Abstract

<P>PROBLEM TO BE SOLVED: To provide a mounting structure of a pillar trim free of the risk that a gap is generated between the bottom of a molded ceiling and the top of the pillar trim. <P>SOLUTION: As the top 9 of the pillar trim 8 is attached directly to a mounting seat part 5 formed from the bottom 3 of the molded ceiling 2, no gap will be generated between the bottom 3 of a molded ceiling 2 and the top 9 of the pillar trim 8. The distance from the engaging point of a projection 11 on a pillar 1 with an engaging hole 6 in the mounting seat part 5 to the termination of the top part 9 is short, and gap generation is unlikely even through a change with time. Because an extension part 7 abutting to the pillar 1 is formed from the bottom of the mounting seat part 5, the seat part 5 has a high rigidity, ensuring the mounting workmanship of the projection 11 in the engaging hole 6. The extension part 7 does not make deformation downward at the time of engaging the projection 11 with the hole 6 owing to formation of a projection 12 abutting from below to the extension part 7, and the engagement of the projection with the hole 6 can be performed still more certainly. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a pillar trim mounting structure in which a pillar trim is mounted from a vehicle interior side to a pillar whose upper end is covered by a lower end of a molded ceiling.

  The upper part of, for example, a center pillar of an automobile is covered with the lower end part of the molded ceiling. And the upper end part of the pillar trim is further superposed on the lower end part of the molded ceiling from the vehicle interior side without any gaps, so that the appearance is improved.

In the pillar trim, a clip seat surface portion is formed at a position where it does not overlap with the molded ceiling, and the pillar trim is attached to the pillar by a clip attached to the clip seat surface portion. The reason why the pillar trim is attached to the pillar is that the rigidity of the lower end of the molded ceiling is low and attachment by a clip is difficult (see, for example, Patent Document 1).
JP 2002-187572 A

  However, in such a conventional technique, the pillar trim itself is attached to the pillar by a clip, while the purpose is to polymerize the upper end of the pillar trim to the lower end of the molded ceiling. The pillar trim is an indirect attachment, and depending on how the pillar trim is attached, a gap may be formed between the lower end portion of the molded ceiling and the upper end portion of the pillar trim. In particular, in the upper end portion of the pillar trim, a gap is likely to be generated at a position away from the attachment point to the pillar by the clip.

  The present invention has been made paying attention to such a conventional technique, and provides a pillar trim mounting structure in which a gap is not formed between a lower end portion of a molded ceiling and an upper end portion of a pillar trim.

The invention according to claim 1 is a pillar trim mounting structure in which the upper end of the pillar trim is overlapped and mounted from the vehicle interior side to the lower end of the molded ceiling covering the upper part of the pillar,
The mounting seat surface portion is formed downward from the lower end portion of the molded ceiling, and an extension portion that contacts the pillar is formed from the lower end of the mounting seat surface portion, and is formed at the upper end portion of the pillar trim in the engagement hole formed in the mounting seat surface portion. The engaging protrusions engaged with each other are engaged.

  The invention described in claim 2 is characterized in that a protrusion is formed on the upper end portion of the pillar trim so as to come into contact with the extension portion from below.

  The invention described in claim 3 is characterized in that at least both side surfaces of the mounting seat surface portion are coupled to the extension portion.

  The invention according to claim 4 is a structure in which the engaging protrusion has a claw portion that engages with one of the upper edge or the lower edge of the engaging hole, and the upper edge of the engaging hole on the opposite side of the engaging protrusion. Alternatively, a restricting body that abuts the other of the lower edges is formed.

  According to the first aspect of the invention, since the upper end portion of the pillar trim is directly attached to the mounting seat surface portion formed from the lower end portion of the molded ceiling, there is a gap between the lower end portion of the molded ceiling and the upper end portion of the pillar trim. Does not occur. Further, the distance from the engagement point between the engagement protrusion and the engagement hole to the end of the upper end portion of the pillar trim is short, and a gap is hardly generated even with a change with time. Since the extension part that contacts the pillar is formed from the lower end of the mounting seat surface portion, the rigidity of the mounting seat surface portion is high, and the mounting of the engaging protrusion of the pillar to the engaging hole of the mounting seat surface portion can be performed reliably.

  According to the second aspect of the present invention, since the protruding portion that contacts the extension portion from the lower side is formed on the upper end portion of the pillar trim, the engaging protrusion of the pillar is engaged with the engaging hole of the mounting seat surface portion. In addition, the extension portion is not deformed downward, and the engagement of the engagement protrusion with the engagement hole can be performed more reliably.

  According to the third aspect of the present invention, since the side surface portions coupled to at least the extension portions are formed on both sides of the mounting seat surface portion, the mounting seat surface portion becomes three-dimensional and the rigidity is improved, and the engagement hole of the mounting seat surface portion is improved. It is possible to more reliably attach the engaging projection to the.

