Siège avec un dossier pour un véhicule automobile

The seat backrest (22) has padding (28) with a shoulder section (40) near the head restraint (32), which has normal flexibility under normal conditions in the vehicle, and when under load by the back of the passenger. During accident-dependent acceleration of the vehicle above a threshold value, the padding has considerably increased flexibility, so that the shoulder section behind the passenger back is considerably thinner than normal, e.g. min. 30mm, pref. 40mm thinner than normal.
