An assembly comprises a seat bottom and a seat back pivotally attached to the seat bottom. The seat back is pivotal between a fold-forward position and an in-use position. A headrest is pivotally attached to the seat back by a tilt mechanism and is pivotal between a folded position and an upright position via the tilt mechanism. The tilt mechanism pivots the headrest forward to the folded position in response to the seat back being pivoted to the fold-forward position. A headrest-return mechanism is operably coupled to the seat back and to the headrest, wherein the headrest-return mechanism actuates the headrest such that the headrest is pivoted from the folded position to the upright position in response to the seat back being pivoted from the fold-forward position to the in-use position.

A vehicle seat is disclosed. The vehicle seat includes reclining lock mechanisms for releasably locking a seat back, a first releasing mechanism for unlocking the reclining lock mechanisms and causing the seat back to be brought to a condition where the seat back is allowed to be pivoted forward and rearward, the first releasing mechanism including a collapsible link bar member 70, a braking link 71 having a laterally projecting induction pin 72, a first link plate 73, and a first operating lever 7, a tipping-up lock mechanism for releasably locking a seat cushion, the tipping-up lock mechanism including cutout teeth 52a to 52c provided at the seat cushion, and a latch 80 and a cam member 81 which are supported to the seat back, and a second releasing mechanism for unlocking the tipping-up lock mechanism and causing the seat cushion to be brought to a condition where the seat cushion is allowed to be pivoted, the second releasing mechanism including a recess portion 80d formed in the latch 80 for allowing the cam member 81 to be swung up, a second link plate 82, and a second operating lever 8.

A seat system (1) for a vehicle, includes a plurality of seats (2.1 to 2.3) which are disposed next to one another and at least two of which are pivotable about a common pivot axis (S). At least one of the seats (2.2) that are pivotable about the common pivot axis (S) is designed in such a way that when the seat is unlocked and the backrest thereof is pivoted by more than a predefined angle of inclination, the adjacent other seat (2.1) is blocked in the unlocked state or at least the folding movement of the backrest thereof is dampened or prevented.

A system and method for controlling movement of a seat in a vehicle includes a lower seat assembly and an upper seat assembly adjustable relative to the lower seat assembly. An actuator assembly pivotally attached between the lower seat assembly and upper seat assembly selectively adjusts the upper seat assembly relative to the lower seat assembly between at least one upright position and at least one folded position. A control unit selectively actuates a motor and the actuator assembly to control movement of the upper seat assembly relative to the lower seat assembly. The control unit adjusts the position of the actuator assembly to releasably secure the motor in response to the position value detected by a sensor assembly to place the upper seat assembly in position relative to the lower seat assembly.

A seat and seat back assembly includes a seat back moveable between an upright position and a horizontal position. A support panel is connected to the seat back for pivoting movement of the support panel between a first position supporting the seat back upright, and a second position wherein the seat back is moveable into the horizontal position. A biasing mechanism serves to urge the support panel into the first position when the seat back is moved into an upright position. When the support panel is moved into the second position this allows the seat back assembly to move into the horizontal position without dropping unrestricted.

A vehicle seat including: a tilt down mechanism configured to sink down a seat cushion in conjunction with forward tilting down movement of a seat back, wherein the tilt down mechanism couples a rear part of the seat cushion to a base on a floor by a rotary shaft, couples a front part of the seat cushion to the base via a front link, and further includes a power transmission member that couples the front link and the seat back, and wherein the power transmission member is configured by a link member of a rigid body and is configured to, when the seat back is raised from a forward tilted down position, transmit the movement of the seat back to the front link to raise the front link to thus pull up the seat cushion from a downward sunk position.

A vehicle seatback folding device includes: a cushion bracket; a back side frame rotating on the cushion bracket; a spring mounting bracket coupled to rotate integrally with the back side frame around a hinge-coupling part; a return spring for applying, to the back side frame, elastic restoring force for rotating the back side frame in the folding direction of a seatback; and a reverse spring supported in a state in which a first end portion is caught by the spring mounting bracket and a second end portion is caught by a first spring support end.

A headrest assembly having a bracket mount affixed to an upper portion of a seatback frame and at least one headrest bun supporting tube pivotally secured to the bracket mount. A spring biased cam is pivotally secured to the bracket mount and, in a normally biased position, engages an underside projection of a selected one of the supporting tubes, the cam also having an outwardly projecting pin. At least one wheel shaped component is rotatably mounted to an exterior of the bracket mount in proximity to the cam, the wheel having an outer circumferential location which, upon being rotated, contacts the projecting pin causing the cam to pivot in a downward unseating direction from the supporting tube, triggering release of the headrest and supporting tubes in a forwardly rotating and dump position.

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.

A vehicle seat includes a seat back is coupled to a seat base for movement between an upright position and a folded-forward position when a vehicle seat recliner is in an open configuration. The vehicle seat includes a recliner hold-open mechanism that locks the recliner in the open configuration even after a user releases a handle or otherwise disengages an actuator of the recliner. The seat back is thus free to move between the upright and folded-forward positions without the user being required to hold the actuator in any particular position during the movement. The hold-open mechanism may be configured to cooperate with a seat-base motion controller to free the vehicle seat for movement along a foundation frame while the seat back is between the upright and folded-forward positions.
