Problems to be Solved by the Invention

[0005] An object of the present invention is to provide a posture support device that can suppress the exposure of the support member to the seated person side when the support member is disposed on a fixing plate on which the support member is disposed on the seat.

Means for Solving the Problems

[0006] The present invention, which achieves the above objective, is as follows. (1) A posture support device that supports the posture of a person sitting in a seat, At least one fixed plate formed separately from the sheet and disposed on the sheet, At least one support member is provided on the aforementioned fixed plate, It has, A posture support device having at least one skin on the side of the fixed plate that is closer to the seated person. (2) The seat has a seat cushion and a seat back, The aforementioned fixing plate has a back-side fixing plate which is disposed on the seat back side of the seat cushion and the seat back, The aforementioned surface material includes the seat cushion and the back surface material which is disposed on the seat back side of the seat back, The posture support device according to (1), wherein the back surface is fixed to the upper part of the back fixing plate at the upper part of the back surface. (3) The posture support device according to (2), wherein the back surface is detachably attached to the lower part of the back fixing plate at the lower part of the back surface. (4) The seat has a seat cushion and a seat back, The aforementioned fixing plate has a cushion-side fixing plate which is disposed on the seat cushion side of the seat cushion and the seat back, The aforementioned surface has a cushion-side surface which is disposed on the seat cushion side of the seat cushion and the seat back, The posture support device according to (1), wherein the cushion-side surface is fixed at the rear of the cushion-side fixing plate. (5) The posture support device according to (4), wherein the cushion-side surface is detachably attached to the front of the cushion-side fixing plate at the front of the cushion-side surface. [Effects of the Invention]

[0007] According to the posture support device described in (1) above, since there is at least one skin on the side of the fixed plate that is closer to the seated person, the skin can cover and conceal the support member that is placed on the fixed plate, thereby preventing the support member from being exposed to the seated person. Therefore, (a) even if support members are installed on the fixed base, the seat portion can be made closer to a flat surface with the upholstery. This reduces the perception that something is attached to the seat, and the appearance is perceived as improved. Also, (b) even when multiple support members are installed side by side on the fixed base and grooves or steps occur between the side by side support members, the upholstery is interposed between the seated person and the grooves or steps, and the upholstery tends to be a continuous surface, thus reducing the feeling of discomfort that people experience when using the seat.

[0008] According to the posture support device described in (2) above, the back side skin is fixed to the upper part of the back side fixing plate at the upper part of the back side skin, so unlike (a) when the back side skin is not fixed to the back side fixing plate, the loss of the skin can be suppressed. Also, (b) when the support member provided on the back side fixing plate is exposed by peeling back the back side skin and its position is adjusted relative to the back side fixing plate, the support member can be covered again with the back side skin simply by lowering the peeled-up skin after the position of the support member has been adjusted by peeling up the back side skin, so even when a back side skin is provided, the position of the support member can be adjusted relatively easily.

[0009] According to the posture support device described in (3) above, since the back surface is detachably attached to the lower part of the back fixing plate at the lower part of the back surface, it is possible to suppress displacement of the back surface relative to the back fixing plate due to the movement of the sitter's posture when sitting down, standing up, or while seated, compared to a case where the back surface is only fixed to the upper part of the back fixing plate at the top and not detachably attached to the lower part of the back fixing plate at the bottom.

[0010] Furthermore, since the back cover is fixed to the upper part of the back fixing plate at the top and detachable from the lower part of the back fixing plate at the bottom, (i) unlike the case where the back cover is fixed to the back fixing plate at both the top and bottom, the support member can be exposed by peeling back the back cover and the position of the support member can be adjusted relatively easily relative to the back fixing plate. Also, (ii) compared to the case where the back cover is detachable from the back fixing plate at both the top and bottom, the distance required for fastener installation to make it detachable can be shortened and the number of buttons can be reduced, reducing the effort required to attach and detach the back cover to the back fixing plate when adjusting the position of the support member, and thus reducing the workload when adjusting the position of the support member.

[0011] According to the posture support device described in (4) above, the cushion-side skin is fixed to the rear of the cushion-side fixing plate at the rear of the cushion-side skin. Therefore, unlike the case where (a) the cushion-side skin is not fixed to the cushion-side fixing plate, the loss of the skin can be suppressed. In addition, (b) when the support member provided on the cushion-side fixing plate is exposed by peeling back the cushion-side skin and adjusted in position relative to the cushion-side fixing plate, the support member can be covered again with the cushion-side skin simply by lowering the peeled-up skin after the support member has been positioned by peeling back the cushion-side skin. Therefore, even when a cushion-side skin is provided, the position of the support member can be adjusted relatively easily.

