Interior material
A door lining serving as an interior material comprises a door center portion. The door center portion is provided with: a door center base material; a door center pad supported by the door center base material and configured to be elastically deformable; a door center surface skin material covering the door center pad; and a sewed portion formed by sewing the door center pad and the door center surface skin material together by a sewing thread. In the door center pad, a thick section and a thin section are formed, and the sewed portion is provided in the thin section.
1. An interior member comprising:
a pad including a thin-walled portion and a thick-walled portion, the pad being elastically deformable;
a skin member that covers the pad;
a sewn region produced by sewing the pad and the skin member to each other with a sewing thread; and
a base that supports the pad thereon,
wherein:
the sewn region is disposed on the thin-walled portion of the pad,
the thin-walled portion is made thinner than the thick-walled portion so as to reduce a reaction force applied from the pad to the sewing thread, and
the base integrally includes a ledge configured to push a portion of the sewn region, that is positioned on a side of the pad, toward the skin member of the sewn region.
2. The interior member according to claim 1 , wherein the thin-walled portion is formed by bending.
3. The interior member according to claim 1 , wherein the ledge has a corner; and
the sewing thread is held in contact with a portion of the ledge that is different from the corner.
4. The interior member according to claim 1 , wherein the ledge is of an arc-like cross-sectional shape.
5. The interior member according to claim 1 , wherein the base further includes a flat portion contiguous to the ledge; and
the thick-walled portion is disposed on the flat portion, and the thin-walled portion is disposed on the ledge.
6. The interior member according to claim 1 , wherein an area of the thin-walled portion that corresponds to the sewn region is thinner than an area of the thin-walled portion that does not correspond to the sewn region.
7. The interior member according to claim 1 , wherein the sewn region includes:
a thin-walled sewn region produced by sewing the skin member and the thin-walled portion to each other with the sewing thread; and
a thick-walled sewn region produced by sewing the skin member and the thick-walled portion to each other with the sewing thread, the thin-walled sewn region and the thick-walled sewn region being integral with each other.
8. The interior member according to claim 1 , wherein the thin-walled portion is wider than a diameter of the sewing thread.
9. The interior member according to claim 1 , wherein the interior member is mounted on a vehicle.
10. The interior member according to claim 1 , wherein the thin-walled portion is made of polypropylene foam.
11. The interior member according to claim 4 , wherein the sewing thread is positioned on a crest of the ledge.
