Description

[0001] The invention relates to a mounting system for mounting a headrest on a backrest of a vehicle seat, comprising at least two receptacles which are or can be fastened to the backrest and comprising at least two fastening elements, wherein the fastening elements each have a plug-in receptacle for a support rod of the headrest, wherein one of the fastening elements can be locked in each of the receptacles.

[0002] Furthermore, the invention relates to a vehicle seat for a motor vehicle, the headrest of which is fastened to its backrest by the mounting system according to the invention.

[0003] Mounting systems of the type mentioned above are known from the prior art. Typically, a seat track of the vehicle seat, i.e., an area of ​​the vehicle seat on which a vehicle occupant can sit, is defined depending on the available width of a vehicle interior in which the vehicle seat can be arranged. This definition is usually vehicle-specific, with at least the distance between the support rods of the headrest and / or the position of the headrest in relation to the backrest usually varying. A backrest suitable for the respective vehicle model is then typically manufactured, with the receptacles for the fastening elements arranged accordingly.

[0004] From published patent application WO 2011 / 160 779 A1, a backrest with a plastic body is known. An insert can be fastened to the plastic body, in which insert two guide sleeves for supporting rods of a headrest can be arranged. To adjust the center position of the headrest relative to the backrest, a variety of different inserts are provided, which differ in the position of the guide sleeves. While this provides a certain degree of modularity because the plastic body can be used for multiple vehicle types, a custom insert must still be manufactured for each vehicle type. A generic assembly system is known from published patent application DE 10 2014 011 563 A1.

[0005] The invention is based on the object of creating an improved vehicle seat which can be produced in an advantageous modular and cost-effective manner.

[0006] The object underlying the invention is achieved by a mounting system having the features of claim 1. According to the invention, it is provided that the receptacles and the fastening elements are designed such that the respective fastening element can be fastened in the respective receptacle in different positions and / or orientations in order to adapt a distance between the plug-in receptacles on the backrest to a distance between the support rods of the headrest and / or to adapt a position of the headrest on the backrest.Such a design of the receptacles and fastening elements creates advantageous modularity because, by combining the receptacles with the fastening elements, different distances between the plug-in receptacles for the support rods can be set, i.e., a plurality of headrests with different distances between their support rods can be fastened to the same fastening elements, and different positions of the plug-in receptacles of the fastening elements relative to the backrest can be fixed, i.e., the position of the headrest relative to the backrest can also be changed. Different positions of the fastening element in the respective receptacle is to be understood in particular as meaning that the fastening element can be moved in the receptacle and can be fixed in at least two different positions with regard to a longitudinal and / or transverse extent of the receptacle in the receptacle.Different orientations of the fastening element in the respective receptacle are understood to mean, in particular, that the fastening element can be rotated relative to the respective receptacle and can be fixed in at least two different orientations. For this purpose, the fastening element is preferably designed to be rotationally symmetrical and / or to have a single or multiple mirror symmetry, so that it can advantageously be rotated about its longitudinal central axis.

[0007] According to a preferred development of the invention, the receptacles and the fastening elements are designed symmetrically in such a way that the respective fastening element can be arranged in the respective receptacle in a form-fitting manner in at least two different orientations and / or positions. Such a symmetrical design of the receptacles and the fastening elements advantageously ensures that the intended orientations and / or positions are predetermined by the form-fitting arrangement, so that they are adapted to previously known distances between support rods and the fastening elements cannot be fastened arbitrarily in the receptacles. In particular, this advantageously further reduces the likelihood of incorrect assembly, in which the fastening elements are inadvertently arranged in an orientation or position in which the distances between their plug-in receptacles do not match any of the distances between the support rods.

