Description

Technical Field

[0001] This disclosure relates to the field of transportation technology, and more specifically to a slide rail assembly, a slide rail device, a combined slide rail assembly for a transportation vehicle, an interior trim assembly for a transportation vehicle, and a transportation vehicle. Background Technology

[0002] Large SUVs and MPVs typically feature three rows of seats, with the first and second rows requiring forward and backward movement. Existing technologies offer corresponding solutions for this usage scenario.

[0003] In conventional seat slide rails, two lower slide rails are typically used for a row of seats. Each seat is connected to two upper slide rail components, each driven by a corresponding motor. Because the gap between the two sets of slide rails is relatively large in traditional designs, such as approximately 400mm, a synchronization module is needed to ensure the synchronicity of the left and right motors and the upper slide rails when the two upper slide rail components corresponding to the same seat are driven by two independent motors. Otherwise, there is a risk of malfunction or jamming, leading to high system costs. Furthermore, existing technologies also include a single motor placed between the two lower slide rails, which is connected to two upper slide rail components respectively mounted on the two lower slide rails via a transmission mechanism, thereby driving the upper slide rail components to move. In this solution, the arrangement and construction of the transmission mechanism are also relatively complex.

[0004] In other existing seat slide rails, the opening width of the two slide rails mentioned above is also relatively large, which leads to the need to set up a motor for each upper slide rail component. Utility Model Content

[0005] The purpose of this disclosure is to provide a lower slide rail assembly that ensures that all upper slide rail components in a corresponding upper slide rail assembly, which can be mounted on at least two lower slide rails, can be moved without jamming or asynchronous movement by a driver located on the lower slide rail.

[0006] Another object of this disclosure is to provide a slide rail device, a combined slide rail assembly for a vehicle, an interior trim assembly for a vehicle, and a vehicle.

[0007] To achieve the above objectives, a first aspect of this disclosure relates to a lower slide rail assembly, characterized in that the lower slide rail assembly includes at least two lower slide rails, each of the at least two lower slide rails being arranged relative to each other in the lateral direction such that a driver disposed on the lower slide rail can drive all upper slide rail components disposed on the at least two lower slide rails to move without causing the corresponding upper slide rail components to jam at the lower slide rail or to cause asynchronous movement.

[0008] In this disclosure, the opening width of the lower slide rail affects the synchronization of the upper slide rail components when one motor is used for two upper slide rail components (one-to-two). If the opening width is too large, such as approximately 400mm in the prior art, a motor is required to drive one upper slide rail component. Therefore, in this disclosure, by arranging the lower slide rails relative to each other in the lateral direction, it is possible to ensure that no jamming or asynchrony occurs while using a single driver to move the corresponding upper slide rail components. This effectively solves the problem in the prior art where a large opening width between the two lower slide rails necessitates a separate motor for each upper slide rail component or a complex transmission mechanism for a single motor. This saves one motor or eliminates the need for a complex transmission mechanism compared to the prior art, thereby saving costs or simplifying control.

[0009] In some embodiments, at least some or all of the at least two sliding rails are arranged adjacent to each other. This ensures a small opening width for the sliding rails and eliminates the risk of malfunction or jamming.

[0010] In some implementations, the opening width of the at least two lower slide rails is at most five times the width of one lower slide rail. This ensures a smaller opening width for the lower slide rails and eliminates the risk of malfunction or jamming.

[0011] In some implementations, the opening width of the at least two lower slide rails is at most four times the width of one lower slide rail. This better ensures that the opening width of the lower slide rails is small, and thus eliminates the risk of inoperability or jamming.

[0012] In some implementations, the opening width of the at least two lower slide rails is at most three times the width of one lower slide rail. This ensures a particularly good small opening width for the lower slide rails, and thus eliminates the risk of inoperability or jamming.

[0013] In some embodiments, at least some or all of the at least two sliding rails are arranged adjacent to each other. This allows for an advantageous relative arrangement of the at least two sliding rails. Consequently, a small opening width for the sliding rails is largely ensured, and the risk of inoperability or jamming is eliminated. Furthermore, the adjacent arrangement of these sliding rails facilitates their placement.

