The door trim 20 covers the vehicle compartment side of the door inner panel 10 and is arranged with a slight gap (indicated by reference numeral G in FIG. 4A) from the door inner panel 10.

  The door inner panel 10 and the door trim 20 are fixed to each other via a bracket 30 disposed in the gap G between them. By attaching the bracket 30 to the gap G between the door trim 20 and the door inner panel 10 in this way, the door trim 20 can be reliably supported by the door inner panel 10 even when the door trim 20 is pulled toward the vehicle compartment. It has become. The bracket 30 is formed of a plate-like member arranged substantially horizontally. In FIG. 2, the bracket 30 is fixed to the door inner panel 10 by, for example, two screws 34 at one end portion on the door inner panel 10 side. Is shown. The configuration of the bracket 30 and the fixing of the bracket 30 to the door trim 20 will be described in detail later.

  As for the door trim 20, the armrest 21 is formed in the approximate center of the compartment side. The armrest 21 serves as an armrest for an occupant and is formed by a protruding portion extending in the x direction in the figure. A pull handle 22 is attached to the horizontal portion of the upper surface of the armrest 21. The pull handle 22 includes a recessed portion 23 into which an occupant's hand can be inserted, and a flange portion 24 extending outward from the periphery of the opening of the recessed portion 23.

  The pull handle 22 is attached to the armrest 21 by inserting the recessed portion 23 of the pull handle 22 into an opening (indicated by reference numeral 21a in FIG. 4A) formed on the upper surface of the armrest 21, and the flange portion of the pull handle 22. 24 and the nail | claw (it shows with the code | symbol 23a in FIG.4 (b)) formed in the outer wall surface of the recessed part 23 is made | formed by clamping the periphery of the said opening 21a formed in the armrest 21. FIG. In addition, various switches 25 and the like for opening and closing a window attached to the door, for example, are disposed on a part of the flange portion 24 of the pull handle 22.

  In FIG. 2, a pocket 26 is disposed below the armrest 21 of the door trim 20, and an audio speaker 27 is disposed adjacent to the pocket 26.

  FIG. 3 is a perspective view showing the pull handle 22 and the bracket 30 shown in FIG. As shown in FIG. 3, the bracket 30 is fixed to the bottom surface of the recessed portion 23 of the pull handle 22 and, for example, one screw (fixing tool) 35 at the other end portion 33 on the door trim 20 side. ing. That is, the screw 35 is inserted through a screw insertion port (fixing device insertion port) (indicated by reference numeral 40 in FIG. 1A) formed on the bottom surface of the recessed portion 23 of the pull handle 22, and the other end of the bracket 30. The screw is inserted into a screw screw hole (fixing tool insertion hole) 36 formed in the portion 33.

  In FIG. 3, the bracket 30 has, for example, two bent portions 37 that are concave on the upper side. As a result, the bracket 30 includes one end portion 31 that is a fixing portion for the door inner panel 10, the other end portion 33 that is a fixing portion for the door trim 20, and an intermediate portion disposed between the one end portion and the other end portion. It is formed so as to have three plane parts composed of the part 32. The bracket 30 configured in this manner is configured to have a function of absorbing impact energy due to secondary collision by the bent portion 37.

  1A is a plan view of the recessed portion 23 of the pull handle 22 as viewed from the opening side, and FIG. 1B is a side view of the pull handle 22 as viewed from the line bb in FIG. 1A. . 1A and 1B, the periphery of the screw insertion opening 40 of the screw 35 formed in the recessed portion 23 of the pull handle 22 is formed as a so-called stepped-down portion 50. That is, on the bottom surface (inner bottom surface) viewed from the opening side of the recessed portion 23, the periphery of the screw insertion port 40 is formed as a recess 51 having a step with respect to the other periphery, and the bottom surface outside the recess 51 On the (outer bottom surface), a convex portion 52 reflected by the formation of the concave portion 51 is formed. Thus, by forming the periphery of the screw insertion port 40 formed in the recessed portion 23 of the pull handle 22 as the stepped-down portion 50, the screw 35 is screwed in a state of being embedded in the stepped-down portion 50. Be able to.

