  By the way, in the vehicle interior structure using interior panels and outfitting panels made of extruded shapes as described above, the seam (between the ends of each member) during mounting (construction) on the vehicle body, depending on the component accuracy and assembly accuracy. In some cases, a level difference or “mistake” occurs.

  In addition, this level difference and misunderstanding can cause defects (deterioration of continuity) as the exterior of the interior material. In order to improve the appearance (finished state) of this part, during installation (construction) to the vehicle body However, there is a problem that adjustment work by the operator (“current car alignment”) is required, and this adjustment takes time, and the finished state depends on the skill and experience of the operator.

  The present invention has been made in order to cope with the above-described problems. Even when adjustment to the vehicle body is not performed by the operator, a continuous appearance of a good-looking interior material without a step between seams between the members is provided. An object of the present invention is to provide a mounting structure for a vehicle interior material capable of forming a surface.

  In order to achieve the above object, according to the first aspect of the present invention, there is provided an extruded member having a plurality of reinforcing ribs parallel to the longitudinal direction formed on the back surface so that the longitudinal ends thereof are adjacent to each other. Are arranged side by side in the longitudinal direction of the vehicle, and each of these extrusion-molded members is attached to a base provided on the side of the vehicle body, thereby forming an interior surface of the cabin where a uniform surface appearance continues at a predetermined position of the vehicle body. A vehicular interior material mounting structure, wherein the reinforcing rib has a substantially C-shaped or O-shaped tapping hole shape in which a part of a cross-sectional shape viewed from the longitudinal direction of the vehicle can pass a screw or a bolt. The extruded member has a shape substantially along the widthwise shape of the back surface of the extruded member at both ends in the longitudinal direction of the reinforcing rib, and the design of the extruded member. A forcing plate having a hole provided at a position corresponding to each tapping hole shape in the reference cross-sectional shape of the base plate is fixed in advance using screws or bolts, and attached to a base provided on the vehicle body side. It is characterized by being.

  The present invention provides an interior material for a vehicle that forms a continuous surface having a sense of unity at a predetermined position by attaching a plurality of extruded shapes having reinforcing ribs on the back surface side by side to a predetermined position of the vehicle. In the mounting structure, a "forced plate" that corrects variations in the cross-sectional shape of the extruded shape to the shape as originally designed is attached to the side of the end of the extruded shape. In addition to eliminating the adjustment work (matching the current vehicle), it is intended to save labor and improve the appearance of this installation work.

  That is, according to the first aspect of the present invention, the reinforcing rib provided on the back surface of the extrusion-molded member is substantially C in which a part of the cross-sectional shape viewed from the vehicle longitudinal direction can be inserted with a screw or a bolt. In the shape of a "tapping hole" or a substantially O-shape, and at the position corresponding to each of the above tapping hole shapes in the reference (standard) cross-sectional shape at the time of designing the extruded member, By aligning the “holes” of the forced plate provided with “holes” and attaching the forced plates to both ends in the longitudinal direction of the reinforcing rib using screws, bolts, etc. Alternatively, it is possible to easily and accurately correct the cross-sectional shape variation (longitudinal variation) that occurs during storage.

  Further, the extrusion-molded member with a forced plate does not cause a step or a mistake in the joint between the members even when attached to the vehicle body without adjustment work by the operator. Therefore, the mounting structure for a vehicle interior material according to the present invention can shorten the work time required for the mounting, and can construct a uniformly finished interior material surface that is not affected by the skill and experience of the operator. it can.

  The material constituting the compulsory plate to be mounted on the extruded member is not particularly limited, but the shape of the extruded member is “forcedly” deformed. A member having higher rigidity is required. In addition, as a material constituting the compulsory plate, for example, a metal plate, a stainless steel plate, and the like are preferable. Can be applied with a high-precision processing method using a laser, a water jet, or the like.

  Here, it is preferable to employ a configuration in which notches are provided in both end portions of the reinforcing rib having the tapping hole shape, and the reinforcing ribs have a shape having a length in the longitudinal direction shorter than the surface of the extruded member. (Claim 2).

  This configuration takes into account the thickness of the forced plate attached to both ends of the extrusion-molded member, and by providing notches corresponding to the thickness of the forced plate at both ends of the reinforcing rib, the forced plate Even in the state of mounting, these forcing plates do not protrude in the longitudinal direction from the end of the extruded member. Therefore, like the conventional structure, it is not necessary to open an extra gap between adjacent members, and a continuous surface of the interior material having a good appearance can be constructed.

  As described above, according to the mounting structure for a vehicle interior material of the present invention, it is possible to quickly and accurately perform the appearance without a step between the members without performing adjustment work by an operator at the time of mounting on the vehicle body. A continuous surface of good interior material can be constructed.
