On the vehicle exterior side surface of the vehicle door trim of Patent Document 1 listed below, an impact absorber (impact that can absorb a shock at the time of a side collision is provided on the rear side of the door pocket (corresponding to the pocket opening of Patent Document 1). Absorption pad) is arranged.

JP 2000-177517 A

  In the said structure, since the shock absorber is arrange | positioned at the vehicle back of a door pocket, a door pocket cannot be extended to the vehicle back. That is, since the length of the door pocket in the vehicle front-rear direction is restricted, there is a problem that it is difficult to secure the size of the accommodation space of the door pocket.

  The present invention has been completed based on the above circumstances, and an object of the present invention is to provide a vehicle door trim capable of increasing the accommodation space of a door pocket while ensuring shock absorbing performance. .

  In order to solve the above-described problems, the present invention provides a vehicle door trim that is attached to a vehicle door panel from the vehicle interior side, the trim board, and a door pocket that is attached to the trim board from the outside of the vehicle compartment. The door pocket includes a bottom wall portion that constitutes a bottom portion of the door pocket, a facing wall portion that is disposed to face a vehicle exterior side surface of the trim board, and a trim from a peripheral end portion of the facing wall portion. A door pocket standing wall portion that rises toward the board, wherein the bottom wall portion, the facing wall portion, the door pocket standing wall portion, and the trim board constitute at least a housing space for the door pocket, and the door The pocket extends from the end of the door pocket standing wall on the trim board side along the outer side surface of the trim board. A first extending wall portion that extends, and a second extending wall portion that extends from an extending end of the first extending wall portion toward the vehicle door panel. An end surface of the installation wall portion on the vehicle door panel side is arranged at a position closer to the vehicle door panel than a surface of the opposing wall portion on the vehicle door panel side.

Therefore, in the present invention, a connecting rib that connects the second extending wall portion and the rear wall portion is provided. Thereby, a deformation | transformation of a 2nd extending wall part can be suppressed to some extent, and an impact can be absorbed more effectively. Further, if such a connecting rib is provided, the second extending wall portion can be easily deformed by adjusting the connecting rib configuration (for example, the length and shape of the rib) at the time of designing. Therefore, the shock absorbing performance can be easily adjusted.

Further, the second extending wall portion includes a wall main body portion extending outward from the first extending wall portion, and a vehicle interior.
A bent portion that extends from an extended end of the wall main body and is bent with respect to the wall main body so as to be opposed to the vehicle door panel, and is bent from the wall main body. And a standing rib connected to the portion.

  By having such a standing rib, the deformation of the wall main body and the bent portion can be suppressed to some extent, and the impact can be absorbed more effectively. In addition, it is possible to easily adjust the easiness of deformation of the second extending wall portion by adjusting the configuration of the standing rib (for example, the length and shape of the rib) at the time of design. Can be adjusted easily.

  Moreover, the 1st extending wall part shall be provided with the attaching part which can be attached to the said trim board.

  By attaching the first extending wall portion to the trim board, the first extending wall portion, and thus the second extending wall portion extending from the first extending wall portion, is more reliably positioned with respect to the trim board. be able to. Thereby, the situation where the position of the 2nd extension wall part shifts at the time of a side collision can be controlled, and an impact can be absorbed more certainly at the predetermined position in a trim board.

  The trim board includes a trim main body portion disposed opposite to the vehicle door panel, and a trim standing wall portion rising from a peripheral end portion of the trim main body portion toward the outside of the passenger compartment. The wall portion may be disposed to face the trim standing wall portion.

  If the second extending wall portion is easily deformed at the time of a side collision, there is a concern that the impact at the time of the side collision cannot be sufficiently absorbed and the shock absorbing performance is deteriorated. Therefore, in the present invention, the second extending wall portion is arranged to face the trim standing wall portion. Thereby, when the second extending wall portion is deformed to the trim standing wall portion side, the deformation of the second extending wall portion can be suppressed to some extent by coming into contact with the trim standing wall portion. The impact can be absorbed more effectively.

The trim board includes a trim main body disposed opposite to the vehicle door panel;
The trim main body portion has a trim standing wall portion erected from the peripheral end portion toward the vehicle compartment outer side, the wall portion main body portion is arranged to face the trim standing wall portion, and the standing rib is the wall It can be erected from the main body part toward the trim standing wall part.

  If the second extending wall portion is easily deformed at the time of a side collision, there is a concern that the impact at the time of the side collision cannot be sufficiently absorbed and the shock absorbing performance is deteriorated. Therefore, in the present invention, the standing rib is erected toward the trim standing wall portion. With such a configuration, when the second extending wall portion is deformed to the trim standing wall portion side at the time of a side collision, the standing rib comes into contact with the standing wall portion of the trim board. Thereby, a deformation | transformation of a 2nd extending wall part can be suppressed to some extent, and the impact at the time of a side collision can be absorbed more effectively. Further, if such a standing rib is configured to contact the trim standing wall portion, for example, by adjusting the height of the standing rib, the surface of the second extending wall portion directly contacts the trim standing wall portion. Compared with the structure which contacts, it becomes easier to contact.

