Description

Vehicle seat with latch assembly

Technical Field

The present invention relates to a vehicle seat.

Background

The vehicle seat has a first component and a second component. The first and second members are movable relative to each other. The vehicle seat also has a latch assembly. The latch assembly has a latch element disposed on the first member and a rotary latch disposed on the second member. The locking element has a locking section for locking with the rotary latch.

Such latch assemblies are well known for locking various movable furniture of a vehicle seat. For example, such latch assemblies are used to lock adjustment devices for assisted (easy entry) boarding. They serve to prevent accidental operation of the movable installation, which may be triggered, for example, in the event of a crash.

In order to provide sufficient stability to absorb the undue forces that may occur in the event of a crash, the latching assemblies and in particular the latching elements have generally been constructed to be very strong.

It is disadvantageous here that the latching assembly and in particular the latching element require relatively large amounts of installation space and material.

Disclosure of Invention

The object of the invention is to provide a vehicle seat which can save installation space and material.

This object is achieved in particular by means of a vehicle seat according to the invention.

In addition to the latching section, at least one additional section for the bearing point of the functional element is therefore also provided on the latching element. The latching assembly can thus be used to provide at least one support point for the functional element. This saves the structural space required for providing at least one support point at different locations. Furthermore, since the latching assembly provides at least one bearing point, additional parts can be omitted, thereby saving material.

The locking element can have at least two functions, namely providing a locking section for rotating the latch and providing 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 in one piece on the latching element.

The at least one additional section may form a support for a functional element of the vehicle seat. In one embodiment, the functional element is articulated to at least one additional section. The at least one additional section may also have a support element on which the functional element is supported. The support element may be, for example, a rotating sleeve. The functional element may enclose a 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, at least one additional section can directly adjoin the latching section. Between the at least one additional section and the locking section, a section for the holding part of the adjusting element can optionally be arranged. The installation space in the region of the locking element 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 each other. The latching section and the at least one additional section can be oriented in 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 embodied in the form of a cylinder. The at least one additional section and the latching section can each be configured 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 flexibly take advantage of the installation space. Basically, at least one additional section can be adapted to the requirements of the installation space. In one embodiment, the latching element has two additional sections, which can be arranged, for example, at the ends of the latching element opposite to one another.

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 part may be fixed to the first part when the locking element is locked with the rotary latch. The locking element can then block the movement of the rotary latch together with the second part in a direction away from the first part, 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. For latching the second part to the first part, 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 encloses the latching element at least in the direction of the opening of the receptacle, so that the latching element can be fastened together with the rotary latch at the receptacle.

The second part can be limited in terms of its mobility relative to the first part in that the second part is locked to the locking element via the receptacle and the pivoting latch. By pivoting the latch, the direction in which the receptacle opens can be released, so that the receptacle can be released from the catch 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 guiding 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 guiding means may be, for example, an upper rail arranged on the seat part such that the seat part can be moved longitudinally along the lower rail by means of the upper rail. The catch element may be arranged on the upper rail.

In one embodiment, the functional element cooperates with the adjusting device. The adjusting device may be arranged for adjusting the vehicle seat. For example, the adjusting means may be provided for adjusting the catch assembly, in particular the rotary catch, or for adjusting the second guide means relative to the first guide means. Likewise, the adjusting means 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 activates the adjusting device, serves 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 latching assembly which can be actuated by means of a functional element. In addition to the latching assembly with latching elements and rotary latch, further latching assemblies can be provided. By means of the functional element, the further latching assembly can be adjustable between a latched and an unlatched state.

The further latching assembly may be designed to latch the first and second guide means to each other in order to lock the first and second guide means to each other in a movable manner. In the locked state of the further locking 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 cooperates with the seat longitudinal adjustment. The seat longitudinal adjustment may be configured for longitudinally adjusting the vehicle seat along a longitudinal vehicle axis. In particular, the seat longitudinal adjustment can be lockable with a further locking assembly. In one embodiment, the adjustment device has a seat longitudinal adjustment. Thus, the adjusting device may be provided for longitudinal adjustment of the vehicle seat.

