Description

  The present invention relates to a vehicle sun visor. In particular, the present invention relates to a configuration of a vehicle sun visor in which a sun visor body is rotatably supported by a shaft, and a method of forming a shaft of the vehicle sun visor.

  A vehicle sun visor is provided to be stored in an upper part in front of the vehicle interior of the vehicle, rotatably supported by a shaft, and to shield glare from the front or side. Some vehicles include an air bag in a front pillar or the like near the vehicle sun visor. Therefore, the passenger can be protected by deploying the airbag due to a vehicle collision.

  When the air bag near the vehicle sun visor is deployed, the air bag collides with the vehicle sun visor, and the impact of the collision causes the stress to concentrate on the bent part of the shaft of the vehicle sun visor, causing deformation and the deformation of the bent part of the shaft. Since the resin is broken and fragments are scattered in the passenger compartment, measures have been taken conventionally.

In Patent Document 1, a brittle portion is provided on a surface where two types of resins are in contact with each other by covering two different types of coating resins around a metal pipe positioned at the center of the pipe constituting the shaft. By making the fragile part easily bend and deform due to the impact applied, the position of the bend deformation is limited and the load energy is preferentially consumed to prevent the resin from cracking and scattering of fragments. A vehicle sun visor is provided.
JP 2005-119477 A

  In Patent Document 1, a hard resin is used to maintain the strength of the shaft on the fixed bracket side that is fixed above the passenger compartment and the support side that supports the sun visor body, and a soft resin is applied to the bent portion where stress is concentrated. By using, it is possible to reduce the occurrence of scattering due to the breakage of the resin when bending deformation occurs in the bent portion, but it costs because it is molded using two types of resins. In addition, when molded with one type of resin, there is no use other than using a hard resin to maintain the strength of the shaft, and if stress is applied and the bent part is bent and deformed, it will scatter due to the breakage of the resin .

  Accordingly, the present invention has been made in view of the above circumstances, and provides a vehicle sun visor and a method for forming a shaft of a vehicle sun visor, which prevent the resin from rupturing from the shaft of the sun visor against air bag deployment. The purpose is to do.

  In order to solve the above-described problems, a vehicle sun visor according to the present invention includes a bracket fixed to a vehicle body, a shaft rotatably supported on the bracket, and a support that holds the sun visor body by inserting the shaft. In the vehicle sun visor, the shaft is inserted into the support and includes a groove portion provided in the sun visor main body and substantially in the center with respect to the entire length of the shaft. The groove portion is formed by the vehicle sun visor. When receiving an impact from an air bag, the groove is bent.

  According to this configuration, by inserting the shaft into the support and providing a groove in the shaft at the position where the sun visor main body is located, the groove is provided in the inner portion of the sun visor main body of the shaft. The impact can be suppressed by concentrating the stress in the groove portion and positively bending the groove. Also, in the groove where stress is concentrated, the resin of the shaft breaks due to bending deformation, but since the groove is an internal part of the sun visor main body, the resin debris is scattered only in the sun visor main body. Can be prevented from scattering. In addition, by providing a groove part in the approximate center with respect to the entire length of the shaft, the rotational movement in the vehicle compartment direction centered on the bracket fixed to the vehicle compartment due to the impact on the shaft is Therefore, the turning radius is reduced and the centrifugal force applied to the sun visor body is reduced. Therefore, the centripetal force applied to the bent portion is reduced, and breakage due to the resin at the bent portion can be suppressed.

  Further, in addition to the above-mentioned invention, the shaft includes a metal pipe portion located in the center, and a resin portion formed by covering the pipe portion with a thermoplastic resin by an injection molding machine, and the groove portion. Is rotated perpendicularly to the resin portion in the longitudinal direction of the shaft at two opposing positions which turn the sun visor body to the vehicle side surface and are used as a side visor on the vehicle inner side and the vehicle cabin outer side. It is provided in the direction.

