Description

  The present invention relates to a mounting structure for a vehicle pad member, and more particularly, to a vehicle pad member that is fixed to a side rail of a vehicle and has both a function of absorbing head collision energy and a function of guiding airbag inflation. It relates to the mounting structure.

  In vehicles such as automobiles, it is known to provide a pad member that absorbs energy at the time of collision between a vehicle body panel and an interior panel (for example, a center pillar trim). Further, in a vehicle provided with an airbag device (curtain airbag) above the vehicle side window, it is known to provide a guide member for guiding the inflation of the airbag.

  For example, Patent Document 1 discloses a metal plate forming member that deforms and absorbs collision energy when the head collides, and guides the airbag when the airbag is inflated. The metal plate forming member has an inclined surface such as a launch ramp extending obliquely downward toward the vehicle interior, and guides an airbag inflated by a collision to the vehicle interior. This metal plate forming member is welded to the roof frame area (side rail) of the vehicle body.

  Patent Document 2 discloses forming a guide portion for inflating and deploying a curtain airbag in a predetermined direction on a corner gazette that connects a roof rail reinforcement and a roof side rail to increase strength. . The guide portion extends from below the corner gusset and forms an inclined surface toward the vehicle interior side. The corner gusset having the guide portion is fixed to a roof reinforcement and a roof side rail which are a part of the vehicle body by bolts.

  In general, it is known to use a synthetic resin clip as a mounting structure for an interior panel of a vehicle. For example, Patent Document 3 discloses a structure in which a harness protector is attached to a vehicle body panel using a flexible clip formed with a hook-shaped or shade-shaped panel locking portion that is inserted into a mounting hole of a vehicle panel. Is disclosed. In the mounting structure described in the document, a clip holder is provided on a harness protector, and the clip is slid into the clip holder. In addition, the base wall of a clip holder and the seat part of a clip are formed with the latching | locking part for clip detachment prevention.

  Patent Document 4 discloses a structure in which a door trim is attached to an inner panel of a door body using a synthetic resin clip and a pedestal. A support slit whose one end is open is formed in the pedestal, and the neck of the clip is inserted into the support slit. Further, an insertion resistance portion having a width narrower than the neck portion of the clip is formed in the support slit, and a claw portion that engages with the flange portion of the clip is formed in the insertion opening to prevent the clip from falling off.

JP 2000-255367 A (page 3, FIG. 2) Japanese Unexamined Patent Publication No. 2009-56873 (page 5-6, FIG. 3) JP 2003-343526 A (page 3-5, FIG. 1) JP 2003-314516 A (page 3-5, FIG. 4)

  However, the above-described prior art has room for improvement from the viewpoint of achieving both energy absorption performance during collision deformation and guide performance during airbag inflation and improving assembly workability.

  Specifically, since welding and bolt fastening can firmly fix the pad member and the vehicle body, they are preferable from the viewpoint of withstanding the pressing force of the airbag and appropriately guiding the airbag. On the other hand, since the pad member and the vehicle body are strongly coupled, the deformation of the pad member is limited, and the energy absorption performance of the pad member tends to decrease. Therefore, it is necessary to secure a sufficient amount of deformation and collision energy absorption at a portion other than the joint portion of the pad member with the vehicle body.

  Moreover, since it is necessary to secure a work space in consideration of a welding tool, a fastening tool, etc. for welding and bolt fastening, it is difficult to adopt in the case of a shape in which the work space cannot be secured. In the case of welding, the material of the pad member is also limited.

  On the other hand, in the structure in which the pad member is attached using a resin clip or the like, the clip portion cannot withstand the inflating load of the airbag, and the clip may be broken or detached. If the clip joining of the pad member is released, the function of guiding the airbag inflating in an appropriate direction is impaired.

  Further, by adopting a so-called two-piece clip that expands and fixes the grommet by inserting a pin or the like into the grommet made of synthetic resin, the strength of the joint can be increased. However, when the joint strength of the clip is increased to increase the load resistance when the airbag is inflated, the deformation of the pad member is restricted and the energy absorption performance is reduced, as in the case of using the above-described welding and bolts. There is a point.

