Description

Pelvis sitting cushion for correcting spine posture.

The present invention relates to a pelvic cushion for correcting a spinal posture, and more particularly, to a pelvic cushion for correcting a vertebral posture capable of maintaining a correct spinal posture.

BACKGROUND ART Generally, a chair includes a seat plate for supporting a user's buttocks on a seat in a sitting state, a backrest which is erected on a back surface of the seat plate for supporting a back portion of a user, and a seat back and a backrest spaced apart from the ground by a predetermined height As shown in Fig. In this chair, most of the user's load is supported by the seat plate contacting with the buttocks and the thighs, and when the user sits with his / her back on the backrest, most of the load of the upper body is supported by the backrest.

The longer the sitting time in the chair is, the more the load applied to the spine is increased, resulting in a loose waist or an obstruction in the spine. In order to solve such a problem, a chair for posture correction has been developed. However, the conventional chair is focused on the improvement of the backrest structure to allow the user's upper body load to be effectively supported through the backrest. However, when the user is sitting on a chair, the user generally takes a position in which the upper body is bent forward to a certain extent, while the upper body is removed from the backrest, rather than maintaining the upper body completely in the backrest. This posture causes spinal scoliosis, headache, and so on.

Therefore, a more fundamental structure is needed to correct spinal postures.

Problems to be solved by the present invention are as follows.

First, it provides a cushion that can induce a correct spinal posture even when sitting for a long time.

Second, a chair without a backrest provides a cushion that can induce the correct spinal posture.

Fig. 1 shows the pelvis 5 of the human body. Fig. 2 shows a bony bone of a human body. Figure 3 shows the hip muscles.

1 to 3, the pelvis 5 includes two bones (innumerable bones 115 and 215), an innominate bone (sacs 115 and 215, a sacrum), and a caudal bone ), coccyx). The pelvis 5 plays an important role in walking by transmitting the weight falling down through the vertebrae 3 to the legs between the vertebrae 3 and the two legs 115 and 215.

The buttock bone 10 constitutes the lower part of the pelvis 5. The apical bone (10) is also the site where weight is put when sitting. Behind the buttock bone (10), there is a scapular bone (15) with ligaments supporting the pelvis (5), and below the scapular bone nodule (11), various muscles descending to the leg are attached. In front of the apical bone (10), the apical bony branch (13) is made and connected to the bony bone (20) to form an obturator foramen. The dorsal bone 10 forms a acetabulum with the hip 30 and the dorsal 20 to form a hip joint that forms the joint with the femur 1.

The gluteus maximus (40) pulls the back from the back with large muscles behind the pelvis (5). The gluteus maximus 40 is located between the buttock 10 and the chair when the person sits on the chair.

4 is a perspective view of a pelvis 5 cushion for correcting a spinal posture, which is an embodiment of the present invention. 5 is a perspective view of a pelvis 5 cushion for correcting a spinal posture, which is an embodiment of the present invention seen from a direction different from that of Fig. 6 is a plan view of a cushion of a pelvis 5 for calibrating a spinal posture according to an embodiment of the present invention. 7 is a perspective view of a pelvis 5 cushion for correcting a spinal posture according to another embodiment of the present invention. 8 is a perspective view of a pelvis 5 cushion for correcting a spinal posture according to another embodiment of the present invention seen from a direction different from that of Fig. 9 is a plan view of a pelvis 5 cushion for calibrating a spinal posture according to another embodiment of the present invention.

4 to 9, a pelvis 5 cushion for correcting a vertebral posture according to an embodiment of the present invention is a cushion that is disposed on the lower side of the femur bone 1 and has a height increasing from the front to the back, A pedestal 110, 210; And extends rearward from the thigh support parts 110 and 210 and is disposed under the user's buttock bone 10 (specifically, the shoulder bone isthium 11) so as to support the user's buttock bone 10 Spacers (120, 220) for receiving a plurality of spacers (11, 11); And is formed between the thigh support parts 110 and 210 and the spacers 120 and 220 and is formed in front of the user's buttock bone 10 (130, 230) in which the buttock bone nodule (11) is caught.

The thigh receiving portions 110 and 210 are inclined such that the height increases from the front to the back. The thigh support parts 110 and 210 guide the femur bone 1 to be inclined. The femur bone 1 is inclined so that the front is lower than the rear.

