A vehicle seat includes a base provided on a floor; a seat back pivotably provided on the base; a seat cushion pivotably provided on the seat back; and a reclining drive unit connected to the base and the seat back to make the seat back pivot relative to the base, wherein the reclining drive unit is disposed more rearward than a front end of the seat cushion.

A vehicle seat device comprises: a seat disposed at a vehicle width direction inner side of a side door of a vehicle; a rotating mechanism that rotates the seat about a vertical axis relative to a vehicle body; a sideways movement mechanism that moves the seat in a vehicle width direction relative to the vehicle body between a normal region and an inner region; and a control device which, when causing the rotating mechanism to rotate the seat, causes the sideways movement mechanism to move the seat from the normal region to the inner region before the rotation.

An embodiment rail device includes an upper rail, a first bearing support on the upper rail, a lower rail, a bearing connection end on the lower rail and inserted into the first bearing support, a vertically elongated bearing contact adjustment hole on the lower rail, an upper bearing rotatably connected to the bearing connection end and in close contact with a floor of the first bearing support, a lower plate including a fastening groove that receives a lower end of the lower rail, a bearing shaft mounting hole on a wall surface portion of the fastening groove and matched with the bearing contact adjustment hole, a second bearing support outside the fastening groove and having an opened upper portion, a lower bearing rotatably disposed within the second bearing support, and a bearing shaft fastened to the bearing shaft mounting hole and the bearing contact adjustment hole by a screw.

A seat system includes: a base; a seatback; at least one recliner connecting the base and the seatback to each other for pivoting of the seatback relative to the base; a slider coupled to the base and configured for sliding engagement with a track having a detent region and a tilt-and slide region; and an electronic controller, wherein without mechanical interlock between the recliner and the slider, the electronic controller causes the recliner to place the seatback in a non-passenger position when the slider is within the tilt-and-slide region, and causes the recliner to place the seatback in a passenger position when the slider is within the detent region.

A vehicle seat is provided herein. The vehicle seat includes a cushion disposed within a seating member having at least one inflatable first bladder for selectively adjusting the firmness of the cushion. An inflatable second bladder is separated from a support surface of the seating member by the first bladder and fluidly connected to the first bladder. A vehicle seat hip pivot point is maintained when adjusting the firmness of the cushion by increasing the pressure in the second bladder when the pressure in the first bladder is selectively decreased, and by decreasing the pressure in the second bladder when the pressure in the first bladder is selectively increased.

A power seat slide device capable of changing not only to an electric operation but also to an manual operation, and preventing half-lock in spite of a manually operable structure. For front-rear movement, a rack attached to a lower rail and a pinion meshed with the rack are used, and a driving force of a motor is transmitted to the pinion, which enables the use in an electric mode. As no slide screw is used, while the motor is not energized, rotating the pinion causes an output shaft of the motor to rotate, so that manual adjustment becomes possible.

In a seat reclining device, a seatback frame forming a skeleton of a seatback is coupled to a seat cushion frame to be rotatable about a shaft with respect to the seat cushion frame. One end portion of a first sliding bracket is rotatably coupled to a middle portion of the seatback frame by a driving unit. The other end portion of the first sliding bracket extends toward a vehicle body located behind the seatback. A second sliding bracket is mounted on the vehicle body located behind the seatback and extends toward the first sliding bracket in a front and rear longitudinal direction to be connected to the first sliding bracket. The second sliding bracket is configured to guide a sliding movement of the first sliding bracket while the first sliding bracket is being rotated.

A seat cushion adjuster in one aspect of the present disclosure comprises at least one bracket, at least one slider, and a plurality of interposing members. The plurality of interposing members is disposed between an inner wall of the at least one bracket and the at least one slider so as to interpose the at least one slider among the plurality of interposing members in an inner hollow portion of the at least one bracket. At least one interposing member of the plurality of interposing members comprises at least one supporting protrusion portion protruding toward the at least one bracket.

Disclosed is a seat for a vehicle configured to variously adjust a seat position between, for example, a full-flat mode, a relaxation mode, a cushion tip-up mode, a full-bed mode, a walk-in mode, and a rear-view mode using a first hinge shaft to rotate the entire seat, including a seatback and a seat cushion, and a second hinge shaft to rotate the seatback.

A recliner heart includes first, second and third locking plates and a pawl. The first locking plate defines a recess. The second locking plate includes a first inner diametrical surface having first teeth formed thereon. The third locking plate is disposed between the first and second locking plates and includes a second inner diametrical surface and an outer diametrical surface. The second inner diametrical surface has a notch formed therein. The outer diametrical surface has second teeth formed thereon. Some of the second teeth are meshingly engaged with some of the first teeth. The pawl is slidably disposed in the recess between a secure position in which the pawl is engaged with the notch of the third locking plate and a release position in which the pawl is disengaged from the notch of the third locking plate.
