An active noise cancellation system (1) for cancelling environment noise perceived by a driver or passenger seated in a seat (3) mounted in a cabin of a vehicle, in combination with said seat, the seat comprising a seat cushion (19), a seat back (21) coupled to the seat cushion at a bottom end and extending upwards to a seat shoulder (23), and a headrest (22) coupled to the seat back, extending upwardly from the seat shoulder, the active noise cancellation system comprising an active noise cancellation circuit (ANC) (30), a plurality of microphones (10) mounted in the headrest and connected electrically to the ANC, and a plurality of speakers (16) mounted in the seat and connected electrically to the ANC circuit. The plurality of microphones comprises at least one first microphone mounted on a right side of the headrest and at least one second microphone mounted on a left side of the headrest, and the plurality of speakers comprises at least one first speaker mounted in the seat shoulder on a left side and at least one second speaker mounted in the seat shoulder on a right side, the right speaker configured to generate a noise cancellation sound from a noise signal picked up by the right microphone processed by the ANC circuit and the left speaker configured to generate a noise cancellation sound from a noise signal picked up by the left microphone processed by the ANC circuit.

A measurement device for a vehicle seat includes a memory; a processor coupled to the memory; a headrest body of a headrest; a first side section of the headrest that is swingable toward a seat front side so as to support the neck of the vehicle occupant; a second side section of the headrest that is swingable toward the seat front side so as to support the neck of the vehicle occupant; a first electrode provided at the first side section and contacting the neck in a state in which the first side section is supporting the neck; and a second electrode provided at the second side section and contacting the neck in a state in which the second side section is supporting the neck. The processor is configured to acquire a waveform of a potential difference based on the potential difference between the first electrode and the second electrode over time.

An equipment part with a base and at least one pivot device, which is pivotable about a pivot axis relative to the base, with a drive device with which the pivot device is pivotable between a first position and a second position. The pivot device includes a base part and an extension part, wherein the extension part is guided movably relative to the base part in a translatory manner between a primary position and a secondary position. Associated with the base is a first support surface that engages with a second support surface, which is associated with the extension part, and rolls on this during the pivoting movement between the first position and the second position, wherein the extension part moves between the primary and the secondary position.

An equipment part for a vehicle, including a wing device having at least one wing. The wing is pivotably about a pivot axis between a first pivot position and a second pivot position. The wing has a base part and an extension part that is supported movably relative to the base part in a translatory manner between a base position and an extended position. An adjusting device has at least one motor drive and a transmission for executing the pivoting movement as well as the translatory movement of the wing. By way of the transmission, a conversion takes place of a rotary movement of the drive to a translatory movement of the extension part, wherein a torque about the axis of rotation is produced in the base part, with which torque the wing is pivotable between the first pivot position and the second pivot position.
