  When there is a lot of remaining crushing of the resin caulking part (part where four reinforcing ribs are integrally formed around the boss part) at the time of a side collision of the vehicle (hereinafter referred to as “side collision”) Timing will be early. As the side collision performance, the performance increases as the bottom timing is late, so there is room for improvement in terms of delaying the bottom timing.

  The present invention has been made in view of the above circumstances, and provides an automobile door trim mounting structure capable of ensuring the rigidity of the door trim and delaying the bottom timing of the door trim at the time of a side collision. Objective.

In order to solve the above-described problem, an automobile door trim mounting structure according to claim 1 is attached to a vehicle interior side of a door inner panel constituting a door inner plate of a side door and has an outer trim member having an opening. The outer trim member protrudes outward in the vehicle width direction and has a curved shape formed along the vehicle longitudinal direction, and a vertical wall is formed at an outer edge portion, and the vertical wall abuts a peripheral portion of the opening portion and the outer trim member. An inner trim member that is attached to the outer trim member and covers an opening of the outer trim member in a state where a gap is provided between the outer trim member and the outer trim member. dividing a mounting boss that is fixed by retaining state missing relative to the outer trim member is inserted into the insertion hole formed in the trim member, the vehicle front side of the mounting boss from the outer peripheral surface of the mounting boss , A longitudinal rib projecting into the vehicle vertical direction of the mounting boss from the outer peripheral surface of the mounting boss, and the transverse ribs projecting from the outer peripheral surface of the mounting boss to the vehicle rearward side of the mounting boss, which is configured to include a rib And a group.

  In the vehicle door trim mounting structure according to the first aspect, the outer trim member is mounted on the vehicle interior side of the door inner panel constituting the door inner plate of the side door. An inner trim member is attached to the outer trim member, and an opening formed in the outer trim member is covered with the inner trim member.

Here, the inner trim member protrudes outward in the vehicle width direction and has a curved shape formed along the vehicle longitudinal direction. A vertical wall is formed on the outer edge portion of the inner trim member, and the vertical wall abuts on the periphery of the opening formed in the outer trim member, so that the vehicle width is between the inner trim member and the outer trim member. A gap is provided in the direction.
Further, a mounting boss to be inserted into an insertion hole formed in the outer trim member is provided on the rear side of the inner trim member, and the mounting boss is fixed in a state of being prevented from being detached from the outer trim member. The A rib group projects from the outer peripheral surface of the mounting boss. The mounting boss is reinforced by the rib group.

  Thereby, an inner side trim member can be firmly attached to an outer side trim member via an attachment boss | hub. That is, the inner trim member is supported by the mounting boss and the rib group between the inner trim member and the inner trim member, and the inner trim member becomes difficult to bend. Therefore, the rigidity of the door trim during normal use is ensured.

By the way, this rib group specifically includes a vertical rib projecting from the outer peripheral surface of the mounting boss to the vehicle vertical direction of the mounting boss from the outer peripheral surface of the mounting boss, and the mounting boss. And a lateral rib projecting from the outer peripheral surface to the vehicle rear side of the mounting boss.
On the other hand, the inner trim member protrudes outward in the vehicle width direction and has a curved shape formed along the vehicle front-rear direction. Therefore, when the occupant touches the inner trim member, the inner trim member has a planar shape. Compared to the case, the pressure receiving area along the longitudinal direction of the vehicle is reduced. That is, the occupant touches the inner trim member with a small pressure receiving area along the vehicle vertical direction. Therefore, the load input when the occupant touches the inner trim member can be concentrated on the line along the vertical direction of the vehicle. For this reason, the inner trim member can ensure the required rigidity by the vertical ribs protruding from the outer peripheral surface of the mounting boss along the vertical direction.

  In the rib group, no rib is provided on at least the front side of the mounting boss. When a side collision occurs in the vehicle, the side of the occupant's upper body hits the inner trim member due to a secondary collision, and when a collision load is input to the inner trim member, the inner trim member deforms in the direction of bottoming out on the outer trim member. . For this reason, when the inner trim member is deformed in the direction of bottoming out on the outer trim member, the rear side of the inner trim member is deformed so as to fall to the front side of the inner trim member. Therefore, if the strength on the front side of the mounting boss is too high, the mounting boss and the surrounding area of the mounting boss (hereinafter referred to as “around the mounting boss”) are left uncrushed and the deformation of the inner trim member is hindered. Will be faster.

