2. Description of the Related Art Conventionally, wheelchair users such as critically ill patients and bedridden elderly people are sometimes transferred from a wheelchair to the bed side, but this transfer work causes a great deal of pain to the caregiver. That is, when transferring a patient to the bed side in the conventional wheelchair, after bringing the wheelchair close to the side of the bed, a plurality of caregivers cooperate to lift the patient's body and carry it to the center of the bed as it is. There was a need.

This is also the case when the patient is transferred from the bed to the wheelchair side, and it is necessary for a plurality of caregivers to lift the patient on the bed and carry it to the seat surface of the wheelchair as it is. Moreover, when the patient is lifted, the caregiver is forced to have an unnatural posture, which often causes the caregiver's legs and back to be hurt. Therefore, in order to reduce the work of the caregiver, a deployment type wheelchair has been devised in which the backrest part and the lower limb support part of the wheelchair can be deployed at the same height as the seat surface and can be adjusted to the same height as the bed. (JP-A-10-52459, JP-A-5-329185).

However, it has been difficult to eliminate the pain of the caregiver even with the use of the deployable wheelchair. That is, at the time of transfer work, the caregiver needs to lift the patient on the wheelchair and move it laterally to the center of the bed, which requires unnatural labor for the caregiver.
Both patients and caregivers were distressed. Also,
Many problems remain, such as how to move the patient between the wheelchair and the bed, or how to prevent the wheelchair from rolling when the patient is moved laterally. In addition to this, auxiliary devices such as a lifting device using a belt, a method using a roller belt for lateral movement of a patient, and a method using a sliding plate have been proposed. These devices also have merits and demerits, and they do not exert sufficient functions for transfer between a wheelchair and a bed.

When the patient slides down on the bed and is placed on the horizontal support from the bed, a known sliding plate or a rotating roller type sliding assist device is attached to the rotary seat surface, the backrest and the lower limb support. By using it together, it is possible to easily get on and off the bed. When the patient is supine on a horizontal support, there is a risk that the center of gravity of the patient moves to the head side and the trolley rolls over. In order to prevent this, the position of the center of gravity of the patient in the supine state needs to be aligned with substantially the center of the left and right of the carriage. In order to make the centers of gravity coincide with each other, an inclined hinge of the backrest may be provided near the center of rotation of the rotary seat surface. Or when deploying the backrest horizontally,
It is possible to provide a mechanism capable of slidingly moving the horizontal support table so that the center of gravity position where the horizontal support table and the patient are combined approaches the rotation center by the interlocking slide mechanism.
