ABSTRACT:
Backrest for a vehicle seat with a height-adjustable headrest, which is adjusted by support rods guided inside the backrest frame, and which has ends of the support rods connected to one another by a crossbar having one or more radially biased retaining elements for retaining an end of one of the support rods, and a locking element provided for restricting movement of the retaining element. During assembly of the automobile seat, before upholstering, one of the stop-lock connections located between the support rods and the crossbar is locked by pushing a locking element up on the outside of the retaining element. The stop-lock connection is thus “frozen” to a certain extent. Once manufacturing of the automobile seat is completed, this stop-lock connection can be disengaged only by partially removing the upholstery, which for practical purposes excludes a removal of the headrests for day-to-day driving.