[0012] According to the posture support device described in (5) above, since the cushion-side surface is detachably attached to the front of the cushion-side fixing plate at the front of the cushion-side surface, compared to a case where the cushion-side surface is only fixed to the rear of the cushion-side fixing plate at the rear and not detachably attached to the front of the cushion-side fixing plate at the front, it is possible to suppress displacement of the cushion-side surface relative to the cushion-side fixing plate due to the movement of the sitter's posture when sitting down, standing up, or while seated.

[0013] In addition, since the cushion-side outer skin is fixed to the rear part of the cushion-side fixing plate at the rear part and is detachable from the front part of the cushion-side fixing plate at the front part, (i) unlike the case where the cushion-side outer skin is fixed to the cushion-side fixing plate at both the rear part and the front part, by rolling up the cushion-side outer skin, the support member can be exposed and the position of the support member can be adjusted relatively easily with respect to the cushion-side fixing plate. Also, (ii) compared to the case where the cushion-side outer skin is detachable from the cushion-side fixing plate at both the rear part and the front part, the installation distance of the fasteners required for detaching can be shortened, the number of buttons installed can be reduced, etc., and the labor for detaching the cushion-side outer skin from the cushion-side fixing plate when adjusting the position of the support member can be reduced, and the work load during the position adjustment of the support member can be reduced.

Modes for Carrying Out the Invention

[0015] Hereinafter, the posture support device 10 of the embodiment of the present invention will be described with reference to the drawings. In the figure, UP indicates the upward direction of the seat, and FR indicates the forward direction of the seat.

[0016] The posture support device 10 according to an embodiment of the present invention (hereinafter, also simply referred to as the device) is a device that supports the posture of a seated person on the seat 100. The seat 100 is, for example, a driver's seat mounted on a vehicle. However, the seat 100 may be a vehicle seat such as a passenger seat, a rear seat, or an auxiliary seat. Further, the seat 100 may not be a vehicle seat but a chair used in a home or the like.

[0017] As shown in FIG. 1, the seat 100 includes a seat cushion 110 that supports the lower body of the seated person from below, a seat back 120 that is disposed at the rear end of the seat cushion 110 and supports the upper body of the seated person from behind, and a headrest 130 that is provided above the seat back 120 and supports the head of the seated person from behind. However, the headrest 130 may not be provided.

[0018] The seat cushion 110 has side supports 110b at both left and right ends, the upper ends of which bulge upward from the left and right central portion 110a of the seat cushion 110. Further, the seat back 120 has side supports 120b at both left and right ends, the front ends of which bulge forward from the left and right central portion 120a of the seat back 120. However, in the embodiment of the present invention and the illustrated example, the case where both the side support 110b of the seat cushion 110 and the side support 120b of the seat back 120 are provided will be described, but either one or both of the side supports 110b and 120b may not be provided.

[0019] The seat cushion 110 has a general surface 111 and a front end surface 112. The general surface 111 is the surface on which the seated person sits and may also be referred to as the upper surface. The front end surface 112 is the surface at the front end of the seat cushion 110 and is a surface that slopes downward as it goes forward from the front end of the general surface 111.

[0020] The seat back 120 has a front surface 121. The front surface 121 is the surface that supports the seated person from behind.

[0021] The device 10 includes at least one fixing plate 20 formed separately from the seat 100 and disposed on the seat 100, at least one support member 30 disposed on the fixing plate 20, and at least one upholstery 40 positioned on the seated side of the fixing plate 20.

[0022] The fixing plate 20 can also be called the base. The fixing plate 20 is made of a flexible material, for example, it is made of fiber to provide versatility. However, the fixing plate 20 may be made of metal or resin as long as it is flexible. If the fixing plate 20 is made of fiber, it may be a cloth made by knitting or weaving fibers, a nonwoven fabric, or a cloth similar to a nonwoven fabric. If the fixing plate 20 is made of resin, it may be made of a soft resin such as rubber.

[0023] The fixing plate 20 includes a back-side fixing plate 21 which is disposed on the seat back 120 side of the seat cushion 110 and the seat back 120, and a cushion-side fixing plate 22 which is disposed on the seat cushion 110 side of the seat cushion 110 and the seat back 120.

[0024] The back-side fixing plate 21 is located in the area that supports the upper body of the seated person and is arranged along the seat back 120. The back-side fixing plate 21 is positioned so as to overlap with at least a portion of the left and right central portion 120a of the seat back 120 when viewed from the front. The back-side fixing plate 21 may also be positioned so as to overlap with the side support 120b of the seat back 120 when viewed from the front, or it may not be positioned so as to overlap with the side support 120b.

