<p>A headrest (1) for motor-vehicle seats comprising a yielding body (2) connected to a pair of supports (7), to be fixed to the backrest (S) of a motor-vehicle seat, through an articulated parallelogram system (4) formed by two pairs of swinging arms (5,6) by means of which the yielding body (2) can be displaced between a lowered position and a raised position. To hold the yielding body (2) in the raised position or, respectively, in the lowered position a locking system (30,33) is provided which, in the raised position of the yielding body (2), applies a retaining force appreciably higher than in the lowered position of the yielding body (2) and can be released by a push-button (26) arranged on one side of the yielding body (2). <IMAGE></p> |
