Description

[0001] The invention relates to a kit for a seat support structure for fastening a seat, for example a vehicle seat, in a driver's cabin, for example a driver's cab or driver's cabin, and to a seat, for example a vehicle seat. State of the art

[0002] German patent DE 10 2011 119 072 B4 discloses a vehicle seat mounting structure comprising a kit of identically designed modules, each containing a reinforcement element and a bracket. The modules can be stacked vertically on top of each other.

[0003] From DE 10 2018 105 408 A1, a forklift truck with a driver's cab, which has a driver's seat for one operator, is known. A seat support carries the driver's seat and is detachably connected to at least one side wall of the driver's cab, wherein a fastening means is attached to the at least one side wall of the driver's cab and is designed so that the seat support can be attached to the side walls at at least two different heights.

[0004] From EP 3 013 633 B1 a console for a vehicle seat is known, comprising a square console body. Task

[0005] The invention is based on the objective of improving a kit, for example an assembly kit, of the type mentioned at the outset, in particular achieving a standardization of individual parts that can be assembled to form several different seat support structures in order to avoid additional manufacturing costs and tooling costs, and providing a corresponding seat. Solution

[0006] This problem is solved according to the invention by a kit for attaching a seat in a driver's cabin, wherein the kit comprises at least a plurality of front support elements and a plurality of side support elements, wherein each pair of front support elements and each pair of side support elements can be assembled or combined to form several seat support structures for attaching the seat to a cabin floor.

[0007] Because the kit includes at least a plurality of front support elements and a plurality of side support elements, with each pair of front support elements and each pair of side support elements being able to be assembled or combined to form several seat support structures for attaching the seat to a cabin floor, the manufacturing costs of individual manufactured seat support structures and tooling costs can be reduced.

[0008] The advantages achieved with the invention consist in particular of enabling the standardization of individual parts, especially support elements (namely front and side support elements), for the formation and assembly of seat support structures that differ at least in shape and / or dimensions. The support elements can be designed such that they are suitable as individual parts for use in multiple positions within a driver's cab, including their functionality. For example, driver's cabs may have differently designed cab floors and / or driver's seats, and a suitable seat support structure can be assembled from the support elements of the inventive kit for different driver's cabs.

[0009] The driver's cab can be the driver's cabin or cab of a truck. For example, the truck can be a forward-control vehicle with a medium-high or high-mounted cab. The seat support structure can be adapted to different conditions in the driver's cab to increase comfort and convenience for professional drivers at work. Furthermore, the seat support structure can be adapted to different seats, such as driver's seats, whether comfort seats, standard seats, luxury seats, basic seats, and / or reclining seats.

[0010] Advantageous embodiments, which can be used individually or in combination with each other, are the subject of the dependent claims.

[0011] The structural elements, i.e., for example, the end support elements, can have different shapes and / or dimensions. For example, the end support elements can have different heights, lengths, and / or widths.

[0012] The load-bearing elements, i.e., for example, the side load-bearing elements, can have different shapes and / or dimensions. For example, the side load-bearing elements can have different height dimensions, length dimensions, and / or width dimensions.

[0013] The front support elements and the side support elements can be designed or assembled in such a way that several seat support structures can be formed that differ at least in their shapes and / or dimensions.

[0014] The end support elements and the side support elements can have corresponding connection interfaces. For example, the end support elements can be connected to the side support elements by at least a material bond, a force bond, and / or a form-fit connection. The end support elements and the side support elements can include common weld interfaces, solder interfaces, rivet interfaces, and / or other interface areas. The corresponding support elements can be connected to each other via at least one weld nut.

[0015] For example, seat support structures can be designed as frame structures. In plan view, the seat support structures (when the supporting elements are assembled) can have a substantially square or rectangular plan.

[0016] The end support elements can form end faces, for example, a front and a back. The side support elements can be arranged between the end support elements. The side support elements can connect the end support elements to each other.

[0017] The end support elements can each have a floor connection interface. For example, the floor connection interfaces can be designed as plates, feet and / or tabs that can be arranged on the cabin floor.

[0018] The floor connection interfaces may have through holes. Using suitable fasteners, such as screws and / or bolts, the respective seat support structures can be fixed to the cabin floor via the floor connection interfaces of the end support elements.

[0019] The side support elements can each have a seat connection interface. For example, the seat connection interfaces can have through holes. Using suitable fasteners, such as screws and / or bolts, the respective seats can be connected to the respective seat support structures via the seat connection interfaces of the side support elements.

