Headrest ( 5 ) for seats ( 10 ) of motor vehicles ( 4 ). It comprises a body ( 6 ) of essentially prismatic shape whose front face ( 11 ), which corresponds to the direction of travel of the vehicle ( 4 ), is adapted to receive, at rest, the back of the head of the occupant of said seat ( 10 ), whilst its rear face ( 12 ) faces the rear part of the vehicle's passenger compartment, the headrest ( 5 ) being provided with means ( 8 ) for its removable fastening to the seat ( 10 ) of the vehicle. The body ( 6 ) of the headrest ( 5 ) has coupled to it a communications module ( 7 ) adapted so as to link up, by means of radio waves, with a data-transmission unit ( 1 ), the communications module ( 7 ) being provided with at least one accessible screen ( 14 ) and acting as an interactive link with the data-transmission unit ( 1 ).
