TRIM STRIP AND CONNECTOR FOR A CAR BODY

Description

Technical field

[0001] The present development concerns a decorative trim strip for a motor vehicle body and an associated motor vehicle. background

[0002] From DE 10 2013 223 358 B4, for example, a device for attaching a decorative strip to a vehicle exterior body element is known. An end section of a decorative strip body is provided with a bore into which a fastening pin of a respective end cap can be inserted in order to connect the end cap to the decorative strip element in a way that allows for at least frictional locking and releasable connection.

[0003] Furthermore, a decorative strip for a window glass of a vehicle is known from DE 603 ​​06 317 T2.

[0004] For a particularly simple, rational and cost-effective production of decorative strips for placement in or on the exterior of a motor vehicle body, it can be advantageous and desirable to design the decorative strip in multiple parts and to connect several strip sections together, for example by means of a plug connection, during assembly or before assembly on the motor vehicle.

[0005] The present development aims to provide a multi-part decorative strip with a plug-in connection that is particularly easy to assemble and, if necessary, also relatively easy to disassemble. Furthermore, the plug-in connection should be characterized by a high degree of mechanical stability and a long service life. It should be particularly suitable for use and installation on or in the exterior of a motor vehicle body.

[0006] The plug-in connection is also intended to allow for the direct attachment of multiple trim strip sections to the vehicle body, whereby the connection between the trim strip sections can occur either during or only after assembly on the vehicle body. In this respect, the objective is to simplify both the assembly process for manufacturing the trim strip and its attachment to the vehicle body. The objective is therefore to reduce the manufacturing and production costs of a vehicle. Advantageous designs

[0007] This problem is solved with a decorative trim and a motor vehicle according to the features of independent claim 1. Advantageous embodiments are the subject of dependent claims.

[0008] According to a first aspect of the present further development, a multi-part decorative strip with a plug-in connection is provided. The plug-in connection comprises an insertion part and a receiving part. The insertion part has a longitudinally extended insertion pin, which can be inserted longitudinally into a corresponding or complementary receptacle in the receiving part. The insertion pin has a top and an opposite bottom. The insertion pin also has two opposing outer surfaces, for example, a left outer surface and a right outer surface. The outer surfaces extend between the top and the bottom. They extend, in particular, along the side edges of the top and bottom. Thus, the top transitions into the bottom via the opposing outer surfaces; and vice versa.

[0009] The receptacle, corresponding to the mortise pin, has a top surface and two opposing side faces. Each side face has a projection facing away from the top surface. The projection of one side face extends to the opposite side face. The projection of the other side face also extends to the opposite side face. These projections of both side faces extend to their respective opposite sides. They are typically located at the end section of each side face facing away from the top surface.

[0010] At least one locking element is formed or arranged on the underside of the insertion pin. This locking element can be engaged with a corresponding counter-locking element to form a positive-locking connection between the insertion part and the receiving part. The counter-locking element is provided, formed, or arranged on at least one of the side faces or on at least one of the projections. The counter-locking element and the locking element can engage in a positive-locking manner to form a positive connection along the longitudinal direction of the insertion part and the receiving part. This connection can only be released by moving at least one of the locking element and counter-locking element into a disengaged position.

[0011] In a final assembly configuration on the vehicle, i.e., on the vehicle body, the underside of the insertion pin points towards the outside of the vehicle body. The top side of the receptacle is visible from the outside in the final assembly position on the vehicle body.

[0012] Viewed from the outside or from above, the top surface has a continuous surface that defines or shapes the external appearance of the multi-part decorative molding. The receptacle formed in or on the receiving part has a C-shaped profile in cross-section, with the top surface situated between the opposing side flanges. The projections on the side flanges can extend approximately or substantially parallel to the plane of the top surface. In a final assembly configuration, where the mortise pin is inserted into the receptacle, the side flanges, with their inwardly projecting projections, can, for example, circumferentially enclose or at least partially overlap the outer surfaces of the mortise pin.

[0013] In this way, particularly with a precisely fitting design of the receptacle and insertion pin, a sliding guide for the insertion pin can be provided, which is typically insertable longitudinally into the receptacle of the receiving part, and in particular can be inserted by sliding motion, until a final assembly position is reached in which the at least one locking element formed on or arranged on the insertion pin engages with the corresponding or complementary counter-locking element of the receptacle or receiving part. The mutual engagement of the locking element and counter-locking element results in a mutual fixing of the receiving part and insertion part with respect to the longitudinal direction of the receiving part and / or insertion part.

