Description

Vehicle seat with latch assembly

Technical Field

The present invention relates to a vehicle seat according to the preamble of claim 1.

Background

Such a vehicle seat has a first part and a second part. The first and second parts are movable relative to each other. The vehicle seat also has a latch assembly. The latching assembly has a latching element arranged on the first part and a rotary latch arranged on the second part. The locking element has a locking section for locking with the rotary locking bar.

Such a latch assembly is well known for locking various movable facilities of a vehicle seat. For example, such a latch assembly is used to lock an adjustment device for boarding assistance (easy entry). They serve to prevent an accidental operation of the movable installation, which may be triggered, for example, in the event of a crash.

In order to provide sufficient stability for absorbing the forces which may occur in the event of a crash, the catch assembly and in particular the catch element are usually already of a robust design.

The disadvantage here is that the detent assembly and in particular the detent element requires a relatively large amount of installation space and material.

Disclosure of Invention

The object of the invention is to provide a vehicle seat which makes it possible to save on installation space and material.

This object is achieved in particular by a vehicle seat as claimed in claim 1.

In addition to the latching section, at least one additional section for a bearing point for the functional element is therefore provided on the latching element. The latching assembly can thus be used to provide at least one bearing point for the functional element. This saves the installation space required for providing at least one bearing point at different locations. Furthermore, since the latching assembly provides at least one bearing point, it is also possible to dispense with an additional part, as a result of which material is saved.

The latching element can have at least two functions, namely the provision of a latching section for rotating the latching bar and the provision of at least one additional section as a bearing point for the functional element. The latching section and the at least one additional section can be formed integrally on the latching element.

The at least one additional section can form a bearing point for a functional element of the vehicle seat. In one embodiment, the functional element is articulated to at least one additional section. At least one additional section can also have a support element on which the functional element is supported. The support element may be a rotating sleeve, for example. The functional element can enclose the jacket-shaped section of the at least one additional section.

In one embodiment, the at least one additional section is spaced apart from the latching section. The at least one additional section may be spaced apart from the latching section in the axial direction of the latching element. Likewise, the at least one additional section can directly adjoin the latching section. Between the at least one additional section and the latching section, a section for a holding section of the adjusting element can be arranged, if necessary. The installation space in the region of the latching elements can be flexibly designed for the arrangement of the functional elements.

In one embodiment, the latching section and the at least one additional section are aligned with one another. The latching section and the at least one additional section may be oriented along a common axial direction. The latching element may be a rotationally symmetrical component. In one embodiment, the latching element is a latch. In particular, the latching element can be formed in the form of a cylinder. The at least one additional section and the latching section can each be designed as a cylindrical section of the latching element. In one embodiment, the latching section and the at least one additional section are arranged offset from one another in order to utilize the installation space flexibly. Basically, the at least one additional section can be adapted as desired to the requirements of the installation space. In one embodiment, the latching element has two additional sections, which can be arranged, for example, at mutually opposite ends of the latching element.

In one embodiment, the rotary latch has a recess, in which the latching section is arranged when the latching element latches with the rotary latch. The second component can be fixed to the first component when the latching element latches with the rotary latch. The latching element can then block the movement of the rotary latch together with the second component in the direction away from the first component, in particular in the event of a crash.

In one embodiment, the second part has a receptacle which is open in the direction of the first part. In order to latch the second component on the first component, a latching element is arranged within the receptacle. In addition, the latching section can be arranged in a recess of the rotary latch, wherein the recess surrounds the latching element at least in the direction in which the receptacle is open, so that the latching element can be fixed together with the rotary latch at the receptacle.

The second part can be limited in terms of its mobility relative to the first part by the second part being fastened to the detent element via the receptacle and the rotary detent. By pivoting the latch, the direction in which the receptacle is open can be released, so that the receptacle can be released from the latching element when the second part is pivoted.

In one embodiment, the first component has a first guide means, which is provided for a secure connection to the vehicle floor. The first guide means may be, for example, a lower rail which can be fixed to the vehicle floor. Furthermore, the first component can have a second guide means, which is mounted on the first guide means in a movable manner. The second guide means may be, for example, an upper rail arranged on the seat part, so that the seat part can be moved longitudinally along the lower rail by means of the upper rail. The latching element can be arranged on the upper rail.

In one embodiment, the functional element interacts with the adjusting device. The adjustment device may be arranged for adjusting a vehicle seat. For example, the adjusting device can be provided for adjusting a latching assembly, in particular a rotary latch, or for adjusting the second guide means relative to the first guide means. Likewise, the adjustment device may be provided for adjusting a seat part and/or a backrest of the vehicle seat.

