A reclining collar headrest with rotatable block ends
Реферат: The present invention concerns a headrest (1) comprising a central part (2) that assembles, on each one of its two sides, an arm (4) provided with an end (10). The two arms (4) are assembled in a rotatable manner with respect to the central part (2) between a lifted position, in which they result rotated towards the central body (2), and a lowered position in which they are rotated so as to be protracting externally from the central part (2) so that they can be placed on the shoulders of an underlying user and vice-versa In accordance with the invention, the ends (10) are rotatable with respect to the arm (4). Moreover, the headrest further includes rotation means (3, 5, 6, 7, 8, 9, 10') configured to cause a contextual rotation of the ends (10) in correspondence of an arm rotation (4) in such a way that, during a rotation towards the lowered position of the arm (4), each end (10) rotates contextually with respect to the arm (4) towards a block position for realizing a security constraint against the body of the user.
