[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-196969 [Patent Document 2] Patent Publication No. 2021-172217 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, if both the airbag module and the sunshade module are housed side by side in the roof side of a vehicle, the interior space of the roof side can be effectively used as installation space for both devices. However, when the airbag module and the sunshade module are placed adjacent to each other in the limited interior space of the roof side, some ingenuity is required to maintain the inflation and deployment performance of the airbag.

[0006] For example, a structure can be adopted in which the distance in the vehicle width direction between the airbag module and the interior member covering the sunshade module from the passenger compartment side is set large, taking into account the inflation range of the airbag. This structure can prevent the airbag from interfering with the interior member when it inflates and deploys. This is effective in preventing a decrease in the airbag inflation and deployment speed and damage to the interior member. However, this structure requires a large distance between the airbag module and the interior member, which limits the design freedom of the interior member. Therefore, there is a problem in that the design freedom of the interior member is sacrificed while maintaining the airbag's inflation and deployment performance.

[0007] The present invention has been made in consideration of such problems, and aims to provide a technology that is effective in improving the design freedom of interior components while maintaining the inflation and deployment performance of the airbag in a vehicle roof side structure that houses an airbag module and a sunshade module running side by side in the roof side portion of the vehicle. [Means for solving the problem]

[0008] One aspect of the present invention is an airbag module housed in a roof side portion of a vehicle; a sunshade module that is housed in the roof side portion parallel to the airbag module and located on the outer side of the vehicle than the airbag module; an interior member that covers the sunshade module from the vehicle interior side; Equipped with the airbag module has an airbag that inflates and deploys in a curtain shape along a side window portion of the vehicle, the sunshade module has a load receiving portion interposed between the airbag module and the interior member, and is configured to receive an input load from the airbag module at the load receiving portion when the airbag is inflated and deployed, the interior member is attached to the sunshade module and configured to move integrally with the sunshade module toward the vehicle exterior when the sunshade module receives the input load at the load receiving portion; is located. [Effects of the Invention]

[0009] In the vehicle roof side structure of the above aspect, the airbag module and the sunshade module are housed in the roof side portion so that they run parallel to each other, with the sunshade module positioned further outward than the airbag module. The sunshade module is provided with a load receiving portion interposed between the airbag module and an interior member that covers the sunshade module from the passenger compartment side. Therefore, the load receiving portion functions to receive an input load acting on the sunshade module from the airbag module when the sunshade module is inflated and deployed. At this time, the interior member is attached to and integrated with the sunshade module. Therefore, when the sunshade module receives the input load at the load receiving portion, the interior member moves toward the outside of the vehicle together with the sunshade module.

[0010] Here, by moving the interior member toward the outside of the vehicle together with the sunshade module, interference with the interior member during inflation and deployment of the airbag can be suppressed. This is therefore effective in preventing the interior member from reducing the airbag's inflation and deployment speed or damaging the airbag. Furthermore, by adopting a structure in which the interior member moves toward the outside of the vehicle together with the sunshade module, measures such as increasing the distance between the airbag module and the interior member in the vehicle width direction in order to maintain the airbag's inflation and deployment performance are not required. Therefore, while maintaining the airbag's inflation and deployment performance, it is possible to prevent restrictions on the design freedom of the interior member.

[0011] According to the above-described aspect, in a vehicle roof side structure in which an airbag module and a sunshade module are housed side by side in the roof side portion of a vehicle, it is possible to improve the design freedom of interior components while maintaining the inflation and deployment performance of the airbag.

[Figure 5] FIG. 5 is a cross-sectional view showing the airbag of FIG. 4 in a first operating state at the beginning of inflation and deployment. [Figure 6] FIG. 5 is a cross-sectional view showing the state when the airbag shown in FIG. 4 is in a second activated state. DETAILED DESCRIPTION OF THE INVENTION

[0013] Preferred embodiments of the above aspects are described below.

[0014] In this specification, "inflation" refers to the state in which the airbag expands due to the supply of gas to the internal space of the airbag, becoming larger than its state before the gas supply, and "deployment" refers to the state in which the airbag, which is pre-folded into a predetermined shape, expands so as to unfold as it inflates. In this way, the deployment of the airbag essentially involves inflation, and this state is called "inflation and deployment."

