Abstract
A seat with a ventilation system that maintains seated person's coolness by blowing air to minimum segments of a seatback and a seat cushion so that seated person's comfort is maintained is provided. Air-blowing means is controlled in air-blowing quantity and air-blowing time periodically by air-blowing control means, and air blowing in each period is set to include a first term T1 in which a predetermined quantity of air is blown and a second term T2 in which the predetermined quantity of air to be blown is gradually reduced.
Claims15
A seat with a ventilation system comprising:
- a seat cushion and a seatback;
- an air-blower blowing air to an outside of one or both of a seating surface of the seat cushion and a backrest surface of the seatback;
- an air-blowing controller controlling the air-blower to control air-blowing quantity and air-blowing time cyclically,
- wherein, air blowing in each cycle includes a first term in which a predetermined quantity of air is blown and a second term in which the predetermined quantity of air to be blown is reduced over time, and
- wherein a period of the first term is the same as a period of the second term, and
- wherein each of the seat cushion and the seatback includes an aerated layer, to which the air from the air-blower is introduced, extending along a covering material of the seat cushion and the seatback, the aerated layer is divided into a plurality of segments by a plurality of spacers that allows air to pass between adjacent segments, and each segment includes a vent that discharges air supplied by the air-blower,
- wherein a period of the air blowing is longer than 30 seconds within a range shorter than 240 second, and
- wherein the air-blowing controller abruptly increases the quantity of air to the predetermined quantity of air to be blown in the first term at an end of the second term.
