Abstract

A sensor sheet has a planer shape to be disposed on a surface of a vehicle seat. The sensor sheet includes: a pliable planar main body capable of being disposed along the surface of the vehicle seat; a plurality of detecting portions provided in the main body; and a wiring line that is configured to supply power to each of the detecting portions, wherein each of the plurality of detecting portions is configured to transmit information detected from the surface of the vehicle seat to a controller through a wired or wireless communication, wherein the main body has an air permeability to enable circulation of air in a thickness direction, and wherein the plurality of detecting portions are arranged at a suitable interval in a surface direction of the main body.

First claim

What is claimed is:

1. A sensor sheet having a planer shape to be disposed on a surface of a vehicle seat, the sensor sheet comprising:
a pliable planar main body configured to be disposed along the surface of the vehicle seat;
a plurality of flexible flat substrates provided in the main body;
a plurality of detecting portions provided on upper surfaces of the plurality of flexible flat substrates; and
a wiring line provided on the upper surfaces of the plurality of flexible flat substrates and that is configured to supply power to each of the detecting portions, wherein
each of the plurality of flexible flat substrates has a band shape and the plurality of flexible flat substrates are arranged in a parallel manner at suitable intervals in the main body,
each of the plurality of detecting portions is configured to transmit information detected from the surface of the vehicle seat to a controller through at least one of a wired and a wireless communication,
the main body has an air permeability to enable circulation of air in a thickness direction of the main body, and
the plurality of detecting portions are arranged at suitable intervals on the upper surfaces of the plurality of flexible flat substrates.

2. The sensor sheet according to claim 1 ,
wherein the wiring line is a pair of the wiring lines provided along the upper surfaces of the plurality of flexible flat substrates such that the pair of wiring lines is electrically connected to each of the plurality of detecting portions.

3. The sensor sheet according to claim 1 , wherein
the plurality of detecting portions and a pair of wiring regions, as a part of the wiring line, are provided on the plurality of flexible flat substrates.

4. The sensor sheet according to claim 3 , wherein
each of the plurality of flexible flat substrates has an air permeable portion through which air is allowed to be circulated in a thickness direction of the main body.

5. The sensor sheet according to claim 4 , wherein
the air permeable portion is a plurality of air permeable portions provided at positions on each of the plurality of flexible flat substrates that are different than the plurality of detecting portions.

6. The sensor sheet according to claim 1 , wherein
a plurality of back-lining portions are provided on a backside surface of each of the plurality of flexible flat substrates opposite to the upper surface of each of the plurality of flexible flat substrates on which the plurality of detecting portions are provided to support each of the plurality of detecting portions.

7. The sensor sheet according to claim 3 , wherein
the pair of wiring regions are spaced from each other and extend in a parallel manner along each of the plurality of flexible flat substrates on opposite sides of the plurality of detecting portions arranged at the suitable intervals along the upper surfaces of each of the plurality of flexible flat substrates.