[0015] In the vehicle roof side structure of the above aspect, the sunshade module has a fixing portion for fixing to the roof side portion, The interior member is preferably configured to rotate integrally with the sunshade module toward the outside of the vehicle, with the fixing portion serving as a fulcrum.

[0016] With this vehicle roof side structure, the interior member can be rotated toward the outside of the vehicle in conjunction with the rotation of the sunshade module around the fixed portion relative to the roof side portion as a fulcrum, making it possible to easily move the interior member away from the airbag module.

[0017] In the vehicle roof side structure of the above aspect, the sunshade module has a sunshade case that accommodates the sunshade in a drawable manner, the airbag module has an airbag case that houses the airbag in a folded state, and the airbag case is provided with an airbag side wall portion that faces the sunshade case, The load-receiving portion is a sunshade side wall portion provided on the sunshade case so as to face the airbag side wall portion and extend parallel to the airbag side wall portion, and it is preferable that the sunshade side wall portion is configured to receive the input load from the airbag side wall portion.

[0018] According to this vehicle roof side structure, the sunshade case's side wall, which faces the airbag case's side wall, is used as a load-receiving portion. Because the sunshade side wall extends parallel to the airbag case's side wall, the input load from the airbag module is efficiently transmitted to the sunshade case via the airbag case's side wall and the sunshade side wall, and converted into a force that moves the sunshade case and interference member together toward the outside of the vehicle.

[0019] In the vehicle roof side structure of the above aspect, when the interior member is a first interior member, a second interior member is provided that is fixed to the roof side portion and is provided on the vehicle outer side of the first interior member, and an insertion opening for the sunshade is provided between the first interior member and the second interior member, It is preferable that the first interior member moves in a direction narrowing the gap toward the second interior member when moving integrally with the sunshade module toward the vehicle exterior.

[0020] With this vehicle roof side structure, the first interior member moves integrally with the sunshade module toward the second interior member in a direction narrowing the gap, and this space can be used as a movement allowance for the first interior member. This prevents the first interior member from interfering with the second interior member and hindering its movement toward the outside of the vehicle.

[0021] Hereinafter, specific examples of embodiments of the vehicle roof side structure will be described with reference to the drawings.

[0022] In the drawings used to explain this embodiment, the front of the vehicle is indicated by an arrow FR, the upper side of the vehicle is indicated by an arrow UP, and the inside of the vehicle is indicated by an arrow IN. Furthermore, unless otherwise specified, the vehicle length direction (front-rear direction) is indicated by an arrow X, the vehicle width direction (left-right direction) is indicated by an arrow Y, and the vehicle height direction (up-down direction) is indicated by an arrow Z.

[0023] (Embodiment 1) As shown in Fig. 1, a vehicle roof side structure (hereinafter simply referred to as "roof side structure") 101 of embodiment 1 is a structure that is mounted on each of the upper left and right roof side portions 2 of a vehicle 1. Since the left and right roof side structures 101 are identical, Fig. 1 exemplarily shows only the roof side structure 101 on the right side of the vehicle.

[0024] The roof side structure 101 includes an airbag module 10 and a sunshade module 20. Both the airbag module 10 and the sunshade module 20 are mounted on the vehicle 1 and provided along the roof side portion 2.

[0025] The interior space 2a of the roof side portion 2 is covered from the passenger compartment 8 side by multiple interior members, all made of synthetic resin material. The multiple interior members include an interior member 3 that covers the ceiling panel from the passenger compartment 8 side, an interior member 4 that covers the sunshade module 20 from the passenger compartment 8 side, and an interior member 5 (see FIG. 4) that is provided on the vehicle exterior side of the interior member 4. The interior members 4 and 5 are configured to extend parallel to each other in the vehicle length direction X. Generally, the interior member 3 is called a "roof headlining." The interior member 4 is also called an "inner rail garnish," and the interior member 5 is also called an "outer rail garnish."