[0014] In some embodiments, the at least two lower rails are integrally constructed and form a single lower rail assembly. Therefore, by constructing each lower rail component in the lower rail assembly as a single unit, a smaller opening width can be achieved. Furthermore, the integral construction of the lower rail assembly is advantageous for the arrangement of the lower rails in the transport vehicle. In the prior art, two separately arranged lower rails require considerable effort to ensure their parallelism. In contrast, in this disclosure, due to the integral construction of the lower rail assembly, the parallelism of each lower rail can be easily ensured without additional effort. In some embodiments, the lower rail assembly is manufactured by integral extrusion molding. This allows for advantageous manufacturing of the lower rail assembly.

[0015] In some embodiments, the at least two sliding rails are each formed separately and, when joined together, form a sliding rail assembly through form-locking and / or material-locking and / or force-locking. Therefore, in addition to one-piece molding, it is conceivable to form them separately and then join them together. This combination method is more flexible than one-piece molding of multi-rail sliding rail assemblies. In this disclosure, form-locking can be understood as constraint through geometry, such as connection through snap-fit ​​or mortise-and-tenon structures. Material-locking can be understood as connection achieved through physical or chemical action of materials, such as welding or gluing. Force-locking connection can be understood as connection through friction or preload, such as bolted connections.

[0016] In some embodiments, two adjacent lower slide rails are constructed as grooves and share a groove wall between them. This achieves an advantageous integrated lower slide rail construction.

[0017] In some implementations, at least three lower slide rails are provided. This allows for more complex application scenarios. Existing technologies typically only use two lower slide rails, which limits the range of applications.

[0018] In some implementations, the lower rail assembly is used in a transportation vehicle.

[0019] The second aspect of this disclosure relates to a slide rail device, characterized in that the slide rail device includes a lower slide rail assembly according to this disclosure and at least two upper slide rail assemblies movable at the lower slide rail, each upper slide rail assembly having a travel portion for its own use and coupled to the corresponding upper slide rail assembly, and each travel portion being configured to limit the travel of the upper slide rail assembly coupled thereto.

[0020] In this disclosure, a "stroke section" can be understood as a structure that limits the travel distance. It can be formed, for example, by a stroke member constructed as a lead screw as described below, or by a portion of a sliding rail. For example, the lead screw or sliding rail can cooperate with a stop point to define the stroke section. It should also be noted that a stroke member can form only one stroke section, or it can cooperate with virtual stop points to form multiple stroke sections.

[0021] In some embodiments, the upper slide rail assembly itself includes a first upper slide rail component and a second upper slide rail component, wherein the first upper slide rail component and the second upper slide rail component are respectively disposed at any two of the at least two lower slide rails.

[0022] In some embodiments, the first upper slide rail component and the second upper slide rail component are respectively disposed at the two outermost lower slide rails of the at least two lower slide rails. This maximizes the stable operation of the interior trim or other track devices fixed to the first and second upper slide rail components.

[0023] In some implementations, each upper slide rail assembly is equipped with only one driver, which works in conjunction with the travel section of the corresponding upper slide rail assembly to move each upper slide rail component of the corresponding upper slide rail assembly. Thus, each upper slide rail assembly can be moved using only one driver. Compared to the prior art where a separate motor is used for each of the two upper slide rail components in an upper slide rail assembly, no additional module is needed to control the synchronization of the various upper slide rail components within the same upper slide rail assembly, and the number of motors is reduced, thereby lowering costs.

[0024] In some embodiments, a first upper slide rail assembly-stroke section configuration is provided. In this configuration, one of the first and second upper slide rail components is positioned in a lower slide rail with a stroke section that mates with the corresponding upper slide rail assembly, while the other upper slide rail component is positioned in a lower slide rail without a corresponding stroke section. Thus, for a given upper slide rail assembly, one upper slide rail component can move on the corresponding lower slide rail via a driver and a stroke section that mates with the driver, while the other upper slide rail component can act as a driven rail. This eliminates the need for module control of the synchronization of the various upper slide rail components within the same upper slide rail assembly.

