An airbag support device for a vehicle swivel seat includes: a support frame disposed on a lateral side of a seat back frame; a side airbag disposed on a rear plate of the support frame; a plurality of support bars disposed in an extendable manner on a lateral plate of the support frame; an extension drive bar configured to extend such that the extension drive bar connects the plurality of support bars to each other while extending; and a support bar extension drive assembly, connected to the rear plate of the support frame and the extension drive bar, wherein the support bar extension drive assembly is configured to push the extension drive bar inward and outward and at the same time to extend the support bar when the side airbag is inflated.

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.

The invention relates to a vehicle seat having a seat part and a backrest part comprising a first backrest portion and a second backrest portion arranged above it in the seat height direction, wherein the second backrest portion is displaceable relative to the first backrest portion by means of a displacement movement directed at least in the seat width direction, wherein in a first displaced position of the second backrest portion a mechanical interaction is formed between the first backrest portion and the second backrest portion, which secures the first displaced position of the second backrest portion and which can be released by means of a force exerted on the second backrest portion and acting in the direction of the displacement movement.

A seat for a work vehicle includes a bottom frame fixed to a seat bracket supported to a vehicle body frame, a top frame supported to the bottom frame to be vertically slidable relative thereto, a setting tool for setting the top fame to the bottom fame at a plurality of vertically adjustable position, a seat cushion attached to the bottom frame and a seat back. The seat back consists of an upper seat back attached to the top frame and a lower seat back attached to the bottom frame.

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 seat for a work vehicle includes a bottom frame fixed to a seat bracket supported to a vehicle body frame, a top frame supported to the bottom frame to be vertically slidable relative thereto, a setting tool for setting the top fame to the bottom fame at a plurality of vertically adjustable position, a seat cushion attached to the bottom frame and a seat back. The seat back consists of an upper seat back attached to the top frame and a lower seat back attached to the bottom frame.

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.

A vehicle includes: a front seat that is arranged to face rearward in a travel direction; and a rear seat that is arranged, at a rear side of the front seat, to face frontward in the travel direction. At least part of a floor below the front seat is constituted of a flat floor part. A seat portion of the front seat is capable of being flipped up such that a vehicle front side of the seat is a fulcrum point.

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.

A vehicle seat includes: a seat cushion having a seat cushion body and a seat cushion front portion, the seat cushion front portion being provided in front of the seat cushion body and configured to be in contact with and distanced from the seat cushion body, and the seat cushion being configured to be rotated so as to be set to a traveling position facing a front of a vehicle and an ingress and egress position facing a side door; and an expansion and contraction mechanism configured such that the seat cushion front portion is brought into contact with the seat cushion body as the seat cushion rotates from the traveling position to the ingress and egress position, and the seat cushion front portion is distanced away from the seat cushion body as the seat cushion rotates from the ingress and egress position to the traveling position.