  Further, when the two-piece clip is adopted, the number of parts increases, and there is a problem that the number of steps for attaching the clip increases. For this reason, the efficiency of the assembly work is reduced.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle pad member mounting structure that can achieve both a collision energy absorption performance and an airbag guide function and is excellent in assembling workability. And

The mounting structure for a vehicle pad member according to the present invention is a structure for mounting a vehicle pad member having a guide portion for guiding the inflation of an airbag from below to a side rail of a vehicle using a clip. The pad member includes a flange portion extending upward along the side rail from an end portion on the side rail side of the guide portion, a mounting hole formed in the flange portion and mounted with the clip, An opening that connects to the mounting hole and opens the mounting hole downward, and the clip passes through the opening and is mounted on the mounting hole from below the flange portion to be formed on the side rail. a grommet which is inserted into the mounting holes, are inserted into the pin hole of the grommet and expanded the grommet have a, a pin engaging into the mounting hole, the grommet includes a seat, front And a locking portion that is erected from one main surface of the seat portion and is inserted into the mounting hole and the mounting hole, and the seat portion has the first grommet in a state where the grommet is mounted in the mounting hole. A main surface is in contact with a surface on the vehicle inner side of the flange portion, and the vehicle pad member is connected to the insertion resistance portion formed in the opening portion and having an opening width smaller than an outer diameter of the locking portion, and the opening portion. characterized in that it have a, a seat insertion portion for inserting into the interior side of the flange portion from below the flange portion of the seat.

  According to the mounting structure of the vehicle pad member of the present invention, it has an opening that leads to the mounting hole for mounting the clip and opens the mounting hole downward. Thereby, it is permitted that the clip passes through the opening and the flange moves upward at the time of a head collision, and a large amount of deformation and energy absorption of the vehicle pad member can be ensured.

  Further, when the airbag is inflated, the clip does not pass through the opening portion, and supports the flange portion to suppress the movement of the flange portion. Thereby, the guide part of the pad member for vehicles can guide the air bag which expands suitably.

  Moreover, the said clip has a grommet and the pin which expands this grommet and engages with the attachment hole of a side rail. Thereby, the coupling | bonding force by a clip can be improved and the load resistance at the time of airbag expansion | swelling can be improved.

  Further, an insertion resistance portion having an opening width smaller than the outer diameter of the locking portion of the grommet is formed in the opening portion. Thereby, it is possible to prevent the clip temporarily mounted in the mounting hole from dropping off, and to improve the efficiency of the assembly work.

  Further, the vehicle pad member has an abutting portion that abuts on the grommet mounted in the mounting hole from the vehicle inner side. As a result, it is possible to prevent the clip temporarily mounted in the mounting hole from being tilted or falling out to the inside of the vehicle, and the workability is further improved.

  Further, a locking projection may be formed on the end face of the seat portion of the grommet, a locking receiving portion may be formed on the flange portion, and the locking projection may be supported by a contact portion of the locking receiving portion. As a result, the function of supporting the temporarily mounted clip can be further enhanced.

  Alternatively, the clip-attached vehicle pad member may be attached to the side rail after the clip with the pin temporarily inserted into the grommet is temporarily attached to the attachment hole. Thereby, the operation | work which attaches the pad member for vehicles becomes easy, and productivity improves.

  Furthermore, you may provide the pressing member which contact | abuts to the said guide part and supports this guide part from the downward direction. Thereby, the load resistance at the time of airbag expansion | swelling can further be improved, and the function which guides an airbag can be maintained suitably.

  The pressing member may be configured to be separable from the guide portion. Thereby, the said pressing member can further improve energy absorption performance, without inhibiting that the guide part and flange part of a vehicle pad member deform | transform upwards at the time of a head collision.

  Hereinafter, an attachment structure of a side rail pad 10 (vehicle pad member) according to an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing the interior of a vehicle 1 provided with a side rail pad 10. FIG. 1 shows a state in which the right side of the passenger compartment is viewed obliquely from the upper front side. In FIG. It is.

