Description

  The present invention relates to a vehicle door structure that can more accurately protect an occupant when a door panel enters the passenger compartment side during a side collision of the vehicle.

  When a collision from the side occurs with respect to the vehicle, an external force is applied from the outside of the door, the door panel is deformed, the door trim is displaced toward the passenger compartment, and the door trim contacts the occupant and a load is applied. . When the door trim comes into contact with the occupant, it is important that the occupant receive a minimum load without applying an excessive load.

  When the door trim abuts against the occupant violently, the abdomen and chest may lead to injury. It is desirable to move it. For this reason, a technique has been proposed in which a door trim (pocket part) is projected next to the occupant's waist, in particular, near the iliac center behind the acetabulum in the pelvic skeleton to restrain the occupant and protect the occupant ( For example, see Patent Document 1).

  In order to protect the occupant's waist accurately, the burden on the pelvis needs to reduce the impact of both the acetabulum and the iliac, and it is preferable that the impact of the door trim is input to the iliac. I can't say that. Therefore, the current situation is that the load on the pelvis cannot be sufficiently reduced particularly for an occupant with low pelvic resistance, and the occupant's lower back cannot be properly protected.

  For this reason, even when it is a case where a door trim is contact | abutted around the waist | hip | lumbar part with comparatively high tolerance, the structure which abuts a door trim to a site | part with high tolerance further and restrains a passenger | crew is desired. For this purpose, a structure in which a desired part is displaced toward the occupant side with a structure in a limited space with respect to the displacement of the door trim is effective.

  The rotating plate 29 is rotatably supported by the door inner panel 2 between the other end edge 29b and the L-shaped corner portion 29c. That is, the rotary plate 29 is supported by the door inner panel 2 so that the space between the other end edge 29b and the L-shaped corner portion 29c is rotatable about a rotation center axis P3 parallel to the rotation center axis S3. During normal operation, the rotating plate 29 is restricted from rotating in the clockwise direction by, for example, a regulating member or a rotation urging member, and holds the retreat lid 27 against the retreat operation direction.

  As shown in FIG. 6B, when the door outer panel 3 is displaced toward the compartment 4 due to an external input W (for example, due to a side collision), the rotation center axis P3 is centered via the door outer panel 3. The rotary plate 29 rotates in the clockwise direction. The rotation of the rotating plate 29 causes the door pocket 26 to protrude toward the passenger compartment, and at the same time the holding of the back side of the retracting lid 27 by the other end edge 29b of the rotating plate 29 is released (removed from the back side), and the retracting lid 27 is retracted. It is urged and rotated in the operating direction.

  For this reason, when there is an input W from the outside to the inside of the compartment 4 due to a side collision or the like, the door pocket 26 corresponding to the thigh 10 of the door trim 5 (the interior side of the door panel) is pushed out. At the same time, the retracting lid 27 is retracted. Accordingly, the portion corresponding to the thigh 10 of the occupant 8 can be reliably restrained by the door pocket 26, and at the same time, the load on the pelvis can be reduced by retracting the retracting lid 27, and the waist 9 can be protected more accurately. become.
