Waist straps and fittings for waist straps shall be secured to the frame of a high chair either directly or by their securement to the seat, which shall be secured to the frame of the high chair in such a way that the seat cannot be pulled away from the frame of the high chair by pulling the restraint straps.

(a) Shoulder straps shall meet the seat back with a maximum distance of 150 mm between their inside edges at the point at which they meet the seat back.
(b) Shoulder straps shall be attached to an adjustable strap that is incorporated with the front waist strap so as to encircle the child’s torso. The shoulder straps shall be joined and shall meet the part of the strap that is adjacent to the child’s back in such a way that the straps do not fall off the occupant’s shoulder.