  The side rail pad 10 is provided above the center pillar 7 located beside the seat 9 and below the airbag 5 as indicated by a chain line circle X in FIG. The side rail pad 10 is made of, for example, an injection-molded synthetic resin, and is fixed to the side rail 2, and has both a function of absorbing head collision energy and a function of guiding the inflation of the airbag 5.

  FIG. 2 is an exploded perspective view showing the attachment structure of the side rail pad 10, and shows an enlarged view around the chain line circle X in FIG. 1. As shown in FIG. 2, the side rails 2 extend in the front-rear direction of the vehicle 1 and are provided on the left and right sides of the roof panel 6 as a pair (appears only on the right side in FIG. 2).

  As described above, the side rail pad 10 is disposed on the side of the vehicle interior of the side rail 2. Specifically, the side rail pad 10 is fixed to the attachment hole 3 formed in the side rail 2 using the clip 30.

  In addition, an interior panel (a roof side trim, a center pillar trim, etc.) (not shown) is attached to the side of the vehicle interior of the side rail pad 10.

  FIG. 3 is a perspective view of the upper part of the side rail pad 10 provided on the right side of the vehicle 1 as viewed obliquely from the front in the vehicle. In FIG. 3, the diagonally lower left direction on the page is the front side of the vehicle, and the diagonally lower right side of the page is the vehicle interior direction (in the vehicle width direction).

  As shown in FIG. 3, the side rail pad 10 has an upper portion projecting from the inside of the vehicle, and an upper surface of the side rail pad 10 guides the inflating airbag 5 (see FIG. 1) toward the interior of the vehicle. 11 is constituted.

  A flange portion 12 for attaching the side rail pad 10 to the side rail 2 (see FIG. 2) extends upward from an end portion on the vehicle exterior side of the guide portion 11. The flange portion 12 is formed with a mounting hole 14 that passes through the flange portion 12 in the vehicle width direction. The side rail pad 10 is fixed to the side rail 2 by a clip 30 (see FIG. 4) inserted into the mounting hole 14.

  The clip 30 may be fixed at one place (mounting hole 14 or the like), but in this embodiment, two fixed places are provided. Thus, by fixing a plurality of places, the load by the airbag 5 (see FIG. 1) can be distributed and received at the plurality of fixed places. Further, the side rail pad 10 can be prevented from rotating.

  Hereinafter, the mounting structure of the side rail pad 10 will be described in detail by taking one fixed portion indicated by a chain line circle Y in FIG. 3 as an example. In addition, when fixing several places, the same fixing method can be employ | adopted about each fixing location.

  4 is a cross-sectional view showing the attachment structure of the side rail pad 10, which corresponds to the cross section taken along the line ZZ in FIG. 3 and shows a vertical cross section including the central axis of the mounting hole 14. In FIG. 4, the right side of the drawing is the vehicle interior direction, and the left side of the drawing is the direction outside the vehicle.

  As shown in FIG. 4, the side rail pad 10 is disposed below the airbag 5 and has a guide portion 11 that guides the inflation of the airbag 5. A guide surface 11a that is an upper surface of the guide portion 11 is inclined obliquely downward toward the vehicle interior side. The flange portion 12 erected so as to be bent from the vehicle outer end portion of the guide portion 11 extends upward along the side rail 2.

  As described above, the mounting hole 14 is formed in the flange portion 12. A clip 30 including a grommet 31 and a pin 32 is inserted into the mounting hole 14. Further, the clip 30 mounted in the mounting hole 14 is also inserted into the mounting hole 3 formed in the side rail 2. Thus, the side rail pad 10 and the side rail 2 are fixed by the clip 30.

  FIG. 5 is an exploded perspective view showing the attachment structure of the side rail pad 10, and corresponds to an enlarged view near the chain line circle Y shown in FIG.

