Abstract
Description
[0001] VEHICLE SEAT OF A MOTOR VEHICLE
[0002] The invention relates to a vehicle seat of a motor vehicle.
[0003] Vehicle seats are known in various designs from the prior art. These usually comprise a seat cushion structure, in which a driver of a motor vehicle can be arranged while seated, and a backrest structure, against which the driver of the motor vehicle can lean his or her back while seated. In known vehicle seats, both the seat cushion structure and the backrest structure each comprise a seat padding spanned by a covering means. The covering means is directly or indirectly and permanently attached to the seat structure, in particular to the seat cushion structure and the backrest structure.
[0004] Replacing a damaged or worn seat cover on conventional vehicle seats is only possible at a workshop or upholsterer. In particular, it is not possible for the vehicle user to customize the vehicle seat.
[0005] An object of an embodiment of the invention is to propose a vehicle seat in which replacement of a cover means is simplified.
[0006] This object is achieved by a vehicle seat of a motor vehicle with at least one frame-like seat structure which surrounds a free space, with at least one receiving unit which is fastened to the at least one seat structure and which comprises at least one receptacle, with at least one planar, elastic cover means which, in an arrangement fastened to the receiving unit, completely or partially overlaps the free space of the seat structure, with at least one suspension means which is fastened to an edge section of the cover means, and with at least one tensioning means which comprises at least one tensioning hook to which at least one of the at least one suspension means is fastened, and which comprises at least one latching hook by means of which the tensioning means can be or is fastened releasably to the at least one receptacle of the receiving unit.
[0007] Because the cover element can be releasably secured to the at least one receptacle of the receiving unit by means of suspension means attached to the edge portion of the cover element via at least one tension hook, the cover element can be easily attached to and detached from the receiving unit. This facilitates the interchangeability of the cover element.
[0008] The covering material may comprise threads or filaments, which may be made of natural fibers or synthetic fibers. Furthermore, embodiments are conceivable in which the covering material consists of a natural material, such as leather or the like.
[0009] In principle, it is conceivable for the elastic covering means to be fixed or secured to the receiving unit in an undeformed, i.e., unstretched, state. To increase seating comfort, it is advantageous if the tensioning means can be transferred from a pre-attached functional position, in which the tensioning means is arranged adjacent to one of the at least one receptacles of the receiving unit, by rotation away from the free space into a joined functional position, in which the tensioning means is secured in the receptacle of the receiving unit.
[0010] By transferring the clamping device from the pre-attached functional position to the joined functional position, the clamping device is moved away from the free space, i.e., outward from the reference device. This stretches and tightens the reference device.
[0011] Arranging the reference means on the clamping means and transferring it from the pre-attached functional position into the joined functional position can be facilitated if the clamping means comprises a substantially U-shaped cross-section which is formed by a longitudinal section and two transverse sections running transversely or obliquely to the longitudinal section, wherein the longitudinal section comprises at least one of the at least one clamping hook and wherein at least one of the transverse sections comprises at least one of the at least one latching hook and / or if the at least one receptacle of the receptacle unit comprises at least one recess which can be engaged behind and which, in a joined arrangement of the clamping means, in particular in the joined functional position, is engaged behind at least by the latching hook.
[0012] In such a case, the clamping device in the pre-assembled functional position rests with a transverse section on a wall surrounding the recess of the receiving unit and in the joined functional position engages behind the recess at least with the locking hook against the joining direction.
[0013] As a result, the clamping device is designed like a lever and is supported on or within the recess of the holder of the holder unit when transferred from the pre-attached functional position to the joined functional position.
[0014] In a further development of the latter embodiment, it proves to be advantageous if the clamping means comprises at least one of the at least one latching hook on a first transverse section and if a holding section is arranged on a second transverse section running parallel or obliquely to the first transverse section and spaced apart from the first transverse section by the longitudinal section at the end thereof facing away from the longitudinal section, which holding section runs parallel or obliquely to the longitudinal section and which projects in a direction facing away from the first transverse section, wherein the holding section engages in the recess of the receiving unit of the receiving unit or in a further recess of the receiving unit in the pre-attached functional position and engages behind the recess of the receiving unit or the further recess of the receiving unit opposite to the joining direction in the joined functional position.
[0015] In such a case, the clamping means engages with the holding section in the recess of the receptacle of the receiving unit, whereby the transfer from the pre-attached functional position to the joined functional position is guided and thus facilitated.
[0016] In addition, the holding section in the joined functional position forms an additional rear grip opposite to the joining direction, which increases the forces that can be absorbed by the clamping device.
[0017] In principle, it is conceivable for the clamping device to be formed from various individual components. The vehicle seat can be designed with fewer components if the clamping device, in particular the longitudinal section, the first transverse section, the second transverse section, the at least one holding section, the at least one clamping hook, and / or the at least one clamping hook form a common, one-piece component, in particular a plastic injection-molded part, and / or if the at least one clamping hook is formed by a mandrel formed by an opening in the longitudinal section.