[0020] The floor connection interfaces and / or the seat connection interfaces can be formed in one piece, in particular as a single unit, with the respective support elements.

[0021] In another embodiment, the floor connection interfaces and / or the seat connection interfaces can include screws, bolts, holes and / or welds, rivets and / or soldered joints.

[0022] At least one trainable or trained first seat support structure may comprise a pair of identically designed front support elements that are to be aligned or oriented parallel to each other, and a pair of identically designed side support elements that are to be aligned or oriented parallel to each other.

[0023] At least one formable or formed second seat support structure may comprise a pair of differently formed end support elements that are to be aligned or oriented perpendicular to each other, and a pair of identically formed end support elements that are to be aligned or oriented parallel to each other.

[0024] At least one trainable or trained third seat support structure and fourth seat support structure may differ in their shapes and / or dimensions from the first and second seat support structures.

[0025] The kit can include at least one set of end support elements, which are essentially L-shaped.

[0026] The kit may include a set of end support elements, which are essentially I-shaped.

[0027] In a further training course, the kit can include at least one set of end support elements, which are essentially Z-shaped.

[0028] The kit can include a set of side support elements with a top edge, a bottom edge sloping towards the top edge, and a wall connecting the top edge and the bottom edge.

[0029] The kit can include a set of side support elements with a top edge, a bottom edge running parallel to the top edge, and a wall connecting the top edge and the bottom edge.

[0030] In other words, the kit can comprise a plurality of sets of identically designed support elements and a plurality of sets of differently designed support elements.

[0031] For example, the kit can include multiple end support elements, either with different or identical designs. These end support elements can be designed as end frame components or end walls.

[0032] For example, the kit can include multiple side support elements, either with different or identical designs. These side support elements can be designed as side frame components or side walls.

[0033] The load-bearing elements, i.e. the end load-bearing elements and the side load-bearing elements, can be designed as sheet metal profiles and / or beam profiles and / or support plates.

[0034] The object is further solved according to the invention by a seat, in particular a vehicle seat or driver's seat, with at least one seat part, a backrest connected to the seat part and a seat support structure for fastening, in particular for supporting, the seat in a driver's cabin, wherein the seat support structure is assembled from a kit.

[0035] The kit can include at least a plurality of differently designed front support elements and a plurality of differently designed side support elements.

[0036] The kit can include at least a plurality of identically designed end support elements and a plurality of identically designed side support elements.

[0037] Each pair of end support elements and each pair of side support elements can be assembled or combined to form multiple seat support structures for attaching the seat to a cabin floor. The respective pairs can be composed of identical or different support elements. Virtually any combination of different and / or identical support elements can be implemented.

[0038] The kit may be suitable for forming several different seat support structures, comprising at least a plurality of differently designed front support elements and a plurality of differently designed side support elements.

[0039] Because the kit includes at least a plurality of differently designed front support elements and a plurality of differently designed side support elements, wherein each pair of front support elements and each pair of side support elements can be assembled or combined to form several seat support structures for attaching the seat to a cabin floor, the manufacturing costs of individual manufactured seat support structures and tooling costs can be reduced.

[0040] The support elements may differ from one another at least in their shapes and / or dimensions and may be intended for the assembly of a plurality of differently designed seat support structures for the attachment of different seats in different driver cabins.

[0041] The advantages achieved with the invention consist in particular of enabling the standardization of individual parts, especially support elements, for the formation or assembly of seat support structures that differ at least in shape and / or dimensions. The support elements can be designed such that they are suitable as individual parts for use in multiple positions within a driver's cab, including their functionality. For example, driver's cabs may have differently designed cab floors and / or driver's seats, and a suitable seat support structure can be assembled from the support elements of the inventive kit for different driver's cabs.

[0042] The driver's cab can be the driver's cabin or cab of a truck. For example, the truck can be a forward-control vehicle with a medium-high or high-mounted cab. The seat support structure can be adapted to different conditions in the driver's cab to increase comfort and convenience for professional drivers at work. Furthermore, the seat support structure can be adapted to different seats, such as driver's seats, whether comfort seats, standard seats, luxury seats, basic seats, and / or reclining seats. Figures and embodiments of the invention