  As shown in FIG. 5, the grommet 31 of the clip 30 includes a substantially rectangular flat plate-like seat portion 34, and a locking portion 33 erected from one main surface 34 a (the back surface that does not appear on the paper surface) of the seat portion 34, Have

  The seat portion 34 is a portion that presses the flange portion 12 from the vehicle inner side when the side rail pad 10 is fixed by the clip 30. One main surface 34 a of the seat portion 34 abuts on the vehicle inner surface of the flange portion 12 in a state where the grommet 31 is mounted in the mounting hole 14. Specifically, one main surface 34 a of the seat portion 34 abuts on the grommet mounting surface 13.

  The locking portion 33 is a portion that is inserted into the mounting hole 14 of the side rail pad 10 and the mounting hole 3 (see FIG. 2) of the side rail 2 (see FIG. 2) and fixes both. In the vicinity of the central axis of the locking portion 33, a pin hole 37 penetrating the locking portion 33 and the seat portion 34 is formed along the central axis.

  The inner diameter of the pin hole 37 is slightly smaller than the outer diameter of the pin 32. Accordingly, by inserting the pin 32 into the pin hole 37, the locking portion 33 expands in the radial direction, and the locking portion 33 can be engaged with the mounting hole 14 and the mounting hole 3. The pin 32 is configured to be inserted from the other main surface 34b side opposite to the one main surface 34a of the seat portion 34.

  Here, a slit 35 extending in the axial direction may be formed in the locking portion 33 so that the distal end side of the locking portion 33 can be divided. Thereby, the expansion of the locking portion 33 when the pin 32 is inserted is increased, and the support force by the clip 30 can be increased. Moreover, you may form the protrusion (for example, shade-shaped hook etc.) for raising an engaging force in the side surface of the latching | locking part 33. FIG.

  A grommet mounting surface 13 is formed on the inner side of the flange portion 12 formed on the side rail pad 10. A mounting hole 14 penetrating in the vehicle width direction is formed in the grommet mounting surface 13 of the flange portion 12.

  The mounting hole 14 opens downward, that is, in a direction opposite to the airbag 5 (see FIG. 4). Specifically, an opening 15 that is an opening connected to the mounting hole 14 is formed in the lower portion of the mounting hole 14. Thus, the locking portion 33 of the grommet 31 can be mounted in the mounting hole 14 from below the flange portion 12 through the opening 15.

  The opening 15 is formed with an insertion resistance portion 16 having an opening width slightly smaller than the outer diameter of the locking portion 33 of the grommet 31. Thereby, in the operation | work which attaches the side rail pad 10, the fall of the clip 30 temporarily mounted | worn in the mounting hole 14 can be prevented.

  That is, when the clip 30 is mounted in the mounting hole 14, by pushing the clip 30, the locking portion 33 and the insertion resistance portion 16 are elastically deformed, and passage of the locking portion 33 is allowed. On the other hand, after the clip 30 is attached, the insertion resistance portion 16 prevents the passage of the locking portion 33, so that the clip 30 can be prevented from dropping downward.

  Further, a seat portion insertion portion 17 that extends to the inside of the vehicle is formed near the lower end of the flange portion 12 (near the vehicle outer end portion of the guide portion 11). The seat portion insertion portion 17 is an opening that penetrates in the vertical direction and allows the seat portion 34 to be inserted from below the flange portion 12 to the vehicle interior side of the flange portion 12.

  In addition, a pin insertion portion 18 is formed on the vehicle inner side of the seat portion insertion portion 17. The pin insertion portion 18 is an opening connected to the seat portion insertion portion 17 and further widened on the vehicle inner side. The pin insertion portion 18 is an opening through which the pin 32 temporarily inserted into the grommet 31 is passed.

  Here, in a state where the grommet 31 is mounted in the mounting hole 14, at least a portion of the main surface 34 b (the other main surface 34 b) on the vehicle interior side of the seat portion 34 is at least a portion of the peripheral surface constituting the seat portion insertion portion 17. Abut. Specifically, a contact portion 17a indicated by hatching is formed on the inner peripheral surface of the seat portion insertion portion 17, and the contact portion 17a is hatched on both sides near the lower end of the main surface 34b of the seat portion 34. It abuts on the abutting portion 34c shown.