The functional element can cooperate with the adjusting device in such a way that the functional element triggers the adjusting device, is used to actuate the adjusting device, supports the adjusting device during adjustment, and/or provides a drive for the adjusting device.

In one embodiment, the adjusting device has a further detent assembly which can be actuated by means of the functional element. In addition to the latching assembly with the latching element and the rotary latch, a further latching assembly can be provided. By means of the functional element, the further locking assembly can be adjustable between a locked and an unlocked state.

The further latching assembly can be designed to latch the first and second guide means with respect to one another in order to lock the first and second guide means with respect to one another in a displaceable manner. In the latched state of the further latching assembly, the first and second guide means are therefore no longer movable relative to one another. In the unlocked state of the further latch assembly, the first and second guide means may be movable relative to each other.

In one embodiment, the functional element interacts with the longitudinal seat adjustment. The seat longitudinal adjustment portion may be configured for longitudinal adjustment of the vehicle seat along a longitudinal vehicle axis. In particular, the seat longitudinal adjustment can be latched by means of a further latching assembly. In one embodiment, the adjustment device has a seat longitudinal adjustment. Thus, the adjustment device may be arranged for longitudinal adjustment of the vehicle seat.

In one embodiment, the second part can be pivoted relative to the first part by means of the adjusting device. According to this embodiment, the second part can be pivoted relative to the first part by means of the adjusting device. For this purpose, the second part can be pivotably articulated on the first part. The first part can be pivotable on the first part, in particular about a pivot axis. The second component may be pivotable from a first orientation (in which the second component is arranged in a plane parallel to the first component) into a second orientation. In the second position, the second component can be arranged at an angle of between 10 ° and 90 °, in particular at an angle of between 20 ° and 45 °, to the first component. In embodiments where the second member has a seat portion and/or a backrest, the adjustment means may provide a boarding aid. The seat part and/or the backrest can be adjusted by means of the adjusting device from the following regions: through which a person enters the vehicle and in which vehicle seats are arranged in conformity with regulations. The vehicle seat may in particular be a driver seat or a co-driver seat. For example, the driver's seat is turned over in the direction of the steering wheel of the vehicle by means of an adjusting device, so that a person can comfortably enter into the front of the vehicle. The adjusting device can, for example, comprise, in addition to the pivot axis, a handle or a drive on the backrest for pivoting the second part relative to the first part.

In one embodiment, the functional element is designed to unlock the latching assembly. In particular, the functional element can bring the detent assembly into the unlocked state from the detent state. For example, the rotary latch can comprise, for example, an actuating pin on which a functional element acts for unlocking the catch assembly.

In a further embodiment, the adjusting device comprises a locking element for locking the rotary latch. The locking element can be adjustable with the functional element between a locked position in which the rotary latch is locked and an unlocked position in which the rotary latch is unlocked. The locking element can be adjustable via the functional element between a first position in which the rotary latch is locked and a second position in which the rotary latch is unlocked. The locking element prevents the rotary latch from being accidentally released from the adjusting element in the event of a crash. In general, the rotary latch may be subjected to an opening torque, for example, by an undue force, as a result of which the rotary latch may become disengaged from the adjusting element. The locking element ensures that the latching state of the rotary latch is protected against such an undesired force. The locking element may comprise an actuating pin on which the functional element acts to adjust the locking element.

In one embodiment, a first functional element is provided on the first additional section of the detent element, with which first adjustment device can be actuated. For example, the latch assembly may be unlockable using the first functional element. A second functional element can be provided on the second additional section of the locking element, with which second adjustment device can be actuated. For example, the additional latching assembly, in particular the seat longitudinal adjustment, can be actuated by means of the second functional element.

In one embodiment, the functional element is provided for supporting the adjusting device when the second component is pivoted relative to the first component. In addition to the first and/or second functional element for actuating the first and second adjusting device, a functional element provided for supporting the adjusting device can optionally be provided. The adjusting element can therefore comprise at least two or at least three additional sections for the bearing points for the functional element.

The functional element can support the adjusting device when the second part is pivoted in such a way that the functional element generates an adjusting force that supports the pivoting movement. The adjusting force can be introduced into the second component via the functional element, so that the second component is pivoted relative to the first component. The adjusting force can be generated, for example, by the expansion of a gas. In one embodiment, the functional element is a gas spring.

