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.

Claims

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 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.

2. The sensor sheet according to claim 1,

wherein a pair of the wiring lines are provided along the surface direction of the main body while being electrically connected to each of the plurality of detecting portions.

3. The sensor sheet according to claim 1,

wherein the main body has a flexible flat substrate, and the plurality of detecting portions and a pair of wiring regions as a part of the wiring lines are provided in the substrate.

4. The sensor sheet according to claim 3,

wherein the substrate has an air permeable portion through which air is allowed to be circulated as seen in the thickness direction of the main body.
