Therefore, for example, when the user moves from the side end portion of the support base 11 to the outside in the left-right direction Y, the movement of the shoulder portion of the user can be restricted by the regulating portion 30 and the like. Thereby, the fall of the user can be suppressed more effectively. Further, since the fall can be effectively suppressed in this way, the amount of protrusion of the regulating portion 30 upward can be suppressed to be small. As a result, it is possible to prevent the regulation unit 30 from giving an excessive feeling of blockage to the user.

Further, in a state where the support base 11 is in the chair position P1, the regulation unit 30 is located on the rear side X2 of the backrest 22 of the support base 11. Therefore, for example, the movement of the user supported by the support base 11 of the chair position P1 is suppressed from being hindered by the regulation unit 30, and the usability of the body support device 10 can be ensured.

Further, in the state where the support base 11 is in the bed position P2, the protruding portion 31 is larger in the front-rear direction X than in the vertical direction Z. Therefore, it is possible to regulate the movement of the user in the left-right direction Y while suppressing the amount of protrusion of the regulating portion 30 upward. As a result, it is possible to suppress giving the user an excessive feeling of obstruction.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

The armrest 13 does not have to protrude upward from the support base 11.

Instead of the regulation unit 30, a configuration may be adopted in which the user supported by the support base 11 at the bed position P2 is provided with a recognition unit that recognizes the side end portion of the support base 11.
In this case, the recognition unit does not have to protrude upward from the support base 11 at the bed position P2. For example, in the cushion material of the support base 11, when the hardness of the side end portion in the left-right direction Y and the hardness of the central portion in the left-right direction Y are different and the user moves to the side end portion of the support base 11. In addition, the recognition unit may make the user recognize the side end portion of the support base 11 based on the change in the hardness of the cushion material.
Further, as the recognition unit, a configuration may be adopted in which the side end portion of the support base 11 is recognized without contacting the user. For example, the recognition unit includes a sensor that acquires the position of the user and a speaker that generates a warning sound based on the detection result of the sensor, and detects that the user is located at the side end of the support base 11. The speaker may generate a beep when detected by.

In addition, it is possible to replace the constituent elements in the above-described embodiment with well-known constituent elements as appropriate without departing from the spirit of the present invention, and the above-mentioned modified examples may be appropriately combined.
