A vehicle seat includes sheet-shaped sensors configured to detect electric signals associated with the biopotential of a seated passenger, the vehicle seat being configured to remove noise caused due to static electricity to stably measure a bioelectric signal (e.g., heart rate) of the passenger. A seat back includes the sheet-shaped sensors. A cushion pad placed on a seat back frame is covered with a trim cover. Vertically-extending conductive fabric in a belt shape is disposed on an outer surface of the trim cover. The portion where the conductive fabric is disposed has a three-layer structure of the conductive fabric, a skin, and a wadding. A free end of the conductive fabric drawn into the seat back is provided with a J-hook hooked onto a lower frame bridging portion, thus part of the conductive fabric and the lower frame bridging portion contact each other to be electrically conductive with each other. |

1. A vehicle seat comprising:
a seat that comprises a seat frame having electrical conductivity, a cushion pad, and a trim cover that covers the seat frame and the cushion pad; and a sensor that is attached to the seat and detects an electric signal associated with a biopotential of a seated passenger, wherein the vehicle seat measures a heart rate of the seated passenger based on the electric signal detected by the sensor, wherein at least a part of the trim cover is provided with a conductive member disposed on a surface of the trim cover that contacts the seated passenger, wherein a part of the conductive member contacts the seat frame, whereby the conductive member and the seat frame are in electrical conduction with each other, and wherein the sensor comprises a plurality of sensors provided at a respective plurality of portions of the trim cover, and the conductive member is disposed at a position not overlapping with the plurality of sensors, and is provided between the plurality of sensors. |