  Moreover, the said 2nd extending wall part shall be distribute | arranged to the location facing the waist | hip | lumbar part of the seated passenger | crew.

  With such a configuration, it is possible to protect the occupant's waist during a side collision.

  Next, the effect of this embodiment will be described. The door trim 10 of this embodiment is a door trim 10 that is attached to the door inner panel 11 from the vehicle interior side, and includes a trim board 12 and a door pocket 30 that is attached to the trim board 12 from the outside of the vehicle interior. The door pocket 30 is trimmed from the bottom wall portion 31 constituting the bottom portion of the door pocket 30, the opposing wall portion 33 arranged to face the outer side surface of the trim board 12, and the peripheral end portion of the opposing wall portion 33. A rear wall portion 37 rising toward the board 12, and the bottom wall portion 31, the opposing wall portion 33, the rear wall portion 37, and the trim board 12 constitute at least the accommodation space S1 of the door pocket 30, The door pocket 30 extends from the end of the rear wall portion 37 on the trim board 12 side along the passenger compartment outer surface 12A1 of the trim board 12. A first extending wall portion 50 and a second extending wall portion 51 extending from the extending end of the first extending wall portion 50 toward the door inner panel 11. An end surface 51A on the outer side of the casing 51 in the wall 51 is arranged closer to the door inner panel 11 than a surface 33A on the outer side of the casing in the opposing wall 33.

  With such a configuration, when the door inner panel 11 disposed outside the vehicle interior of the door trim 10 (and eventually the door pocket 30) is displaced toward the vehicle interior during a side collision, the door inner panel 11 is The second extending wall portion 51 is in contact with the end surface 51A on the outer side of the passenger compartment. As a result, when the end surface 51 </ b> A outside the passenger compartment in the second extending wall portion 51 is pressed by the door inner panel 11, the second extending wall portion 51 is deformed. Thereby, the impact at the time of a side collision can be absorbed.

  More specifically, in the present embodiment, the rear wall portion 37, the first extending wall portion 50, and the second extending wall portion 51 are arranged in a substantially U-shape that opens to the outside of the passenger compartment. Therefore, at the time of a side collision, the second extending wall portion 51 is deformed in the direction in which the opening is opened. That is, the second extending wall portion 51 is deformed so as to tilt toward the vehicle rear side (the trim standing wall portion 12B side) with respect to the first extending wall portion 50, as indicated by a two-dot chain line in FIG.

  That is, in the present embodiment, an impact absorbing function can be added to the door pocket 30, and the impact absorbing material conventionally provided in the door trim 10 can be eliminated. For this reason, the door pocket 30 can be extended to the vehicle rear part in the door trim 10 (the place where the shock absorber is conventionally provided), and the accommodation space can be further increased.

  Here, the end surface 51A of the second extending wall portion 51 outside the passenger compartment is disposed closer to the door inner panel 11 than the surface 33A of the opposing wall portion 33 outside the passenger compartment. For this reason, at the time of a side collision, the door inner panel 11 comes into contact with the second extending wall portion 51 before contacting the opposing wall portion 33. Thereby, it is possible to absorb the impact at a relatively early stage at the time of a side collision, and it is possible to further improve the impact absorbing performance. Furthermore, in the present embodiment, by appropriately changing the configuration of the second extending wall portion 51 at the design stage, it is possible to control the deformation of the second extending wall portion 51 at the time of a side collision and absorb the shock. It is also possible to adjust the performance.

  Further, a connecting rib 53 that connects the second extending wall portion 51 and the rear wall portion 37 is provided.

  If the second extending wall portion 51 is easily deformed at the time of a side collision, there is a concern that the impact at the time of the side collision cannot be sufficiently absorbed and the shock absorbing performance is deteriorated. Therefore, in the present embodiment, the connection rib 53 that connects the second extending wall portion 51 and the rear wall portion 37 is provided. Thereby, the deformation | transformation of the 2nd extending wall part 51 can be suppressed to some extent, and an impact can be absorbed more effectively. In addition, when the 2nd extending wall part 51 deform | transforms into the trim standing wall part 12B side, each connection rib 53 deform | transforms in the form extended in the vehicle front-back direction.

  Further, if such a structure is provided, the second extending wall portion 51 can be easily deformed by adjusting the length of the connecting rib 53 in the vehicle interior / exterior direction at the time of design. Since it can be adjusted, the impact absorption performance can be easily adjusted. That is, by shortening the connecting rib 53, the rigidity of the second extending wall portion 51 is reduced, and the second extending wall portion 51 is easily deformed.

