Japanese Patent No. 3590331

  The body support tool of Patent Document 1 described above can be formed into a seating shape suitable for the user's physique or body shape by a sheet-like covering body impregnated with a cured resin that covers the elastic body. However, since the body supporter is covered with a hardened covering, the support force to the body is enhanced, but the user cannot change the posture of the body during long-distance driving, but the same posture May be forced. In addition, when alleviating fatigue caused by maintaining the same posture, the user needs to remove the body support from the seat of the vehicle and put his back directly on the seat, and cannot continue to use the body support during driving.

  Therefore, the present invention provides a body support that can adjust the position for supporting the pelvis according to the user's physique, body shape, fatigue level, and the like, and can be used for a long time.

  Means taken to solve the above-mentioned problems are that the body support is provided on the elastic body that supports the user's pelvis when seated, the first support body provided on one of the elastic bodies, and the other elastic body. The elastic body is disposed between the first support body and the second support body, elastically deforms, and has a projecting portion projecting to the pelvis side. One end of either the first support or the second support is the lower end and the other is the upper end, the distance from the center of the protrusion to the end of the first support, and the end of the second support The distance is different.

  Moreover, the protrusion part is good to protrude by the resin elastic member of the elastomer resin provided in the inside.

  Moreover, it is good for a protrusion part to protrude by supporting a resin elastic member with the 1st urethane cloth which has an accommodating part which accommodates a part of resin elastic member, and the 2nd urethane cloth which coat | covers a resin elastic member.

  The elastic body may be formed with a plurality of protrusions by providing a plurality of resin elastic members.

  In addition, the body supporter may include a third support provided so as to sandwich at least the elastic body in a direction orthogonal to the direction in which the first support and the second support are disposed.

  According to the present invention, the body support device can prompt the user to correct the posture by pressing the user's pelvis with the elastically deforming protrusion provided on the elastic body. It is possible to suppress a force from being applied to a specific part due to the collapse of the posture. Furthermore, since the protruding portion can make the user recognize that the pelvis is being pushed, the user can increase awareness of stretching the pelvis (correcting the posture). Moreover, since the distance from the center of the protrusion to the end on the first support side and the distance from the center of the protrusion to the end on the second support side of the body support tool are different, With regard to the pelvic position shift due to the body shape or the body shape, adjustment is possible depending on the direction in which the first support and the second support are used. For example, the body support device can be adjusted to another position where the pelvis can be supported by the above method even if the posture of the user collapses during long-time use, and is always used during driving as compared with the prior art. be able to. Therefore, the body support device of the present invention can adjust the position for supporting the pelvis according to the user's physique, body shape, fatigue level, etc., and can be used for a long time.

  Moreover, since the protrusion is formed of a resin elastic member made of elastomer resin, the change in hardness due to temperature change (temperature at the place of use, heat transmitted from the user, etc.) is less than that of other elastic bodies. Therefore, the pressing feeling given to the user can be kept constant even when used for a long time.

  Further, the protruding portion accommodates a part of the resin elastic member in the accommodating portion of the first urethane cloth and covers the other portion with the second urethane cloth, so that the elastic member can be easily deformed due to the shape deformation of the urethane cloth. Since the adhesiveness with respect to the shape can be increased, the holding force is increased and the displacement of the resin elastic member can be suppressed. Furthermore, the body support device can be used in a state that matches the shape of the body by utilizing the ease of shape deformation of the urethane fabric disposed between the user and the resin elastic member.

In addition, since the elastic body has a plurality of projecting portions, the projecting portion gives a sense of acupressure against the user's pelvis, so the user is aware of stretching the pelvis (correcting the posture). The discomfort given to the user over a long period of use can be suppressed.
In addition, since the body supporter can support the user's flank portion by providing the third support body, the body support tool is elastic when the posture of the user collapses (especially when the body support tool is laterally displaced). It is possible to adjust the projecting portion to a suitable position (the position of the pelvis).

It is explanatory drawing which shows the use condition in the seat of the body support tool concerning this invention. It is a front view of the body support tool shown in FIG. It is sectional drawing of the AA cross section of the body support tool shown in FIG. It is sectional drawing of the BB cross section of the body support tool shown in FIG.

