Description

The invention relates to a vehicle seat for commercial vehicles comprising a support structure and at least one cushioning element, wherein the at least one cushioning element is arranged on the support structure. The present invention is particularly applicable to commercial vehicles without a cab or with an open cab. Such commercial vehicles can include, for example, ride-on lawnmowers, small tractors, forklifts, and construction machinery. For such commercial vehicles, a simple, robust vehicle seat is generally desirable. Typically, such vehicle seats have a support structure, for example, a frame. A cushioning element is arranged on this support structure. To protect the cushioning element from mechanical influences and / or weather conditions, a protective cover is arranged on the cushioning element. To attach the upholstery element to the support structure, either the upholstery element and the support structure are bonded together, or inserts are incorporated into the upholstery element to create a mechanical connection to the support structure. Such connection techniques are disadvantageous because they either require a complex and therefore more expensive process, or because the upholstery element cannot be replaced due to the permanent connection to the support structure. Due to these connection types, discarded vehicle seats cannot be recycled, or only with great difficulty. Therefore, current vehicle seats do not offer sufficient sustainability. Document DE 103 54 065 A1 is known from the prior art. This document describes a vehicle seat comprising a cushioning element made of a rigid foam and a layer of soft foam. The cushioning element is designed as a seat component, and the rigid foam component has a surface that is at least partially congruent with the vehicle floor. This surface can be positively connected to the vehicle floor in the working position of the seat component. The seat component can be released from this positive connection by means of a hinge and can be installed in a non-use position. Furthermore, document DE 29 12 369 A1 is known. This document discloses a safety cushion for transporting persons in mines, comprising an open-cell foam filling covered with a flame-retardant skin and shaped to conform to the contours of the seat. The surface covering is also treated to increase electrical conductivity and prevent static discharge. The cover is textured to ensure a secure grip. The cushion is attached to the vehicle via mounting rails using molded grooves on the underside. The object of the present invention is to provide a vehicle seat which overcomes the aforementioned disadvantages. The problem is solved by the subject matter of independent claim 1. Advantageous embodiments are described in the dependent claims. The core idea of ​​the invention is a vehicle seat for commercial vehicles comprising a support structure and at least one cushioning element, wherein the at least one cushioning element is arranged on the support structure, wherein the support structure comprises at least one shell element, wherein the at least one cushioning element is formed from an integral foam, wherein the at least one cushioning element is attached to the at least one shell element by means of at least one screw-like fastening element, wherein the at least one screw-like fastening element engages directly in the integral foam. Integral foams are foams with a relatively large-pored interior and a compact surface with a closed outer skin. The robust, tough-elastic outer skin provides a high level of protection. The at least one cushioning element is therefore extremely resistant to mechanical stress and / or weathering. A protective cover is thus unnecessary. Advantageously, the at least one cushioning element does not have a cover. The integral foam is preferably a polyurethane (PUR) integral foam. Polyurethane is robust, permanently elastic, easy to clean, and resistant to oils, solvents, and many chemicals. The shape of the at least one cushioning element and / or the properties of the outer skin can be determined by the tooling used during manufacturing. The hardness of the polyurethane (PUR) can advantageously be varied by selecting different raw materials. Ideally, at least one upholstery element should have sufficient elasticity to ensure comfortable seating. According to the invention, the at least one screw-like fastening element engages directly in the integral foam. The at least one screw-like fastening element is thus in direct contact with the integral foam. The at least one screw-like fastening element is designed such that a sufficiently stable connection between the support structure and the at least one cushioning element is ensured. This provides a direct, insert-free foam screw connection. Due to the absence of inserts, the at least one cushioning element is homogeneous. This allows for simpler feeding into a recycling process. Since neither gluing nor the provision of insert parts is necessary, manufacturing is also simplified, thereby reducing production costs. In a particularly preferred embodiment, a releasable, positive-locking connection exists between the at least one screw-like fastening element and the at least one cushioning element. Besides the simpler manufacturing process, the components of a discarded vehicle seat can also be easily separated by