  For example, when the door pocket 30 is molded by an injection mold, the length of the connecting rib 53 is formed to be large, and after the molding, the length is adjusted by cutting the connecting rib 53, etc. The optimum length of the connecting rib 53 can be easily determined by adjusting the ease with which the extending wall portion 51 is deformed.

  Further, the second extending wall portion 51 extends from the first extending wall portion 50 to the outside of the passenger compartment, and extends from the extending end of the wall portion main body portion 52A, and is disposed opposite to the door inner panel 11. The bent portion 52B is bent with respect to the wall main body portion 52A, and the standing rib 55 is erected from the wall main body portion 52A and connected to the bent portion 52B.

  By having such a standing rib 55, the deformation of the wall main body 52A and the bent portion 52B can be suppressed to some extent, and the impact at the time of a side collision can be absorbed more effectively. Further, since the ease of deformation of the second extending wall portion 51 can be easily adjusted by adjusting the configuration (for example, length and shape) of the standing rib 55 at the time of design, the shock absorbing performance can be improved. It can be adjusted easily.

  The first extending wall portion 50 is provided with an attachment hole 50E that can be attached to the trim board 12.

  By attaching the first extending wall portion 50 to the trim board 12, the first extending wall portion 50, and thus the second extending wall portion 51 extending from the first extending wall portion 50, can be more reliably trimmed. 12 can be positioned. Thereby, the situation where the position of the 2nd extending wall part 51 shift | deviates at the time of a side collision can be suppressed, and an impact can be more reliably absorbed in the predetermined position in the trim board 12. FIG.

  The trim board 12 includes a trim main body portion 12A that is disposed to face the door inner panel 11, and a trim standing wall portion 12B that rises from the peripheral end portion of the trim main body portion 12A toward the outside of the passenger compartment. The installation wall portion 51 is disposed to face the trim standing wall portion 12B.

  If the second extending wall portion 51 is easily deformed at the time of a side collision, there is a concern that the impact at the time of the side collision cannot be sufficiently absorbed and the shock absorbing performance is deteriorated. Therefore, in the present embodiment, the second extending wall portion 51 is arranged to face the trim standing wall portion 12B. Accordingly, when the second extending wall portion 51 (standing rib 55) is deformed toward the trim standing wall portion 12B, the deformation of the second extending wall portion is suppressed to some extent by contacting the trim standing wall portion 12B. It is possible to absorb the impact at the time of a side collision more effectively. In FIG. 6, the second extending wall portion 51 in contact with the trim standing wall portion 12 </ b> B is illustrated by a two-dot chain line.

  Further, the standing rib 55 can be erected from the wall main body 52A toward the trim standing wall 12B.

  With such a configuration, when the second extending wall portion 51 is deformed to the trim standing wall portion 12B side at the time of a side collision, the standing rib 55 contacts the trim standing wall portion 12B. Thereby, the deformation | transformation of the 2nd extending wall part 51 can be suppressed to some extent, and the impact at the time of a side collision can be absorbed more effectively. In FIG. 6, reference numeral 55 </ b> A is attached to the standing rib that is in contact with the trim standing wall portion 12 </ b> B, and is shown by a two-dot chain line.

  In addition, when such a standing rib 55 is configured to abut on the trim standing wall portion 12B, for example, the height of the standing rib 55 is adjusted so that the surface of the second extending wall portion 51 is trimmed. Compared to the configuration in which the portion 12B is in direct contact, it is easier to contact.

  Moreover, the 2nd extension wall part 51 is distribute | arranged to the location facing the waist | hip part 20B of the passenger | crew 20 who seated.

  With such a configuration, the waist 20B of the occupant 20 can be protected during a side collision.

  Further, in the present embodiment, the partition wall portion 35 has a longitudinal shape and is interposed between the opposing wall portion 33 and the trim board 12, and one end portion on the vehicle front side in the longitudinal direction is located on the other side of the vehicle rear side. It extends so as to be arranged at a high position with respect to the end.

  With such a configuration, when the vehicle collides, the partition wall portion 35 interposed between the facing wall portion 33 and the trim board 12 is deformed (for example, buckled), thereby acting on the occupant 20. Can absorb shocks. The partition wall portion 35 is disposed at a location facing the leg portion 20A (particularly the thigh) of the seated occupant 20, and can protect the leg portion 20A of the occupant 20.

  In the conventional configuration, when the shock absorber is arranged on the trim board 12 so as to protect the passenger's legs (particularly, the thigh) in addition to the passenger's waist, the shock absorber has a certain size. Is required. As a result, the storage space of the door pocket is reduced by the amount of the shock absorber. That is, the expansion of the shock absorption range leads to a reduction in the accommodation space of the door pocket as it is.