[0008] According to the invention, the respective receptacle has a rectangular inner contour. The rectangular inner contour of the receptacle has the advantage that the possible positions and / or orientations of one of the fastening elements are securely fixed in the receptacle. The inner contour refers in particular to the cross-section, i.e. the shape or dimension resulting from a length and a width of the receptacle. The receptacle itself is preferably cuboid-shaped, i.e., in addition to the length and width, it also has a depth. More preferably, the depth corresponds to a depth of at least one of the fastening elements to be arranged in the receptacle, so that the fastening element advantageously sits flush with the receptacle when inserted.

[0009] According to the invention, the respective fastening element has a square or rectangular outer contour which interacts positively with the inner contour of the receptacle. The outer contour of the fastening element interacting positively with the inner contour of the receptacle advantageously ensures that the possible positions and / or orientations of the fastening element in the receptacle are particularly securely fixed. The outer contour refers in particular to the cross-section, i.e. the shape or dimension resulting from the length and width of the fastening element. With a square outer contour, the length corresponds to the width; with a rectangular outer contour, the length is greater than the width (or vice versa). The fastening element itself is preferably cuboid-shaped, i.e., in addition to the length and width, it also has a depth.The depth of the fastening element preferably corresponds to the depth of the receptacle. Furthermore, at least one of the dimensions of the outer contour of the fastening element preferably corresponds to one of the corresponding dimensions of the inner contour of the receptacle, so that the fastening element rests against two opposing inner sides of the receptacle in at least one of the positions and / or orientations of the fastening element in the receptacle. For example, the width of the fastening element corresponds to the width of the receptacle, so that the fastening element is displaceable in the receptacle, in particular along the longitudinal extent of the receptacle, and in each position thus attainable advantageously always rests against two side surfaces and is securely held or guided.

[0010] Particularly preferably, the plug-in receptacle of at least one of the fastening elements is formed eccentrically in the fastening element. Due to the eccentric design of the plug-in receptacle, the distance between the plug-in receptacles is particularly advantageously determined by the alignment of the fastening element with respect to the receptacle. In particular, the distance can then be determined or is determined without the fastening element changing its position. Preferably, the plug-in receptacle is arranged on the fastening element in such a way that a change in the distance is achieved by rotating the fastening element about a rotational axis, in particular about its longitudinal central axis.

[0011] According to a preferred development of the invention, the plug-in receptacle of at least one of the fastening elements is formed centrally in the fastening element. Due to the central design of the plug-in receptacle, the distance between the plug-in receptacles is particularly advantageously determined via the position of the fastening element in the receptacle. In particular, the distance can then be determined or is determined without the fastening element changing its orientation by being rotated relative to the receptacle. Preferably, the plug-in receptacle is arranged on the fastening element in such a way that a change in the distance is achieved by displacing the fastening element in the receptacle.

[0012] It is particularly preferably provided that an outer contour of at least one of the fastening elements corresponds to an inner contour of at least one of the receptacles. This advantageously ensures that the fastening element is held in the receptacle in a completely form-fitting manner and that its position is securely fixed. The plug-in receptacle of the fastening element is then preferably formed eccentrically in the fastening element, so that the distance between the plug-in receptacle and the plug-in receptacle in the other receptacle is advantageously determined by adjusting the orientation of the fastening element in the receptacle. Furthermore, each of the possible orientations of the fastening element in the receptacle is preferably coordinated with at least one of the orientations or positions of one of the other fastening elements such that at least one of the headrests can be arranged on the backrest.Preferably, the inner contour and the outer contour are rectangular, as described above. Furthermore, the outer contour of at least one of the fastening elements and the inner contour of at least one of the receptacles are preferably circular or have the shape of a regular polygon (with equal side angles and equal interior angles), for example, a square, so that they are rotationally symmetrical. With a regular polygon, advantageously, as many possible orientations can be clearly defined as the polygon has sides. A square can therefore be defined in four possible orientations.

