Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above prior art, since it is necessary to provide recesses and protrusions on the console housing and the roof module sides, respectively, the shapes of the console housing and the roof module become complicated.

[0005] In consideration of the above facts, an object of the present invention is to obtain an attachment structure of a roof member that can suppress the fall of the roof member against the movement of the sun visor inward in the vehicle width direction due to a side collision of the vehicle with a simple configuration.

Means for Solving the Problems

[0006] The mounting structure for the roof member according to the first embodiment comprises a ceiling material provided on the interior ceiling of a vehicle and constituting the interior design of the vehicle interior; a roof member inserted into an opening formed in the ceiling material and attached to the interior ceiling; and a sun visor provided on the ceiling material and positioned outside the roof member in the vehicle width direction, and which can be deployed or retracted relative to the ceiling material, wherein the roof member has a locking portion formed thereon, which locks the end of the sun visor directly or indirectly via the ceiling material when the sun visor moves inward in the vehicle width direction due to a collision load input from the outside in the vehicle width direction toward the inside in the vehicle width direction.

[0007] The mounting structure for the roof member according to the first embodiment comprises a ceiling material, a roof component, and a sun visor. The ceiling material is provided on the interior ceiling of the vehicle and constitutes the interior design of the vehicle. An opening is formed in the ceiling material, into which the roof member is inserted and attached to the interior ceiling. Furthermore, the sun visor is provided on the ceiling material, positioned outside the roof member in the vehicle width direction, and is deployable or retractable relative to the ceiling material.

[0008] In this embodiment, the roof member is provided with a locking portion. This locking portion is configured to lock the end of the sun visor directly or indirectly via the ceiling material when the sun visor moves inward in the vehicle width direction due to a collision load (so-called side impact load) input from the outside in the vehicle width direction toward the inside in the vehicle width direction.

[0009] In other words, in this embodiment, the end of the sun visor, which moves inward in the vehicle width direction due to a side impact load, is locked into a locking part provided on the roof member, thereby preventing (suppressing) the roof member from falling. Thus, in this embodiment, since it is only necessary to provide a locking part on the roof member to which the sun visor is locked, it is possible to suppress the falling of the roof member with a simpler configuration compared to, for example, a comparative example in which the ceiling material and the roof member are locked to each other so that the roof member does not fall even if the sun visor collides with it.

[0010] The mounting structure for the roof member according to the second embodiment is the same as the mounting structure for the roof member according to the first embodiment, wherein the roof member is provided with a clip base to which a clip for attachment to the interior ceiling is attached, and the locking portion is provided including the side wall portion of the clip base and is configured to include a recess into which the end of the sun visor can enter when the sun visor moves inward in the vehicle width direction.

[0011] In the mounting structure for the roof member according to the second embodiment, the roof member is provided with a clip base to which a clip for attachment to the interior ceiling is attached. Therefore, the clip base is attached to the interior ceiling via the clip. In this way, the roof member is attached to the interior ceiling. The locking portion is configured to include a recess, and the recess is provided including the side wall portion of the clip base. The end of the sun visor can enter this recess when the sun visor moves inward in the vehicle width direction.

[0012] Therefore, when the sun visor moves inward in the vehicle width direction due to a so-called side impact load, the end of the sun visor enters the recess and is locked in place. In other words, in this embodiment, the roof member is locked to the end of the sun visor via the recess, and the roof member is prevented from falling.

[0013] The "recess" may be formed on the side wall of the clip base, or it may be configured such that the recess is formed between the clip base and the side wall.

[0014] The mounting structure for the roof member according to the third embodiment is the mounting structure for the roof member according to the second embodiment, wherein the roof member is provided with a clip base to which a clip for attachment to the interior ceiling is attached, and the locking portion is configured to include a locking piece that protrudes outward in the vehicle width direction from the side wall of the clip base and can lock the end of the sun visor when the sun visor moves inward in the vehicle width direction.

