Child protection system for motor vehicles

Abstract

A child protection system comprises a back rest, a back support on the seat back, a head rest component of the back rest which is displaceably mounted on the back support, a first adjusting mechanism which is used to adjust the position of the head rest component in relation to the back support in the longitudinal direction of the back, two lateral shoulder support flanges which are arranged in a transversal manner in the longitudinal direction of the back and at a distance from each other on the lateral support section of the head rest component, and a second adjusting mechanism which is used to adjust the distance between both lateral shoulder support flanges in a transversal manner to the longitudinal direction of the back. A coupling mechanism is configured such that during actuation, one adjusting mechanism as well as the other adjusting mechanism is triggered.
