Vehicle seat air-conditioning device

A vehicle seat air-conditioning device for use in a seat of a vehicle, the vehicle seat air-conditioning device comprising:

• a blower;
• a ventilation path selection switch;
• a controller that controls the ventilation path selection switch;
• a first temperature sensor that detects a temperature in the cabin of the vehicle;
• a second temperature sensor that detects a surface temperature of a person seated in the seat
• a first ventilation path that leads air drawn in from a first inlet by the blower to the ventilation path selection switch, the first inlet being provided in a seating surface on a seating portion of the seat, the seating portion of the seat being a portion of the seat configured for a person to sit thereon and being separate from a seat back of the seat, the seating surface being a surface for the person to sit;
• a second ventilation path that leads air drawn in from a second inlet by the blower to the ventilation path selection switch, the second inlet being different from the first inlet and provided in a portion of the seat other than the seating surface;
• and
• a third ventilation path that leads at least one of the air led through the first ventilation path by the blower or the air led through the second ventilation path by the blower from the ventilation path selection switch to an outlet provided in the seat,
• wherein the first inlet opens toward an interior of a cabin of the vehicle,
• the first inlet and the second inlet are provided vertically below the outlet,
• at least the first inlet, the second inlet, and the outlet are provided in the seat, and at least the first ventilation path, a portion of the second ventilation path, the ventilation path selection switch, the blower, and the third ventilation path are provided inside of the seat,
• the second inlet is provided at a portion of the seating portion other than the seating surface,
• the ventilation path selection switch has modes for leading air to the third ventilation path, the modes including:
• a first mode in which the first ventilation path is connected to the third ventilation path;
• a second mode in which the second ventilation path is connected to the third ventilation path;
• and
• a third mode in which the first ventilation path and the second ventilation path are connected to the third ventilation path, and
• the controller switches between the modes of the ventilation path selection switch by selecting one of the modes from among the first mode, the second mode, and the third mode,
• wherein the controller switches between the modes of the ventilation path selection switch, based on information indicating a first temperature detected by the first temperature sensor and information indicating a second temperature detected by the second temperature sensor, and
• wherein the controller causes the ventilation path selection switch to execute the first mode when the first temperature detected by the first temperature sensor is lower than a set cabin temperature, and the second temperature detected by the second temperature sensor is lower than a second surface temperature and is higher than or equal to a third surface temperature that is lower than the second surface temperature.

• the controller switches between the modes of the ventilation path selection switch by selecting one of the modes from among the first mode, the second mode, and the third mode,
• a driver seat and a front passenger seat each include a seat back, the driver seat and the front passenger seat each being the seat of the vehicle, and
• the second inlet is provided in:
• one of a side surface of the driver seat that faces the front passenger seat, a back surface on an opposite side from a front surface, or a corner portion stretching from a portion of the side surface to a portion of the back surface of the driver seat, the front surface being in contact with a person seated in the driver seat, the side surface, the back surface, and the corner portion being included in the seat back;
• or
• one of a side surface of the front passenger seat that faces the driver seat, a back surface on an opposite side from a front surface, or a corner portion stretching from a portion of the side surface to a portion of the back surface of the front passenger seat, the front surface being in contact with a person seated in the front passenger seat, the side surface, the back surface, and the corner portion being included in the seat back,
• the second inlet is provided with a cover that is air-permeable,
• the second inlet is provided in the corner portion and the cover is provided over the corner portion, and
• air-permeability of a portion of the cover covering the portion of the side surface included in the corner portion is higher than air-permeability of a portion of the cover covering the portion of the back surface included in the corner portion.