In a further embodiment, the functional element is displaceable. In particular, the functional element is displaceable in the event of a crash. In embodiments where the first component comprises first and second guide means, the functional element may be configured to prevent disengagement of the second guide means from the first guide means by displacement. For this purpose, the functional element can provide an additional latching of the first and second guide means in the event of a crash. An additional latching between the first and second guide means can be triggered by a displacement of the functional element. The latching between the first and second guide means can be in particular form-locking.

The functional element may be configured for embedding into an undercut on the first guiding means. In particular, a recess can be provided on the undercut, which recess is designed to insert a functional element therein. The functional element may be designed in a hook-shaped manner in cross section for supporting the insertion into the undercut. In particular, the functional element may comprise a hook tip, which is designed to engage in the first guide means. The functional element can furthermore comprise a hook side with which the functional element is supported on the at least one additional section in a rotatable manner, if appropriate. In one embodiment, the functional element may be configured as a J-hook or a retention angle.

In one embodiment, the functional element is designed to engage with the first guide means in the event of a crash, so that the second guide means is connected to the first guide means via the functional element in a form-fitting manner. A toothing or a serration can be formed on the functional element, in particular in the region of the hook point, which is provided for engaging in a recess of the undercut in the event of a crash. By means of the interaction of the toothing and the recess, a strong, form-locking connection to the first guide means can be achieved in the event of a crash.

In principle, the functional element can be mounted on the at least one additional section in a rotatable manner. In embodiments with displaceable functional elements, the functional elements may be fixed in a certain orientation.

In one embodiment, at least four or at least five additional sections are provided on the latching section, each of which provides a bearing point for the functional element. The first functional element can be provided for actuating a first adjusting device, for example a longitudinal seat adjusting part. The second functional element can be provided for actuating a second adjusting device, for example a catch assembly. The third functional element may be provided for supporting a third adjusting device, for example an adjusting device for pivoting the second component relative to the first component. The fourth functional element and, if appropriate, the fifth functional element can be displaceable in the event of a crash.

Detailed Description

Fig. 1 shows an embodiment of a vehicle seat F with a first part 1 arranged on the vehicle floor and a second part 2 comprising a seat part T and a backrest R of the vehicle seat F. The first component may be movable relative to the vehicle floor or arranged fixedly on the vehicle floor relative to the floor. The first and

second parts

1, 2 are movable relative to each other. In the embodiment shown, the second part 2 is pivotable relative to the first part 1 in such a way that the seat part T and the backrest R are pivoted in the direction of arrow E.

The vehicle seat F has a latch assembly 3 with a latch element 31 and a rotary latch 32. The catch element 31 is arranged on the first part 1, while the rotary catch 32 is arranged on the second part 2. Furthermore, the locking element 31 has a locking section 310 for locking with the rotary latch 32. In the illustrated embodiment, the rotary latch 32 latches with the latching section 310.

The catch element 31 is arranged on the first component 1 via the holding part 10. The holding part 10 is U-shaped. The holding part has two

symmetrical side parts

102, 103, which are connected to each other via a connection 101. The latching elements 31 are supported on

symmetrical side parts

102, 103. In particular, the locking element 31 can be arranged on the first component 1 so as to be rotatable about a longitudinal axis.

The rotary latch 32 can be arranged on the second part 2 so as to be rotatable relative to the second part 2 via a bearing pin 322, not shown here. By rotating the rotary latch 32 relative to the second part 2, the rotary latch 32 can be moved from the illustrated latched position, in which it is latched to the latching element 31, into an unlatched position, in which the rotary latch 32 is not latched to the latching element 31. The rotary latch 32 has a recess 321 in which a section of the latching section 310 is arranged in the latching position. Notches 321 circumferentially surround snap-lock section 310 from three sides. In the direction of the fourth side, the latching section 310 can be removed from the recess 321.

In addition to the latching section 310, an additional section 311 is provided on the latching element 31. The additional section 311 has a bearing point for the functional element 4. The functional element 4 can be mounted on the latching element 31 so as to be rotatable relative to the latching element 31. Likewise, the functional element 4 can be connected to the detent element 31 in a rotationally fixed manner. In particular, the catch element 31 can be arranged on the first component 1 in a rotatable manner in this case.

The functional element 4 has a bearing section 40, via which the functional element 4 is supported on a bearing point. In the present case, the bearing section 40 is snapped onto one end of the latching element 31 from the axial direction of the latching element 31. Alternatively, the bearing section 40 can act on the additional section 311 from the radial direction.

