Moreover, FIG. 2 is a side view showing an example of the configuration of the side door. Furthermore, FIG. 3 is a side view showing a state in which the trim member is removed in FIG. 2. In addition, FIG. 4 is a perspective view showing an example of the configuration of the pad member in this embodiment.

1 to 4, a side door 10 of a vehicle has an inner panel 11 and an outer panel 12, and a trim member 20 is provided on the inner surface of the inner panel 11 inside the vehicle. A space is formed between the inner panel 11 and the trim member 20, and a pad member 30 having a predetermined thickness is arranged within the space. Furthermore, a seat 50 that is slidable in the longitudinal direction of the vehicle is arranged on the inside of the side door 10 at a predetermined interval in the vehicle width direction.

As shown in FIG. 1, the seat 50 includes a seat cushion part 51 that forms a seat part, a seat frame part 52 that supports the seat cushion part 51, and a seat back part 53 that forms a backrest. Further, as shown in FIG. 5, which is a cross-sectional view taken along the line AA in FIG. 1, the seat 50 is provided with a grip portion 55 for a reclining lever 54 on the outer side of the vehicle. In this embodiment, the grip portion 55 of the reclining lever 54 is arranged on the vehicle outer side of the seat cushion portion 51 and/or the seat frame portion 52.

The reclining lever 54 is an operating lever for locking or unlocking the reclining mechanism that allows the inclination angle of the seatback 53 to be adjusted. A passenger seated in the seat 50 can adjust the inclination of the seatback 53 to a desired angle by grasping the grip 55 provided on the reclining lever 54 and rotating it toward the upper side of the vehicle to unlock the reclining mechanism. There is a gap between the trim member 20 of the side door 10 and the grip 55 of the reclining lever 54. When the seat 50 is slid in the fore-aft direction of the vehicle, the positions of the reclining lever 54 and the grip 55 also slide in the fore-aft direction of the vehicle.

Specifically, the side door 10 is configured as a door panel by an inner panel 11 and an outer panel 12. As shown in the cross-sectional view of FIG. 5, a door beam member 13 extending in the vehicle longitudinal direction is installed between the inner panel 11 and the outer panel 12. The door beam member 13 is a cylindrical reinforcing material for maintaining the strength of the side door 10 during a side collision of the vehicle. The inner panel 11 is formed with a bead-shaped portion 11a that protrudes toward the inside of the vehicle and extends in the vehicle longitudinal direction. This bead-shaped portion 11a is arranged at a position overlapping the door beam member 13 in a side view of the vehicle. In this embodiment, the vehicle lower portion of the bead-shaped portion 11a and the door beam member 13 are configured to overlap in a side view. In addition, the bead-shaped portion 11a is arranged at a position overlapping the grip portion 55 of the reclining lever 54 in a side view. A trim member 20 is attached to the vehicle inner side surface of the inner panel 11 so as to cover it with a gap therebetween.

The trim member 20 is disposed in a position overlapping with the grip portion 55 of the reclining lever 54 of the seat 50 in a side view. As described above, the position of the grip portion 55 of the reclining lever 54 also slides as the seat 50 slides in the fore-aft direction of the vehicle, so the trim member 20 is disposed so as to overlap with the grip portion 55 of the reclining lever 54 in a side view over the entire sliding range.

Further, the trim member 20 has a character line 21 extending in the longitudinal direction of the vehicle, as shown in FIG. 2 . The character line 21 has a cross section shaped like a step or a groove. As shown in FIG. 5, the cross-sectional shape of the character line 21 in this embodiment is a substantially V-shaped groove recessed toward the outside of the vehicle. A portion of the trim member 20 on the inside surface of the vehicle below the character line 21 is located slightly further inside the vehicle than a portion above the character line 21. In other words, the vehicle inner surface of the trim member 20 has a shape having a step above and below the character line 21. The character line 21 is arranged above the grip portion 55 of the reclining lever 54 in the vehicle when viewed from the side.

