A system and method for determining whether a passenger is seated in a seating area and, based at least in part on detecting the passenger, engaging or disengaging a flap in a headrest. Such a headrest may span multiple seats so that a single headrest is used by multiple passengers. Each of one or more flaps in the single headrest may then be configured by the passenger to provide each passenger with their own privacy and comfort. By actively controlling the state of the flap, a uniform passenger experience may be created so that the flap is in the same state upon a passenger entering the vehicle. Further, examples of the headrest are designed and configured to couple directly, or indirectly, to a vehicle body, such that the headrest does not couple directly to a seat or passenger seating area.

An adjustment mechanism for a seat comprises at least one screw shaft (111, 112) and a motor for driving the at least one screw shaft (111, 112). Further, the adjustment mechanism comprises at least one nut element (121, 122) engaged with the at least one screw shaft (121, 122) in such a way that a rotation of the at least one screw shaft (111, 112) caused by the motor translates into a linear motion of the at least one nut element (121, 122). In a first range of the linear motion of the at least one nut element (121, 122) the linear motion translates into adjustment of the seat according to a first degree of freedom, and in a second range of the linear motion of the at least one nut element (121, 122) the linear motion translates into adjustment of the seat according to a second degree of freedom.

A reversible seat for an automotive vehicle having a head restraint which rotates between a forward-facing position and a rearward-facing position as the seat is moved between the forward-facing position and the rearward-facing position. The head restraint folds towards the seat back as the reversible seat passes through the peak of its locus to increase clearance with a headliner of the automotive vehicle. The head restraint returns to an upright rotated position as the seat reaches the opposing position.

A vehicle seat includes a headrest body provided at an upper portion of a seat back rotatably supported by a seat cushion on which an occupant is seated. The headrest body is covered with a skin material. The headrest body includes a driving body that is configured to form a swelling portion that is a portion of the skin material in a seat-height direction swelling toward a front side of the seat at a surface of a seat front side of the skin material and change a formation position of the swelling portion in the seat-height direction by being operated inside the headrest body.

A child car seat includes a seat bottom, a backrest extending upwardly from the seat bottom, and a movable headrest mounted to be moved on the backrest. The child car seat also includes a controller for changing the elevation of the movable headrest relative to the underlying seat bottom.

Provided is a simple and compact headrest support device. The headrest support device (20) comprises a support member (22) coupled to a frame (2) of a seatback (1), and a headrest pillar structure including a pillar base portion (25) extending laterally and supported by the support member so as to be rotatable around an axial line of the pillar base portion, and a pair of pillar main body portions (26) extending substantially vertically from the pillar base portion substantially in parallel to each other in a laterally spaced apart relationship and connected to a headrest (24), wherein the support member is coupled to the frame at at least one coupling portion (34) disposed between the two pillar main body portions in front view in a headrest upright condition where the headrest is positioned above the seatback.

The invention relates to a headrest, in particular for a vehicle seat, with a head contact part (11), with a support (12) for mounting the headrest (10) on a fixed structure, with at least one parallelogrammatic linkage (23) between the head contact part (11) and the support (12) that carries the head contact part (11) for movement relative to the support (12) between a first position and a second position, wherein the parallelogrammatic linkage (23) comprises at least two links (16, 17), and each link (16, 17) forms at least one pivot joint (G1A, G2A, G1C, G2C) with the support (12) and at least one pivot joint (G1B, G2B, G1D, G2D) with the head contact part (11), with a latch (19), with a first latch formation on the support (12) and a second latch formation on the head contact part (11), wherein the first latch formation and the second latch formation are in engagement in a locked position and are disengaged in a release position. The special feature is that the first latch formation is fixed on the support (12) or that an upper region of at least one link (116) is provided with the first latch formation, and that the second latch formation is fixed on the head contact part (11).
