Abstract
Abstract A child safety seat for use in a vehicle, comprises 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. The side wings are moveable 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.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
112 words
A child safety seat for use in a vehicle, the child seat comprising: a seat body having a seat portion and a backrest, side wings movably mounted on the seat body so as to project from each side of the backrest at a level of a head of a child occupant of the seat, an inertia sensor, and drive means for moving the movable side wings relative to the backrest from a normal position to a fully deployed position, in which the movable side wings project from the backrest to a greater extent than when in the normal position of the movable side wings, in response to actuation of the inertia sensor.
Claim 2
Dependent Claim
112 words
A child safety seat for use in a vehicle, the child seat comprising: a seat body having a seat portion and a backrest, side wings movably mounted on the seat body so as to project from each side of the backrest at a level of a head of a child occupant of the seat, an inertia sensor, and drive means for moving the movable side wings relative to the backrest from a normal position to a fully deployed position, in which the movable side wings project from the backrest to a greater extent than when in the normal position of the movable side wings, in response to actuation of the inertia sensor.
Claim 3
Dependent Claim
28 words