The spacers 120 and 220 are disposed at the rear of the thigh receiving portions 110 and 210. The spacers 120 and 220 form a space in which the scapula 10 (particularly the scapula nodule 11) is accommodated. The spacers 120 and 220 may also receive a portion of the head bone 20. The spacers 120 and 220 define a space in which the scapula 10 (particularly the scapula nodule 11) is received between the backrest of the chair and the thigh support portions 110 and 210. Spacers 120 and 220 form the spacing between the backrest of the chair and the thigh support portions 110 and 210.

The sciatica retaining jaws 130 and 230 prevent the scapula 10 (particularly the scapula nodule 11) from slipping forward. The sciatic nesting jaws 130 and 230 are disposed in front of the buttock bone 10 (particularly, the buttock bone nodule 11). It is preferable that the buttock bone 10 (particularly the buttock bone nodule 11) is located behind the ischial anchoring limbs 130 and 230.

The buttock bone 10 (particularly the buttock bone nodule 11) and the femur bone 1 can be lifted up to the upper side and slid down to the lower side due to the thigh receiving portions 110 and 210. The sciatica retaining jaws 130 and 230 fix the buttock bone 10 (particularly the buttock bone nodule 11) to prevent the pelvis 5 from slipping.

The beveling jaws 130 and 230 may have a shape bent in the direction of the spacers 120 and 220 as they are farther from the center to the side. The sciatica catching jaws 130 and 230 are concave toward the back. The sciatica retaining jaws 130 and 230 are formed to be convex toward the front side. The ischial hooking jaws 130 and 230 are curved so as to protrude forward. The right and left vertebrae 10 (particularly the buttock bone nodules 11) are arranged on the left and right sides, and the two buttock bones 10 (especially the vertebra bone nodules 11) are convex toward the front. Therefore, the sciatic hooking jaws 130 and 230 become similar to the shapes of the two buttock bones 10 (especially the buttock bone nodules 11). In addition, since the sciatic anchoring jaws 130 and 230 are configured to enclose the two buttocks 10 (in particular, the buttock bone nodules 11), the load applied to the buttocks 10 (in particular, the buttock bone nodules 11) do.

The thigh receiving portions 110 and 210 are respectively disposed at the left and right sides of the center portions 111 and 211 and the edges of the center portions 111 and 211, And V-shaped troughs 115 and 215 are formed at the boundaries between the central portions 111 and 211 and the edge portions 113 and 213, respectively.

The thigh receiving portions 110 and 210 include central portions 111 and 211 and edge portions 113 and 213, respectively. The central portions 111 and 211 and the edge portions 113 and 213 may be integrally formed. The central portions 111 and 211 are formed higher than the edge portions 113 and 213. The central portions 111 and 211 are disposed between the legs and the edge portions 113 and 213 are disposed below the crotch. Therefore, the central portions 111 and 211 function to naturally open the thighs.

According to one embodiment of the present invention, the spacers 120 are higher in height than the rear. The slope may not be constant. The inclination of the inclination may be gradually decreasing toward the rear.

The spacer 220 includes a receiving portion 221 extending rearward and downward from the sciatica catching jaw 230 to receive the user's buttock bone 10 (particularly the buttock bone nodule 11); And a support portion 223 which extends upward from the receiving portion 221 to support the gluteae maximus 40 behind the user's buttock bone 10 (especially the buttock bone nodule 11).

At least one of the receiving portion 221 and the supporting portion 223 is formed so that a portion corresponding to the back of the user's buttock bone 10 (particularly the buttock bone nodule 11) Can be.

According to another embodiment of the present invention, the spacer 220 may have a height lowered to form a space enough to accommodate the scapula 10 (in particular, the scapula nodule 11) Lt; / RTI > The receiving portion 221 is a space for receiving the scapula 10 (particularly the scapula nodule 11). The buttock bone 10 (particularly the buttock bone nodule 11) in the receptacle 221 is caught by the ischial anchoring jaw 230 and is restricted from moving forward. Therefore, the position of the pelvis 5 is fixed.

The support portion 223 is located behind the buttock bone 10 (in particular, the buttock bone nodule 11). The support portion 223 supports the gluteus maximus 40 behind the buttock bone 10 (particularly the buttock bone nodule 11). The supporting portion 223 and the receiving portion 221 may be formed such that the scapula 10 (particularly the scapula nodule 11) is inclined forward.

The receiving portion 221 may have a shape in which the height decreases from the front to the rear and the height gradually increases again. Accordingly, the rear portion of the receiving portion 221 is inclined so as to increase its height, and this inclination can make the butt bone 10 (in particular, the buttock bone nodule 11) be inclined forward.