Fig. 2A and 2B each show an embodiment of the seat longitudinal adjusting portion 6. For the longitudinal adjustment of the vehicle seat F, the first component 1 comprises first guide means 11, which can be connected to the vehicle floor. The first guide means 11 now comprise a lower rail. Furthermore, the first component 1 comprises second guide means 12, which are adjustable relative to the first guide means 11. The second guiding means 12 currently comprises an upper rail. The upper rail is movably supported in the lower rail. In the state of being installed in the vehicle in a proper manner, the second guide means 12 can be moved relative to the first guide means 11 in the longitudinal direction of the vehicle.

A latching element 31 is arranged on the second guide means 12, said element having a latching section 310 for latching with the rotary latch 32. The catch element 31 is fixed to the second guide means 12 via the tongue-shaped

lateral sections

102, 103 of the holding part 10. The latch section 310 is arranged between the

side parts

102, 103.

In addition to the latching section 310, the latching element 31 also comprises an additional section 311. The additional section 311 is designed as an axial extension integrally connected to the latching section 310. Furthermore, an additional section 311 protrudes from the holding portion 10. In particular, the additional portion 311 projects here from one of the

side parts

102, 103, the side part 103. In a state of being arranged on the vehicle seat F in conformity with the specification, the additional section 311 is extended toward the center of the vehicle seat F.

The illustrated seat longitudinal adjustment 6 has a further latching assembly 5 in addition to a latching element 31 which can be part of the latching assembly 3 together with a rotary latch 32. The further latching assembly 5 is designed to latch the first and second guide means 11, 12 to one another. It is thereby possible to prevent the second guide means 12 from undesirably moving on the first guide means 11, for example due to acceleration or braking of a vehicle on which the vehicle seat F may be arranged. In the latched state, the second guide means 12 cannot be moved relative to the first guide means 11. When the further latch assembly 5 is unlocked, the second guide means 12 can be moved relative to the first guide means 11. The user of the vehicle seat F, in which the seat length adjusting portion 6 is arranged, can then adjust the positioning of the vehicle seat F with respect to the vehicle floor.

In order to operate the seat longitudinal adjustment 6 by the user, it may be necessary for the additional latch assembly 5 to be able to be actuated by the user. For actuating the further detent assembly 5, a functional element 4 is provided. In the present case, the functional element 4 is designed as an actuating arm. By actuating the further latch assembly 5 via the functional element 4, the further latch assembly 5 can be adjusted between the latched and unlatched state.

The functional element 4 is supported on the additional section 311 of the latching element 31. For example, the functional element 4 can be mounted on the additional section 311 via a sleeve that can be rotated relative to the additional section 311. The functional element 4 can pivot about the additional section 311 when actuated. The functional element is designed to actuate the actuating element 51 of the further latch assembly 5 when actuated, so that the further latch assembly 5 is unlocked. In this case, the functional element 4 lifts the actuating element 51 in order to unlock the further locking assembly 5. The functional element 4 can lower the actuating element 51 in order to latch a further latching assembly 5. In the present case, the actuating element 51 is designed to automatically latch the further latching assembly 5 when the functional element 4 is lowered. For this purpose, a restoring element, such as a spring, can be provided on the actuating element 51.

In the exemplary embodiment shown in fig. 2B, a variant of the seat longitudinal adjustment 6 explained in conjunction with fig. 2A is shown. The first part 1 here comprises two pairs of first and second guiding means 11, 12. The two pairs are arranged parallel to each other and spaced apart from each other via an intermediate space. The second guide means 11, 12 comprise in each case one latching element 31. The latching elements 31 are arranged on the second guide means 12 mirror-symmetrically to one another with respect to the axis of symmetry between the pairs of guide means 11, 12. This means in particular that the additional sections 311 of the locking element 31 are arranged so as to project toward one another. The additional section 311 projects into the intermediate space between the two pairs.

The functional elements 4 are each supported at one end on the additional section 311. The functional element basically comprises three segments. The two sections extend along the first and second guiding means 11, 12, respectively. The third section extends through the intermediate space in order to connect the two sections. The functional element 4 can be actuated by means of the third section.

When the functional element 4 is actuated, the functional element 4 pivots about the two additional sections 311 and, when pivoting, simultaneously unlocks the two pairs of detent assemblies 3, so that the two pairs of second guide means 12 can be moved relative to the first guide means 11, respectively.

