Japanese Patent Laid-Open No. 2003-081021

  In the mounting structure described above, the joint portion for mounting the interior member is sufficiently separated from the vehicle body panel, so that a space sufficient for caulking and screw fastening can be secured, and even after the interior member is mounted. If a certain space can be ensured between the vehicle body panel and the vehicle body panel, it can be used without any trouble. However, in a location where the joint location is close to the vehicle body panel, a sufficient space is not ensured on the back surface side (vehicle body panel side) of the interior member, which makes it difficult to fix by caulking or screw fastening. Even if attachment by fastening, etc. is possible, if a certain clearance is not secured between the fastening part and the vehicle body panel, the fastening part and the vehicle body panel will collide with each other due to vibration during vehicle traveling, etc. Will occur.

  Therefore, as a mounting structure that can be used when a sufficient space cannot be secured between the joint portion for mounting the interior member and the vehicle body panel, a simple fixing structure such as a hooking claw can be considered. When a soft material such as a skin material is attached or wound on the mounting member side (interior material side), the nail hooked by the repulsive force of the skin material itself is likely to come off and stable. Installation becomes difficult. Therefore, if the skin material is shortened so that the skin material does not get caught in the end portion of the mounted member (where the claw is hooked), there is a concern that the skin material may turn over and peel off easily.

  The present invention has been made in view of the above circumstances, and even if a skin material is wound around the interior material in a location where a sufficient space cannot be secured between the joint location for mounting the interior member and the vehicle body panel. An object of the present invention is to provide a vehicle interior member mounting structure that can be stably mounted.

  In order to solve the above-mentioned problems, the present invention provides a vehicle interior member mounting structure for attaching an interior member to an interior material opposed to a vehicle panel.

The interior member is inserted into the opening while the locking portion winds around the extra length portion, so that the locking portion is locked to the opening, and the interior material It is attached.

  According to such a vehicle interior member mounting structure, even when an interior member is attached to an interior material having a skin material, even if a sufficient space cannot be secured between these mounting locations and the vehicle panel, Space interior members can be attached. In other words, when attaching the interior member, only the locking portion provided on the interior member itself is attached to the interior material, so no separate member such as a mounting boss is required, and the tip of the mounting boss is crimped or fastened. A space to be fastened is not required, and the interior member can be mounted even at a location where a sufficient space cannot be secured between the mounting location and the vehicle panel. In addition, the nail return is not hooked onto the surface of the skin material laminated on the interior material using something like a locking claw, and the locking portion of the interior member has an extra length at the end of the skin material. Since it is inserted into the opening of the interior material while being wound and the excess length portion is retained, stable attachment is possible without being affected by the repulsive force of the skin material itself. Furthermore, it is not necessary to previously bond the extra length portion of the skin material end to the back surface of the interior material.

  In the mounting structure for an interior member for a vehicle, the locking portion has the extra length portion opened to the opening so that the extra length portion is held between the latching portion and an opening edge of the opening portion. It can be guided along the edge.
