Description

[Technical Field]

[0001] The present specification discloses a vehicle side structure including a window formed in a side wall of a vehicle and a curtain airbag device provided above the window. [Background technology]

[0002] Conventionally, curtain airbag devices have been known that protect occupants by inflating and deploying between a vehicle side window and the occupant in the event of a side collision. For example, Patent Document 1 discloses a vehicle curtain airbag device having a curtain airbag that inflates and deploys downward along the side window glass of the vehicle. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-059329 Summary of the Invention [Problem to be solved by the invention]

[0004] In the event of a vehicle collision, the window glass covering the window opening may break, opening the window. In this case, there is a risk that the inflated and deployed curtain airbag may fly out of the vehicle through the window opening. Therefore, curtain airbags are typically sized so that a portion of the curtain airbag overlaps with the door trim in the vehicle width direction when inflated and deployed. With this configuration, even if the curtain airbag tries to fly out of the vehicle through the window opening, a portion of the curtain airbag gets caught on the door trim, preventing the curtain airbag from flying out of the vehicle.

[0005] However, in order to overlap a portion of the curtain airbag with the door trim in the vehicle width direction, it is necessary to either increase the size of the curtain airbag or position the upper edge of the trim, i.e., the lower edge of the window opening, higher. In the former case, however, there is a problem that the cost required for the curtain airbag device increases. In the latter case, if the lower edge of the window opening is positioned higher, the window opening becomes smaller accordingly, limiting the field of view for observing the outside of the vehicle.

[0006] Patent Document 1 discloses a technology in which a tension member is attached to the surface of a curtain airbag, the tension member extending rearward and downward from near the front upper corner to near the bottom end of the curtain airbag when the curtain airbag is inflated and deployed. By providing such a tension member, the curtain airbag can be maintained in a taut state, preventing it from being ejected outside the vehicle. However, since Patent Document 1 attaches a tension member to the curtain airbag, another problem occurs in that the curtain airbag becomes large in its folded state. Furthermore, providing a tension member increases the cost required for the curtain airbag device.

[0007] Therefore, this specification discloses a vehicle side structure that can prevent a curtain airbag from jumping out of the vehicle while suppressing both an increase in cost and a restriction on visibility. [Means for solving the problem]

[0008] The vehicle side structure disclosed in this specification comprises a window having a window opening provided in a side wall of the vehicle and window glass covering the window opening, a curtain airbag device attached above the window and having a curtain airbag that can inflate downward, and a bar-shaped member that divides the window opening into upper and lower sections when viewed from the side of the vehicle, wherein the bar-shaped member is provided inside the window opening or inward in the vehicle width direction from the window opening and outward in the vehicle width direction from the curtain airbag when fully inflated, and at least a portion of the fully inflated curtain airbag extends below the bar-shaped member.

[0009] With this configuration, even if a fully inflated curtain airbag attempts to fly out of the vehicle through a window opening, it gets caught on the bar-shaped member, effectively preventing the curtain airbag from flying out of the vehicle. Furthermore, this type of curtain airbag getting caught on the bar-shaped member occurs even if the curtain airbag is smaller than the window opening or if the lower edge of the window opening is positioned low. Therefore, with the above configuration, it is possible to prevent the curtain airbag from flying out of the vehicle while suppressing both an increase in the cost required for the curtain airbag device and a restriction on visibility.

[0010] In this case, the bar-shaped member may be disposed adjacent to the window glass with a gap therebetween that is smaller than the thickness of the curtain airbag when fully inflated.

[0011] By making the bar-shaped members separate from the window glass, the structure of the window can be simplified. Also, by making the gap between the bar-shaped members and the window glass smaller than the thickness of a fully inflated curtain airbag, it is possible to prevent the curtain airbag from getting into the gap between the window glass and the bar-shaped members.

[0012] The bar-shaped member may be a division bar that is disposed inside the window opening and divides the window glass.

[0013] With this configuration, the curtain airbag can be reliably prevented from entering the gap between the bar-shaped member and the window glass.

[0014] Furthermore, the vehicle may further include a seat arranged adjacent to a side wall of the vehicle for an occupant to sit on, and the bar-shaped member may be arranged at a height below the head of the occupant sitting on the seat.

