A swivel device for vehicle seats may rotate a seat mounted inside a vehicle at 180° or more and firmly fix the seat at a normal position before and after rotation. The swivel device includes: a base plate provided with a plurality of first locking members; a swivel plate disposed on the base plate to be rotated by a second motor; a rotary force transmission mechanism mounted on an output shaft of the second motor and the swivel plate to transmit a rotary force of the second motor to the swivel plate; an elevating plate provided with a plurality of second locking members separably coupled to the plurality of first locking members and formed on a lower surface of the elevating plate; and a first motor mounted on an upper surface of the elevating plate to transmit a rotary force to the lead screw.

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 seating system for at least one occupant in a vehicle interior is disclosed. The seating system may provide a seat assembly with a base assembly configured to be mounted in the vehicle interior and a seat structure configured to be coupled to the base assembly and providing a seat configured for movement relative to the base assembly. Movement of the seat relative to the base assembly may be made by at least two of recline movement or swivel movement or tilt movement. Recline movement may be generally translating movement of the seat structure. Swivel movement may be rotational movement of the seat structure. Tilt movement may be generally translating movement of the seat structure transverse to recline movement. The base assembly may be a mechanism configured to facilitate movement of the seat structure relative to the base assembly.

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.

The invention relates to a vehicle seat with a lower part for arrangement on a body part of a commercial vehicle and an upper part for storing a seat part, wherein the vehicle seat has a longitudinal adjustment device, by means of which the upper part is displaceable relative to the lower part in the longitudinal direction and/or width direction of the vehicle seat, and a rotational adjustment device working independently of the longitudinal adjustment device, by means of which rotational adjustment device at least parts of the upper part are rotatable relative to the lower part about an axis in the height direction of the vehicle seat, wherein a virtual plane is provided, which is arranged intersectingly parallel to a longitudinal direction and a width direction of the vehicle seat as well as the longitudinal adjustment device and the rotational adjustment device, wherein the longitudinal adjustment device and the rotational adjustment device are designed to be electrically driven.

A device for adjusting a position of a headrest for a vehicle includes: a stay mounted on a seatback frame; a main frame including a rotation guide hole, inserted into and mounted on the stay, and configured to ascend or descend along the stay; an elevation device mounted on the main frame and the stay, and configured to allow the main frame to ascend or descend along the stay; a rotating frame including a first end portion inserted into the stay and configured to ascend or descend along the stay, and a second end portion extending toward the rotation guide hole of the main frame; a rotating device mounted on the rotating frame and the rotation guide hole of the main frame, and configured to rotate the rotating frame along the rotation guide hole; and a headrest frame assembled to the rotating frame.

A vehicle occupant protection device includes: an airbag main body that includes a front-rear chamber that is deployed to a seat front side along a side of a head of an occupant by a gas ejected from an inflator operated when a collision of a vehicle is detected or predicted, and a tip end chamber that is deployed inward in a seat width direction from an end portion of the front-rear chamber on the seat front side; and a headrest that includes a main body portion that supports the head of the occupant from a seat rear side, and a side portion that is provided on at least a side of the main body portion, that protrudes to the seat front side until a deployment of the front-rear chamber is completed, and that is interposed between the front-rear chamber and the head of the occupant.

A wheel loader representing a work vehicle includes an operator's seat, an armrest, and a seat operation portion. The armrest is provided lateral to the operator's seat. The seat operation portion controls a position or a posture of the operator's seat. The seat operation portion is attached to the armrest.

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 kinetic seat assembly that rotates based on a force applied on an occupant seated therein is provided. The kinetic seat assembly includes a primary seat cushion frame, a primary seat back frame, a secondary seat cushion frame pivotally connected to the primary seat cushion frame, and a secondary seat back frame pivotally connected to the primary seat back frame. The kinetic seat assembly further includes a front pivot mechanism for damping movement between the primary seat cushion frame and the secondary seat cushion frame in a kinetic seat vertical direction, and an upper pivot mechanism for damping movement between the primary seat back frame and the secondary seat back frame in a kinetic seat longitudinal direction.