[0025] The rear-side fixing plate 21 is positioned and held on the seat back 120. The rear-side fixing plate 21 may be fixed to the seat back 120 or it may be detachable. The rear-side fixing plate 21 may also be adjustable in position relative to the seat back 120.

[0026] The cushion-side fixing plate 22 is located in the area that supports the lower half of the seated person's body and is arranged along the seat cushion 110. In a top view (plan view), the cushion-side fixing plate 22 is positioned to overlap with at least a portion of the left and right central portion 110a of the seat cushion 110. In a top view (plan view), the cushion-side fixing plate 22 may also be positioned to overlap with at least a portion of the side support 110b of the seat cushion 110, or it may not be positioned to overlap with the side support 110b.

[0027] The cushion-side fixing plate 22 is positioned and held on the seat cushion 110. The cushion-side fixing plate 22 may be fixed to the seat cushion 110 or it may be detachable. Furthermore, the cushion-side fixing plate 22 may be adjustable in position relative to the seat cushion 110.

[0028] The back-side fixing plate 21 and the cushion-side fixing plate 22 may be formed as a single unit or as separate units. If the back-side fixing plate 21 and the cushion-side fixing plate 22 are formed as separate units, they may be used simultaneously, only the back-side fixing plate 21 may be used and the cushion-side fixing plate 22 may not be used, or only the cushion-side fixing plate 22 may be used and the back-side fixing plate 21 may not be used. In the illustrated example, the case in which the back-side fixing plate 21 and the cushion-side fixing plate 22 are formed as a single unit is shown.

[0029] The support member 30 is detachable from the fixed plate 20. That is, the support member 30 is detachably mounted on the fixed plate 20. The position of the support member 30 relative to the fixed plate 20 can be changed to any position and angle. The mounting structure of the support member 30 to the fixed plate 20 is not particularly limited as long as the support member 30 is detachable from the fixed plate 20 and the position of the support member 30 relative to the fixed plate 20 can be changed. The mounting structure of the support member 30 to the fixed plate 20 is not particularly limited, but it is a mounting structure such as hook and loop fasteners or male and female interlocking fasteners that makes it difficult for the support member 30 to shift position relative to the fixed plate 20.

[0030] The support member 30 may be made of urethane, metal, or resin. If the support member 30 is made of urethane, it may be made of the same material as the pad provided inside the seat back 102. If the support member 30 is made of resin, it may be made of a soft resin such as rubber. The material of the support member 30 may be the same type with the same hardness, or multiple types with different hardnesses may be used. Furthermore, the shape and size of the support member 30 are not particularly limited.

[0031] At least one support member 30 is provided on the fixing plate 20. In the illustrated example of the present invention, two support members 30 are arranged vertically on the front surface of the back-side fixing plate 21, and two support members 30 are arranged horizontally on the upper surface of the cushion-side fixing plate 22. However, the support members 30 may be provided only on the front surface of the back-side fixing plate 21, or only on the upper surface of the cushion-side fixing plate 22. Furthermore, the number of support members 30 provided on the front surface of the back-side fixing plate 21 may be one or more, and the number of support members 30 provided on the upper surface of the cushion-side fixing plate 22 may also be one or more.

[0032] The outer layer 40 may also be called a cover. The outer layer 40 is arranged so as to cover the fixing plate 20 when viewed from the front side of the sheet 100. The outer layer 40 is made of a flexible material, for example, it is made of fiber for versatility. However, the outer layer 40 may be made of metal or resin as long as it is flexible. If the outer layer 40 is made of fiber, it may be a cloth made by knitting or weaving fibers, a nonwoven fabric, or a cloth similar to a nonwoven fabric. If the outer layer 40 is made of resin, it may be made of a soft resin such as rubber.

[0033] The upholstery 40 comprises a back-side upholstery 41 disposed on the seat back 120 side of the seat cushion 110 and seat back 120, and a cushion-side upholstery 42 disposed on the seat cushion 110 side of the seat cushion 110 and seat back 120. The back-side upholstery 41 and the cushion-side upholstery 42 are formed separately, as shown in Figures 1-4.

[0034] The back cover 41 is located in the area that supports the upper body of the seated person, and is positioned in front of the back fixing plate 21, so as to cover the back fixing plate 21 from the front.