Furthermore, the trim member 20 has a lattice-shaped rib-shaped portion 22 formed only in a portion of the outer surface of the vehicle that is located above the character line 21. In other words, the lattice-shaped rib-shaped portion 22 is formed in a portion of the outer surface of the trim member 20 that is located above the character line 21, but is not formed in a portion of the outer surface of the trim member 20 that is located below the character line 21, but is not formed in a portion of the outer surface of the trim member 20 that is located below the character line 21. The rib-shaped portion 22 has a protruding portion 22a that protrudes toward the outside of the vehicle at the position of the character line 21. The protruding portion 22a is disposed at a position that overlaps with the bead-shaped portion 11a of the inner panel 11 in a side view. The upper end of the rib-shaped portion 22 has a protruding portion 22b for fixing the pad member 30 in a predetermined position. In addition, the trim member 20 has a door pocket portion 23 having an opening 23a in a portion that extends from the character line 21 to the front of the vehicle (see FIG. 2).

As described above, the pad member 30 is disposed in the space between the inner panel 11 and the trim member 20. As shown in the perspective view of FIG. 4 and the cross-sectional view of FIG. 5, the pad member 30 has a predetermined thickness, and the side surface located on the inside of the vehicle is formed in a stepped shape that gradually approaches the inside of the vehicle as it moves toward the upper side of the vehicle. In this embodiment, the side surface located on the inside of the vehicle of the pad member 30 has a first side portion 31, a second side portion 32 located on the upper side of the vehicle and on the inside of the vehicle than the first side portion 31, a first step portion 33 located between the upper end of the first side portion 31 and the lower end of the second side portion 32 and extending in the front-rear direction of the vehicle, a third side portion 34 located on the upper side of the vehicle than the second side portion 32 and on the inside of the vehicle, and a second step portion 35 located between the upper end of the second side portion 32 and the lower end of the third side portion 34 and extending in the front-rear direction of the vehicle.

FIG. 6 shows the positional relationship between the pad member 30 inside the side door 10 and the grip portion 55 of the reclining lever 54. As shown in FIG. 6, the pad member 30 is disposed at a position overlapping at least a portion of the grip portion 55 of the reclining lever 54 within the sliding range of the seat 50 when viewed from the side. Further, as shown in FIGS. 5 and 6, the lower end portion of the pad member 30 extends to the lower side of the vehicle than the grip portion 55 of the reclining lever 54 and extends to a position overlapping with the door beam member 13 in side view. ing.

As shown in FIGS. 3 and 5, the first stepped portion 33 of the pad member 30 is located above the character line 21 of the trim member 20 in the vehicle when viewed from the side. In this embodiment, the first stepped portion 33 is adjacent to the vehicle upper side than the protruding portion 22a of the rib-shaped portion 22 formed on the vehicle outer surface of the trim member 20.

The first side surface portion 31 of the pad member 30 is spaced from a portion of the trim member 20 below the character line 21 of the vehicle. The second side surface portion 32 of the pad member 30 is in contact with the rib-shaped portion 22 of the trim member 20. A fixing portion 36 is formed in the second side surface portion 32 , into which the protrusion 22 b of the trim member 20 is inserted to fix the pad member 30 to the trim member 20 . In addition to the second side surface portion 32, the fixing portion 36 between the trim member 20 and the pad member 30 includes a vehicle front portion of the upper surface of the pad member 30 located above the vehicle, and a vehicle upper portion of the side surface located on the rear side of the vehicle. (See Figure 4).

In a side view, the second step portion 35 of the pad member 30 is adjacent to the upper end of the rib-shaped portion 22 of the trim member 20 and above the vehicle. In this embodiment, a protrusion 22b is provided at the upper end of the rib-shaped portion 22, so the second step portion 35 of the pad member 30 is located above the protrusion 22b. The third side portion 34 of the pad member 30 abuts against the vehicle outer side surface of the trim member 20. In addition, the vehicle lower portion of the side surface of the pad member 30 located on the vehicle outer side abuts against the bead-shaped portion 11a of the inner panel 11 (see FIG. 5).

