A seating posture is stabilized for the shoulders of a passenger seated on a vehicle seat. A vehicle seat is provided with a seat back configured to support the seated person from the rear. A shoulder support portion of the seat back configured to support a corresponding one of the shoulders of the seated passenger includes an air cell configured to expand when air is supplied. When the air cell expands, one end portion of the shoulder support portion on the outside in the width direction of the vehicle seat moves more forward than the other end portion of the shoulder support portion on the inside in the width direction.

A lumbar support for a vehicle seat includes: a support panel made of an elastic material and supporting the user's lumbar vertebra; a first guide rod supporting the support panel; a second link bracket fastened to the first guide rod to be movable up and down; a first link bracket disposed under the second link bracket to be movable up and down with respect to the second link bracket, and having an operation block providing a supporting force to the lumbar vertebra; a first rotary screw vertically extending, thread-fastened to the first link bracket, and moving up and down the first link bracket by rotating about a longitudinal axis; and a second rotary screw vertically extending, thread-fastened to the second link bracket, and moving up and down the second link bracket by rotating about a longitudinal axis.

A mesh integrated seat pad assembly delivers vibration output from a massage module to the entire seat pad to prevent the vibration from being reduced by the pad. The mesh integrated seat pad assembly includes a pad provided in a seatback supporting the back of a passenger or a seat cushion supporting the hip and the thigh of the passenger to provide additional comfort to the passenger, a mesh mounted on one side surface of the pad, and a massage module installed to be in contact with the mesh.

There is provided a technique by which posture changing can be given to an occupant while the forward shift of his/her hip portion is prevented. A seat for vehicle includes a seat cushion, and a seat back coupled to the seat cushion, and the seat back includes a posture changing mechanism having a back face supporting mechanism. There is provided a technique by which a fatigue reduction operation using the posture changing mechanism includes a) moving the back face supporting mechanism set to a position of a lumbar spine portion of an occupant from a first position state to a rear direction side and setting the back face supporting mechanism to a second position state, and b) thereafter, moving the back face supporting mechanism stepwise to a front direction side from the second position state to the first position state.

A vehicle control method is disclosed which is a method for adjusting a seat inside a vehicle. The vehicle control method includes: monitoring the surroundings of a passenger sitting in the seat through a camera installed inside the vehicle; sensing an object around the passenger through the monitoring; sending information on the sensed object to a server; receiving a preset seat setting value corresponding to the object information from the server; and adjusting the position of the seat according to the seat setting value. One or more of an autonomous vehicle according to the present invention, a user terminal, and a server may be associated with artificial intelligence, a robot, augmented reality (AR), virtual reality (VR), etc.

A seat for a vehicle may include a seatback including one or more inflatable bladders that may be configured to provide adjustable lumbar support and to deploy in response to a triggering event signal indicative of a change of velocity, collision, or predicted collision event. One or more inflatable bladders may be configured to be independently controllable and configured to provide adjustable lumbar support at a region of the seatback during normal vehicle operation. Moreover, when at least a portion of the back of an occupant of the seat pushes against a front surface of the seatback due to the event, the one or more inflatable bladders may be configured to compress at least partially a comfort foam or comfort material in the seatback and expedite engagement of the energy absorbing material with the occupant's back.

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.

A passenger seat for a passenger vehicle including but not limited to an aircraft may include a seat base, a seat back, and an energy absorption system. The energy absorption system is spherically coupled to the seat base and spherically coupled to the seat back, and includes a dampening member and a support assembly. The dampening member is movable relative to the support assembly responsive to a load applied on the seat back such that engagement between the support assembly and the dampening member dampens the load.
