[0002] Various techniques have been proposed for adjusting the shape of the sheet to fit different shapes of the supported object. Patent Document 1 proposes a seat cushion body that obtains optimal cushioning properties by changing the degree of soft elastic body application and the length of cylindrical cells in accordance with body pressure distribution.

[0003] In addition, the technology described in Patent Document 1 is composed of a fiber mat having a plurality of cylindrical cells inside the cushion body, and a soft elastic material that is applied to the fiber mat so as to permeate each cylindrical cell and then hardened. It is proposed that the amount of soft elastic material applied can be changed according to the body pressure distribution, thereby widening the range of change in cushioning properties.

[0004] Furthermore, Non-Patent Document 1 proposes a protector tool case in which blocks of urethane can be removed to fit the shape of the stored items, thereby protecting the stored items. [Prior art documents] [Patent documents]

[0019] 1 to 4 show an embodiment of a support surface-deforming sheet according to the present invention. In Fig. 1, the support surface-deforming sheet includes a cell assembly 2 in which a plurality of rod-shaped cells 1 are aligned so that adjacent cells are in contact with each other in the left-right and front-rear directions, and an elastic cushion 5 placed in contact with the underside 3 of the cell assembly 2.

[0020] In Figure 1, the support object 18 is pressed against at least a part of the support surface 14 formed by the upper surface 4 of the cell assembly portion 2, and the rod-shaped cells 1 in contact with the support object 18 are pressed in until the force applied to the support surface 14 and the elasticity of the cushion 5 are balanced, causing the support surface 14 to deform.

[0021] Figure 2 shows the state of the deformation process of the support surface. a shows the state before the support surface is deformed, b shows the state in which the support surface is deforming to fit the shape of the supported object, and c shows the state after the support surface is deformed.

[0022] In Figure 3, pressure is applied to the cell assembly 2 from at least one of the left-right and front-back directions, and the position of the rod-shaped cells 1 is maintained at any position in the up-down direction due to the frictional force between the rod-shaped cells 1, thereby maintaining the shape of the deformed support surface 14.

[0023] In FIG. 3, the position of the rod-shaped cells 1 constituting the deformed support surface 14 can be adjusted in the vertical direction by applying further external force.

[0024] Figure 4 shows the process of applying an external force to some rod-shaped cells on the support surface: a shows the state before adjusting the position of the rod-shaped cells, b shows the state during the adjustment of the position of the rod-shaped cells, and c shows the state after adjusting the position of the rod-shaped cells.

[0025] 5 and 6 show a first embodiment of the present invention. In Fig. 5, a pressure adjusting mechanism 7 is provided that adjusts the pressure applied to the cell assembly 2 from at least one of the left and right and front and rear directions.

[0026] In Figure 5, the pressure adjustment mechanism 7 has a wire 6 that passes through multiple rod-shaped cells 1 that make up the outer edge of the cell assembly 2, among the rod-shaped cells 1, and a wire adjustment unit 8 that can adjust the tension of the wire 6.The tension of the wire 6 can be adjusted with the wire adjustment unit 8 to adjust the pressure applied to the cell assembly 2.

[0027] In Figure 6, the pressure adjustment mechanism 7 is equipped with a wire adjustment support part 10 having a support plate 11 on the inside, and a compression coil spring 9 that is in contact with the upper surface of the support plate 11, and a wire adjustment part 8 is combined so as to cover the upper surface of the compression coil spring 9, and the wire adjustment part 8 slides up and down inside the wire adjustment support part 10.

[0028] In FIG. 6, the wire 6 is attached to the wire adjustment part 8 through a hole 13 drilled in the side of the wire adjustment support part 10 and a hole 12 drilled in the center of the support plate 11 . By sliding the wire adjustment part 8 up and down, the tension of the wire 6 is adjusted, and the pressure of the cell assembly part 2 is thereby adjusted.

[0029] In Figure 7, when the support object 18 is pressed against at least a part of the support surface 14 and the wire adjustment part 8 is pressed, the tension of the wire 6 decreases, the rod-shaped cells 1 in contact with the support object 18 are pressed to a position where the elasticity of the cushion 2 is balanced, and the support surface 14 is deformed.

[0030] In Figure 7, when the force pressing the wire adjustment part 8 is released, the tension of the wire 6 increases, pressure is applied to the cell assembly part 2, and the position of the rod-shaped cells 1 is maintained by the frictional force between the rod-shaped cells 1, thereby maintaining the shape of the deformed support surface 14.

[0031] In FIG. 7, by applying further external force to the rod-shaped cells 1 that constitute the deformed support surface 14, the position in the vertical direction can be adjusted.

[0032] 8 and 9 show a second embodiment of the present invention. In Fig. 8, a pressure adjusting mechanism 7 is provided that adjusts the pressure applied to the cell assembly 2 from at least one of the left and right and front and rear directions.

[0033] In Figure 8, the pressure adjustment mechanism 7 has a pressure plate 15 of the rod-shaped cells 1 that is approximately the same length as one side of the outer edge of the cell assembly 2 and is positioned opposite said side; an outer frame 16 to which both ends of the pressure plate 15 are attached and which, together with the pressure plate 15, surrounds the entire outer edge of the cell assembly 2; and a pressure adjustment lever 17 that can move the pressure plate 15 backward (contact) or forward (away) from one side.The pressure adjustment lever 17 moves the pressure plate 15 forward and backward, adjusting the force with which the pressure plate 15 presses against the one side, and thereby adjusting the pressure that the pressure plate 15 and outer frame 16 apply to the outer edge of the cell assembly 2.

[0034] In Figure 9, a cell assembly 2 is provided in which multiple rod-shaped cells 1 are aligned and arranged so that adjacent cells are in contact with each other in the left-right and front-back directions, and an elastic cushion 5 is arranged in contact with the underside 3 of the cell assembly 2.

[0035] In Figure 10, the support object 18 is pressed against at least a part of the support surface 14 formed by the upper surface 4 of the cell assembly portion 2, and the rod-shaped cells 1 in contact with the support object 18 are pressed in until the force applied to the support surface 14 is balanced with the elasticity of the cushion 5, causing the support surface 14 to deform.

[0036] In Figure 10, pressure is applied to the cell assembly 2 from at least one of the left-right and front-back directions, and the position of the rod-shaped cells 1 is maintained at any position in the up-down direction due to the frictional force between the rod-shaped cells 1, thereby maintaining the shape of the deformed support surface 14.

[0037] In Figure 10, after pressing a part of the support object 18 against the support surface 14, the pressure adjustment lever 17 is pulled up, causing the pressure plate 15 to move forward, and the rod-shaped cells 1 in contact with the support object are pressed down to a position where the elastic force of the cushion 5 is balanced, causing the support surface 14 to deform.

[0038] In FIG. 10, when the force pulling up the pressure adjustment lever 17 is released, the compression coil spring 9 expands, causing the pressure plate 15 to move backward, applying pressure to one side of the cell assembly 2 and maintaining the shape of the support surface 14.

[0039] In FIG. 10, by applying further external force to the rod-shaped cells 1 that constitute the deformed support surface 14, the position in the vertical direction can be adjusted.

[0040] In FIG. 11, the end side 19 of the rod-shaped cell 1 is at least one of a flat surface (a), a surface with chamfered corners (b), and a curved surface (c and d).

[0041] In FIG. 12, the end side 19 of the rod-shaped cell 1 is formed of a hard body, an elastic body, or a combination of an elastic body and a hard body. [Explanation of symbols]