[0014] Because at least one locking element is located on the underside of the insertion pin, it can be designed to be accessible from below. This allows, for example, when a trim strip has been removed from the vehicle body, and the insertion part and the receiving part remain positively connected via the at least one locking element and the at least one counter-locking element, at least one of the locking element and counter-locking element can be manually moved from below by an end user or installer into a release position in which the locking element releases the counter-locking element; or vice versa. The insertion pin can then be pulled out of the receptacle in the opposite direction to its original installation. This ultimately enables non-destructive removal of the multi-part trim strip.

[0015] It is particularly advantageous if the counter-locking element is formed or arranged on at least one of the inwardly projecting extensions of the receptacle that project inwards from the side walls. This is because the inwardly projecting extensions of the receptacle can be easily accessible from below when the trim strip is removed. The elements that engage with each other in a locking manner—namely, the at least one locking element and the at least one counter-locking element—can be arranged or formed outside the externally visible surfaces of the insertion part and the receptacle, so that the manner of the mutual connection between the insertion part and the receptacle is not visible from the outside, even when the trim strip is mounted on the vehicle body.

[0016] In a further embodiment, the locking element has at least one spring tongue that is movable or deformable transversely or perpendicular to the longitudinal direction and has an end stop. The spring tongue is typically movably or deformably arranged on the insertion part between a locking position and a release position, or is integrally formed therein. During assembly, the spring tongue can slide along the mating locking element of the receptacle with a chamfered leading edge. Upon reaching a final assembly position, the spring tongue can spring into the locking position and engage with the mating locking element of the receptacle. In the final assembly position of the insertion part and receptacle, particularly when the spring tongue is in its locking position, the end stop rests against or is supported by a counter-stop of the mating locking element.The end stop and the counter stop are directly adjacent to each other in the longitudinal direction of the insertion part and the receiving part, so that the end stop is supported in the longitudinal direction against the counter stop; and vice versa.

[0017] In a further embodiment, the end stop has a stop surface with a surface normal that is oriented longitudinally opposite to the insertion direction of the insert into the receiving part. The end stop thus acts as a kind of barb. It is oriented opposite to the insertion direction into the receiving part and, provided it is in contact with the counter stop, prevents the insert pin from being pulled out of the receiving part's receptacle.

[0018] In a further embodiment, the counter-locking element has at least one recess extending transversely or perpendicularly to the longitudinal direction, with the aforementioned counter-stop. The recess typically extends either on the inside of a side wall or adjacent to an inner edge of one of the inwardly extending projections provided on the side walls. The counter-stop of the counter-locking element is typically designed or configured to correspond to or complement the end stop of the locking element. In this way, when the insertion part and receiving part reach their final assembly position, the end stop and the counter-stop can bear against each other in a longitudinally supportive manner, thus preventing or blocking the insertion part from sliding or being pulled out of the receiving part.

[0019] In a further embodiment, the counter-stop has a stop surface with a surface normal that is aligned longitudinally along the insertion direction of the insert part into the receiving part. The surface normal of the stop surface of the counter-stop extends opposite to the surface normal of the stop surface of the end stop. In this way, mutual and longitudinally acting support of the locking element and counter-locking element can be provided in the longitudinal direction of the insert part and / or receiving part.

[0020] Alternatively, the locking element can be arranged not on the insertion side but on the receptacle side, and the corresponding or complementary counter-locking element is not located on the receptacle but on the insertion side. In this respect, a quasi-kinematic reversal of the locking element and counter-locking element on the insertion and receptacle sides is also possible. It is also conceivable that the locking element and / or its movable or deformable spring tongue is located on the receptacle, particularly on a side wall or extension of the receptacle, and that the corresponding counter-locking element is located on the underside of the insertion pin.

[0021] According to the invention, at least one locking element is arranged recessed from the opposite outer surfaces of the insertion pin. The at least one counter-locking element is arranged or formed on an inner edge of the extension. The inner edge of the extension refers to the edge of the extension that faces away from the adjacent side wall. In a receptacle shaped approximately like a C-profile, for example, the side walls extend parallel to each other. At the ends of the side walls facing away from the upper surface, extensions face each other.