  According to this configuration, the shaft is a molded product in which the pipe is covered with a thermoplastic resin, and the sun visor body is rotated to the side of the vehicle on the resin portion of the shaft. Since the grooves are provided in two opposite locations on the outside of the passenger compartment in the direction perpendicular to the resin portion in the longitudinal direction of the shaft, stress is actively applied to the grooves against the impact on the sun visor caused by the airbag deployment. When the bending is performed by concentrating, the bending direction can be restricted. Further, by providing the groove portions at two opposing positions, one can be expanded in the vehicle width direction due to the ductility of the metal pipe when bent, and the metal pipe can be easily condensed in the vehicle width direction when the other is bent. . Further, by reducing the amount of the coating resin of the resin portion in the two groove portions, the resin scattered at the time of bending can be reduced.

  Further, in order to solve the above-described problem, a method for forming a shaft of a vehicle sun visor according to the present invention is provided substantially at the center with respect to the entire length of the metal pipe portion, and faces 2 on the side surface of the metal pipe portion. A step of holding the metal pipe portion by a holding portion which is a location, a molten resin in which the metal pipe portion is positioned and fixed in the cavity, and the thermoplastic resin is melted in the cavity And forming a shaft by forming the resin part by solidifying the molten resin around the metal pipe part, and forming a groove part by solidifying the molten resin without flowing into the holding part. And the groove portion has an intrinsic function in the sun visor body when the molded shaft is inserted into a support for holding the sun visor body. The resin in the longitudinal direction of the shaft is located at two positions facing the vehicle inner side and the vehicle compartment outer side of the shaft when the sun visor body is rotated to the vehicle side surface side and used as a side visor. It is characterized by being provided in a direction perpendicular to the part.

  According to this forming method, since the holding portion for holding the metal pipe portion at the time of forming the shaft is provided substantially at the center with respect to the entire length of the shaft, the position of the shaft in the longitudinal direction during the forming of the shaft The width can be reduced. Moreover, since it hold | maintains at the holding part which is two positions which oppose in the side surface of a metal pipe part, the position regulation of the plate | board thickness direction of a shaft can be performed. In other words, it is possible to restrict the position so that the metal pipe portion is positioned at the center of the resin portion covering the periphery of the metal pipe portion, thereby reducing the deflection width. For this reason, the precision of the thickness of the coating resin of the shaft can be increased, and the quality of the product can be improved. At the same time, this holding portion is utilized as a groove portion that is not covered with resin when the shaft is molded, so that it is not necessary to provide a groove portion separately from the holding portion, and the cost can be reduced. In addition, since the groove is an internal part of the sun visor main body, stress is concentrated in the groove to positively bend the impact on the sun visor due to the airbag deployment, and resin fragments are scattered only on the sun visor main body. Therefore, it is possible to prevent resin fragments from being scattered in the vehicle interior.

  ADVANTAGE OF THE INVENTION According to this invention, the formation of the shaft of the vehicle sun visor and the vehicle sun visor for preventing the scattering due to the breakage of the resin from the shaft of the sun visor against the deployment of the air bag by providing the groove portion in the inner portion of the sun visor body of the shaft A method can be provided.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Embodiments of the invention will be described below with reference to the accompanying drawings. The vehicle sun visor according to the embodiment of the present invention will be described as a vehicle sun visor pivotally supported by a shaft.

  Accordingly, two examples of the embodiment according to the present invention will be described with reference to the drawings with reference to FIGS.

  1 to 4 show Example 1 of a vehicle sun visor according to an embodiment of the present invention. Hereinafter, the configuration of the vehicle sun visor according to the first embodiment will be described.

  1 and 2 are configuration diagrams schematically showing a vehicle sun visor according to a first embodiment of the present invention. Moreover, it is a state in which the passenger uses the vehicle sun visor 1 and is viewed from the front of the vehicle from the passenger compartment side.

  As shown in FIGS. 1 and 2, the vehicle sun visor 1 includes a sun visor body 2, a shaft 3 that rotatably supports the sun visor body 2, and a support 4 that supports the sun visor body 2 by inserting the shaft 3 therein. The support 4 and the iron clip 5 for fixing the shaft 3 inserted in the support 4 and the vehicle compartment fixing bracket 10 for locking the shaft 3 to the vehicle compartment side and supporting the shaft.