In one embodiment, the second part is pivotable relative to the first part by means of an adjustment 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 to the first part. The first part can in particular be pivotable on the first part about a pivot axis. The second part may be pivotable from a first position in which the second part is arranged in a plane parallel to the first part into a second position. In the second positioning, the second part may be arranged at an angle of between 10 ° and 90 °, in particular between 20 ° and 45 °, to the first part. In embodiments where the second component has a seat portion and/or a backrest, the adjustment means may provide for boarding assistance. The seat part and/or the backrest can be adjusted by means of an adjusting device from the following regions: through which the person enters the vehicle and in which the vehicle seat is arranged in a defined manner. The vehicle seat may in particular be a driver seat or a co-driver seat. For example, the driver's seat is turned 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 adjustment device may comprise, for example, a handle or a drive on the backrest in addition to the pivot axis in order to pivot the second part relative to the first part.

In one embodiment, the functional element is designed to unlock the locking assembly. In particular, the functional element can shift the latching assembly from the latched state into the unlatched state. For example, the rotary latch may comprise an actuating pin, on which the functional element acts for unlocking the latching assembly.

In a further embodiment, the adjusting device comprises a locking element for locking the rotary latch. The locking element may 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 may 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 released accidentally from the adjusting element in the event of a crash. In general, the rotary latch may be subjected to an opening moment, for example, due to an improper force, as a result of which the rotary latch may be released from the adjusting element. The locking element ensures that the locking state of the rotary latch is protected from such incorrect forces. 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 locking element, with which first functional element the first adjusting device can be actuated. For example, the latch assembly may be unlocked using the first functional element. A second functional element with which the second adjusting device can be actuated can be provided on the second additional section of the locking element. For example, the further latching assembly, in particular the seat longitudinal adjustment, can be actuable with the second functional element.

In one embodiment, the functional element is provided for supporting the adjusting device when the second part is pivoted relative to the first part. In addition to the first and/or second functional elements for actuating the first and second adjusting means, functional elements provided for supporting the adjusting means may optionally be provided. The adjusting element may 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 may be introducible into the second part via the functional element, thereby pivoting the second part relative to the first part. For example, the regulating force may be generated by expansion of the 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, in the event of a crash, the functional element can provide an additional locking of the first and second guide means. An additional latching between the first and the second guide means can be triggered by the displacement of the functional element. The latching between the first and the second guide means can be in particular form-locking.

The functional element may be configured for embedding into a undercut on the first guide means. In particular, a recess can be provided on the undercut, which recess is designed for the functional element to be inserted therein. The functional element can be configured in the form of a hook in cross section for supporting the insertion into the undercut. In particular, the functional element may comprise a hook tip which is configured for insertion into the first guide means. The functional element may further comprise a hook side, with which the functional element is supported, if appropriate, in a rotatable manner, on at least one additional section. In one embodiment, the functional element may be configured as a J-hook or a retaining 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 in a form-locking manner via the functional element. Teeth or serrations may be formed on the functional element, in particular in the region of the hook tip, which teeth or serrations are provided for engagement in recesses of the undercut in the event of a crash. By the cooperation of the tooth and the recess, a strong, form-locking connection with the first guide means can be achieved in the event of a crash.

In principle, the functional element can be rotatably mounted on at least one additional section. 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, which each provide a bearing point for the functional element. The first functional element may be provided for actuating a first adjusting device, for example a seat longitudinal adjustment. The second functional element may be provided for actuating a second adjusting device, for example a latching assembly. The third functional element may be provided for supporting a third adjustment means, for example an adjustment means for pivoting the second part relative to the first part. The fourth functional element and optionally the fifth functional element may be displaceable in the event of a crash.