[0022] The facing inner surfaces of the projections form the aforementioned inner edges, on which at least one counter-locking element is arranged or formed. The counter-locking element can be embedded or recessed into an inner edge of one of the projections or into the inner edges of both projections. The recessed arrangement of the locking element relative to the outer surfaces is advantageous insofar as the locking element does not protrude from the outer surface of the insertion pin.

[0023] In this way, potential damage to a locking element that would otherwise protrude from the outside of the insertion pin can be effectively avoided. Furthermore, the locking element's concealed position reduces the risk of injury emanating from it. The internal arrangement of the locking element is also advantageous for a locking mechanism between the locking element and its counterpart that is not visible from the outside. Thus, the corresponding counterpart can be located or designed within an area of ​​the receptacle that is not visible from the outside.

[0024] In a further embodiment, the insertion pin has a base section that extends longitudinally via a central section into a head section. The head section forms a free end of the insertion pin. At least one locking element is also arranged on the head section and extends longitudinally into the central section of the insertion part. A free end of the locking element is typically located in the area of ​​the central section. A base or guide section of the locking element is typically arranged on the head section or formed integrally with, or molded onto, the head section.

[0025] The spring tongue therefore has a movable or deformable free end located in the area of ​​the central section. The end stop of the spring tongue is typically located at the free end of the spring tongue, which lies in the area of ​​the central section of the insertion pin. The end stop of the spring tongue can, in particular, point towards the base section of the insertion pin or be oriented towards the base section. In this way, a longitudinally directed, mutual support of the locking element and counter-locking element can be provided.

[0026] In a further embodiment, at least one web extending from the underside of the head section has a chamfer or bevel. The chamfer extends obliquely or perpendicularly to the plane of the underside of the insertion pin.

[0027] The ridge extending from the underside can protrude from the underside of the insertion pin. The ridge can taper towards the free end of the head section. This allows for particularly easy insertion of the insertion pin into the receptacle of the receiving part. The chamfered edge of the ridge allows for centering perpendicular or transverse to the longitudinal direction of the insertion and receiving parts.

[0028] In a further embodiment, at least one web can be brought into engagement with an inner edge of the extension formed on the side walls of the receptacle. Furthermore, or alternatively, it can be provided that the web can be brought into sliding engagement with a side of the extension of the side walls that faces the top of the receptacle.

[0029] If the bridge is typically brought into sliding engagement with an inner edge of the extension via an outer surface, centering can be achieved transversely or perpendicularly to the mounting direction, particularly in the transverse direction of the mount, by means of the bridge of the head section projecting downwards from the underside.

[0030] In a further embodiment, two approximately parallel webs, each with a chamfer, can be arranged or formed on the underside. A left web can, for example, be slidably engaged with the inner edge of a left extension of a left side wall of the receptacle, while a corresponding right web can be slidably engaged with the inner edge of a right extension of a right side wall. In this way, mutual centering of the insertion part and the receptacle can be provided transversely to the insertion direction, or transversely to the longitudinal direction of the insertion part and the receptacle.

[0031] In a further embodiment, the central section of the insertion pin has a longitudinally extending rib that stretches from the head section to the base section. This longitudinal rib stiffens or reinforces the insertion part, thereby increasing its mechanical structural rigidity. In another embodiment, recesses or even through-openings can be provided or formed along the sides of the longitudinal rib. This advantageously reduces the weight of the insertion part.

[0032] The longitudinally extended rib is typically located on the underside of the insert. Similar to at least one locking element, it can protrude from the underside of the insert and thus contribute to stiffening the insert.

[0033] In a further embodiment, the previously described web section in the area of ​​the base section has a web segment extending transversely or perpendicularly to the longitudinal direction, which, in the assembly position of the insertion and receiving parts, abuts the opposing inner surfaces or inner edges of the projections. In this way, the outer surfaces of the web segment extending, for example, transversely or perpendicularly to the longitudinal direction, can abut the inner surfaces of the projections in the transverse direction, thus providing mutual centering of the insertion and receiving parts in the transverse direction.

