A vehicle seating system includes a vehicle floor, a fixed ring fixed to the vehicle floor, a rotatable ring concentric with and rotatably supported by the fixed ring, a seat supported on the rotatable ring, and a retractor fixed to the rotatable ring.

A convertible seating and dinette arrangement that includes moveable and adjustable first and second seats with each seat including a base, a seat bottom, and a backrest; and wherein each base is configured for pivotal movement to adjust between various modes. The convertible seating and dinette arrangement can include seats that are moveable and convertible to at least three different modes including a sofa mode, a recliner mode, a daybed mode, a dinette mode, an alternate dinette mode, and a chaise lounge mode.

A locking block is fixed with respect to a seat cushion. A locking pin which can advance and retract relative to the locking block is provided on a main frame side. A V groove shape receptacle is formed on the locking block. When the locking pin is advanced into the receptacle portion, the locking pin is guided by a receiving inclined surface of the receptacle portion forming the V-shape groove, and advances to a bottom of the receptacle portion. With this process, the locking block moves in a rotational direction B, and when the locking pin engages the bottom, the seat cushion is fixed.

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 seating system includes a vehicle floor, a fixed ring fixed to the vehicle floor, a rotatable ring concentric with and rotatably supported by the fixed ring, a seat supported on the rotatable ring, and a retractor fixed to the rotatable ring.

A device for tilting and swiveling a seat of a vehicle is provided. The device performs a tilting operation for relaxation by cooperation of a seat back and a seat cushion as well as a swiveling operation for rotating the seat in an indoor direction for conversion between passengers or rotating the seat in an outdoor direction for getting on and off vehicle assistance.

A vehicle provides a comfortable space for a wide range of passengers. The vehicle (1) includes a plurality of seats (31) arranged in a fore and aft direction in a cabin (5) of the vehicle, each seat being supported in the cabin so as to be rotatable around a vertically extending rotational axis. Preferably, at least one of the seats includes a support column (32) extending vertically from a floor (6) of the cabin, and a seat cushion (33) supported at an upper end of the support column so as to be rotatable around the vertically extending rotational axis.

A seating system is provided which comprises a seat movable between a standard seating position, in which the seat faces frontwards and the seat backrest is in an upright position for conventional driving mode, and at least one non-standard seating position in which the seat is rotated around a vertical axis with respect to the standard seating position and the backrest is reclined rearwards by rotation around a first transverse horizontal axis from the standard seating position. The seat is equipped with at least one passive safety device switchable between a working or active state, in which the device is able to protect an occupant of the seat in case of an impact of the vehicle, and a non-working or inactive state.

There is provided a vehicle seat that includes: a waist movement suppressing member that is disposed at a seat front side and a seat upper side of a seat cushion, and that extends in a seat width direction; movable members that support both end portions of the waist movement suppressing member movably in a seat vertical direction; urging members that urge the movable members toward a seat upper side; raising mechanisms that, at a time of sudden braking or at a time a collision is predicted, move the waist movement suppressing member toward the seat upper side; and stoppers that limit movement, toward a seat lower side, of the waist movement suppressing member that has been moved toward the seat upper side by the raising mechanisms.

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.