Detailed Description

Fig. 1 shows an embodiment of a vehicle seat F with a first component 1 arranged on the vehicle floor and a second component 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 fixedly arranged 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 and 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 part 1 via the holding portion 10. The holding portion 10 is formed in a U-shape. The holding portion has two symmetrical side portions 102, 103 which are connected to each other via a connection 101. The latching element 31 is supported on symmetrical side portions 102, 103. In particular, the catch element 31 can be arranged on the first part 1 in a manner rotatable about the longitudinal axis.

The rotary latch 32 can be arranged on the second part 2 in a rotatable manner relative to the second part 2 via a bearing pin 322, which is not shown here. By rotating the rotary latch 32 relative to the second part 2, the rotary latch 32 can be transferred from the illustrated latching position in which it latches with the latching element 31 into the unlocking position in which the rotary latch 32 does not latch with 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. Notch 321 circumferentially encloses latch section 310 from three sides. In the fourth-side direction, the latching section 310 can be moved out of 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 rotatably mounted on the locking element 31 relative to the locking element 31. Likewise, the functional element 4 can be connected to the locking element 31 in a rotationally fixed manner. In particular in this case, the catch element 31 can be arranged rotatably on the first part 1.

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

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

A locking element 31 is arranged on the second guide means 12, which has a locking section 310 for locking with the rotary latch 32. The catch element 31 is fastened to the second guide means 12 via the tongue-shaped side portions 102, 103 of the holding portion 10. The latch section 310 is arranged between the side portions 102, 103.

In addition to the latching section 310, the latching element 31 also comprises an additional section 311. The additional section 311 is configured as an axial extension which is integrally connected to the latching section 310. Further, an additional section 311 protrudes from the holding portion 10. In particular, the additional section 311 here protrudes from one of the side parts 102, 103. In the defined state, which is arranged on the vehicle seat F, the additional section 311 extends in the direction of the center of the vehicle seat F.

The seat longitudinal adjustment 6 shown has a further latching assembly 5 in addition to the latching element 31 which can be part of the latching assembly 3 together with the 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 being moved undesirably on the first guide means 11, for example, due to acceleration or braking of the vehicle on which the vehicle seat F may be arranged. In the locked state, the second guide means 12 cannot move 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 provided with the seat length adjustment portion 6 can then adjust the positioning of the vehicle seat F relative to the vehicle floor.

In order to operate the seat longitudinal adjustment 6 by a user, it may be necessary to enable the further latch assembly 5 to be operated by the user. For actuating the further catch assembly 5, a functional element 4 is provided. In the present case, the functional element 4 is embodied as an actuating arm. By actuating the further latching assembly 5 via the functional element 4, the further latching assembly 5 can be adjusted between the latched and unlatched state.

The functional element 4 is supported on the additional section 311 of the locking element 31. For example, the functional element 4 can be supported on the additional section 311 via a sleeve which 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 a further latching assembly 5 when the functional element 4 is lowered. For this purpose, a return element, such as a spring, may be provided on the actuating element 51.

In the embodiment shown in fig. 2B, a variant of the seat longitudinal adjustment 6 illustrated in connection with fig. 2A is shown. The first component 1 here comprises two pairs of first and second guide 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 one respective catch element 31. The latching elements 31 are arranged on the second guide means 12 mirror-symmetrically to each other 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 extend toward one another. The additional section 311 extends into the intermediate space between the two pairs.

The functional elements 4 are supported with one end in each case on the additional section 311. The functional element basically comprises three sections. The two sections extend along the first and second guide 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 simultaneously unlocks the two pairs of latching assemblies 3 when pivoted, so that the two pairs of second guide means 12 can each be moved relative to the first guide means 11.

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

The rotary latch 32 is mounted on the second part 2 in a pivotable manner. In the locked state, the rotary latch 32 engages with the locking section 310. Pivoting allows the pivoting latch 32 to disengage from the latch 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 back part R on which the user of the vehicle seat F can lean. The second part 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. a easy entry mechanism, which, when manipulated, pivots the seat part T and the backrest R of the vehicle seat so as not to obstruct the user of the vehicle in which the vehicle seat F is arranged. In particular, this may facilitate entry into the vehicle.

