Abstract
Abstract A child safety seat for use in a vehicle comprises a seat body having a seat portion and a backrest portion. Guides on the seat body define a strap path for a strap of an adult seat belt which secures the seat body to a vehicle seat. A strap deflecting lever is movable between a first position clear of said strap path and a second position in which the strap is deflected and thus tightened.
