The invention relates to a child safety seat () comprising an integral harness belt () for restraining a child in the child safety seat (), a belt tension monitor () adapted for monitoring a belt tension acting on the harness belt (), a motorized harness belt tensioner () comprising a tensioning element () driven by an electromechanical actuator () and adapted for adjusting the belt tension acting on the harness belt (), and a controller adapted for controlling the motorized harness belt tensioner () to adjust the belt tension to match a first predefined belt tension and for monitoring the resulting belt tension using the belt tension monitor ().

Child safety seat with a motorized harness belt tensioner

The invention relates to a child safety seat () comprising an integral harness belt () for restraining a child in the child safety seat (), a deflector () for the harness belt (), an elastic mechanism () adapted for forcing the deflector () from a first position () to a second position (), the harness belt () being guided by the deflector (), wherein due to the guidance by the deflector () the harness belt () length available for buckling in the child is shorter in the second position () than in the first position (), a latch mechanism transferable between a blocking position and a release position, the latch mechanism being adapted for blocking in the blocking position the deflector () against a movement toward the second position () and for releasing in the release position the deflector () for a movement induced by the forcing toward the second position (), a release mechanism adapted for transferring the latch mechanism from the blocking position to the release position upon receiving a trigger signal, and a force-transmitting element () coupled to a motion element (), the force-transmitting element () being adapted for transmitting a motion force from the motion element () to the deflector () that acts to force the deflector () from the second position () to the first position ().