[0015] With this configuration, the head of the occupant can be reliably protected by the curtain airbag.

[0016] The vertical position of the lower edge of the window opening may be substantially the same as the vertical position of the lower edge of the fully inflated curtain airbag, or may be lower than the vertical position of the lower edge.

[0017] With this configuration, it is possible to reduce the cost required for the curtain airbag device while ensuring a large window opening.

[0018] Furthermore, the vehicle may include a side mirror positioned outward in the vehicle width direction from the window, and the bar-shaped member may pass below a straight line connecting the lowest end of the 95% iris and the lower end of the side mirror.

[0019] With this configuration, the bar-shaped member does not obstruct the driver's field of vision. [Effects of the Invention]

[0020] The vehicle side structure disclosed in this specification can prevent the curtain airbag from jumping out of the vehicle while suppressing both an increase in cost and a restriction on visibility. [Brief explanation of the drawings]

[0022] The vehicle side structure will be described below with reference to the drawings. Fig. 1 is a view of the vehicle side (the right side in the illustrated example) as seen from inside the vehicle. Fig. 2 is a view of the vehicle side when the curtain airbag 22 is deployed. Fig. 3 is a view of the vehicle side from the AA position in Fig. 2. expansion In the following figures, "Fr," "Up," and "Rh" indicate the front, top, and right sides of the vehicle, respectively.

[0023] As shown in Figures 1 to 3, a window 11 is provided in a side wall 10 of a vehicle. The window 11 is composed of a window opening 12 and window glass 14 that fits into the window opening 12. A trim 18, which is a resin design panel, is arranged below the window opening 12. The window 11 in this example is a fixed window in which the window glass 14 is fixed so as not to move relative to the window opening 12. However, it goes without saying that the window 11 may also be an opening / closing window in which the window glass 14 can be raised and lowered relative to the window opening 12.

[0024] A seat 40 (not shown in FIG. 2) in which an occupant 100 sits is arranged to the side of the window 11. In this example, the window 11 is arranged in the front part of the vehicle, and the seat 40 arranged to the side of the window 11 is the driver's seat or the passenger seat. As shown in FIGS. 1 and 3, the lower edge of the window opening 12 is located below the head 100a of the occupant 100 sitting in the seat 40, and the upper edge of the window opening 12 is located sufficiently above the head 100a of the occupant 100.

[0025] A curtain airbag device 20 is provided above the window 11. The curtain airbag device 20 is a device that, when a strong impact is received from the side of the vehicle, inflates and deploys a curtain airbag 22 between the sidewall 10 and the occupant 100, thereby absorbing an impact on the head 100a of the occupant 100. The curtain airbag device 20 includes a curtain airbag 22 and an inflator 24. The curtain airbag 22 is a bag-shaped member. Under normal conditions, as shown in FIG. 7 , the curtain airbag 22 is wound up in an outer roll and assembled as a member that is long in the longitudinal direction of the vehicle. The curtain airbag 22 is fixed with an adhesive or restrained with a restraining member to maintain the rolled shape. The adhesive strength of the adhesive or the restraining force of the restraining member are both sufficiently smaller than the inflation pressure of the curtain airbag 22 that is generated when the inflator 24, which will be described later, is activated. Therefore, when the inflator 24 is activated, the curtain airbag 22 deploys against the adhesive force of the adhesive or the restraining force of the restraining member.

[0026] As shown in Figs. 2 and 3, the fully inflated curtain airbag 22 covers most of the window 11. The fully inflated curtain airbag 22 has an inflatable portion 22a that inflates when gas flows through it, and a non-inflatable portion 22b that does not allow gas to flow through it. In Fig. 2, the non-inflatable portion 22b is hatched. By partially providing the non-inflatable portion 22b that does not inflate in the curtain airbag 22 in this way, the amount of gas required for full inflation can be reduced, and the curtain airbag 22 can be deployed more quickly. The location of the inflatable portion 22a is determined taking into consideration the position of the occupant 100.

