A vehicle seat has a seat base, a carriage, and an adjusting device. The adjusting device is formed in such a way that the vehicle seat is adjustable vertically or the inclination is adjustable by the adjusting device. The adjusting device has a rotation device arranged on the carriage such that the seat base is rotatable relative to the carriage about a vertical axis by the rotation device. The adjusting device includes a strut, a first end of which is pivotably attached to the carriage or to a rotation base fixed to the carriage and a second end of which is pivotably attached to the seat base. The adjusting device has first and second linear actuators. The seat base is supported on the first linear actuator, the second linear actuator, and/or the strut. The first and second linear actuators cooperate to adjust the vehicle seat.

A reclinable passenger seat including a base, a seat pan frame having a front end connected to the base via a first fixed pivot, a support arm having one end connected to the base via a second fixed pivot aft of the first fixed pivot, and a backrest frame having an upper backrest member and a lower backrest member. An opposed end of the support arm is pivotally connected to the lower backrest member at a first location spaced from the upper backrest member. A rear end of the seat pan frame is pivotally connected to the lower backrest member at a second location between the first location and the upper backrest member. The backrest frame and seat pan frame are configured to move simultaneously between a sitting configuration and a reclined configuration through pivoting motion about the fixed pivots and about the two locations.

A multidirectional control apparatus for a vehicular seat is provided to perform anteroposterior tilting, lateral tilting, control of height and tilting in other directions in consideration of the body size of a passenger and the traveling environment. The multidirectional control apparatus improves passenger comfort by tilting the seat in a lateral direction when entering or exiting a vehicle, prevents the passenger from leaning to one side by tilting the seat in a lateral direction during turning of the vehicle, and offers a safety function of protecting the passenger by inclining the seat in the direction of a collision in the event of a collision of the vehicle.

A passenger seat for an aircraft, including a bottom support configured to be connected to a floor of the aircraft, a seat pan frame, and a support structure interconnecting the seat pan frame to the bottom support, the support structure including a front support member pivotally connected to a front end of the seat pan frame, the front support member including a respective strut on each side of the seat pan frame, each respective strut having a bottom end rigidly connected to the bottom support and an opposed top end located under the seat pan frame, the bottom end being inwardly, downwardly and rearwardly offset with respect to the top end.

A vehicle seat arrangement includes a vehicle seat arranged to be adjusted between a forward facing setup and a rearward facing setup and a seat back rotation axle. A seat back is rotatable around a seat back rotation axle between a forward facing seat back setup and a rearward facing seat back setup. The seat cushion is arranged to be adjusted between a forward facing seat cushion setup and a rearward facing seat cushion setup. The seat back rotation axle may be arranged to be fixed in location and the seat cushion may be arranged to be displaceable horizontally or the seat back rotation axle may be arranged to be displaceable horizontally and the seat cushion may be arranged to be fixed in location.

A rear seat for a vehicle is provided, in which when the seat back is reclined. The angle of the seat cushion is adjusted by following the operation of the seat back to provide an optimal posture for fatigue reduction of a passenger. When the seat back is folded, the seat cushion is not operated.

A seat adjustment mechanism for a vehicle seat is provided. The mechanism may have a number of first pairs of rails, where each first pair of rails has an upper rail and a lower rail. The mechanism may also have a number of second pairs of rails with a substantially same acting direction as the number of first pairs of the pairs.

The present disclosure provides a seat control system for a vehicle, which may sense whether passengers have been seated on a front seat and a rear seat, and easily implement sleep and rest postures of the front seat and the rear seat through the height adjustment, the reclining adjustment, and the like of the front seat and the rear seat according to the sensed result.
