A cushion support memberincludes: a lower regionwhose left-right full width is less than an interval between a pair of side framesof a seat back frame; an upper regionlocated above the lower regionand having a left-right full width greater than the lower region. the upper regionis divided into a central regionincluding a central part in the left-right direction and provided with a predetermined left-right width, and outer regionsprovided on outer sides with respect to the central regionin the left-right direction, and the central regionis arranged as a retracted region which is cut off to leave the outer regionsor is recessed to a side opposite to a cushion member with respect to the outer regions

Vehicle seat

A vehicle seat control system () includes an angle detection unit () that detects an angle of a connection unit () that rotatably connects a seat surface portion to a backrest portion (), a frame body () that includes a pair of vertical frames () and a horizontal frame () connecting the pair of vertical frames to each other and is provided to be stored in the seat surface portion, a leg support portion () including a first rotation shaft (Lb) parallel to an extending direction of the horizontal frame and is provided inside the frame body to be rotatable with respect to the frame body, a driving unit () that is provided at a proximal end (B) of at least one of the pair of vertical frames and rotates the frame body taken out from the seat surface portion around a second rotation shaft (La) parallel to the extending direction of the horizontal frame, and a control unit () that controls the driving unit on the basis of a detection result of the angle detection unit at least at the time of automatic driving of the vehicle.

Vehicle seat control system, vehicle seat control method, and storage medium

A vehicle system includes a seat on which an occupant of a vehicle is seated, a first operation reception unit and a second operation reception unit configured to be operated by the occupant, and a seat drive unit configured to change a position of the seat on the basis of an operation received by the first operation reception unit, and return the position of the seat to a position before being changed by the first operation reception unit when an operation is received by the second operation reception unit, and the second operation reception unit is provided at a rearward position relative to a place corresponding to a central portion in a travel direction of a seating portion of the seat in a side member provided in a side portion of the seat.

Vehicle system, vehicle control method, and vehicle control program

A seat apparatus includes: a seat on which a passenger of a vehicle sits; an inputter which is operated by the passenger; a fixer which fixes a position of the seat until the inputter is operated by the passenger and allows the position of the seat to be movable in a longitudinal direction of the vehicle when the inputter is operated by the passenger; and a restrictor which restricts the movement of the seat when a predetermined condition related to a traveling state of the vehicle or an external environment of the vehicle is satisfied in comparison with a case in which the predetermined condition is not satisfied.

Seat apparatus

A vehicle system includes a seat state acquisition unit () that acquires an orientation about a vertical axis of a seat on which an occupant of a vehicle sits, a vehicle state acquisition unit () that acquires a current or future acceleration relating to the vehicle, and a seat control unit () that deforms at least a part of the seat on the basis of the orientation of the seat acquired by the seat state acquisition unit and the acceleration acquired by the vehicle state acquisition unit.

Vehicle system, vehicle control method, and storage medium

A seat apparatus for a vehicle includes a conversion mechanism that converts a disposition of a seatback between a normal position to a converted position, the normal position being a position at which the seatback is disposed at a rear section of the seat cushion and a sitting direction of an occupant is facing forward, the converted position being a position at which the seatback is disposed at a front section of the seat cushion and a sitting direction of an occupant is facing rearward, and a reclining mechanism that biases the seatback toward a neutral position at which the seatback stands upward and that reclines the seatback forward and rearward from the neutral position.

Seat apparatus for vehicle

A vehicle seat apparatus includes: a seat main body configured to seat an occupant; a first gear that is joined to the seat main body; a second gear that is capable of being engaged with the first gear; a rotation mechanism that rotates the second gear in a state of being engaged with the first gear and that rotates the seat main body in a yaw direction from a reference direction; a biasing part that applies, when the seat main body is rotated by the rotation mechanism, a biasing force in a direction that is opposite to a rotation direction; and a release control part that releases an engagement between the first gear and the second gear, that rotates the seat main body by a biasing force which is preliminarily biased by the biasing part, and that allows the seat main body to return to the reference direction.

Vehicle seat apparatus

A vehicle control system includes a seat () on which an occupant of a vehicle sits, a first protruding mechanism () configured to move a pushing member (A) provided inside the seat to adjust a protruding position and a displacement of the seat, a second protruding mechanism () configured to inject a gas or liquid into a bag-like member (B) provided inside the seat to adjust the protruding position and the displacement of the seat, and a seat control unit configured to control the first protruding mechanism to cause at least a part of a contact portion between the occupant and the seat to protrude in a case that the vehicle performs a first driving mode having a degree of automated driving less than a predetermined reference and to control the second protruding mechanism to cause at least a part of the contact portion between the occupant and the seat to protrude in a case that the vehicle performs a second driving mode having a degree of automated driving equal to or higher than the predetermined reference.

Vehicle control system, vehicle control method, and recording medium

A vehicle seat control system () includes a first backrest portion () rotatably connected to a seating portion () by a first connection unit (), a second backrest portion () rotatably connected to the first backrest portion by a second connection unit (), a folding adjustment unit () that adjusts an angle of the second connection unit, a seat surface adjustment unit () that adjusts a height of the seating portion, a first angle detection unit () that detects a first angle that is formed between the first backrest portion and a floor surface, a second angle detection unit () that detects a second angle that is formed between the second backrest portion and the first backrest portion, and a control unit () that controls the folding adjustment unit on the basis of the first angle at the time of automatic driving of the vehicle to adjust the second angle, and controls the seat surface adjustment unit to maintain a height of a reference position in the second backrest portion to be equal to or greater than a reference height in a case that the height of the reference position in the second backrest portion is smaller than the reference height.

A method of calculating a reliability effective in a decoding process of hologram. An optical information reproducing apparatus that reproduces information with the use of the holography includes an image acquisition unit that reproduces two-dimensional data from a hologram disc, an image equalization unit that makes the two-dimensional data equal to target data having a target PR characteristic, a soft output decoding unit that decodes output data of the image equalization unit on the basis of the PR characteristic, and outputs a decoded result having a reliability, and an error correction unit that conducts an error correction of the data on the basis of the decoded result.
