I have invented a means for keeping an occupant's head upright in a child safety seat or wheelchair. The invention comprises either a child safety seat or wheelchair with a backrest and a headrest with either loop or hook attachment media attached to the area of the headrest that contacts the back of the occupant's head (or, alternatively, in the head area of the backrest, with the headrest being omitted), with mating media attached to the backside of a cap to be worn on the head of the occupant. The occupant's head is held up by the mating of the attachment media between the cap and headrest or backrest. The purpose of this configuration is to prevent the occupant's head from tipping forward or to either side. When used in conjunction with a child safety seat, an additional purpose is to reduce injury values, such as HIC (Head Injury Criteria), neck injury, and Chest G values associated with the US Code Title 49, Part 571, FMVSS 213 performance requirements. In addition, the present invention is applicable to children and adults in other types of durable medical equipment such as standers and walkers.