[0035] It is desirable that the back surface 41 is positioned and held on the back fixing plate 21. The back surface 41 may (a1) be detachably attached to the back fixing plate 21 along its entire peripheral edge (all around) or along a portion of its peripheral edge, or (a2) be bonded and fixed to the back fixing plate 21 along a portion of its peripheral edge, and detachably attached to the back fixing plate 21 along at least the remaining portion of its peripheral edge.

[0036] In the case of (a2) above, the back surface 41 is joined and fixed to the upper part of the back fixing plate 21 at the upper part of the back surface 41, as shown in Figures 2 and 3, for example, and is detachable from the lower part of the back surface 41 to the lower part of the back fixing plate 21. In Figures 2 and 3, the parts that are joined and fixed are indicated by black squares, and the parts that are detachable are indicated by white squares. Furthermore, the upper part of the back surface 41 refers to the upper portion when the back surface 41 is divided into two parts vertically, and includes the upper end of the back surface 41. Also, the lower part of the back surface 41 refers to the lower portion when the back surface 41 is divided into two parts vertically, and includes the lower end of the back surface 41. Furthermore, the upper part of the back fixing plate 21 refers to the upper portion when the back fixing plate 21 is divided into two parts vertically, and includes the upper end of the back fixing plate 21. Furthermore, the lower part of the back fixing plate 21 refers to the lower portion when the back fixing plate 21 is divided into two parts vertically, and includes the lower end of the back fixing plate 21.

[0037] If the back surface 41 is detachable from the back fixing plate 21, the mounting structure is not particularly limited, but it is a mounting structure such as a fastener, button, hook-and-loop fastener, or male-female interlocking, and is designed to be less prone to misalignment with respect to the back fixing plate 21.

[0038] The cushion-side surface 42 is located in the area that supports the lower half of the seated person's body, and is positioned above the cushion-side fixing plate 22, allowing it to cover the cushion-side fixing plate 22 from above.

[0039] It is desirable that the cushion-side surface 42 is positioned and held on the cushion-side fixing plate 22. The cushion-side surface 42 may (b1) be detachably attached to the cushion-side fixing plate 22 along its entire peripheral edge (all around) or along a portion of its peripheral edge, or (b2) be bonded and fixed to the cushion-side fixing plate 22 along a portion of its peripheral edge, and detachably attached to the cushion-side fixing plate 22 along at least the remaining portion of its peripheral edge.

[0040] In the case of (b2) above, the cushion-side surface 42 is joined and fixed to the rear of the cushion-side fixing plate 22 at the rear of the cushion-side surface 42, as shown in Figures 2 and 4, for example, and is detachably attached to the front of the cushion-side fixing plate 22 at the front of the cushion-side surface 42. In Figures 2 and 4, the parts that are joined and fixed are indicated by black squares, and the parts that are detachable are indicated by white squares. The rear part of the cushion-side surface 42 refers to the rear portion when the cushion-side surface 42 is divided into two parts in the front-rear direction, and includes the rear end of the cushion-side surface 42. The front part of the cushion-side surface 42 refers to the front portion when the cushion-side surface 42 is divided into two parts in the front-rear direction, and includes the front end of the cushion-side surface 42. The rear part of the cushion-side fixing plate 22 refers to the rear portion when the cushion-side fixing plate 22 is divided into two parts in the front-rear direction, and includes the rear end of the cushion-side fixing plate 22. The front part of the cushion-side fixing plate 22 refers to the front portion when the cushion-side fixing plate 22 is divided into two parts in the front-rear direction, and includes the front end of the cushion-side fixing plate 22.

[0041] If the cushion-side surface 42 is detachable from the cushion-side fixing plate 22, the mounting structure is not particularly limited, but it is a mounting structure such as a fastener, button, hook-and-loop fastener, or male-female interlocking, and is designed to be less prone to misalignment with respect to the cushion-side fixing plate 22.

[0042] The back surface 41 and the cushion surface 42 may be used simultaneously (i) as shown in Figure 2, (ii) as shown in Figure 3, only the back surface 41 may be used and the cushion surface 42 may not be used, and (iii) as shown in Figure 4, only the cushion surface 42 may be used and the back surface 41 may not be used.

[0043] Next, the operation and effects of the embodiments of the present invention will be explained.

[0044] (A) Since there is at least one skin 40 on the side of the fixed plate 20 that is closer to the seated person, the skin 40 can cover the support member 30 that is placed on the fixed plate 20, and the support member 30 can be prevented from being exposed to the seated person. Therefore, (a) even if support members 30 are installed on the fixed plate 20, the seat portion can be made closer to a flat surface with the upholstery 40. As a result, the perception that something is attached is reduced to the human eye, and the appearance is perceived as improved. Also, (b) as shown in Figure 5, even when multiple support members 30 are installed side by side on the fixed plate 20 and grooves or steps S occur between the side by side support members 30, the upholstery 40 is interposed between the seated person and the grooves or steps S, and the upholstery 40 tends to be a continuous surface, thus reducing the feeling of discomfort a person may experience when using it.