[0015] In the roof member mounting structure according to the third embodiment, the locking portion is configured to include a locking piece, which protrudes outward in the vehicle width direction from the side wall portion of the clip base, and the end of the sun visor can be locked to the locking piece when the sun visor moves inward in the vehicle width direction.

[0016] Thus, in this embodiment, the roof member is secured to the end of the sun visor via the locking piece, thereby preventing the roof member from falling.

[0017] The mounting structure for the roof member according to the fourth embodiment is such that, in the mounting structure for the roof member according to the first embodiment, a flange portion protrudes outward from the tip of the peripheral wall portion of the roof member, and the external dimensions of the flange portion are formed to be larger than the internal dimensions of the opening.

[0018] In the fourth embodiment of the roof member mounting structure, a flange portion protrudes outward from the tip of the peripheral wall portion of the roof member. By forming the outer dimensions of this flange portion to be larger than the inner dimensions of the opening formed in the ceiling material, the inner edge of the opening is not visible on the design side. In other words, in this embodiment, the gap between the roof member and the ceiling material is not exposed on the design side, improving the aesthetic appearance. [Effects of the Invention]

[0019] As described above, according to the attachment structure of the roof member according to the present invention, with a simple configuration, it is possible to suppress the fall of the roof member against the inward movement of the visor in the vehicle width direction due to a side collision of the vehicle, and it has an excellent effect.

[0021] A mounting structure for a roof member according to one embodiment of the present invention will be described with reference to the drawings. In these drawings, arrows FR indicate the front of the vehicle, arrows UP indicate the upper side of the vehicle, and arrows LH indicate the left side of the vehicle. Hereafter, when simply referring to the front / rear, up / down, and left / right directions, unless otherwise specified, these refer to the front / rear in the vehicle's front-rear direction, up / down in the vehicle's up-down direction, and left / right in the vehicle's left-right direction. In addition, some reference numerals may be omitted in each drawing for the sake of clarity.

[0022] <Configuration of the mounting structure for roof components> First, the configuration of the mounting structure for the roof member according to this embodiment will be described.

[0023] Figure 1 shows a perspective view from the right rear of a vehicle, showing the roof member 14 attached to the interior ceiling 12 located at the front and top of a vehicle 10 to which the mounting structure of the roof member 14 according to this embodiment is applied. The roof member 14 may be provided with various switches, such as a lighting component and its switch, a switch for the sunroof, and storage compartments such as an overhead console.

[0024] The interior ceiling 12 is provided with a ceiling material 18 that constitutes the design of the interior 16 (see Figure 5). An opening 18A is formed in the front part of the ceiling material 18 and in the center in the vehicle width direction, and a roof member 14 can be inserted into this opening 18A and attached to the interior ceiling 12. On both sides of the opening 18A in the vehicle width direction, there are bulging portions 18B that bulge outwards toward the upper side of the vehicle. A sun visor 20 (see Figure 5) can be stored in these bulging portions 18B.

[0025] Here, the interior ceiling section 12, as shown in Figures 9 and 10, is composed of a pair of roof side rails 22 that extend along the vehicle's longitudinal direction on both outer sides in the vehicle's width direction, and a plurality of cross members 24 that are provided at predetermined distances in the vehicle's longitudinal direction, spanning between the pair of roof side rails 22 along the vehicle's width direction. The member provided at the front end of the cross member 24 is called the front header 26, and a metal bracket 28 (see Figure 4) is attached to the front header 26. The roof member 14 is attached to the front header 26 via this bracket 28. Figures 9 and 10 show the state in which the pole P has collided, as will be described later.