  Hereinafter, the structure of the body support device 1 according to the present invention will be described with reference to FIGS. FIG. 1 is an explanatory diagram showing a use state of the body support tool 1 according to the present invention in the seat 2, and FIG. 2 shows a front view of the body support tool 1 shown in FIG.

  As shown in FIG. 1, the body support 1 is used in a state where it is disposed between the seat 2 and the user. The body support device 1 supports the pelvis by abutting the protruding portion 3a of the body support device 1 so as to push the upper part of the pelvis of the user.

  As shown in FIG. 2, the body support 1 includes an elastic body 3 having a protrusion 3a that comes into contact with the user's pelvis, and a first support 4 and a first support 4 disposed via the elastic body 3 in the use state shown in FIG. 2 support body 5 and third support body 6 provided so as to sandwich elastic body 3 in the horizontal direction, and elastic body 3 and each support body 4, 5, 6 are sewn by sewing part 7 for sewing each. Is partitioned. The elastic body 3 has a plurality of protrusions 3a formed by an internal resin elastic member 3b (elastic member), and a predetermined distance X1 is provided between the protrusions 3a. In this embodiment, the two protrusions 3a are arranged side by side while maintaining a predetermined distance X1 (the distance between the centers of the protrusions 3a is about 130 mm) in the horizontal direction. Moreover, when using it as shown in FIG. 1 from the center O between the protrusion parts 3a shown in FIG. 2 (the center of the protrusion part 3a when there is one protrusion part 3a), the 1st support body used as an upper end or a lower end. 4 and the distance Y2 to the end 5a of the second support 5 that is the lower end or the upper end when used as shown in FIG. 1, the end of the first support 4 The distance Y1 to the portion 4a has a structure in which the distance Y2 to the end portion 5a of the second support 5 is different (Y1> Y2 in this embodiment). The above-described end portions 4a and 4b serving as the upper end and the lower end indicate portions that contact the seat or portions where the distances Y1 and Y2 are the longest from the center O between the protruding portions 3a. For example, the distance Y1 to the end 4a of the first support 4 is about 220 mm, while the distance Y2 to the end 5a of the second support 5 is about 180 mm. As a result, the body support tool 1 can be used for the elastic body 3 that supports the pelvis when the first support body 4 is used so as to be downward and when the second support body 5 is used so as to be downward. The position is different. For this reason, the body support tool 1 has a distance Y1 to the end portion 4a of the first support body 4 and a distance to the end portion 5a of the second support body 5 at a position where the protruding portion 3a presses the pelvis as shown in FIG. It can adjust according to a user's physique, a body shape, or a fatigue degree using the difference of Y2. Moreover, since the 3rd support body 6 can support a user's flank part in the use condition shown in FIG. 1 from both sides, the position adjustment of the horizontal direction (horizontal direction) of the elastic body 3 is carried out. Can do.

  Next, the internal configuration of the body support 1 according to the present invention will be described with reference to FIGS. 3 shows a cross-sectional view of the body support tool 1 shown in FIG. 2 taken along the line AA, and FIG. 4 shows a cross-sectional view of the body support tool 1 shown in FIG.

