A child's vehicle safety chair includes a chassis (1), a seat shell (4) and an adjustment device. The chassis (1) is securable in a vehicle seat. The seat shell (4) has a seating surface (5), a back support surface (6) and preferably also side support surfaces (7) for a child occupying the seat shell. With the adjustment device, the seat shell is adjustably secured in the chassis. The adjustment device includes an openable friction coupling which, in the open state, permits relative movement between the seat shell (4) and the chassis (1) and which, in the locked state, realises a predetermined locking action between the seat shell and the chassis. The locking action is adapted to permit relative movement between the seat shell and the chassis. The locking action is adapted to permit relative movement between the seat shell and the chassis under the action of the G-forces acting on the child occupant and the seat shell during a collision.