[0026] As shown in Figures 4 and 5, when the bracket 28 is cut along the vehicle width direction, its cross-sectional shape is roughly hat-shaped with an opening on the lower side of the vehicle. Briefly, the bracket 28 is composed of a pair of vertical wall portions 28A facing each other in the vehicle width direction, a connecting wall 28B connecting the upper ends of the vertical wall portions 28A, and flange portions 28C extending in a direction away from each other (outward in the vehicle width direction) from the lower ends of the vertical wall portions 28A. The bracket 28 is sized so that the vertical wall portions 28A and the connecting wall 28B substantially cover the roof member 14 from the outside.

[0027] As shown in Figure 1, in this embodiment, the opening 18A formed in the ceiling material 18 is substantially rectangular in shape, and the roof member 14 is substantially box-shaped to match the shape of the opening 18A. The roof member 14 is made of resin, and the peripheral wall portion 30 is formed to a size that can be inserted into the opening 18A.

[0028] Furthermore, as shown in Figure 2, multiple ribs 32 are formed on the outer surface 30A side of the peripheral wall portion 30 along the height direction of the peripheral wall portion 30. The formation of these ribs 32 reinforces the peripheral wall portion 30 and suppresses deformation of the peripheral wall portion 30. Figure 2 is a top view of the roof member 14.

[0029] Furthermore, as shown in Figure 1, a clamping portion 36 is erected in the center of the upper wall portion 34 of the roof member 14, facing upward toward the vehicle. The clamping portion 36 is composed of a pair of clamping pieces 36A, and a wire harness 38 for supplying power to electronic components attached to the roof member 14 or transmitting electrical signals can be clamped through this pair of clamping pieces 36A.

[0030] Furthermore, rectangular tubular clip bases 40 are erected at the corners of the upper wall portion 34 of the roof member 14, facing upward toward the vehicle. These clip bases 40 are formed either substantially flush with the outer surface 30A of the peripheral wall portion 30 of the roof member 14 or slightly inward from the outer surface 30A. Clips 42 are attached to the upper wall portion 40A that constitutes the upper end of these clip bases 40, and these clips 42 are attached to the connecting wall 28B of the bracket 28, as shown in Figure 5.

[0031] Then, as shown in Figure 6, the roof member 14 is attached to the bracket 28 with these clips 42 attached to the connecting wall 28B of the bracket 28. The flange portion 28C of the bracket 28 is positioned opposite the peripheral portion 18C of the opening 18A formed in the ceiling material 18.

[0032] On the other hand, a flange portion 44 protrudes from the tip of the peripheral wall portion 30 of the roof member 14 toward the outside of the roof member 14. This flange portion 44 protrudes outward beyond the inner edge of the opening 18A formed in the ceiling material 18, and covers the inner edge of the opening 18A from the lower side of the vehicle when the roof member 14 is attached to the bracket 28.

[0033] Therefore, the peripheral portion 18C of the opening 18A is formed to be lower to the vehicle than the opening 18A, and an inclined portion 18D is formed in the peripheral portion 18C of the opening 18A that slopes upward toward the vehicle toward the inner edge of the opening 18A. Consequently, the flange portion 44 of the roof member 14 is positioned on the lower side of the vehicle toward the inclined portion 18D, and the flange portion 44 and the peripheral portion 18C of the opening 18A are substantially flush.

[0034] Now, let's explain the clip base 40.

[0035] As shown in Figures 1 and 2, the clip base 40 has a different shape depending on its position on the roof member 14, and is broadly classified into front clip bases 46 and 48 provided on the front side of the roof member 14, and rear clip bases 50 and 52 provided on the rear side of the roof member 14.

[0036] The front clip bases 46 and 48 are each provided with rectangular tubular side wall portions 46A and 48A, respectively. On the surfaces of the side wall portion 46A of the front clip base 46 and the side wall portion 48A of the front clip base 48 that face each other, triangular ribs 54 and 56 are formed along the height direction of the side wall portions 46A and 48A, respectively, reinforcing the front clip bases 46 and 48.