[0013] According to the invention, an outer contour of at least one of the fastening elements deviates from an inner contour of at least one of the receptacles in such a way that, in the assembled state, a free space remains in the receptacle. This advantageously ensures that the orientation and / or position of the fastening element in the receptacle can be determined particularly flexibly. Preferably, the fastening element has a rectangular outer contour and the receptacle has a rectangular inner contour, wherein one of the dimensions of the outer contour of the fastening element corresponds to one of the corresponding dimensions of the inner contour of the receptacle, so that the fastening element rests against two mutually opposite inner sides of the receptacle in all positions and / or orientations of the fastening element in the receptacle.For example, the width of the fastening element corresponds to the width of the receptacle, so that the fastening element can be moved in the receptacle, in particular along the longitudinal extent of the receptacle, and in each position that can be reached in this way always rests against two side surfaces and is securely held or guided. The free space then arises, depending on the position, between one of the two remaining side surfaces of the fastening element and the respective side surface of the receptacle. Preferably, the fastening element can be fastened in the receptacle in such a way that the fastening element also rests against the third side surface of the receptacle, so that the free space arises only between the remaining side surfaces of the fastening element and the remaining side surfaces of the receptacle.Alternatively or additionally, the fastening element can be fastened in the receptacle in such a way that the fastening element does not rest on the third side surface of the receptacle, so that free spaces are created on both sides of the fastening element, so that the number of possible positions is advantageously increased.

[0014] According to the invention, a compensating element or filling element is provided which is designed to be inserted into the free space, filling the free space, wherein a common outer contour of the fastening element and the compensating element in the receptacle corresponds to the inner contour of the receptacle. The compensating element advantageously ensures that the free space is completely filled, so that the fastening element and the compensating element are held together in the receptacle with a positive fit and securely fixed. In particular, the fastening element is then unable to be accidentally displaced in the receptacle, and the stability of the connection between the fastening element and the receptacle is advantageously increased.

[0015] Particularly preferably, the fastening element and the compensating element comprise retaining means for securing the compensating element to the fastening element for pre-assembly. Providing retaining means on the fastening element and the compensating element offers the advantage that a structural unit consisting of the fastening element and the compensating element can be produced even before the fastening element is secured in the receptacle, facilitating assembly.

[0016] According to a preferred embodiment of the invention, a plurality of identically designed receptacles and a plurality of identically and / or differently designed fastening elements, as well as optionally a plurality of identically and / or differently designed compensating elements, are provided. This creates a particularly advantageous modularity, so that the greatest possible variability is achieved with as few vehicle-specific parts as possible.

[0017] The vehicle seat according to the invention for a motor vehicle has a backrest and a headrest fastened to the backrest, wherein the headrest has two support rods. The vehicle seat is characterized by the features of claim 8 in that the headrest is fastened to the backrest by the mounting system according to the invention. This also results in the advantages already mentioned. The vehicle seat is preferably designed as a single seat. Alternatively, the vehicle seat is designed as a bench seat for two or three vehicle occupants. When the vehicle seat is designed as a bench seat, the backrest of the bench seat preferably has two receptacles for the support rods per seat, i.e. either four or six, so that two or three headrests can be fastened to the backrest accordingly.

[0018] Further advantages and preferred features and combinations of features emerge in particular from the above description and from the claims. The invention will be explained in more detail below with reference to the drawings. Fig. 1 an advantageous mounting system for mounting a headrest on a backrest of a vehicle seat, Fig. 2A and Fig. 2B different embodiments of fastening elements for attaching the headrest to the backrest, and Fig. 3A and Fig. 3B further different embodiments of fastening elements.

[0019] Fig. Figure 1 shows an advantageous mounting system 1 for mounting a headrest 2 on a backrest 3 of a vehicle seat (not shown in detail). The vehicle seat, or rather the backrest 3 of the vehicle seat, is designed as a single seat in the present embodiment. According to an embodiment not shown, the vehicle seat is designed as a bench seat.

