A vehicle seating assembly including a lower seatback. An upper seatback is operably coupled to the lower seatback. The upper seatback is pivotally mounted to the lower seatback at a pivot axis. An arcuate back support bar is disposed in the upper seatback and is configured to rotate the upper seatback between forward and rearward positions. The arcuate support bar includes first and second generally linear members and an arcuate intermediate portion disposed between the first and second generally linear members. An articulation assembly operably couples the lower seatback with the upper seatback.

A vehicle seat that accommodates at least two users includes a seating portion frame, a first backrest and a second backrest which are pivotally hinged to the seating portion frame according to a transverse axis, via a common hinge. The common hinge includes: a pivot pin comprising a first lateral portion, and a first housing arranged on the first backrest and receiving interiorly the first lateral portion by authorizing the rotation of the first backrest. The first lateral portion has a protruding rib and the first housing has a substantially keyhole shape, complementary with the radial section of the first lateral portion. The rib is oriented, according to an angle of between 30° and 60° relative to the vertical direction of the vehicle seat.

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 vehicle seat includes a main part that forms a center portion of a front surface of a seatback; bolster parts that form side parts of the front surface of the seatback; and a reclining adjuster configured to adjust a backrest angle of the seatback, and to move a lower area of the main part toward a front side relative to the bolster parts as the main part is reclined.

The invention relates to a vehicle seat comprising a seat part and a backrest, the backrest comprising at least one left-hand backrest longitudinal support extending in the vertical direction of the backrest and at least one right-hand backrest longitudinal support extending in the vertical direction of the backrest, the backrest longitudinal supports being attached to the seat part and/or a seat-part frame in a lower end region and comprising at least one cushion element, wherein the length of a distance between the backrest longitudinal supports can be adjusted by means of at least one elongate backrest cross strut arranged in the upper region of the backrest.

Provided is a vehicle seat that has a relatively simple structure and can hold passenger's scapulae and surrounding body area even when the angle of the backrest is tilted down. A vehicle seat includes: a seat cushion forming a sitting surface of the seat; and a seat back provided at a back of the seat cushion and serving as a backrest of the seat, the seat back including: a first tippable portion provided so that an angle of the seat back to a seat frame forming a framework of the seat is adjustable; and a second tippable portion pivotally provided at an upper side of the first tippable portion, wherein when the first tippable portion is tipped toward a rear of a vehicle, the second tippable portion abuts against a projecting portion provided at the seat frame and is thus protruded from the first tippable portion.

A vehicle seat includes: a chamber in which at least a seat-front-surface side is covered with a pad and which circulates the air blown from a front surface of a seat through the pad; a fan configured to send air into the chamber; and a support body which supports the chamber so as to be able to sink in an acting direction of a load applied to the surface of the seat. The chamber includes a first region and a second region, and the first region and the second region are configured to allow subduction of the chamber independently of each other.

A passenger seat (10) with a sitting area (40), a side ottoman (42), an open space (44) that may be enclosed via use of a bed extension (50), and a backrest (14). The backrest may be divided into an upper portion and a lower portion. The seat may also be provided with one or more storage areas and/or a side console.

A vehicle seat structure for a vehicle seat may have a structural component having an inertia belt reel. The inertia belt reel may be arranged in a cavity of the structural component, and the structural component may be connected to at least one further component of the vehicle seat structure. A method for assembling such a vehicle seat structure may include providing a structural component having an inertia belt reel and at least one further component of the vehicle seat structure that are displaced and/or rotated relative to one another such that the structural component and the at least one further component of the vehicle seat structure take up an end position with respect to one another. In a further step, the structural component and the at least one further component of the vehicle seat structure are connected to one another in a form-fitting and/or integrally bonded and/or force-fitting manner.

An occupant support a seat bottom and a seat back. The seat back includes a backrest including and an upper-back adjuster coupled to the backrest at least partially movable between a retracted position and an extended position. The occupant support is at least partially covered in an outer trim including a backrest portion and an adjuster portion that moves relative to the backrest portion. The outer trim blocks view of an interior of the seat back.