  As a result, the abutting portion 17a of the seat portion insertion portion 17 supports the abutting portion 34c on the vehicle interior side of the seat portion 34. Therefore, in the work of attaching the side rail pad 10, the clip 30 temporarily attached to the attachment hole 14 is attached to the vehicle interior side. Can be prevented from falling off.

  A claw-shaped locking projection 40 is formed on the upper end surface of the seat portion 34. The locking projection 40 is inserted into the locking receiving portion 20 formed on the flange portion 12 above the mounting hole 14.

  FIG. 6 is a perspective view for explaining the latch receiving portion 20 and shows a state in which the vicinity of the mounting hole 14 is viewed obliquely from below. In FIG. 6, the upward direction on the paper is the vehicle interior, and the diagonally lower right side of the paper is the downward direction.

  As shown in FIG. 6, the latch receiving portion 20 is a recess or a through hole that opens downward and is formed in the upper peripheral wall 19 of the recess that forms the grommet mounting surface 13 of the flange portion 12. An abutting portion 20 a is formed on the inner side of the peripheral surface constituting the locking receiving portion 20.

  Referring again to FIG. 5, when the grommet 31 is mounted in the mounting hole 14, the locking protrusion 40 formed on the seat portion 34 is fitted into the locking receiving portion 20 formed on the flange portion 12. The Then, at least a part of the contact surface 40 a on the vehicle interior side of the locking projection 40 contacts the contact portion 20 a formed on the locking receiving portion 20.

  As a result, the abutting portion 20a of the latch receiving portion 20 supports the abutting surface 40a on the inner side of the latching protrusion 40, so that the clip 30 temporarily mounted in the mounting hole 14 is attached to the vehicle in the operation of attaching the side rail pad 10. It can be prevented from falling off inside.

  Furthermore, by combining the support of the locking projection 40 by the contact portion 20a of the lock receiving portion 20 and the support of the contact portion 34c by the contact portion 17a of the seat insertion portion 17 described above, the clip 30 is combined. The inclination of can be suppressed. Thereby, the efficiency of the operation | work which inserts the latching | locking part 33 of the clip 30 in the attachment hole 3 (refer FIG. 2) of the side rail 2 (refer FIG. 2) can be improved.

  Instead of or in addition to the contact portions 17a and 20a, a contact portion that contacts the other part of the grommet 31 from the vehicle inner side may be formed on the side rail pad 10. Moreover, you may form the contact location 34c contact | abutted to the contact part 17a in convex shape. This facilitates the operation of inserting the clip 30 into the mounting hole 14 and increases the pressing force by the contact portion 17a.

  Next, with reference to FIG. 7 and FIGS. 4 to 5, a process of attaching the side rail pad 10 will be described. FIG. 7 is a cross-sectional view for explaining a part of the attaching process, and shows the same cross section as FIG.

  First, as shown by an arrow A in FIG. 5, the pin 32 is temporarily inserted into the pin hole 37 of the grommet 31, and the clip 30 is temporarily assembled. Here, the pin 32 is not inserted to the innermost end, and the locking portion 33 is not expanded in diameter.

  Next, as indicated by an arrow B, the temporarily assembled clip 30 is temporarily attached to the attachment hole 14 from below the flange portion 12. Specifically, the locking portion 33 of the grommet 31 passes through the opening 15, the seat portion 34 passes through the seat portion insertion portion 17, and the temporarily inserted pin 32 passes through the pin insertion portion 18. .

  Here, since the width of the insertion resistance portion 16 formed in the opening portion 15 is slightly smaller than the outer diameter of the locking portion 33, the temporarily attached clip 30 does not fall down. Further, the main surface 34b (contact portion 34c) on the vehicle interior side of the seat portion 34 abuts on the contact portion 17a of the seat portion insertion portion 17, and the contact surface 40a on the vehicle interior side of the lock projection 40 is a lock receiving portion. Since it abuts against the abutment portion 20a of the 20, the temporarily attached clip 30 does not fall off also to the inside of the vehicle.