loosening the screw-like fastening elements. Such separation is significantly simpler than gluing. The components can then be sorted and recycled. In a further preferred embodiment, the screw-like fastening element has a disc-shaped end section. The end section is preferably designed and intended to rest against the shell element. Preferably, the end section rests against a second surface of the shell element, which is opposite the first surface against which the at least one cushioning element rests. Furthermore, a core section is preferably arranged on the disc-shaped end section. Preferably, the core section is at least partially formed in a substantially pin-like manner. The core section is advantageously formed integrally with the end section at a first end. The second end of the core section is preferably designed as a needle-shaped, conical tip. According to a further preferred embodiment, the at least one shell element has at least one receptacle in which the screw-like fastening element is partially arranged. Preferably, the receptacle is T-shaped. In a second section of the receptacle, the end section of the screw-like fastening element is arranged. This second section is designed as a recess in the at least one shell element. The second section transitions into a first section, which is an opening in the at least one shell element. The core section of the screw-like fastening element is arranged in the second section of the receptacle. Preferably, the receptacle is open laterally so that the end section and the core section of the screw-like fastening element can be inserted laterally into the receptacle. In a further preferred embodiment, an external thread section is arranged on the core section. Preferably, the external thread section is self-tapping. The external thread section is thus advantageously designed such that it cuts the integral foam when screwed in. Advantageously, screwing the at least one screw-like fastening element into the at least one cushioning element creates a positive fit. Advantageously, the positive fit is releasable, so that the at least one screw-like fastening element can be unscrewed from the at least one cushioning element. Preferably, the external thread section forms a helical thread. In a further preferred embodiment, the core section has a core diameter and the external thread section has a flank diameter. The core diameter is the distance between the thread root, i.e., the deepest point of the thread, and the opposite thread root. The flank diameter is defined as the diameter of an imaginary, geometrically ideal circular cylinder (flank cylinder) that intersects the thread profile such that the widths of the resulting profile troughs and crests are equal. Preferably, the flank diameter is at least twice, and more preferably at least three times, larger than the core diameter. More preferably, the flank diameter is at least four times larger than the core diameter.Such a deep external thread ensures sufficient mechanical strength of the connection between the integral foam and the screw-like fastening element. According to a further preferred embodiment, the screw-like fastening element has a conical shape. The outer diameter of the screw-like fastening element thus tapers from the plate-like end section towards the second end of the core section. In a preferred embodiment, the support structure comprises a first shell element on which at least one first cushioning element is arranged. Preferably, the support structure comprises a second shell element on which at least one second cushioning element is arranged. Preferably, the first shell element and the at least one first cushioning element form a seat section of the vehicle seat. It is conceivable that several first cushioning elements are arranged on the first shell element. Thus, the first shell element and the several first cushioning elements would form the seat section of the vehicle seat. Preferably, the second shell element and the at least one second cushioning element form a back section of the vehicle seat. It is also conceivable that several second cushioning elements are arranged on the second shell element. Thus, the second shell element and the several second cushioning elements would form the back section of the vehicle seat.The first shell element and the second shell element can be made of a dimensionally stable plastic or a metal. The support structure can advantageously further comprise a support element to which the first shell element and the second shell element are attached. The support element can preferably be arranged on the body of the commercial vehicle. It is also conceivable that the support element is designed such that the backrest is tiltable relative to the seat. Preferably, a tilt adjustment device is provided by means of which the tilt of the backrest relative to the seat can be adjusted. In a further preferred embodiment, the support structure comprises only a shell element on which at least one first cushioning element and at least one second cushioning element are arranged. Preferably, a first section of the shell element and the at least one first cushioning element form a seat part of the vehicle seat. It is conceivable that several first cushioning elements are arranged on the first section of the shell element. Thus, the first section of the shell element and