A vehicle seat is provided. The vehicle seat comprises construction elements that are movable relative to one another and at least one force transmission element which transmits activation forces and/or stress forces that result from the use of the vehicle seat from one construction element to the other. The force transmission element by way of at least one joint is connected to both construction elements, and conjointly with the at least one joint is an integral component part of at least one of the two construction elements.

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 headrest, for a vehicle seat, is reversibly transferable between a first latching position and a second latching position by a translation movement. The headrest has a shaft co-rotating with the translation movement. The shaft is connectable in the first latching position and in the second latching position to a latching element. The latching element is connected to the shaft via an elastic component. A system for forming an alignment device which can be integrated in a headrest is further provided.