[0034] The web section extending transversely or perpendicularly to the longitudinal direction can be integrally connected to a longitudinally extending web section of the web. In particular, the web provided on or in the central section can have a T-shaped geometry or contour, which contributes on the one hand to a mechanical stiffening of the insertion part and on the other hand to a mutual centering of the insertion part and receiving part transversely or perpendicular to the insertion direction.

[0035] In a further embodiment, the upper surface of the insertion pin can be slidably engaged with the inner surface of the upper surface of the receptacle. Additionally or alternatively, the opposing outer surfaces of the insertion pin can be slidably engaged with the inner surfaces of the side walls of the receptacle of the receiving part. The upper surface of the insertion pin and the inner surface of the upper surface of the receptacle can be provided with corresponding sliding surfaces, enabling particularly easy sliding engagement of the insertion pin in the receptacle of the receiving part.

[0036] Similarly, the opposing outer surfaces of the insertion pin and the inner surfaces of the side walls can also be provided with corresponding sliding surfaces, typically designed to correspond or complement each other. In this way, particularly low joining forces can be achieved, so that the insertion pin can be inserted into the receptacle very easily, and ultimately, only very low assembly forces are required for the reciprocal assembly of the insertion part and the receptacle part.

[0037] In a further embodiment of the plug connection, a first locking element, as previously described, and a second locking element, designed symmetrically to it, are formed or arranged on the underside of the insertion pin. The first locking element can be engaged with a first counter-locking element on a side wall or its extension. The second locking element can be engaged with a second counter-locking element on an opposite side wall or its extension.

[0038] With respect to the longitudinal direction, the locking elements as well as the counter-locking elements can be arranged at the same height, so that a mirror-symmetrical design of the first and second locking element or of the first and second counter-locking element can be realized with respect to the central longitudinal axis of the insertion part and the receiver.

[0039] By means of first and second locking elements that engage with first and second counter-locking elements, a further improved mechanical connection between the receiving part and the insertion part can be achieved.

[0040] The decorative strip further comprises a first strip section and a second strip section. The first and second strip sections are adjacent to each other lengthwise and can be detachably connected by means of a previously described plug-in connection. The first strip section can, for example, function as a receiving part or be designed as the receiving part of the plug-in connection.

[0041] The second strip section can therefore function as an insertion part of the previously described connector or be designed as an insertion part of the connector itself. Furthermore, it is conceivable that a separate insertion part is arranged or attached to one longitudinal end of the second strip section and / or that a receiving part is arranged or attached to one longitudinal end of the first strip section.

[0042] The decorative strip is by no means limited to just two strip sections. Multiple plug connections can be provided for the first, second, and optionally also third and / or fourth strip sections, each of which can be connected to each other using a previously described plug connection, in order to provide a longitudinally extended decorative strip for installation on a motor vehicle body.

[0043] According to a further aspect, the present disclosure also relates to a motor vehicle with a motor vehicle body and with a previously described decorative trim. The decorative trim can, in particular, be designed as a roof-side decorative trim that extends, for example, from an A-pillar to a B-pillar and / or to a C-pillar and / or to a D-pillar of the motor vehicle body. Brief description of the characters

[0044] Further objectives, features, and advantageous embodiments of the present development are explained in the following description of an exemplary implementation. These will show: Fig. 1 a schematic side view of a motor vehicle, Fig. 2 a view of a trim strip from below in the area of ​​a plug connection, Fig. 3 a representation of the plug connection according to Fig. 2, however, in a pre-assembly configuration, Fig. 4 an isolated perspective view of an insert part, Fig. 5 another perspective view of the insert part, Fig. 6 another perspective view of the insert part, Fig. 7 another perspective view of the insert part viewed from above, Fig. 8 a perspective interior view of the receptacle for the receiving part, Fig. 9 another perspective view of the receptacle for the receiving part, Fig. 10 a top view of the insert part viewed from above, Fig. 11 another perspective view of the insert part viewed from an oblique angle above, Fig. 12 a perspective view of a multi-part decorative strip and Fig. 13 a perspective cross-section AA according to Fig. 12 . Detailed description

[0045] The in Fig. 1The schematically depicted motor vehicle 1 has a vehicle body 2 with an interior 3 functioning as a passenger compartment and a roof structure 4 extending above the interior 3. In the area of ​​the roof structure 4, in particular in the transition area from a side wall of the vehicle body 2 to the roof structure 4, at least one decorative strip 10 is arranged on the vehicle roof.

