[0002] This application claims priority to Japanese Patent Application No. 2022-054935, filed on March 30, 2022, the entire contents of which, including the description, claims, drawings and abstract, are incorporated herein by reference. Technical Field

[0003] This specification discloses a vehicle compartment partition structure. Background Technology

[0004] A partition wall separating the interior and exterior of the vehicle is erected on the vehicle. Seats are also installed inside the vehicle. For example, in Japanese Patent Application Publication No. 2021-11232, seats are installed in the partition wall (side wall) of shared vehicles such as buses. More specifically, multiple longitudinal column members, also called pillars, are erected in the longitudinal direction of the vehicle as a skeletal component. A partition wall is installed between these pillars. Furthermore, the two ends of a seat crossbeam, which serves as a skeletal component supporting the seat, are fixed to a pair of adjacent pillars. A seat is mounted on this seat crossbeam.

[0005] However, in order to enhance the exterior design of vehicles, sometimes a partition separating the interior and exterior is constructed using window panels made of glass, resin, or other materials. In such cases, instead of using a long strip of window panel that covers the entire height of the partition, a layout in which multiple window panels are arranged vertically is sometimes adopted.

[0006] In the case of such a split window panel configuration, a window frame component is provided between the upper and lower window panels to support the edges of these window panels. For example, the two ends of this window frame component are fixed to an adjacent pair of pillars.

[0007] Here, although the supported objects (seat and window panel) are different, due to their commonalities in function (support function) and structure (fixed at both ends to a pair of adjacent pillars), a skeleton component integrating the seat crossbeam and window frame components can be considered. However, in this case, the skeleton component bears the load when the passenger sits on the seat, thus the skeleton component deflects, and consequently, the window panel supported by the skeleton component may deform.

[0008] On the other hand, when seat beams and window frame components are arranged separately, for example, along a partition wall in the vertical direction, decorative panels are sometimes required at the top and bottom as interior components covering these components, which increases costs compared to arranging them close together.

[0009] Therefore, this specification discloses a vehicle compartment partition structure that can centrally and effectively house window frame components and seat crossbeams, and can suppress the transmission of loads input to the seat crossbeams to the window frame components. Summary of the Invention

[0010] This specification discloses a vehicle compartment partition structure. The partition structure includes a window panel, a window frame component, a seat, and a seat crossbeam. The window panel is erected and forms part of the partition separating the interior and exterior of the vehicle. The window frame component supports the window panel. The seat is installed inside the vehicle, with its back facing the window panel. The seat crossbeam is a skeletal component supporting the seat. Furthermore, the window panel includes an upper window panel positioned above and a lower window panel positioned below the upper window panel. The window frame component, positioned between the upper and lower window panels, is a horizontal beam supporting the lower end of the upper window panel and the upper end of the lower window panel. Both ends of the window frame component along its length are fixed to a first support column, which serves as a longitudinal column of the vehicle compartment, and a second support column adjacent to the first support column. Both ends of the seat crossbeam along its length are also fixed to the first and second support columns. Furthermore, at least a portion of the window frame component and the seat crossbeam overlap in the vehicle height direction, and the window frame component and the seat crossbeam extend along their entire length with a horizontal gap smaller than the horizontal width of the window frame component and the seat crossbeam.

[0011] According to the above structure, the window frame component and the seat crossbeam are arranged side-by-side in the horizontal direction with a small gap smaller than their respective horizontal width, extending along their entire length. By separating them with such a small gap and arranging them side-by-side in the horizontal direction, both can be covered with a single decorative panel. In addition, by ensuring that the window frame component and the seat crossbeam do not contact each other along their entire length, the load transfer from the seat crossbeam to the window frame component is suppressed.

[0012] Furthermore, in the above structure, both ends of the window frame component can be directly fixed to the first and second pillars. Additionally, both ends of the seat crossbeam can be fixed to the first and second pillars via brackets.

[0013] Based on the above structure, the gap width between the window frame component and the seat crossbeam can be adjusted by means of the bracket.

