An occupant support adapted for use in a vehicle includes a seat mount, a seat, and a motion-sickness mitigation system. The seat mount is adapted to couple to the vehicle for movement with the vehicle. The seat is adapted to provide a comfortable support surface for an occupant of the occupant support.

A seat assembly for a vehicle, the assembly comprising a seat having a frame portion and a rigid control body coupled to the frame portion in a movable manner relative to the frame portion with at least four possible distinct movements, wherein the seat further has a backrest to support the back of a user and a base transversal to the backrest to support the lower limbs of the user, the backrest and the base each being independently rotatable around a pitch axis, the seat assembly comprising driving means configured to translate the seat along a first direction, translate the seat along a second direction distinct from the first direction, rotate the base and rotate the backrest in response to said four movements, respectively.

A motor vehicle including at least one individual seat is provided. The individual seat includes a seat part and a backrest. The seat part has a seat-part main shell and seat-part side shells arranged thereon on respective sides. The backrest has a backrest main shell and backrest side shells arranged thereon on respective sides. A rail system is provided, which moves the respective seat-part side shell and/or the respective backrest side shell in a desired or specified position by way of actuators.

In order to improve steering operation operability during cornering while maintaining a driver holding property, a seat apparatus is provided with: a seat back frame; a cornering sensor for detecting a cornering direction of a vehicle; and a control unit that controls the seat back frame on the basis of the result of detection by the cornering sensor. The seat back frame is provided with: left and right side frames disposed on both sides of the seat back frame; a back plate disposed between the left and right side frames; and a swinging mechanism for swinging the back plate with respect to the direction of movement of the vehicle. The control unit controls the swinging mechanism such that, upon detection of a cornering direction of the vehicle by the cornering sensor, the inner one of the sides of the back plate with respect to the cornering direction is positioned rearward of the outer one of the sides with respect to the cornering direction.

Ramp mounts may facilitate the movement of a passenger seat pan relative to a passenger seat frame during movement of the seat pan between an upright position and a recline position relative to the passenger seat frame. During cycling of the seat pan from the recline position to the upright position, ramp mounts may break. Embodiments of the ramp mount disclosed herein may increase the ramp mount durability so as to reduce the instances of ramp mounts breaking during cycling of the seat pan between the recline and upright positions. Additionally, some embodiments may provide for a ramp mount that has fewer components. Such embodiments may simplify coupling of the ramp mount to a seat pan and may reduce passenger seat system assembly time. Moreover, in some embodiments, the reduced number of components may further reduce manufacturing time and/or coststhereby providing a relatively low cost ramp mount.

An occupant support adapted for use in a vehicle includes a seat frame and a seat pad. The seat frame is adapted to couple with the vehicle for movement with the vehicle. The seat pad is adapted to provide a comfortable support interface for an occupant of the occupant support.

An occupant support adapted for use in a vehicle includes a seat mount, a seat, and a motion-sickness mitigation system. The seat mount is adapted to couple to the vehicle for movement with the vehicle. The seat is adapted to provide a comfortable support surface for an occupant of the occupant support.

Systems and methods for actively isolating a payload from a disturbance. In one example, a seat system for a vehicle includes a seat, a support structure including an actuator configured to move the seat about a pivot axis at a command angle, a sensor positioned to detect vehicle movement, and a controller configured to determine a vehicle roll angle based on an input from the sensor, generate a variable gain based at least on a vehicle roll acceleration determined from the input, wherein the variable gain modulates a gain of a band-pass filter having a fixed bandwidth, generate a command signal based at least on the vehicle roll angle, the controller configured to adjust a magnitude of the command signal relative to an amplitude of the input and apply the band-pass filter, and provide a force command to the actuator to move the seat at a desired command angle.

An occupant support includes a seat coupled to a seat base. The seat includes a seat bottom and a seat back. The seat back is coupled to the seat bottom to extend upwardly away from the seat bottom. Motion-sickness mitigation means facilitates relative movement between a support surface of the seat and the seat base.

In order to improve steering operation operability during cornering while maintaining a driver holding property, a seat apparatus is provided with: a seat back frame; a cornering sensor for detecting a cornering direction of a vehicle; and a control unit that controls the seat back frame on the basis of the result of detection by the cornering sensor. The seat back frame is provided with: left and right side frames disposed on both sides of the seat back frame; a back plate disposed between the left and right side frames; and a swinging mechanism for swinging the back plate with respect to the direction of movement of the vehicle. The control unit controls the swinging mechanism such that, upon detection of a cornering direction of the vehicle by the cornering sensor, the inner one of the sides of the back plate with respect to the cornering direction is positioned rearward of the outer one of the sides with respect to the cornering direction.
