When the bed user gets up, as shown in FIG. 8, first, the interlocking button is pressed to instruct the start of the getting up operation (step S11).

When the interlocking button is pressed, a knee-raising mechanism (not shown) operates to perform a knee-raising operation to a predetermined position (step S12). Then, the back undulating mechanism 310 operates to raise the back to a predetermined position (step S13).

Then, with the bed user raised to a predetermined position, the back side undulating mechanism 320 undulates the end side of the back bottom 3a in the bed width direction and tilts the back in a specified direction (step). S14). Then, the knee-lowering motion is performed by the knee-raising mechanism to flatten the bed floor (step S15).

In this way, the bed user is inclined and raised in the desired direction, the bed user is in a state where he / she can easily get up, and the back-raising operation is completed.

In the raising motion of the bed user in the second embodiment, the timing and the amount of the knee raising motion by the knee raising mechanism and the back raising motion by the back undulating mechanism 310 are appropriately set to be comfortable for the bed user. It may be possible to set and adjust.

The bed user is provided with the undulation mechanism 320, and the back undulation mechanism 310 and the back side undulation mechanism 320 are configured so that the drive control can be independently performed, for example, when the bed user is raised. The bed user can easily get up because the side end of the first back bottom 3a1 or the second back bottom 3a2 can be raised and tilted by the back lateral undulation mechanism 320 so that the upper body can be easily oriented in the desired direction. be able to. In this way, it is possible to realize a bed device that facilitates the adjustment of the posture of the bed user and allows the bed user to change the posture in a comfortable state.

Further, in the first embodiment, as a configuration of the undulation mechanism, a back undulation mechanism 310 is provided as the first back undulation mechanism and a back side undulation mechanism 320 is provided as the second back undulation mechanism, and the back bottom 3a is operated. As a configuration, by providing drive arms 311, 321 and urging the back bottom 3a only in the direction of pushing up (raising), the back raising operation can be smoothly performed and the back bottom 3a can be performed in the back lowering operation. Since is link-free, it is possible to manually raise the back without relying on the first actuator 312 and the second actuator 322. As a result, workability and maintainability can be improved, and the risk of property damage due to pinching by the actuator drive when the back is lowered can be reduced.

In the first embodiment, the back undulating mechanism 310 and the back side undulating mechanism 320 are configured to enable independent drive control, but the back undulating mechanism 310 and the back side undulating mechanism 320 are interlocked with each other.

Next, a case where the bed user gets up by the bed device of the fifth embodiment will be described.

When the bed user gets off from the left side of the bed while lying on his back, the back raising operation is executed and the first support portion 5031 is raised by the back undulating mechanism 5310, so that the back support portion 503a and the back side are sideways. By raising the undulating mechanism 5320 integrally, the upper body of the bed user is raised.

Then, the back side undulating mechanism 5320 is rotated so that the right side of the back support portion 503a rises so that the upper body of the bed user faces the left side.

By doing so, the bed user can easily raise the right side of the upper body and move the body toward the left side.

At this time, the operation of the back undulating mechanism 5310 and the back lateral undulating mechanism 5320 is such that the back lateral undulating mechanism 5320 is operated after the back undulating mechanism 5310 is operated, but the operation of the back undulating mechanism 5310 is the same as the operation of the back undulating mechanism 5310.