  According to the fourth aspect of the present invention, since the movement of the engagement protrusion in the engagement hole is restricted by the restricting body, the engagement force by the engagement protrusion is increased, and the lower end portion of the molded ceiling and the upper end portion of the pillar trim are It is possible to more reliably prevent the occurrence of a gap between them.

  For the purpose of providing a pillar trim mounting structure in which there is no gap between the lower end of the molded ceiling and the upper end of the pillar trim, the mounting seat surface is formed downward from the lower end of the molded ceiling, and the lower end of the mounting seat surface This is realized by forming an extension portion that abuts on the pillar and engaging the engagement protrusion formed on the upper end portion of the pillar trim with the engagement hole formed on the mounting seat surface portion. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 4 are views showing a first embodiment of the present invention. FIG. 1 is a side view of the vicinity of the upper end portion of the center pillar 1 as viewed from the vehicle interior side. The upper portion of the center pillar 1 is covered with a lower end portion 3 of the molded ceiling 2 as shown in FIG. A lower end portion 3 of the molded ceiling 2 is slightly inclined toward the center pillar 1 side, and a bent portion 4 is formed toward the center pillar 1 side from both ends of the front and rear sides of the lower end portion 3.

  A mounting seat surface portion 5 is formed at the center position of the center pillar 1 at the lower end portion 3 of the molded ceiling 2 so as to face downward. An engagement hole 6 is formed in the center of the mounting seat surface portion 5. From the end of the mounting seat surface portion 5, an extension portion 7 whose tip abuts against the center pillar 1 is formed. By forming the extension portion 7, the rigidity of the mounting seat surface portion 5 is improved.

  On the other hand, most of the center pillar 1 is covered with a pillar trim 8 attached from the vehicle interior side. The pillar trim 8 is attached to the center pillar 1 by known clip means except for the upper end portion 9 corresponding to the molded ceiling 2. The upper end portion 9 of the pillar trim 8 is superposed on the lower end portion 3 of the molded ceiling 2 to perform terminal processing of the lower end portion 3 of the molded ceiling 2.

  An engagement protrusion 11 having a downward claw portion 10 is formed on the upper end portion 9 of the pillar trim 8. Further, a rib 12 as a protrusion is formed slightly below the engagement protrusion 11. The rib 12 has an inclined edge corresponding to the extension portion 7 of the mounting seat surface portion 5.

  When such a pillar trim 8 is attached to the center pillar 1 from the vehicle interior side, the rib 12 comes into contact with the extension portion 7 and the engagement protrusion 11 engages with the engagement hole 6 of the attachment seat surface portion 5. The claw portion 10 of the engagement protrusion 11 engages with the lower edge of the engagement hole 6.

  By forming the extension portion 7 whose tip abuts against the center pillar 1, the rigidity of the mounting seat surface portion 5 itself is improved, but deformation of the extension portion 7 to the lower side is restricted by contact with the rib 12. Therefore, the rigidity of the mounting seat surface portion 5 is further increased, and the mounting seat surface portion 5 does not move to the center pillar 1 side even when the engaging projection 11 is engaged with the engaging hole 6. Engagement of the mating protrusion 11 can be performed reliably.

  According to this embodiment, since the upper end portion 9 of the pillar trim 8 is directly attached to the mounting seat surface portion 5 formed from the lower end portion 3 of the molded ceiling 2, the lower end portion 3 of the molded ceiling 2 and the upper end portion 9 of the pillar trim 8. There is no gap between them. The distance from the engagement point between the engagement protrusion 11 and the engagement hole 6 to the terminal of the upper end portion 9 of the pillar trim 8 is short, and a gap is hardly generated even with a change with time.

  5 to 8 are views showing a second embodiment of the present invention. In the molded ceiling 13 according to this embodiment, the side surface portions 14 coupled to the extension portion 7 and the bent portion 4 are formed on both sides of the mounting seat surface portion 5. In addition, ribs 16 as restricting bodies that protrude to the opposite side of the claw portion 10 are formed at both ends of the engagement protrusion 11 in the pillar trim 15. The rib 16 is formed with a narrow tip, and has a curved edge 17 that abuts on the upper edge of the engagement hole 6.

  According to this embodiment, since the side surface portion 14 is formed, the mounting seat surface portion 5 becomes three-dimensional and the rigidity is improved, and the attachment projection 11 is more reliably attached to the engagement hole 6 of the mounting seat surface portion 5. Can be done. Further, since the movement of the engagement protrusion 11 in the engagement hole 6 is regulated by the rib 16, the engagement force by the engagement protrusion 11 is increased, and the gap between the lower end portion 3 of the molded ceiling 13 and the upper end portion 9 of the pillar trim 15 is increased. The generation of the gap can be prevented more reliably.

  In the above embodiment, the center pillar 1 is taken as an example of the pillar, but the present invention is not limited to this, and the present invention can be applied to other pillars. Moreover, although the ribs 12 and 16 are taken as an example of the protrusions and the regulating bodies, other shapes may be used.