[0025] In some implementations, the driver is disposed on the upper slide rail component.

[0026] In some embodiments, a second upper slide rail assembly-stroke section configuration is provided. This configuration includes at least three lower slide rails, with the stroke section corresponding to each upper slide rail assembly located on the lower slide rail between the first and second upper slide rail components. Thus, both upper slide rail components can function as driven rails. This configuration also allows for synchronization of the various upper slide rail components within the same upper slide rail assembly without requiring a synchronization module for control.

[0027] In some embodiments, a third upper slide rail component is provided at the lower slide rail having a travel portion that mates with the corresponding upper slide rail assembly. The third upper slide rail component is located between the first upper slide rail component and the second upper slide rail component, and the driver is disposed on the third upper slide rail component. This achieves an advantageous arrangement of the driver for the second upper slide rail assembly-travel portion configuration.

[0028] In some embodiments, a support member is provided, which is laterally mounted on each upper slide rail component in the same upper slide rail assembly to connect the upper slide rail components in the same upper slide rail assembly. This allows for synchronous operation of the upper slide rail components in the same upper slide rail assembly using a simple, laterally mounted support member. In this disclosure, because the lower slide rail assembly has an integral construction, the distance between the first and second upper slide rail components can be small. Furthermore, the small span of the support member allows for a simple structural design that can meet stiffness requirements (such as bending stiffness).

[0029] In some embodiments, the actuator is mounted on the support member. This allows for another advantageous arrangement of the actuator for the second upper slide rail assembly – the travel section.

[0030] In some embodiments, the slide rail device includes a travel member disposed at the lower slide rail, the travel portion being formed by the travel member; or the travel portion being formed by a portion of the lower slide rail. When the travel portion is formed by the travel member, it provides the possibility of electric movement of the upper slide rail assembly; while when the travel portion is formed by a portion of the lower slide rail, it provides the possibility of manual movement of the upper slide rail assembly.

[0031] In some embodiments, the travel portion is limited by a stop point, which is either a physical stop point set on the travel member or the lower slide rail, or a virtual stop point set by a controller for the slide rail device along the travel member or the lower slide rail.

[0032] In some implementations, the number of lower slide rails is the same as the number of upper slide rail assemblies, or the number of lower slide rails is less than the number of upper slide rail assemblies.

[0033] A third aspect of this disclosure relates to a modular slide rail assembly for a transport vehicle, characterized in that the modular slide rail assembly includes a first slide rail device and a second slide rail device. The first slide rail device extends along the longitudinal direction of the transport vehicle, while the second slide rail device extends along the transverse direction of the transport vehicle and is arranged on the first slide rail device and is movable along the longitudinal direction of the transport vehicle via the first slide rail device. The first slide rail device is a slide rail device according to this disclosure, and / or the second slide rail device is a slide rail device according to this disclosure. This allows for a crisscrossing modular slide rail assembly, enabling more diverse arrangement of the slide rail devices within the transport vehicle. Furthermore, for this disclosure, when the lower slide rail assembly in the slide rail device is integrally constructed, the lower slide rail assembly can be constructed as a single piece, making arrangement very convenient. In particular, the arrangement of the second slide rail device can be very conveniently placed on the first slide rail device.

[0034] In some embodiments, two first slide rail devices are provided, arranged parallel to each other. This allows for a more stable arrangement of the second slide rail device on the first slide rail device. Furthermore, these two first slide rail devices can also be used, as commonly seen, for the forward and backward movement of interior trim components, such as seats.

[0035] A fourth aspect of this disclosure relates to a combined slide rail assembly for a transport vehicle, characterized in that the interior trim assembly includes interior trim and a slide rail device according to this disclosure or a combined slide rail assembly for a transport vehicle according to this disclosure, wherein the interior trim is mounted on a corresponding upper slide rail assembly of the slide rail device or on a corresponding upper slide rail assembly of the second slide rail device to enable movement.