the several first cushioning elements would form the seat part of the vehicle seat. Preferably, a second section of the shell element and the at least one second cushioning element form a backrest part of the vehicle seat. It is conceivable that several second cushioning elements are arranged on the second section of the shell element. Thus, the second section of the shell element and the several second cushioning elements would form the backrest part of the vehicle seat.The shell element can be made of a dimensionally stable plastic or a metal. In a preferred embodiment, the vehicle seat has a short backrest. With such a short backrest, the backrest does not extend over the occupant's shoulder area. In tractors or forklifts, it is often preferred that, in an upright position, the backrest does not extend to the shoulder area. This allows the driver greater freedom of movement with regard to rotating the upper body, which is advantageous, for example, when reversing. Preferably, at least one upholstery element extends along a vertical axis Z', a horizontal axis Y', and a longitudinal axis X'. The backrest is provided at the rear section of the vehicle seat along the longitudinal axis X'. A front section of the vehicle seat along the longitudinal axis X' points forward in the normal direction of the occupant's gaze. Optionally, the front section points towards any operating elements of the commercial vehicle. The horizontal axis Y' extends along the lateral boundaries of the vehicle seat. In a further preferred embodiment, the at least one cushioning element has a main section and at least one projecting section. Preferably, the at least one projecting section extends beyond the main section. The main section forms the part that is in contact with the occupant. Preferably, the at least one screw-like fastening element engages in the projecting section. More preferably, the at least one screw-like fastening element engages only in the projecting section. This ensures that the screw-like fastening element does not impair the occupant's seating comfort in any way.The screw-like fastening element is therefore only provided in one area of ​​the seat, namely the projecting section, which does not contribute to the occupant's cushioning but serves exclusively to hold or fasten at least one cushioning element. Advantageously, the projecting section is designed to have a greater hardness and / or density than the main section. This can result in improved holding power for the screw-like fastening element. According to a further preferred embodiment, the at least one shell element has at least one trough-like recess in which the at least one projecting section is arranged. Preferably, the at least one trough-like recess is essentially complementary to the at least one projecting section. By arranging the projecting section in the trough-like recess, additional retention of the at least one cushioning element on the at least one shell element is achieved. According to a further preferred embodiment, the at least one cushioning element has a plurality of openings. These openings reduce the contact area with the occupant's body, thus enabling passive cooling through air circulation. Furthermore, improved usability under adverse weather conditions, such as soiling or wetness, is achieved because there is less surface area for moisture or dirt to accumulate. In addition, the mass of the at least one cushioning element, and consequently the manufacturing costs, are reduced. The task is still accomplished by a commercial vehicle with a vehicle seat according to one of the previously described embodiments. The commercial vehicle can be equipped with all the features already described above in relation to the vehicle seat, either individually or in combination, and vice versa. The commercial vehicle is preferably a vehicle without a cab or with an open cab. Examples include a ride-on lawnmower, a tractor, a forklift, or a construction vehicle. According to a preferred embodiment, the vehicle seat is attached to the body of the commercial vehicle.

For clarity, some components may not be labeled with a reference symbol in certain figures, but are identified elsewhere. Figures 1 to 4, 7, 10, 11 show a vehicle seat 1 for commercial vehicles 100, comprising a support structure 2 and at least one upholstery element 3, wherein the at least one upholstery element 3 is arranged on the support structure 2, wherein the support structure 2 comprises at least one shell element 4, 10, 12, wherein the at least one upholstery element 3 is formed from an integral foam, wherein the at least one upholstery element 3 is attached to the at least one shell element 4 by means of at least one screw-shaped fastening element 5, wherein the at least one screw-shaped fastening element 5 engages directly in the integral foam. The vehicle seat extends along a longitudinal axis X, a lateral axis Y, and a vertical axis Z. Advantageously, the vehicle seat 1 is mounted on a section of the body 101 of a commercial vehicle 100. This is indicated in Fig. 2. The vehicle seat 1 comprises a seat part 1a and a backrest part 1b. The support structure 2 can be designed differently: According to one embodiment, the support structure 2 comprises a first shell element 10 and a second shell element 12. According to another embodiment, the support structure 2 comprises