Description

[0001] The invention relates to an additional module for an armrest element of a seat, in particular a vehicle seat. Furthermore, the invention relates to a vehicle seat with an armrest element.

[0002] Armrest elements of this type are used, for example, in commercial vehicles such as tractors, forklifts, construction equipment, and special-purpose vehicles. In such vehicles, the available space around the seat is often limited. Due to the lack of other storage options, there is a need to incorporate storage devices, holders, and similar features on the seat. Furthermore, it is desirable for various control and / or display devices to be mounted directly on the seat, as this minimizes relative movement between the occupant's hand and the control and / or display devices when the seat moves due to the road surface. Integrating such devices requires a wide variety of armrest designs, depending on customer requirements. This represents a significant undertaking for manufacturers.Furthermore, it may be desirable to retrofit existing vehicle seats or armrests with such features.

[0003] The object of the present invention is therefore to provide an armrest element which solves the problems mentioned above.

[0004] The problem is solved by an armrest element according to claim 1.

[0005] The core concept of the invention is an armrest element of a seat, in particular a vehicle seat, comprising a base body, wherein the armrest element has at least one first predefined connection interface to which an interchangeable extension module with a second predefined connection interface can be attached, wherein the first connection interface and the second connection interface are designed such that at least one positive-locking connection between the first connection interface and the second connection interface is enabled. Preferably, at least one positive-locking connection between the first connection interface and the second connection interface is provided.

[0006] A pre-defined first connection interface, compatible with a corresponding second pre-defined connection interface, allows for the attachment of a variety of extension modules to the armrest element. These extension modules simply require a second connection interface and can therefore be easily attached to the armrest. This results in a modular armrest adaptable to a wide range of applications. The connection between the first and second connection interfaces is direct, as the two interfaces are directly adjacent to each other.

[0007] Preferably, the armrest element extends along a longitudinal axis (X), a lateral axis (Y), and a vertical axis (Z). The armrest element is advantageously attachable to a seat. It is beneficial to provide a tilt adjustment device by means of which the tilt of the armrest relative to the seat can be adjusted. Accordingly, due to the adjustable tilt, the longitudinal axis and, optionally, the vertical axis of the armrest element can form an angle of inclination with the longitudinal axis and the vertical axis of the seat, respectively. The lateral axis of the armrest element can correspond to the lateral axis of the seat or form a preferably adjustable angle with it.

[0008] In an advantageous embodiment, the armrest element comprises a support element arranged on the base body. Advantageously, the base body is positioned along its vertical axis beneath the support element. Preferably, the support element comprises or is a cushioning element. However, it is also conceivable that the base body itself forms a support surface. The support surface or support element provides the occupant with a surface on which to rest their arm. An upper surface of the base body comprises the support surface or faces the support element. An underside of the base body faces the opposite upper surface.

[0009] Advantageously, a control element for adjusting the tilt of the armrest element is located on the underside of the base. This control element can be a rotatably mounted rotary knob or a cylindrical element.

[0010] Preferably, the base body comprises an outer longitudinal side extending along a longitudinal axis, a front side extending along a transverse axis, and a rear side extending along the transverse axis. The front side is spaced apart from the rear side along the longitudinal axis and is substantially opposite it. Advantageously, when the armrest element is installed, the rear side is closer to the backrest than the front side. The outer longitudinal side is spaced apart from an inner longitudinal side along the transverse axis and is substantially opposite it. The inner longitudinal side faces an occupant.

[0011] According to an advantageous embodiment, a first connection interface is arranged on the front side of the base body and / or on the rear side of the base body.

[0012] A positive-locking connection involves an effect achieved through the geometric contact of two surfaces. The connection may exhibit some play between these surfaces and allows one or more degrees of freedom. A positive-locking connection can also involve the use of a connecting element between the two elements being joined. Such a connecting element could be, for example, a screw, a pin, a rivet, or similar.

[0013] Advantageously, at least one of the positive-locking connections between the first and second connection interfaces is a detachable connection. This allows for the interchangeability of the expansion modules.

[0014] According to a further preferred embodiment, a first positive-locking connection in the form of a mate connection is provided between the first connection interface and the second connection interface. Preferably, the mate connection is as free of play as possible. Preferably, one of the connection interfaces comprises a receptacle in which a connecting section of the further connection interface is received. The connecting section and the receptacle are thus essentially complementary to each other. The term "essentially" is used here and throughout to account for tolerance deviations of the two elements, which, however, do not impair the function or the reception of the connecting element.