[0036] In some embodiments, the slide rail device extends along the longitudinal direction of the transport vehicle; or the slide rail device extends along the transverse direction of the transport vehicle.

[0037] In some embodiments, the interior trim is a seat or a footrest or leg rest for supporting the occupant's feet or legs. Thus, unlike existing technologies, the interior trim is not limited to seats but can also be footrests or leg rests, providing a wider range of application scenarios for the corresponding sliding rail devices.

[0038] The fifth aspect of this disclosure relates to a means of transport that includes a slide rail device according to this disclosure, or includes a combined slide rail assembly for a means of transport according to this disclosure, or includes an interior trim assembly for a means of transport according to this disclosure.

[0039] The technical features mentioned above, those to be mentioned below, and those shown individually in the accompanying drawings can be combined arbitrarily, provided that the combined technical features are not contradictory. All feasible combinations of features are the technical content explicitly described herein. Any one of the multiple sub-features contained in the same statement can be applied independently, without necessarily being applied together with other sub-features. Attached Figure Description

[0048] Firstly, by using Figures 1 to 4 A first embodiment of the slide rail device according to the present disclosure is described.

[0049] The slide rail device 100 disclosed herein can be used in a transport vehicle 200 (see...) Figure 7 The vehicle 200 can be used in various applications, including transportation vehicles, such as passenger cars. The vehicle 200 can also be other land-based transportation vehicles, air-based transportation vehicles, or water-based transportation vehicles. For passenger cars, the vehicle 200 disclosed herein is particularly suitable for mid-to-large-sized SUVs or MPVs. Of course, the slide rail device 100 of this disclosure can also be used in other applications requiring slide rails, in addition to its use in transportation vehicles 200.

[0050] In such Figures 1 to 4 In the illustrated slide rail device, multiple, such as three, integrally formed lower slide rails 1 are provided, which constitute a single lower slide rail assembly. The lower slide rail 1 can be constructed as a groove. Of course, other forms of lower slide rails are also conceivable.

[0051] Multiple rows of upper slide rail components are installed within each lower slide rail 1. Each row of upper slide rail components forms an upper slide rail assembly 2, and these upper slide rail assemblies 2 are arranged sequentially along the moving direction of the upper slide rail components, or in other words, along the axial direction of the lower slide rail 1. Multiple upper slide rail components in each upper slide rail assembly 2 are respectively disposed within multiple parallel lower slide rails 1. Figures 1 to 4 The slide rail device scheme shown can also be called a multi-row common rail scheme.

[0052] For each upper slide rail assembly 2, it can be as follows: Figure 1 and Figure 2As clearly seen, a single motor is provided as the driver 5, which can drive the corresponding upper slide rail assembly 2 to move. For each upper slide rail assembly 2, a single lead screw is provided as a travel member 4, which forms a travel section 3 for the upper slide rail assembly 2. Besides the lead screw, a rack can also be considered as the travel member 4, with a gear directly or indirectly connected to the driver 5 engaging with the rack. In this embodiment, one travel member 4 forms one travel section 3. The lead screw, as the travel member 4, is fixedly installed in the groove of the corresponding lower slide rail 1, and transmission is achieved through engagement with the lead screw nut in the gearbox, so as to cover the travel stroke of the upper slide rail assembly 2 equipped with the motor via the travel section 3. Therefore, in the first embodiment, a slide rail device 100 is provided, which includes three lower slide rails 1 and three upper slide rail assemblies 2 movable at the lower slide rails 1. Each upper slide rail assembly 2 is provided with a travel portion 3 for its own use and which is coupled to the corresponding upper slide rail assembly 2. Each travel portion 3 is configured to limit the travel of the upper slide rail assembly 2 coupled to it. Each travel portion 3 is constructed and arranged such that there is an overlap between the travel of any two adjacent travel portions 3 for different upper slide rail assemblies 2. Each lower slide rail 1 is provided with only one lead screw as a travel member 4, and this one travel member 4 forms a travel portion 3.