[0014] Alternatively, in the above structure, the window frame component and the seat crossbeam may be arranged sequentially from the window panel toward the interior side of the vehicle. In this case, the window frame component has an outer window frame component disposed opposite to the exterior side of the vehicle and an inner window frame component disposed opposite to the interior side of the vehicle. The inner window frame component has a cap-shaped cross-section with a main body portion having a Π-shaped cross-section and an opening facing the exterior side of the vehicle, and a pair of flanges extending vertically from the opening end of the main body portion. The seat crossbeam is a square tube shape. The bracket has a receiving groove portion. The receiving groove portion has a Π-shaped cross-section and its opening faces the exterior side of the vehicle. Furthermore, the receiving groove portion receives the seat crossbeam and the main body portion of the inner window frame component from the interior side of the vehicle, and its opening end abuts against the flange of the inner window frame component. In this structure, the groove depth of the receiving groove portion exceeds the sum of the horizontal width of the seat crossbeam and the horizontal width of the main body portion of the inner window frame component.

[0015] According to the above structure, the amount exceeding the sum of the horizontal width of the seat crossbeam and the horizontal width of the main body of the inner window frame member in the groove depth of the receiving slot can be used as the gap width between the seat crossbeam and the inner window frame member. That is, the gap width between the seat crossbeam and the inner window frame member can be managed using the groove depth of the receiving slot of the bracket.

[0016] According to the cabin partition structure disclosed in this specification, the window frame components and seat crossbeams can be centrally and effectively arranged, and the transmission of loads input to the seat crossbeams to the window frame components can be suppressed.

[0026] The following description uses the accompanying drawings to illustrate the vehicle compartment partition structure according to the embodiments. The shapes, materials, quantities, and values ​​described below are illustrative examples and may be appropriately changed depending on the specifications of the vehicle compartment partition structure. Furthermore, the same symbols are used to denote equivalent elements in all the following drawings.

[0027] In addition, Figures 1-9 In this system, an orthogonal coordinate system consisting of the FR axis, RW axis, and UP axis is used to represent the position and orientation of each structure. The FR axis is the vehicle's front-to-rear direction axis with the front of the vehicle as the positive direction. The RW axis is the vehicle's width direction axis with the right side of the vehicle as the positive direction. The UP axis is the vehicle's vertical direction axis with the top as the positive direction.

[0028] Using this orthogonal coordinate system, the FR-RW plane becomes a horizontal plane. Furthermore, the horizontal plane is not limited to a plane perpendicular to the vertical axis, but also includes planes with angular differences (angular errors) relative to that vertical plane that are within the dimensional tolerances set in the vehicle assembly process.

[0029] As described below, as a vehicle-mounted device, the vehicle compartment partition structure involved in this embodiment includes an upper window panel 13 (see reference). Figure 2 The upper window panel 14 and the seat 50 are arranged opposite to these window panels on the back. Moreover, as a supporting structure for the vehicle equipment, the cabin partition structure includes window frame components 60 that support the upper window panel 13 and the lower window panel 14, and seat crossbeams 70 that support the seat 50.

[0030] As shown in the figure, the window frame component 60 and the seat crossbeam 70 are arranged with a gap W1 between them in the horizontal direction (vehicle width direction) along their entire length. This separation arrangement suppresses the transmission of loads input to the seat crossbeam 70 (such as torsional loads when the passenger is seated) to the window frame component 60. Details of the arrangement structure of the window frame component 60 and the seat crossbeam 70 will be described later.

[0031] <Vehicle Exterior>

[0032] Figure 1 The image shows the exterior of a vehicle 10 equipped with the cabin partition structure according to this embodiment. (See also...) Figure 1The orthogonal coordinate system shown depicts the right side and rear of vehicle 10 on the paper. Vehicle 10 is, for example, a carpool vehicle such as a bus. The boarding and alighting area of ​​vehicle 10 is, for example, located on the left side of the vehicle (not shown).

