ABSTRACT:

FIELD
This invention relates to a child safety seat for use in a vehicle, of the type comprising a seat body having a seat portion, a backrest and side wings projecting from each side of the backrest at the level of the head of a child occupant of the seat.
SUMMARY OF THE INVENTION
According to the invention, in a child safety seat of the type described above, the side wings are mounted for movement relative to the backrest so as to be displaceable between a normal position and a fully deployed position in which they project from the backrest to a greater extent than when in their normal position.
When in their deployed position, such wings provide enhanced protection for a child occupant of the seat in the event that the vehicle to which it is fitted is subject to having a component acceleration in the transverse direction, for example if the vehicle is subject to side impact.
In a preferred form of the invention, the child safety seat includes drive means for moving the side wings from their normal position to their deployed position in response to actuation of an inertia sensor. Both wings may be arranged for simultaneous deployment. Alternatively, the arrangement may be so as to deploy only the wing on the side towards which the child safety seat is being accelerated, such wing thus being interposed between the child occupant and external objects penetrating into the passenger compartment of the vehicle as a result of side impact. The side wings may also be arranged for manual deployment so as to allow the seat to be used with both wings already deployed, if desired.
