Further, the buttocks support the infant's buttocks by the buttocks supporting the center portion in the left-right direction of the buttocks. Further, the child's knee is supported from the outside by a pair of knee support portions which are protruded from the buttocks at both ends in the left-right direction of the buttocks. [Prior Art Document] [Patent Document 1] JP-A-2007-128201 [Patent Document 2] JP-A-2007-99201 SUMMARY OF INVENTION [Problems to be Solved by the Invention] However, the inventors of the present invention As a result of continuous research, it is found that for the healthy development of infants and young children, it is necessary to properly maintain the body of the infant. This is important until 323495 4 201236904. That is, the body of the vertebrate is supported by the spine. • The supination of the spine is composed of the cervical vertebrae, the thoracic vertebrae, the lumbar vertebrae, and the sacral vertebrae (or the tailbone). On the left and right sides of the sacral vertebrae, the system is divided into ^) = wide bone, while the broad bone, sacral, and coccyx skeletons constitute the pelvis. The broad bone consists of the intestine, the ischial bone, and the pubis. In the seating order, the weight of the infant is transferred to the seat of the infant seat and supports the abone of the body of the infant. m, 疋 Therefore, as long as the bone plate of the infant in the seat for the infant is stably held in an appropriate position and posture, the position and posture of the spine can be stabilized, and the healthy development of the infant can be promoted. However, in the cushion pad as described above, the underarm support portion of the waist pad and the knee support portion of the buttock pad do not stably hold the child's bone plate, and only the buttock support portion of the buttock pad can restrict the forward movement of the child's buttocks. Make it not slip. Therefore, in the cushion of the above-mentioned "study, the body 4 of the baby is not properly maintained. The present invention has been made in view of the above circumstances, and its object is to provide an ampoule for a baby seat and for milk. In order to achieve the objective, the infant child support pad structure of the present invention has a base portion, which expands in the left-right direction and the front-rear direction, and the ischial bone. a support pad portion for supporting a ischial bone of the infant, the ischial support pad portion being formed of elastic material, and comprising two ridges disposed on the base portion in front of the left side in a left-right direction, and the left and right ridges are swelled The left and right direction of the department is more than 5 323495 201236904. The square is larger and the 4th floor of the waist is used to support the part of the breast that is above the ischial bone. The waist support is formed by elastic material. And including two ridges β' disposed in the left and right directions on the base portion, and the left and right sides of the ridges are spaced rearwardly toward the rear. According to the present invention, since the ischial branch pad portion properly maintains the ischial bone in the lower part of the pelvis of the infant, and the lumbar support portion appropriately maintains the upper part of the pelvis which is higher than the ischial bone of the infant, the bone plate of the (four) child is The spine that is held in the position and posture of the field and that extends upward from the platter is also held in the position and posture of the field. Therefore, the baby can be used in the seat and the state of the chair. The body is held in an appropriate position and posture. The ischial branch (four) and the lumbar support pad can be formed from elastic materials such as polyamine vinegar ((4) t-am) or sponge (_nge), and the elasticity is Although the (recording degree) can be the same, it is better to read the best implementation form, and the sciatic support sacral system is formed to be softer than the waist sacral sac. According to this, the morphological form can be used to The degree of freedom of the movement of the foot of the infant is obtained in a stable manner. The shape of the pair of swells of the left and right sides of the sacral sulcus is not limited as long as it extends outward in the left-right direction as it goes forward. Here, it is preferably about the left and right sides of the ischial branch; the left and right m ridges in the ridge are extended in an arc shape by enclosing the isotium accommodating space between the left and right ridges According to this embodiment, the ischial support pad portion can hold the sciatic bone of the breast more properly between the left and right ridges. 323495 6 201236904 - The left and right 1 pair of ridges of the lumbar support pad portion are oriented toward the rear - The shape of the left and right sides of the lumbar support pad portion is preferably one pair of right and left ridges between the left and right sides of the lumbar support pad portion, and the waist portion between the right and left sides is raised. According to this embodiment, the lumbar support crotch portion can more appropriately hold the portion of the pelvis which is higher than the ischial bone of the infant in the left and right pair of ridges. The shape of the raised portion of the portion is not particularly limited, and may be a fish plate shape, a crescent shape, or an elliptical shape. However, it is preferable that the raised portion of the ischial branch pad portion has a substantially semicircular shape. According to this embodiment, the shape retaining property of the ridge portion can be improved, and the ischium of the infant can be more appropriately held between the left and right sides of the ridge portion. The shape of the ridge portion of the lumbar support pad portion is not particularly limited, and may be a fish plate shape, a crescent shape, or an elliptical shape. However, it is preferable that the ridge portion of the lumbar support pad portion has a substantially semicircular