[0033] The vehicle 10 has multiple window panels erected as part of a partition separating the interior and exterior of the vehicle. These window panels are arranged, for example, along the vehicle's longitudinal and vertical directions. For example, upper window panels 11, 13, and 15, which are positioned at the top, are arranged in the longitudinal direction. In addition, lower window panels 12, 14, and 16, which are positioned below the upper window panels 11, 13, and 15, are arranged in the longitudinal direction.

[0034] Upper window panels 11, 13, 15 and lower window panels 12, 14, 16 are positioned between the pillars that serve as longitudinal columns of the vehicle compartment. For example, vehicle 10 has pillar A 21, pillar B 30 (first pillar), pillar C 40 (second pillar), and pillar D 22 from the front to the rear.

[0035] The upper window panel 11 and the lower window panel 12 are located between column A 21 and column B 30. The upper window panel 13 and the lower window panel 14 are located between column B 30 (the first column) and column C 40 (the second column). The upper window panel 15 and the lower window panel 16 are located between column C 40 and column D 22.

[0036] For example, the upper window panels 11, 13, and 15 and the lower window panels 12, 14, and 16 are made of glass or resin. For example, the upper window panels 11, 13, and 15 and the lower window panels 12, 14, and 16 can all be rectangular in shape.

[0037] <Supporting Structure of Window Panels>

[0038] The upper window panels 11, 13, and 15, and the lower window panels 12, 14, and 16 are each supported on their four sides by the vehicle body's frame structure. For example, the upper end of the upper window panel 13, located at the center of the vehicle's longitudinal direction, is supported by the vehicle's roof longitudinal beam (not shown), and its front and rear ends are supported by pillar B 30 (first pillar) and pillar C 40 (second pillar). Furthermore, as described later... Figure 8 As shown, the lower end of the upper window panel 13 is supported by the window frame component 60.

[0039] Additionally, the lower end of the lower window panel 14, located at the center of the vehicle's front-to-rear direction, is supported by the vehicle's door sill panel (not shown), and its front and rear ends are supported by pillar B 30 (first pillar) and pillar C 40 (second pillar). Furthermore, as described later... Figure 8 As shown, the upper end of the lower window panel 14 is supported by the window frame component 60.

[0040] Reference Figure 2The window frame component 60 is part of the rectangular frame supporting the upper and lower window panels 13 and 14, and is in the shape of a horizontal beam extending along the vehicle's longitudinal direction. Both ends of the window frame component 60 are fixed to B-post 30 (first post) and C-post 40 (second post) adjacent to B-post 30. The fixing structure to B-post 30 and C-post 40 will be described later.

[0041] Reference Figure 8 The window frame component 60 is disposed between the upper window panel 13 and the lower window panel 14, supporting the lower end of the upper window panel 13 and the upper end of the lower window panel 14. The window frame component 60 has a closed cross-section structure, for example, consisting of a pair of split bodies. That is, the window frame component 60 has an inner window frame component 61 disposed opposite to the interior side of the vehicle and an outer window frame component 65 disposed opposite to the exterior side of the vehicle.

[0042] Both the inner window frame component 61 and the outer window frame component 65 have a cap-shaped cross-section, forming a closed cross-section structure by connecting their openings.

[0043] That is, the inner window frame component 61 has a main body 62 with a cross-section Π shape and its opening facing the outside of the vehicle body, and a pair of flanges 63, 63 extending vertically from the opening end of the main body 62.

[0044] Similarly, the outer window frame component 65 has a main body 66 with a Π-shaped cross-section and its opening facing the interior of the vehicle, and a pair of flanges 67, 67 extending vertically from the opening end of the main body 66. The flanges 63, 67 are joined by welding or the like to form a closed cross-section structure.