only a shell element 4. According to the first embodiment, at least one first upholstery element 11 is arranged on the first shell element 10. Furthermore, at least one second upholstery element 13 is arranged on the second shell element 12. The first shell element 10 and the at least one first upholstery element 11 together form the seat section 1a of the vehicle seat 1. It is conceivable that several first upholstery elements 11 are arranged on the first shell element 10 and together form the seat section 1a. The second shell element 12 and the at least one second upholstery element 13 together form the backrest section 1b. It is conceivable that several second upholstery elements 13 are arranged on the second shell element 12 and together form the backrest section 1b. The two shell elements 10, 12 can be connected to each other by means of a support element.This support element could be arranged on the body 101 of the commercial vehicle 100 and thus serve to attach the vehicle seat 1 to the body 101. In a further embodiment, only one shell element 4 is provided. The shell element 4 comprises a first section 4a and a second section 4b. The first section 4a, together with at least one first upholstery element 11, forms the seat part 1a. It is conceivable that several first upholstery elements 11 are arranged on the first section 4a and together form the seat part 1a. The second section 4b, together with at least one second upholstery element 13, forms the backrest 1b. It is conceivable that several second upholstery elements 13 are arranged on the second section 4b and together form the backrest 1b. According to this embodiment, the shell element 4 can be arranged directly on the body 101. However, it is also conceivable that a support element is provided by means of which the attachment to the body 101 is effected. Shell elements 4, 10, 12 are so-called hard shells and consist of a dimensionally stable plastic or a metal or a metal alloy. A detachable, form-fitting connection exists between the at least one screw-like fastening element 5 and the at least one upholstery element 3. This detachable connection allows the at least one upholstery element 3 to be easily removed from the at least one shell element 4, 10, 11. This has the advantage that the at least one upholstery element 3 can be easily replaced. Furthermore, the components of a discarded vehicle seat 1 can be separated very easily. The separated components are then sorted by type. This means, for example, that the at least one upholstery element 3 does not contain any other elements, such as inserts, that would need to be removed before recycling. The components can therefore be easily recycled. As can be seen in Figures 4, 5, 6, 8, 9, and 10, the screw-like fastening element 5 has a disc-shaped end section 6. A core section 7 is arranged on the disc-shaped end section 6. This core section 7 has a pin-shaped area 7b. At one end, this transitions into a needle-shaped, conical tip 7c. At the opposite end, a pin-shaped area 7b transitions into a transition section 7d, which is essentially conical. The transition section 7d transitions into the end section 6 of the screw-like fastening element 5. A self-tapping external thread section 8 is arranged on the core section 7. By screwing in the screw-like fastening element 5, a positive fit is cut into the integral foam. The core section 7 has a core diameter 7a in its pin-like area 7b. The external thread section 8 has a flank diameter 8a. The flank diameter 8a is at least twice, preferably at least three times, and more preferably at least four times larger than the core diameter 7a. Such a deep external thread section 8 ensures the mechanical strength of the positive-locking connection between the screw-like fastening element 5 and the integral foam. The respective flanks of the external thread section 8 preferably have a sawtooth shape. Each flank has a lower surface 8b facing the end section 6 and being substantially parallel to it. The lower surface 8b forms an angle with an upper surface 8c. This angle is acute, lying in a range between 2° and 10°. The external thread section 8 further has an outer diameter 8d, which is the maximum diameter of the external thread section 8. Advantageously, the outer diameter 8d of the external thread section 8 decreases continuously in one direction from the end section 6 to the tip 7c of the core section 7. The fastening element 5 thus preferably has a substantially conical shape. The at least one screw-shaped fastening element 5 is arranged in a receptacle 9 of the shell element 4, 10, 11. The receptacle 9 has a first section 9a in which the plate-shaped end section 6 is arranged. A second section 9b adjoins this first section 9a in the form of an opening through the shell element 4, 10, 11. The screw-shaped fastening element 5 projects through this opening. Preferably, a portion of the core section 7 is arranged in the opening. According to the embodiment, the core section 7 has a transition region 7d in which the core diameter increases towards the end section 6. Preferably, this transition region 7d is conical. The conical transition region 7d partially abuts an inner surface of the second section 9b in the form of an opening.The end section 6 rests against an inner surface of the first section. In a screwed-in state, the screw-like fastening element 5 