[0027] The dimension Lb (see FIG. 2) of the inflation portion 22a in the vehicle's front-rear direction is approximately the same as the dimension Lw (see FIG. 1) of the window 11 in the front-rear direction. In addition, the lower edge of the inflation portion 22a of the curtain airbag 22 is located above the lower edge of the window 11 and below the bar-shaped member 30, which will be described later. By positioning the lower edge of the inflation portion 22a above the lower edge of the window 11, the size of the curtain airbag 22 can be reduced, and the cost required for the curtain airbag device 20 can be reduced.

[0028] When the inflator 24 detects a collision, it generates gas to inflate the curtain airbag 22. In this example, two inflators 24 are provided spaced apart in the longitudinal direction of the vehicle, and gas is supplied to the curtain airbag 22 from two locations.

[0029] As shown in FIGS. 1 to 3, a transverse pipe 32 functioning as a bar-shaped member 30 is provided on the inner side of the window 11 in the vehicle width direction. The transverse pipe 32 is a pipe that extends in the longitudinal direction of the vehicle so as to divide the window opening 12 into upper and lower sections when viewed from the side of the vehicle. The transverse pipe 32 is made of a high-strength material such as metal. Both ends of the transverse pipe 32 are fixed to the side wall 10 of the vehicle via fixing brackets 36 (see FIGS. 1 and 2).

[0030] As shown in Fig. 3 , when the curtain airbag 22 is fully inflated, the transverse pipe 32 is located between the curtain airbag 22 and the window glass 14. In other words, the transverse pipe 32 is located outward in the vehicle width direction from the fully inflated curtain airbag 22 and inward in the vehicle width direction from the window glass 14. Furthermore, the gap Wa between the transverse pipe 32 and the window glass 14 is smaller than the thickness Wb of the curtain airbag 22. Therefore, the curtain airbag 22 does not get between the transverse pipe 32 and the window glass 14, and is inflated and deployed more inward in the vehicle width direction from the transverse pipe 32.

[0031] The cross pipe 32 is disposed above the lower edge of the window opening 12 and below the head 100a of the occupant 100. The position of the head 100a of the occupant 100 varies greatly depending on the occupant's physique, etc. Therefore, the position of the head 100a of the occupant 100 may be estimated, for example, based on the iris. The iris is an ellipse that encompasses the eye positions of various drivers. Such an iris is calculated by statistically analyzing the driver's eye positions. The range of the iris is specified, for example, in the Japanese Industrial Standards as "JIS D0021: Automobile Driver Eye Range." The ellipse that includes P% of the driver's eye distribution is called the "P% iris." If the length from the center of the pupil to the tip of the chin is α, the lower end of the head 100a of the occupant 100 can be estimated, for example, by the length α below the lowest end of the 95% iris. The length α from the center of the pupil to the tip of the chin can also be determined statistically. The transverse pipe 32 is disposed below the lower end of the head 100a determined in this manner.

[0032] The cross pipe 32 is provided at a position that does not obstruct the driving field of the occupant 100, particularly the driver. For example, as shown in Fig. 3, the cross pipe 32 is provided at a position that passes below the line K1 that connects the lower end of the driver's 95% iris 50 and the lower end of the side mirror 16. By providing such a position, the driver's driving field of view can be appropriately ensured even with the cross pipe 32 provided.

[0033] Next, the reason for providing such a cross pipe 32 will be explained in comparison with a comparative example. Fig. 5 is a cross-sectional view showing the side structure of the comparative example. As shown in Fig. 5, the comparative example does not have a bar-shaped member 30.

[0034] The behavior of a vehicle during a side collision in which an obstacle collides with the side of the vehicle will be described. When a side collision is detected, the curtain airbag device 20 activates the inflator 24 to inflate and deploy the curtain airbag 22. Furthermore, the head 100a of the occupant 100 moves outward in the vehicle width direction due to inertial force. At this time, the curtain airbag 22 is interposed between the window glass 14 and the head 100a of the occupant 100, so that the head 100a quickly hits the curtain airbag 22 and further movement is restricted. As a result, the head 100a of the occupant 100 is appropriately protected.