[0045] The side portion 66A (the panel portion disposed on the outer side in the vehicle width direction) of the main body portion 66 of the outer window frame component 65 is opposite to the lower end of the upper window panel 13 and the upper end of the lower window panel 14. Adhesive layers 13A and 14A and sealing layers 13B and 14B are provided between the side portion 66A and the upper window panel 13 and between the side portion 66A and the lower window panel 14. The upper window panel 13 and the lower window panel 14 are joined (fixed) to the outer window frame component 65 by means of the adhesive layers 13A and 14A.

[0046] In addition, such as Figure 8 As illustrated, at least a portion of the window frame component 60 and the seat crossbeam 70 overlap in the vehicle height direction (vertical position). Figure 8 The image shows an example where the center positions of the window frame component 60 and the seat crossbeam 70 are aligned in the vehicle height direction.

[0047] In this way, by aligning the window frame component 60 and the seat crossbeam 70 in the vehicle height direction, storage capacity is improved compared to the case of misalignment, for example, the trim panel, as an interior component, can cover both as a single unit.

[0048] In addition, such as Figure 8 , Figure 9 As illustrated, the vehicle height dimensions of the main body 62 of the window frame component 60 and the seat crossbeam 70 can be equal. Furthermore, "equal" also includes cases where there is a dimensional difference within the dimensional tolerances imposed during manufacturing. By aligning the vehicle height positions of the window frame component 60 and the seat crossbeam 70 and ensuring that the vehicle height dimensions of the main body 62 of the window frame component 60 and the seat crossbeam 70 are equal, the main body 62 of the window frame component 60 and the seat crossbeam 70 can be reliably stored in the receiving slot 81 of the support bracket 80.

[0049] <Seats and Seat Support Structures>

[0050] Figure 2 The image shows 50 seats installed inside the vehicle interior. Furthermore, in... Figure 3 The image illustrates the support structure (frame) that supports the seat 50. For example, in the vehicle interior, a three-seat seat 50 is provided between the B pillar 30 (first pillar) and the C pillar 40 (second pillar).

[0051] The seat 50 includes a seat cushion 51 as the seat and a seat back 55 as the backrest. The back of the seat back 55 is positioned opposite to the upper window panel 13 and the lower window panel 14. The seat cushion 51 is fastened to the seat beam 72 and the seat crossbeam 75 via a seat cushion bracket 52. For example, the seat cushion 51 is a so-called flip-up type, which can rotate up and down about the seat cushion bracket 52 as a rotation axis.

[0052] Reference Figure 3 As the frame components supporting the seat 50, seat crossbeams 70 and 75, seat beams 72, and seat pillars 71 are provided in the vehicle compartment. Furthermore, an upper bracket 73, a lower bracket 74, and a seat cushion bracket 52 are installed on these frame components (see reference). Figure 2 ).

[0053] The seat crossbeams 70 and 75 are spaced apart along the vehicle's height (vertical direction). (Refer to...) Figure 8 The seat crossbeams 70 and 75 are, for example, square tubular in shape, with both ends fixed along their length. Figure 3 Example B-pillar 30 (first pillar) and C-pillar 40 (second pillar). In this fixing, the seat crossbeam 70, which is disposed above, is fixed to the B-pillar 30 (first pillar) and C-pillar 40 (second pillar) via pillar bracket 80. In addition, the seat crossbeam 75, which is disposed below, is fixed to the B-pillar 30 and C-pillar 40 via pillar bracket 110.

[0054] In addition, such as Figure 8 , Figure 9As illustrated, a window frame component 60 and a seat crossbeam 70 are sequentially arranged from the upper window panel 13 and the lower window panel 14 toward the interior of the vehicle. Furthermore, the window frame component 60 and the seat crossbeam 70 are spaced apart by a gap W1 in the horizontal direction (vehicle width direction). To achieve this separation, the window frame component 60 is directly fixed to the B-pillar 30 (first pillar) and the C-pillar 40 (second pillar), while the seat crossbeam 70 is fixed to the B-pillar 30 and the C-pillar 40 via a pillar bracket 80. Details of this fixing structure will be described later.

