Patent ID: 8235464

Claim:
Seat to accommodate a child in a vehicle, the seat being adapted for secure connection to the vehicle; the seat having a support portion on which a child may sit, a backrest portion configured to restrict movements of the back of the child, and a headrest configured to restrict movements of the back of the head of the child, in which a first upright member is connected to a rear part of, or a rear extension to, the support portion and a second upright member is connected to a rear part of, or a rear extension to, the headrest, the upright members being parallel to each other, and in which there is adjustment means to adjust the relative position of the headrest with respect to the support portion, the adjustment means comprising a rotary member rotatable about a horizontal axis fixed with respect to the rear portion, the rotary member having grips at its ends projecting sideways from the support portion within or behind the support portion and projecting detents between the grips, the detents being arranged to engage facing slots of identical pitch apart in the first and second upright members, the upright members being resiliently biased towards each other, the arrangement being such that when the rotary member is turned by the grips, the detents, through the rotation of the rotary member and being in engagement with facing slots, will first force the upright members apart, and then lift the first upright member relative the second upright member, whereafter the detents will allow the first and second upright members to come together again, the rotation causing the rear portion to raise the distance between two adjacent slots and the headrest by twice the distance between two adjacent slots.