Fig. 3 shows an embodiment in which the second part 2 is pivotable relative to the first part 1. The second part 2 is mounted on the first part 1 so as to be pivotable about a pivot axis S. The catch element 31 is arranged on the first part 1 and the rotary catch 32 on the second part 2. The latching element 31 has a latching section 310 for latching with the rotary latch 32. When the rotary latch 32 latches with the latching section 310, the second component 2 cannot pivot relative to the first component 1. When the latching of the rotary latch 32 with the latching section 310 is released, the second component 2 can pivot relative to the first component 1.

The rotary latch 32 is pivotably supported on the second part 2. In the latched state, the rotary latch 32 engages with the latching section 310. Pivoting allows the rotary latch 32 to disengage from the latching section 310. When the rotary latch 32 is disengaged from the latching section 310, the second part 2 can pivot relative to the first part 1.

In the present case, the second part 2 comprises a seat part T, on which a user of the vehicle seat F can sit, and a backrest part R, on which the user of the vehicle seat F can lean. The second component 2 comprises a floor adapter B via which the vehicle seat can be fastened to the vehicle floor. The pivoting of the second part 2 relative to the first part 1 can be used for boarding assistance, i.e. an easy entry mechanism, upon actuation of which the seat part T and the backrest R of the vehicle seat are pivoted so as not to obstruct the user of the vehicle in which the vehicle seat F is arranged. In particular, this may make it easy to enter the vehicle.

The latching element 31 is arranged on the U-shaped holding section 10 on the first component 1. The U-shaped holding part 10 comprises two

side parts

102, 103, on which the latching element 31 is supported. The latching section 310 is arranged outside the

side parts

102, 103 on the seat part T side. Thus, the latching section 310 projects beyond the holding part 10. The rotary latch 32 latches with the latching section 310.

In addition to the latching section 310, an additional section 311 is provided. The additional section 311 is arranged between the two

side portions

102, 103 of the holding portion 10. The additional section 311 forms a bearing point for the functional element 4. The functional element 4 is configured as a control lever which is pivotably supported on the latching element 31. The functional element 4 can be pivoted about the latching element 31. Alternatively, the functional element 4 can be connected in a rotationally fixed manner to the latching element 31, wherein the latching element 31 is rotatably mounted on the holding part 10, so that the latching element 31 rotates in a mounting on the holding part 10 when the functional element 4 is pivoted.

The locking element 31 has a further additional section 312, on which a further functional element 4 can be arranged. A further additional section 313 projects beyond the holding part 10 at the end of the latching element 31 remote from the latching section 310. For example, a further functional element 4 can still be provided on the further additional section 313.

For example, a functional element 4 for actuating the seat longitudinal adjustment 6 can be provided on one of the further

additional sections

312, 313.

In addition to the rotary latch 32, a locking element 33 is provided on the second part 2. The rotary latch 32 can be locked by means of the locking element 33. When the rotary latch 32 is locked with the locking element 33, the rotary latch 32 is fixed in a latching position in which the first component 1 latches with the second component 2. The locking element 33 can be actuated by means of the functional element 4 in order to release the rotary latch 32. Upon actuation by the functional element 4, the locking element 33 is adjusted between a locking position (in which the rotary latch 32 is locked) and an unlocking position (in which the rotary latch 32 is unlocked).

In the present case, for actuation by the functional element 4, an actuating pin 34 is provided on the locking element 33, which pin projects into a pivot region in which the functional element 4 can pivot. The locking latch is in a locked position. By pivoting the functional element 4, the actuating pin 34 can be actuated and thus the locking latch can be adjusted into an unlocking position in which the rotating latch 32 is unlocked.

When the rotary latch 32 is unlocked, the rotary latch 32 can be disengaged from the catch element 31, so that the second component can be pivoted relative to the first component 1 about the pivot axis S. The rotary latch 32 can be disengaged from the catch element 31, for example, by pivoting the second component 2 relative to the first component 1 when the locking element 33 is in the unlocking position.

Fig. 4 shows an embodiment in which the first part 1 is pivotable relative to the second part 2. The second part 2 is pivotable about a pivot axis S, at which the second part 2 is supported on the first part 1.

A rotary latch 32 is arranged on the second part 2, which can be latched with a latching element 31 arranged on the first part 1. The rotary latch 32 has a recess 321 which can engage with the latching section 310 of the latching element 31. In the present case, the rotary latch is disengaged from the catch element 31. The second part 2 is pivoted by an angle of about 35 deg. relative to the first part 1. The rotary latch 32 is arranged pivotably on the second part 2 via a bearing pin 322.