[0055] Reference Figure 3 Seat supports 71 and seat beams 72 are provided between seat crossbeams 70 and 75. Seat supports 71 are longitudinal column components, and the number of seat supports 71, equal to the number of seats in seat 50, is provided between seat crossbeams 70 and 75. For example, in... Figure 3 In this example, three seat pillars 71 are evenly spaced in the front-rear direction of the vehicle. For example, the upper end of the seat pillar 71 is welded to the seat crossbeam 70, and the lower end is welded to the seat crossbeam 75.

[0056] The seat beam 72 of the crossbeam component extends and is mounted on multiple seat supports 71. For example, the seat beam 72 does not abut against support B 30 and support C 40, and is configured such that its length dimension is shorter than the distance between the two supports.

[0057] An upper bracket 73 is installed on the seat crossbeam 70. The upper bracket 73 is installed on the seat crossbeam 70 across the upper end of the seat pillar 71. Additionally, a lower bracket 74 is installed on the seat beam 72. The lower bracket 74 is installed on the seat beam 72 across the seat pillar 71.

[0058] exist Figure 4 The back of the seat back 55 is illustrated. The seat back 55 is composed of two parts, for example, a back panel 56 and a support plate 57. The support plate 57 is provided in the upper part of the back panel 56. A hook-shaped engaging claw 57A and an aligning pin 57B are provided at the rear end of the support plate 57. In addition, a through hole 56A is provided in the lower part of the back panel 56, extending through the thickness direction of the back panel 56.

[0059] Reference Figures 2-4 The engaging claw 57A hook is attached to the upper bracket 73. At this time, the support plate 57 (refer to...) Figure 4 The aligning pin 57B is fitted into the cutout 73A of the upper bracket 73.

[0060] By engaging the aligning pin 57B with the notch 73A of the upper bracket 73, the through hole 56A of the seat back and the through hole 74A of the lower bracket 74 are axially aligned. The seat back 55 is then secured to the lower bracket 74 by bolts being screwed into these through holes.

[0061] Reference Figure 2 , Figure 3 The seat cushion 51 and the seat cushion bracket 52 are, for example, pre-assembled as a single unit. For example, seat cushion brackets 52 are installed on both sides of the seat cushion 51. The fastening holes (not shown) provided on the upper and lower parts of the seat cushion bracket 52 are aligned with the fastening holes 72A of the seat beam 72 and the fastening holes 75A of the seat crossbeam 75, and the seat cushion bracket 52 is fastened to the seat beam 72 and the seat crossbeam 75 by bolts and nuts.

[0062] In addition, armrests (not shown) are sometimes provided around the perimeter of the seat 50. In this case, the armrests are fixed to the seat crossbeam 70, and the window frame component 60 is not the installation destination. By preventing the window frame component 60 from contacting the armrests, the transmission of loads input from the armrests to the upper window panel 13 and the lower window panel 14 is suppressed.

[0063] <Connection structure of seat beams and window frame components to pillars>

[0064] exist Figures 5-8 The diagram illustrates the connection structure between the seat crossbeam 70 and the window frame component 60 to the B-pillar 30 (first pillar) in the vehicle compartment partition structure according to this embodiment. Furthermore, due to the symmetry of the vehicle structure, the connection structure between the seat crossbeam 70 and the window frame component 60 to the C-pillar 40 (second pillar) also possesses... Figures 5-9 Same structure.

[0065] Both ends of the window frame component 60 are directly fixed to the B-post 30 and the C-post 40. On the other hand, both ends of the seat crossbeam 70 are fixed to the B-post 30 and the C-post 40 via the post bracket 80. (See reference...) Figure 8 and Figure 9 Through this different fixing method, the window frame component 60 and the seat crossbeam 70 extend along their entire length, separated by a horizontal gap W1. As described later, the gap W1 is defined as being larger than the main body 62 of the window frame component 60 (see reference 62). Figure 8 The horizontal width W4 (vehicle width) of the seat crossbeam 70 and the horizontal width W3 (vehicle width) of the seat crossbeam 70 are both shorter.