  In the present invention, since no rib is provided at least on the front side of the mounting boss, the rigidity around the mounting boss including the mounting boss is reduced as compared with the case where the rib is provided on the front side of the mounting boss. Is done. Thereby, the crush residue around the mounting boss is reduced, and the inner trim member can be sufficiently deformed. Thereby, what is called a bottom is suppressed and the reaction force which a passenger | crew receives will be reduced. Moreover, the stroke by which impact energy is absorbed by the inner trim member can be lengthened by reducing the crush residue.

  Here, the “vehicle longitudinal direction” includes not only a direction along the horizontal direction but also a case where the vehicle has a slight angle with respect to the horizontal direction. Further, the “vehicle vertical direction” includes not only a direction along the vertical direction but also a case where the vehicle has a slight angle with respect to the vertical direction.

  According to a second aspect of the present invention, there is provided a mounting structure for an automobile door trim according to the first aspect, wherein the vertical rib is formed along a ridge line provided between a vertical wall provided at an outer edge portion of the inner trim member. ing.

  When a collision load is input to the inner trim member by the secondary collision, the load is likely to concentrate on a ridge line provided between the inner trim member and the vertical wall provided at the outer edge portion. For this reason, in the structure of Claim 2, the rigidity at the time of normal use of an inner trim member further improves by forming the vertical rib which protrudes along the up-down direction from the outer peripheral surface of an attachment boss | hub along the said ridgeline. .

  As described above, the mounting structure for an automobile door trim according to the invention described in claim 1 has the excellent effect of ensuring the rigidity of the door trim and delaying the bottom timing of the door trim at the time of a side collision. Have.

  The automobile door trim mounting structure according to the second aspect of the invention has an excellent effect that the rigidity of the inner trim member during normal use can be secured.

(Operation / effect of the door trim mounting structure for automobiles)
As shown in FIG. 1, the door trim 16 includes an outer trim member 18 and an inner trim member 20, and the inner trim member 20 is attached to the outer trim member 18. In the present embodiment, the upper frame 32B, the rear frame 32C, and the lower frame 32D of the mounting seat surface 32 provided at the periphery of the opening 28 formed in the outer trim member 18 are locked in addition to the insertion holes 34. A hole 36 is provided.

  As shown in FIG. 3B, a locking piece 42 formed in the inner trim member 20 is inserted into the locking hole 36, and the locking piece 42 is elastically deformed and is locked. 50 is locked to the periphery of the locking hole 36. Accordingly, a pressing force that presses the inner trim member 20 toward the outer trim member 18 side (outward in the vehicle width direction) via the locking piece 42 acts, and the inner trim member 20 has the pressing force. The inner trim member 20 can ensure the necessary rigidity in this portion.

  When the inner trim member 20 is deformed to the outer trim member 18 side due to a secondary collision of the occupant with the door trim 16 at the time of a side collision of the automobile, the locking claws 50 of the locking pieces 42 are positioned around the locking holes 36. And the collision reaction force due to the secondary collision of the occupant in the side collision can be reduced, and the side collision performance regarding the secondary collision of the occupant can be ensured.

  On the other hand, as shown in FIGS. 3 (A) and 6 (A), mounting bosses 40 and 41 formed on the inner trim member 20 are inserted into the insertion holes 34, respectively, and the tips of the mounting bosses 40 and 41 are inserted. The inner trim member 20 is fixed to the outer trim member 18 in a state where the portion is crimped by heat (a state in which the portion is prevented from coming off). In this state, the gap 38 provided between the inner trim member 20 and the outer trim member 18 is filled with the mounting boss 40 and the rib 43, and the mounting boss 41 and the rib 44, respectively.

  For this reason, the inner trim member 20 is firmly attached to the outer trim member 18 via the attachment boss 40 and the rib 43, and the attachment boss 41 and the rib 44. That is, the inner trim member 20 and the outer trim member 18 are supported by the mounting boss 40 and the rib 43, the mounting boss 41 and the rib 44, and the inner trim member 20 is hardly bent. Therefore, the rigidity of the door trim 16 during normal use is ensured.

  Here, as shown in FIG. 5B, a rib 44 that protrudes from the outer peripheral surface of the mounting boss 41 is provided around the mounting boss 41, and the rib 44 is on the front side of the mounting boss 41. The vertical rib 44A provided on the upper side of the mounting boss 41, the vertical rib 44B provided on the lower side of the mounting boss 4, and the horizontal rib 44C provided on the rear side of the mounting boss 41 are configured. Has been. On the other hand, as shown in FIG. 4, the inner trim member 20 protrudes outward in the vehicle width direction and has a curved shape formed along the vehicle front-rear direction. Therefore, when the occupant touches the inner trim member 20, Compared to the case where the trim member 20 has a planar shape, the pressure receiving area along the vehicle longitudinal direction is reduced.

