Summary of the Invention
The present invention provides an apparatus for supporting a wheelchair in a reclined position. When wheelchair occupants need dental care, their hair shampooed, or have other reasons of therapy or comfort requiring a reclined position, it is difficult to place the wheelchair in the proper position. Typically, the person moves from the wheelchair into a suitable chair or placement.
Wheelchairs designed to recline offer similar benefits to the present invention, however, if the occupant has a standard manual wheelchair, it is necessary for them to switch to the reclining chair, if available. If the person can move to a reclining wheelchair, it would be just as easy to move to a dentist's chair or shampoo chair. The present invention allows the occupant to remain in the wheelchair, without changing chairs, which can be difficult, dangerous, and often uncomfortable to the occupant. When in the reclined position, the wheelchair and support apparatus may be moved together to position the wheelchair.
The invention allows nursing homes to have inexpensive means of reclining wheelchairs, with no need for special staff training in the use of the equipment. It can be used for dental examinations, and other routine dental care. Hair care and shampooing, reclining, and exercising or physical therapy, are other uses where it is beneficial to have the occupant of the wheelchair in a reclining position.
Many elderly nursing home patients spend long hours in a wheelchair. This will allow them more flexibility to do things without getting out of the wheelchair, yet also allows a different position to redistribute the person's body weight. Wheelchairs tend to force the occupants forward, often leading to a slumped forward, kyphotic condition.
It is therefore an object of the present invention to provide a new, simple wheelchair tilting device that can be used inexpensively. It is a further object of the present invention to allow a person in a wheelchair to be securely positioned for dental examination, or shampooing, without removing the person from the wheelchair. It is still a further object of the invention to provide a wheelchair tilting device which is portable and reliable.

Detailed Description of the Preferred Embodiment
The invention is shown in FIG. 1 in a preferred embodiment. A main frame 4 of the invention consists of a tubular member. The frame 4 is fit over the outside diameter of the tubular member of the stand 7. Horizontal adjusting holes 5 are placed incrementally along the frame 4 and stand 7. This allows for adjustment of the height of the frame 4 by insertion of a cotter pin through the aligned holes of the frame 4 and stand 7. The stand 7 is welded, or fixed, to a base 8 to support the invention. It is beneficial to have caster wheels 9 on the bottom of the base 8 to allow the invention to roll. This also allows the combination of the wheelchair and support apparatus to roll together.
The top of the frame 4 is attached to a crossbar 1, 2. The recessed area of the crossbar 2 is relatively straight at its center, at the junction with the frame 4. The recessed area of the crossbar 2 is concave to the front of the invention. The chair engaging section of the crossbar 1 is a relatively straight section of tubular material to allow for various wheelchair widths. The crossbar may also be a straight tubular member. It is also possible to have straps to secure the wheelchair frame to the crossbar 1. Hook and loop fasteners, bungee-type cords, or similar means could be used to attach the wheelchair to the invention.
A wheelchair, with the occupant in it, is backed toward the front of the invention. The wheelchair is then tilted manually by a nurse, aide, or assistant, until the frame portion of the wheelchair at the bend for the handles of the wheelchair come to rest on the chair engaging section of the crossbar 1.
To allow for support of the head of the occupant, uprights 3 may be attached to the recessed area of the crossbar 2. A headrest 10 may be attached to the uprights 3 or attached with clips. Various headrests 10 may be utilized for different uses, such as a flat, padded piece for dentistry, a curved neck rest to allow for shampooing, or a pillow-like support for casual reclining. As shown in FIG. 3, a single headrest 10 may be reversible to provide head support,, or reversed to allow neck support for hair shampooing.
Hydraulics or springs may be used in the connection between the frame 4 and stand 7 to provide a cushioned movement of the sliding of the two tubular members. This may reduce the jolt of the wheelchair coming to rest on the invention.
For wheelchairs which do not have foot rests, or when desirable, it is also possible to provide a leg rest 11. This would support the occupant's legs in a reclined position, giving a more comfortable and secure position.
