Publication number: 20230339367Abstract: A vehicle seat includes a seat cushion and a seatback. The vehicle seat has a plate-shaped pressure-receiving member configured to receive a load from an occupant seated on the vehicle seat and a radio wave sensor fixed to the pressure-receiving member. The radio wave sensor is configured to acquire information about the occupant by emitting radio waves toward the occupant and detecting the radio waves reflected off the occupant. The pressure-receiving member includes a plurality of first ribs that protrudes from a backside of the pressure-receiving member, which is a side facing away from the occupant, in a direction away from the occupant, and a plurality of second ribs that protrudes from the backside in a direction away from the occupant, the plurality of second ribs crossing the plurality of first ribs. The radio wave sensor includes at least one fixing part that is fixed to the pressure-receiving member.Type: ApplicationFiled: June 27, 2023Publication date: October 26, 2023Inventors: Kohei Kowata, Katsuya Kawata

Publication number: 20230105172Abstract: A biological sensor is provided with at least two sensors for detecting vibrations, and is configured so that the at least two sensors form layers. One of the at least two sensors is a first sensor used to acquire biological information, and one is a second sensor used to remove noise. A first cushion material for reducing vibrations is disposed between the first sensor and the second sensor. The first cushion material is integrally laminated with the first sensor and the second sensor. This facilitates accurate detection of biological information.Type: ApplicationFiled: December 8, 2022Publication date: April 6, 2023Inventors: Kohei KOWATA, Tomoari AIBA, Yoritaka DOI

Publication number: 20220144168Abstract: A notification system includes a seat; a luggage detection unit that detects a presence of luggage on the seat or in the vicinity of the seat, the luggage being held by a user; a seating detection unit that detects whether or not the user is seated on the seat; a notification unit that notifies the user of presence or absence information of the luggage; and a control unit that is connected to and controls the luggage detection unit and the notification unit. When the luggage detection unit detects the luggage after an elapse of a predetermined time from when the seating detection unit has detected that the user has left the seat, the control unit causes the notification unit to notify the user that the luggage has been detected.Type: ApplicationFiled: March 3, 2020Publication date: May 12, 2022Inventors: Takayoshi ITO, Yuichiro HOSHI, Kohei KOWATA, Hayato SHIMAZAKI