Next, the operation of the vehicle side door structure according to this embodiment will be described in detail.
In the side door 10 having the above-described structure, in the event of a side collision of the vehicle, the outer panel 12 and the inner panel 11 are pushed inward into the vehicle, causing the trim member 20 provided on the vehicle inner side surface of the inner panel 11 to move inward into the vehicle, and the portion of the trim member 20 on the vehicle inner side below the character line 21 comes into contact with the grip portion 55 of the reclining lever 54.

At this time, the lower end of the pad member 30 provided in the space between the inner panel 11 and the trim member 20 extends further toward the lower side of the vehicle than the grip portion 55 of the reclining lever 54 in a side view, so that the first side portion 31 of the side of the pad member 30 located on the inside of the vehicle supports the trim member 20 that is in contact with the grip portion 55 of the reclining lever 54. This prevents the trim member 20 from being pushed toward the outside of the vehicle, making it possible to suppress deformation of the trim member 20 toward the outside of the vehicle.

In addition, by arranging the first step portion 33 of the pad member 30 above the character line 21 of the trim member 20, the pad member 30 and the trim member 20 can be easily engaged with each other, and the contact area between them can be increased. This suppresses slippage between the pad member 30 and the trim member 20, making it possible to effectively suppress deformation of the trim member 20 toward the outside of the vehicle. If deformation of the trim member 20 toward the outside of the vehicle is suppressed, for example, it is possible to reduce the occurrence of a situation in which the grip portion 55 of the reclining lever 54 falls into and is held by the character line 21 of the trim member 20, and the rotation of the reclining lever 54 is promoted by deformation of the vehicle body such as the side door 10.

Therefore, according to the vehicle side door structure of the present embodiment, even if the grip portion 55 of the reclining lever 54 comes into contact with and is pressed against the trim member 20 of the side door 10 in the event of a side collision, the reclining locked state is released. It is possible to prevent the vehicle from being stowed away, making it possible to fully obtain the effects of safety devices such as seat belts and airbags.

In addition, in the vehicle side door structure of this embodiment, a lattice-shaped rib-shaped portion 22 is formed in a portion of the trim member 20 located above the character line 21 on the vehicle outer side, so that deformation of the portion of the trim member 20 above the character line 21 is suppressed during a side collision, and the portion is less likely to be dented toward the outside of the vehicle. In addition, the rib-shaped portion 22 is not formed in the portion of the trim member 20 located below the character line 21 on the vehicle outer side, and the rib-shaped portion 22 is formed with a protruding portion 22a that protrudes toward the outside of the vehicle at the position of the character line 21, so that the trim member 20 is more likely to deform toward the outside of the vehicle relative to the portion located below the character line 21. As a result, a slope that approaches the upper part of the vehicle as it approaches the outer side of the vehicle is less likely to be formed on the vehicle inner side of the trim member 20, so that it is possible to suppress the generation of a force that moves the grip portion 55 of the reclining lever 54 that abuts against the vehicle inner side of the trim member 20 toward the upper part of the vehicle. In addition, because the first step 33 of the pad member 30 is adjacent to the upper side of the vehicle of the protruding portion 22a of the rib-shaped portion 22, it is possible to reliably prevent misalignment (slippage) between the pad member 30 and the trim member 20, so that the trim member 20 can be effectively supported by the pad member 30.

