[0019] Below, according to Figures 1 to 10 An embodiment in which a vehicle sun visor is embodied will be described.

[0020] <General Structure of Vehicle Sun Visor>

[0021] like Figure 1 As shown, the vehicle sun visor 10 includes a sun visor body 11, a vehicle body side fixing portion 20, and a support shaft 30. The vehicle sun visor 10 is mounted on the front part of the roof of the vehicle, for example. The vehicle sun visor 10 is used to prevent light from outside the vehicle from directly hitting the eyes of passengers in the vehicle.

[0022] <Sun Visor Body>

[0023] The sun visor body 11 is made of resin. The sun visor body 11 has a first half-split body 12 and a second half-split body 13. The first half-split body 12 and the second half-split body 13 are shell-shaped. The sun visor body 11 is formed by assembling the first half-split body 12 and the second half-split body 13. The first half-split body 12 and the second half-split body 13 are joined to overlap each other. The sun visor body 11 is hollow. The sun visor body 11 is in the shape of a flat plate. When viewed from above, the sun visor body 11 is in a rectangular shape. The sun visor body 11 is arranged on the vehicle in such a way that the long side direction of the sun visor body 11 is consistent with the vehicle width direction.

[0024] The sun visor body 11 has a notch 16. The notch 16 is formed in an edge 11a extending along the long side direction of the sun visor body 11. In addition, the vehicle sun visor 10 has a cylindrical support shaft 17. The support shaft 17 is provided on the sun visor body 11 in a manner that crosses the notch 16 along the long side direction of the sun visor body 11. The support shaft 17 can be locked with a hook (not shown) provided on the ceiling of the vehicle.

[0025] A bearing portion 18 is provided inside the sun visor body 11. The bearing portion 18 is located near the edge portion 11a inside the sun visor body 11. The bearing portion 18 is arranged at a position overlapping with the notch 16 in the long side direction of the sun visor body 11. The bearing portion 18 is configured to rotatably support the support shaft 30 inserted into the inside of the sun visor body 11. The support shaft 30 is inserted into the inside of the sun visor body 11 from the side edge 11b located at one end in the long side direction of the sun visor body 11. In addition, since such a bearing portion 18 is already known, the detailed description of its structure is omitted.

[0026] <Body side fixing part>

[0027] The vehicle body side fixing part 20 is provided on the ceiling of the vehicle. The vehicle body side fixing part 20 is made of resin. The vehicle body side fixing part 20 is a bracket made of resin. Thus, since the vehicle body side fixing part 20 is made of resin, the aesthetics of the vehicle body side fixing part 20 when viewed from the vehicle interior becomes good. The vehicle body side fixing part 20 has a vehicle interior side surface 20a located on the vehicle interior side. In other words, the vehicle body side fixing part 20 has a vehicle interior side surface 20a exposed to the vehicle interior.

[0028] like Figure 2 As shown, an insertion hole 21 is formed in the vehicle body side fixing portion 20. The support shaft 30 is inserted into the insertion hole 21. The insertion hole 21 is open at the vehicle compartment side surface 20a of the vehicle body side fixing portion 20 and the back surface of the vehicle body side fixing portion 20 opposite to the vehicle compartment side surface 20a. The insertion hole 21 has a first opening portion opened at the vehicle compartment side surface 20a and a second opening portion opened at the back surface. The vehicle compartment side surface 20a is, for example, a curved surface convex toward the vehicle compartment.

[0029] The vehicle body side fixing portion 20 has a plurality of locking claws 22. Each locking claw 22 is provided in the second opening portion of the vehicle body side fixing portion 20. Each locking claw 22 protrudes from the second opening portion toward the axis of the insertion hole 21. Each locking claw 22 can be elastically deformed in a direction approaching or separating from the axis of the insertion hole 21. The locking claw 22 is provided in the second opening portion, for example, by forming a cut groove in the second opening portion. The cut groove is, for example, four cut grooves that divide the inner peripheral edge of the second opening portion into four.

