Abstract

An interior member includes a first skin material, a second skin material, and transducers. The first skin material includes a first exposed part exposed to a cabin interior, and a first embedded part embedded on a cabin exterior side from the first exposed part. The second skin material includes a second exposed part exposed to the cabin interior and adjacent to the first exposed part, and a second embedded part embedded on the cabin exterior side from the second exposed part and joined to the first embedded part. The transducers each include a main body arranged directly back of the first exposed part, and a wiring part disposed directly back of at least the first embedded part and electrically connected to the main body. An end of each wiring part is disposed on the cabin exterior side of the first embedded part.

First claim

The invention claimed is:

1. An interior member comprising:
a first skin material comprising:
a first exposed part, exposed to a cabin interior; and
a first embedded part, embedded on a cabin exterior side from the first exposed part;

a second skin material comprising:
a second exposed part, exposed to the cabin interior and adjacent to the first exposed part; and
a second embedded part, embedded on the cabin exterior side from the second exposed part and joined to the first embedded part;

a transducer comprising:
a main body, disposed directly back of the first exposed part; and
a wiring part, disposed directly back of at least the first embedded part and electrically connected to the main body, wherein
an end of the wiring part is disposed on the cabin exterior side of the first embedded part; and

a first stitch, suturing the first embedded part and the second embedded part while sewing the wiring part on a back surface of the first embedded part.

2. The interior member according to claim 1 , wherein
the transducer is a sensor that detects a predetermined physical quantity input from a cabin interior side and transmits an electric signal corresponding to the physical quantity.

3. The interior member according to claim 1 , further comprising:
a second stitch, disposed in the first exposed part and tactilely recognizable from a front side, wherein
the second stitch is disposed between a boundary and the main body as seen from the front side, the boundary being between the first exposed part and the second exposed part.

4. The interior member according to claim 3 , wherein
the wiring part is further disposed directly back of the first exposed part; and
the second stitch sews the wiring part on the first exposed part.

5. The interior member according to claim 1 , further comprising:
a flexible part, disposed on a back side of the first skin material, the second skin material, and the transducer, wherein
the end of the wiring part is disposed on the cabin exterior side of the flexible part.

6. The interior member according to claim 5 , wherein
the main body comprises an input region where a predetermined physical quantity is input;
the flexible part comprises a first region disposed on the back side of the input region, a second region adjacent to the first region, a high hardness region, and a low hardness region lower in hardness than the high hardness region; and
at least one of (a) and (b) below is satisfied:
(a) one of the first region and the second region is the high hardness region and the other is the low hardness region; and
(b) one of the two first regions comprised in the flexible part is the high hardness region and the other is the low hardness region.

7. The interior member according to claim 6 , wherein
the high hardness region and the low hardness region are different in material.

8. The interior member according to claim 7 , wherein
at least one of the high hardness region and the low hardness region is made of a foam impregnated with resin.

9. The interior member according to claim 6 , wherein
the high hardness region and the low hardness region are different in thickness in a front-back direction.

10. The interior member according to claim 6 , wherein
at least one of the high hardness region and the low hardness region comprises a through hole that penetrates the interior member in a front-back direction.

11. An interior member comprising:
a first skin material comprising:
a first exposed part, exposed to a cabin interior; and
a first embedded part, embedded on a cabin exterior side from the first exposed part;
a second skin material comprising:
a second exposed part, exposed to the cabin interior and adjacent to the first exposed part; and
a second embedded part, embedded on the cabin exterior side from the second exposed part and joined to the first embedded part;
a transducer comprising:
a main body, disposed directly back of the first exposed part; and
a wiring part, disposed directly back of at least the first embedded part and electrically connected to the main body, wherein an end of the wiring part is disposed on the cabin exterior side of the first embedded part; and

a flexible part, disposed on a back side of the first skin material, the second skin material, and the transducer, wherein the end of the wiring part is disposed on the cabin exterior side of the flexible part, wherein
the main body comprises an input region where a predetermined physical quantity is input;
the flexible part comprises a first region disposed on the back side of the input region, a second region adjacent to the first region, a high hardness region, and a low hardness region lower in hardness than the high hardness region;
at least one of (a) and (b) below is satisfied:
(a) one of the first region and the second region is the high hardness region and the other is the low hardness region; and
(b) one of the two first regions comprised in the flexible part is the high hardness region and the other is the low hardness region; and

the first exposed part comprises: a skin layer, having a light transmitting property; an intermediate layer, disposed on the back side of the skin layer and having a lower light transmitting property than the skin layer; a design layer, disposed on the back side of the intermediate layer and having a lower light transmitting property than the intermediate layer; and a recess, opening on at least one of a front surface and a back surface of the design layer;
the first exposed part comprises a display region formed by the recess and displaying a predetermined design on a front surface of the first exposed part by light irradiated from the back side;
as seen from a front side, the input region and the first region are disposed around the display region, and the second region is disposed in the display region; and
the second region comprises a light introduction hole that introduces the light.
