Definitions
- the present invention relates to an attitude holding cushion provided in a seat of a baby carriage.
- a seat structure of a baby carriage there is known a seat structure in which a flat base cushion is arranged substantially all over the surface of the seat (for example, see Japanese Patent Application Laid-Open (JP-A) No. 2004-216998).
- JP-A Japanese Patent Application Laid-Open
- a cushion in which all circumferences of a flat base seat are surrounded by a projection portion or a wall portion for example, see JP-A No. 2000-296734).
- the baby carriage is easy to subject to vibration during use when compared with the baby crib used indoors. Therefore, it is desirable that an appropriate attitude holding effect is imparted to the seat so as not to shift an infant position. However, the sufficient attitude holding effect cannot be generated in the flat cushion.
- the baby carriage because shock applied to the infant is small compared with the child safety seat, the high attitude holding effect or shock cushioning effect is not required unlike the child safety seat.
- the baby carriage seat be configured such that the infant moves freely to some extent by appropriately releasing the attitude holding effect.
- the seat is formed to be able to be reclined, or the whole of baby carriage is formed to be able to be folded. In reclining the seat or in folding the baby carriage, it is necessary that the cushion be formed such that the seat can smoothly be deformed.
- an object of the invention is to provide a cushion suitable for the baby carriage.
- a cushion for the baby carriage of the present invention comprises: a lumber pad which is arranged in a lumber support region of a seat of a baby carriage; and a buttock pad which is arranged in a buttock support region of the seat, wherein the lumber pad and the buttock pad are separated from each other about a longitudinal direction of the seat, the lumber pad is configured such that an infant is supported from both sides by a pair of side support portions projecting independently from a surroundings in a mountain shape at both end portions of a right and left direction of the lumber support region, the buttock pad is configured such that a buttock of the infant is supported by a buttock support portion being projected at a center portion of the right and left direction of the buttock pad, and a knee of the infant is supported from the outside by a pair of knee support portions being projecting larger than the buttock support portion at both end portions of the right and left direction of the pad.
- the attitude of the infant can be held by supporting the buttock from both sides of the infant with the lumber pad and the buttock pad.
- the shift of the buttock toward the front of the seat can be suppressed by putting the buttock support portion to the infant buttock. Therefore, abdominal part curvature and oppression caused by the forward shift of the buttock is prevented.
- the side shift of a trunk of the infant can be prevented by supporting the infant from both sides with the pair of side support portions of the lumber pad.
- the knee support portion of the buttock pad supports the infant knee from the outside, which allows the infant knee to be properly folded inside to keep the lower extremity proper orientation, therefore, a balance between a flexor and an extensor of a lower part of the infant is properly held to prevent deformation or atrophy of the body.
- the side support portion of the lumber pad is provided so as to be projected independently from the surroundings in a mountain shape, so that a degree of freedom about the hand movement of the infant can relatively easily be enhanced.
- the lower extremity can be orientated toward an appropriate direction by putting the knee support portion of the buttock pad to the outside of the knee, it is not necessary that the infant lower extremity be surrounded over all the circumferences, and a degree of freedom about the leg movement of the infant can relatively easily be enhanced.
- the lumber pad and the buttock pad are separated from each other, so that the seat can relatively easily be deformed when it is reclined or folded.
- the side support portion is projected independently from the surroundings. Thereby, resistance to the reclining or folding of the seat is suppressed to the lower level compared with the case in which the continuous projection portion or the wall portion is formed from the lumber support region to the buttock support region.
- the pair of side support portions may be separated from each other about the right and left direction.
- the resistance can further be decreased to deform the seat more easily by separating the side support portion.
- an edge line of the buttock support portion of the buttock pad is curved about a height direction so as to draw a concave curved line whose bottom is a central portion of the right and left direction of the buttock pad.
- the edge line of the buttock support portion By imparting such curvature to the edge line of the buttock support portion, the infant lower extremity can securely be orientated toward the inside.
- the buttock support portion and the pair of knee support portions may be integrally connected, thereby a smooth curved line may be formed from the bottom of the buttock support portion to a vertex of the knee support portion.
- the buttock pad can naturally be put to the infant lower extremity to improve the infant comfort by imparting the curved line.
- the lumber pad may be provided with a first pad portion and a second pad portion which are mutually independently detachable to the seat, the first pad portion may be provided with the buttock support portion, and the second pad portion may be provided with the pair of knee support portions.
- the mode in which both the first pad portion and the second pad portion are used and the mode in which either the first pad portion or the second pad portion is used can be separated according to need.