  Next, as shown by an arrow C in FIG. 7, the side rail pad 10 with the clip 30 temporarily attached is attached to the side rail 2. Specifically, the locking portion 33 of the grommet 31 is inserted into the mounting hole 3 of the side rail 2.

  Here, as described above, the temporarily mounted clip 30 is supported by the contact portion 17a and the contact portion 20a, and thus does not fall off to the vehicle inner side (broken line arrow C2). In addition, the inclination and displacement of the clip 30 are suppressed, and the insertion work can be easily performed.

  Finally, as indicated by the arrow D, the temporarily inserted pin 32 is pushed in as far as possible. As a result, as shown in FIG. 4, the locking portion 33 of the grommet 31 is expanded in the radial direction, and the locking portion 33 is engaged and fixed to the mounting hole 3 and the mounting hole 14. As a result, the side rail pad 10 is fixed to the side rail 2.

  As described above, in the present embodiment, the clip 30 is temporarily attached to the side rail pad 10 in advance, and the side rail pad 10 is efficiently attached to the side rail pad while preventing the temporarily attached clip 30 from falling off or shifting. 2 can be attached.

  Next, absorption of collision energy by the side rail pad 10 will be described in detail with reference to FIG. FIG. 8 is a cross-sectional view for explaining the absorption of collision energy, and shows the same cross section as FIG. In FIG. 8, the deformed side rail pad 10 at the time of collision is indicated by a solid line, and the side rail pad 10x before the collision (before deformation) is indicated by a chain line.

  As shown by an arrow F in FIG. 8, for example, when an occupant's head collides from the indoor side and an impact load acts on the side rail pad 10, the side rail pad 10 is crushed in the vehicle width direction. Deforms and absorbs collision energy.

  In particular, the present embodiment is characterized in that the flange portion 12 is slidable upward as indicated by an arrow B1. That is, the mounting hole 14 in which the clip 30 is mounted is connected to the opening 15 and opens downward, so that it can be detached from the clip 30 and moved upward.

  That is, since the engagement between the grommet 31 of the clip 30 and the mounting hole 14 is released at the time of a collision, even if the clip 30 does not move while being inserted into the mounting hole 3 of the side rail 2, only the flange portion 12 is connected to the side rail. Move upward along 2.

  Here, as described above, the opening 15 is formed with the insertion resistance portion 16 for preventing the temporarily attached clip 30 from falling off. However, if an impact load at the time of collision acts, the clip 30 and the insertion resistance portion 16 are elastically deformed, and the grommet 31 of the clip 30 can pass through the insertion resistance portion 16.

  Thus, since the flange part 12 can slide upward at the time of an indoor collision, the deformation | transformation amount and energy absorption amount of the side rail pad 10 can be ensured large. Thereby, the side rail pad 10 demonstrates the outstanding collision energy absorption performance.

  Next, the guidance of the airbag 5 by the side rail pad 10 will be described in detail with reference to FIG. FIG. 9 is a cross-sectional view for explaining the guidance of the airbag 5 and represents the same cross section as FIG.

  When a collision sensor or the like (not shown) detects a collision of the vehicle 1, as shown by an arrow P in FIG. 9, the airbag 5 is inflated downward and deployed (the airbag 5x is the inflating process of the airbag 5). Represents the image).

  At this time, the airbag 5x that swells downward vigorously collides with the guide portion 11 of the side rail pad 10 and pushes the guide portion 11 downward. In other words, the guide part 11 receives the pressing load by the airbag 5x which expands.

  The load by the airbag 5x is transmitted to the flange portion 12 and acts to press the clip 30 downward (in the direction of the broken line arrow B2). Specifically, the upper surface of the mounting hole 14 is in strong contact with the upper surface of the grommet 31 and presses the grommet 31 downward.

  Here, since the opening 15 connected to the mounting hole 14 opens below the mounting hole 14, even if a load that pushes the clip 30 downward from the flange 12 acts as described above, the clip 30. Does not pass through the opening 15.

