<p>In order to improve safety of passengers having various anthropometric characteristics, an automobile seat is foreseen, which is furnished with automatically height adjustable head rest (4), wherein such seat comprises a seat frame (1), a rest frame (2), a guiding assembly (3), a head rest (4) as well as a transmission assembly (5), which is designed in such manner that each forward or rearward displacement of the seat frame (1) relatively to each corresponding guide (31) of said guiding assembly (3) is by means of appropriate transmission elements (51, 52, 53, 54) transferred into the area of placing the head rest (4) onto the rest frame (2), namely by means of at least one flexible transmission element (51, 52) and at least one compensating assembly (53, 53', 53", 54) and/or at least one transmission ratio transforming element (55) which is used for the purposes of reducing or multiplying said displacement, by which simultaneously with performing each desired displacement of said seat frame (1) relatively with respect to said guide (31) each corresponding displacement of the head rest (4) relatively to the rest frame (2) is obtained having however different length and/or time dependency than the previously mentioned displacement of the seat frame (1) relatively to the guide (31 ).</p> |
