ABSTRACT:

FIELD
This invention relates to a child safety seat for use in a vehicle.
RELATED ART
It is well known for a child safety seat to rest on a vehicle seat and to be secured thereon by the corresponding vehicle seat belt. The disadvantage of this arrangement is that, even if the vehicle seat belt is pulled very tight during installation, the resilience of the belt will permit undesirable movement of the child seat relative to the vehicle in the event of sudden deceleration, for example during an accident. In order to overcome this disadvantage, it has been proposed to provide vehicle seats with standard anchorage units at agreed locations near the rear edge of the vehicle seat cushion and the bottom of the vehicle seat back for engagement by releasable connectors which are attached to the child seat, either rigidly or by relatively short straps. Such anchorage units will be referred to hereinafter as “standard anchorage units”.
When flexible straps are used to attach a child safety seat to standard anchorage units, the length of the strap must be sufficient to accommodate a strap adjuster to enable the strap to be tightened after the releasable connector has engaged with the corresponding standard anchorage units. On the other hand, in order to minimise angular movement of the child safety seat relative to the standard anchorage unit, transverse movement of the releasable connector relative to the child seat must be minimised.
SUMMARY OF THE INVENTION
According to the invention, a child safety seat comprises a seat body having first and second side surfaces, a first abutment surface extending between the side surfaces and adapted to abut against a seat cushion of a vehicle seat and a second abutment surface extending between the side surfaces and adapted to abut against a seat back of said vehicle seat, first and second strap guides each mounted on a respective side surface in proximity to both the first abutment surface and the second abutment surface, first and second strap anchorages each mounted on a respective side surface on the opposite side of the corresponding strap guide to the abutment surfaces, first and second straps each having a releasable connector on one end and each extending through a respective strap guide to the corresponding anchorage, and a strap adjustment mechanism located on the opposite side of the strap guide to the releasable connector for adjusting the length of strap between such releasable connector and the corresponding strap guide.
In one form of the invention, the adjustment mechanism comprises a respective strap adjuster for each strap located in the portion of such strap extending between the strap guide and the strap anchorage. Alternatively, each strap anchorage may be mounted on the seat body by adjustable mounting means permitting variation of its distance from the corresponding strap guide.