  On the other hand, in this embodiment, since the shock absorption performance is added to the door pocket 30, it is not necessary to provide a separate shock absorber. For this reason, the accommodation space of a door pocket can be enlarged only by the part which there is no separate shock absorber.

  This will be described in detail. Conventionally, in the door trim 10, shock absorbers are provided at the lower part and the rear part (location corresponding to the vehicle rear space S <b> 3 in the present embodiment). According to this embodiment, since the shock absorbing function is added to the door pocket 30, it is not necessary to provide a shock absorber. For this reason, the door pocket 30 can be extended to the vehicle rear part in the door trim 10 (the place where the shock absorber is conventionally provided), and the accommodation space S1 can be further increased. That is, in this embodiment, it is possible to enlarge the accommodation space S1 by the vehicle rear space S3.

  The vehicle rear space S3 is opened forward of the vehicle, and the partition wall portion 35 extends along the vehicle front-rear direction and protrudes from the bottom wall portion 31 so as to rise upward as it goes toward the vehicle front. .

  Thereby, the partition wall part 35 can be distribute | arranged along the extension direction of 20 A of leg parts of the passenger | crew 20, and the leg part 20A of the passenger | crew 20 extended in the vehicle front-back direction can be protected effectively. Further, by arranging the partition wall portion 35 along the vehicle front-rear direction, the upper surface 35A of the partition wall portion 35 can be used as the bottom surface of the vehicle rear space S3. Then, if the partition wall portion 35 is configured to rise and incline toward the front of the vehicle, when the stored item is placed on the upper surface 35A of the partition wall portion 35, the stored item from the vehicle rear space S3 opened to the front of the vehicle. Can be prevented from jumping out.

  The partition wall portion 35 is erected from the opposing wall portion 33 toward the trim board 12 (the trim main body portion 12A), and the partition wall portion 35 is provided with an attachment surface portion 36 that can be attached to the trim board 12. It has been.

  Thereby, the partition wall part 35 can be reliably fixed to the trim board 12. Thereby, at the time of a side collision, as a result of suppressing the situation where the partition wall part 35 tilts with respect to the opposing wall part 33, it can buckle reliably and can make shock absorption performance higher.

  Moreover, the vehicle rear space S3 is comprised, and the rear wall part 37 extended toward upper direction from the edge part of the vehicle rear side in the partition wall part 35 is provided.

  When the door pocket 30 is arranged so that the partition wall portion 35 is arranged along the leg portion 20A of the occupant 20, the rear wall portion 37 is arranged near the lumbar portion of the occupant 20 and along the height direction of the lumbar portion. The Rukoto. Thereby, the impact which acts on the waist | hip | lumbar part of the passenger | crew 20 can be absorbed by the rear wall part 37 deform | transforming (for example, buckling) at the time of a side collision.

  Moreover, the vehicle rear space S3 is comprised and the upper wall part 39 extended along the vehicle front-back direction from the upper end in the rear wall part 37 is provided.

  When the door pocket 30 is disposed such that the partition wall portion 35 is disposed along the leg portion 20A of the occupant 20, the upper wall portion 39 is also disposed along the leg portion 20A of the occupant 20. Thereby, at the time of a side collision, as a result of the upper wall portion 39 being deformed (for example, buckling), the occupant's leg portion can be more reliably protected together with the partition wall portion 35.

  Thus, in this embodiment, the passenger | crew 20 can be protected because the partition wall part 35, the rear wall part 37, and the upper wall part 39 deform | transform at the time of a side collision. Thus, an impact can be absorbed by the wall part which comprises vehicle back space S3.

  Specifically, the waist 20B of the seated occupant 20 can be protected by the rear wall portion 37 and the upper wall portion 39, and the leg portion 20A of the occupant 20 is protected by the partition wall portion 35 at the time of a vehicle side collision. can do. As a result, the occupant 20 can be protected from the waist 20B to the leg 20A, and the shock absorption range can be expanded.

  When the occupant 20 is seated, in the front view of the door trim 10, the pubic bone of the occupant 20 (illustrated as a point P1 in FIG. ) Is placed. As a result, in the vicinity of the pubis where the sensitivity to the impact is relatively high in the human body, a load is not directly received from each of the wall portions 35, 37, and 39 in a side collision, and the occupant can be more reliably protected. .

  In the present embodiment, the wall thickness (partition wall portion 35, rear wall portion 37, second extending wall portion 51, etc.) related to shock absorption at the time of a side collision is the same as the other wall portions of the door pocket 30. It is set larger than the plate thickness of (for example, the opposing wall portion 33). Thereby, the situation which each wall part 35, 37, 51 deform | transforms easily in the initial stage of a side collision can be suppressed, and the impact at the time of a side collision can fully be absorbed.
