  According to the vehicle door of the third aspect, it is possible to obtain an excellent effect that the vehicle can be retracted from an object in the vehicle over a wide range including the movable door trim as well as the armrest at the time of a side collision.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIG. 1, a vehicle door 10 according to the present embodiment includes a door panel 16 formed by, for example, overlapping a door outer panel 12 and a door inner panel 14 in the vehicle width direction, an upper door trim 18 as an example of a door trim, and a movable door trim. 20 and a lower door trim 22 and an armrest 24, which are positioned above the rocker 26 in the closed state. Further, the vehicle door 10 has an armrest structure S in which the armrest 24 and the movable door trim 20 can be retracted outward in the vehicle width direction at the time of a side collision.

  The upper door trim 18 is disposed on the door panel 16, particularly the upper portion of the door inner panel 14 on the side of the vehicle compartment 30, and covers the door inner panel 14 above the armrest 24. The lower edge portion 18A of the upper door trim 18 is close to, for example, the door inner panel 14 in order to secure a wide extension amount of the armrest 24, that is, a region in which an unillustrated occupant can place an arm. The shape of the upper door trim 18 is not limited to that shown in the figure, and may be flat as long as the overhang amount of the armrest 24 can be secured sufficiently.

  The armrest 24 is connected to the lower edge portion 18A of the upper door trim 18 via an outer hinge 28, and is maintained in an overhanging state toward the passenger compartment 30 during normal use so that an occupant can rest the arm on the arm. It has become. The armrest 24 is configured to fall outward in the vehicle width direction using the outer hinge as a fulcrum when a side impact load F (FIG. 2) acts on the door outer panel 12. The outer hinge 28 is, for example, an integral hinge.

  The lower door trim 22 is disposed at the lower portion of the door panel 16 on the side of the vehicle compartment 30 and covers the door inner panel 14 below the movable door trim 20. A fulcrum 32 is provided in the lower door trim 22, and a link 34 is pivotally attached to the fulcrum 32 so as to be swingable in the vehicle vertical direction. Further, the link 34 and the door inner panel 14 are arranged so as not to interfere with each other when the link 34 swings.

  The movable door trim 20 is connected to the vehicle interior side edge of the armrest 24 via an inner hinge 36, extends from the inner hinge 36 to the upper edge 22 A of the lower door trim 22, and is detachable from the lower door trim 22. When the armrest 24 is folded, the armrest 24 is configured to move to the outside in the vehicle width direction along with the armrest 24 to be in a retracted state. The inner hinge 36 is, for example, an integral hinge.

  Specifically, a node 38 is provided at the lower end portion of the movable door trim 20, and the node 40 provided at the tip of the link 34 is connected by a wire 42 as an example of a retracting member. The link 42 is suspended by the wire 42 so that, for example, the link 34 is in a horizontal state or slightly inclined below the horizontal during normal use.

  In addition, the movable door trim 20 should just be separated from the lower door trim 22 at the time of a side collision, and the movable door trim 20 and the lower door trim 22 may be integrated during normal use. In order to separate the movable door trim 20 and the lower door trim 22 at the time of a side collision, for example, the boundary between the movable door trim 20 and the lower door trim 22 is sewn so that it does not break during normal use and breaks at the side collision. Alternatively, it may be possible to bond them.

  On the other hand, a load transmission member 44 extending inward in the vehicle width direction is attached to the inner surface of the door outer panel 12 at a height position of a bumper (collision vehicle 46) of a sedan type vehicle, for example. Is an inclined surface 44A that extends inward in the vehicle width direction from the lower side to the upper side in the vehicle vertical direction, and the inclined surface 44A is in contact with or close to the tip of the link 34. Of the load transmitting member 44, it is desirable that the upper corner 44B that contacts the wire 42 at the time of a side collision is largely rounded.

  The door inner panel 14 is formed with an entrance hole 14A for allowing the load transmitting member 44 to enter the vehicle width direction when a side collision load F acts on the door outer panel 12 due to a side collision. ing.

  The configuration for retracting the movable door trim 20 and folding the armrest 24 is not limited to the illustrated one, and the shape of the load transmitting member 44 and the arrangement of the link 34 and the wire 42 are different from the illustrated one. It is good also as arrangement.

(Function)
In FIG. 1, in the vehicle door 10, the armrest 24 is maintained in an overhanging state toward the passenger compartment 30 with respect to the upper door trim 18 during normal use. Is secured. Here, when the collision vehicle 46 travels in the direction of arrow A and a side collision occurs with respect to the door outer panel 12 of the vehicle door 10, as shown in FIG. 2, the side collision load F (1 Next collision load) acts on the door outer panel 12, and the load transmitting member 44 is pushed through the entrance hole 14 </ b> A of the door inner panel 14 toward the vehicle compartment 30 as the door outer panel 12 is deformed.

  Then, after the link 34 contacts the inclined surface 44 </ b> A of the load transmission member 44, the link 34 gradually falls downward along the inclined surface 44 </ b> A as the load transmission member 44 enters. As a result, the wire 42 is pulled downward, so that the movable door trim 20 connected to the wire 42 at the node 38 is separated from the lower door trim 22 and pulled. That is, the movable door trim 20 is detached from the lower door trim 22.

  Accordingly, the armrest 24 connected to the movable door trim 20 via the inner hinge 36 is folded downward with the outer hinge 28 as the center, and the movable door trim 20 and the armrest 24 are moved in the vehicle width direction. As a result, the amount of overhang of the armrest 24 toward the passenger compartment 30 is greatly reduced, and the armrest 24 is retracted outward in the vehicle width direction.

  By using such an armrest structure S, in the vehicle door 10, a side collision occurs at an earlier time point, that is, after a secondary collision load due to a side collision acts on an object (not shown) in the vehicle. Thus, the armrest 24 can be retracted at the timing when the primary collision load acts on the door outer panel 12 and can be retracted not only from the armrest 24 but also from an object in the vehicle over a wide range including the movable door trim 20. It is. For this reason, it is difficult for the armrest 24 and the movable trim 20 to collide with an object in the vehicle, and even if it collides, the secondary collision load can be reduced. Moreover, since the rigidity of the armrest 24 at the time of normal use is sufficiently ensured, the usability is also excellent. That is, in the vehicle door 10, the side collision requirement and the usability requirement are compatible.

  Further, in this embodiment, as the load transmitting member 44 enters, the wire 42 slides on the corner portion 44B of the load transmitting member 44. However, since the corner portion 44B is greatly rounded, the wire smoothly 42 can be retracted, and the armrest 24 can be quickly retracted.

  When the armrest 24 and the movable door trim 20 are retracted outward in the vehicle width direction, the outer hinge 28 may be broken and the armrest 24 may be detached from the upper door trim 18.

It is sectional drawing which shows the vehicle door by which the armrest was maintained in the vehicle interior side extended state. It is sectional drawing which shows the state which the collision load by a side collision was input into the door panel, and the armrest and the movable panel were folded and retracted to the vehicle width direction outer side.