[0030] <Support axis>

[0031] like Figure 1As shown, the support shaft 30 is in the shape of a long cylinder. The support shaft 30 supports the sun visor body 11 on the vehicle body side fixing portion 20. The support shaft 30 is bent into a substantially L-shape. The first end of the support shaft 30 is supported by the vehicle body side fixing portion 20. The second end of the support shaft 30 is supported by the bearing portion 18. In addition, a lighting device (not shown) is provided on the sun visor body 11. And wiring for supplying power to the lighting device is arranged inside the support shaft 30.

[0032] <Usage location and storage location>

[0033] The sun visor body 11 can rotate relative to the vehicle body side fixing portion 20 with the support shaft 30 as the rotation center. When the support shaft 17 is locked with the hook, the sun visor body 11 can rotate relative to the vehicle body side fixing portion 20 with the portion of the support shaft 30 supported by the bearing portion 18 as the rotation center. The sun visor body 11 can rotate between the use position and the storage position relative to the vehicle body side fixing portion 20. When the sun visor body 11 is in the use position, it is arranged opposite to the windshield. And when the sun visor body 11 is in the use position, the sun visor body 11 prevents light from outside the vehicle from directly hitting the eyes of the passengers in the vehicle. When the sun visor body 11 is in the use position, the first half-split body 12 is located on the passenger side, and the second half-split body 13 is located on the windshield side of the vehicle. When the sun visor body 11 is in the storage position, it is arranged along the ceiling of the vehicle. When the sun visor body 11 is located at the storage position, the first half-divided body 12 is located on the ceiling side of the vehicle, and the second half-divided body 13 is located on the side opposite to the ceiling.

[0034] <Detailed structure of the support shaft>

[0035] like Figure 3 and Figure 4 As shown, the support shaft 30 has a cylindrical core 31 and a coating resin 41. Figure 3 In the figure, the coating resin 41 is indicated by a double-dotted line. The barrel core 31 is made of metal. The coating resin 41 covers the outer peripheral surface of the barrel core 31. The coating resin 41 is formed by insert molding the barrel core 31 as an insert. Thus, the coating resin 41 is integrated with the barrel core 31. In this way, by covering the outer peripheral surface of the barrel core 31 with the coating resin 41, the aesthetics of the support shaft 30 when viewed from the interior of the vehicle becomes good.

[0036] <Core>

[0037] like Figure 3As shown, the cylinder core 31 is bent into a substantially L-shape. The cylinder core 31 is hollow. The cylinder core 31 is formed by bending a cylindrical metal cylinder. The cylinder core 31 has a first extension portion 32, a second extension portion 33, and a bent portion 34. The first extension portion 32 is a portion extending from the bent portion 34 and inserted into the insertion hole 21 of the vehicle body side fixing portion 20. The second extension portion 33 is a portion extending from the bent portion 34 in a direction substantially orthogonal to the first extension portion 32 and supported by the bearing portion 18. The bent portion 34 connects the first extension portion 32 and the second extension portion 33 to each other.

[0038] <Edge>

[0039] like Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, the core 31 has recesses 35. The recesses 35 are formed on the outer peripheral surface of the first extension portion 32. Two recesses 35 are provided on the outer peripheral surface of the first extension portion 32 at portions spaced 180 degrees apart in the circumferential direction of the first extension portion 32.

[0040] like Figure 5 As shown in FIG. 1 , each recess 35 is rectangular in plan view. Each recess 35 is formed on the outer peripheral surface of the first extension portion 32 in such a manner that the longitudinal direction of the recess 35 coincides with the axial direction of the first extension portion 32. Each recess 35 has an edge 36 on both sides in the longitudinal direction. In addition, the edge 36 is sometimes referred to as the end of the recess 35. The recess 35 and the edge 36 are formed by crushing a part of the first extension portion 32.