[0035] However, depending on the type of side collision, the impact of the collision may cause the window glass 14 to break and shatter. That is, a side collision may result in the member (i.e., the window glass 14) that restricts the movement of the curtain airbag 22 being no longer present inside the window opening 12. Also, if the window 11 is an opening / closing window, the window 11 may be open before the side collision. In such a case, if there were no bar-shaped member 30, as in the comparative example, the curtain airbag 22 would be pushed by the head 100a and may fly outward in the vehicle width direction.

[0036] In order to prevent the curtain airbag 22 from projecting out, it is possible to extend the lower edge of the inflation portion 22a below the lower edge of the window opening 12. With this configuration, the lower part of the inflation portion 22a gets caught on the trim 18 provided below the window opening 12, thereby preventing the curtain airbag 22 from projecting out. However, in this case, the size of the curtain airbag 22 must be increased, which increases the cost required for the curtain airbag device 20. Therefore, it is also possible to raise the lower edge of the window opening 12 upward rather than increasing the size of the curtain airbag 22. However, raising the lower edge of the window opening 12 upward and increasing the area of ​​the trim 18 causes another problem in that the field of view of the occupant 100, particularly the driver, is correspondingly narrowed.

[0037] In this example, to prevent the curtain airbag 22 from projecting out, a bar-shaped member 30 (specifically, a cross pipe 32) is provided that divides the window opening 12 into upper and lower parts in a side view. When such a cross pipe 32 is provided, even if the curtain airbag 22 is pressed outward in the vehicle width direction by the head 100a, as shown in FIG. 4 , the lower part of the inflation portion 22a is caught on the cross pipe 32, thereby effectively preventing the curtain airbag 22 from projecting out. As a result, the head 100a of the occupant 100 can be more appropriately protected. Meanwhile, in this example, the window opening 12 extends downward beyond the cross pipe 32, thereby maintaining a wide field of view. Furthermore, in this example, the lower edge of the inflation portion 22a is positioned above the lower edge of the window opening 12, thereby preventing the curtain airbag 22 from becoming larger and preventing an increase in costs required for the curtain airbag device 20. That is, according to this example, it is possible to effectively prevent the curtain airbag 22 from flying out of the vehicle while preventing both an increase in cost and a restriction on visibility.

[0038] When a portion of the curtain airbag 22 above the cross pipe 32 is pressed outward in the vehicle width direction, the curtain airbag 22 bends so as to convex outward in the vehicle width direction. As a result of this bending, the lower edge of the inflatable portion 22a slides upward. In this example, the size of the inflatable portion 22a is set so that, even when this upward slide occurs, the lower edge of the inflatable portion 22a remains below the cross pipe 32. For example, assuming that the vertical distance from the vertical center of the bar-shaped member 30 to the lower edge of the inflatable portion 22a is Ha (see FIG. 3 ) and the thickness of the inflatable portion 22a (i.e., the dimension in the vehicle width direction) is Wb, the distance Ha may be greater than 0.5×Wb, for example, Ha > 0.8×Wb, or Ha > Wb.

[0039] Furthermore, in order to prevent the curtain airbag 22 from jumping out of the vehicle, it is sufficient to maximize the overlapping range in the vehicle longitudinal direction between the curtain airbag 22 and the transverse pipe 32. Therefore, in this example, as shown in Fig. 2, the vehicle longitudinal direction dimension Lb of the inflatable portion 22a at the installation height H1 of the transverse pipe 32 is made approximately the same as the vehicle longitudinal direction dimension Lw of the window opening 12. As a result, the curtain airbag 22 is caught on the transverse pipe 32 over a wide range, which effectively prevents the curtain airbag 22 from jumping out of the vehicle.

