に対し高い衝撃吸収性が要求されるようになった。2. Description of the Related Art In recent years, a vehicle has been required to have high security not only from a frontal collision but also from a side collision. Therefore, a high impact absorbing property is required for the interior interior members of the door portion, such as the armrest 30 and the door panel 32 shown in FIG. 5, which directly hit the occupant's waist at the time of the collision from the side.
【０００３】しかし、従来のアームレスト等は、内部が

な大なる衝撃を十分に吸収できるものではなかった。However, a conventional armrest or the like is made of a plastic product having a hollow inside or a foam provided between a core and a skin material, and can sufficiently absorb a large impact applied at the time of a side collision. It was not something.

に示す荷重変位曲線Ｋ1 が得られた。Therefore, the present inventor has proposed a surface of the plastic armrest 34 on the vehicle outer plate side (a surface on the side where the armrest is mounted) as shown in FIG. 6 in order to absorb a greater impact.
36, the tip height is provided a constant rib segment R 1 in the vehicle width direction, an attempt was made to perform an impact absorption test. As a result, FIG.
The load displacement curve K 1 shown in obtained.

In this load-displacement curve, the vertical axis load, horizontal axis they become displaced rib pieces, energy absorption is represented by the area between the load-displacement curve K 1 and the horizontal axis. Therefore, as the figure formed by the load displacement curve and the horizontal axis approaches a square, the absorption amount of the impact energy increases. On the other hand, if the initial load is too high, a large impact is transmitted to the occupant. Therefore, the ideal load displacement curve K preferably has a flat portion b having a predetermined load following the initial rise a.

ことが判明した。Considering the load displacement curve K 1 from the above viewpoint, the load displacement curve K 1 shows that the initial load c is extremely higher than the ideal load displacement curve K, and a large load is applied to the occupant in the initial stage of impact. ing. Therefore, it has been found that the impact applied to the occupant cannot be sufficiently reduced depending on the rib structure.

The In the load-displacement curve K 2, the load increases with the displacement of the rib pieces, load is hardly observed certain flat portions. Therefore, it can be seen that, depending on the rib structure, the load applied to the occupant increases almost continuously, and the impact applied to the occupant cannot be sufficiently absorbed.

に係る。SUMMARY OF THE INVENTION According to the present invention, a rib piece is formed along a vehicle width direction on a surface of a vehicle interior member located on an indoor side of a door portion substantially corresponding to a waist portion of an occupant. Along the ribs, the intersections of the ribs are arranged such that the high and low ones are alternately located along the ribs, and the intersections of the ribs intersecting each other at the intersections individually. The present invention relates to a shock absorbing structure for a door portion of a vehicle in which the height is made equal at the intersection and the tip of the rib is gently deformed so as to gradually change the height of the rib between the intersections.

収が行われる。According to the shock absorbing structure of the present invention, the intersections of the rib pieces are arranged such that the high and low ribs are alternately located along the rib pieces, so that the impact from the side face is provided. When the interior surface of the vehicle interior member such as an armrest presses near the waist of the occupant, the high intersection is pressed and deformed, and then the low intersection is pressed and deformed. Get started. Therefore, all of the intersections where the compressive deformation load is high due to the intersection of the rib pieces do not simultaneously start pressing and deforming due to the impact.
Moreover, in the shock absorbing structure of the present invention, at each intersection of the rib pieces, the height of the rib pieces that intersect each other is equal at the intersection, and the height of the rib pieces between the intersections is gradually reduced. Because the rib tip was gently deformed to change
The tip of the rib piece is easily deformed. Therefore, in the event of an impact, from the start of the deformation of the high intersection to the start of the deformation of the low intersection, the tip of the easily deformable rib between the intersections deforms to absorb the shock. Therefore, the load displacement curve shows a substantially flat load after the initial rise, and approaches the ideal load displacement curve, so that the impact is efficiently absorbed.

変形状となっている。The rib piece 14 is for absorbing collision energy from the side, and is provided on a surface 13 of the outer shell 12 on the vehicle body outer plate side (the surface on the armrest mounting side) 13 along the vehicle width direction. I have. The rib piece 14 does not need to be provided on the entire surface 13 of the outer shell portion 12 on the vehicle body outer plate side, and may be provided only on a portion that comes into contact with the occupant's waist at the time of a collision. In addition, a portion of the power window where an operation switch or the like is located may be excluded.