[0041] Each edge 36 extends in a direction perpendicular to the axis of the first extension portion 32. When the recessed portion 35 is viewed from above, the edge 36 at one end of the recessed portion 35 in the longitudinal direction is located on a straight line extending in a direction perpendicular to the axis of the first extension portion 32. When the recessed portion 35 is viewed from above, the edge 36 at the other end of the recessed portion 35 in the longitudinal direction is located on a straight line extending in a direction perpendicular to the axis of the first extension portion 32. In this way, each edge 36 extends in a direction intersecting the axial direction of the first extension portion 32 of the cylindrical core 31.

[0042] <Locking section>

[0043] like Figure 3 and Fig. 9 As shown, the core 31 has a stopper 37. The stopper 37 is provided at the top end of the first extension 32 on the opposite side to the bent portion 34. The stopper 37 is in a trumpet shape that increases in diameter toward the top end of the first extension 32. The stopper 37 is formed by performing trumpet groove processing on the top end of the first extension 32. In this way, the stopper 37 is provided at a portion of the core 31 that is located on the opposite side of the sun visor body 11 relative to the edge 36.

[0044] <Coating resin>

[0045] like Figure 3 and Figure 4 As shown, the coating resin 41 has a first resin portion 42, a second resin portion 43 and a third resin portion 44. The first resin portion 42 covers the outer peripheral surface of the first extension portion 32 of the barrel core 31. The second resin portion 43 covers the outer peripheral surface of the second extension portion 33 of the barrel core 31. The third resin portion 44 covers the outer peripheral surface of the bending portion 34 of the barrel core 31. The first resin portion 42 is cylindrical and extends along the outer peripheral surface of the first extension portion 32. The second resin portion 43 is cylindrical and extends along the outer peripheral surface of the second extension portion 33. The third resin portion 44 is cylindrical and bent along the outer peripheral surface of the bending portion 34. The third resin portion 44 connects the first resin portion 42 and the second resin portion 43 in the coating resin 41 to each other.

[0046] like Figure 4 As shown, the first resin portion 42 includes a large diameter portion 45, a small diameter portion 46, and a locking head portion 47. The large diameter portion 45 is continuous with the third resin portion 44. The small diameter portion 46 is continuous with the end portion of the large diameter portion 45 on the opposite side to the third resin portion 44. The outer diameter of the small diameter portion 46 is smaller than the outer diameter of the large diameter portion 45. The locking head portion 47 is continuous with the end portion of the small diameter portion 46 on the opposite side to the large diameter portion 45. The outer diameter of the locking head portion 47 is larger than the outer diameter of the small diameter portion 46 and smaller than the outer diameter of the large diameter portion 45.

[0047] like Fig. 9 As shown, the first end of the locking head 47 on the opposite side to the small diameter portion 46 covers the top end of the locking portion 37 of the barrel core 31. An opening hole 47h is formed at the first end of the locking head 47. The opening hole 47h is connected to the inside of the first extension portion 32 of the barrel core 31. The axis of the opening hole 47h is consistent with the axis of the first extension portion 32.

[0048] The first resin portion 42 is provided with a locked portion 48 to which the locking portion 37 of the barrel core 31 is locked. The locked portion 48 is formed on the inner surface of the locking head portion 47. The locked portion 48 is an annular recessed portion to which the locking portion 37 is locked. Furthermore, the locking portion 37 is locked to the locked portion 48, thereby preventing the first extension portion 32 from moving in the axial direction relative to the first resin portion 42. Therefore, the locking portion 37 is locked to the coating resin 41, thereby preventing the barrel core 31 from moving in the axial direction relative to the coating resin 41.

[0049] <Slit>

[0050] like Figure 4 , Figure 6 and Figure 7As shown in the figure, a slit 49 is formed in the coating resin 41. The slit 49 is formed in the large diameter portion 45 of the first resin portion 42. A slit 49 is formed in each portion of the large diameter portion 45 180 degrees apart along the circumferential direction. Each slit 49 is in the shape of an elongated hole. The long side direction of each slit 49 is orthogonal to the axial direction of the first resin portion 42.

