Abstract: The child restraint of the present invention includes a waistband which is placed around the child. The waistband is retained in that position by hook and napped loop means such as VELCRO. The use of hook and napped loop means permits the waistband to be easily adjusted to fit the size of any particular child. The restraint further includes an elongated strap which is securely attached to the waistband. The strap is adapted to be looped around a suitable anchor, such as the parent's seatbelt or the armrest of the parent's seat. The end of the strap is passed around the fixed object and then threaded through a ring attached to the waistband. The strap is then pulled back across the ring so that it overlaps the portion of the strap projecting toward the ring. The overlapped portions of the strap are secured together by hook and napped loop means such as VELCRO. The device restrains the child from becoming dislodged from his parent's lap during landing and take-off or when turbulence is encountered.
