Title
(EN) Adjustable cross-divided backrest for vehicle seat
Abstract
(EN)

An adjustable cross-divided backrest for a vehicle seat having of a lower backrest part which is mounted for swivel movement on a lower seat frame in an axis running across the travel direction, and an upper backrest part fixed so that it is displaceable on the lower backrest part, wherein the upper backrest part has an area supporting the head. The backrest is characterized in that the upper backrest part is both height adjustable and able to swivel relative to the lower backrest part, wherein the areas of the shoulder support and head rest are integrated in one piece in the upper backrest part. The lower backrest part has an upwardly directed projection in the area of the user's spinal column which can engage in a matching downwardly open recess of the upper backrest part. This projection of the lower backrest part substantially fills out the recess when the upper backrest part is located in its lowermost height adjustment position.
