Abstract

The transfer assistance device includes a bogie, an arm tiltably supported by the bogie, a holding part that is supported by the arm and holds a torso of a person being assisted. The holding part includes at least a low pressure cell group and a high pressure cell group configured to respectively face different parts of a front surface of the torso of the person being assisted. The transfer assistance device further includes air pressure adjuster configured to individually adjust air pressure of the low pressure cell group and air pressure of the high pressure cell group.

First claim

What is claimed is:

1 . A transfer assistance device comprising:
a bogie; an arm tiltably supported by the bogie; and a holding part that is supported by the arm and includes at least one of a front surface holding part, a lateral surface holding part, and a back surface holding part, the front surface holding part configured to hold a front surface of a torso of a person being assisted, the lateral surface holding part configured to hold a lateral surface of the torso of the person being assisted, and the back surface holding part configured to hold a back surface of the torso of the person being assisted, wherein the holding part comprises at least a first bag and a second bag configured to respectively face different parts of at least one of the front surface, the lateral surface, and the back surface of the torso of the person being assisted, and the transfer assistance device further comprises an air pressure adjuster configured to individually adjust air pressure of the first bag and air pressure of the second bag.

2 . The transfer assistance device according to claim 1 , wherein
the first bag is configured to face a solar plexus of the front surface of the torso of the person being assisted, the second bag is configured to face some or all parts other than the solar plexus of the front surface of the torso of the person being assisted, and the air pressure adjuster is configured to adjust the air pressure of the first bag to be lower than the air pressure of the second bag when the holding part holds the person being assisted.

3 . The transfer assistance device according to claim 1 , wherein the first bag includes a first cell group and the second bag includes a second cell group, and the cells of the first cell group have a relatively lower pressure than the cells of the second cell group.

4 . The transfer assistance device according to claim 3 , wherein the air pressure adjuster includes:
positive pressure supply means for supplying positive pressure to the first cell group and the second cell group, and negative pressure supply means for supplying negative pressure to the first cell group and the second cell group.

5 . The transfer assistance device according to claim 4 , wherein the positive pressure supply means includes a compressor and a positive pressure tank.

6 . The transfer assistance device according to claim 4 , wherein the negative pressure supply means includes a vacuum pump and a negative pressure tank.

7 . The transfer assistance device according to claim 3 , wherein the cells of the first cell group and the cells of the second cell group are not connected.

8 . The transfer assistance device according to claim 3 , wherein the air pressure adjuster is configured to individually adjust air pressure that is common to the first cell group and air pressure that is common to the second cell group.