Furthermore, in the vehicle side door structure of this embodiment, a door beam member 13 is installed between the inner panel 11 and the outer panel 12, and the inner panel 11 has a bead-shaped portion 11a formed at a position overlapping the door beam member 13 in a side view. In the side door 10 reinforced with such a door beam member 13, in the event of a side collision, the outer panel 12 and the door beam member 13 move toward the inside of the vehicle as shown in FIG. 7, for example, and the door beam member 13 abuts against the bead-shaped portion 11a of the inner panel 11 and presses the bead-shaped portion 11a toward the inside of the vehicle. The bead-shaped portion 11a pressed by the door beam member 13 presses the lower portion of the side surface of the pad member 30 located on the vehicle outer side toward the upper inside of the vehicle. When the pad member 30 receives the pressing force from the inner panel 11, the first side portion 31 of the side located on the vehicle inner side moves toward the vehicle inner side, and the first side portion 31 abuts against the protruding portion 22a of the rib-shaped portion 22 formed on the vehicle outer side of the trim member 20, pressing the protruding portion 22a toward the vehicle inner side. At this time, the trim member 20 also moves toward the vehicle inner side due to the side door 10 being pushed toward the vehicle inner side, and the portion of the trim member 20 below the character line 21 on the vehicle inner side abuts against the grip portion 55 of the reclining lever 54. Since the protruding portion 22a of the rib-shaped portion 22 of the trim member 20 is pressed toward the vehicle inner side by the pad member 30, deformation of the portion of the trim member 20 near the character line 21 toward the vehicle outer side can be more effectively suppressed. Note that the solid line in FIG. 7 shows the behavior when the vehicle side door structure of this embodiment is applied, and the two-dot chain line shows the behavior when the vehicle side door structure of this embodiment is not applied.

In addition, in the vehicle side door structure of this embodiment, the second side surface portion 32 of the pad member 30 abuts against the vehicle outer surface (rib-shaped portion 22) of the trim member 20, and the first side surface portion 31 of the pad member 30 is disposed at a distance from the portion of the trim member 20 below the character line 21. As a result, the portion of the trim member 20 above the character line 21 is less likely to deform toward the outside of the vehicle, while the portion below the character line 21 is more likely to deform toward the outside of the vehicle due to the space between the first side surface portion 31 of the pad member 30 and to have a shape that is inclined toward the outside of the vehicle as it approaches the bottom of the vehicle. Such an inclined shape of the portion below the character line 21 can effectively prevent the grip portion 55 of the reclining lever 54 abutting against the trim member 20 from being guided toward the character line 21.

In addition, in the vehicle side door structure of this embodiment, the second step portion 35 of the pad member 30 is adjacent to the upper end of the rib-shaped portion 22 of the trim member 20 on the vehicle upper side, and a fixing portion 36 to the trim member 20 is formed on the second side surface portion 32 of the pad member 30. As a result, by matching the second step portion 35 of the pad member 30 to the upper end of the rib-shaped portion 22 of the trim member 20, it becomes easy to align the projection portion 22b of the trim member 20 with the fixing portion 36 of the second step portion 35 of the pad member 30, so that the assembling property of the pad member 30 to the trim member 20 can be improved. Also, since the fixing to the trim member 20 is performed only at the upper portion of the pad member 30 and the lower portion of the pad member 30 is left in a free state, it is possible to reduce the possibility of a gap occurring between the pad member 30 and the trim member 20 due to the load at the time of a side collision. As a result, it is possible to more reliably suppress deformation of the trim member 20 near the character line 21.

Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and various modifications and changes can be made based on the technical idea of the present invention. For example, in the embodiment described above, an example is shown in which the rib-shaped portion 22 is formed on the vehicle outer surface of the trim member 20, but it is also possible to omit the rib-shaped portion 22. In this case, the second side surface portion 32 of the pad member 30 may come into contact with the vehicle outer side surface of the trim member 20.

Further, in the embodiment described above, an example was shown in which the side surface of the pad member 30 located on the inside of the vehicle has the third side surface portion 34 and the second stepped portion 35 on the upper side of the vehicle of the second side surface portion 32. A configuration in which the third side surface portion 34 and the second step portion 35 are not formed, that is, the side surface of the pad member 30 located on the inside of the vehicle is composed of the first side surface portion 31, the second side surface portion 32, and the first step portion 33. It is also possible to do so.
