Description

  The present invention relates to a trim mounting structure such as a roof side trim member and a pillar trim member of an automobile.

In general, a trim that covers a vehicle interior side of a body panel of an automobile is attached by using a front pillar or a rear pillar portion that are integral with each other or a trim that is divided into two.
As a conventional technique, an end portion having a predetermined width is protruded from the position of the mounting portion on the vehicle body side, and the end portion is composed of a panel-like component that is overlapped and joined to an end portion on the other side. One of the rotation restricting pin and the rotation restricting hole fitted and engaged with the pin at a position shifted in the width direction of the end with respect to the straight line extending in the protruding direction of the end through the mounting portion. And the other end is provided at the other end, and the rotation locus of the rotation restricting pin tip centered on the straight line is set outside the rotation locus range of the rotation restricting hole. (See, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 07-108880 (refer to the claims section, detailed description section, and FIGS. 1 to 6)

In Patent Document 1, which is the conventional technique, the front pillar garnish and the rear pillar garnish are attached by positioning two members with a rotation regulating pin after positioning with a positioning pin.
However, although the fitting portion can be reliably fixed in a shape with a narrow width (a shallow cross section), if the width is wide (the cross section is deep), the wide end cannot be fixed. Therefore, the fitting force of the mating portion varies, and a gap may be generated between the members, resulting in poor appearance.
Further, because of the fitting by insertion, the lifting direction cannot be regulated, and a gap in the surface difference direction is generated. Furthermore, there is a concern that the attachment terminal portion may be lifted due to thermal contraction of the two members due to long-term use of the vehicle.
Further, in the conventional method for attaching the roof side trim member, there is a work space restriction on the upper part and the lower part during the assembling work, and the work of fitting the pillar from the bottom to the top is impossible.

A first invention of the present invention capable of solving the above-described problems is a fitting structure for a roof side trim member as described in claim 1, and is as follows.
A fitting structure of a roof side trim member disposed at a ceiling side corner in a vehicle width direction of a passenger compartment and a pillar trim member attached to one end of the roof side trim member, wherein the roof side trim member is a roof A side trim main body and a locking portion having a U-shaped cross section are extended at one end of the roof side trim main body, and the pillar trim member is a pair of locking the pillar trim main body and the locking portion of the roof side trim member. A locking piece is provided, and the one locking piece is rotated around the rotation center so that the other locking piece is locked to the locking portion of the roof side trim member.

A second invention of the present invention capable of solving the above-described problems is a fitting structure for a roof side trim member as described in claim 2, and is as follows.
In addition to the invention described in claim 1, the pillar trim member has a configuration in which a head lining locking piece for locking a terminal of a head lining that covers the ceiling of the passenger compartment is provided on the one locking piece side.

Since the roof side trim member fitting structure according to the present invention has the configuration as described above, the following effects can be obtained.
(1) The pillar trim member and the roof side trim member can be reliably fixed without a gap by rotating around one of the locking pieces of the pillar trim member.
(2) In the invention described in claim 2, the headlining can be attached simultaneously with the attaching operation of the roof side trim member and the pillar trim member.
(3) Regardless of the width (whether narrow or wide) of the cross section of the roof side trim, it is possible to reliably prevent the pillar trim from hanging down.
(4) Each member with a different assembly direction can be assembled successfully.
(5) Since the fitting part can be made into an integral structure, there is no need for a separate clip or the like at the time of attachment, and the cost is reduced.
(6) Since the roof side trim and the pillar trim can be formed separately, the modeling can be made finer, the design of the vehicle interior can be improved, and the finish when finished is beautiful.