- both the pad portions are used when a priority is given to the attitude holding effect by the buttock support portion and the knee support portion, and the unnecessary pad portion can be detached from the seat to enhance the degree of freedom for the leg movement of the infant when either the buttock support portion or the knee support portion is used.
- the cushion may comprise a head pad which is arranged in a head support region (A 1 ) of the seat.
- the infant head is kept proper attitude by providing the head pad, thereby the attitude holding effect can further be enhanced.
- it is effective to add the head pad for a baby in a lower age in month whose head is not held up.
- a neck support portion extending along a lower edge of the head pad and a pair of temporal support portions extending along both side edges of the head pad may be provided as a projection portion for supporting the infant in the head pad.
- the infant head can be held to an attitude in which a jaw of the infant is raised in some degree by supporting the infant head with the neck support portion.
- the oppression of an airway can be prevented to cause the infant to take breath without any difficulty.
- an edge line of the neck support portion may be curved about a height direction so as to draw a concave curved line whose bottom is a central portion of the right and left direction of the head pad.
- the infant rear neck can naturally be positioned in the center of the right and left direction of the head pad to prevent the side shift of the head by imparting the curvature to the neck support portion.
- an inner periphery of the temporal support portion may be provided with a support surface recessed in a cone shape.
- the temporal support portion can be fit to the temporal region of the infant to naturally orientate the head toward the front face by providing the support surface.
- An edge line of the temporal support portion is gradually lowered toward an upper edge side of the head pad. Thereby, a feeling that the head is surrounded by the temporal support portion is reduced to enhance open-feeling of the infant.
- the projection portion may not exist at least in the central portion of the upper edge of the head pad, thereby a recess portion surrounded by the projection portion may be opened to the upper edge side of the head pad. According to the embodiment, the open-feeling of the infant is enhanced because the parietal region is not constrained by the projection portion.
- At least one pad may be attached to a detachable seat cover covering the surface of the seat position-adjustably in the longitudinal direction of the seat.
- the support portion can be changed according to the infant physical body by changing the pad position. The position can easily be adjusted by attaching the pad to the seat cover.
- At least one pad may be attached to a base plate which is arranged as a core material inside the seat.
- the base plate is provided with the pad, it is not necessary to attach and detach the pad on the base plate when the seat cover is taken out from the base plate. A task for taking out the pad can be eliminated in washing the seat cover or the like.
- the pad attached to the base plate may be adjustable in position for the longitudinal direction of the seat.
- infant shall include a wide range of a baby stage to a school age unless otherwise noted.

- the base seat 31 is formed in the flat shape like the base seat 11 of the head pad 10 .
- Each side support portion 32 is provided so as to project independently from the surroundings in a mountain shape. That is, the side support portion 32 is formed as a projection in which the altitude is gradually decreased from the vertex 32 a toward all the directions, the side support portion 32 does not intersect the other projection portion, and an outer periphery 32 b draws a closed loop on the surface of the base seat 31 .
- the outer periphery 32 b may be formed in various shapes such as a circle, an oval, an ellipse, a barrel shape, and an egg shape. As shown by broken lines in FIGS. 9 and 10 , the surface of the side support portion 32 is curved so as to draw a convex curve line. As shown in FIG. 8 , a concave portion 31 a is formed in the central portion of the lower edge of the base seat 31 so as to intrude into the upper edge side of the lumber pad 30 from the outer periphery 32 b of the side support portion 32 . By providing the concave portion 31 a, resistance imparted by the lumber pad 30 , when the seat 3 is folded in right and left direction, can be decreased.
- concave portions 33 are provided in the base seat 31 . While the concave portion 33 functions as a positioning portion which prevent the shift of a back portion or the lumber of the infant, the concave portion 33 performs the function of generating a gap between the back portion or lumber of the infant and the base seat 31 to ensure air flow. Air holes 33 a are made in the concave portion 33 . Instead of the air holes 33 a, the bottom surface of the concave portion 33 may be made of a mesh material having the excellent aeration property. A pair of hooks 34 and a belt through hole 35 are also provided in the base seat 31 .

- FIGS. 11 to 14 show the detail of the buttock pad 50 .
- the buttock pad 50 includes a base seat 51 and a projection portion 52 extended in the right and left direction on the base seat 51 .
- the base seat 51 is formed in the flat shape like the base seats 11 and 31 of the head pad 10 and lumber pad 30 .
- the projection portion 52 comprises a buttock support portion 53 and a pair of knee support portions 54 arranged in both end portions of the buttock support portion 53 .
- the buttock support portion 53 is provided to support an infant buttock
- the knee support portion 54 is provided to support an infant knee from the side.
- the buttock support portion 53 and the knee support portion 54 are integrally connected.
