Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a lumbar support for maintaining correct posture in a seated state.

(Conventional technology) When sitting on a floor, tatami surface, or a chair without a backrest, the weight of the upper body is directly applied to the lumbar vertebrae, and as time passes, fatigue accumulates in the lumbar vertebrae and we gradually become slouched. This is something we experience on a daily basis, and it often has an unfavorable effect on the lumbar vertebrae and back vertebrae.

Similarly, when studying while seated in a chair, if you sit for a long time, fatigue gradually accumulates in your lumbar vertebrae and you end up leaning forward.
Furthermore, people suffering from back problems such as vertebral curvature may experience pain in their backs by continuing to sit as described above.

Therefore, a health device has been proposed in Japanese Utility Model Application Publication No. 148316/1983 that supports the lumbar vertebrae while sitting, reduces fatigue of the lumbar vertebrae, and also corrects lumbar curvature.

This proposed health tool is comprised of a support member that abuts the user's lumbar vertebrae from behind, and a pair of length-adjustable annular straps connected to the support member. When you move your knees, a tensile force is applied to the strap,
As a result, the support member presses the lumbar vertebrae from behind, thereby supporting the lumbar vertebrae.

(Problem to be solved by the invention) However, the above-mentioned health device is notable in that the support member supports the lumbar vertebrae by applying a tensile force to the straps that are stretched around the user's knees, thereby keeping the user's posture straight. Although effective and noteworthy, it requires a pair of left and right annular straps,
When the knee is moved, the left and right straps move independently and unrelated to each other, creating an imbalance in the tensile forces applied to the straps and causing the straps to come off the knee even though the lengths have been adjusted in advance.

Taking into consideration the points mentioned above, the present invention is based on the fact that the strap can be placed over both the left and right knees at once, rather than using a pair of left and right straps. The purpose is to enable the support member to support the lumbar vertebrae with force.

(Means for Solving the Problems) That is, the lumbar support device of the present invention, which satisfies the above object, includes a support member that contacts the back of the user's lumbar region and supports the lumbar region, and a support member that extends between both ends of the support member. a knee belt whose length is adjustable; and an auxiliary belt which is provided between both ends of the support member and is separate from the knee belt, is removable, and whose length is adjustable; The structure includes an insertion ring through which the auxiliary belt is inserted.

The structure according to claim 2 is more specific than the above structure, and includes an auxiliary belt that connects the knee belt to both ends of a support member, and a main belt that is removably connected to the attachment belt by a buckle member. Two knee pads are slidably attached to the inner surface of the intermediate portion of the main belt, and an auxiliary belt insertion ring is provided between the two pads.

(Function) The lumbar support having the above structure is used when the user is seated, with the support member in contact with the back of the user's lower back and the knee belt placed over the front of both knees.

At this time, when both knees are aligned, there is no particular need to use the auxiliary belt, and the auxiliary belt is removed from the buckle and left in the detached state.

When you want to create a space between your knees to support your lumbar vertebrae, put the auxiliary belt through the insertion ring, adjust the length of the knee belt according to the degree of opening of both knees, and insert it into the insertion ring. When the auxiliary belt that has been inserted is pulled, the knee belt is hung at the front of the knee at an appropriate opening angle, and the straight posture when seated is maintained by the action of the belt's tension and the action of the support member pressing the lumbar vertebrae from behind. .

(Embodiments) Hereinafter, embodiments of the present invention will be described with further reference to the accompanying drawings.

FIG. 1 shows an example of a lumbar support device according to the present invention. In the figure, 1 is a support member that comes into contact with the back of the user's lumbar region and supports the lumbar vertebrae, and 2 and 2' are both left and right ends of the support member 1. The left and right mounting belts are respectively connected to the mounting belts 2 and 2', and 3 is connected to the tips of the mounting belts 2 and 2', respectively.
The main belt is connected by buckle members 6 and 7, and together with the attachment belts 2 and 2' forms a knee belt that extends between both ends of the support member 1. The basic structure of the lumbar support device of the present invention is constituted by the knee belts 2, 3, and 2' connected between both ends of the knee belt.