[0053] Each upper slide rail assembly 2 includes a first upper slide rail component 21 and a second upper slide rail component 22, which are respectively disposed at the two outermost lower slide rails 1 of the three lower slide rails 1. Alternatively, the first upper slide rail component 21 and the second upper slide rail component 22 can be disposed at two directly adjacent lower slide rails 1. The primary purpose of providing at least the first upper slide rail component 21 and the second upper slide rail component 22 is to ensure the stable movement of the interior trim pieces mounted upon them.

[0054] For ease of description, the three upper slide rail assemblies 2 are referred to as the front row upper slide rail assembly 2a, the middle row upper slide rail assembly 2b, and the rear row upper slide rail assembly 2c from front to back; and the three lower slide rails 1 are referred to as the first lower slide rail 1a, the second lower slide rail 1b, and the third lower slide rail 1c from front to back.

[0055] For example Figure 1 and Figure 2 Regarding the front upper slide rail assembly 2a and the rear upper slide rail assembly 2c shown, a motor as a driver 5 is mounted on one upper slide rail component, which is disposed in a lower slide rail 1 having a stroke portion 3 that matches the corresponding upper slide rail assembly 2. The other upper slide rail component is a driven rail, and its corresponding lower slide rail 1 does not have a stroke portion 3. This configuration can be referred to as a first upper slide rail assembly-stroke portion configuration. Figure 1and Figure 2 In the embodiment shown, the first upper slide rail component 21 and the second upper slide rail component 22 are respectively disposed on the outermost side of the two lower slide rails 1 in order to achieve more stable movement of the interior trim parts placed on the two upper slide rail components. However, it is also conceivable that one of the upper slide rail components is not disposed on the outermost lower slide rail 1, but is disposed on the middle lower slide rail 1.

[0056] For the middle row upper slide rail assembly 2b, the stroke portion 3, which is matched with the corresponding upper slide rail assembly 2, is located between the first upper slide rail component 21 and the second upper slide rail component 22. This configuration can be referred to as the second upper slide rail assembly-stroke portion configuration. In the first embodiment, under the second upper slide rail assembly-stroke portion configuration, the first upper slide rail component 21 and the second upper slide rail component 22 of the middle row upper slide rail assembly 2b are located at the outer first lower slide rail 1a and the third lower slide rail 1c, while the corresponding stroke portion 3 is located in the middle second lower slide rail 1b. The motor corresponding to the stroke portion 3 is located on the third upper slide rail component 23, which can move on the middle second lower slide rail 1b. The upper slide rail components of the middle row upper slide rail assembly 2b are connected to each other by a bracket 6, such as a bracket plate, to achieve synchronized movement. In another embodiment, the upper slide rail components can also be connected together to the interior trim, such as the seat 201 or the leg rest 202 (see...). Figure 7 The movement of each upper slide rail component in the same upper slide rail assembly 2 is synchronized on the skeleton of the upper slide rail assembly 2.

