A conveyance seat includes: a seat base; a support portion which supports the occupant from the back side; a flip-up mechanism which flips up the seat base; a biasing member which biases the support portion forward; an engagement portion which is engaged with the support portion to hold the support portion in a upright state against the biasing force; a cancel mechanism which cancels the engagement between the engagement portion and the support portion; and a return mechanism which returns the support portion from a state where the engagement with the engagement portion is canceled by the cancel mechanism to a state where the support portion is engageable with the engagement portion. The return mechanism performs the return operation in accordance with the inclination angle of the support portion inclined forward by the biasing member after the engagement between the engagement portion and the support portion is canceled.

To provide a seat for vehicles in which a seat cushion escape mechanism can be space-saving, the seat having an escape mechanism to shift a seat cushion frame disposed on a base part from a seating posture to an escape posture with the frame placed forward of the base part includes: a support leg part having one end rotatably connected to the frame and the other end rotatably connected to the base part; a guide part to be engaged with the one end of the support leg part to guide the one end so as to lift the one end; a coil spring biasing the support leg part so as to have the one end guided by the guide part and flip up a portion connected with the frame; and a second coil spring which is provided at the other end and applies a biasing force so as to rotate the one end of the support leg part forward with the other end as a center.

A vehicle slouch seat having a carriage that includes a front side and a rear side. A link element is located on a rear side of the carriage and a slideable element is located on the front side of the carriage. A cushion is movable in an upward direction with the carriage connected to a base structure at one of a plurality of latch points. The cushion is prevented being rotated in the upward direction via a cushion rotational prevention structure with the carriage connected to the base structure at another one of the plurality of latch points.

A transport seat system, in particular aircraft seat system, includes at least one first seat, with at least one mounting module that is configured, for the purpose of mounting the seat, to be connected on a guide rail, and with at least one second seat, which is arranged behind the first seat with at least one mounting module that is configured, for the purpose of mounting the seat, to be connected on the same guide rail, the two seats being configured, for the purpose of implementing a usage position and a stowage position of at least one of the seats, to be displaced on the guide rail relative to one another, wherein

at least one mounting module of at least one of the seats includes a seat foot unit, which is movably supported relative at least to a portion of the mounting module.

An automobile seat includes a seat main body having a seat cushion frame; a seat supporting member; a link mechanism which allows the seat main body to shift between a first seat position and a second seat position corresponding to a forward-leaning posture; and a seat lock mechanism capable of being switched between a seat-locked state in which the seat main body is restrained at the first seat position and a lock-released state. The seat cushion frame is supported in a manner that a position thereof backward of the front link is suspended by the seat supporting member via the rear link. At the first seat position, a free-end supporting point of the rear link is positioned backward of a first vertical line passing a fixed-end supporting point of the rear link, and at the second seat position, the free-end supporting point is positioned forward the first vertical line.

A vehicle seat capable of housing a seat main body includes a seat pivot shaft to which the seat main body is connected to be pivotable, and a detachable leg whose upper end is mounted to the seat main body and whose lower end is detachably held onto a leg holding member on a vehicle body floor. When the seat main body moves from a housed state side to a usage state side, a leg guide portion causes a cushion abutting portion to abut a base abutting portion in advance, thereby guiding the detachable leg moving together with the seat main body to pass above a leg movement inhibiting portion which is a portion of a support base.

The invention relates to a vehicle seat (1) comprising a seat element (2) that can be vertically adjusted from an operational position to a stowed position. Said vehicle seat has a first locking element for securing the seat element in the operational position, and a positioning means for positioning the seat element in a transitional position, the seat element being manually transferable directly or indirectly from the transitional position to the stowed position.

A stowable seat assembly having a seat back and a seat bottom. The seat bottom has a seat bottom frame that includes a drive link that is pivotally connected to a front link and the seat back. A pivot link is pivotally connected to the drive link and a side member of the seat bottom frame.

A seat device for a vehicle includes: a seat cushion and a seat base of a rear row seat, the seat base mounted on a floor of a vehicle standing upward from the floor and forming a support structure of the seat cushion; a movable cushion portion forming a sitting surface for a passenger; a seat-cushion-moving mechanism to rotate and translate the movable cushion portion so that the movable cushion portion moves between a seating position, an extended position, and a tray position. In particular, a passenger sits on the movable cushion portion in the seating position, the movable cushion portion rotates away from the seat base in the forward direction to expose a lower side of the movable cushion portion in the extended position, and the tray position is obtained when the movable cushion portion translates rearwardly from the extended position with the lower side remaining exposed.

An airplane seat device with at least one airplane seat is at least configured to be adjusted between a use position and a stowage position.

In the stowage position, the airplane seat has a maximum height which is equal to or less than a maximum height in the use position.