[0045] (B) When the back side skin 41 is fixed to the upper part of the back side fixing plate 21 at the upper part of the back side skin 41, unlike (a) when the back side skin 41 is not fixed to the back side fixing plate 21, the loss of the skin 41 can be suppressed. Also, (b) when the support member 30 disposed on the back side fixing plate 21 is exposed by peeling back the back side skin 41 and adjusted in position relative to the back side fixing plate 21, the support member 30 can be covered again with the back side skin 41 simply by lowering the peeled-up skin 41 after the position of the support member 30 has been adjusted by peeling up the back side skin 41, so that the position of the support member 30 can be adjusted relatively easily even when the back side skin 41 is provided.

[0046] (C) When the back cover 41 is detachably attached to the lower part of the back fixing plate 21 at the lower part of the back cover 41, compared to when the back cover 41 is only fixed to the upper part of the back fixing plate 21 at the upper part and not detachably attached to the lower part of the back fixing plate 21 at the lower part, it is possible to suppress the displacement of the back cover 41 relative to the back fixing plate 21 due to the movement of the sitter's posture when sitting down, standing up, or when sitting down.

[0047] (D) When the back cover 41 is fixed to the upper part of the back fixing plate 21 at the top and detachable from the lower part of the back fixing plate 21 at the bottom, (i) unlike when the back cover 41 is fixed to the back fixing plate 21 at both the top and bottom, the support member 30 can be exposed by peeling back the back cover 41 and the position of the support member 30 can be adjusted relatively easily relative to the back fixing plate 21. Also, (ii) compared to when the back cover 41 is detachable from the back fixing plate 21 at both the top and bottom, the distance required to install the zipper for detachment can be shortened and the number of buttons can be reduced, reducing the effort required to attach and detach the back cover 41 to the back fixing plate 21 when adjusting the position of the support member 30, and reducing the workload when adjusting the position of the support member 30.

[0048] (E) When the cushion-side skin 42 is fixed to the rear of the cushion-side fixing plate 22 at the rear of the cushion-side skin 42, unlike (a) when the cushion-side skin 42 is not fixed to the cushion-side fixing plate 22, the loss of the skin 42 can be suppressed. Also, (b) when the support member 30 disposed on the cushion-side fixing plate 22 is exposed by peeling back the cushion-side skin 42 and adjusted in position relative to the cushion-side fixing plate 22, the support member 30 can be covered again with the cushion-side skin 42 simply by lowering the peeled-back skin 42 after the support member 30 has been positioned by peeling back the cushion-side skin 42. Therefore, even when the cushion-side skin 42 is provided, the position of the support member 30 can be adjusted relatively easily.

[0049] (F) When the cushion-side surface 42 is detachably attached to the front of the cushion-side fixing plate 22 at the front of the cushion-side surface 42, compared to when the cushion-side surface 42 is only fixed to the rear of the cushion-side fixing plate 22 at the rear and not detachably attached to the front of the cushion-side fixing plate 22 at the front, it is possible to suppress displacement of the cushion-side surface 42 relative to the cushion-side fixing plate 22 due to the movement of the sitter's posture when sitting down, standing up, or while seated.

[0050] (G) When the cushion-side outer layer 42 is fixed to the rear of the cushion-side fixing plate 22 at the rear and detachable from the front of the cushion-side fixing plate 22 at the front, (i) unlike when the cushion-side outer layer 42 is fixed to the cushion-side fixing plate 22 at both the rear and the front, the support member 30 can be exposed by peeling back the cushion-side outer layer 42, and the position of the support member 30 can be adjusted relatively easily relative to the cushion-side fixing plate 22. Also, (ii) compared to when the cushion-side outer layer 42 is detachable from the cushion-side fixing plate 22 at both the rear and the front, the distance required for fastener installation to make it detachable can be shortened, and the number of buttons can be reduced, reducing the effort required to attach and detach the cushion-side outer layer 42 to the cushion-side fixing plate 22 when adjusting the position of the support member 30, and reducing the workload when adjusting the position of the support member 30.

[0051] In the above embodiment of the present invention, a case was described in which the back side surface 41 and the cushion side surface 42 of the surface 40 are formed separately. However, as shown in Figure 6, the back side surface 41 and the cushion side surface 42 of the surface 40 may be formed integrally.