  The screw insertion port 40 is formed as a notch having an open end on one side, and the open end of the notch is configured to be directed to the vehicle compartment side (door trim 20 side). FIG. 6 is a view drawn corresponding to FIG. 1 (a), and shows a notch in which the screw insertion port 40 has an open end on the vehicle compartment side (z direction in the figure) by showing the screw 35 removed. It is shown that it is formed as. In this case, the width w of the notch is smaller than the diameter of the head portion of the screw 35 and slightly larger than the diameter of the shaft portion in which the screw groove of the screw 35 is formed. The notch that is the screw insertion opening 40 is formed such that the extending end reaches the side wall surface 53 of the stepped portion and is continuous with the hole 54 formed in the side wall surface 53. In this case, the hole 54 has a width W larger than the diameter of the head of the screw 35. The size of the hole 54 in the side wall surface 53 of the stepped-down portion 50 is set in this way when the bracket 30 into which the screw 35 is screwed moves to the vehicle compartment side, as will be apparent later. This is because the screw 35 inserted into the recessed portion 23 of the pull handle 22 is released from the hole 54 in the side wall surface 53 of the stepped-down portion 50 and the fixing of the pull handle 22 and the bracket 30 is released.

  FIG. 4A is a view in which the door trim 20 is attached to the door inner panel 10 via the bracket 30, and is a cross-sectional view in the plane including the central axis of the screw 35. FIG. 4B is an enlarged view of the fixing portion between the recessed portion 23 of the pull handle 22 and the other end portion 33 of the bracket 30 by the screw 35 in FIG. 4A.

  As shown in FIG. 4B, on the bottom surface of the recessed portion 23 of the pull handle 22, the screw 35 is inserted into the screw insertion port 40 formed in the stepped-down portion 50 and formed at the other end portion 33 of the bracket 30. The pull handle 22 and the bracket 30 are fixed by being screwed into the screw screw hole 36. Here, since the door trim 20 is fixed by a flange portion 24 formed on the pull handle 22 and a claw 23a, and the bracket 30 is fixed to the door inner panel 10 by screws 34, the door inner panel 10 The door trims 20 are supported by each other via a bracket 30. In this case, the fastening of the pull handle 22 and the bracket 30 with the screw 35 is strong, and the screw 35 is removed from the notch formed in the recessed portion 23 of the pull handle 22 with a force enough to pull the door trim 20 toward the passenger compartment. The door trim 20 is sufficiently supported by the door inner panel 10 without being removed from the screw insertion opening 40.

  FIG. 5 is a view drawn in association with FIG. 4 (b), and is a view showing a deformation of the interior structure when an impact F is applied to the door inner panel 10. Due to the impact F from the door inner panel 10, an extremely large force acts on the bracket 30 together with the screw 35 on the vehicle compartment side, and the screw 35 extends along the screw insertion opening 40 formed by a notch formed in the recessed portion 23 of the pull handle 22. It moves to the passenger compartment side and comes out of the pull handle 22 through the hole 54 formed in the side wall surface 53 of the stepped-down portion 50. Thereby, the impact F from the door inner panel 10 is not conducted as it is to the pull handle 22 and eventually to the door trim 20, and the push of the door trim 20 toward the passenger compartment can be reduced. Can be reliably reduced.

  In this case, since the screw 35 is embedded in the stepped-down portion 50 and the diameter of the stepped-down portion 50 is relatively small, the length of the notch constituting the screw insertion port 40 can be reduced. When an impact is applied to the inner panel 10, the pull handle 22 and the bracket 30 are released from being fixed in an extremely short time.

  As described above, according to the vehicle interior structure shown in the above embodiment, even if the door inner panel 10 receives an impact, the impact is not directly transmitted to the door trim 20, and the impact applied to the occupant is reduced. A configuration that can be reduced can be achieved. For this reason, a passenger | crew's safety can be ensured.

  In the above embodiment, the bracket 30 is provided with a plurality of bent portions 37, and the bent portions 37 have a function of absorbing impact energy due to secondary collision. However, the bracket 30 is not limited to this, and it is needless to say that the bracket 30 may not have the above-described function.

  In the above embodiment, the door inner panel 10 is described as an example of the vehicle body panel, and the door trim 20 is described as an example of the interior member. However, the present invention is not limited to this.

  As described above, according to the vehicle interior structure of the present invention, even when an impact is received on the vehicle body panel, the impact is not directly transmitted to the interior member, and the impact applied to the occupant can be reduced. Will be able to. For this reason, a passenger | crew's safety can be ensured.
