Abstract

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.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to preventing an occupant's head from tipping forward while traveling in a child safety seat or wheelchair.
2. Description of the Background of the Invention
There is a rather large, and growing, population of disabled children that are unable to maintain head control. This usually results in their head tipping forward into an uncomfortable position when seated in an upright, or even a semi-reclined, position. This lack of head control is problematic for these children during vehicular transport in child safety seats and during general use of their wheelchairs, causing discomfort, and in some cases, breathing difficulty.

Child Safety Seat Version

Currently, children with disabilities weighing 40 lbs. or less can usually be safely transported in vehicles using reclined conventional child safety seats, which are widely available since they are designed for able bodied children. However, after outgrowing these products, disabled children still require child safety seats with a full harness in order to compensate for their lack of trunk control. Most of these children are transported in large medical (full harness) child safety seats, which are capable of restraining larger and heavier children. Unfortunately, none of the large medical child safety seats currently available on the market offer significant recline. The result is that many of these children have trouble keeping their heads upright, causing discomfort and in some cases obstructed breathing. This situation is even more problematic for children with tracheostomies (An air tube which penetrates the neck), who are much more likely to experience airway obstruction in the event that their heads are allowed to tip forward.
In an attempt to remedy this problem, some parents and pediatric therapists have resorted to such remedies as neck collars and towels to help in supporting the child's head. However, soft neck collars and towels are too soft to hold the head up properly and crash testing has revealed that “stiff” neck collars result in elevated loading on the occupant's neck, which can result in damage to the vertebrae or spinal chord. In any event, none of the large medical child safety seat manufacturers approve the use of towels or neck collars to support the head during vehicle transport.
The Traveller Plus by Snug Seat does offer a “recline bar” with its large medical child safety seat. However, it does not provide adequate recline according to interviews with dozens of therapists and monitoring of communications on the two largest list serves for medical professionals that work with these children.
Unfortunately, even if large medical child safety seats were designed with additional recline, the amount of leg room available to the occupant would be diminished by a corresponding amount. This is of particular concern for larger children in smaller vehicles and buses (which have closely spaced seats).

Wheelchair Version

The children described above have the same head control problems during general (both in and out of motor vehicles) use of their wheelchairs. This problem is often solved in wheelchairs by increasing recline. This solution is more practical in wheelchairs (compared to child safety seats) since leg room is generally not restricted as it is in a child safety seat. However, the present invention does allow wheelchair occupants to keep their heads upright without having to be reclined; which improves quality of life and allows the occupant improved interaction with people and the environment. Finally, during vehicular transport in a wheelchair, the present invention allows the child to sit upright without allowing the head to “flop” forward. This is very important since the vehicle's seat belt, which is used to restrain wheelchair occupants in motor vehicles, is designed for occupants in the upright position. Therefore, the present invention will improve safety by allowing the occupant to remain upright, which is the position that the seat belt was designed for.

SUMMARY OF THE INVENTION

Therefore, it is an object of this invention to overcome the previously mentioned problems and to specifically provide a method for restraining the occupant's head in a child safety seat with out diminishing leg room. For wheelchairs, it improves safety during vehicular transport and improves quality of life during general use of a wheelchair by allowing the occupant to sit upright without causing his head to flop forward.

Child Safety Seat Version

In its broadest form, the invention is a child safety seat, for use in a vehicle, with loop/hook attachment media connected to its backrest. The mating partner of this attachment media is sewn on the back of a cap to be worn by the occupant of the child safety seat. The attachment media on the head portion of the backrest of the child safety seat may alternately be attached to a headrest that is attached securely to the backrest of the child safety seat.
Therefore, this invention will provide a remedy for preventing the occupant's head from tipping forward.
In addition, crash testing has revealed that the invention is also capable of reducing HIC and Chest G values associated with the US Code Title 49, Part 571, FMVSS 213 performance requirements. Therefore the invention serves two purposes: keeping the child's head up and reducing risk of injury, by absorbing energy as the mating surfaces of the hook and loop (or similar media) media separate from each other.

Wheelchair Version

In its broadest form, the invention is a wheelchair, which may or may not be used in a vehicle, with loop/hook attachment media connected to its backrest. The mating partner of this attachment media is sewn on the back of a cap to be worn by the occupant of the wheelchair. The attachment media on the head portion of the backrest of the wheelchair may alternately be attached to a headrest that is attached securely to the backrest of the wheelchair.
Therefore, this invention will provide a remedy for preventing the occupant's head from tipping forward.
