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 cab, and to a seat, for example a vehicle seat. State of the art

[0002] DE 10 2011 119 072 B4 discloses a vehicle seat mounting structure comprising a kit of identically designed assemblies, each containing a reinforcement element and a bracket. The assemblies can be stacked vertically one above the other.

[0003] DE 10 2018 105 408 A1 discloses an industrial truck with a driver's cab that has a driver's seat for an operator. A seat support supports the driver's seat and is detachably connected to at least one side wall of the driver's cab. A fastening means is attached to at least one side wall of the driver's cab and is designed to allow the seat support to be attached to the side walls at at least two different heights. Task

[0004] The invention is based on the object of improving a kit, for example an assembly kit, of the type mentioned at the outset, in particular of achieving a standardization of individual parts which can be joined together to form several different seat support structures in order to avoid additional manufacturing costs and tooling costs, and of providing a corresponding seat. Solution

[0005] This object is achieved according to the invention by a kit for fastening a seat in a driver's cab, wherein the kit comprises at least a plurality of end support elements and a plurality of side support elements, wherein in each case a pair of end support elements and a pair of side support elements can be assembled or combined to form a plurality of seat support structures for fastening the seat to a cab floor.

[0006] Because the kit comprises at least a plurality of end support elements and a plurality of side support elements, wherein a pair of end support elements and a pair of side support elements can be assembled or combined to form a plurality of seat support structures for fastening the seat to a cabin floor, the manufacturing costs of individually manufactured seat support structures and tooling costs can be reduced.

[0007] The advantages achieved by the invention consist, in particular, in enabling the standardization of individual parts, in particular support elements (namely, end support elements and side support elements), for forming or assembling seat support structures that differ at least in shape and / or dimensions. The support elements can be designed such that, as individual parts, they are suitable for use in multiple positions within a driver's cab, including their functionality. For example, driver's cabs can have differently designed cab floors and / or driver's seats, whereby a suitable seat support structure can be assembled from the support elements of the kit according to the invention for different driver's cabs.

[0008] The driver's cab can be a truck cab or driver's cab. For example, the truck can include two cab-over-engine vehicles with a medium-height or high-mounted cab. The seat support structure can be adapted to different cab configurations 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, standard, luxury, basic, and / or relaxation seats.

[0009] Advantageous embodiments, which can be used individually or in combination with one another, are the subject of the subclaims.

[0010] The support elements, e.g., the end support elements, may have different shapes and / or dimensions. For example, the end support elements may have different height dimensions and / or length dimensions and / or width dimensions.

[0011] The support elements, e.g., the side support elements, may have different shapes and / or dimensions. For example, the side support elements may have different height dimensions and / or length dimensions and / or width dimensions.

[0012] The front support elements and the side support elements can be designed or assembled in such a way that a plurality of seat support structures can be formed which differ at least in their shapes and / or dimensions.

[0013] 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 at least by a material fit, a force fit, and / or a form fit. The end support elements and the side support elements can include common welding interfaces, soldering interfaces, riveting interfaces, and / or other interface areas. The corresponding support elements can be connected to one another via at least one weld nut.

[0014] For example, seat support structures can be designed as frame structures. The seat support structures (when the support elements are assembled) can have a substantially square or rectangular plan view in plan view.

[0015] The end support elements can form end faces, for example, a front and a rear face. The side support elements can be arranged between the end support elements. The side support elements can connect the end support elements to one another.

[0016] 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 brackets that can be arranged on the cabin floor.

[0017] The floor connection interfaces may have through-holes. Using suitable fastening elements, 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.

[0018] The side support elements can each have a seat connection interface. For example, the seat connection interfaces can have through-holes. Using suitable fastening elements, 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.

[0019] The floor connection interfaces and / or the seat connection interfaces can be formed in one piece, in particular in one piece, with the respective support elements.

[0020] In a further embodiment, the floor connection interfaces and / or the seat connection interfaces may comprise screws, bolts, holes and / or welds, rivets and / or solder joints.

[0021] At least one formable or formed first seat support structure may comprise a pair of identically formed end support elements which are to be aligned or are aligned parallel to one another and a pair of identically formed side support elements which are to be aligned or are aligned parallel to one another.

[0022] At least one formable or formed second seat support structure may comprise a pair of differently formed end support elements which are to be aligned or oriented perpendicular to one another and a pair of identically formed side support elements which are to be aligned or oriented parallel to one another.

[0023] At least one formable or formed 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.

[0024] The kit may comprise at least one set of end support elements which are substantially L-shaped.

[0025] The kit may comprise a set of end support elements which are substantially I-shaped.

[0026] In a further development, the kit can comprise at least one set of end support elements which are substantially Z-shaped.

[0027] The kit may comprise a set of side support elements having an upper edge, a lower edge sloping to the upper edge, and a wall connecting the upper edge and the lower edge.

[0028] The kit may comprise a set of side support elements having an upper edge, a lower edge parallel to the upper edge and a wall connecting the upper edge and the lower edge.