[0057] Specifically, in the front row upper slide rail assembly 2a, each upper slide rail component is arranged horizontally side-by-side in the first lower slide rail 1a and the third lower slide rail 1c. The motor is directly mounted on the first upper slide rail component 21 within the first lower slide rail 1a, and the lead screw forming the corresponding stroke portion 3 is mounted within the first lower slide rail 1a. The two upper slide rail components are connected together to the interior trim, such as the frame of the seat 201. In the middle row upper slide rail assembly 2b, each upper slide rail component is arranged horizontally side-by-side in the first lower slide rail 1a, the second lower slide rail 1b, and the third lower slide rail 1c. The motor is mounted on the third upper slide rail component 23 within the second lower slide rail 1b, and the lead screw forming the corresponding stroke portion 3 is mounted within the second lower slide rail 1b. A bracket 6 is horizontally mounted at the first, second, and third upper slide rail components 21, 22, and 23 to connect each upper slide rail component. The upper slide rail components of the rear row upper slide rail assembly 2c are arranged laterally side-by-side in the first lower slide rail 1a and the third lower slide rail 1c. The motor is directly mounted on the second upper slide rail component 22 within the third lower slide rail 1c, and the lead screw forming the corresponding stroke section 3 is mounted within the third lower slide rail 1c. The two upper slide rail components are connected together to the interior trim, such as the frame of the seat 201. For these three rows of upper slide rail assemblies 2, the front row upper slide rail assembly 2a and the rear row upper slide rail assembly 2c adopt the first upper slide rail assembly-stroke section configuration; while the middle row upper slide rail assembly 2b adopts the second upper slide rail assembly-stroke section configuration. Figure 1 and Figure 2 In the illustrated embodiment, the middle row upper slide rail assembly 2b adopts a second upper slide rail assembly-stroke section configuration because the stroke section 3, which is matched with the corresponding upper slide rail assembly 2, is located between the first upper slide rail component 21 and the second upper slide rail component 22. Furthermore, a third upper slide rail component 23 is provided to facilitate motor placement. Alternatively, the middle row upper slide rail assembly 2b can also adopt a first upper slide rail assembly-stroke section configuration. In this case, one of the first upper slide rail component 21 and the second upper slide rail component 22 is located at the middle second lower slide rail 1b, while the other is located at either the first lower slide rail 1a or the third lower slide rail 1c, thus forming a first upper slide rail assembly-stroke section configuration, and eliminating the need for an additional third upper slide rail component 23. Furthermore, it is conceivable that the middle row upper slide rail assembly 2b does not have a third upper slide rail component 23 at the second lower slide rail 1b, but instead only has a motor and gearbox. The motor and gearbox are fixedly connected to the bracket 6, and the lead screw nut in the gearbox is connected to the lead screw drive in the second lower slide rail 1b. Therefore, for the second upper slide rail assembly - stroke section configuration, it is possible to place the third upper slide rail component 23 at the middle lower slide rail 1 with the lead screw and install the motor on the third upper slide rail component 23. In this case, in order to synchronize the movement of the three upper slide rail components in the same upper slide rail assembly 2, it is possible to set up the bracket 6 connecting the three upper slide rail components in the same upper slide rail assembly 2; otherwise, it is possible to eliminate the third upper slide rail component 23 and directly set the motor and gearbox on the bracket 6.

[0058] In the first embodiment, as described above, the three sliding rails 1 are integrally formed. However, it should be noted that the integrally formed three sliding rails 1 is a preferred embodiment. The purpose of integral forming is to obtain a particularly small opening width W (e.g., ...) of the sliding rail assembly composed of the three sliding rails 1. Figure 4 (As shown). When the opening width W is small, jamming or asynchronous movement can be avoided when two or three upper slide rail components are moved by a single motor. Therefore, it is also conceivable that the three lower slide rails 1 are spaced apart from each other. In some embodiments, the opening width W of the at least two lower slide rails 1 is at most five times, preferably four times, and more preferably three times the width of one lower slide rail 1. Here, the opening width W is the lateral distance between the centers of the two outermost lower slide rails 1. It is important here that the lower slide rails 1 are arranged relative to each other in the lateral direction such that a single motor can drive all the upper slide rail components of the corresponding upper slide rail assembly 2 to move without causing the corresponding upper slide rail assembly 2 to jam at the lower slide rail 1 or cause asynchronous movement. Here, the "lateral direction" for each lower slide rail 1 refers to the direction oriented transversely to the axial direction of the lower slide rail 1.

[0059] In the first embodiment, any two adjacent sliding rails 1 are directly adjacent to each other, and share a common groove wall 9 between the two sliding rails 1 (e.g., Figure 3 (As shown). In addition, the lower rail assembly is manufactured by integral extrusion molding.

[0060] Besides integral molding, it is also conceivable that the three sliding rails 1 can be molded separately and, when spliced ​​together, form a sliding rail assembly through additional fixing means. In this disclosure, such fixing means can be form-locking and / or material-locking and / or force-locking. The forms of form-locking, material-locking, and force-locking are described above.

