A lifter mechanism for an edge of a seat cushion includes a bracket detachable from and rotatable about a transverse bar. The bracket includes a forward lever and a rearward portion. The forward lever is coupled to a seat suspension. The rearward portion is coupled to a linkage. The linkage is coupled to a seatback. The forward lever raises an edge of the seat suspension upon the seatback pivoting to a predetermined reclined position.

A revolveable door chair for a vehicle includes a support frame including a base, a side member extending upwardly from the base, and a chair support. The side member is pivotally mounted to a vehicle support. A ground support leg is pivotally connected to the base. A chair is positioned in the support frame. The chair rests in the chair support.

A rotation assembly for a vehicle includes a ring gear coupled to a frame of the vehicle and having serrations integrally formed therein and an inner ring that rotatably engages with the ring gear. The inner ring may directly mounted to an underside of guide tracks on a seat.

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.

In order to suppress a claustrophobic feeling that a person sitting on a rear seat receives due to a front seat, and to make the front seat easy to use as an ottoman by the person, a movement adjustment system is used for a passenger seat and a rear seat, and includes a slide rail for moving the rear seat in the front to back direction, and a control part for changing the movement region of the rear seat by the slide rail. The passenger seat has a seat cushion, and a seat back mounted to be changeable between an upright state and a lowered state with respect to the seat cushion. The control part changes the movement region so that the passenger seat and the rear seat can come closer when the seat back of the passenger seat is in the lowered state than in the upright state.

A vehicle system includes a seat state acquisition unit (160) that acquires an orientation about a vertical axis of a seat on which an occupant of a vehicle sits, a vehicle state acquisition unit (170) that acquires a current or future acceleration relating to the vehicle, and a seat control unit (180) 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.

A seat tilting system for tilting a seat, in particular a vehicle seat, may have at least a seat support structure to support and mount the seat, a base platform defining a reference plane, and a number of swivel actuators coupling the seat support structure relative to the base platform. At least a first swivel actuator is configured to swivel the seat support structure with respect to the base platform around a first swivel axis. At least a second swivel actuator is configured to swivel the seat support structure with respect to the base platform around a second swivel axis. At least a third swivel actuator is configured to rotate the seat support structure around a third swivel axis perpendicular to the base platform.

In order to suppress a claustrophobic feeling that a person sitting on a rear seat receives due to a front seat, and to make the front seat easy to use as an ottoman by the person, a movement adjustment system is used for a passenger seat and a rear seat, and includes a slide rail for moving the rear seat in the front to back direction, and a control part for changing the movement region of the rear seat by the slide rail. The passenger seat has a seat cushion, and a seat back mounted to be changeable between an upright state and a lowered state with respect to the seat cushion. The control part changes the movement region so that the passenger seat and the rear seat can come closer when the seat back of the passenger seat is in the lowered state than in the upright state.

A vehicle, includes: a vehicle body, and a side door opening portion opened and closed by a side door, formed at a side of the vehicle body; a seatbelt device having a seatbelt, a tongue plate, and a buckle; and a seat at which the seatbelt device is installed, the buckle being fixed at one side in a transverse direction of the seat, the seat being attached to a floor of a cabin so as to be rotatable about a rotation axis extending in a vehicle vertical direction, and the seat being disposed at a position at which, in a state in which the seat is oriented toward a vehicle rear side, the one side in the transverse direction of the seat is disposed at the side in the transverse direction of the vehicle body, and the buckle and the side door opening portion do not overlap in a vehicle transverse direction.

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.