- an edge line 53 a of the buttock support portion 53 is curved in the height direction (thickness direction of the buttock pad 50 ) so as to draw a concave curved line whose bottom becomes the center portion in the right and left direction of the buttock pad 50 .
- each knee support portion 54 is projected from the base seat 51 in a mountain shape like the side support portion 32 of the lumber pad 30 .
- the projection amount of the knee support portion 54 is larger than that of the buttock support portion 53 .
- the surface of the knee support portion 54 is extended from a vertex 54 a toward an outer periphery 54 b of the knee support portion 54 drawing the convex curved line.
- An edge line 53 a of the buttock support portion 53 is integrally connected to the surfaces of the knee support portions 54 on both sides, and thereby the smooth curved line is formed from the center of the buttock support portion 53 to a vertex 54 a of the knee support portion 54 .
- a pair of support surface 53 b which accepts the infant buttocks is provided in the side face of the buttock support portion 53 .
- the support surface 53 b is formed in the concave curved surface like the cone-shape so as to fit to the infant buttock, more particularly to the surface of a diaper attached to the buttock.
- the dimensions such as the height of the projection portion 52 and the inclined angle of the support surface 53 b can appropriately be determined according to the physical size of the infant which is of the target of the baby carriage 1 .
- the height of the buttock support portion 53 is set to a level such that the buttock support portion 53 can accept the infant buttock and, at the same time, such that an infant lower extremity can naturally surmount the buttock support portion 53 .
- the height and position of the knee support portion 54 is set such that the knee support portion 54 comes into contact with the infant knee from the outside and, at the same time, such that the knee does not exceed the vertex 54 a of the knee support portion 54 to slip to the outside in the right and left direction.
- the center height of the buttock support portion 53 can be set at about 20 mm, the height of the vertex 54 a can be set at about 33 mm, the distance between the vertexes 54 a can be set at about 160 mm, and the inclined angle can be set in the range of about 45° to 60° with respect to the horizontal direction of the support surface 53 b.
- the action of the cushion will be described below.
- the infant occipital region is accepted and supported by recess portion 15 .
- the neck support portion 13 of the head pad 10 is put to the rear neck of an infant 100 to support the neck portion from the back. Therefore, a head 101 of the infant 100 is held to an attitude in which a jaw of the infant 100 is raised in some degree, and the oppression of an airway can be prevented to cause the infant 100 to take breath without any difficulty. Because the edge line 13 a of the neck support portion 13 is curved drawing the concave curved line as shown in FIGS.
- the neck portion of the infant 100 can naturally be positioned to the center in the right and left direction.
- the head 101 is supported by the support surfaces 14 b of the temporal support portion 14 from both sides, the head 101 is naturally orientated toward the front face to prevent the side toppling and side shift of the head 101 .
- These actions are particularly effective to a baby before a baby head is held up.
- the temporal support portion 14 is gradually decreased toward the upper edge of the head pad 10 , a feeling that the head 101 is surrounded by the temporal support portion 14 is reduced to enhance the open-feeling.
- the projection portion 12 is provided up to both side edges and the recess portion 15 is opened to the upper edge side of head pad 10 , so that there is no fear that the parietal region is excessively constrained by the projection portion 12 . Accordingly the open-feeling is enhanced in the infant.
- the side support portion 32 of the lumber pad 30 is put to a flank 102 of the infant 100 to support the flank 102 from the outside, which prevents the side shift of a trunk of the infant 100 . Because the side support portion 32 is projected in a mountain shape, the feeling that the flank 102 is surrounded by the side support portion 32 is reduced to enhance the open-feeling. Because the projection portion or the wall portion does not exist around a shoulder of the infant 100 , the movement of an infant arm is not obstructed.
- the support surface 53 b of the buttock support portion 53 is put to a buttock 103 of the infant 100 to support the buttock 103 .
- the shift of the infant 100 toward the front of the seat 3 is suppressed.
- the buttock 103 of the infant 100 is never shifted toward the front. Accordingly, abdominal part curvature and oppression caused by the forward shift of the buttock is not generated.
- the knee support portion 54 supports a knee 104 of the infant 100 so as to come into contact with the knee 104 from the outside, which allows the knee 104 to be properly folded inside. Thereby, the opening of the knee 104 toward the outside is suppressed and a lower extremity 105 is held in a proper direction.
- the edge line 53 a of the buttock support portion 53 is merged with the surface of the knee support portion 54 with the edge line 53 a curving so as to draw the concave curved line, so that the lower extremity 105 can be orientated more stably toward the inside.