The catch element 31 is arranged on the U-shaped holding portion 10 on the first part 1. The U-shaped holding part 10 comprises two side parts 102, 103 on which the catch element 31 is supported. The latching section 310 is arranged outside the side sections 102, 103 on the seat part T side. Thus, the latching section 310 protrudes 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 lever which is pivotally mounted on the catch element 31. The functional element 4 can pivot 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 bearing 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. Yet another additional section 313 extends 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 a 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 part 1 latches with the second part 2. The locking element 33 can be actuated by means of the functional element 4 to release the locking of 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 actuating pin protrudes into a pivot region in which the functional element 4 can pivot. The locking latch is in the 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 rotary 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 part can pivot relative to the first part 1 about the swivel axis S. The rotary latch 32 can be disengaged from the catch element 31, for example, by pivoting the second part 2 relative to the first part 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 swivel 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 snapped into place with a snap-lock 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. At the present time, the rotary latch is disengaged from the catch element 31. The second part 2 is pivoted relative to the first part 1 by an angle of about 35. The rotary latch 32 is arranged pivotably on the second part 2 via a bearing pin 322.

The catch element 31 is arranged on the holding portion 10 on the first part 1. The holding portion 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 has an additional section 311, which forms a bearing point for the functional element 4. The latching section 310 and the additional section 311 are directly adjacent to one another.

The functional element 4 is used to support an adjustment device for adjusting the second part 2 relative to the first part 1. The functional element 4 is designed to introduce an adjusting force into the second part 2 in order to adjust the second part 2 relative to the first part 1. One end of the functional element 4 is hinged to the additional section 311. The other end of the functional element 4 is hinged to the second part 2. Thus, the functional element 4 mechanically connects the second part 2 with the first part 1. Furthermore, the functional element 4 can pivot relative to the first and second parts 1, 2. Thereby, the functional element 4 can accompany the swinging movement of the second part 2 relative to the first part 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 actuating force into the second component 2 by increasing the distance between the two ends, in particular supported by gas expansion or spring expansion.

The functional element 4 thus supports the oscillating movement of the second part 2 relative to the first part 1. The functional element 4 is currently a gas spring. For example, the functional element 4 may also have a spring or a screw drive.

Fig. 5A shows an embodiment in which the first component 1 has first guide means 11 which are provided for a secure connection with 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. In general, the second guide means 12 is moved longitudinally in the vehicle direction over the first guide means 11. For example, in the event of a crash, an undue force may occur which causes the second guide means 12 to loosen 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 improper 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 a defined operation of the vehicle seat F, the two functional elements 4 can be displaced along the first guide means 11 together with the second guide means 12. When an improper force is present that 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 and first guide means 11, 12. In particular in the event of a crash, the functional element 4 provides an additional locking of the first and second guide means 11, 12.

A recess 110 is provided on the first guide means 11. The recesses 110 are arranged in rows spaced apart from one another at intervals on the first guide means 11. The first guide means 11 has two rows of mutually parallel arranged recesses 110. The functional elements 4 each comprise an engagement means 41 which is designed as a toothing and which can engage with the recess 110 in the event of an incorrect force being present to displace the functional element 4. Since the recesses 110 are arranged in rows, it can be ensured that the recesses 110 into which the engagement means 41 can be inserted are always provided near the positioning of the functional element 4.

The second guide means 12 have a catch element 31. A locking section 310 for locking with the rotary lock 32 is provided on the locking element 31. In addition to the latching section 310, two additional sections 311, 312 are provided, which provide a bearing point 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 are arranged between the engagement means 41. The first guide means 11 are each provided 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 formed in the shape of a J or in the form of a holding angle. In particular, the functional element 4 may be a J-hook. The functional elements 4 are each fastened to one of the additional sections 311, 312 in the first section and each have an engagement means 41 in the second section. The first section is arranged in a plane parallel to the second section so that improper forces can be effectively absorbed.