[0018] The suspension means can, in principle, be of any desired design, provided that it connects the cover means to the tensioning means. In embodiments of the vehicle seat, it is provided that the suspension means is essentially inelastic and flexibly bendable and can be detachably fastened or secured to the cover means by means of a coupling section, in particular by means of a frictional connection or a positive connection, or indetachably fastened or secured to the cover means, in particular by means of a material connection, a frictional connection or a positive connection, and comprises, at an end facing away from the coupling section, a suspension section comprising at least one through-opening, with which the suspension means can be arranged or is arranged suspended from the at least one tensioning hook of the tensioning means.
[0019] Because the suspension means comprises a through-opening, the suspension means can be easily arranged on the at least one tensioning hook of the tensioning means. Because the suspension means is inelastic, the extension of the suspension means is not changed when a tensioning force is introduced into the suspension means by transferring the tensioning means from the pre-attached functional position to the joined functional position. In this case, "inelastic" means that the suspension means is not stretchable. Because the suspension means is flexibly bendable, it can fulfill its function of connecting the cover means to the tensioning means even when the tensioning means is rotated from the pre-attached functional position to the joined functional position, for example, by 90°. Because the suspension means is flexibly bendable, the suspension means can adapt flexibly in terms of its shape.
[0020] It proves particularly advantageous if the at least one tension hook is formed by a mandrel formed by an opening in the longitudinal section. The suspension means with its opening can be easily arranged on this mandrel.
[0021] Furthermore, the clamping device can be manually gripped through the aperture, for example, with a finger or a tool. This can facilitate the release of the clamping device from the receptacle of the holding unit in the assembled functional position, as the finger or the tool can act directly on the locking hook and / or the holding section in such a way that it is released from the rear grip position.
[0022] In such a case, the locking hook on the side facing the holding section and / or the holding section on the side facing the locking hook can comprise a recess into which a finger or a tool can be arranged and which is engaged in a release direction for releasing the locking hook and / or the holding section from the rear grip position.
[0023] In principle, it is conceivable for the tensioning means to comprise only a single tensioning hook and for the suspension means to comprise only a single through-opening. Furthermore, embodiments of the vehicle seat are conceivable in which the tensioning means comprises at least two tensioning hooks and / or in which the suspension section of the suspension means comprises a number of through-openings corresponding to the number of tensioning hooks of the associated tensioning means, which are configured to correspond, in particular complement, to the tensioning hooks in terms of their arrangement and shape.
[0024] Because the clamping device can comprise multiple clamping hooks, at least two, and the suspension device has a corresponding number of through-holes, the forces generated and transmitted by the clamping device when tensioning the cover can be distributed across multiple points of application. This reduces the risk of damage to a clamping hook and / or an opening and ensures the longevity of the clamping device and suspension device.
[0025] The covering means can generally be designed to form a seat surface or a support surface for a back. The frame-like seat structure can, for example, comprise a seat cushion structure. In this case, the elastic covering means forms a cover on which a driver of a motor vehicle can be seated.
[0026] Furthermore, the frame-like seat structure can include a backrest structural part against which a user of the motor vehicle can lean their back when sitting on the vehicle seat. In this case, the elastic covering means forms a support surface for a user of the motor vehicle.
[0027] It proves to be advantageous if the planar, elastic covering means comprises a completely closed surface or a surface comprising a plurality of user-detectable through openings.
[0028] If the elastic cover material has a closed surface, underlying components of the vehicle seat can be visually concealed.
[0029] If the planar, elastic covering means comprises a plurality of surfaces comprising user-detectable through-openings, the elastic covering means can comprise a planar mesh. The user-detectable openings can, for example, be polygonal and in particular have a triangular, quadrangular, in particular square, hexagonal, or octagonal cross-section. Furthermore, the user-detectable through-openings can be rounded and have a circular, oval, or elliptical cross-section.
[0030] Furthermore, embodiments of the vehicle seat are conceivable in which the vehicle seat comprises at least one cushion body which is arranged in or on the free space of the seat structure.
[0031] If the vehicle seat includes a cushioned body, the elastic covering means can be rested against it. This allows forces absorbed by the elastic covering means to be transferred to the cushioned body, reducing the load on the elastic covering means.
[0032] If the free space of the seat structure is free of material, the elastic cover is designed like a hammock. This allows the weight forces exerted by the vehicle seat user to be absorbed solely by the cover.
[0033] Finally, it proves to be advantageous if the receiving unit and the frame-like seat structure form a one-piece common component or if the receiving unit comprises a component that is separate or separable from the frame-like seat structure and that can be fixed or secured to the seat structure detachably, in particular by means of frictional or positive locking, or non-detachably, in particular by means of material connection, frictional or positive locking.
[0034] If the receiving unit and frame-like seat structure form a single, integrated component, the vehicle seat can be designed with a reduced number of components. In this case, the at least one receptacle is formed directly in the frame-like seat structure. If the receiving unit comprises a component that is separate or separable from the frame-like seat structure, existing vehicle seats can be easily retrofitted. In this case, the receiving unit can be designed as an adapter frame.