[0015] Advantageously, the first connection interface includes the connection section and the second connection interface the recording. However, it would also be conceivable for the second connection interface to include the connection section and the first connection interface the recording.

[0016] According to a further aspect of the invention, it is advantageous that at least a second positive-locking connection is provided between the first and second connection interfaces. Advantageously, the second positive-locking connection is a screw connection. However, other detachable positive-locking connections would also be conceivable.

[0017] Preferably, the receptacle of a connection interface and the connecting section of the further connection interface each have at least one first side wall. It is advantageous that the first side walls of the connection interfaces are abutting each other and each have aligned bores that enable the second positive-locking connection. Advantageously, the bores are equipped with an internal thread into which a screw can be screwed. Preferably, both the receptacle and the connecting section comprise two first side walls, which are spaced apart from each other along the width axis. Advantageously, one first side wall of the connecting section abuts a first side wall of the receptacle.The two adjacent first side walls, when the connecting section is inserted into the fixture, each have aligned bores that enable a second positive-locking connection. This allows for two-sided fixation of the extension module to the base body by means of two second positive-locking connections.

[0018] According to a further preferred embodiment, a guide connection is provided between the first and second connection interfaces, the guide connection comprising a pin element and a receptacle. Such a guide connection facilitates the placement of the extension module, as well as the base body or the second connection interface, onto the first connection interface. The engagement of the pin element in the receptacle aligns the extension module relative to the base body, so that in a final position the bores in at least one of the first side walls are aligned. A preferred screw can therefore be easily screwed in.

[0019] The guide connection is preferably arranged substantially centrally with respect to the extension of the first connection interface and the second connection interface along the width axis. Advantageously, the connection section and the receptacle each have a second side wall, which preferably extends substantially perpendicular to the first side walls. Advantageously, the second side wall connects the two first side walls. It would also be conceivable for the second side wall to be integrated into the base body or the extension module.

[0020] According to a further aspect of the invention, it is advantageous that the first connection interface and / or the second connection interface is provided on an adapter element which is arranged on the base body or the extension module. Preferably, the first connection interface is formed integrally or in one piece by the base body. Preferably, the second connection interface is formed integrally or in one piece by the extension module. Here and subsequently, an integral design is understood to mean that all sections are manufactured from a single, unified part.In this and the following, a one-piece design means that while all sections are not manufactured from a single, uniform part, they are not only firmly but so intimately connected that they do not appear as several joined components and, in any case, cannot be separated from one another without being destroyed. The advantageous one-piece or single-piece designs of the first and / or second connection interface described above offer the benefits of simple manufacturing and a stable or robust design for both the connection interfaces and the base body or extension module.

[0021] In a further advantageous embodiment, the first connection interface and / or the second connection interface is provided on an adapter element. Advantageously, the adapter element is arranged on the base body or the extension module. Preferably, the first connection interface is provided on an adapter element that is arranged on the base body. With such an advantageous adapter element, existing armrest elements or base bodies can be equipped with a first connection interface and thus extended with a multitude of possible extension modules. It would also be conceivable for the second connection interface to be provided on an adapter element that is arranged on an extension module. With such an advantageous adapter element, existing extension modules can be attached to a base body with a first connection interface.The aforementioned adapter elements can be attached to the base body or the extension module by means of a positive-locking or a material-locking connection. Screw connections, adhesive bonds, welded connections, and other suitable connections are all possible.

[0022] According to a further preferred aspect of the invention, the at least one expansion module is or comprises an active expansion module. Preferably, the active expansion module is selected from the group comprising: an input and / or output device, a joystick, a steering wheel, a push-button and / or switch element, a touchscreen, a display device, or combinations of the aforementioned elements. Of course, other similar active expansion modules are also conceivable. Thus, any input and / or output devices can be easily and mechanically arranged on the base body. It is advantageous that the base body includes connection options for the power supply and / or data lines for the respective active expansion module. Advantageously, the active expansion module can be arranged on the front of the base body.

[0023] According to a further advantageous embodiment, the at least one expansion module is or comprises a passive expansion module. Preferably, the passive expansion module is selected from the group comprising: a storage element, a mounting element (e.g., a cupholder), a hook element, a pocket, a net, an ashtray, an additional cushion, or combinations of the aforementioned elements. Of course, other similar passive expansion modules are also conceivable. Such passive expansion modules can be arranged on both the front and the rear of the base body.