The latching element 31 is arranged on the holding section 10 on the first component 1. The retaining part 10 is configured as a wall section on the first component 1. The latching element 31 projects in a direction away from the center of the vehicle seat F.

In addition to the latching section 310, the latching element 31 also has an additional section 311, which forms a bearing point for the functional element 4. The latching section 310 and the additional section 311 directly adjoin one another.

The functional element 4 is used to support an adjustment device for adjusting the second component 2 relative to the first component 1. The functional element 4 is designed to introduce an adjusting force into the second component 2 for adjusting the second component 2 relative to the first component 1. One end of the functional element 4 is hinged to the attachment section 311. The other end of the functional element 4 is hinged to the second part 2. The functional element 4 thus mechanically connects the second component 2 with the first component 1. Furthermore, the functional element 4 can be pivoted relative to the first and

second components

1, 2. The functional element 4 can thereby be accompanied by a pivoting movement of the second component 2 relative to the first component 1.

The length of the functional element 4 is variable in a manner dependent on the magnitude of the pivoting movement of the second part 2 relative to the first part 1. The greater the adjustment movement, the greater the length of the functional element 4. The length of the functional element 4 is defined here by the distance between the two ends of the functional element 4. The functional element 4 is designed to introduce an adjusting force into the second component 2 by an increase in the distance between the two ends, which is supported in particular by a gas or spring expansion.

The functional element 4 thus supports the pivoting movement of the second component 2 relative to the first component 1. In the present case, the functional element 4 is a gas spring. For example, the functional element 4 can also have a spring or a spindle drive.

Fig. 5A shows an embodiment in which the first component 1 has a first guide means 11 which is provided for a secure connection to the vehicle floor. Furthermore, the first component 1 has a second guide means 12, which is mounted on the first guide means 11 in a movable manner. Normally, the second guide means 12 is moved longitudinally on the first guide means 11 in the direction of the vehicle. For example, in the event of a crash, an undue force may occur which causes the second guide means 12 to release from the first guide means 11 transversely to the vehicle direction.

In order to prevent the second guide means 12 from being released from the first guide means 11 in the event of an incorrect force, two functional elements 4 are provided on the second guide means 12, which are displaced together with the second guide means 12 in the event of a crash. In the normal case, i.e. in the case of a proper operation of the vehicle seat F, the two functional elements 4 can be moved together with the second guide means 12 along the first guide means 11. When an incorrect force occurs, which displaces the second guide means 12 together with the two functional elements 4, the functional elements 4 latch with the first guide means 11, so that the second guide means 12 cannot be released from the first guide means 11. The functional element 4 forms a form-locking connection with the first guide means 11 for latching the second guide means 11, 12. The functional element 4 provides an additional latching of the first and second guide means 11, 12, in particular in the event of a crash.

A recess 110 is provided on the first guide means 11. The recesses 110 are arranged in rows spaced apart from one another on the first guide means 11. The first guiding means 11 has two rows of recesses 110 arranged parallel to each other. The functional elements 4 each comprise an engagement means 41 which is designed as a toothing and which can be brought into engagement with the recess 110 in the event of a displacement of the functional elements 4 due to an incorrect force. Since the recesses 110 are arranged in rows, it can be ensured that, in the vicinity of the location of the functional element 4, there is always provided a recess 110 into which the engagement means 41 can engage.

The second guide means 12 has a latching element 31. A locking section 310 for locking with the rotary latch 32 is provided on the locking element 31. In addition to the latching section 310, two

additional sections

311, 312 are provided, which provide bearing points for the functional element 4. Two

additional sections

311, 312 are shown in the embodiment in fig. 5B.

One of the functional elements 4 is arranged on each of the

additional sections

311, 312. The engagement means 41 of the functional element 4 are arranged symmetrically with respect to the first guide means 11. The first guide means 11 is arranged between the engagement means 41. The first guide means 11 are each formed with a undercut at the engagement means 41. The recess 110 is arranged at the undercut so that the engagement means 41 engage in a simple manner when the second guide means 12 is moved away from the first guide means 11. The functional element 4 is J-shaped or formed in the form of a retaining angle. In particular, the functional element 4 may be a J-hook. In the first section, the functional elements 4 are each fastened to one of the

additional sections

311, 312, and in the second section, the functional elements each have an engagement means 41. The first section is arranged in a plane parallel to the second section, so that undesired forces can be absorbed effectively.