  Since one end of the shaft 3 is pivotally supported by the vehicle interior fixing bracket 10, the shaft 3 can rotate with respect to a vertical axis passing through the vehicle interior fixing bracket 10. Therefore, the sun visor main body 2 on the vehicle front side can be turned to the vehicle side surface and used as a side visor. Further, since the other end of the shaft 3 supports a support 4 fixed to the sun visor body 2, the sun visor body 2 can be rotated in the vertical direction around the shaft 3. Therefore, when the vehicle sun visor 1 is used, the sun visor body 2 is rotated downward to block glare from the front or side of the vehicle. Further, when the vehicle sun visor 1 is not used, the sun visor main body 2 can be rotated upward to be stored above the vehicle.

  FIG. 3 is a configuration diagram schematically showing the shaft 3 of the vehicle sun visor 1 according to the first embodiment of the present invention. FIG. 3 shows a state in which the occupant is using the vehicle sun visor 1, and is a configuration diagram showing from the passenger compartment side to the vehicle front side or the vehicle side side. Moreover, the iron clip 5 is abbreviate | omitted for description.

  As shown in FIG. 3, the shaft 3 includes a terminal end portion 11 that is pivotally supported by the vehicle interior fixing bracket 10 and a bent portion that is bent at approximately 90 degrees before being inserted into the support 4 at the tip of the terminal end portion 11. 12, an insertion portion 13 to be inserted into the support 4, a locking portion 14 that is locked to one support 4 at the end of the insertion portion, and a tip of the insertion portion that penetrates the support 4. It is comprised by the other end of the support 4 and the securing part 15 latched.

  The shaft 3 is a molded product composed of a resin portion 19 having a metal pipe 16 as a central core and the periphery covered with a coating resin. Further, in the approximate center of the shaft 3, the sun visor main body 2 is rotated to the vehicle side surface side, and when used as a side visor, the shaft 3 is positioned at two positions facing the vehicle inner side and the vehicle compartment outer side in the longitudinal direction of the shaft 3. A groove portion 17 is provided in a direction perpendicular to the resin portion 19.

  FIG. 4 is a configuration diagram schematically showing the shaft 3 of the vehicle sun visor 1 according to the first embodiment of the present invention. FIG. 4A is a detailed view schematically showing the groove portion 17 provided in the shaft 3. FIG. 4B is a cross-sectional view schematically showing the groove portion 17 provided in the shaft 3.

  As shown in FIGS. 4A and 4B, the groove portion 17 is provided at the position of the insertion portion 13 of the shaft 3 that is substantially the center of the shaft 3, and rotates the sun visor body 2 toward the vehicle side surface. When used as a side visor, the shaft 3 is provided at two opposite positions on the vehicle inner side and the vehicle compartment outer side in two directions perpendicular to the resin portion 19 in the longitudinal direction of the shaft 3. In addition, although the resin part 19 is provided in the groove part 17, the thickness of the coating resin is thinner than parts other than the groove part 17. However, since the pipe 16 is reliably covered with the resin portion 19, the pipe 16 can be rust-prevented even in the groove portion 17.

  Hereinafter, effects of the vehicle sun visor 1 according to the first embodiment will be described.

  When the sun visor body 2 receives a large impact developed by an airbag (not shown), the sun visor body 2 is caused by the impact of the airbag, particularly when the sun visor body 2 is rotated to the side of the vehicle and used as a side visor. Rotational force about the vertical direction of the shaft 3 is applied, and the shaft 3 is rotated toward the passenger compartment side at a violent speed. Therefore, a strong centrifugal force is applied to the end face on the side farther from the shaft 3 in the sun visor body 2. Since the sun visor body 2 is a foam-molded product made of PP beads, it has the effect of greatly absorbing the impact caused by the development of the airbag and suppressing the rotational force and centrifugal force described above. However, the sun visor body 2 still rotates toward the passenger compartment where the passenger is present.

  Therefore, a groove portion 17 is provided at a position substantially at the center of the shaft 3, and the groove portion 17 is opposed to the vehicle inner side of the shaft 3 and the vehicle compartment outer side when the sun visor body 2 is rotated to the vehicle side surface side and used as a side visor. By providing it at two locations, the stress generated in the groove portion 17 due to the impact of the airbag can be concentrated and the resin portion 19 can be easily broken. Moreover, the groove part 17 into which the resin part 19 breaks becomes the inside of the sun visor main body 2, and it is possible to prevent the resin fragments from being scattered in the vehicle interior. Further, since the collision energy when the airbag is deployed is consumed as a force for deforming the groove portion 17 and a force for breaking the resin portion 19 around the groove portion 17, the force for rotating the sun visor body 2 toward the vehicle compartment side is reduced. Can do.