[0051] The slit 49 exposes the edge 36 of the recess 35 which is farther from the bent portion 34. Therefore, the edge 36 of the recess 35 which is closer to the bent portion 34 is not exposed to the outside and is covered by the covering resin 41.

[0052] <Vulnerable Department>

[0053] When external force acts on the support shaft 30 and stress is applied to the barrel core 31, the barrel core 31 is easily damaged starting from the edge 36 exposed to the outside through the slit 49. Therefore, of the two edges 36 of the recessed portion 35, the edge 36 exposed to the outside through the slit 49 is the fragile portion 50. Therefore, the barrel core 31 has a fragile portion 50 that is configured to easily damage the barrel core 31. In this way, the fragile portion 50 of the present embodiment is an edge 36 formed by crushing a part of the barrel core 31. The slit 49 exposes the fragile portion 50 to the outside.

[0054] <Positional Relationship between Weak Portion and Slit and Side Surface of Cabin>

[0055] like Figure 2 As shown, the support shaft 30 is inserted into the insertion hole 21 until the locking head 47 passes over each locking claw 22 and protrudes from the second opening of the insertion hole 21. When the locking head 47 passes, each locking claw 22 is elastically deformed in a direction away from the axis of the insertion hole 21. And, when the locking head 47 passes over the corresponding locking claw 22, each locking claw 22 returns to its original shape. As a result, the step surface 42e between the small diameter portion 46 in the first resin portion 42 and the locking head 47 is locked to each locking claw 22. In this way, the first end of the support shaft 30 is supported by the vehicle body side fixing portion 20.

[0056] In a state where the support shaft 30 is supported by the vehicle body side fixing portion 20, the fragile portion 50 and the slit 49 are located on an imaginary plane 51 obtained by extending the vehicle cabin side surface 20a. The imaginary plane 51 passes through the vehicle cabin side surface 20a and crosses the first opening of the insertion hole 21. Therefore, the support shaft 30 is inserted into the insertion hole 21 in a manner that the fragile portion 50 and the slit 49 are located on the imaginary plane 51 obtained by extending the vehicle cabin side surface 20a.

[0057] [Effects of implementation methods]

[0058] Next, the operation of this embodiment will be described.

[0059] However, when an external force acts on the sun visor body 11, the external force acting on the sun visor body 11 sometimes acts on the support shaft 30. In the present embodiment, the fragile portion 50 is exposed to the outside through the slit 49. Therefore, when an external force acts on the support shaft 30 and stress is applied to the fragile portion 50, for example, compared with the case where the fragile portion 50 is covered with the covering resin 41, the barrel core 31 is easily broken starting from the fragile portion 50. In addition, the covering resin 41 is also easily broken starting from the slit 49. Therefore, due to the external force acting on the support shaft 30, while the barrel core 31 is broken starting from the fragile portion 50, the covering resin 41 is also easily broken starting from the slit 49. In this way, the barrel core 31 and the covering resin 41 are broken at the same time. Therefore, the fragile portion 50 becomes the starting point of the breaking of the barrel core 31.

[0060] like Fig.10 As shown in the figure, the broken parts of the core 31 and the coating resin 41 are located on the imaginary plane 51 obtained by extending the vehicle cabin side surface 20a of the vehicle body side fixing part 20. Therefore, it is possible to suppress the broken parts of the core 31 and the coating resin 41 from protruding from the vehicle cabin side surface 20a of the vehicle body side fixing part 20. In addition, when the core 31 breaks with the fragile part 50 as the starting point, the locking part 37 can prevent the core 31 from moving in the axial direction relative to the coating resin 41.

[0061] [Effects of Embodiment]

[0062] The following effects can be obtained in the above-mentioned embodiment.

