摘要

The vehicle seat has a backrest outer frame (2), and a backrest inner frame (7) with the fitted backrest (11) and head support (10), which is mounted at the outer frame by lower (5) and upper (12) linkages. On a rear impact, the seated person is pressed against a lower impact zone (15) of the backrest, and the inner frame swings from a normal position at the outer frame into a crash setting and the headrest moves forwards and upwards. At least one linkage is a clip so that, on a rapid return movement from the crash setting, the inner frame is clamped against the outer frame.