  That is, the occupant touches the inner trim member 20 with a small pressure receiving area along the vehicle vertical direction. Therefore, the load input when the occupant touches the inner trim member 20 can be concentrated on the line along the vehicle vertical direction. For this reason, a sense of rigidity can be obtained in the inner trim member 20 by the vertical ribs 44 </ b> A and 44 </ b> B projecting from the outer peripheral surface of the mounting boss 41 along the vertical direction.

  Further, as described above, in the rib 44 provided around the mounting boss 41, no rib is provided on at least the front side of the mounting boss 41. As shown in FIG. 6 (B), when the side collision of the vehicle, the side part of the upper body of the occupant F hits the inner trim member 20 due to a secondary collision, and when a collision load is input to the inner trim member 20, The inner trim member 20 is deformed in the direction of bottoming out the outer trim member 18. The inner trim member 20 is disposed inside the outer trim member 18 in order to close the opening 28 formed in the outer trim member 18.

  For this reason, when the inner trim member 20 is deformed in the direction of bottoming out the outer trim member 18, for example, FIGS. 7A and 7B show a comparative example of the present embodiment. In FIG. 7A, a cross-shaped rib 104 is provided around the mounting boss 102 on the rear side of the inner trim member 100. When the strength around the mounting boss 102 including the mounting boss 102 is too high, as shown in FIG. 7B, the ribs 104 are left uncrushed and the deformation of the inner trim member 20 is hindered. For this reason, timing with a bottom will be advanced.

  On the other hand, in this embodiment, as shown in FIG. 6A, the mounting boss 41 is not provided with a rib at least on the front side thereof. For this reason, compared with the case where a rib is provided on the front side of the mounting boss 41, the rigidity around the mounting boss 41 including the mounting boss 41 (hereinafter referred to as “around the mounting boss”) is reduced. As a result, as shown in FIG. 6B, the remaining crushing around the mounting boss is reduced, and the inner trim member 20 can be sufficiently deformed. Therefore, so-called bottoming is suppressed, and the reaction force received by the occupant is reduced. Moreover, the stroke by which impact energy is absorbed by the inner trim member 20 can be lengthened by reducing the crush residue.

  From the above, in the present embodiment, the rigidity of the door trim 16 can be secured and the bottom timing of the door trim 16 at the time of a side collision can be delayed. Thus, the deformation of the inner trim member 20 is not hindered, and the inner trim member 20 can be sufficiently deformed to reduce the collision reaction force due to the secondary collision of the occupant in the side collision. The effect of the locking piece 42 can be exhibited sufficiently.

  On the other hand, as shown in FIG. 2, the ribs 43 and 44 are provided along a ridge line P formed between the front wall 20 </ b> B and the vertical wall 20 </ b> A of the inner trim member 20. When a collision load is input to the inner trim member 20 due to a secondary collision, the load tends to concentrate on the ridgeline P. For this reason, the ribs 43 and 44 projecting from the outer peripheral surfaces of the mounting bosses 40 and 41 are formed along the ridgeline P, whereby the rigidity of the inner trim member 20 during normal use is further improved. In addition, sink marks may occur due to the formation of the ribs 43 and 44, but by forming the ribs 43 and 44 along the ridgeline P, the sink marks can be made inconspicuous.

  In the present embodiment, the rotary side door 12 is illustrated and described, but the present invention may be applied to a slide type side door.

(Supplement of this embodiment)
In the present embodiment, as shown in FIGS. 3A and 6A, the inner trim member 20 is fixed to the outer trim member 18 by thermally crimping the tip ends of the mounting bosses 40 and 41, respectively. However, it is only necessary that the inner trim member 20 can be attached to the outer trim member 18. For example, although not shown, a screw is screwed from the tip of the mounting boss, and the mounting boss is prevented from coming off by the head of the screw, so that the inner trim member 20 is fixed to the outer trim member 18. May be. Further, the fixing method may be different between the mounting boss 40 and the mounting boss 41.

  Further, in the present embodiment, as shown in FIG. 5B, the rib 44 provided around the mounting boss 41 excludes only the front side of the mounting boss 41, but the front side rib of the mounting boss 41. The lateral rib 44C on the rear side of the mounting boss 41 may be omitted. Further, although the rib 43 has a cross shape and the rib 44 has a T shape, the shapes of the ribs 43 and 44 are not limited to this. For example, the rib 43 may be composed of five ribs, and the shape of the rib may be changed depending on where the mounting bosses 41 and 43 are provided.