- the buttock pad 50 is configured such that the lower extremity 105 exceeds the buttock support portion 53 to stretch out the lower extremity 105 toward the front of the seat 3 , and the projection portion or wall portion which surrounds the lower extremity 105 does not exist. Therefore, the movement of infant legs is not obstructed.
- the cushion 5 of the embodiment because the lumber pad 30 and the buttock pad 50 are individually provided as mutually separated parts, therefore, when the inclination of the back portion of the seat 3 is change making the bending line L 1 (see FIG. 2 ) between the lumber support region A 2 and the buttock support region A 3 as an axis, or when the seat 3 is folded along the bending line L 1 , the cushion 5 does not become the resistance, and the reclining operation or folding operation of the seat 3 can be relatively easily performed.
- the lumber pad 30 is configured such that the infant 100 is supported from both sides by the pair of mountain-shaped side support portions 32 arranged at the both end portions of the right and left direction, the resistance of the cushion 5 to the reclining operation or folding operation of the seat 3 can be decreased to a lower level comparing with the case in which the continuous projection portion or wall portion is provided from the lumber support region A 2 to the buttock support region A 3 .
- FIG. 18 shows a modification in which the lumber pad 30 is changed.
- the base seat 31 of the lumber pad 30 is omitted, and only the pair of side support portions 32 is provided in the lumber pad 30 . That is, the pair of side support portions 32 are not coupled to each other by the base seat 31 , but are separated from each other in the right and left direction.
- the resistance of the cushion 5 is further decreased, which allows the seat 3 to be deformed more easily and smoothly.
- FIG. 19 shows a modification in which the buttock pad 50 is changed.
- the buttock pad 50 includes a first pad portion 50 A and a second pad portion 50 B which can be separated from each other.
- the buttock support portion 53 is provided in the first pad portion 50 A
- the knee support portion 54 is provided in the second pad portion 50 B.

The lumber pad is configured to support an infant from both sides by a pair of side support portions projecting independently from surroundings in mountain-shape at both ends of width direction of the lumber support region. The buttock pad is configured to support a buttock of the infant by a buttock support portion projected at a center of the width direction of the buttock pad, a knee is supported from the outside by a pair of knee support portions projecting larger than the buttock support portion at both ends of the width direction.
Description
- 1. Field of the Invention
- The present invention relates to an attitude holding cushion provided in a seat of a baby carriage.
- 2. Description of the Related Art
- For a seat structure of a baby carriage, there is known a seat structure in which a flat base cushion is arranged substantially all over the surface of the seat (for example, see Japanese Patent Application Laid-Open (JP-A) No. 2004-216998). For the cushion used in an automobile child seat or a baby crib, there is also proposed a cushion in which all circumferences of a flat base seat are surrounded by a projection portion or a wall portion (for example, see JP-A No. 2000-296734).
- Because a baby carriage is used to carry an infant out of doors, the baby carriage is easy to subject to vibration during use when compared with the baby crib used indoors. Therefore, it is desirable that an appropriate attitude holding effect is imparted to the seat so as not to shift an infant position. However, the sufficient attitude holding effect cannot be generated in the flat cushion. In the baby carriage, because shock applied to the infant is small compared with the child safety seat, the high attitude holding effect or shock cushioning effect is not required unlike the child safety seat. On the contrary, it is desirable that the baby carriage seat be configured such that the infant moves freely to some extent by appropriately releasing the attitude holding effect. In many baby carriages, the seat is formed to be able to be reclined, or the whole of baby carriage is formed to be able to be folded. In reclining the seat or in folding the baby carriage, it is necessary that the cushion be formed such that the seat can smoothly be deformed.
- In view of the foregoing, an object of the invention is to provide a cushion suitable for the baby carriage.
- In order to achieve the object a cushion for the baby carriage of the present invention comprises: a lumber pad which is arranged in a lumber support region of a seat of a baby carriage; and a buttock pad which is arranged in a buttock support region of the seat, wherein the lumber pad and the buttock pad are separated from each other about a longitudinal direction of the seat, the lumber pad is configured such that an infant is supported from both sides by a pair of side support portions projecting independently from a surroundings in a mountain shape at both end portions of a right and left direction of the lumber support region, the buttock pad is configured such that a buttock of the infant is supported by a buttock support portion being projected at a center portion of the right and left direction of the buttock pad, and a knee of the infant is supported from the outside by a pair of knee support portions being projecting larger than the buttock support portion at both end portions of the right and left direction of the pad.
