Description

Betr.: Verformbare Rückenlehne für Fahzeugsitze, insbesondere Kindersitze Die Oberkörper von Kindern in Auto-Kindersitzen sind zweckmäßig durch Schultergurte (Hosenträger- Kreuz-oder Diagonalgurte) zur Abstutzung gegen Verlagerung bei Kurvenfahrt oder Fahrverzögerung gehalten. Diese üblich starr mit dem Sitz verbundenen Gurtarten haben bei Aufprallunfällen den großen Nachteil, daß der Oberkörper des Kindes festgehalten wird, während der relativ schwere Kopf des Kindes weiter beschleunigt wird. Dadurch entsteht eine gefährliche Nickbelastung der noch schwach entwickelten Halswirbel. Die Neuerung dient dem Zweck, einem Kind zunächst während der Fahrt durch Schultergurte genügend Abstützung zu geben. Bei vorausberechneter Belastung sollen jedoch die Schultergurte energievezehrend nachgeben, damit Kopf- Nacken-und Rückenwirbel eine Ebene in der Beschleunigungsrichtung bilden können, um eine Nickbelastung möglichst auszuschalten. Diese Verlagerung des Oberkörpers ist bei den üblichen Platzverhältnissen im hinteren Fahrzeugraum bei Kindern bis zu 5 Jahren möglich.Re: Deformable backrests for vehicle seats, especially child seats The upper bodies of children in child car seats are conveniently supported by shoulder straps (Suspender, cross or diagonal belts) to support against displacement when cornering or driving delay held. These types of belts that are usually rigidly connected to the seat have the major disadvantage in impact accidents that the upper body of the child is held while the child's relatively heavy head continues to accelerate. Through this creates a dangerous nodding load on the still weakly developed cervical vertebrae. The purpose of the innovation is to initially support a child with shoulder straps while driving to give enough support. If the load is calculated in advance, however, the Shoulder straps give way in an energy-consuming way so that the head, neck and back vertebrae become one Can form plane in the direction of acceleration to avoid a pitching load as much as possible turn off. This shift of the upper body is with the usual space conditions possible in the rear of the vehicle for children up to 5 years of age.
