Abstract

A child safety seat includes a seat shell adapted to receive a child, a belt tightener and a latching mechanism. The seat shell defines a first and a second belt path, the first belt path being configured to receive an anchoring belt for attaching the child safety seat in a forward facing position on a vehicle seat, and the second belt path being configured to receive an anchoring belt for attaching the child safety seat in a rearward facing position on a vehicle seat. The belt tightener is pivotally connected with the seat shell, and is adjustable between a first position for clamping an anchoring belt disposed along the first belt path, and a second position for clamping an anchoring belt disposed along the second belt path. The latching mechanism is operable to lock the belt tightener in the first and second positions.
