Described are adjustable seats having a lower portion of a back rest attached to a seat frame having an upper frame and a lower frame. A pivot axis is positioned at an upper end of the lower portion of the back rest, and an upper portion of the back rest is pivotally attached to the pivot axis. The location of the pivot axis is configured to be positioned below a person's shoulders when the person is seated in the adjustable seat. The upper portion of the back rest is also pivotally adjustable relative to the lower portion of the back rest. A seat pan having a front portion pivotally coupled to a rear portion can be attached to the upper frame. An actuation mechanism is configured to simultaneously control a vertical height of the upper frame and a rotational position of the front portion of the seat pan.

A vehicle seat includes: a seat frame that serves as at least a portion of a skeletal structure; a fixed bracket that is fixed on the indoor wall, the fixed bracket including a connection part having a connection surface that is substantially orthogonal to a seat width direction and extending in a substantially vertical direction; a link member in which one end is swingably connected with the connection part and the other end is connected with the seat frame, the link member being swingable in a direction substantially parallel with the seat width direction set as a swinging center axis; and a regulation part which extends from the connection part in a direction substantially parallel with the swinging center axis, the regulation part being configured to regulate, by abutting on the link member in the seat front-and-rear direction, that the link member swings beyond a preset swinging range.

The disclosure relates to a seat trim structure for a vehicle seat with at least a mounting element having a plurality of integrated retaining elements, a number of detachable support members, and a number of detachable trim elements. The support members may be detachably arranged to the mounting element and the integrated retaining elements may be configured to detachably retain the number of trim elements to the mounting element.

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.

A vehicle seat control apparatus is equipped in a vehicle capable of travelling by automated driving and is configured to set a position and attitude of a seat of the vehicle to a driving position in low automated driving and to set the position and attitude of the seat to a relaxing position in high automated driving. The vehicle seat control apparatus includes an alertness detecting device configured to detect an alertness level of a driver seated on the seat, a computation control device configured to drive the seat driving device to perform an alerting operation if the alertness level is lower than a predetermined level when driving of the vehicle transitions from the high automated driving to the low automated driving, and a seat driving device configured to displace the seat at a higher speed than at a transition from the driving position to the relaxing position.

A conveyance seat accommodable in a recess of a floor includes: a seat cushion; a front leg portion which supports a front lower portion of the seat cushion and of which one end is rotatably fixed at the front lower portion of the seat cushion and the other end is detachably fixed at a position in front of the recess; a rear leg portion which supports a rear lower portion of the seat cushion and of which one end is rotatably fixed at the rear lower portion of the seat cushion and the other end is rotatably fixed to the floor inside the recess; and an arm portion of which one end is rotatably fixed to the rear leg portion and the other end is fixable to the floor at a position behind the other end of the rear leg portion.

Proposed are a vehicle seat monopost assembly and a vehicle seat mounted thereon. In one aspect, a drive part includes a housing mounted on a lower frame connected to a vehicle body and a first engagement part configured to be rotated by a drive source. A second engagement part suitably may include a thread configured to be engaged with the first engagement part and a cylindrical body configured to be fixed to a vehicle seat frame. A connecting sleeve part is seated on the drive part and has an inner space into which the lead screw part is fitted. The connecting sleeve part is configured to restrict a rotation in response to an operation of a rotation restricting member.

A connecting element (3) for adjusting the height of a vehicle seat (1) includes an angular element (3.1) with a first leg (3.1.1) having a seat part side receiving opening (3.1.5) and an opposite rail side end receiving opening (3.1.4), and a second leg (3.1.2) angled relative to the first leg (3.1.1) and a tooth element (3.2). The seat part receiving opening (3.1.5) is situated in a connection area of the first leg (3.1.1) and of the second leg (3.1.2). The tooth element (3.2) has a first section (3.2.1) configured as a circular arc with toothing (V2) that is connected at an end side to the second leg (3.1.2) and a second section (3.2.2) that is angled from the first section (3.2.1) in the direction of the receiving opening (3.1.5) on the side of the seat part and is connected to the first leg (3.1.1) at the end side.

A locking apparatus of a buckle of a seat belt for vehicles includes a sector gear bracket configured to be integrally coupled to a rear pipe which is coupled to a seat cushion frame, wherein the sector gear bracket has: an arc-shaped locking hole; and a sector gear arranged along the locking hole as an internal gear; a pole bracket located at one side of the sector gear bracket, wherein the pole bracket has a shaft part which is configured to pass through the locking hole and the seat cushion frame and then be integrally coupled to a lower end of the buckle; and a lock gear arranged on the pole bracket as an external gear.