[0024] According to a further aspect of the invention, it is advantageous that at least one further extension module can be arranged on the outer longitudinal side of the base body. Advantageously, the at least one further extension module is an active extension module, a passive extension module, or a combination of an active and a passive extension module. The active extension module can be selected from the group comprising: an input and / or output device, a joystick, a steering wheel, a touch and / or switching element, a touchscreen, a display device, or combinations of the aforementioned elements. Preferably, the passive extension module is selected from the group comprising: a storage element, a mounting element, a hook element, a pocket, a net, an ashtray, additional padding, or combinations of the aforementioned elements.Of course, other similar active or passive expansion modules are also conceivable.

[0025] According to a further preferred embodiment, a third predefined connection interface is provided, which is arranged on the outer longitudinal side of the base body and serves to attach the further expansion module. Preferably, the at least one further expansion module has a fourth predefined connection interface, which is compatible with the third connection interface.

[0026] According to a further preferred embodiment, the third connection interface comprises an adapter element with locking openings into which at least one locking projection of an extension module can engage. The adapter element can advantageously be designed as a multi-functional rail.

[0027] According to a further preferred embodiment, the additional extension module is a net storage element. The net can advantageously be elastic. Preferably, the net storage element is arranged on the base body by means of at least one positive-locking connection. Preferably, the positive-locking connection is a screw connection.

[0028] According to a further preferred embodiment, the at least one expansion module and / or the at least one further expansion module is configured such that at least one additional expansion module can be attached to it. The at least one expansion module and / or the at least one further expansion module are or comprise a fifth connection interface. The fifth connection interface is thus an indirect interface. The additional expansion module can preferably be attached to the at least one expansion module or the at least one further expansion module by means of a force-fit connection. The fifth connection interface can, for example, represent at least one opening, at least one projection, or the like, in or on which clamping devices of the additional expansion module can engage.However, such an opening could also be an opening for a passive expansion module, such as a storage element or cupholder. Such an additional expansion module could, for example, be a holder for a smartphone or mobile phone.

[0029] The task is also accomplished by a vehicle seat with an armrest element. The vehicle seat can be equipped with all the features already described above in relation to the armrest element, either individually or in combination, and vice versa.

[0032] In the figures, identical components are to be understood by their corresponding reference symbols. For clarity, some components may not be labeled with a reference symbol in certain figures, but are identified elsewhere.

[0033] The Fig. 1 to Fig. Figure 8e shows an armrest element 1 of a seat, in particular a vehicle seat 100, with a base body 2, wherein the armrest element 1 has at least one first predefined connection interface 3, to which an interchangeable extension module 4 can be fixed with a second predefined connection interface 5, wherein the first connection interface 3 and the second connection interface 5 are designed such that at least one positive-locking connection between the first connection interface 3 and the second connection interface 5 is enabled. At least one positive-locking connection between the first connection interface 3 and the second connection interface 5 is provided. A plurality of different extension modules 4 can be arranged on the armrest element 1 by means of such a predefined, preferably even standardized, connection interface.

[0034] The armrest element 1 extends along a longitudinal axis X, a width axis Y, and a height axis Z. The armrest element 1 can be arranged on a seat 100. This is in Fig. Figure 10 shows a fastening element 29, which is attached to the base body 2. A tilt adjustment device may be provided, by means of which the tilt of the armrest element 1 relative to the seat 100 can be adjusted. The tilt adjustment device is operated by a control element 30, in the form of a rotatably arranged cylindrical element. This control element 30 is arranged on a lower surface 2b of the base body 2. The base body 2 has a recess 31 for this purpose.

[0035] In an advantageous embodiment, the armrest element 1 comprises a support element 32, which is arranged on the base body 2. The base body 2 is arranged along the vertical axis Z beneath the support element 32. The support element 32 comprises, or is itself a cushioning element. The support element 32 provides the occupant with a surface on which to rest their arm. An upper surface 2a of the base body 2 faces the support element 32. The lower surface 2b of the base body 2 faces the upper surface 2a. The base body 2 comprises a lower section from which side walls 11 extend along the vertical axis Z. The upper surface 2a of the base body 2 is open and is covered by the support element 32.