- According to the cushion of the invention, the attitude of the infant can be held by supporting the buttock from both sides of the infant with the lumber pad and the buttock pad. The shift of the buttock toward the front of the seat can be suppressed by putting the buttock support portion to the infant buttock. Therefore, abdominal part curvature and oppression caused by the forward shift of the buttock is prevented. The side shift of a trunk of the infant can be prevented by supporting the infant from both sides with the pair of side support portions of the lumber pad. Further, the knee support portion of the buttock pad supports the infant knee from the outside, which allows the infant knee to be properly folded inside to keep the lower extremity proper orientation, therefore, a balance between a flexor and an extensor of a lower part of the infant is properly held to prevent deformation or atrophy of the body. The side support portion of the lumber pad is provided so as to be projected independently from the surroundings in a mountain shape, so that a degree of freedom about the hand movement of the infant can relatively easily be enhanced. Because the lower extremity can be orientated toward an appropriate direction by putting the knee support portion of the buttock pad to the outside of the knee, it is not necessary that the infant lower extremity be surrounded over all the circumferences, and a degree of freedom about the leg movement of the infant can relatively easily be enhanced. Further, the lumber pad and the buttock pad are separated from each other, so that the seat can relatively easily be deformed when it is reclined or folded. In addition, the side support portion is projected independently from the surroundings. Thereby, resistance to the reclining or folding of the seat is suppressed to the lower level compared with the case in which the continuous projection portion or the wall portion is formed from the lumber support region to the buttock support region.
- According to one embodiment of the present invention, the pair of side support portions may be separated from each other about the right and left direction. In folding the seat in the right and left direction, the resistance can further be decreased to deform the seat more easily by separating the side support portion.
- According to one embodiment of the present invention, an edge line of the buttock support portion of the buttock pad is curved about a height direction so as to draw a concave curved line whose bottom is a central portion of the right and left direction of the buttock pad. By imparting such curvature to the edge line of the buttock support portion, the infant lower extremity can securely be orientated toward the inside. Further the buttock support portion and the pair of knee support portions may be integrally connected, thereby a smooth curved line may be formed from the bottom of the buttock support portion to a vertex of the knee support portion. The buttock pad can naturally be put to the infant lower extremity to improve the infant comfort by imparting the curved line.
- According to one embodiment of the present invention, the lumber pad may be provided with a first pad portion and a second pad portion which are mutually independently detachable to the seat, the first pad portion may be provided with the buttock support portion, and the second pad portion may be provided with the pair of knee support portions. In this case, the mode in which both the first pad portion and the second pad portion are used and the mode in which either the first pad portion or the second pad portion is used can be separated according to need. For example, both the pad portions are used when a priority is given to the attitude holding effect by the buttock support portion and the knee support portion, and the unnecessary pad portion can be detached from the seat to enhance the degree of freedom for the leg movement of the infant when either the buttock support portion or the knee support portion is used.
- According to one embodiment of the present invention, the cushion may comprise a head pad which is arranged in a head support region (A1) of the seat. The infant head is kept proper attitude by providing the head pad, thereby the attitude holding effect can further be enhanced. Particularly it is effective to add the head pad for a baby in a lower age in month whose head is not held up.
- A neck support portion extending along a lower edge of the head pad and a pair of temporal support portions extending along both side edges of the head pad may be provided as a projection portion for supporting the infant in the head pad. According to the embodiment, the infant head can be held to an attitude in which a jaw of the infant is raised in some degree by supporting the infant head with the neck support portion. Thereby, the oppression of an airway can be prevented to cause the infant to take breath without any difficulty. By putting the temporal support portion to the infant head from the side, the side toppling and side shift of the head are prevented, thus the infant head can be orientated toward the front face.
- In above embodiment, an edge line of the neck support portion may be curved about a height direction so as to draw a concave curved line whose bottom is a central portion of the right and left direction of the head pad. The infant rear neck can naturally be positioned in the center of the right and left direction of the head pad to prevent the side shift of the head by imparting the curvature to the neck support portion.
- In above embodiment, an inner periphery of the temporal support portion may be provided with a support surface recessed in a cone shape. The temporal support portion can be fit to the temporal region of the infant to naturally orientate the head toward the front face by providing the support surface.
- An edge line of the temporal support portion is gradually lowered toward an upper edge side of the head pad. Thereby, a feeling that the head is surrounded by the temporal support portion is reduced to enhance open-feeling of the infant.
- Further, the projection portion may not exist at least in the central portion of the upper edge of the head pad, thereby a recess portion surrounded by the projection portion may be opened to the upper edge side of the head pad. According to the embodiment, the open-feeling of the infant is enhanced because the parietal region is not constrained by the projection portion.
- According to one embodiment of the present invention, at least one pad may be attached to a detachable seat cover covering the surface of the seat position-adjustably in the longitudinal direction of the seat. In the embodiment, the support portion can be changed according to the infant physical body by changing the pad position. The position can easily be adjusted by attaching the pad to the seat cover.