[0061] Next, using Figure 5 and Figure 6 The arrangement structure of the slide rail 1 according to the second and third embodiments of the slide rail device 100 of this disclosure is shown. Figure 5 In this configuration, the three sliding guide rails 1 are all arranged spaced apart from each other or adjacent to each other. The opening width W of these sliding guide rails 1 is three times the width of a single sliding guide rail 1. Figure 6 In the three lower slide rails 1, two lower slide rails 1 are arranged close to each other, while two lower slide rails 1 are arranged adjacent to each other. Figure 5 and Figure 6 Both arrangement structures allow a single driver 5 to move all upper slide rail components in the corresponding upper slide rail assembly 2 without causing the upper slide rail assembly 2 to jam at the lower slide rail 1 or resulting in asynchronous movement. Besides Figure 5 and Figure 6 Besides the sliding track 1 arrangement shown, other feasible sliding track 1 arrangements can also be conceived.

[0062] The slide rail device 100 disclosed herein can be arranged not only along the longitudinal direction of the transport vehicle 200 as is usually the case, but also along the transverse direction of the transport vehicle 200. Interior components, such as a seat 201, leg rest 202, or footrest, can be installed on the slide rail device 100. The seat 201 may be, for example, a zero-gravity seat.

[0063] This section describes an interior component assembly for a passenger vehicle, using a passenger car as an example. This interior component assembly can be as follows: Figure 7The diagram shows two longitudinally extending slide rail assemblies 100 and interior trim arranged on the slide rail assemblies 100. For example, this passenger vehicle is a large four-seater, where the front interior trim can be a driver's seat 201 and a front passenger seat 201, the middle interior trim can be two leg rests 202, and the rear interior trim can be two seats 201, particularly zero-gravity seats. In the slide rail assembly 100 of this disclosure, the lower slide rail assembly includes at least two lower slide rails 1, each of which is arranged relative to each other in the lateral direction such that a driver 5 located at the lower slide rail can move all the upper slide rail components of the corresponding upper slide rail assemblies 2 disposed on the at least two lower slide rails 1 without causing the corresponding upper slide rail assemblies 2 to jam at the lower slide rail 1 or to exhibit asynchronous movement. In this case, the opening width W of the lower slide rail assembly is small, which is beneficial for the arrangement of the slide rail assembly 100 in the vehicle 200. In particular, in the slide rail device 100 of this disclosure, when each of the slide rails 1 in the slide rail assembly 2 is arranged adjacent to each other, the slide rail device 100 can be arranged very conveniently at the assembly site.

[0064] also, Figure 8 As shown, the slide rail devices 100 can also be combined to form a modular slide rail assembly. Again, taking a passenger car as an example, another interior trim assembly for a passenger car is described, which can be as follows... Figure 8 The diagram shows a combined slide rail assembly comprising two first slide rail devices 100a extending longitudinally along the vehicle 200 and a second slide rail device 100b extending transversely along the vehicle 200. Furthermore, the interior trim assembly includes interior trim disposed on the second slide rail device 100b. Here, the interior trim may be a seat 201.

[0065] Here, the second slide rail device 100b is constructed as the slide rail device 100 according to the present disclosure, whereby the opening width W of the slide rail assembly of the second slide rail device 100b is smaller, thus allowing it to be conveniently arranged on the first slide rail device 100a. Of course, in other embodiments, depending on the actual application requirements, it is also conceivable that the first slide rail device 100a is the slide rail device 100 according to the present disclosure, while the second slide rail device 100b is a conventional slide rail device; or both the first slide rail device 100a and the second slide rail device 100b are the slide rail devices 100 according to the present disclosure.

[0066] It should be noted that the terminology used herein is for illustrative purposes only and is not intended to limit the disclosure. The singular forms “a” and “the one” as used herein should include the plural forms unless the context explicitly states otherwise. It is understood that the terms “comprising” and “including,” and other similar terms, when used in the application documents, specifically describe the presence of the stated operation, element, and / or component, without excluding the presence or addition of one or more other operations, elements, components, and / or combinations thereof.
