[Prior art]
Generally, interior materials are laid on the interior of a car to protect and decorate the interior. This type of interior material is a headliner interior material or carpet interior material, which is laid after molding a thin base material (made of thermoplastic resin, fiber containing a binder, etc.) into a shape that fits the laying position. ing. Often a decorative skin is applied to the surface of the substrate.
This type of interior material is attached to the vehicle body by attaching an attachment to the back surface of the base material (the surface facing the vehicle body of the automobile) and engaging the attachment with the vehicle body side engagement device. Alternatively, a through opening is formed in the base material, and mounting clips are inserted from the surface side of the interior material and are attached to the vehicle body mounting hole.
Other interior accessories are often attached to this type of interior material. For example, an assist grip and a room lamp lens are attached as accessories to the headliner interior material. (Often the attachment of accessories to the interior material substrate also serves as the attachment of the interior material to the vehicle body.)
Conventionally, this type of accessory is attached by a fastener such as a screw.
FIG. 3 shows a state in which the room lamp lens 50 (accessory) is attached to the headliner interior material base 51 as an example of a general attachment structure of a conventional accessory.
In this example, the accessory 50 is formed by injection molding of a thermoplastic resin, and a plurality of mounting ribs 52 are erected and formed on the back surface facing the interior material base material. On the other hand, an opening 53 corresponding to the attachment rib is formed at the accessory attachment position of the interior material base 51.
The procedure for attaching the accessory to the interior material base material is that the accessory mounting rib 52 is aligned and held in the opening 53 of the interior material base material, and then the screw screw 56 is passed through the opening 53 from the back side of the interior material base material. By screwing and engaging with the attachment rib 52 of the accessory. In this type of screwing, in order to prevent the base material from being bent, a reinforcing plate 54 is often disposed on the back surface of the base material and fastened together.
The problem with the conventional accessory mounting structure is that the process of aligning the opening positions of the accessory and the interior material base material and screwing it from the back side of the interior material base material is complicated and cannot be performed with one touch. It was.