[0043] The invention is explained in more detail below with reference to advantageous embodiments illustrated in the figures. However, the invention is not limited to these embodiments. The figures show: Fig. 1: schematic representation of a seat with a longitudinal adjustment device according to the state of the art, Fig. 2A to 2C: schematic representations of a kit according to the invention for a seat support structure for fastening a seat in a driver's cabin, comprising a plurality of front support elements and a plurality of side support elements, Fig. 3: a perspective view of a first seat support structure which can be assembled or is assembled from a pair of end support elements and a pair of side support elements of a kit according to the invention, Fig. 4: a perspective view of a second seat support structure, which can be assembled or is assembled from a pair of end support elements and a pair of side support elements of a kit according to the invention, Fig. 5: a perspective view of a third seat support structure, which can be assembled or is assembled from a pair of end support elements and a pair of side support elements of a kit according to the invention, and Fig. 6: a perspective view of a fourth seat support structure, which can be assembled or is composed of a pair of end support elements and a pair of side support elements of a kit according to the invention.

[0044] Corresponding parts are marked with the same reference symbols in all figures.

[0045] One in the Fig. A seat 100, schematically depicted in relation to the prior art, for example a vehicle seat and / or driver's seat, comfort seat, luxury seat, relaxation seat or standard seat, is described below using three mutually perpendicular spatial directions. A longitudinal direction x of a seat 100 installed in a vehicle runs largely horizontally and preferably parallel to a longitudinal direction of the vehicle, which corresponds to the vehicle's usual direction of travel. A transverse direction y, perpendicular to the longitudinal direction x, is also horizontally oriented in the vehicle and runs parallel to a transverse direction of the vehicle. A vertical direction z runs perpendicular to the longitudinal direction x and perpendicular to the transverse direction y. In a seat 100 installed in a vehicle, the vertical direction z preferably runs parallel to a vertical axis of the vehicle.

[0046] The position and direction designations used, such as front, rear, top, and bottom, refer to the viewing direction of an occupant seated in seat 100 in a normal seating position, with seat 100 installed in the vehicle in a suitable position for passenger transport, with the backrest 104 upright and oriented in the direction of travel as usual. However, seat 100 can also be installed or moved in a different orientation, for example, transversely to the direction of travel. Unless otherwise described, seat 100 is designed to be mirror-symmetrical about a plane perpendicular to the transverse direction y.

[0047] The backrest 104 can be pivotally mounted on a seat section 102 of the seat 100. For this purpose, the seat 100 can optionally include a fitting 106, in particular an adjustment fitting, swivel fitting, locking fitting or wobble fitting.

[0048] The position and direction specifications used, such as radial, axial, and circumferential, refer to a rotation axis 108 of the fitting 106. Radial means perpendicular to the rotation axis 108. Axial means in the direction of or parallel to the rotation axis 108.

[0049] The seat 100 can optionally include a longitudinal adjustment device 110. The longitudinal adjustment device 110 comprises, for example, a rail arrangement 112 with a first rail element 114 and a second rail element 116. The first rail element 114 is adjustable in the longitudinal direction x relative to the second rail element 116. The first rail element 114 is attached to the seat part 102. The second rail element 116 is attached to a structural element of a vehicle, for example, a vehicle floor.

[0050] For clarity, the first rail element 114 will be referred to as the upper rail 114 in the following description. This upper rail 114 (also called running rail or carriage) is assigned to the seat 100 and designed to support this seat 100. The second rail element 116 will be referred to as the lower rail 116. The lower rail 116 is fixed and, for example, connected to the floor of a vehicle.

[0051] To install a seat 100 in a driver's cab (also called driver's cabin or driver's cab), for example of a forklift or truck, seat support structures 210 are used. For example, seat support structures 210 can be used to adapt seats 100 to different cab floors with different conditions and / or different windshield heights.

[0052] Fig. Figures 2A to 2C together show in schematic representation a kit 200 according to the invention for a seat support structure 210 for fastening a seat 100 in a driver's cabin, wherein the kit 200 comprises at least a plurality of front support elements 220a to 220c and a plurality of side support elements 230a to 230f.

[0053] Kit 200 can comprise at least a plurality of end support elements 220a to 220c and a plurality of side support elements 230a to 230f, wherein each pair of end support elements 220a to 220c and each pair of side support elements 230a to 230f are connected to several seat support structures 210, 210a to 210d (in the Fig. 3 to 5 shown) for attaching the seat 100 to a cabin floor, or are assembled.

[0054] Because the kit 200 includes at least a plurality of front support elements 220a to 220c and a plurality of side support elements 230a to 230f, the manufacturing costs of individual manufactured seat support structures 210, 210a to 210d and tooling costs can be reduced.

