Conventional body support mechanisms that alternately decompress and support the bodies of patients, etc. in groups include a large number of inflatable and deflated air sacs arranged vertically and horizontally, and these air sacs separated into groups. There is an air mat that can be inflated and deflated by communicating with it. Such an air mat supplies pressurized air using an air pump to pressurize the air sacs in one group, and at the same time depressurizes the air sacs in the other group by removing air. By repeating this alternately, the pressurized body part is depressurized after a predetermined period of time has elapsed, thereby preventing obstruction of blood circulation due to continued pressurization for a long time.

時の異和感等の問題点もある。 However, since air mats perform pressurization and depressurization by taking in and out air in this way, it is difficult to shorten the pressurization and depressurization cycle beyond a certain degree, and the blood flow during the pressurization period is reduced. The problem is that the inhibition continues for a relatively long time. Also,
Air mats are made of airtight resin sheets, so they tend to accumulate heat and moisture between the parts of the body that come into contact with them. There are problems with the use of air support, and furthermore, there are problems such as seasickness and discomfort when sleeping.

発生を予防することができる。 Therefore, when only the tension coil springs 2 corresponding to the coil springs 1 of group A are energized, the temperature rises due to Joule heat, and the tension coil springs 2 contract due to the shape memory effect, causing the coil springs to spring up. 1 is contracted, and the tension coil spring 2 corresponding to the coil spring 1 of group B which is not energized remains as it is, so the body load on the cushion mechanism of the present invention is:
Most of the coil springs are supported by a portion of group B coil springs. Next, when the energization to the tension coil springs 2 corresponding to the coil springs 1 of group A is stopped, and the energization to the tension coil springs 2 corresponding to the coil springs 1 of group B is started,
The coil spring 1 of group B expands again as the tension coil spring 2 decreases in temperature due to heat radiation, and the coil spring 1 of group B expands.
Since the tension coil spring 2 contracts as it contracts due to the rise in temperature, the load of the body is now supported by the first part of the coil spring of group A. By continuously performing energization control for each of groups A and B, the parts of the body that are supported by the coil springs 1, that is, the parts of the body that are pressurized, are connected to the groups A and B. By alternately reducing the pressure in accordance with the distribution of pressure, and thus preventing obstruction of blood circulation due to continued pressurization for a long time, it is possible to prevent the occurrence of bedsores.

By providing appropriate elasticity, the effect of reducing the pressure at the pressurized area described above can be improved.
The body-supporting cushion mechanism of the present invention can be configured as a mattress using a structure similar to that of a spring unit in a conventional spring mattress. Furthermore, as described above, the body support cushion mechanism of the present invention can be used as a body support device fixed on the floorboard of a bed or as a mattress, or can be used alone for whole body use, or in combination with other body support mechanisms. It is also appropriate to configure it for whole body use. For example, the body support mechanism in the embodiment shown in FIG.
4 is made bulky by being vibrated by a vibrating device 15 and made to flow, and the air-permeable coating 16 on the upper surface is made bulky.
By distributing and supporting the body pressure of the above-mentioned area by the bulk density, the occurrence of bedsores is prevented.

As described above, the present invention has a large number of coil springs arranged in a matrix, a tension coil spring made of a shape memory alloy is connected between both ends of each coil spring, and a current-carrying electric wire is connected to the tension coil spring. are connected to each other to produce a shape memory effect when energized, and by controlling the energization of each group of tension coil springs, each group is alternately contracted, and the coil springs are alternately contracted and the coil springs are Since the body part under pressure is depressurized after a predetermined period of time has elapsed, there is an effect that bedsores can be prevented by preventing obstruction of blood circulation due to continued pressurization for a long period of time. And, compared to the conventional air mat, which is composed of airtight resin sheets and alternately supports the body using air pressure, the present invention has the following advantages:
Not only can breathability be improved, but the occurrence of seasickness and discomfort during sleeping is extremely low, and the cycle of pressurization and depressurization in depressurizing the pressurized area can be shortened. In addition to better preventing bedsores, it is also easy to change the connection of the current-carrying wires from each tension coil spring, or to change the connection electrically as appropriate in advance, In this way, it is easy to change the distribution of groups to be controlled alternately, or to make these changes programmatically, and the cycle of pressurization and depressurization can also be easily adjusted as necessary. . Furthermore, the present invention is configured such that the contraction of the coil spring is performed by a tension coil spring made of a shape memory alloy connected to both ends of the coil spring, so that the coil spring itself can be made of ordinary inexpensive spring steel. Compared to the case where the tension coil spring itself is made of a shape memory alloy, it can be constructed at a lower cost, and it has the advantage that electrical insulation between the tension coil springs corresponding to adjacent coil springs can be easily achieved.