[0037] Furthermore, the rear clip base 50 has a rectangular cylindrical side wall portion 56 that is composed of two stages, including an upper stage portion 56A and a lower stage portion 56B, with the upper stage portion 56A having a smaller external dimension than the lower stage portion 56B.

[0038] On the other hand, the rear clip base 52 has a side wall portion 52A formed in a rectangular tube shape, with a projection (locking piece) 58 protruding from the upper side of the outer surface 52A1 located on the outside in the vehicle width direction. The projection 58 is provided with a pair of claw portions 60 that extend outward in the vehicle width direction from both ends of the side wall portion 52A in the vehicle front-rear direction, and the tips of the pair of claw portions 60 are connected by a rectangular connecting portion (locking piece) 62. This reinforces the claw portions 60.

[0039] Furthermore, the outer surface 52A1 of the side wall portion 52A is positioned inward from the peripheral wall portion 30 of the roof member 14, and a step portion 64 is provided between the side wall portion 52A and the peripheral wall portion 30. This step portion 64 forms a recess 66 between it and the protruding portion 58. This recess 66 is sized to allow the end portion 20A of the sun visor 20 to enter. The rear clip base 50 also has a protruding portion 58 and a recess 66 formed therein, similar to the rear clip base 52.

[0040] <Function and effect of the mounting structure for roof components> Next, the operation and effects of the roof member mounting structure according to this embodiment will be described.

[0041] In this embodiment, as shown in Figures 1 and 5, the mounting structure for the roof member 14 includes a ceiling material 18, the roof member 14, and a sun visor 20. The ceiling material 18 is provided in the interior ceiling portion 12 of the vehicle 10 and constitutes the design of the interior 16 of the vehicle.

[0042] Furthermore, an opening 18A is formed in the ceiling material 18, and the roof member 14 is inserted into this opening 18A. Here, the clip base 40 is formed either substantially flush with the outer surface 30A of the peripheral wall portion 30 of the roof member 14 or slightly inward from the outer surface 30A. Therefore, when inserting the roof member 14 into the opening 18A, the clip base 40 guides the roof member 14 toward the interior ceiling portion 12.

[0043] A clip 42 provided on the roof member 14 is attached to a mounting hole 28B1 formed in the connecting wall 28B of a bracket 28 provided on the interior ceiling portion 12 side, thereby attaching the roof member 14 to the interior ceiling portion 12 side. In this state, the flange portion 28C of the bracket 28 is positioned on the vehicle-upward side of the peripheral portion 18C of the opening 18A formed in the ceiling material 18, and the flange portion 44 of the roof member 14 is substantially flush with the peripheral portion 18C of the opening 18A.

[0044] In this embodiment, the outer dimensions of the flange portion 44 of the roof member 14 are formed to be larger than the inner dimensions of the opening 18A formed in the ceiling material 18. Therefore, the inner edge of the opening 18A is not visible from the passenger compartment 16 side. In other words, in this embodiment, the gap between the roof member 14 and the ceiling material 18 is not exposed on the passenger compartment 16 side, improving the aesthetic appearance.

[0045] Furthermore, since the flange portion 44 of the roof member 14 is substantially flush with the peripheral portion 18C of the opening 18A, a step difference in the vehicle's vertical direction between the flange portion 44 of the roof member 14 and the peripheral portion 18C of the opening 18A on the vehicle interior 16 side is suppressed, and in this embodiment, the aesthetic appearance is further improved.

[0046] Incidentally, as shown in Figures 9 and 10, when a pole P collides with the side of the vehicle 10 in a so-called pole collision, the collision load is applied from the outside in the vehicle width direction toward the inside in the vehicle width direction. As a result, the sun visor 20 moves toward the inside in the vehicle width direction.

[0047] In this embodiment, as shown in Figure 6, a locking portion 68 is provided on the rear clip base 52 provided on the roof member 14. The locking portion 68 is set to lock the end portion 20A of the sun visor 20, which moves inward in the vehicle width direction due to a side impact load.