[0046] For example, in Fig. 2The decorative molding 10, shown in partial detail, is designed in multiple parts. It has a first molding section 12 and a second molding section 14 adjoining it longitudinally. The molding sections 12 and 14 butt against each other. An end of the first molding section 12 facing the second molding section 14 abuts an end face 13 of the second molding section 12; and vice versa. A plug-in connection 20 is provided for a reciprocal connection of the molding sections 12 and 14, the construction of which is described in more detail in the Figures 2 to 13 is shown.

[0047] As can be seen particularly from a synthesis of the Figures 3 to 11To clarify, strip section 12 has a receiving part 80. Strip section 14 has an insertion part 30. The insertion part 30 is designed to be complementary or corresponding to the receiving part 80. Strip section 12 has an approximately C-shaped profile in cross-section, which, in the final assembly position, comes into contact with an end face 13 against a correspondingly designed end face 15 of strip section 14.

[0048] While the strip section 12 is provided with a receptacle 82 at one longitudinal end and thus functions as a receptacle 80, the correspondingly designed strip section 14 has a insertion pin 32 projecting longitudinally from an end face 15 at its longitudinal end. In this respect, the strip section 14 functions as an insertion part 30 provided with the insertion pin 32. The insertion pin 32 can be inserted longitudinally into the receptacle 82, in particular by insertion or sliding.

[0049] Furthermore, as can be seen from the overall view of the Figures 2 to 13As can be seen, the insertion pin 32 has a top surface 33 which, in the final assembly position, rests against a correspondingly or complementarily designed inner surface 84 of a top surface 83 of the receptacle 82. Transversely to the longitudinal direction, the top surface 33 transitions into opposite outer surfaces 35, 36 of the insertion pin 32. Sliding surfaces 45, 46 are formed on the outer surfaces 35, 36, which, during the assembly of the insertion part 30 and the receptacle 80, slide along the correspondingly or complementarily designed inner surfaces of opposite side walls 85, 86 of the receptacle 82. During assembly, the outer surface 36, or rather its sliding surface 46, slides along the inner surface of the side wall 86. Similarly, the outer surface 35, or rather the sliding surface 45, slides along an inner surface of the side wall 85 of the receptacle 82.

[0050] As especially in the Figures 8 and 9To clarify, extensions 87, 88, projecting inwards and towards each other, extend from the lower end of the side cheeks 85, 86, which face away from the upper surface 83. The extensions 87, 88 can extend essentially parallel to the upper surface 83, while the side cheeks 85, 86 extend approximately parallel to a surface normal of the upper surface 83 or of the extensions 87, 88.

[0051] The side walls 85, 86, the extensions 87, 88 and the top surface 83 form an approximately C-shaped profile in cross-section. The outer dimensions and the outer contour of the insertion pin 32 are designed to correspond to the inner geometry of the receptacle 82.

[0052] During assembly, and at the latest upon reaching a final assembly position, the upwardly oriented inner surfaces of the projections 87, 88, directed towards the top 83, come into contact with the outer underside 34 of the insertion pin 32. In this way, the side walls 85, 86 and the projections 87, 88 formed on or integrally molded to them enclose or grip the outer edge or outer surfaces 35, 36 of the insertion pin 32.

[0053] With respect to a vertical axis and a transverse axis, both of which extend approximately perpendicular to the longitudinal direction of the decorative strip 10, a positive-locking, mutual connection between the insertion pin 32 and the receptacle 82 can be achieved in this manner. For mutual fixation in the longitudinal direction, two locking elements 53, 54 are provided on the underside 34 of the insertion pin 32 or are integrally formed thereon. The locking elements 53, 54 are designed as elastic spring tongues 63, 64. The spring tongues 63, 64, or the locking elements 53, 54, are designed to be complementary or corresponding to counter-locking elements 89, 90 in the area of ​​the projections 87, 88.

[0054] Upon reaching a final assembly configuration, the locking element 53 engages with the opposing locking element 89 in a snap-fit ​​manner. Simultaneously, the locking element 54 engages with the opposing opposing locking element 90 in a snap-fit ​​and thus positive-locking manner.

