ), wherein in the release position 30a the blocking element 20 can be movable relative to the locking element 30, and in the locking position 30b the locking element 30 locks the blocking element 20. Thus, the locking element 20 is secured according to the invention, so that the blocking element 20 is supported even in the case of deformation of the door panel 101, 102, in particular of the outer door panel 101, after an accident in its blocking function. The locking element 30 makes it possible that when the balance of forces between the masses 10, 20 and 110 is disturbed by mechanical deformation of the door panel 101, 102, as it is sketchy in the FIG. 2b is indicated, the door still remains closed. The inventive idea lies in the fact that the locking element 30 is activated just by the deformation of the door panel 101, 102, in particular of the inner door panel 102, to press the locking element 20 in the locking position 20a, so that the mass balance element 10 remains locked in the locking position 10b.

The handle 10 is arranged on a mounting member 40, which serves for fastening the closing device and for the movable receiving of the blocking element 20 and the mass balance element 10. The mounting member 40 has not shown surfaces and areas to secure the locking device to the door between the outer door panel 101 and the inner door panel 102. The task of the handle 1 is in an accident when one of the door panels 101, 102 or both are deformed to ensure the safety of the occupants, in particular to ensure that the door remains closed. Rather, the handle 1 according to the invention utilizes the deformation of the door panel 101, 102 in order to control the locking element 30 in the locking position 30b. The locking element 30 in the locking position 30b loads the blocking element 20 in the direction of rotation S into the blocking position 20b, in which the blocking element 20 blocks the mass balance element 10 in the locking position 10b. As it is in the enlarged section of the FIG. 4 as well as in the FIG. 2b is clear, is then a blocking means 21 of the blocking element 20 against a locking lug 11 of the mass balance element 10 and thus prevents the mass balance element 10 passes back into the unlocking position 10a.

The mass balance element 10 has an actuating lever 13 which can communicate with the door handle 110 via a transmission element 14 in the form of a rocker. The transmission element 14 is in the FIGS. 2a to 4 not shown, it is schematic in the FIG. 1 indicated. The mass balance element 10 and the actuating lever 13 are firmly connected. Normally, the actuating lever 13 and the transmission element 14 serve to transmit the tensile force from the door handle 110 to the mass balance element 10 for opening the door, and at Accelerations to prevent adjustment of the mass balance element 10 in the unlocked position 10a.

The mass balance element is rotatable about an axis 12 and the locking element is rotatably supported about an axis 22, wherein the axes 12 and 22 are spaced apart and parallel. Such storage serves to pivot the mass balance element 10 and the blocking element 20 in accelerations I and II in the same directions of rotation S or E without hindering each other. At the same time, such an arrangement serves to allow the pivotable movement of the mass balance element 10 from the unlocking position 10a into the locking position 10b parallel and undisturbed by the pivotable movement of the blocking element 20 from the rest position 20a into the blocking position 20b. The movements which occur at accelerations I, which can act on the door handle 110 in the door opening unlocking position 110a, are in the FIGS. 2a and 4 indicated with the direction of rotation S. The movements that occur at opposite accelerations II, which can act on the door handle 110 in the door closing locking position 110b, are according to FIGS. 2b and 4 prevented. Although the mass balance element 10 can swing back undisturbed into its unlocking position 10a and the blocking element 20 in its rest position, but there is no danger that the door handle 110 is pivoted outwardly into the unlocking position 110a.

The above explanation of the embodiment describes the present invention solely by way of examples. Of course, individual features of the embodiment, if technically feasible, can be further developed without departing from the scope of the present invention as defined by the appended claims.