[0066] exist Figure 6 In the example, from Figure 5 The structure is shown after removing the support bracket 80 and the seat crossbeam 70. Furthermore, the structure surrounding support B 30 will be described below; however, if the tens digit of the symbol is replaced with 4, the description will then become the description of the structure surrounding support C 40.

[0067] Reference Figure 2 , Figure 5The B-pillar 30 has a closed cross-section structure and includes an inner pillar member 31 disposed opposite to the inside of the vehicle interior and an outer pillar member 35 disposed opposite to the outside of the vehicle interior. The inner pillar member 31 has a main body 32 with a Π-shaped cross-section and its opening facing the outside of the vehicle interior, and a pair of flanges 33 and 34 extending from the opening end of the main body 32 in the vehicle longitudinal direction.

[0068] Similarly, the outer member of the pillar 35 has a main body 36 with a Π-shaped cross-section and an opening facing the interior of the vehicle, and a pair of flanges 37 and 38 extending from the opening end of the main body 36 in the longitudinal direction of the vehicle. In addition, the flange 38 of the outer member of the pillar 35 near the window frame member 60 is configured such that its extension width in the longitudinal direction of the vehicle is longer than that of the flange 34 of the inner member of the pillar 31 opposite to it.

[0069] In this way, by making the extension lengths different between flanges 34 and 38, the engagement method can be changed at the location where the window frame component 60 engages with both flanges 34 and 38 and at the location where the window frame component 60 engages with only flange 38.

[0070] For example, if flanges 34 and 38 are thick-walled, it becomes difficult to weld the four overlapping pieces of flanges 34 and 38, flange 63 of the inner window frame component 61, and flange 67 of the outer window frame component 65. Therefore, by performing a three-piece overlapping weld of flange 38, flange 63 of the inner window frame component 61, and flange 67 of the outer window frame component 65, the window frame component 60 can be joined to the B-pillar 30.

[0071] As described above, the window frame component 60 includes an inner window frame component 61 and an outer window frame component 65. (Refer to...) Figure 6 The outer window frame member 65 is configured such that its front-to-rear dimensions are longer than those of the inner window frame member 61. Therefore, the front and rear ends of the flange 67 of the outer window frame member 65 engage with both the flange 34 of the inner pillar member 31 and the flange 38 of the outer pillar member 35. Conversely, the flange 63 of the inner window frame member 61 terminates in front of the flange 34 of the inner pillar member 31. Consequently, the flange 63 of the inner window frame member 61 engages only with the flange 38 of the flange 34 of the inner pillar member 31 and the flange 38 of the outer pillar member 35.

[0072] A notch 64 is formed on the flange 63 of the inner window frame member 61. Corresponding to the area of ​​the notch, a seat surface 67A is provided protruding from the flange 67 of the outer window frame member 65. Alternatively, a seat surface 38A that coincides with the seat surface 67A may also be provided protruding from the flange 38 of the outer member 35 of the support column.

[0073] Reference Figure 5 , Figure 6These seat surfaces 67A, 38A and the second flange 83 of the support bracket 80 overlap and are welded together at three overlapping points 83B. Additionally, a welding point 83A is provided adjacent to the welding point 83B. The welding point 83A is formed by overlapping and welding together the flange 63 of the inner window frame member 61, the flange 67 of the outer window frame member 65, the flange 38 of the outer support member 35 and the second flange 83 of the support bracket 80, forming four overlapping pieces.

[0074] Furthermore, the front end of the flange 67 of the outer window frame component 65 coincides with the flange 38 of the outer member of the support column 35 and is provided with a welding point 67B. Moreover, the flange 67 coincides with the flange 38 of the outer member of the support column 35 and the flange 34 of the inner member of the support column 31 and is provided with a welding point 67C.

[0075] Reference Figure 5 The support bracket 80 is a fixing component used to fix the seat crossbeam 70 to the B support 30 (first support). The support bracket 80 has a receiving groove 81, a first flange 82 and a second flange 83.