[0029] In other words, the kit may comprise a plurality of sets of identically designed support elements and a plurality of sets of differently designed support elements.

[0030] For example, the kit can comprise a plurality of differently designed or identically designed end support elements. The end support elements can be designed as end frame parts or end walls.

[0031] For example, the kit may comprise a plurality of differently designed or identically designed side support elements. The side support elements may be designed as side frame parts or side walls.

[0032] The support elements, i.e. the front support elements and the side support elements, can be designed as sheet metal profiles and / or support profiles and / or support plates.

[0033] The object is also achieved according to the invention by a seat, in particular a vehicle seat or driver's seat, having 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 cab, wherein the seat support structure is assembled from a kit.

[0034] The kit may comprise at least a plurality of differently designed end support elements and a plurality of differently designed side support elements.

[0035] The kit may comprise at least a plurality of identically designed end support elements and a plurality of identically designed side support elements.

[0036] A pair of end support elements and a pair of side support elements can be combined or assembled to form multiple seat support structures for attaching the seat to a cabin floor. The respective pairs can be formed from identical support elements or from different support elements. Any combination of different support elements and / or identical support elements with each other or with each other can be implemented to the greatest extent possible.

[0037] The kit may be suitable for forming a plurality of different seat support structures, comprising at least a plurality of differently formed front support elements and a plurality of differently formed side support elements.

[0038] Because the kit comprises at least a plurality of differently designed end support elements and a plurality of differently designed side support elements, wherein a pair of end support elements and a pair of side support elements can be assembled or combined to form a plurality of seat support structures for fastening the seat to a cabin floor, the manufacturing costs of individually manufactured seat support structures and tooling costs can be reduced.

[0039] The support elements may differ from one another at least in their shapes and / or dimensions and may be provided for assembling a plurality of differently designed seat support structures for fastening different seats in different driver cabs.

[0040] The advantages achieved by the invention consist, in particular, in enabling the standardization of individual parts, in particular 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, as individual parts, they are suitable for use in multiple positions within a driver's cab, including their functionality. For example, driver's cabs can have differently designed cab floors and / or driver's seats, whereby a suitable seat support structure can be assembled from the support elements of the kit according to the invention for different driver's cabs.

[0041] The driver's cab can be a truck cab or driver's cab. For example, the truck can include two cab-over-engine vehicles with a medium-height or high-mounted cab. The seat support structure can be adapted to different cab configurations 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, standard, luxury, basic, and / or relaxation seats. Figures and embodiments of the invention

[0042] 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.

[0043] Corresponding parts are provided with the same reference numerals in all figures.

[0044] One in the Fig. 1 schematically illustrated seat 100 of 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 spatial directions running perpendicular to one another. A longitudinal direction x of a seat 100 installed in the vehicle runs largely horizontally and preferably parallel to a vehicle longitudinal direction which corresponds to the normal direction of travel of the vehicle. A transverse direction y running perpendicular to the longitudinal direction x is also oriented horizontally in the vehicle and runs parallel to a vehicle transverse direction. A vertical direction z runs perpendicular to the longitudinal direction x and perpendicular to the transverse direction y. In a seat 100 installed in the vehicle, the vertical direction z preferably runs parallel to a vehicle vertical axis.

[0045] The position and direction specifications used, such as front, rear, top, and bottom, refer to the viewing direction of an occupant sitting in the seat 100 in a normal seating position, with the seat 100 installed in the vehicle, in a position of use suitable for passenger transport with the backrest 104 upright and oriented in the direction of travel as usual. However, the seat 100 can also be installed or moved in a different orientation, for example, transversely to the direction of travel. Unless otherwise described, the seat 100 is constructed mirror-symmetrically to a plane running perpendicular to the transverse direction y.

[0046] The backrest 104 can be pivotably mounted on a seat part 102 of the seat 100. For this purpose, the seat 100 can optionally include a fitting 106, in particular an adjustment fitting, a rotary fitting, a locking fitting, or a wobble fitting.

[0047] The position and direction specifications used, such as radial, axial, and circumferential, refer to a rotational axis 108 of the fitting 106. Radial means perpendicular to the rotational axis 108. Axial means in the direction of or parallel to the rotational axis 108.

[0048] The seat 100 can optionally include a longitudinal adjustment device 110. The longitudinal adjustment device 110 includes, 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.

[0049] For clarity, the first rail element 114 is referred to as the upper rail 114 in the following description. This upper rail 114 (also called a running rail or carriage) is assigned to the seat 100 and is configured to support this seat 100. The second rail element 116 is referred to below as the lower rail 116. The lower rail 116 is fixed and connected, for example, to the floor of a vehicle.

[0050] Seat support structures 210 are used to install a seat 100 in a driver's cab (not shown in detail), also called a driver's cab or driver's cab, for example, of an industrial truck or a truck. For example, seat support structures 210 can be used to adapt seats 100 to be installed to different cab floors with different conditions and / or different windshield heights.

[0051] Fig. 2A to 2C together show a schematic representation of a kit 200 according to the invention for a seat support structure 210 for fastening a seat 100 in a driver's cab, wherein the kit 200 comprises at least a plurality of end support elements 220a to 220c and a plurality of side support elements 230a to 230f.