  Further, since the resin portion 19 of the groove portion 17 is broken and the shaft 3 is bent around the groove portion 17, the turning radius of the shaft 3 is reduced and the centrifugal force is also reduced. Therefore, it is possible to reduce the force with which the sun visor main body 2 rotates toward the passenger compartment.

  According to Example 1 of the present embodiment, the shaft 3 is inserted into the support 4 and the groove portion 17 is provided in the shaft 3 at a position to be the insertion portion 13 of the sun visor main body 2, so that the sun visor main body 2 by air bag deployment is provided. The impact can be suppressed by concentrating the stress in the groove portion 17 and positively bending it. Further, in the groove portion 17 where the stress is concentrated, the resin of the shaft 3 is broken due to the bending deformation. However, since the groove portion 17 is the insertion portion 13 of the sun visor body 2, resin fragments are scattered only in the sun visor body 2. It is possible to prevent resin fragments from being scattered in the vehicle interior. Further, by providing the groove portion 17 substantially at the center with respect to the entire length of the shaft 3, the rotational movement in the vehicle interior direction around the vehicle interior fixing bracket 10 fixed to the vehicle interior due to the impact applied to the shaft 3 is caused by the groove portion. Since the movement moves toward the passenger compartment around 17, the turning radius is reduced and the centrifugal force applied to the sun visor body 2 is reduced. Therefore, the centripetal force applied to the bent portion 12 is reduced, and breakage due to the resin at the bent portion 12 can be suppressed.

  Further, according to Example 1 of the present embodiment, the shaft 3 is a molded product in which a thermoplastic resin is covered around the pipe, and the sun visor main body 2 is rotated toward the vehicle side by the resin portion 19 of the shaft 3. Since the groove portions 17 are provided in two perpendicular directions with respect to the resin portion 19 in the longitudinal direction of the shaft 3 at two opposite positions on the shaft 3 on the vehicle inner side and the vehicle compartment outer side when used as a side visor. When bending is performed by positively concentrating stress in the groove portion 17 with respect to the impact on the sun visor body 2, the direction of bending can be restricted. Further, by providing the groove portions 17 at two opposing positions, one can be expanded in the vehicle width direction due to the ductility of the pipe 16 when bent, and the pipe 16 can be easily condensed in the vehicle width direction when the other is bent. Further, by reducing the amount of the coating resin of the resin portion 19 in the two groove portions 17, the resin scattered at the time of bending can be reduced.

  As described above, according to Example 1 of the present embodiment, the shaft 3 is inserted into the support 4 and the groove portion 17 is provided in the shaft 3 at the position to be the insertion portion 13 of the sun visor main body 2. On the other hand, it is possible to provide a vehicle sun visor that prevents scattering due to resin breakage from the shaft 3 of the sun visor.

  Next, Example 2 of the vehicle sun visor according to this embodiment of the present invention will be described. Hereinafter, the configuration of the vehicle sun visor according to the second embodiment will be described.

  5 and 6 show Example 2 of the vehicle sun visor according to the embodiment of the present invention. Hereinafter, the configuration of the vehicle sun visor and the shaft forming method according to the second embodiment will be described. The description of the same configuration as that of the first embodiment will be omitted.

FIG. 5 shows a state in which the occupant is using the vehicle sun visor 1, and is a configuration diagram shown from the passenger compartment side to the vehicle front side or the vehicle side side. Moreover, the iron clip 5 is abbreviate | omitted for description.

  As shown in FIG. 5, since one end of the shaft 3 is pivotally supported by the vehicle compartment fixing bracket 10, the shaft 3 can rotate with respect to a vertical axis passing through the vehicle compartment fixing bracket 10. . Therefore, the sun visor main body 2 on the vehicle front side can be turned to the vehicle side surface and used as a side visor. Further, since the other end of the shaft 3 supports a support 4 fixed to the sun visor body 2, the sun visor body 2 can be rotated in the vertical direction around the shaft 3. Therefore, when the vehicle sun visor 1 is used, the sun visor body 2 is rotated downward to block glare from the front or side of the vehicle. Further, when the vehicle sun visor 1 is not used, the sun visor main body 2 can be rotated upward to be stored above the vehicle.