[0055] The counter-locking elements 89, 90 are formed as recesses 99, 100 in the inwardly projecting extensions 87, 88 of the side cheeks 85, 86. The recesses 99, 100 are designed as through-openings of the extensions 87, 88, which adjoin the inner edge 93, 94 of the respective extensions 87, 88 and thus form an edge recess of the inner edges 93, 94.

[0056] The locking elements 53, 54 protrude from the underside 34 of the insertion pin 32 in such a way that, with respect to a vertical axis of the decorative strip 10, they are at the same level as the extensions 87, 88, while the opposite outer sides 35, 36 of the insertion pin 32 are virtually enclosed in the circumferential direction by the extensions 87, 88 and the adjoining side cheeks 85, 86.

[0057] Extending outwards from the side walls 85, 86, longitudinally oriented sealing lips 95, 96 made of an elastomeric material are arranged. By means of the sealing lips 95, 96, a far-reaching sealing arrangement of the trim strip 10 on the outside of the vehicle body 2 can be achieved. The trim strip 10, or the strip section 12, 14, as well as the insert part 30 or the receiving part 80, can be made of a thermoplastic material. The trim strip 10 and / or its strip sections 12, 14 can be manufactured as injection-molded parts and / or as extruded parts.

[0058] The locking elements 53, 54 can each be set back from the outer surfaces 35, 36 in the transverse direction of the insertion pin 32, so that they do not protrude from the outer surfaces 35, 36. As can be seen in particular in the overall view of the Figures 3 to 7As shown in Figure 10, the insertion pin 32 has a head section 38, a longitudinally adjoining middle section 40, and a longitudinally adjoining base section 39. The head section 38 forms a free end section of the insertion pin 32, located away from the strip section 14. The base section 39, on the other hand, adjoins the strip section 14, which projects slightly outwards from the insertion pin 32, in the longitudinal direction.

[0059] Head section 38, base section 39, and middle section 40 can be designed as a single unit, for example, as an injection-molded plastic component. They can be designed as a single unit or in multiple units with the strip section 14, or connected to it separately. A fastening element 60 is also shown on the underside of the strip section 14, which is designed, for example, as a fastening clip and serves for mounting at a correspondingly designed fastening point on the vehicle body 2.

[0060] The locking elements 53, 54 are arranged with a base on the head section 38 or are integrally formed therewith. The locking elements 53, 54 extend with their free ends into the central section 40. They point towards the base section 39. At their free ends, the locking elements 53, 54 each have an end stop 55, 56. Each of the two end stops 55, 56 has a stop surface 65 which faces the base section 39, or whose surface normal extends in the longitudinal direction of the insertion part 30, opposite to the mounting direction of the insertion part 30, into the receiving part 80.

[0061] The counter-locking element 89, 90 formed on the receiving part 80 has a correspondingly designed counter-stop 91, 92. The counter-stop 91, 92 has a stop surface 101 with a surface normal that extends essentially longitudinally in the assembly direction.

[0062] In this way, and upon reaching a final assembly position, as is the case, for example, in Fig. 2 As shown, the counter-locking elements 53, 54, with their stop surfaces 65 provided at the end stops 55, 56, rest against the complementary stop surfaces 101 of the counter-stops 91, 92. In this way, the strip section 12 can be fixed longitudinally to the strip section 14.

[0063] Upon reaching the final assembly configuration, the end face 13 of the strip section 12 is in contact with the end face 15 of the strip section 14. This mutual contact may require a type of press fit, ensuring that the end faces 13 and 15 lie firmly against each other in the longitudinal direction with as little gap as possible, but in any case without play, when the locking elements 53 and 54 engage positively with the counter-locking elements 89 and 90.

[0064] In the Figures 2 and 3It is further shown that a contact surface 57, 58 is formed on the outer sides of the free ends of the locking elements 53, 54 and the spring tongues 63, 64, respectively. This contact surface faces outwards in a transverse direction and, upon reaching the final assembly position, comes into contact with the inner edge 93, 94 of the respective extension 87, 88 adjacent to the corresponding counter-locking element 89, 90. The contact surfaces 57, 58, which come into contact with the inner edges 93, 94 in a transverse direction, ensure that the locking elements 53, 54 remain in contact with the counter-locking elements 89, 90 and do not penetrate too far into the recesses 99, 100 formed by the counter-locking elements 89, 90.