[0026] 1. Structure of the airbag module 10 As shown in Fig. 1, an airbag module 10 is housed in a roof side portion 2 of a vehicle 1. The airbag module 10 is arranged in an internal space 2a of the roof side portion 2 so as to extend in the vehicle length direction X between an area above the side window portion 7a and an area above the side window portion 7c. The airbag module 10 includes an airbag 11, which is a curtain airbag that inflates and deploys in a curtain-like manner within the passenger compartment 8 along the side window portion 7.

[0027] The airbag 11 is arranged to cover the side windows 7 of the vehicle 1 like a curtain when fully inflated and deployed, and is used to protect the heads of occupants of the vehicle 1. The airbag 11 has a first airbag section 11a on the front side of the vehicle and a second airbag section 11b on the rear side of the vehicle, which is arranged rearward of the first airbag section 11a in the vehicle length direction X. The first airbag section 11a is configured to cover one side window section 7a of the side windows 7 corresponding to the front seats when fully inflated and deployed. On the other hand, the second airbag section 11b is configured to cover two side window sections 7b, 7c of the side windows 7 corresponding to the rear seats when fully inflated and deployed.

[0028] 2, the airbag module 10 includes an inflator 12 as a gas supply unit that supplies gas G for inflation and deployment to the airbag 11 when an impact occurs, and an airbag case 13 that houses the airbag 11 in a folded state. The inflator 12 and the airbag case 13 are housed in the internal space 2a of the roof side portion 2 together with the airbag 11.

[0029] The airbag 11 is an airbag-forming body formed by overlapping a plurality of sheet-like airbag fabrics and joining them by sewing, adhesive, etc. The airbag 11 has a plurality of fixing portions 11c, and is fixed to the framework of the roof side portion 2 by these fixing portions 11c.

[0030] The airbag 11 is in a folded state according to a predetermined procedure when housed in the airbag case 13 (see FIG. 4), and when gas G is supplied from the inflator 12 to the internal space of the airbag 11, the airbag 11 expands and unfolds, unfolding as it unfolds. At this time, the airbag 11 protrudes from the airbag case 13 toward the passenger compartment 8. Finally, the airbag 11 reaches a fully inflated and deployed state as shown in FIG.

[0031] 2. Structure of the sunshade module 20 3, the sunshade module 20 is housed in the roof side portion 2 running parallel to the airbag module 10 and located on the outer side of the vehicle in the vehicle width direction Y than the airbag module 10. The sunshade module 20 is arranged in the internal space 2a of the roof side portion 2 so as to extend along the vehicle length direction X in the region above only the side window portion 7c.

[0032] As shown in FIG. 3, the sunshade module 20 includes a sunshade 21, a winding shaft 22, a sunshade case 23, and a plurality of fixing portions 24.

[0033] The sunshade 21 is a sheet-like shielding member that is light-blocking and flexible, and is configured to be pulled out from the sunshade case 23 into the vehicle interior 8. The sunshade 21 is used as a sunshade that can block sunlight from outside the vehicle due to its light-blocking properties. In addition, the sunshade 21 is flexible so that it can be wound up around the outer circumferential surface of the winding shaft 22.

[0034] The winding shaft 22 is provided to wind up the sunshade 21 in a roll around the outer circumferential surface. The winding shaft 22 is rotatable around a support shaft 22a extending in the vehicle length direction X, and is configured to be constantly biased in the winding direction of the sunshade 21 by a biasing means (not shown) such as a spring member. The winding and unwinding operations of the sunshade 21 may be performed by an actuator such as an electric motor.

[0035] According to this configuration, the sunshade 21 can cover all or part of the side window portion 7c from the inside of the vehicle by being pulled downward in the vehicle height direction Z from the sunshade case 23 and held at an appropriate position. On the other hand, when the sunshade 21 is released from its holding position, it is pulled back upward and stops covering the side window portion 7c.

[0036] The sunshade module 20 of this embodiment is designed to be used by pulling down the sunshade 21 from the sunshade case 23 housed in the roof side portion 2, which provides the following advantages: The sunshade 21 allows the driver and passenger to enjoy the scenery outside the vehicle while adjusting the amount of sunlight entering through the sunshade 21. Passengers can stop the sunshade 21 in its opening depending on the amount of sunlight entering through the vehicle, allowing them to enjoy the scenery.