Here, the support member 1 has a length that matches the width of the back of the user's waist so that it is in contact with the back of the user's waist, and usually a cushion material such as foamed plastic is stored inside the bag. It has a rigid structure that is suitable for pressing the lumbar vertebrae from the back by the tensile force of the knee belt, which will be described later.

Furthermore, the attachment belts 2, 2' and the main belt 3 are connected by male and female buckle members 6, 7 to form a series of knee belts, but as with a general buckle structure, the buckle members 6, 7 Both ends of the main belt 3 are inserted through the belt insertion holes provided on the tongue side, respectively, and the length can be adjusted at these portions.

It should be noted that this knee belt does not necessarily need to be divided into an attachment belt and a main belt, and it may be configured as one belt whose length is adjustable.

In the figure, reference numerals 4 and 5 are knee pads that are inserted through the main belt 3 and protect the knee area when the knee belt is placed around the knee. Therefore, it is designed to be held on the inner surface side of the main belt 3.

In the above configuration, the present invention further includes an auxiliary belt 9 extending between both ends of the support member 1 and having one end fixed to one end of the support member, and an attachment belt 11 extending from the other end of the support member. It is inserted into and held in a buckle 10 of an open/close type with an operating piece at the tip so that its length can be adjusted, so that it can be attached when necessary and removed when unnecessary.

Along with this, an insertion ring 8 such as a D ring is provided at an intermediate position of the knee belt, particularly between the knee pads 4 and 5, for inserting and supporting the auxiliary belt 9.

The present invention has the above-mentioned configuration, and the manner in which it is used will be explained based on FIGS. 2 and 3. In FIG. 2, the user is sitting on a chair and the auxiliary belt 9 is used. The support member 1 is in contact with the back of the lower back, and the knee belt is stretched across both knees. Then, knee pads 4 and 5 are applied to the knees to protect them.

In this manner of use, as shown in the figure, there is little space between both knees, and there are cases where both knees are used in a state where they are almost aligned.

On the other hand, FIG. 3 shows a case where a gap is placed between both knees, the auxiliary belt 9 is passed through the insertion ring 8 and bent, and the buckle 10 on the other end is attached.

In this case, the length of the knee belt is determined according to the degree of opening between the knees. For example, when sitting cross-legged, the knee belt should be loosened as much as possible, and the length of the knee belt should be increased to increase the bending angle. Try to keep it large.

By tightening the auxiliary belt 9, it becomes easier to move the knees in the open state.

In this way, the knee belt and the auxiliary belt are hung in an appropriate manner depending on the sitting state, and this applies a tensile force to the knee belt, and the supporting member is attached to the lower back and back.
In particular, the lumbar vertebrae are effectively supported by pressing the lumbar vertebrae from behind.

(Effects of the invention) As described above, the invention provides a knee belt that extends between both ends of the support member so that its length can be adjusted,
An auxiliary belt is attached separately, and the auxiliary belt is inserted through an insertion ring provided on the knee belt.By bringing the support member into contact with the back of the lower back and passing the knee belt around the knee, the knee belt can be stretched by the force of the knee. A tensile force is applied to the knee belt, and the length of the knee belt is adjusted to apply an appropriate tensile force, which presses the lumbar vertebrae from the back via the support member with an appropriate pressing force, allowing the user to continue sitting for a long time. It not only eliminates the negative effects on the lumbar vertebrae and back vertebrae, but also corrects vertebral curvature by maintaining the correct posture for a long time. be able to.

In particular, in the case of the present invention, the knee belt is a series of belts, and by adjusting the length of the belt, a tensile force can be applied that matches the degree to which the knees open. Therefore, even if the knee belt has a simple structure, the tension force can be easily adjusted by the force of the knees, and by tightening the auxiliary belt, the pressing effect on the lumbar vertebrae is even better, regardless of the degree of opening of both knees. It also has the remarkable effect of being able to accommodate various sitting postures at any time.

In addition, when the main belt is separated from the attachment belt as described in claim 2, only the main belt can be replaced, and there is an advantage that various types of belts can be used.