[0035] Further features, details and advantages of the invention emerge from the appended patent claims, from the drawings and the following description of a preferred embodiment of the vehicle seat.
[0036] The drawing shows:
[0037] Figure 1 A perspective, exploded front view of an embodiment of the vehicle seat;
[0038] Figure 2 A detailed view and a sectional view along the line BB of a reference means with hanging means arranged thereon according to the embodiment of Figure 1;
[0039] Figure 3 A sectional view of a joining of a suspension means with a locking hook of a tensioning means in a pre-joined functional position of the locking means;
[0040] Figure 4 The locking means and the suspension means according to Figure 3 in a joined functional position.
[0041] Figure 1 shows an exploded view of an embodiment of a vehicle seat of a motor vehicle, generally designated by the reference numeral 2.
[0042] In the exemplary embodiment illustrated in Figure 1, the vehicle seat 2 comprises two frame-like seat structures 4. A receiving unit 6 designed as an adapter frame is arranged on each of the frame-like seat structures 4, each of which is secured to a seat structure 4 and comprises a plurality of receptacles 8. One of the two seat structures 4 forms a backrest structure against which a user of a motor vehicle can be arranged leaning their back. Another seat structure 4 forms a seat cushion structure on which a driver of a motor vehicle can be arranged sitting.
[0043] Furthermore, the vehicle seat 2 comprises planar, elastic covering means 10, each of which, in an arrangement secured to a receiving unit 6, completely covers a free space 12 of the seat structure 4. The planar, elastic covering means 10 are designed such that they each comprise a plurality of user-detectable through-openings, in particular a mesh structure.
[0044] Several suspension means 14 are arranged at the edge sections of the cover means 10. The suspension means 14 are inelastic, meaning they cannot stretch along their length. Furthermore, the suspension means 14 are designed to be flexible and bendable.
[0045] Figure 2 shows a detailed view of the suspension means 14, which are attached to a cover means 10. In this case, the suspension means 14 can comprise a single through-opening 16, or a suspension means 14 can comprise several openings 16 arranged next to one another. Also shown in Figure 2 is a section along the line BB. This shows that, on the one hand, the opening 16 is through-opening and completely enclosed. As a result, the suspension means 14 forms a tab- or eyelet-like structure on its suspension section 18, which encompasses the opening 16. On the side opposite the suspension section, the suspension means 14 is attached to the cover means 10 by a coupling section 21.
[0046] Figure 3 shows the process of joining a suspension means 14 to a clamping means 20. In the embodiment shown in Figures 3 and 4, the clamping means 20 comprises a clamping hook 22, to which a suspension means 14 can be secured with its through-opening 16. Furthermore, the clamping means 20 comprises a locking hook 24, which, in a joined arrangement, engages behind a receptacle 8 of the receiving unit 6 with respect to a joining direction 26.
[0047] The clamping device 20 shown in Figures 3 and 4 has a U-shaped cross-section. It comprises a longitudinal section 28, on which two transverse sections are arranged, extending transversely to the longitudinal section 28. The locking hook 24 is arranged on a first transverse section 30. A holding section 34 is arranged on a second transverse section 32 opposite the first transverse section 30. The holding section 34 is arranged on the end of the second transverse section 32 facing away from the longitudinal section 28 and extends in a direction away from the locking hook 24.
[0048] In the embodiment shown in Figures 3 and 4, the clamping hook 22 is formed by a mandrel formed by an opening in the longitudinal section 28.
[0049] The receptacle 8 of the receiving unit 6 is formed by a recess 36 that can be gripped behind. In the embodiments shown in Figures 3 and 4, the receptacle 8 of the receiving unit 6 comprises two recesses 36 that can be gripped behind.
[0050] In the upper illustration according to Figure 3, the suspension means 14 is moved toward the clamping means 20. The suspension means 14 is hooked with its through-opening 16 onto the locking hook 24 of the clamping means 20, which is formed as a mandrel.
[0051] Figure 3 shows the clamping device 20 in a pre-assembled functional position. In this position, the clamping device 20 rests with its second transverse section 32 against a wall of the receptacle 8 surrounding the recess 36. The holding section 34 engages in one of the recesses 36.
[0052] Figure 4 shows the illustration according to Figure 3 in a joined functional position. In this position, the locking means has been rotated by 90°. The rotation occurs in a direction away from the free space 12. In the joined functional position, the locking hook 24 engages behind the recess 36, and the holding section 34 engages behind the recess 36. Both the locking hook 24 and the holding section 34 thus engage behind the receptacle opposite to the joining direction 26. The suspension means 14 arranged on the clamping hook 22 of the clamping means 20 is flexibly bent in its suspension section 18.
[0053] By transferring the clamping device 20 from the pre-attached functional position to the joined functional position, the cover element 10 is subjected to a clamping force. The features of the invention disclosed in the above description, in the claims, and in the drawings can be essential, both individually and in any combination, for the implementation of the invention in its various embodiments within the scope of the following claims.
