Description

  The present invention relates to a vehicle interior member assembly structure in which a pair of interior members provided in a vehicle compartment is assembled.

  An interior member such as a trim or a garnish is provided in a vehicle compartment of an automobile or the like for the purpose of decoration, passenger protection, and the like. Generally, the interior member is made of a resin material by injection molding. The interior members cover a wide range of structures such as pillars, quarter panels, doors, instrument panels, center consoles, etc., mainly in the vehicle interior. In this case, in order to avoid increasing the size of the interior members, A wide range of the structure is divided and covered by a plurality of interior members. In many cases, when attaching a plurality of interior members to a structure, adjacent interior members are abutted. However, due to the floating that occurs at the abutting portion of the adjacent interior member, a gap is easily generated between the adjacent interior members, and the exterior of the vehicle, particularly the exterior of the vehicle interior, may be damaged by the clearance. Therefore, in order to prevent a gap from being generated between adjacent interior members, for example, the following assembly structure of an interior member for a vehicle is employed.

  In an example relating to the assembly structure of a vehicle interior member, as an interior member, an upper member and a lower member (pillar garnish upper and pillar garnish lower) of a pillar garnish that respectively cover an upper portion and a lower portion of the center pillar are provided. In this structure, the ribs extending in the abutting direction of the lower member and a direction perpendicular to the abutting direction (hereinafter, “ A rib extending in the “perpendicular direction” and a hook-shaped locking claw are formed, and the locking claw is attached to the center pillar. (For example, see Patent Document 1.)

  Moreover, in another example regarding the assembly structure of the interior member for a vehicle, as an interior member, an upper member and a lower member (pillar trim upper and pillar trim lower) of a pillar trim that respectively cover an upper portion and a lower portion of the center pillar are provided. These two members are assembled in the vertical direction of the vehicle. In such a structure, the butted portions of both members are arranged so as to overlap each other, and hook-shaped locking claws (locking portions) are placed on the butted portion of the lower member. Form a locking hole that penetrates the butted portion of the upper member corresponding to the locking claw, and hooks the locking claw of the lower member on the upper member while inserting the locking claw of the lower member into the locking hole of the upper member.

Mounting rigidity can be increased. As a result, it is possible to prevent the butted portions 3a and 4a of the upper trim 3 and the lower trim 4 from being lifted, thereby preventing the appearance of the vehicle from being damaged. In addition, since the structure that can prevent the butted portions 3a and 4a of the upper trim 3 and the lower trim 4 from being lifted as described above is simple, the butted portions 3a and 4a can be easily manufactured. The cost of 10 can be reduced. Therefore, the butted portions 3a and 4a of the upper trim 3 and the lower trim 4 can be easily manufactured while preventing the appearance of the vehicle, in particular, the appearance of the vehicle interior from being damaged. In particular, with respect to the upper trim 3 and the lower trim 4 of the quarter panel 2 that are easily visible to the passengers in the rear seat, the abutting portion 3a of the upper trim 3 and the lower trim 4 is prevented while preventing the appearance of the upper trim 3 and the lower trim 4 from being damaged. , 4a can be easily manufactured.

The rib 8 can be prevented from being visually recognized, and the appearance of the vehicle can be prevented from being damaged.

  In the assembly structure according to this embodiment, even when the rib 8 configured to be engageable with the groove 6 is formed on the inner peripheral surface 7f of the holding portion 7 in the abutting portion 4a of the lower trim 4, such a U-shape is formed. The shape inner peripheral surface 7f can be formed by the slide 13 of the mold 10 having a simple structure, and the butted portion 4a of the lower trim 4 can be manufactured by the mold 10 having a simple structure. Therefore, the abutting portions 3a and 4a of the upper trim 3 and the lower trim 4 can be easily manufactured while increasing the mounting rigidity of the upper trim 3 and the lower trim 4 by the engagement of the groove 6 and the rib 8.
