Abstract: A child seat, in particular for a motor vehicle, has a seat-surface structure, which extends generally in a longitudinal direction and defines the seat surface, and a backrest. One part of the seat-surface structure can be adjusted and secured in the longitudinal direction relative to those remaining parts of the seat-surface structure which define the seat surface. A substructure that carries the seat-surface structure is operative so that the inclination of the seat-surface structure can be adjusted relative to the substructure. A belt-retaining device is carried by the backrest and operative in one operating mode to clamp the seatbelt, in response to the seatbelt traveling in a first pulling direction, and to release the seatbelt, in response to the seatbelt traveling in a second pulling direction. In another operating mode, the belt-retaining device loosely surrounds the seatbelt.

Abstract: A vehicle seat has a seat part and a backrest adjustable in inclination relative to the seat part. The backrest is configured in two parts, a top backrest part and a bottom backrest part. The top backrest part is arranged pivotally relative to the bottom backrest part, when the holding force of a clamping device is overcome in the case of a crash under the effect of an actuating force coming from the person in the seat. The top backrest part executes an adjustment movement intercepting the person in the seat. The vehicle seat improves the safety and security of the seat occupant upon a frontal crash or rear crash.