thus holds the at least one cushioning element 3 in place by this contact of the end section 6. The at least one cushioning element 3 then rests at least partially against an inner surface 16 of the shell element 4, 10, 12. The receptacle 9 is essentially T-shaped. The at least one upholstery element 3 extends along a height axis Z', which corresponds to the thickness of the at least one upholstery element 3. Furthermore, the at least one upholstery element extends along a longitudinal axis X' and a width axis Y'. The screw-shaped fastening element 5 can be arranged such that it extends substantially perpendicularly, i.e., substantially along a vertical axis Z', into the at least one cushioning element 3. This is shown, for example, in Fig. 5 and Fig. 8. The screw-shaped fastening element 5 can also be screwed obliquely upwards into the at least one cushioning element 3. A central axis 5a of the screw-shaped fastening element 5 thus forms an angle α with a plane spanned by the longitudinal axis X' and the lateral axis Y'. This angle α is preferably in a range between 10° and 80°, more preferably in a range between 20° and 70°. The at least one cushioning element 3 can have a main section 3a and at least one projecting section 3b. The main section 3a comprises the surface that is in contact with the occupant and the portion of the cushioning element 3 that is intended to provide elasticity or cushioning. The main section 3a thus has a certain thickness. The main section 3a can also have a varying thickness. The main section 3a of a first upholstery element 11, i.e., an upholstery element for the seat section 1a, can have side panels that serve to support the occupant's thighs. The main section 3a of a second upholstery element 13, i.e., an upholstery element for the back section 1b, can have side panels that serve to support the occupant's back. Further features, such as curves, etc., which promote ergonomic seating, are also conceivable. The at least one projecting section 3b extends beyond the main section 3a. Preferably, the at least one projecting section 3b extends beyond the main section 3a along the height axis Z' of the at least one cushioning element 3. The at least one screw-like fastening element 5 preferably engages exclusively in the projecting section 3b. This has the advantage that the cushioning properties in the main section 3a of the at least one cushioning element 3 are not impaired by the screw-like fastening element 5. It is also conceivable that the properties of the at least one cushioning element 3 in the projecting section 3b differ from those of the main section 3a. For example, the projecting section 3b could have a greater hardness or density. This could provide improved retention of the screw-like fastening element 5. In Figures 5 and 6, the fastening element 5 is arranged in the projecting section 3b. In Figure 5, the fastening element is arranged essentially perpendicularly in the projecting section 3b. In Figure 6, the fastening element 5 is angled into the projecting section 3b. In contrast, no projecting section is shown in Figure 8. Here, the fastening element 11 is arranged in the main section 3a. The at least one shell element 4, 10, 12 can have at least one trough-like recess 14. This trough-like recess 14 is designed and intended to receive at least one projecting section 3b of the cushioning element 3. Preferably, the at least one trough-like recess 14 is substantially complementary to the at least one projecting section 3b. This preferably allows for an additional positive fit, which provides additional retention of the at least one cushioning element 3 on the shell element 4. In the embodiments shown in the figures, the projecting sections 3b are essentially cylindrical with a rectangular or square cross-section. The trough-like recesses 14 also have a rectangular or square cross-section, complementary to this. The trough-like recesses 14 are clearly visible in Figs. 4, 5, 6, 9 and 10. Naturally, the trough-like recesses 14 can be provided in the first section 4a as well as in the second section 4b of a one-piece shell element 4, as well as in the first shell element 10 and the second shell element 12. The at least one receptacle 9 for the screw-shaped fastening element 5 can be arranged in the recessed receptacles 14. In the embodiment according to Fig. 5, the screw-shaped fastening element 5 projects perpendicularly into the projecting section 3b. The receptacle 9 is arranged in a lower wall 14a, which lies in a plane spanned by the lateral axis Y' and the longitudinal axis X'. In the embodiment according to Fig. 6, the screw-shaped fastening element 5 projects obliquely upwards into the projecting section 3b. The receptacle 9 is arranged in a lateral wall 14b, which is substantially perpendicular to the lower wall 14a. Figure 11 shows an embodiment in which the at least one cushioning element 3 has a plurality of openings 15. The provision of these openings 15 reduces the contact area with the occupant's body. This allows for passive cooling through air circulation. Furthermore, improved usability under adverse weather conditions, such as soiling or wetness, is achieved because there is less surface area for the accumulation of moisture or dirt. In addition, the mass of the at least one cushioning element and, consequently, the manufacturing costs are reduced.