[0076] The first flange 82 abuts against the cab surface 32A of the main body portion 32 of the support inner member 31 and is fastened thereto with bolts and nuts. Furthermore, if a welding electrode can be inserted into the hollow portion of the B support 30, the first flange 82 is welded to the main body portion 32 of the support inner member 31 instead of being fastened with bolts and nuts.

[0077] The second flange 83 is connected to the end of the first flange 82 and extends along the side 32B of the inner member 31 and the flange 38 of the outer member 35. As described above, the second flange 83 is provided with a welding point 83A that coincides with the flange 63 of the inner window frame member 61, the flange 67 of the outer window frame member 65, and the flange 38 of the outer member 35. In addition, the second flange 83 is provided with a welding point 83B that coincides with the flange 67 of the outer window frame member 65 and the flange 38 of the outer member 35.

[0078] Reference Figure 7 , Figure 8 The receiving groove 81 is a square groove with a cross-section in the shape of a Π, and its opening faces outward in the vehicle width direction. At the end of the opening, a pair of second flanges 83, 83 extend in the vertical direction.

[0079] The receiving groove 81 houses the square tube-shaped seat crossbeam 70 and the main body 62 of the inner window frame component 61. For example, the seat crossbeam 70 is inserted into the receiving groove 81 until it abuts against the bottom plate 81A of the receiving groove 81. In this inserted position, the seat crossbeam 70 and the receiving groove 81 are fixed to each other by means of arc welding or the like.

[0080] Furthermore, the main body 62 of the inner window frame component 61 is inserted into the receiving groove 81. The open end of the receiving groove 81 abuts against the flange 67 of the inner window frame component 61.

[0081] Here, as Figure 8 As illustrated, the depth W2 of the receiving groove 81 exceeds the sum of the vehicle width dimension W3 of the seat crossbeam 70 and the vehicle width dimension W4 of the main body 62 of the inner window frame member 61 (W2 > W3 + W4). As described above, the seat crossbeam 70 is inserted until it abuts against the bottom plate 81A of the receiving groove 81, and the main body 62 is inserted into the receiving groove 81 to the depth until the open end of the receiving groove 81 abuts against the flange 63. As a result, a gap W1 is created in the vehicle width direction (horizontal direction) between the seat crossbeam 70 and the main body 62 within the receiving groove 81. The gap W1 is equal to the value obtained by subtracting the sum of the vehicle width dimension W3 of the seat crossbeam 70 and the vehicle width dimension W4 of the main body 62 of the inner window frame member 61 from the depth W2 of the receiving groove 81 (W1 = W2 - (W3 + W4)).

[0082] In this way, the seat crossbeam 70 and the window frame component 60 are spaced apart in the vehicle width direction (horizontal direction) by the support bracket 80, thus... Figure 8 , Figure 9 As illustrated, the seat crossbeam 70 and the window frame component 60 are spaced apart along their entire length in the vehicle width direction (horizontal direction).

[0083] For example, the gap W1, which is the spacing width, can be greater than 1 mm and less than 10 mm. For example, the support bracket 80 is manufactured by stamping. It is known that stamping can set the machining accuracy to less than 0.1 mm. Therefore, the gap W1 can be managed with high precision in the manufacturing process of the support bracket 80.

[0084] Furthermore, in the above embodiments, an example of applying the vehicle compartment partition structure according to this embodiment to the side structure of the vehicle compartment is shown, but the vehicle compartment partition structure according to this embodiment is not limited to this method.

[0085] For example, a cabin partition structure may include window panels (upper and lower) located on a portion of the rear wall of the cabin, and a seat facing away from the window panel. Furthermore, a window frame component supporting the window panel and a seat crossbeam supporting the seat are included in the cabin partition structure. The two ends of the window frame component and the seat crossbeam are connected to a pair of pillars spaced apart in the vehicle width direction.

[0086] This disclosure is not limited to the above-described embodiments, but includes all changes and modifications without departing from the technical scope or essence of the invention as defined by the claims.