- Alternatively, at least one pad may be attached to a base plate which is arranged as a core material inside the seat. In the case the base plate is provided with the pad, it is not necessary to attach and detach the pad on the base plate when the seat cover is taken out from the base plate. A task for taking out the pad can be eliminated in washing the seat cover or the like. The pad attached to the base plate may be adjustable in position for the longitudinal direction of the seat.
- As used herein, the term of infant shall include a wide range of a baby stage to a school age unless otherwise noted.

baby carriage 1 includes a baby carriagemain body 2 and aseat 3. The baby carriagemain body 2 has a frame structure in which pipe materials are appropriately combined, and theseat 3 is attached to the baby carriagemain body 2. The baby carriagemain body 2 is configured to be able to be folded in a back and forth direction and in a right and left direction, and theseat 3 is configured to be able to be reclined. A folding mechanism and a reclining mechanism of thebaby carriage 1 are similar to those of the well-known baby carriage. -
FIG. 2 is a plan view of theseat 3. Theseat 3 has a structure in which a base plate (not shown) made of an elastic material such as resin is covered with aseat cover 4. Theseat 3 can be folded along a bending line L1. Theseat cover 4 can be detached from the base plate. The seat cover 4A is provided with acushion 5. Thecushion 5 includes ahead pad 10, alumber pad 30, and abuttock pad 50. Thehead pad 10 is arranged in a head support region A1 of theseat 3, thelumber pad 30 is arranged in a lumber support region A2 of theseat 3, and thebuttock pad 50 is arranged in a buttock support region A3 of theseat 3. Thesepads head pad 10 and thelumber pad 30 are coupled to each other. On the other hand, thelumber pad 30 and thebuttock pad 50 are attached to theseat cover 4 while separated from each other in a longitudinal direction (vertical direction ofFIG. 2 ) of theseat 3 across the bending line L1. - FIGS. 3 to 7 show the detail of the
head pad 10. As shown inFIGS. 3 and 4 , thehead pad 10 comprises abase seat 11 and aprojection portion 12 provided along an outer periphery of thebase seat 11. Thebase seat 11 is formed in a flat shape having round shaped outer periphery. Theprojection portion 12 comprises aneck support portion 13 and a pair oftemporal support portions 14. Theneck support portion 13 is extended along a lower edge of thehead pad 10, and the pair oftemporal support portions 14 is extended along both side edges of thehead pad 10. Theneck support portion 13 is provided to support the rear neck of the infant, and thetemporal support portion 14 is provided to support the head of the infant from the side. Theneck support portion 13 and thetemporal support portion 14 are integrally connected. Thetemporal support portion 14 is terminated at a position where thetemporal support portion 14 substantially reaches an upper edge of thehead pad 10, and theprojection portion 12 does not exist in at least the center of the upper edge of thehead pad 10. Thereby, arecess portion 15 is generated on thebase seat 11. In therecess portion 15, the lower edge and side edges are surrounded by theprojection portion 12, and the upper edge is opened. Therecess portion 15 functions as a portion which accepts an occipital region of the infant. - As shown by broken lines in
FIGS. 5 and 6 , anedge line 13 a of theneck support portion 13 is curved in a height direction (thickness direction of the head pad 10) so as to draw a concave curved line whose bottom is a center portion in the right and left direction of thehead pad 10. On the other hand, as can be seen fromFIG. 7 , anedge line 14 a of thetemporal support portion 14 is inclined so as to be gradually lowered from the lower edge of thehead pad 10 toward the upper edge side (left inFIG. 7 ). A front end of thetemporal support portion 14 has the substantially same height as thebase seat 11. Accordingly, theprojection portion 12 has avertex 12 a at a boundary position between theneck support portion 13 and thetemporal support portion 14, and the height of theprojection portion 12, i.e., an amount of projection from thebase seat 11 is decreased as theprojection portion 12 is separated away from thevertex 12 a along the edge lines 13 a and 14 a. - As shown by hatch lines in FIGS. 3 to 5, a
support surface 14 b which is recessed in a bowl shape is provided in an inner periphery of thetemporal support portion 1, i.e., a region located inside theedge line 14 a. Thesupport surface 14 b functions as an inclined surface which laterally supports the infant head accepted in therecess portion 15. Pluralconcave portions 16 are provided in abottom surface 15 a of therecess portion 15. While theconcave portion 16 functions as a positioning portion which suppresses the shift of the infant occipital region, theconcave portion 16 performs the function of generating a gap between the infant occipital region and thebase seat 11 to ensure air flow. Air holes 16 a are made in theconcave portion 16. Instead of the air holes 16 a, the bottom surface of theconcave portion 16 may be made of a mesh material having the excellent aeration property. - Dimensions of each portion such as the height of the
