Description

The present invention relates to the passenger compartment structure of an automobile.

Conventionally, impact bars are provided on the lower side and the upper side of the door body, respectively, and the lower impact bar corresponding to the bumper line is arranged in the outward direction of the door from the upper impact bar, and is arranged in a downward inclined shape. The door structure of an automobile is known (for example, Patent Document 1).

According to such an automobile door structure, in the event of a side collision, a collision load acts on the lower impact bar located on the outside, and after the impact bar begins to deform, the upper impact bar also begins to deform. Therefore, the collision load acts with a time lag. As a result, the acceleration of the impact on the occupants in the vehicle interior can be reduced.

Specifically, the engaging portion 15 is arranged below the first engaging portion 15a, the second engaging portion 15b disposed below the first engaging portion 15a, and the second engaging portion 15b. A third engaging portion 15c provided, a fourth engaging portion 15d disposed below the third engaging portion 15c, and a fifth engaging portion arranged below the fourth engaging portion 15d. It is composed of a 15e and a sixth engaging portion 15f arranged below the fifth engaging portion 15e.

(First aspect of the side wall panel 10 and the inner trim 11 at the time of a side collision)
Next, the first aspect of the side wall panel 10 and the inner trim 11 at the time of a side collision will be described with reference to FIG. Note that FIG. 3 is also a rear view of the vehicle 1 as viewed from the rear.

FIG. 3A shows a view before the other vehicle 17 collides with the left side surface of the vehicle 1. Here, the vertical width V1 from the upper portion of the third engaging portion 15c to the bottom portion of the fourth engaging portion 15d is the bumper portion of the other vehicle 17 constituting the input portion for inputting the collision load to the vehicle 1. It is shorter than the vertical width V2. The vertical width V3 from the bottom of the third engaging portion 15c to the upper portion of the fourth engaging portion 15d is also shorter than the vertical width V2 of the bumper portion.

The input unit has been described by exemplifying the bumper portion of the other vehicle 17, but the present invention is not limited to this. For example, the entire front surface of another vehicle 17 can be applied as an input unit. In this case, the above-mentioned vertical width V1 and vertical width V3 are shorter than the vertical width of the entire front surface of the other vehicle.

Then, when the bumper portion of the other vehicle 17 collides with the left side surface of the vehicle 1, the collision load is first transmitted to the outer panel 13. Next, the outer panel 13 to which the collision load is transmitted transmits the collision load to the inner panel 12. Then, the inner panel 12 to which the collision load is transmitted transmits the collision load to the inner trim 11.

Next, as shown in FIG. 3B, when the bumper portion of the other vehicle 17 collides with the left side surface of the vehicle 1, the side wall panel 10 engaged by the engaging portion 15 and the inner trim 11 are separated. It becomes.

Specifically, of the side wall panel 10 engaged by the engaging portion 15 and the inner trim 11, the portion above the upper portion of the first engaging portion 15a and the bottom portion of the second engaging portion 15b. Is separated from the lower part. On the other hand, the side wall panel 10 and the inner trim 11 remain engaged between the two points between the first engaging portion 15a and the second engaging portion 15b. Then, the inner trim 11 is pressed by the surface between the first engaging portion 15a and the second engaging portion 15b and moves substantially in parallel to the vehicle interior side. As a result, the shoulders and waist of the occupant are pressed at the same time, so that the occupant can be stably and gently moved to the non-collision side.

As described above, according to the vehicle interior structure of the automobile in the first embodiment, when another vehicle 17 collides from the side, the inner trim 11 has the third engaging portion 15c and the fourth engaging portion 15d. It is pressed by the surface between the two points and moves substantially in parallel to the passenger compartment side. As a result, the inner trim 11 is pressed by the surface between the two points of the third engaging portion 15c and the fourth engaging portion 15d and moves substantially in parallel to the passenger compartment side, so that the shoulder and waist of the occupant Is pressed at the same time, so that the occupant can be stably and gently accelerated to the non-collision side.

Further, when another vehicle 17 having a low vehicle height collides from the side, the inner trim 11 is pressed against the surface between the second engaging portion 15e and the sixth engaging portion 15f to the passenger compartment side. It will move almost in parallel. Then, when another vehicle 17 having a high vehicle height collides from the side, the inner trim 11 is pressed against the surface between the first engaging portion 15a and the second engaging portion 15b to the passenger compartment side. It will move almost in parallel. As a result, even if another vehicle 17 having a high vehicle height collides from the side or another vehicle 17 having a low vehicle height collides from the side, the occupant is stably placed on the non-collision side. It can be moved gently.

Although the case where the collision load is transmitted to the left rear door 5b has been described as an example, the same effect is also obtained when the collision load is transmitted to the right rear door 5a. Further, the same effect is obtained when the collision load is transmitted to the right front door 4a and the left front door 4b.