[0063] (1) The fragile portion 50 is exposed to the outside through the slit 49. Therefore, for example, when an external force acts on the support shaft 30 and stress is applied to the fragile portion 50, the core 31 is more likely to be broken from the fragile portion 50 as a starting point, compared with the case where the fragile portion 50 is covered with the covering resin 41. Moreover, when the core 31 is broken from the fragile portion 50 as a starting point, the covering resin 41 is also more likely to be broken from the slit 49 as a starting point. Therefore, by breaking the core 31 and the covering resin 41 at the same time, even if an external force acts on the sun visor body 11, it is possible to suppress the external force acting on the sun visor body 11 from being applied to the vehicle body side fixing portion 20 through the support shaft 30.

[0064] (2) The support shaft 30 is inserted into the insertion hole 21 in such a manner that the fragile portion 50 and the slit 49 are located on the imaginary surface 51 obtained by extending the vehicle cabin side surface 20a. As a result, the damaged portion of the core 31 and the coating resin 41 can be located on the imaginary surface 51 obtained by extending the vehicle cabin side surface 20a of the vehicle body side fixing portion 20. As a result, the damaged portion of the core 31 and the coating resin 41 is unlikely to protrude from the vehicle cabin side surface 20a of the vehicle body side fixing portion 20 into the vehicle cabin. Therefore, it is possible to suppress the damaged portions of the core 31 and the coating resin 41 from protruding from the vehicle cabin side surface 20a of the vehicle body side fixing portion 20.

[0065] (3) By crushing a portion of the core 31, the edge 36 formed so as to extend in a direction intersecting the axial direction of the core 31 is used as the fragile portion 50. Therefore, the fragile portion 50 can be formed in the core 31 simply by crushing a portion of the core 31, and the structure of the core 31 can be simplified.

[0066] (4) A stopper 37 is provided at a portion of the core 31 that is located on the opposite side of the sun visor body 11 relative to the fragile portion 50. The stopper 37 is stopped by the coating resin 41 to prevent the core 31 from moving in the axial direction relative to the coating resin 41. Thus, for example, when the core 31 breaks with the fragile portion 50 as a starting point, the stopper 37 can prevent the core 31 from moving in the axial direction relative to the coating resin 41. As a result, for example, when the core 31 breaks with the fragile portion 50 as a starting point, it can be prevented that the broken portion of the core 31 protrudes more extremely into the vehicle interior than the damaged portion of the coating resin 41.

[0067] (5) Even if an external force acts on the sun visor body 11, it is possible to suppress the external force acting on the sun visor body 11 from being applied to the vehicle body side fixing portion 20 via the support shaft 30. As a result, for example, it is possible to suppress the vehicle body side fixing portion 20 from being broken, and it is easy to avoid the problem that the broken portion of the vehicle body side fixing portion 20 is exposed in the vehicle interior or the broken portion of the vehicle body side fixing portion 20 is scattered in the vehicle interior.

[0068] (6) Due to the external force acting on the support shaft 30, the core 31 is broken starting from the fragile portion 50, and the covering resin 41 is also broken starting from the slit 49. Therefore, the sun visor body 11 can be separated from the vehicle body side fixing portion 20. Therefore, even if the external force acts on the sun visor body 11, the external force acting on the sun visor body 11 can be prevented from being applied to the vehicle body side fixing portion 20 via the support shaft 30.

[0069] [Modifications]

[0070] In addition, the above-mentioned embodiment can be implemented as the following modifications. The above-mentioned embodiment and the following modifications can be implemented in combination with each other within the range that there is no technical contradiction.