[0037] 3, the sunshade case 23 accommodates the sunshade 21 so that it can be pulled out downward in the vehicle height direction Z, and is configured as a housing member that accommodates the winding shaft 22. Both ends of the sunshade case 23 in the vehicle length direction X are fastened and fixed to the framework of the roof side section 2 by fixing parts 24 made of bolt members. Therefore, the fixing parts 24 serve as fixing parts for the sunshade module 20 to the roof side section 2.

[0038] 4, the airbag case 13 is provided with an airbag side wall 13a that faces the sunshade case 23. Only the airbag side wall 13a and no other member are interposed between the airbag 11 in the pre-folded initial state C0 and the sunshade case 23. A lower end 13b of this airbag side wall 13a extends to the vicinity of the interior member 3.

[0039] On the other hand, the sunshade case 23 is provided with a sunshade side wall 23a. This sunshade side wall 23a is configured to face the airbag side wall 13a of the airbag case 13 and extend parallel to the airbag side wall 13a. This sunshade side wall 23a is interposed between the airbag module 10 and the interior member 4 and constitutes a load-receiving portion that receives an input load from the airbag module 10. The sunshade side wall 23a receives the input load from the airbag side wall 13a. For this reason, in the following description, this sunshade side wall 23a will also be referred to as the "load-receiving portion 23a."

[0040] 3. Structure of interior member 4 As shown in FIG. 3, the interior member 4 extends in the vehicle length direction X along the sunshade case 23 below the sunshade case 23. The interior member 4 is attached to the sunshade module 20, but is not attached to the framework of the roof side portion 2. Specifically, the interior member 4 has a plurality of attachment portions 4a at its upper portion, and a plurality of attachment receiving portions 23b at its lower portion, each corresponding to one of the attachment portions 4a. The attachment portions 4a and the attachment receiving portions 23b are all located inward of the two fixing portions 24. The attachment portions 4a of the interior member 4 and the attachment receiving portions 23b of the sunshade case 23 are connected to each other by a fixing member 6 (see FIG. 4), such as a clip. Thus, the interior member 4 is fixed integrally to the sunshade case 23 via the attachment portions 4a and the attachment receiving portions 23b.

[0041] As shown in Fig. 4, a gap 5a for inserting the sunshade 21 is provided below the sunshade case 23. The sunshade 21 pulled out from the sunshade case 23 extends through this gap 5a to the passenger compartment 8. Here, the gap 5a is provided between the interior member 4 (first interior member) and the interior member 5 (interior member). That is, the gap 5a is defined and formed by the outer end surface of the interior member 4 and the inner end surface of the interior member 5. The interior member 5 is fixed to the framework of the roof side portion 2.

[0042] Additionally, this interior member 4 is arranged so that its inner end 4b overlaps the lower end of the interior member 3. At this time, the separation distance L in the vehicle width direction Y between the inner end 4b and the lower end 13b of the airbag side wall portion 13a can be set appropriately according to the design of the interior member 4.

[0043] 4. Inflation and deployment of airbag 11 Next, with reference to FIGS. 2 and 4 to 6, the inflation and deployment operation of the airbag 11 when it is inflated and deployed upon the occurrence of an impact will be described.

[0044] 2, when a large impact is applied to a sensor (not shown) disposed in the vehicle 1 in the event of a collision or the like of the vehicle 1, the two inflators 12 are activated and generate gas G at approximately the same time. The gas G generated by the two inflators 12 is supplied to the internal spaces of the first airbag portion 11a and the second airbag portion 11b of the airbag 11, respectively.

[0045] At this time, the second airbag portion 11b of the airbag 11 changes from the initial state C0 (see FIG. 4) to a first activated state C1 (see FIG. 5) at the beginning of inflation and deployment in accordance with the activation of the inflator 12. As shown in FIG. 5, during the process in which the second airbag portion 11b of the airbag 11 changes to the first activated state C1, the interior member 3 is pushed open toward the passenger compartment 8 by the load received from the second airbag portion 11b. As a result, the interior member 3 is partially released from the covering state, and the second airbag portion 11b becomes able to protrude toward the passenger compartment 8.