[0065] As particularly in Fig. 2The locking elements 53, 54 are shown accessible from below. In the case of a decorative strip 10 composed of several strip sections 12, 14, which, for example, has been removed from the vehicle body 2, a release position can be achieved particularly easily by accessing the locking elements 53, 54. This is done by moving the locking elements 53, 54 towards each other and inwards. The locking mechanism can then be released, and the insertion pin 32 can be pulled out of the receptacle 82 in the opposite direction to the assembly direction.

[0066] On the underside 34 of the insertion pin 32, two webs 49, 50 projecting from the underside 34 are arranged in the head section 38 or formed on the insertion pin 32. Towards its free end, the head section 38 can have a chamfer 59 or chamfer, which further enables the insertion part 30 not only to be connected to the receiving part 80 before assembly on the motor vehicle 1, but also to be inserted into the receptacle 82 of a receiving part 80 already attached to the motor vehicle body 2. Initial insertion of the insertion part 30 into the receiving part 80 can be carried out at a predetermined angle, for example, at the angle of the chamfer 59 at the free end of the head section 38.

[0067] The webs 49, 50 can have a tapered chamfer 51, 52 towards the free end of the head section 38. The webs 50, 51 can also be arranged or aligned approximately in a straight line extending from the head section-side end of the locking elements 53, 54. As further shown in Fig. 2 As shown, the outer sides of the webs 49, 50 can rest against the mutually facing inner edges 93, 94 of the extensions 87, 88 and thus contribute to a further centering of the insertion part 30 and the receiving part 80.

[0068] Furthermore, a structure-reinforcing ridge 41 can be formed on the underside 34 of the insert part 30. The ridge 41 can, as in particular in the Figures 3 to 6The web 41 extends from the head section 38 into the base section 39. It can penetrate a recess 47 or 48 of the central section 40 longitudinally, thereby subdividing the central section 40 into the two recesses 47 and 48 adjacent to it laterally. The recesses 47 and 48 are bounded externally by the outer sides 35 and 36, which also function as connecting webs between the head section 38 and the base section 39.

[0069] The web 41 can have a C-shaped profile. The web 41 can have a longitudinally extended web section 42, which extends longitudinally from the head section 38 into the base section 39. In or adjacent to the base section 39, the web 41 can transition into a web section 43 that is wider in the transverse direction. The end faces of the web section 43 facing the opposite outer sides 35, 36 can also slide into contact with the inner edges 93, 94 of the side cheeks 85, 86 or their extensions 87, 88. As further described in Fig. 2As shown, the extensions 87, 88 can each have an obliquely inwardly projecting chamfer 103, 104 towards their longitudinal end, i.e. adjacent to the front face 30 of the receptacle 82, by means of which a particularly simple insertion of the webs 49, 50, the locking elements 53, 54 as well as the web section 43 into the area between the side cheeks 85, 86, in particular into the area between the extensions 87, 88, can take place.

[0070] In particular, the central section 40, which can also be described as a cage structure, allows for a certain degree of flexible deformation of the insertion pin 32, thus compensating for any tolerances on the vehicle even after assembly. Any bending forces arising from manufacturing tolerances can therefore be counteracted particularly easily and effectively. Ultimately, the proposed plug connection 20 provides a particularly simple, reciprocal plug connection between strip sections 12 and 14 of a trim strip 10, requiring minimal effort. It also enables rapid assembly with high holding forces and can be detached without damage.Various assembly scenarios can be implemented, and the plug connection also enables precise positioning and dimensionally accurate and durable arrangement of the decorative strip 10 on a motor vehicle body 2.

[0071] The illustrated embodiments merely show possible configurations of the development, for which numerous further variants are conceivable during development. The exemplary embodiments shown are in no way to be interpreted as limiting with regard to the scope, applicability, or configuration possibilities of the development. The present description merely shows the person skilled in the art one or a few possible implementation(s) of an embodiment. Thus, a wide variety of modifications can be made to the function and arrangement of the described elements without departing from the scope of protection defined by the following claims or their equivalents.