[0055] The end support elements 220a to 220c and the side support elements 230a to 230f can be designed or assembled in such a way that several seat support structures 210, 210a to 210d, which differ at least in their shapes and / or dimensions, can be formed.

Two "larger" L-shaped end support elements 220a may form a pair. Two "smaller" L-shaped end support elements 220b may form a pair.

[0057] The end support elements 220a, 220b can each comprise a wall 222, for example a load-bearing wall, and a lower edge 224 projecting perpendicularly from the wall 222. The lower edge 224 can form a support foot or a bearing foot and be arranged at a lower end of the wall 222.

[0058] Kit 200 can be built in Fig. The second set 204 shown in 2A comprises end-bearing elements 220c, which are essentially I-shaped. In the illustrated embodiment according to Fig. Figure 2A shows only one I-shaped end support element 220c; however, I-shaped end support elements 220c of different lengths and / or widths can be provided. A "straight" I-shaped end support element 220c can form a pair with one of the L-shaped end support elements 220a, 220b.

[0059] The end support element 220c can consist of only a substantially planar lower or upper edge. In particular, the end support element 220c, i.e., the I-shaped end support element 220c, can be designed as a base plate 226.

[0060] Sentences 202 and 204 may include end-bearing elements 220a to 220c that differ in shape and / or dimensions.

[0061] The end support elements 220a to 220c can each have a ground connection interface 240. The ground connection interfaces 240 of the L-shaped end support elements 220a and 220b can be formed by the lower edges 224. The ground connection interface 240 of the I-shaped end support element 220c can be designed as an extension section or extension plate arranged on the base plate 226.

[0062] The floor connection interfaces 240 can have through holes 242 arranged in grooves. Fasteners or connecting elements, such as screws, bolts and / or rivets, can be countersunk in the grooves.

[0063] Kit 200 can be built in Fig. The third set 206 shown in Figure 2B comprises side support elements 230a to 230d. Each side support element 230a to 230d can comprise an upper edge 232, a lower edge 234 inclined to the upper edge 232, and a wall 236, in particular a load-bearing wall, connecting the upper edge 232 and the lower edge 234. The lower edge 234 and the upper edge 232 can each project perpendicularly from the wall 236.

[0064] In cross-section, the upper edge 232, the lower edge 234, and the wall 236 can form a U-shape. The side support elements 230a to 230d can have conically tapered edges. The side support elements 230a and 230b and the side support elements 230c and 230d are configured to correspond to each other. The side support elements 230a and 230b can be mirror-symmetrical identical parts and, for example, form a pair. The side support elements 230c and 230d can be mirror-symmetrical identical parts and, for example, form a pair. In the illustrated embodiment according to Fig. 2B shows four side support elements 230a to 230d, for example in the form of triangles, but triangular side support elements 230a to 230d of different lengths and / or widths and / or heights may be provided.

[0065] Kit 200 can be built in Fig. The fourth set 208 shown in Figure 2C comprises side support elements 230e, 230f. Each side support element 230e, 230f can comprise an upper edge 232, a lower edge 234 running parallel to the upper edge 232, and a wall 236, in particular a load-bearing wall, connecting the upper edge 232 and the lower edge 234. In cross-section, the upper edge 232, the lower edge 234, and the wall 236 can form a U-shape. In the illustrated embodiment according to Fig. Figure 2C shows two side support elements 230e, 230f, for example, rectangular or square in shape. However, optionally or alternatively, additional rectangular or square end support elements 230e, 230f of different lengths, widths, and / or heights may be provided. The end support elements 230e, 230f may be identical, for example, symmetrical, and differ only in their dimensions. Two "larger" side support elements 230f may form a pair. Two "smaller" side support elements 230e may form a pair.

[0066] Sentences 206 and 208 may therefore include side support elements 230a to 230f that differ in shape and / or dimensions.

[0067] The side support elements 230a to 230f can each have a seat connection interface 250. For example, the seat connection interfaces 250 can have through holes 252. The respective seats 100 can be connected to the respective seat support structures 210 via the seat connection interfaces 250 using suitable fastening elements or connecting elements, such as screws and / or bolts. The seat connection interfaces 250 can be formed by the upper edges 232 of the respective side support elements 230a to 230f.

[0068] The end support elements 220a to 220c and the side support elements 230a to 230f can have corresponding connection interfaces 260. The connection interfaces 260 can have connecting tabs, connecting bridges, and / or connecting webs.