[0046] As shown in Figure 5, when the second airbag portion 11b of the airbag 11 enters the first activated state C1, the airbag side wall portion 13a of the airbag case 13 moves toward the vehicle exterior until it contacts the sunshade side wall portion 23a of the sunshade case 23. At this time, the sunshade side wall portion 23a of the sunshade case 23 begins to receive the input load F from the airbag module 10 via the airbag side wall portion 13a of the airbag case 13. Thereafter, as the inflation and deployment operation of the airbag 11 progresses, the airbag side wall portion 13a moves toward the vehicle exterior against the reaction force received from the sunshade side wall portion 23a. The input load F received by the sunshade side wall portion 23a increases as the inflation and deployment operation of the airbag 11 progresses.

[0047] In this embodiment, the sunshade side wall 23a is not in direct contact with the second airbag portion 11b of the airbag 11, but is in direct contact with the airbag side wall 13a pressed by the second airbag portion 11b. Alternatively, a structure in which the sunshade side wall 23a is in direct contact with the second airbag portion 11b may be adopted instead.

[0048] As shown in Fig. 6, the second airbag portion 11b of the airbag 11 changes from the first activated state C1 to the second activated state C2 as the inflation and deployment operation progresses further. At this time, the sunshade case 23 is fixed to the framework of the roof side portion 2 by the fixing portion 24. Therefore, the sunshade case 23 rotates in a rotation direction R toward the outside of the vehicle, with the fixing portion 24 as a fulcrum, in accordance with the input load F from the airbag module 10. At this time, the position of the sunshade case 23 changes from a first position P1 (see the position indicated by the two-dot chain line in Fig. 6) to a second position P2 (see the position indicated by the solid line in Fig. 6).

[0049] In this embodiment, the interior member 4 is attached to and integrated with the sunshade case 23 of the sunshade module 20. Therefore, when the sunshade case 23 receives an input load F at the sunshade side wall portion 23a during inflation and deployment of the second airbag portion 11b of the airbag 11, the interior member 4 moves integrally with the sunshade case 23 toward the outside of the vehicle. At this time, similar to the sunshade module 20, the interior member 4 rotates integrally with the sunshade module in the rotation direction R with the fixing portion 24 as a fulcrum. At this time, the position of the interior member 4 changes from a first position Q1 (see the position indicated by the two-dot chain line in FIG. 6) to a second position Q2 (see the position indicated by the solid line in FIG. 6).

[0050] Here, the interior member 4 is fixed to the sunshade case 23, while the interior member 5 is fixed to the roof side portion 2. Therefore, when the interior member 4 moves integrally with the sunshade module 20 and its position changes from the first position Q1 to the second position Q2, the movable interior member 4 moves toward the fixed interior member 5 in a direction narrowing the gap 5a. The interior member 4 can move toward the outside of the vehicle without interfering with other members until the gap 5a disappears and the interior member 4 interferes with the interior member 5. Therefore, the gap 5a can be used as a movement allowance for the interior member 4 toward the outside of the vehicle.

[0051] As the interior member 4 moves from the first position Q1 to the second position Q2, the inner end 4b thereof moves in a direction away from or in a direction away from the airbag module 10. This prevents the second airbag portion 11b from interfering with the inner end 4b of the interior member 4 when the airbag 11 is inflated and deployed. Therefore, it is possible to prevent the second airbag portion 11b from getting caught on the inner end 4b of the interior member 4 and interfering with the inflation and deployment action.

[0052] Thereafter, the second airbag portion 11b of the airbag 11 continues to inflate and deploy from the second activated state C2 shown in FIG. 6, and finally reaches the fully inflated and deployed state shown in FIG.

[0053] According to the above-described first embodiment, the following effects can be obtained.

[0054] In the roof side structure 101 of the first embodiment, the airbag module 10 and the sunshade module 20 are housed in the roof side portion 2 so as to run parallel to each other, with the sunshade module 20 positioned closer to the vehicle exterior than the airbag module 10. The sunshade module 20 is provided with a load receiving portion 23a that is interposed between the airbag module 10 and an interior member 4 that covers the sunshade module 20 from the vehicle interior 8 side. Therefore, the load receiving portion 23a functions to receive an input load F that acts on the sunshade module 20 from the airbag module 10 when the sunshade module 20 is inflated and deployed. At this time, the interior member 4 is attached to and integrated with the sunshade module 20. Therefore, when the sunshade module 20 receives the input load F at the load receiving portion 23a, the interior member 4 moves integrally with the sunshade module 20 toward the vehicle exterior.