[0048] The locking portion 68 includes a projection 58 that protrudes from the outer surface 52A1 of the side wall portion 52A of the rear clip base 52. Furthermore, the outer surface 52A1 of the side wall portion 52A is positioned inward from the peripheral wall portion 30 of the roof member 14, and a step portion 64 provided between the side wall portion 52A and the peripheral wall portion 30 forms a recess 66 between it and the projection 58. This recess 66 is sized to allow the end portion 20A of the sun visor 20 to enter.

[0049] As shown in Figure 7, when the sun visor 20 moves inward in the vehicle width direction due to the pole collision, the sun visor 20 presses and deforms the ceiling material 18 and bracket 28 inward in the vehicle width direction. With the vertical wall portion 28A of the bracket 28 in contact with the rear clip base 52 of the roof member 14, the vertical wall portion 28A inclins upward towards the vehicle as it moves outward in the vehicle width direction. As a result, guided by this vertical wall portion 28A, the end portion 20A of the sun visor 20 is guided upward in the vehicle vertical direction while moving inward in the vehicle width direction.

[0050] As a result, as shown in Figure 8, the end portion 20A of the sun visor 20 is restricted from moving upward in the vertical direction of the vehicle by the protrusion 58 of the rear clip base 52 of the roof member 14, and is housed within the recess 66 of the roof member 14, including at least the bracket 28. In other words, the end portion 20A of the sun visor 20 is locked to the roof member 14. This prevents the roof member 14 from falling in this embodiment.

[0051] In other words, in this embodiment, the end portion 20A of the sun visor 20, which moves inward in the vehicle width direction due to a lateral impact load, is locked into a locking portion 68 provided on the roof member 14, thereby preventing the roof member 14 from falling due to a collision with the sun visor 20.

[0052] Thus, in this embodiment, it is only necessary to provide a locking portion 68 on the roof member 14 to which the sun visor 20 is locked. Compared to a comparative example, for example (not shown), where the ceiling material 18 and the roof member 14 are locked to each other so that the roof member 14 does not fall even if the sun visor 20 collides with it, it is possible to suppress the falling of the roof member 14 with a simpler configuration.

[0053] (Supplementary explanation of the embodiment)

[0054] In the above embodiment, as shown in Figures 2 and 6, the locking portion 68 is composed of a protruding portion 58 formed by a pair of claw portions 60 and a connecting portion 62 on the outer surface 52A1 of the rear clip base 52 of the roof member 14, and a recess 66 formed between the outer surface 52A1 of the rear clip base 52 and the peripheral wall portion 30 of the roof member 14, but is not limited to this.

[0055] For example, the locking portion 68 may be a protruding portion 58 or a recessed portion 66. Furthermore, the protruding portion 58 is not limited to this shape, as it only needs to be able to lock onto the end portion 20A of the sun visor 20. Also, although the recessed portion 66 is formed between the outer surface 52A1 of the rear clip base 52 and the peripheral wall portion 30 of the roof member 14, it is sufficient that the recess is large enough for the end portion 20A of the sun visor 20 to enter, so the recess may also be formed on the outer surface 52A1 of the rear clip base 52.

[0056] Furthermore, in this embodiment, it was explained that when the sun visor 20 moves inward in the vehicle width direction, the end portion 20A of the sun visor 20 is guided upward in the vehicle vertical direction by the vertical wall portion 28A of the bracket 28. However, the vertical wall portion 28A of the bracket 28 is not necessarily required. In other words, even without the vertical wall portion 28A of the bracket 28, the effect of this embodiment can be obtained because, as a behavior of the sun visor 20, when the sun visor 20 moves inward in the vehicle width direction, the end portion 20A of the sun visor 20 moves upward in the vehicle vertical direction.

[0057] Although an example of the present invention has been described above, the present invention is not limited to the above, and it is of course possible to implement it in various ways without departing from its spirit. [Explanation of Symbols]