When the buttock bone 10 (especially the buttock bone nodule 11) is tilted forward, the pelvis 5 also tilts forward. The support portion 223 supports the gluteal muscle 40 and the support portion 223 can be inclined so that the scapula 10 (especially the buttock bone nodule 11) wrapped by the gluteus maximus 40 is inclined forward.

Front seating grooves 141 and 241 are formed in the front and rear direction at the center of the scissors hooks 130 and 230. The front seating grooves 141 and 241 may be formed in the left and right osteotomies 130 and 230 and the receiving portion 221. The front seating grooves 141, 241 are formed at positions facing the genitals between the legs.

A rear seating groove 243 is formed at the center of the spacer 220 and a front seating groove 241 and a rear seating groove 243 are formed at the center of the spacer 220 and the thigh- As shown in FIG.

The rear seating groove 243 may be formed in the sciatica latching jaw 230 and the receiving portion 221. The rear seating groove 243 is formed at a position facing the genitals between the legs.

The effect of the cushion of the pelvis 5 for calibrating the spinal posture according to an embodiment of the present invention will be described as follows.

FIG. 13 is a diagram showing the relationship between a cushion of a pelvis 5 and a bony bone to correct a spinal posture, which is an embodiment of the present invention. Fig. 14 is an explanatory view of utilization of a pelvis 5 cushion for correcting a spinal posture, which is an embodiment of the present invention.

13 and 14, the thigh receiving part 110 is disposed on the lower side of the femur bone 1. Due to the inclination of the thigh support part 110, the femur bone 1 is inclined so that the rear side is higher than the front side.

The buttock bone 10 (particularly the buttock bone nodule 11) is caught by the sciatica catching jaw 130. The sciatica retaining jaw 130 prevents the scapula 10 (especially the scapula nodule 11) from slipping forward. Therefore, since the femur 1 maintains the tilted state, the pelvis 5 is also inclined, and the user can maintain his or her posture by the scissors hook 130.

The spacer 120 is formed so as to be inclined so that the height decreases from the scissors hook 130 toward the rear. Due to the inclination of the spacer 120, the pelvis 5 also tilts backward. The pelvis 5 and the vertebrae 3 are in close contact with the backrest of the chair. Therefore, the weight of the upper body of the user is dispersed as much as possible to the back of the chair, so that the user feels comfortable.

The effect of the pelvis 5 cushion for correcting the spinal posture according to another embodiment of the present invention will be described as follows.

Fig. 15 is a view showing the relation between the cushion of the pelvis 5 and the bones of the pelvis, which corrects the spinal posture, which is another embodiment of the present invention. 16 is an explanatory view of utilization of a pelvis 5 cushion for correcting a spinal posture, which is another embodiment of the present invention.

15 and 16, the thigh receiving part 210 is disposed on the lower side of the femur bone 1. Due to the inclination of the thigh receiving portion 210, the femur bone 1 is inclined so that the rear portion thereof is higher than the front portion.

The buttock bone 10 (particularly the buttock bone nodule 11) is caught by the sciatica catching jaw 230. The sciatica retaining jaw 230 prevents the scapula 10 (especially the scapula nodule 11) from slipping forward. Therefore, since the femur 1 maintains a tilted state, the pelvis 5 is kept inclined, and the user can maintain the posture by the scissors hook 230.

The spacer 220 includes a receiving portion 221 and a supporting portion 223. The support portion 223 supports the glutaeus maximus 40 behind the user's buttock 10 (in particular, the buttock nodule 11), and the receiving portion 221 and / or the support portion 223 support the gluteus maximus A slope is formed so that the pelvis 10 (particularly the buttock bone nodule 11) and the pelvis 5 are bowed forward. The upper body is tilted backward to maintain its standing, which causes the body to respond to the spine (3) to maintain an 'S' shape.

Therefore, the user can maintain the correct posture 3 even in the absence of the backrest of the chair.

The pelvic cushion for correcting a vertebral posture according to an embodiment of the present invention has a height H1 and a height H3 of the highest part of the scissors engaging jaws 130 and 230 from the ground surface and a height H1 of the lowest part of the spacers 120 and 220 The height (H2, H4) of the portion is formed at a ratio of 1: 0.8 to 1: 0.2.

Therefore, the following relationship holds.

H1: H2 = 1: 0.2 to 0.8

H2: H4 = 1: 0.2 to 0.8

When the scissors hooks 130 and 230 and the spacers 120 and 220 are formed as described above, the scapula nodule 11 is received at the appropriate depth in the spacers 120 and 220 and the scissors hooks 130 and 230 It is possible to prevent slippage of the buttock bone nodule 11.