[0055] Here, by moving the interior member 4 toward the outside of the vehicle together with the sunshade module 20, it is possible to prevent the airbag 11 from interfering with this interior member 4 when it inflates and deploys. This is therefore effective in preventing the inflation and deployment speed of the airbag 11 from being reduced due to the influence of the interior member 4 and preventing the interior member 4 from being damaged. Furthermore, if a structure is adopted in which the interior member 4 moves toward the outside of the vehicle together with the sunshade module 20, it is not necessary to take measures such as increasing the separation distance L (see Figure 4) between the airbag module 10 and the interior member 4 in the vehicle width direction Y in order to maintain the inflation and deployment performance of the airbag 11. Therefore, it is possible to prevent restrictions on the design freedom of the interior member 4, provided that the inflation and deployment performance of the airbag 11 is maintained.

[0056] Therefore, according to the above-described embodiment 1, in the vehicle roof side structure 101 that houses the airbag module 10 and the sunshade module 20 running side by side in the roof side portion 2 of the vehicle 1, it is possible to improve the design freedom of the interior member 4 while maintaining the inflation and deployment performance of the airbag 11.

[0057] According to the roof side structure 101 of the first embodiment, the interior member 4 can be moved to the outside of the vehicle by simply attaching the interior member 4 to the sunshade case 23, which prevents the structure from becoming complicated and is effective in preventing the need for dedicated parts other than existing parts.

[0058] According to the roof side structure 101 of the first embodiment, the interior member 4 can be rotated toward the outside of the vehicle in conjunction with the rotation of the sunshade module 20 around the fixed portion 24 relative to the roof side portion 2. This makes it possible to easily move the interior member 4 in a direction away from the airbag module 10.

[0059] According to the roof side structure 101 of the first embodiment, the sunshade side wall 23a of the sunshade case 23 that faces the airbag side wall 13a of the airbag case 13 is used as a load-receiving portion. At this time, because the sunshade side wall 23a extends parallel to the airbag side wall 13a, the input load F from the airbag module 10 is efficiently transmitted to the sunshade case 23 side via the airbag side wall 13a and the sunshade side wall 23a, and can be converted into a force that moves the sunshade case 23 and the interior member 4 together toward the outside of the vehicle.

[0060] According to the roof side structure 101 of the first embodiment, the interior member 4 moves integrally with the sunshade module 20 toward the interior member 5 in a direction narrowing the gap 5a, and the space of this gap 5a can be used as a movement allowance for the interior member 4. This makes it possible to prevent the interior member 4 from interfering with the interior member 5 and hindering its movement toward the outside of the vehicle.

[0061] The present invention is not limited to the exemplary embodiments described above, and various applications and modifications are possible without departing from the scope of the present invention. For example, the following embodiments can be implemented by applying the above embodiments.

[0062] In the above embodiment, an example is given of the case where the interior member 4 and the sunshade module 20 rotate integrally toward the outside of the vehicle when the sunshade module 20 receives the input load F at the load receiving portion 23a. However, the movement of the interior member 4 and the sunshade module 20 moving integrally toward the outside of the vehicle is not limited to rotation, and they may move, for example, by sliding linearly.

[0063] In the above embodiment, an example was given of the case where the sunshade side wall portion 23a, which is part of the sunshade case 23 of the sunshade module 20, is used as the load-receiving portion, but instead, the load-receiving portion may be formed by an element of the sunshade module 20 other than the sunshade case 23 (for example, a separate member attached to the sunshade case 23).

[0064] In the above embodiment, a structure in which the sunshade module 20 is provided only in the upper region of the side window portion 7c of the vehicle 1 has been exemplified, but in addition to or instead of this structure, a structure similar to the sunshade module 20 may be provided in the upper region of the side window portion 7a or the upper region of the side window portion 7b.