[0052] The kit 200 may comprise at least a plurality of end support elements 220a to 220c and a plurality of side support elements 230a to 230f, wherein a pair of end support elements 220a to 220c and a pair of side support elements 230a to 230f are each connected to a plurality of seat support structures 210, 210a to 210d (in the Fig. 3 to 5) for securing the seat 100 to a cabin floor.

[0053] Because the kit 200 comprises at least a plurality of end support elements 220a to 220c and a plurality of side support elements 230a to 230f, manufacturing costs of individually manufactured seat support structures 210, 210a to 210d and tooling costs can be reduced.

[0054] The front support elements 220a to 220c and the side support elements 230a to 230f can be designed or assembled in such a way that a plurality of seat support structures 210, 210a to 210d can be formed that differ at least in their shapes and / or dimensions.

However, optionally, additional or alternatively, L-shaped end support elements 220a, 220b of different lengths and / or widths and / or heights can be provided. The L-shaped end support elements 220a, 220b can be designed as identical parts, for example, as symmetrical identical parts, and differ only in their dimensions. Two "larger" L-shaped end support elements 220a can form a pair. Two "smaller" L-shaped end support elements 220b can form a pair.

[0056] The end support elements 220a, 220b can each comprise a wall 222, for example a supporting wall, and a lower edge 224 projecting perpendicularly from the wall 222. The lower edge 224 can form a supporting foot or a support foot and can be arranged at a lower end of the wall 222.

[0057] The 200 kit can be used in Fig. 2A shown second set 204 of end support elements 220c, which are substantially I-shaped. In the illustrated embodiment according to Fig. 2A, only one I-shaped end support element 220c is shown, 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 each of the L-shaped end support elements 220a, 220b.

[0058] The end support element 220c can be formed from only a substantially flat lower edge 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.

[0059] The sets 202, 204 may comprise end support elements 220a to 220c that differ in shape and / or dimensions.

[0060] The end support elements 220a to 220c can each have a floor connection interface 240. The floor connection interfaces 240 can be formed by the lower edges 224 in the L-shaped end support elements 220a, 220b. The floor connection interface 240 of the I-shaped end support element 220c can be formed as an extension section or extension plate arranged on the base plate 226.

[0061] The floor connection interfaces 240 may have through-holes 242 arranged in grooves. Fastening elements or connecting elements, such as screws, bolts, and / or rivets, can be arranged countersunk through the grooves.

[0062] The 200 kit can be used in Fig. 2B. The side support elements 230a to 230d can each comprise an upper edge 232, a lower edge 234 extending obliquely relative to the upper edge 232, and a wall 236, in particular a supporting wall, connecting the upper edge 232 and the lower edge 234. The lower edge 234 and the upper edge 232 can each protrude perpendicularly from the wall 236.

[0063] In cross-section, the upper edge 232, the lower edge 234, and the wall 236 may form a U-shape. The side support elements 230a to 230d may have conically tapered edges. The side support elements 230a and 230b and the side support elements 230c and 230d are designed to correspond to one another. The side support elements 230a and 230b may be identical parts with mirror symmetry and, for example, form a pair. The side support elements 230c and 230d may be identical parts with mirror symmetry and, for example, form a pair. In the illustrated embodiment according to Fig. 2B, four side support elements 230a to 230d are shown, for example in triangular form, but triangular side support elements 230a to 230d of different lengths and / or widths and / or heights can be provided.

[0064] The 200 kit can be used in Fig. 2C. The side support elements 230e, 230f can each comprise an upper edge 232, a lower edge 234 running parallel to the upper edge 232, and a wall 236, in particular a supporting 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. 2C shows two side support elements 230e, 230f, for example, rectangular or square in shape. However, optionally, additional or alternatively, rectangular or square end support elements 230e, 230f of different lengths and / or widths and / or heights can be provided. The end support elements 230e, 230f can be designed as identical parts, for example, as symmetrical identical parts, and differ only in their dimensions. Two "larger" side support elements 230f can form a pair. Two "smaller" side support elements 230e can form a pair.

[0065] The sets 206, 208 can therefore comprise side support elements 230a to 230f that differ in shape and / or dimensions.

[0066] 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. Using suitable fastening elements or connecting elements, for example screws and / or bolts, the respective seats 100 can be connected to the respective seat support structures 210 via the seat connection interfaces 250. The seat connection interfaces 250 can be formed by the upper edges 232 of the respective side support elements 230a to 230f.

[0067] The end support elements 220a to 220c and the side support elements 230a to 230f can have corresponding connecting interfaces 260. The connecting interfaces 260 can have connecting tabs, connecting bridges, and / or connecting webs. The connecting interfaces 260 of the side support elements 230a to 230f can also be formed by side edges. The connecting interfaces 260 of the end support elements 220a to 220c can also be formed as side edges. The end support elements 220a to 220c and the side support elements 230a to 230f can be positively connected to one another at least at their connecting interfaces 260.
