Abstract
Abstract A child safety seat for use in a vehicle comprises a seat body (10) having a seat portion (14) and a backrest portion (16). Guides (52) on the seat body (10) define a strap path for a strap (50) of a vehicle seat belt which secures the seat body (10) to a vehicle seat. A strap deflecting lever (62) is movable between a first position clear of said strap path and a second position in which the strap (50) is deflected and thus tightened. <IMAGE>

A child safety seat according to any preceding claim, further comprising blocking means (66, 68; 354, 356) arranged to obstruct passage along said strap path of objects of larger cross-section than said strap (50, 248, 348) when the strap deflecting means is in its second position.
Claim 6
Dependent Claim
44 words
A child safety seat according to any preceding claim, wherein the strap deflecting means comprises a pivotally mounted lever (60, 62) and manually operable control means (82, 92, 122) for causing angular movement of said lever (60, 62) between said first and second positions.
