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).

A seat device for a vehicle includes a dynamic damper attached to a frame of a seat installed in the vehicle. The dynamic damper includes a damper case that is formed from separable first and second case halves, a weight that is housed in a damper chamber, and an elastic member that is disposed between the weight and the damper chamber so as to allow vibration of the weight. The damper case is provided with a plurality of mounting parts that are mounted on the frame, and the mounting parts comprise first and second mounting parts which are engaged with the frame at two left and right places as seen in a front view of the seat, and a third mounting part other than the first and second mounting parts which is provided between the first and second mounting parts.

An autonomous can include one or more configurable passenger seats to accommodate a plurality of different seating configurations. For instance, the one or more passenger seats can include a passenger seat defining a seating orientation. The passenger seat can be configurable in a first configuration in which the seating orientation is directed towards a forward end of the autonomous vehicle and a second configuration in which the seating orientation is directed towards a rear end of the autonomous vehicle. The passenger seat can include a seatback rotatable about a pivot point on a base of the passenger seat to switch between the first configuration and the second configuration. Alternatively, or additionally, the autonomous vehicle can include a door assembly pivotably fixed to a vehicle body of the autonomous vehicle such that a swept path of the door assembly when moving between an open position and a closed position is reduced.

A headrest (1) for a vehicle has a headrest body (1.1). The headrest body (1.1) has a substantially C-shaped cross section. A holder (5), for holding at least one object (3), is arranged inside a hollow space (H) enclosed by the C-shaped cross section. The holder (5) is integral with the headrest body (1.1) and is formed by a molded portion, or several molded portions, of the headrest body (1.1), and/or by at least one mechanically flexible portion of the headrest body (1.1). The headrest body (1.1) is thereby configured such that the object (3) can be retained by a clamping between the limbs of the C-shaped cross section.

A headrest mountable neck rest assembly for securing a neck rest to a headrest includes a neck rest that includes a middle portion, a first outward portion and a second outward portion wherein the middle portion is positioned between the first and second outward portions. A securing member is attached to and extends away from the neck rest. The securing member releasably engages a headrest of a seat. A cushioning member is removably positioned on the securing member and cushions an interaction between a person's head and the securing member.

Apparatus (10) for a vehicle seat, the apparatus (10) comprising a first supporting means (12) and a second supporting means (14), the first supporting means (12) comprising a storage means (16) and the second supporting means (14) being a headrest comprising a cover (18) for covering the storage means (16), the headrest being arranged to have a deployed condition and a retracted condition, wherein in the deployed condition the storage means (16) in the first supporting means (12) is at least partially uncovered, and in the retracted condition the storage means (16) in the first supporting means (12) is covered by the cover (18).

The technology described in this document can be embodied in a headrest of a seat, the headrest including an enclosure for housing one or more acoustic transducers, and an adjustable headrest wing disposed in front of the enclosure. The headrest wing is coupled to the enclosure by a pivot, and configured to be adjusted to one of multiple positions within an angle range around the pivot. The headrest wing is also configured to support the head of a seat-occupant. The headrest further includes a connector disposed between the enclosure and a rear portion of the headrest wing. The connector is configured to provide an acoustic channel between the enclosure and the headrest wing such that audio signals from the one or more acoustic transducers are radiated outward through the headrest wing.

A head rest assembly for a vehicle seat, the head rest assembly comprising a head support portion, a neck support portion and a pair of connection members adapted to connect the head rest assembly to the vehicle seat, wherein at least one of the pair of connection members is adapted for movement relative to the other of the pair of connection members so as to adjust a distance between the pair of connection members.