[0036] The basic body 2 comprises an outer longitudinal side 6 extending along a longitudinal axis X. The outer longitudinal side 6 is spaced along the transverse axis Y from an inner longitudinal side 6a and is substantially opposite it. The inner longitudinal side 6a faces an occupant. Furthermore, the basic body 2 comprises a front side 7 extending along the transverse axis Y and a rear side 8 extending along the transverse axis Y. The front side 7 is spaced from the rear side 8 along the longitudinal axis X and is substantially opposite it.

[0037] According to the embodiments shown in the figures, a first connection interface 3 is provided both on the front side 7 of the base body 2 and on the rear side 8 of the base body 2. Of course, embodiments are also conceivable in which the first connection interface 3 is provided on the front side 7 of the base body 2 or on the rear side 8 of the base body 2.

[0038] A first positive-locking connection in the form of a mate connection is provided between the first connection interface 3 and the second connection interface 5. The mate connection comprises connection interfaces 3, 5 configured as a receptacle 9. In the illustrated embodiments, the second connection interface 5 is configured as a receptacle 9. Furthermore, the first connection interface 3 is configured as a connecting section 10. The connecting section 10 can be inserted into the receptacle 9 and is received by it. The first connection interface 3 and the second connection interface 5 are thus compatible.

[0039] The first connection interface 3 is formed in one piece or integrally by the base body 2. Likewise, the second connection interface 5 is formed in one piece or integrally by the extension module 4. However, it is also conceivable that the first connection interface 3 and / or the second connection interface 5 are provided on an adapter element 37. The adapter element 37 could then be arranged on the base body 2 or the extension module 4.

[0040] At a first connection interface 3, which is located on the front face 7 of the base body 2, the connection section 10 is essentially rectangular. Of course, other shapes such as a triangle or any other polygonal shape would also be conceivable. The connection section 10 comprises two first side walls 11 spaced apart along the width axis Y, which extend along the length axis X and the height axis Z. A second side wall 33, which extends essentially along the width axis Y and the height axis Z, connects the two first side walls 11. The two first side walls 11 and the second side wall 33 are arranged on a plate-like element 42, or are formed integrally with it.

[0041] In a second connection interface 5 compatible with this first connection interface 3, the receptacle 9 is also essentially rectangular and comprises two first side walls 11 extending along the longitudinal axis X and the vertical axis Z. Furthermore, a second side wall 33 integrated into the extension module 4 is provided (not visible in the views), extending along the width axis Y and the vertical axis Z and connecting the two first side walls 11. The receptacle 9 also includes the receptacle on which at least the two first side walls 11, and preferably also the second side wall 33, are arranged, or are formed integrally or in one piece with it.

[0042] Furthermore, a guide connection 13 is provided between the first connection interface 3 and the second connection interface 5. This guide connection 13 comprises a pin element 14 and a receptacle 15. At the first connection interface 3, which is located on the front face 7 of the base body 2, the receptacle 15 is located in the second side wall 33 of the connection section 10. The receptacle 15 is located essentially centrally along the width axis Y. The pin element 14 is located on the second side wall 33 of the second connection interface 5.

[0043] When the extension module 4 is slid onto the base body 5, the connecting section 10 enters the receptacle 9. The guide connection 13 positions the connecting section 10 correctly relative to the receptacle 9. The guide connection 13 thus facilitates the assembly of a corresponding extension module 4. In one end position, the plate-like element 42 of the connecting section 10 rests against the plate-like element 42 of the receptacle 9, with the plate-like element 42 of the connecting section 10 lying above the plate-like element 42 of the receptacle 9 along the vertical axis Z. Furthermore, the first side walls 11 of the connecting section 10 rest against the first side walls 11 of the receptacle 9, with the first side walls 11 of the connecting section 10 lying within (i.e., closer to an imaginary center line) the first side walls 11 of the receptacle 9 along the horizontal axis Y.The first side walls 11 of the connecting section 10 and the first side walls 11 of the receptacle 9 each have aligned bores 12, which enable the second positive-locking connection. These bores 12 are preferably threaded so that a screw can be inserted. This second positive-locking connection secures the extension module 4 to the base body 2.

[0044] Among other things from the Fig. Figure 1 shows that the first side walls 11 of the connecting section 10 and the receiver 9 have a curved profile along the vertical axis Z. When the extension module 4 is attached to the base body 2, a kind of recess is thus present into which the downwardly extending section of the support element 32 can be inserted.