projection portion 12, the inclined angle of thesupport surface 14 b, and a size of therecess portion 15 can appropriately be determined according to a physical size of the infant which is of the target of thebaby carriage 1. However, desirably the height of theneck support portion 13 is adjusted to the projection amount of the occipital region based on the infant rear neck, and desirably a width of therecess portion 15 is adjusted to the size of the occipital region. Only as a guide, based on the surface of thebase seat 11, i.e., thebottom surface 15 a of therecess portion 15, the center height of theneck support portion 13 can be set at about 10 mm, the height of thevertex 12 a of theprojection portion 12 can be set at about 20 mm, and the inclined angle can be set at about 45° with respect to a horizontal direction of thesupport surface 14 b. Thebottom surface 15 a of therecess portion 15 can be provided such that a circular region having a diameter of about 100 mm is ensured. An elastic material having a proper aeration property may be provided as an interior material in thehead pad 10. The elastic material such as cotton, urethane, low-repulsion urethane, and gel can be used as the interior material. The interior material maybe provided only in theprojection portion 12, or the interior material may be provided in both thebase seat 11 and theprojection portion 12. - FIGS. 8 to 10 show the detail of the
lumber pad 30. Thelumber pad 30 comprises abase seat 31 and a pair ofside support portions 32 arranged in both end portions in the right and left direction of the lower edge of thebase seat 31. Thebase seat 31 is formed in the flat shape like thebase seat 11 of thehead pad 10. Eachside support portion 32 is provided so as to project independently from the surroundings in a mountain shape. That is, theside support portion 32 is formed as a projection in which the altitude is gradually decreased from thevertex 32 a toward all the directions, theside support portion 32 does not intersect the other projection portion, and anouter periphery 32 b draws a closed loop on the surface of thebase seat 31. Theouter periphery 32 b may be formed in various shapes such as a circle, an oval, an ellipse, a barrel shape, and an egg shape. As shown by broken lines inFIGS. 9 and 10 , the surface of theside support portion 32 is curved so as to draw a convex curve line. As shown inFIG. 8 , aconcave portion 31 a is formed in the central portion of the lower edge of thebase seat 31 so as to intrude into the upper edge side of thelumber pad 30 from theouter periphery 32 b of theside support portion 32. By providing theconcave portion 31 a, resistance imparted by thelumber pad 30, when theseat 3 is folded in right and left direction, can be decreased. - Plural
concave portions 33 are provided in thebase seat 31. While theconcave portion 33 functions as a positioning portion which prevent the shift of a back portion or the lumber of the infant, theconcave portion 33 performs the function of generating a gap between the back portion or lumber of the infant and thebase seat 31 to ensure air flow. Air holes 33 a are made in theconcave portion 33. Instead of the air holes 33 a, the bottom surface of theconcave portion 33 may be made of a mesh material having the excellent aeration property. A pair ofhooks 34 and a belt throughhole 35 are also provided in thebase seat 31. The pair ofhook 34 is a coupling tool which couples thehead pad 10 and thelumber pad 30, and the belt throughhole 35 attaches thelumber pad 30 to theseat cover 4. A hook (not shown) which can engage thehook 34 is provided in the backside of thehead pad 10. A method of utilizing thehook 34 and the belt throughhole 35 to attach thelumber pad 30 will be described later. - The size of the
side support portion 32 can appropriately be determined according to the physical size of the infant which is of the target of thebaby carriage 1. However, desirably the size and position of theside support portion 32 are adjusted so as to be able to properly support the infant from the side. Only as a guide, based on the surface of thebase seat 31, the height of thevertex 32 a of theprojection portion 32 can be set at about 15 mm, a distance between thevertexes 32 a can be set in the range of about 100 mm to about 150 mm, and the inclined angle can be set at about 45° with respect to the horizontal direction of the surface of theside support portion 32. An elastic material having a proper aeration property may be provided as the interior material in thelumber pad 30. The elastic material such as cotton, urethane, low-repulsion urethane, and gel can be used as the interior material. The interior material may be provided only in theside support portion 32, or the interior material may be provided in both thebase seat 31 and theside support portion 32. - FIGS. 11 to 14 show the detail of the
