Aspects of the disclosure relate to vehicles capable of autonomous driving. These vehicles may include seats for accommodating different numbers of passengers. In some cases, the seats may be reconfigurable. For instance, a vehicle may include a first row of seating having a first, passenger use configuration. The first row may allow a passenger to sit in a seat of the first row of seating and access user input controls for the vehicle. The first row of seating may also have a second, folded configuration where the first row is in a folded configuration and no longer usable for passenger seating. The vehicle may also have a second row of seating. When the first row of seating is in the second, folded configuration, the second row of seating may still be usable for seating and may include additional legroom for the passenger as compared to when the first row of seating is in the first passenger use configuration.

The present invention relates to a headrest folding device, more particularly, to a headrest folding device wherein a ratchet is connected between a release lever and a lock link which maintains the unfolding (upright) of a headrest, so that the operation of the release lever is not directly transferred to the lock link, but rather indirectly transferred to the lock link through the ratchet, thereby smoothing the operation of the release lever.

A headrest assembly having at least one articulated cushion section that is deployable from a recess in a stowed position, a passenger seat comprising the headrest assembly and cushion section, as well as vehicles comprising the seat, and methods of installation are disclosed.

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.

A vehicle seating arrangement includes first and second seating assemblies that are each equipped with a seat and a seatback. A surface of the seat of the first seating assembly is vertically above a surface of the seat of the second seating assembly. A forward extreme of the first seating assembly is displaced rearward of a forward extreme of the second seating assembly.

A seat is provided in which a seat cushion is pivotally coupled to a seat back by a recliner assembly. The recliner assembly is selectively operable between a locked condition preventing pivotal movement of the seat back and an unlocked condition allowing pivotal movement of the seat back. A riser assembly supports the seat assembly above a floor, such as the floor of a vehicle, and is configured for actuation and movement of the seat assembly between a generally upright seating position, a pitched easy entry position tilted forwardly and downwardly towards the floor to allow easier ingress and egress behind the seat, and a stowed position recessed within a compartment below the floor.

A seat assembly with an adjustable head restraint assembly capable of being adjusted based on an approximate stature or spatial location of an occupant in the seat assembly. A seat assembly may include a sensor in the seat to detect if an occupant is present. The sensor may include a plurality of bladders and pressure sensors, a radar system, or a neuro-monitoring sensor. The sensor may send a signal to a controller indicating the presence of an occupant. The controller may approximate the size and/or spatial location of the occupant and send an adjustment signal to the head restraint adjustment mechanism to adjust the head restraint assembly to an in-use position. The controller may determine that an occupant is not present and send an adjustment signal to the head restraint adjustment mechanism to adjust the head restraint assembly to a non-use position.