[0040] Furthermore, the diameter of the transverse pipe 32 is preferably as small as possible as long as the required rigidity can be maintained. This is because the smaller the diameter of the transverse pipe 32, the less it obstructs visibility. Furthermore, the smaller the diameter of the transverse pipe 32, the more easily the transverse pipe 32 bites into the curtain airbag 22, preventing the curtain airbag 22 from sliding up. That is, as shown in FIG. 6 , the contact area with the curtain airbag 22 is larger in the case of a large-diameter transverse pipe 32 (the case in the upper part of FIG. 6 ) than in the case of a small-diameter transverse pipe 32 (the case in the lower part of FIG. 6 ). Therefore, in the case of a large-diameter transverse pipe 32, stress concentration on the curtain airbag 22 is gentler than in the case of a small-diameter transverse pipe 32, and the transverse pipe 32 bites into the curtain airbag 22 more gently. In addition, in the case of a large-diameter transverse pipe 32, the bite is gentler, so the curtain airbag 22 is more likely to slide along the surface of the transverse pipe 32 and slide up. On the other hand, in the case of a small-diameter transverse pipe 32, the transverse pipe 32 bites sharply into the curtain airbag 22, causing the surface of the curtain airbag 22 to bend sharply, making it difficult for the curtain airbag 22 to slide upward. As a result, the curtain airbag 22 can be effectively prevented from being thrown out of the vehicle. Therefore, the transverse pipe 32 is made as small as possible while still maintaining its strength. Although it depends on the material, for example, the vertical dimension of the transverse pipe 32 may be ½ or less, more specifically ⅕ or less, of the thickness Wb of the inflatable portion 22a.

[0041] Furthermore, in order to prevent the curtain airbag 22 from sliding up, a high-friction portion 38 with a high friction coefficient may be provided on the surface of the transverse pipe 32, as shown in the enlarged view at the bottom of Fig. 6. The high-friction portion 38 may be provided in a range of the surface of the transverse pipe 32 that does not come into contact with the curtain airbag 22 during the deployment process of the curtain airbag 22 but that comes into contact with the curtain airbag 22 when the curtain airbag 22 is pressed outward (i.e., the range shown by the thick line in Fig. 6), so as not to hinder smooth deployment of the curtain airbag 22. An example of such a position is near the top of the transverse pipe 32. The high-friction portion 38 may be formed by attaching or applying a material with a high friction coefficient, such as rubber, to the surface of the transverse pipe 32, or may be formed by subjecting the surface of the transverse pipe 32 to processing that forms a plurality of irregularities, such as knurling.

[0042] In any case, the side structure of this example can effectively prevent the curtain airbag 22 from flying out of the vehicle while preventing both an increase in cost and a restriction of visibility. The configuration described above is one example, and other configurations may be changed as appropriate as long as the bar-shaped member 30 that divides the window opening 12 into upper and lower sections is provided inside the window opening 12 or on the inner side of the window opening 12 in the vehicle width direction and on the outer side of the fully inflated curtain airbag 22 in the vehicle width direction, and at least a portion of the fully inflated curtain airbag 22 extends below the bar-shaped member 30.

[0043] For example, in the above example, the bar-shaped member 30 is a cross pipe 32 that is a member completely separated from the window glass 14. This configuration simplifies the configuration of the window 11. However, the form of the bar-shaped member 30 may be changed as appropriate. Therefore, as shown in FIG. 7 , the bar-shaped member 30 may be a division bar 34 that is arranged inside the window opening 12 and divides the window glass 14 into upper and lower parts. This configuration reliably prevents the curtain airbag 22 from entering the gap between the bar-shaped member 30 and the window glass 14.

[0044] The bar-shaped member 30 may also be inclined with respect to the longitudinal axis of the vehicle. For example, as shown in FIG. 8 , the bar-shaped member 30 may be inclined so as to become upward as it moves toward the rear of the vehicle. In other words, the bar-shaped member 30 may be inclined so as to become downward as it approaches the side mirror 16. With this configuration, the bar-shaped member 30 is more likely to pass below the line connecting the eyes of the occupant 100 and the side mirror 16, thereby effectively preventing the bar-shaped member 30 from obstructing the driver's field of vision. On the other hand, when the bar-shaped member 30 is inclined upward toward the rear, the rear portion of the bar-shaped member 30 is located relatively higher, so that the area of ​​the portion of the inflation portion 22a that extends below the bar-shaped member 30 can be increased. This more reliably prevents the curtain airbag 22 from being thrown out of the vehicle. Furthermore, the bar-shaped member 30 may be positioned above the straight line K1 connecting the bottom end of the 95% iris 50 and the bottom corner of the side mirror 16, as long as it is small enough and does not obstruct the driver's field of view.
