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.

The load applied to a connecting member that connects a second horizontal shaft to a base member in a headrest for a vehicle is reduced. The headrest comprises a pillar member including a right and a left vertical shaft extending upward from an upper part of a seat back, a right and a left first horizontal shaft extending forward from upper ends of the respective vertical shafts, each first horizontal shaft including a curved section, and a second horizontal shaft extending laterally between front parts of the first horizontal shafts, a base member including a base vertical portion extending vertically ahead of the vertical shafts, a base upper portion extending rearward from an upper end of the base vertical portion, and a right and a left first hole formed in the base upper portion to have the respective curved sections or the respective vertical shafts passed therethrough, a connecting member pivotably connecting the base upper portion to the second horizontal shaft, and a pad supported by the base member.

A headrest structure for a passenger seat, a headrest cushion and passenger seat. The headrest structure comprises an adjustable headrest frame for connection to a passenger seat; and a headrest cushion mounted to the adjustable headrest frame such that the headrest cushion is moveable relative to a seat back of the passenger seat by way of the adjustable headrest frame; wherein the headrest cushion comprises a support surface facing away from the headrest frame, the support surface comprising a concave upper part and a convex bottom part relative to the passenger seat.

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.

A head restraint for a vehicle seat, includes a central part having a front surface, an upper side and opposing side surfaces. First and second side parts are operably coupled to the opposing side surfaces of the central part and are operable between supporting and non-supporting positions relative to the central part. The first and second side parts each include first and second limbs which are flexibly coupled to one another, wherein portions of the first and second side parts protrude outwardly relative to the front surface of the central part when the first and second side parts are in the supporting position.

In a seat device for a vehicle, a dynamic damper comprises a damper case that is formed from first and second case halves joined together so as to be capable of separating from each other to define a damper chamber therebetween, a weight that is housed in the damper chamber, and an elastic member that is disposed between the weight and an inner face of the damper chamber so as to allow vibration of the weight, the damper case being provided with a mounting part that is mounted on a frame of the seat. Thus, it is possible to provide a seat device for a vehicle in which replacement of a weight and an elastic member in order to adjust or change the damping characteristics is possible, and the ease of mounting a damper case on a seat is good.

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.
