Various implementations include seats and related systems for detecting user proximity and controlling one or more functions based on that proximity detection. In particular cases, the seats include capacitive sensors for detecting user proximity. In some particular aspects, an automobile seat includes: a core section; a cover over at least a portion of the core section, the cover having a set of capacitive sensors across a front of the seat; and a processor for processing signals from the set of capacitive sensors to detect a proximity of a user.

An integrated car seat ear buds device including a pair of Bluetooth ear buds, a control unit and a pair of retractable wiring cords. The pair of Bluetooth ear buds are integrated within the headrest region of the car seat. The control unit controls the operation of the Bluetooth ear buds. The pair of retractable wiring cords are embedded within the headrest of the car seat. The pair of retractable wiring cords are configured to retract into the headrest, in a default position, and upon a first manual manipulation of the pair of retractable wiring cords and are configured to extend outwards from the headrest upon a second manipulation of the pair of retractable wiring cords. Each Bluetooth ear bud is attached to a distal end of a corresponding retractable wiring cord.

A device for ventilating the occupant of a vehicle seat, comprising an air inlet receiving air from a ventilation member, and comprising a first duct integrated at least in part into the backrest of the seat, a second duct integrated into a headrest mounted on the seat and supplying at least one air outlet integrated into the headrest and expelling air coming from the ventilation member, the second duct and first duct being connected by a leaktight sliding connection.

An ultraviolet (UV) light shield system includes multiple UV lamps mounted within an internal cabin of a vehicle. The UV lamps are positioned to emit UV light in fields of illumination that extend along sides of passenger seats disposed within the internal cabin. Two adjacent fields of illumination are spaced apart to define a protection zone for a passenger sitting on one of the passenger seats.

A headrest sleeve for assembly to a bracket fixed to a stay for supporting a main body of a headrest. The headrest sleeve includes a sleeve body formed in a tubular shape, a collar-shaped flange extending from one end portion of the sleeve body and disposed so as to be capable of contacting the bracket, a bracket-fitting section extending from the flange toward an opposite side from the sleeve body and configured to be capable of being fitted into a fitting hole formed in the lower bracket, and an anchor clip provided at the bracket-fitting section and configured to undergo elastic deformation and elastic recovery during the fitting of the bracket-fitting section into the fitting hole so as to engage with the bracket from an opposite side from the flange.

The time required to complete current-to-target state transitions of a plurality of movable portions constituting a seat is shortened. A seat unit 1 includes an occupant support portion S1, a plurality of movable mechanisms respectively moving a plurality of parts constituting the occupant support portion S1, and an ECU 40 controlling respective operations of the plurality of movable mechanisms. The ECU 40 causes each of the plurality of movable mechanisms to undergo a transition from a current state to a target state and the plurality of movable mechanisms have a first movable mechanism requiring a longest time for the transition. The ECU 40 causes the transitions of the plurality of movable mechanisms other than the first movable mechanism to be completed by completion of the transition of the first movable mechanism from the current state to the target state.

Various implementations include seats and related loudspeaker assemblies. In particular cases, a seat includes: a seat headrest portion; a seat backrest portion; and a loudspeaker assembly associated with the backrest portion. The loudspeaker assembly can have an acoustic directivity angled upward above a nominal ear position of an occupant.
