Description

  The present invention relates to a sitting posture assisting device that extends a support range upward to both sides of a lower back.

Many portable seat cushions having a conventional sitting posture adjustment function are as shown in FIGS. 6 and 7, or disclosed in Patent Document 1.
The conventional portable seat cushion 40 has a plurality of penetrating through holes 41 on the surface, and a center support region 42 formed at the center of the surface of the portable seat cushion 40. The center support region 42 is a portable seat cushion. It is recessed inward from both sides of the surface of 40. Further, the portable seat cushion 40 has an opening serving as a handle portion 43 so that the user can easily carry the portable seat cushion 40 by grasping it. The portable seat cushion 40 can be further divided into a seat surface area 44 and a waist support area 45.

  In use, the portable seat cushion 40 can be placed on a seating device such as a chair and the user can sit directly on the portable seat cushion 40. Then, the center support region 42 is brought into contact with the end portion of the user's spine, and the end portion of the user's spine is supported so that the user's back is not bent naturally and straightens.

However, the above conventional ones have the following problems during actual application.
(1) The waist support region 45 and the center support region 42 are only slightly extended upward from the seat surface region 44, cannot support the lower back of the human body, and the user tilts the body back When trying to lean on the back of the chair, there is a problem that the whole tends to tilt backward and the support effect is not sufficient.
(2) Since the portable seat cushion 40 wraps only the buttocks (see Fig. 8) and cannot support the lower back of the human body, of course, the sacrum and its acupoints on both sides of the lower back cannot be pushed, Adjustment and beneficial effects are not generated, and the practical value is not high.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 1 to 4, the sitting posture assisting device 10 of the present invention includes a seat surface portion 11 and a back plate portion 12 extending upward from the rear of the seat surface portion 11.
A seat surface area 13 that gradually decreases from both sides toward the center is formed on the upper surface of the seat surface section 11, and the front end of the seat surface area 13 is curved slightly downward to form a slope 14.
Both sides of the back plate portion 12 are extended upward to form a convex portion 15, and the two convex portions 15 are raised at the center of the upper portion toward the front, and both sides are curved backward relative to each other. The working end 16 is configured to support Moreover, the notch part 17 is formed between the two convex parts 15, and the installation of the notch part 17 can keep the two convex parts 15 separated from each other.

The seat surface portion 11 and the back plate portion 12 of the sitting posture assisting device 10 are provided with a plurality of vent holes 18.
The sitting posture assisting device 10 is covered with the surface layer 20 by injection molding. The surface layer 20 is a soft pad and can be formed in various colors.

In actual use, as shown in FIG. 5, when the sitting posture assisting device 10 is placed on a seating device 30 such as a chair, the user can sit directly on the seat surface area 13 of the sitting posture assisting device 10, Both legs are smoothly extended forward by the downward curve of the slope 14, and even after the knee is bent and brought into contact with the floor, it is fully supported by the slope 14 and the contact area between the body and the sitting posture assisting device 10 can be increased. Therefore, the body is not wobbled and is supported firmly.
Further, by supporting the user's spinal end portion by installing the back plate portion 12, the back portion of the user is kept straight without being bent, and the support range is extended upward by extending the convex portion 15. The working end 16 of the convex portion 15 is brought into contact with both sides of the lower back portion, so that the effect of massage and posture correction is exerted on the portion. Furthermore, by providing the notch portion 17, the back plate portion 12 can be avoided from hitting the spine, and the convex portion 15 can be brought into full contact with the human body.

The following effects can be obtained by the structure of the specific embodiment described above.
(1) The support range is extended to the lower back by extending the convex portion 15, and when the user leans back and leans on the back of the chair, the whole can be prevented from tilting backward. The support effect is excellent.
(2) The support range is extended to the lower back by extending the convex portion 15, and the convex portion 15 pushes both sides of the lower back portion at the working end 16, and produces the effect of massage and posture correction on the relevant part, and the sitting position The posture assisting apparatus 10 exhibits a favorable beneficial action and adjustment effect on the human body, and is highly practical.

The present invention has an unprecedented structure and has industrial applicability and inventive step. In addition, the present invention has never been disclosed in any publication and has novelty, and therefore satisfies the requirements for utility model registration.