shape. According to this embodiment, the shape retaining property of the ridge portion can be improved, and the portion of the pelvis which is higher than the ischial bone of the infant can be more appropriately held between the left and right ridge portions. The shape of the base portion is not particularly limited as long as it connects the ischial support potential portion and the lumbar support pad portion. For example, the shape of the base may be a rectangle extending in the left-right direction and the front-rear direction, or a circle extending in the left-right direction and the front-rear direction. Preferably, a groove for accommodating the ischial bone of the infant between the left and right anterior portions of the ischial support pad portion is formed in the base portion. According to this embodiment, since the recess is for receiving the ischial bone of the infant, the ischial support pad portion can properly hold the ischial bone of the infant to the left and right sides of the ridge. Alternatively, a groove may be formed in the base portion to accommodate the waist of the infant when the left side of the lumbar support pad portion is opposed to the ridge portion. According to this embodiment, since the recess is for receiving the waist of the infant, the waist branch can hold the waist of the infant more properly between the left and right jaws. The present invention may be provided with a sciatic support pad portion and a lumbar support pad portion. However, in a preferred embodiment, the present invention is further provided with an arrangement arranged at a position further rearward than the base portion and forming a recess for accommodating the head of the infant. Head pad. According to this embodiment, the spine of the infant can be extended in the front-rear direction without being inclined toward the left-right direction to maintain an appropriate posture. Therefore, the body of the baby can be properly held in an appropriate position and posture. [Effect of the Invention] Thus, the present invention supports the pelvis from a position close to the pelvis of the infant in the sitting position, and holds the pelvis in an appropriate position and posture. Therefore, the body of the infant in the seat will be kept in an appropriate position and posture, which can contribute to the healthy development of the infant.

The elastic thin-cut cymbal 31 having a substantially constant thickness includes a base portion 34 that expands in a direction, and the ischial cutting portion is flat and is divided into the left-right direction and the front-rear direction in the left-right direction, and is placed on the base portion 34 before being placed on the base portion 34. Two ridges; and a waist gusset pad 33, 323495 201236904 • Two ridges that are disposed in the left and right directions in the rear portion of the base portion 34. The raised portion 321 of the ischial branch pad portion 32 is disposed on the left side, and the raised portion 32m of the ischial support pad portion 32 is disposed on the right side. These two raised portions 321 and 32m are formed in a bilaterally symmetrical shape with elastic material. Further, the left-right direction of the pair of right and left raised portions 321 and 32m is larger toward the front. When the infant is seated in the seat n for the infant, the ischial bone of the infant is trapped between the left and right ridges 321 and 32 m, and the sciatic support cushion 32 is appropriately elastically deformed according to the shape of the buttocks of the infant. Gently touch the skin close to the ischial bone. Thereby, the ischial support pad portion can properly hold the ischial bone of the infant child between the raised portions M1 and 32m. The raised portion 331 of the standing lumbar support pad portion 33 is disposed on the left side, and the secret portion 33m of the waist and the support crotch portion 33 is disposed on the right side. These two ridges 331 and 33m are formed in a bilaterally symmetrical shape with elastic material. Furthermore, the distance between the ridges 331 and 33m in the left-right direction is closer to the rear. When the child is seated in the seat for the baby, the part of the pelvis that is more than the ischial bone of the baby is trapped. Between the ridges 331 and 33m, the support pad portion 33 is appropriately elastic according to the shape of the waist of the infant: eight gently contacts the skin of the bone closer to the upper part of the scia from the lateral direction. Thereby, the lumbar support crotch portion 33 can appropriately hold the portion of the pelvis which is higher than the lunar month of the infant as being between the ridges 331 and 33m. In this way, in order to enable the sciatic support pad portion 32 and the lumbar support pad portion 33 to stably maintain the pelvis of the infant and the child, the skeletal support pad can be given a degree of freedom to the two-legged motion of the infant. The portion 32 is formed to be softer than the waist support pad portion 33. In the left and right sides of the ischial branch pad portion 32 shown in Fig. 3, the right and left ridges 32r of the ridge portions 321 and 32m are encased in the ischial accommodating space between the left and right anterior portions 321 and 32m. The inside is extended in an arc shape. Thereby, the 'sciatic support pad portion 32 can hold the ischial bone of the infant child more appropriately between the raised portions 321 and 32m. In the left and right sides of the lumbar support pad portion 33 shown in Fig. 3, the right and left pair of ridges 33r of the pair of raised portions 331 and 33m are wrapped in the waist receiving space between the right and left pair of raised portions 331 and 33m. The inner method extends into an arc shape. Thereby, the lumbar support pad portion 33 can hold the pelvic portion of the upper part of the infant's ischial bone more appropriately between the raised portions 331 and 33m. The raised portions 321 and 32m of the ischial support pad portion 32 have a substantially semicircular shape. That is, the half arc