[0020] In the present embodiment, a first receptacle 4 and a second receptacle 5 are attached to the backrest 3. A first fastening element 6 is locked in the first receptacle 4. A second fastening element 7 is locked in the second receptacle 5. The fastening elements 6, 7 each have a plug-in receptacle 8 for a support rod 9 of the headrest 2. The fastening elements 6, 7 are in the Fig. 2A and Fig. 2B, each shown in a top view. It should be noted that the actual geometry of the fastening elements 6, 7 and the receptacles 4, 5 is merely exemplary and is shown in a simplified manner.

[0021] The first fastening element 6 has a square outer contour and is cuboid-shaped overall. Three of its outer sides rest against three inner sides of the first receptacle 4, which is also cuboid-shaped and has a rectangular outer contour. A free space thus remains between the remaining outer side of the first fastening element 6 and the remaining inner side of the first receptacle 4. A compensating element 10 is arranged in this free space and completely fills the free space. The compensating element 10 is preferably fastened to the first fastening element 6 by means of holding means (not shown) designed for this purpose.

[0022] The common outer contour of the first fastening element 6 and the compensating element 10 corresponds to the inner contour of the first receptacle 4. Thus, the first fastening element 6 and the compensating element 10 are held in the first receptacle 4 in a completely form-fitting manner, preferably largely free of play.

[0023] The second receptacle 5 also has a rectangular inner contour and is cuboid-shaped overall. In the present exemplary embodiment, its dimensions are identical to those of the first receptacle 4. According to an exemplary embodiment not shown, the first receptacle 4 and the second receptacle 5 have different dimensions.

[0024] The second fastening element 7 has a rectangular outer contour that corresponds to the inner contour of the second receptacle 5, so that the outer contour of the second fastening element 7 interacts with the inner contour of the second receptacle 5 in a form-fitting manner on all four sides. The fact that the first fastening element 6 and the second fastening element 7 have different outer contours is merely exemplary. According to an embodiment not shown, the two fastening elements 6, 7 alternatively have identical dimensions.

[0025] In the present exemplary embodiment, the two fastening elements 6, 7 also differ in the position of the plug-in receptacles 8. The plug-in receptacle 8 is formed centrally in the first fastening element 6, i.e. a longitudinal central axis of the plug-in receptacle 8 corresponds to a vertical axis of the first fastening element 6. In order to adapt a distance between the plug-in receptacles 8 of the backrest 3 to a distance between the support rods 9 of the headrest 2, the first fastening element 6 can be arranged in the first receptacle 4 not only in the position shown, but also in a further position in which the compensating element 10 is then arranged on the other side of the first fastening element 6. The first fastening element 6 is therefore displaced along a longitudinal extent of the first receptacle 4.

[0026] In contrast, the plug-in receptacle 8 is formed off-center in the second fastening element 7, in the present exemplary embodiment, displaced along a longitudinal extent of the second fastening element 7. According to a further exemplary embodiment not shown, the plug-in receptacle 8 is alternatively or additionally displaced along a transverse extent of the second fastening element 7. To adjust the distance as described above, the second fastening element 7 can be arranged not only in the orientation shown, but also in a further orientation in which the second fastening element is rotated by 180° about its vertical axis.

[0027] The inner contour of the plug-in receptacles 8 is identical, as is the outer contour of the two support rods 9, so that in the present embodiment, the first fastening element 6 can be arranged in the second receptacle 5 and the second fastening element 7 in the first receptacle 4. This is shown in the Fig. 3A and Fig. 3B. The second fastening element 7 is shown in the Fig. 3A, the first mounting element 4 is also arranged in a second orientation, namely rotated by 180° around its vertical axis. The first fastening element 6 is in the Fig. 3B is exemplarily displaced in the second receptacle 5 into a second position in which the compensating element 10 is arranged on another side of the first fastening element 6.

[0028] According to an alternative embodiment not shown, the fastening elements 6, 7 are assigned to exactly one of the receptacles 4, 5 due to their respective outer contour, i.e. they can only be inserted into one of the two receptacles 4, 5 because the fastening elements 6, 7 and / or the receptacles 4, 5 each have different dimensions, as described above.
