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.

The present disclosure relates to the brake device of the power swivel seat that ensures to have no clearance in the rotational direction during operation of the swivel seat, resulting in improved stability of the operation, and minimized generation of operating noise. Disclosed is a brake device of a power swivel seat including: a brake ring connected to a swivel fixing part; a brake wedge connected to a swivel rotating part; a brake roller and a brake spring installed in a wedge space formed between an inner circumferential surface of the brake ring and an outer circumferential surface of the brake wedge; and an unlocking block installed to rotate the brake wedge in a direction allowing to release lock caused by the brake roller in the wedge space.

A control armrest containment structure includes a seat assembly positioned at an end of a seat in a vehicle and an armrest assembly fastened to the seat assembly. The armrest assembly includes a fixed unit fixed to an end of the seat assembly, a movable assembly fastened to an end of the fixed unit and configured to move up and down along the fixed unit, and a rotary unit fastened to an end of the movable unit and configured to rotate with vertical movement of the movable unit.

Provided is an automatic pop-up device for a vehicle legrest having the following effects. A seatback reclining mechanism, a tilting mechanism, and a legrest deployment mechanism are formed as a simple integrated mechanism configured to adjust a relaxation position of a passenger, and the integrated mechanism allows the legrest to be automatically deployed when a reclining operation of a seatback and a tilting operation of a seat cushion are performed together, thereby reducing the number of components, costs, and weight. Additionally, provided is a single switch configured to adjust the relaxation position of the passenger, thereby improving the convenience of a switch operation of adjusting the relaxation position of the passenger.

The present invention relates to an inbuilt seat leg support and a seat. The seat leg support is mounted in a seat. The seat includes a base frame and a cushion frame located above the base frame. A receiving space is formed between the base frame and the cushion frame. The seat leg support includes a leg support frame configured to be received in the receiving space. The leg support frame is movable and adjustable relative to the cushion frame. Movement and adjustment of the leg support frame cause the leg support frame to extend out of the receiving space to be in an extended state or to retract into the receiving space to be in a received state. According to the present invention, a receiving space for a leg support frame is reserved between a base frame and a cushion frame, and the leg support frame is disposed to be movable so that the leg support frame can be received in the receiving space when not in use. Receiving a leg support in a seat causes the present invention to be space-saving.

A power long rail assembly is attached to a vehicle floor for repositioning vehicle seats in a vehicle between a plurality of seating positions. The power long rail assembly includes a fixed long rail and a power rail drive assembly configured to travel along the fixed long rail. The power rail drive assembly has an upper channel having a driving wheel configured to frictionally and/or meshingly engage with the fixed long rail, a fore/aft motor operatively coupled to the driving wheel, a latch assembly for locking the upper channel to the fixed long rail, and a latch release mechanism having a latch motor operatively coupled to a release plunger for automatically unlocking the latch assembly from the fixed long rail, and a fore/aft button operatively coupled to the fore/aft motor and to the latch motor to selectively activate the fore/aft motor and the latch motor.

A vehicle seat includes a seat bottom coupled to floor of a vehicle and a seat back coupled to the seat bottom to move relative to the seat bottom. The seat back includes a backrest and a backrest adjuster configured to move relative to the backrest to change a shape of the backrest.

A seat assembly includes a cushion motor linked to a pinion gear for providing concentric rotation of a linkage through rotational engagement of the pinion gear with a sector gear. The seat assembly includes a seat back pivotally coupled to a seat cushion and a seat base adapted for mounting the seat assembly within an automotive vehicle. The linkage includes a front link and a rear link extending between the seat cushion and the seat base, wherein pivoting of the linkage moves the seat assembly between a plurality of positions. A recliner mechanism is operatively coupled to the front link for selectively allowing pivoting thereof, and the sector gear is fixed to the front link. Actuation of the cushion motor when the recliner mechanism is unlocked rotates the pinion gear, causing the sector gear to rotate for pivoting the linkage to move the seat assembly between the plurality of positions.

A gear drive (12) with a first gear (10) which has first tooth flanks (26), and a second gear (30) which has second tooth flanks (32) and which engages with the first gear (10), the first gear (10) having a tip circle (14) with a tip circle radius (16), a root circle (18) with a root circle radius (20) and a modification circle (22) with a modification circle radius arranged between the tip circle (14) and the root circle (18). (24), wherein the first tooth flanks (26) between the root circle (18) and the modification circle (22) each have a recess (28) in such a way that, when the gears (10, 30) mesh, there is no contact between the first tooth flanks (26) and the second tooth flanks (32) between the root circle (18) and the modification circle (22), and a longitudinal seat adjustment for a motor vehicle with a gear drive (12).

A lumbar support for a vehicle seat includes: a support panel made of an elastic material and supporting the user's lumbar vertebra; a first guide rod supporting the support panel; a second link bracket fastened to the first guide rod to be movable up and down; a first link bracket disposed under the second link bracket to be movable up and down with respect to the second link bracket, and having an operation block providing a supporting force to the lumbar vertebra; a first rotary screw vertically extending, thread-fastened to the first link bracket, and moving up and down the first link bracket by rotating about a longitudinal axis; and a second rotary screw vertically extending, thread-fastened to the second link bracket, and moving up and down the second link bracket by rotating about a longitudinal axis.