  Further, the shaft 3 includes an end portion 11 in the vicinity of being pivotally supported by the vehicle interior fixing bracket 10, a bent portion 12 bent at approximately 90 degrees before being inserted into the support 4 at the end of the end portion 11, and a support. An insertion portion 13 to be inserted into 4, a locking portion 14 locked to one support 4 at the end of the insertion portion, and the support 4 at the tip of the insertion portion through the support 4. It is comprised by the securing part 15 latched with one end.

  The shaft 3 is a molded product composed of a resin portion 19 having a metal pipe 16 as a central core and the periphery covered with a coating resin. Further, in the approximate center of the shaft 3, the sun visor main body 2 is rotated to the vehicle side surface side, and when used as a side visor, the shaft 3 is positioned at two positions facing the vehicle inner side and the vehicle compartment outer side in the longitudinal direction of the shaft 3. A groove portion 18 is provided in a direction perpendicular to the resin portion 19. The groove 18 has a depth that allows the pipe 16 to be seen.

  FIG. 6 is an explanatory view schematically showing a method of forming the shaft 3 of the vehicle sun visor 1 according to the second embodiment of the present invention. FIG. 6A shows a locate position when the shaft 3 is resin-molded. FIG. 6B is a cross-sectional view showing the state of the shaft molded with resin by a mold.

  As shown in FIGS. 6A and 6B, when the shaft 3 is formed, the locating pins 21 are inserted and fixed to both ends of the L-shaped metal pipe 16 in the cavity 20, The additional locate 22 is also provided at a position that is substantially in the center with respect to the entire length of the pipe 16, and the pipe 16 is positioned and held. At this time, the holding portions for holding the pipe 16 by the additional locator 22 are provided at two opposing positions on the side surface of the pipe 16 as shown in FIG.

  Next, a molten resin obtained by melting a thermoplastic resin is poured into the cavity 20 to solidify the dissolved resin using the pipe 16 as a central core material to form a resin portion 19 having a predetermined shape. At this time, since the molten resin does not flow into the holding portion held by the additional locator 22, a groove portion 18 as shown in FIG. 6B is formed.

  As shown in FIG. 5, the molded shaft 3 has a structure in which a shaft groove portion 18 is provided at a position to be an insertion portion 13 to be inserted into the support 4. Further, the sun visor body 2 is attached to the shaft 3. When used as a side visor by turning to the side surface of the vehicle, groove portions 18 come in the vertical direction with respect to the resin portion 19 in the longitudinal direction of the shaft 3 at two opposed positions on the vehicle inner side and the vehicle cabin outer side of the shaft 3. It is configured as follows.

  Since the vehicle sun visor according to the second embodiment of the present embodiment is configured as described above, substantially the same operations and effects as the vehicle sun visor according to the first embodiment can be achieved.

  Furthermore, in Example 2 of the present embodiment, the holding portion for holding the metal pipe 16 at the time of molding the shaft 3 is provided at the substantially center with respect to the entire length of the shaft 3, so The deflection width at the position in the longitudinal direction of the shaft 3 can be reduced. Moreover, since it hold | maintains at the holding | maintenance part which is the position of 2 places which opposes in the side surface of the metal pipe 16, position control of the thickness direction of the shaft 3 can be performed. In other words, the position of the metal pipe 16 can be regulated so as to be positioned at the center of the resin portion 19 covering the periphery thereof, and the deflection width can be reduced. For this reason, the precision of the plate | board thickness of the coating resin of the shaft 3 can be improved, and the quality of a product can be improved. At the same time, when the holding portion is used as the groove portion 18 not covered with the resin portion 19 when the shaft 3 is molded, it is not necessary to provide a groove portion separately from the holding portion, and the cost can be reduced. Further, since the groove portion 18 is the insertion portion 13 of the sun visor body 2, stress is concentrated on the groove portion 18 in response to the impact on the sun visor due to the airbag deployment, and the resin shards are made to bend positively. Since it scatters only to the main body 2, it is possible to prevent resin fragments from being scattered in the vehicle interior.

  As described above, according to Example 2 of the present embodiment, the shaft 3 is inserted into the support 4 and the groove portion 17 is provided in the shaft 3 at the position that becomes the insertion portion 13 of the sun visor main body 2.