[0071] ·like Fig.11 and Fig.12 As shown, the support shaft 30 may be arranged at a position where the fragile portion 50 and the slit 49 are located deeper into the insertion hole 21 relative to the vehicle compartment side surface 20a. Fig.11 As shown in FIG. 4 , the fragile portion 50 and the slit 49 are arranged at a position deeper into the insertion hole 21 than the imaginary surface 51. Fig.12As shown in the figure, the damaged portion of the core 31 and the coating resin 41 can be located at a position that is deeper into the inner side of the insertion hole 21 relative to the vehicle compartment side surface 20a of the vehicle body side fixing portion 20. As a result, the damaged portion of the core 31 and the coating resin 41 does not protrude from the vehicle compartment side surface 20a of the vehicle body side fixing portion 20 into the vehicle compartment. Therefore, it is possible to appropriately suppress the damaged portions of the core 31 and the coating resin 41 from protruding from the vehicle compartment side surface 20a of the vehicle body side fixing portion 20.

[0072] In the embodiment, when the core 31 breaks with the fragile portion 50 as the starting point, the coating resin 41 also breaks with the slit 49 as the starting point, but the present invention is not limited thereto, and the core 31 and the coating resin 41 may not break. In addition, even if the core 31 breaks with the fragile portion 50 as the starting point, the coating resin 41 may not break. In short, when an external force acts on the support shaft 30 and stress is applied to the fragile portion 50, the core 31 only needs to be at least broken with the fragile portion 50 as the starting point. Furthermore, when the core 31 breaks with the fragile portion 50 as the starting point, the coating resin 41 only needs to be at least broken with the slit 49 as the starting point.

[0073] In the embodiment, the edge 36 extends in a direction perpendicular to the axis of the first extension portion 32, but the invention is not limited thereto, and for example, the edge 36 may extend obliquely with respect to the axis of the first extension portion 32. In short, the edge 36 only needs to extend in a direction intersecting the axial direction of the first extension portion 32 of the cylindrical core 31.

[0074] In the embodiment, the slit 49 can expose the edge 36 of the concave portion 35 closer to the bent portion 34 to the outside. In this case, the edge 36 of the concave portion 35 closer to the bent portion 34 functions as the fragile portion 50.

[0075] In the embodiment, the fragile portion 50 is not limited to the edge 36 formed by crushing a part of the cylinder core 31. The fragile portion 50 may be, for example, the edge of a through hole formed in a part of the cylinder core 31, or may be an edge formed by providing a cutout in a part of the cylinder core 31. In short, the structure of the fragile portion 50 is not particularly limited.

[0076] In the embodiment, the locking portion 37 may not be provided on the cylindrical core 31 .

[0077] In the embodiment, only one recess 35 may be provided on the outer peripheral surface of the first extension portion 32. In short, the number of edges 36 formed on the cylindrical core 31 is not particularly limited. The number of slits 49 may be appropriately changed according to the number of edges 36.

[0078] In the embodiment, the vehicle compartment side surface 20 a of the vehicle body side fixing portion 20 may be, for example, a flat surface.

[0079] In the embodiment, the outer diameter of the locking head portion 47 is larger than the outer diameter of the small diameter portion 46 and smaller than the outer diameter of the large diameter portion 45, but the present invention is not limited thereto. In short, the shape of the portion of the first end of the support shaft 30 supported by the vehicle body side fixing portion 20 is not particularly limited. In other words, the first resin portion 42 is not limited to a structure having the large diameter portion 45, the small diameter portion 46, and the locking head portion 47.

[0080] In the embodiment, the vehicle body side fixing portion 20 may not have the locking claw 22. In this case, for example, a locking member may be separately provided at the second opening of the insertion hole 21, and the first end of the support shaft 30 may be locked to the locking member. According to this configuration, the support shaft 30 is supported by the vehicle body side fixing portion 20 by locking the first end of the support shaft 30 to the locking member.

[0081] In the embodiment, the sun visor body 11 may be solid. In short, the sun visor body 11 is not limited to a hollow shape.

[0082] In the embodiment, the shape of the sun visor body 11 may be changed appropriately.

[0083] In the embodiment, the material of the sun visor body 11 can be changed appropriately.