  From FIG. 3, the protruding portion 3 a of the elastic body 3 has a cylindrical resin elastic member 3 b (diameter 50 mm, height 42.5 mm) inside, and a part of the resin elastic member 3 b is the first urethane fabric 8. It is accommodated in the hole 8a (accommodating part) provided in the other part, and the other part is covered (covered) by the second urethane cloth 9 so as to protrude. The first urethane fabric 8 and the second urethane fabric 9 are bonded with an adhesive (not shown). The resin elastic member 3b is made of an elastomer resin, has a small change in hardness due to a temperature change, and is viscous. In addition, a felt 10 is provided on the first urethane fabric 8 at a bottom portion 10 a that becomes the bottom of the hole 8 a of the first urethane fabric 8. The resin elastic member 3b is held by being sandwiched between the first urethane cloth 8 and the second urethane cloth 9. At this time, the resin elastic member 3b is prevented from falling out of the hole 8a even if a force is applied to the lower side in the vertical direction in FIG. 1 due to the viscosity of the resin elastic member 3b and the ease of deformation of the urethane. Further, the body support tool 1 is sewn by the sewing unit 7 so that the first urethane fabric 8, the second urethane fabric 9, the felt fabric 10, and the fabrics 11a and 11b covering them are sandwiched between the resin elastic members 3b in the vertical direction. Since the resin elastic member 3b increases the force supported by the first urethane cloth 8 and the second urethane cloth 9, it can also increase the force for holding the position of pressing the pelvis. The body support 1 divides the elastic body 3, the first support body 4, and the second support body 5 by the sewing portion 7. The protrusion 3a has a height X2 from the backing fabric 11b on the felt fabric 10 side of the fabric covering the body support 1 to the front fabric 11a on the second urethane fabric 9 side of about 50 mm. The height X2 of the projecting portion 3a is a sensitivity that the inventor has implemented as a height that allows the user to feel that the body support device 1 is supported without causing discomfort even when the body support device 1 is used for a long time. Based on evaluation. Further, the peripheral edge of the body support 1 is reinforced while the first urethane fabric 8, the second urethane fabric 9, the felt fabric 10, and the fabrics 11a and 11b are bundled by a holding member 12 such as a tape. Since the urethane fabrics 8 and 9 are easily deformed in shape, it is possible to increase the fit for the user, and to suppress discomfort and fatigue of the user even when used for a long time. .

  4, the protrusion 3a of the elastic body 3 has two resin elastic members 3b in the horizontal direction, and this resin elastic member 3b is covered with two urethane fabrics 8 and 9 as in FIG. The two resin elastic members 3b are arranged at a predetermined interval. The body support 1 is sewn so that the first urethane cloth 8, the second urethane cloth 9, the felt cloth 10, and the cloth covering them are sandwiched between the resin elastic members 3b in the horizontal direction, and further two resin elastic members 3b. Is also sewn. The body support 1 divides the elastic body 3 and the third support 6 by the sewing portion 7. Moreover, since the elastic body 3 of the body support tool 1 is sewed to increase the force for supporting the resin elastic member 3b and at the same time the protruding portion 3a is emphasized, the pelvis is pushed against the user. Since it can be made to recognize, the user can raise awareness of stretching the pelvis (correcting posture). The distance X1 between the centers of the resin elastic members 3b (projections 3a) is about 130 mm. The distance X1 between the centers of the resin elastic members 3b is about 2 minutes, which is the average value of the waist width of adults (female in the 20s) based on the statistics of HQL (Human Life Engineering Research Center). By setting the distance so as to be 1, the projection 3a of the elastic body 3 has a sufficient distance to contact the pelvis. Further, when the user uses the body support tool 1, when the protruding portion 3 a of the elastic body 3 of the body support tool 1 comes into contact with the user's waist, the third support body 6 supports the sewing part 7 as a fulcrum. Therefore, it becomes possible to support the user's flank portion. Thereby, the body support tool 1 can adjust the protrusion part 3a of the elastic body 3 to the horizontal suitable position (position of a pelvis) with the 3rd support body 6, when a user's posture collapses. It becomes.

  The application used in the present embodiment is provided between the seat and the user when performing long-distance driving as shown in FIG. 1, and the user's pelvis is used as the protrusion 3 a of the elastic body 3. Use to push by. The body support tool 1 promotes relaxation of fatigue when holding the same posture for a long time, and the position for supporting the pelvis can be adjusted according to the user's physique, body shape, fatigue level, and the like. Moreover, since the body support tool 1 can adjust the position of the elastic body 3 with respect to the pelvis according to the orientation of the first support body 4 and the second support body 5, the posture of the body support tool 1 can be lost by driving the vehicle for a long time. Even if it is equal, it becomes possible to support the pelvis at an optimum position without removing it from the seat 2, and it can always be used during driving as compared with the prior art. Moreover, since the body support tool 1 uses the resin elastic member 3b, since there is little change in hardness due to heat change such as heat from the body or temperature change in the interior space, regardless of long-time use or season, The pressing sensation given to the user can be kept constant.
