For example, the bedclothes 1 includes two respiratory heartbeat measuring units 2. The respiratory heartbeat measuring unit 2 is a respiratory heartbeat measuring sensor. As an example, the respiratory/heartbeat measuring unit 2 is a piezoelectric sensor including a coaxial line. However, the type of the respiratory heartbeat measuring unit 2 can be changed as appropriate. Further, in the present embodiment, the respiration measurement unit 2 that measures respiration and the heartbeat measurement unit that measures the heartbeat are integrated into the respiration heartbeat measurement unit 2. However, the respiration measurement unit and the heartbeat measurement unit may be separately provided independently of each other.

For example, the respiratory heartbeat measuring unit 2 includes a respiratory heartbeat measuring unit 2A disposed at a position having a length L1 from one end 1a in the longitudinal direction D1 of the bedclothes 1, and a respiratory heartbeat disposed at a position having a length L2 from one end 1a. The measuring unit 2B is included. The respiratory heartbeat measuring unit 2A and the respiratory heartbeat measuring unit 2B both extend in the width direction D2 of the bedclothes 1. The length L1 is a length corresponding to the position from the shoulder M1 of the user M to the chest M2, and the length L2 is a length corresponding to the position of the waist M3 of the user M.

FIG. 3 is a cross-sectional view when the bedclothes 1 is cut along the vertical direction. The bedding 1 is, for example, a mattress. As an example, the bedclothes 1 includes a cushion material 5 and a side material 9 that covers the cushion material 5, and the side material 9 covers the cushion material 5. The respiratory heartbeat measuring unit 2, the body movement measuring unit 3, and the blood pressure measuring unit 4 are provided on the upper portion 5A of the bedclothes 1. In the present specification, the “upper part” refers to a portion above a lower surface of an object, and may refer to a portion including an upper half portion of an object and a portion including an upper surface of an object.

The cushion material 5 is, for example, a base portion 6 having a rectangular parallelepiped shape, a plurality of first projections 7 (projections) provided on the upper surface 6a of the base portion 6, and a first surface provided on the top surface 7b of each first projection 7. Two protrusions 8 (projections) are provided. As an example, the base portion 6 and the first protrusions 7 are harder than the second protrusions 8, and each second protrusion 8 has a sponge shape. The first protrusions 7 and the second protrusions 8 may be arranged in a grid pattern on the upper surface 6 a of the base portion 6.

The base portion 6 includes, for example, a slit 6b (recess) that extends downward from the upper surface 6a. As an example, the slit 6b has a linear portion 6c extending downward from the upper surface 6a, and an expansion portion 6d that expands at the lower end of the linear portion 6c. The expanded portion 6d extends, for example, in a circular shape from the lower end of the linear portion 6c, but the shape of the expanded portion 6d can be changed as appropriate. In this way, the cushioning property of the cushion material 5 is enhanced by forming the expanded portion 6d at the lower end of the linear portion 6c of the slit 6b.

The base portion 6 includes a plurality of slits 6b, and, for example, the plurality of slits 6b may be periodically provided in the cushion material 5. As described above, by providing the plurality of slits 6b, it is possible to widen the region having a high cushioning property, and by periodically providing the plurality of slits 6b, it is possible to uniformly arrange the region having a high cushioning property. Become.

The material of the first protrusion 7 is the same as the material of the base portion 6, for example. For example, a plurality of first protrusions 7 are provided between the two slits 6b. That is, the plurality of first protrusions 7 are provided on the island portion 6e of the base portion 6 formed between the two slits 6b. As an example, three rows of the first protrusions 7 are arranged on the island portion 6e. The material of the first protrusion 7 may be different from the material of the base portion 6, and can be changed as appropriate.

The first protrusion 7 has, for example, a truncated quadrangular pyramid shape. Specifically, the first protrusion 7 includes a plurality of oblique sides 7a extending upward from the upper surface 6a of the base portion 6 and a top surface 7b extending along the upper surface 6a between the upper ends of the plurality of oblique sides 7a. The hypotenuse 7a is curved so as to bulge outside the first protrusion 7, for example. Further, in a side view, the first protrusion 7 may have a trapezoidal shape with two oblique sides 7a serving as legs. The top surface 7b is, for example, a flat surface. However, the shapes of the oblique side 7a and the top surface 7b can be appropriately changed, and the shape of the first protrusion 7 is not limited to the truncated quadrangular pyramid shape, and can be appropriately changed.

The second protrusion 8 is a protrusion placed on the top surface 7 b of the first protrusion 7 and forms the upper end surface of the cushion material 5. The second protrusion 8 has, for example, a parabolic shape whose apex is located at the upper end. However, the shape of the second protrusion 8 may be, for example, an arc shape, and can be changed as appropriate. As an example, the second protrusion 8 is colored, and for example, the color of the second protrusion 8 is different from the colors of the base portion 6 and the first protrusion 7. As a result, the colored second protrusions 8 are arranged in a grid pattern, so that the design of the cushion material 5 is enhanced.

In the sensor unit 2a, when an external force is applied, a voltage is generated from the piezoelectric material, and the voltage associated with the external force is output from the sensor unit 2a to detect the respiration and the heartbeat of the user M. It should be noted that this type of respiratory heartbeat measuring unit 2 can also detect the body movement of the user M. The protective portion 2b is, for example, a colored transparent film formed by pasting, and may be formed by laminating.

The respiratory heartbeat measuring unit 2 includes, for example, a tension relaxing unit 2c at a position facing the slit 6b of the cushion material 5. The tension relieving portion 2c may be, for example, a slack portion that loosens at a position facing the slit 6b, and is arranged with a margin at a position facing the slit 6b. The tension relieving portion 2c can suppress disconnection of the respiratory heartbeat measuring unit 2 even if a force acts in a direction in which the pair of slits 6b are separated from each other and spread.

The respiratory heartbeat measuring unit 2 may be fixed to the top portion 8a of the second protrusion 8, for example. The respiratory heartbeat measuring unit 2 may be fixed to only a part of the plurality of tops 8a, or may be fixed to all of the plurality of tops 8a. Further, the respiratory heartbeat measuring unit 2 may be provided, for example, between the back surface 9a of the side ground 9 and the top portion 8a of the second protrusion 8 or may be fixed to the back surface 9a of the side ground 9. As a means for fixing the respiratory/heartbeat measuring unit 2, various methods such as sewing, adhering or welding may be used.