[0045] A first connection interface 3, which is provided on the rear side 8 of the base body 2, is designed as a connection section 10. The connection section 10 comprises first side walls 11, which are integrated into the base body 2. The compatible second connection interfaces 5 also comprise first side walls 11. These side walls 11 extend forward along the longitudinal axis X. The receptacle 9 is essentially trapezoidal or parabolic in shape. Here, too, the first side walls 11 of the receptacle 9 encompass the first side walls 11 of the connection section 10 when the extension module 4 is guided onto the base body 2. A guide connection 13 with a pin element 14 (in Fig. (see Figure 6e) and a receptacle 15, wherein the pin element 14 is arranged in the second connection interface 5 designed as a receptacle 15. For the connection interfaces 3, 5 provided for the rear 8, it can be advantageous that only one opposing pair of first side walls 11 has a bore 12 for a second positive-locking connection. These side walls 11 face the outer longitudinal side 6. A screw can be conveniently screwed in here. The other pair of opposing side walls 11 faces the inner longitudinal side 6a. Here, in the case of an armrest element 1 mounted on a seat 100, the backrest can make it difficult to insert or loosen a screw.

[0046] Furthermore, at least one additional extension module 24 can be arranged on the outer longitudinal side 6 of the base body 2.

[0047] At least one expansion module 4 can be an active expansion module 4, a passive expansion module 4, or a combination of an active and a passive expansion module 4. At least one further expansion module 24 can also be an active expansion module 24, a passive expansion module 24, or a combination of an active and a passive expansion module 24.

[0048] An active expansion module 4, 24 can be an input and / or output device 16, a joystick 17, a steering wheel, a touch and / or switch element 23, a touchscreen 18, a display device 19, or a combination of the aforementioned elements. A passive expansion module 4, 24 can be a storage element 20, a mounting element 21, for example, a cupholder, a hook element 22, a pocket, a net, an ashtray, an additional cushion, or combinations of the aforementioned elements. Fig. Figure 1 shows some of these active and passive expansion modules 4, 24.

[0049] For attaching the further extension module 24 to the outer longitudinal side 6 of the base body 2, a third predefined connection interface 25 is provided, which is arranged or formed on the outer longitudinal side 6 of the base body 2. The at least one further extension module 24 comprises a fourth predefined connection interface 26, which is compatible with the third connection interface 25.

[0050] The third connection interface 25 can be a single section 34 of a side wall of the base body 2. This side wall 34 has at least one, preferably two, and more preferably three bores 36. These bores 36 are preferably threaded. A fourth connection interface 26 has a side wall 35 compatible with the section 34 of a side wall of the base body 2. This side wall 35 also has corresponding bores 36 which, when the further extension module 24 is arranged on the base body 2, align with the bores 36 of the base body 2, so that at least one positive-locking connection, preferably a screw connection, can be established. An extension module 24 that can be arranged in this way is, for example, a mesh storage element 27. This is in Fig. 1 and in the Fig. 4a to Fig. 4e is evident.

[0051] The third connection interface 25 can further comprise an adapter element 37, which can be designed as a multi-function strip. The adapter element 37 comprises a plurality of locking openings 38 into which at least one locking projection 39 can engage. This is shown in the Fig. 9b clearly visible. The adapter element 37 can be attached to the base body 2 using at least one bore 36, preferably two bores 36, more preferably three bores 36.

[0052] The at least one expansion module 4 and / or the at least one further expansion module 24 is designed such that at least one additional expansion module 28 can be attached to it. For this purpose, openings and / or projections may be provided, which, for example, enable a force-fit connection, such as a clamping connection, with an additional expansion module 28. The at least one expansion module 4 and / or the at least one further expansion module 24 are therefore, or include, a fifth connection interface 40. Thus, many common additional expansion modules 28 can be indirectly attached to the base body 2 by means of a force-fit connection. Fig. Figure 2d shows, for example, an additional extension module 28 in the form of a holder for a smartphone. This holder is arranged in an extension module 4 in the form of a mounting element / cupholder 21 by means of a clamping connection against the inner wall of the mounting element / cupholder 21.

[0053] In Fig. Figure 1 shows an extension module 4, which is designed as an adapter module 41. The adapter module 41 comprises an end face with various bores 12, which are equipped with an internal thread. Various other elements can be attached to the adapter module 41 by means of these bores 12.

[0054] In the Fig. 2a to Fig. Figure 8e shows different combinations of extension modules 4 and further extension modules 24 in different views.