  That is, when the airbag 5 is inflated, the clip 30 does not pass through the opening 15 and come off the mounting hole 14 due to the load of the airbag 5x that swells, and the flange portion 12 of the side rail pad 10 Does not move in the direction of B2.

  Moreover, in this embodiment, since the clip 30 using the grommet 31 and the pin 32 is employ | adopted, a fastening margin can be ensured large compared with the clip integrally formed. Thereby, the clip 30 exhibits an excellent pulling strength. Further, by appropriately selecting the material of the pin 32, the bending strength of the clip 30 can be increased without deteriorating the mounting work performance of the clip 30.

  As described above, the mounting structure of this embodiment exhibits a high bonding strength that can withstand the bulging load of the airbag 5. Thereby, when the airbag 5 expand | swells, it can prevent that the side rail pad 10 remove | deviates from the side rail 2, and deform | transforms large. As a result, the bulging airbag 5x can be appropriately guided toward the passenger compartment by the guide surface 11a of the guide portion 11.

  Next, an example in which the embodiment is modified will be described in detail with reference to FIG. FIG. 10 is a cross-sectional view showing a modification of the embodiment of the present invention, and shows a cross section corresponding to the cross section of FIG. In addition, the same code | symbol is attached | subjected about the component which show | plays the same or similar operation | movement and effect as already demonstrated embodiment, and the description is abbreviate | omitted.

  In the present embodiment, a buffer member 25 is provided as a pressing member that supports the guide portion 11 from below. The buffer member 25 is a foamed member made of a synthetic resin material such as polypropylene, for example, and has a function of absorbing energy at the time of collision to soften the impact and supporting the guide portion 11 from below.

  The buffer member 25 is disposed such that its upper surface 26 can come into contact with a surface 11 b on the opposite side of the guide surface 11 a of the guide portion 11. Thereby, the buffer member 25 can receive the press load at the time of the airbag 5 inflating, and can support the guide part 11 from the downward direction.

  In this manner, by supporting the guide portion 11 from below with the buffer member 25, the load acting on the clip 30 can be reduced, and the clip 30 can be prevented from being broken or detached. Thereby, it is possible to prevent the flange portion 12 of the side rail pad 10 from dropping downward as indicated by the dashed arrow B2.

  Moreover, since the buffer member 25 supports the guide part 11 from below, the deformation of the guide surface 11a when the airbag 5 is inflated can be suppressed. Thus, by providing the buffer member 25, the load resistance when the airbag 5 is inflated can be further improved, and the guide function of the airbag 5 by the guide portion 11 can be suitably maintained.

  A space 29 is formed between the buffer member 25 and the side rail pad 10 on the vehicle interior side of the buffer member 25. That is, the upper surface 26 and the lower surface 27 of the buffer member 25 are in contact with the side rail pad 10, and the side surface 28 on the vehicle interior side is not in contact with the side rail pad 10, leaving a space 29. Thereby, the deformation | transformation of the side rail pad 10 is accept | permitted at the time of a head collision, and collision energy can be absorbed effectively.

  The buffer member 25 is provided so as to be separable from the guide portion 11. That is, the buffer member 25 is provided so that it can be easily peeled off without being bonded to the guide portion 11 or even when bonded. Further, only one of the upper surface 26 and the lower surface 27 of the buffer member 25 may be bonded to the side rail pad 10 and the other may be provided so as to be separable from the side rail pad 10.

  Thereby, in the case of a head collision, the side rail pad 10 can be deformed as described with reference to FIG. 8 without being disturbed by the buffer member 25. Specifically, the flange portion 12 and the guide portion 11 of the side rail pad 10 move away from the buffer member 25 and are deformed upward. Thereby, the collision energy absorption performance of the side rail pad 10 can be suitably maintained.

  Moreover, the buffer member 25 is crushed in the vehicle width direction at the time of a head collision, and exhibits a function of absorbing collision energy. Thereby, collision energy absorption performance can further be improved.

  The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
