Description

  The present invention relates to a vehicle door trim.

  A door trim as an interior material is attached to the vehicle interior side of the door panel constituting the vehicle door. As shown in Patent Document 1, this type of door trim is usually provided with an armrest portion that is used as an armrest for an occupant so as to protrude from the vehicle interior to the vehicle interior. Also, the door trim has a container-like pull handle that opens upward so that when the passenger closes the vehicle door, a finger is inserted from the upper surface side of the armrest portion to easily pull the door trim toward the vehicle interior side. It is provided in a form that can be accommodated.

  In the door trim, the pull handle portion is fixed to the door panel using a substantially U-shaped bracket. Both ends of the bracket are screwed to the door panel while holding the pull handle portion from the vehicle interior side. Since such a pull handle portion is firmly fixed to the door panel by a bracket, it is possible to prevent the arm rest portion from being pulled together with the pull handle portion toward the vehicle interior to bend and deform.

  A groove portion extending in the vehicle front-rear direction is formed in a portion of the bracket facing the vehicle interior side. The groove portion engages with a locking projection extending in the vehicle front-rear direction on the back side of the side wall of the armrest portion, so that the bracket also functions as a tension member that keeps a space between the side wall of the armrest portion and the door panel. Therefore, during normal use, even if a load is applied to the side wall of the armrest portion from the vehicle interior side, the armrest portion is prevented from being bent and deformed.

In contrast, the vehicle is surely overlapped in the vehicle width direction. Therefore, the inclined support 44 is preferentially broken.

  In such a state, when the door inner panel P is further pushed into the vehicle interior side so as to approach the lower vertical wall portion 2B, the main body portion 42c of the passing portion 42 passes each other with the breakage guide portion 46 as a boundary. Divided into two parts. Here, for convenience of explanation, it is assumed that the main body 42c is divided into a fragment 42c1 on the vehicle interior side and a fragment 42c2 on the vehicle exterior side after the division.

  When the fragment 42c1 on the vehicle interior side after being divided enters under the fragment 42c2 outside the vehicle interior and the fragment 42c1 and the fragment 42c2 pass each other, the interference between the fragment 42c1 and the fragment 42c2 is suppressed, and the lower side The upright wall 2B can be brought close to the door inner panel P in order to absorb an impact or the like.

For example, if, under the pieces 42c1 of the vehicle interior side, if had sunk car exterior side pieces 42c2, since each other fragments 42c1,42c2 may interfere with the vehicle width direction, in order to absorb the impact, The lower standing wall 2B cannot be sufficiently brought close to the door inner panel P.

  Further, in the case of the present embodiment, the sliding rib 47 is formed on the lower surface of the segment 42c2 outside the passenger compartment. Therefore, when the fragment 42c1 on the vehicle interior side sinks below the fragment 42c2 on the vehicle exterior side, the frictional resistance between the fragment 42c1 and the fragment 42c2 is reduced as compared with the case where the sliding rib 47 is not provided. Yes. Therefore, in the case of the present embodiment, by providing the sliding rib 47, the fragments 42c1 and 42c2 of the main body 42c are easily slidable with each other after breaking, and further, the lower standing wall 2B is set against the door inner panel P. Easy to approach and absorb impact.

  In this way, the inclined support 44 is preferentially destroyed over the horizontal support 144 in a side collision. As shown in FIG. 9, the closer to the inclined support portion 44, the higher the plurality of contact plates 52, 53, 54 that are erected on the inclined surface of the contact portion 50, the higher the height from the inclined surface 51a. The height (in the vehicle width direction) is set high. The contact plates 52, 53, 54 are arranged on the inclined surface 51a so as to be aligned in a row while maintaining a distance from each other in the vehicle front-rear direction.

  As described above, when the inclined support portion 44 is broken during a side collision, the contact plates 52, 53, and 54 of the contact portion 50 are brought down, and the vehicle having a large distance between the inclined surface 51a and the handle main body 41 is provided. The rear lower wall portion 2B on the rear side is easy to approach the handle main body 41 fixed to the door inner panel P.

  The horizontal support portion 144 is also broken at the breakage guide portion 146, and the impact at the time of a side collision is absorbed.

  As described above, when the inclined support part 44 and the horizontal support part 144 are destroyed by the side collision, the door trim 1 is crushed from the vehicle interior side toward the door inner panel P, and the door trim 1 absorbs the impact. Is done.

  In the door trim 1 of the present embodiment, when a side collision occurs, the main body portion 42c of the passing portion 42 is broken by the breakage guiding portion 46, and the broken piece 42c1 fixed to the lower standing wall portion 2B is fixed to the door inner panel P. It is possible to sink under the fragment 42c2 after being broken. As a result, the broken piece 42c1 and the piece 42c2 can pass each other without interfering with each other, and the door trim 1 is easily crushed and easily absorbs the impact.

  Further, the door trim 1 of the present embodiment is provided with the sliding rib (friction reducing portion) 47, and further, the broken piece 42c1 fixed to the lower vertical wall portion 2B at the time of a side collision is added to the door inner panel P. It becomes easy to sink under the fragment 42c2 after the fracture to be fixed, and as a result, the door trim 1 is easily crushed and the impact is easily absorbed.

  Further, the door trim 1 of the present embodiment has an inclined type support portion 44 (connecting portion 43 and delivery portion 42) disposed on the vehicle rear side of the handle main body 41, so that an occupant seated on a vehicle seat adjacent to the door trim 1. On the other hand, at the time of a side collision, the inclined support portion 44 (the connection portion 43 and the passing portion 42) is easy to contact, and the door trim 1 can easily absorb the impact at the time of the side collision.