portion of the outline of the left ridge portion 321 is directed to the left, and the straight portion is directed to the right. Further, the half arc portion of the outline of the right ridge portion 32 is directed to the right, and the straight portion is oriented toward the square. Thereby, the shape retention of the ridges 321, 32m is improved, and the ischium of the child can be more appropriately held between the ridges 32. When the above-mentioned left and right ridges 32 are in a straight line portion of 32 m, these left: the larger the eye-facing interval is toward the front (so-called figure-eight shape). Further, the ridge portion 331 of the waist portion of the waist portion 33 has a condensed circle shape. That is, the branch in the rim line of the raised portion 331 on the left side faces the left side, and the straight line portion faces the right side. Furthermore, the semicircular fox portion of the right side 323495 201236904 eight P 33m contour is oriented to the right, while the straight section is oriented to the left. Thereby, the shape retention of the ridges 331, 33m is improved, and y holds the pelvic portion of the nipple more than the ischial bone more appropriately between the ridges 331 and 33m. When focusing on the straight portions of the left and right ridges 331 described above, the distance between the left and right directions becomes larger toward the rear (so-called inverted figure-eight shape). Two of the base portions 34 are a pair of right and left ridge portions 32 and 32 m, and a plurality of vent holes 35 are formed. In addition, in two, there is a pair of ups and downs. A plurality of vent holes 35 are also formed between the 卩331 and 33m. The vent 35 is used to ensure ventilation of the waist of the infant. A groove portion extending in the left-right direction is formed between the ischial support pad portion 32 and the lumbar support crotch portion 33 in the upper surface of the base portion 34. The groove portion 8 functions as a fold line of the base portion 34, and functions to easily stand forward in the rear portion of the base portion 34 in a state where the front portion of the base portion 34 is horizontal. In addition, the base portion 34 of the present embodiment is formed of an elastic material, and is elastically deformed when the body weight of the infant is applied. However, in the modified example, the resin may not be elastically deformed even if the weight of the infant is not affected. Formed. For example, the base 34 can also be formed from materials that are not significantly elastic. For example, the base portion 34 is formed of a thermoplastic plastic such as polyethylene, polypr〇pylene, or methacrylic resin, or a thermosetting plastic. At this time, on the upper surface of the base portion 34, the ridge portions 321 , 32 m , 331 , and 33 m are attached to the turtle. Returning to the present embodiment, in the base portion 34, a groove 36 for accommodating the ischial bone of the infant between the left and right pair of ridges 321, 321 and 32m of the diaphysis portion 32 of the 323495 15 201236904 is formed. The groove 36 is adjacent to the ridge portion 32b and has a substantially trapezoidal shape of a substantially semicircular arc that is convex toward the rear. Since the recess 36 accommodates the ischial bone of the infant, the sciatic support pad portion 32 can hold the entire bone of the infant more appropriately between the raised portions 321, 32m. Further, in the base portion 34, a groove 37 for accommodating the waist portion of the infant between the right and left pair of raised portions 331 and 33m of the lumbar support pad portion 33 is formed. The groove 37 is adjacent to the raised portions 331, 33m and has a substantially trapezoidal shape of a substantially semicircular arc which is convex toward the front. Since the groove 37 accommodates the waist of the infant. Therefore, the waist support pad portion 33 can hold the waist of the infant child more appropriately between the raised portions 331, 33m. However, according to the present embodiment, since the ischial support pad portion 32 properly holds the ischium of the lower part of the pelvis of the infant in between the ridges 321, 32m, the lumbar support pad portion 33 connects the pelvis of the infant to the upper part of the ischial bone. The upper portion is appropriately held between the ridges 33 and 33 m, so that the pelvis of the infant is held in an appropriate position and posture, and the spine extending upward from the pelvis is also held in an appropriate position and posture. Therefore, in the chair state and the bed state of the child's seat u, the body of the infant can be maintained in an appropriate position and posture. Further, the upper portion of the pelvis which is held above the ischial bone of the infant held by the lumbar support pad portion 33 refers to the portion of the pelvis which is seated away from the seat portion 14a. That is, when the body size of the infant is relatively large, it is mainly a wide bone, but when the body shape of the infant is relatively small, it is a wide bone and an upper part of the sciatic bone. Further, according to the present embodiment, the 323495 16 201236904 is arranged at a position rearward of the base portion 34. Because the head 塾 2〗 U is used to accommodate the back of the infant, the spine of the child's spine will extend toward the front ^ ^ ^ χ ^. Moxibustion, and can be maintained in proper posture without tilting in the left and right direction. , ^ Therefore, the baby's body can be properly held in an appropriate position and posture. Although the embodiment of the present invention has been described above with reference to the drawings, the present invention is not in the form of the illustrated embodiment. The embodiment shown in the above description can be variously modified or modified in accordance with the invention. [Industrial Applicability] The infant support pad structure of the present invention can be applied to a child care device such as a baby carriage, an indoor bed, or a child seat for a vehicle.