buttock pad 50. Thebuttock pad 50 includes abase seat 51 and aprojection portion 52 extended in the right and left direction on thebase seat 51. Thebase seat 51 is formed in the flat shape like the base seats 11 and 31 of thehead pad 10 andlumber pad 30. Theprojection portion 52 comprises abuttock support portion 53 and a pair ofknee support portions 54 arranged in both end portions of thebuttock support portion 53. Thebuttock support portion 53 is provided to support an infant buttock, and theknee support portion 54 is provided to support an infant knee from the side. Thebuttock support portion 53 and theknee support portion 54 are integrally connected. - As shown by the broken line in
FIG. 13 , anedge line 53 a of thebuttock support portion 53 is curved in the height direction (thickness direction of the buttock pad 50) so as to draw a concave curved line whose bottom becomes the center portion in the right and left direction of thebuttock pad 50. On the other hand, as can be seen from FIGS. 11 to 13, eachknee support portion 54 is projected from thebase seat 51 in a mountain shape like theside support portion 32 of thelumber pad 30. The projection amount of theknee support portion 54 is larger than that of thebuttock support portion 53. As can be seen fromFIG. 14 , the surface of theknee support portion 54 is extended from avertex 54 a toward anouter periphery 54 b of theknee support portion 54 drawing the convex curved line. Anedge line 53 a of thebuttock support portion 53 is integrally connected to the surfaces of theknee support portions 54 on both sides, and thereby the smooth curved line is formed from the center of thebuttock support portion 53 to avertex 54 a of theknee support portion 54. - As shown by hatch lines in
FIGS. 11 and 12 , a pair ofsupport surface 53 b which accepts the infant buttocks is provided in the side face of thebuttock support portion 53. Thesupport surface 53 b is formed in the concave curved surface like the cone-shape so as to fit to the infant buttock, more particularly to the surface of a diaper attached to the buttock. - The dimensions such as the height of the
projection portion 52 and the inclined angle of thesupport surface 53 b can appropriately be determined according to the physical size of the infant which is of the target of thebaby carriage 1. However, desirably the height of thebuttock support portion 53 is set to a level such that thebuttock support portion 53 can accept the infant buttock and, at the same time, such that an infant lower extremity can naturally surmount thebuttock support portion 53. Desirably, the height and position of theknee support portion 54 is set such that theknee support portion 54 comes into contact with the infant knee from the outside and, at the same time, such that the knee does not exceed thevertex 54 a of theknee support portion 54 to slip to the outside in the right and left direction. Only as a guide, based on the surface of thebase seat 51, the center height of thebuttock support portion 53 can be set at about 20 mm, the height of thevertex 54 a can be set at about 33 mm, the distance between thevertexes 54 a can be set at about 160 mm, and the inclined angle can be set in the range of about 45° to 60° with respect to the horizontal direction of thesupport surface 53 b. - When the infant is laid down on or seated in the
seat 3, the action of the cushion will be described below. In the head support region A1 (seeFIG. 2 ) on theseat 3, the infant occipital region is accepted and supported byrecess portion 15. In this case, as shown inFIG. 15A , theneck support portion 13 of thehead pad 10 is put to the rear neck of aninfant 100 to support the neck portion from the back. Therefore, ahead 101 of theinfant 100 is held to an attitude in which a jaw of theinfant 100 is raised in some degree, and the oppression of an airway can be prevented to cause theinfant 100 to take breath without any difficulty. Because theedge line 13 a of theneck support portion 13 is curved drawing the concave curved line as shown inFIGS. 5 and 6 , the neck portion of theinfant 100 can naturally be positioned to the center in the right and left direction. As shown inFIG. 15B , because thehead 101 is supported by the support surfaces 14 b of thetemporal support portion 14 from both sides, thehead 101 is naturally orientated toward the front face to prevent the side toppling and side shift of thehead 101. These actions are particularly effective to a baby before a baby head is held up. Because thetemporal support portion 14 is gradually decreased toward the upper edge of thehead pad 10, a feeling that thehead 101 is surrounded by thetemporal support portion 14 is reduced to enhance the open-feeling. Theprojection portion 12 is provided up to both side edges and therecess portion 15 is opened to the upper edge side ofhead pad 10, so that there is no fear that the parietal region is excessively constrained by theprojection portion 12. Accordingly the open-feeling is enhanced in the infant. - In the lumber support region A2 of the
seat 3, as shown inFIG. 16 , theside support portion 32 of thelumber pad 30 is put to aflank 102 of theinfant 100 to support theflank 102 from the outside, which prevents the side shift of a trunk of theinfant 100. Because theside support portion 32 is projected in a mountain shape, the feeling that theflank 102 is surrounded by theside support portion 32 is reduced to enhance the open-feeling. Because the projection portion or the wall portion does not exist around a shoulder of theinfant 100, the movement of an infant arm is not obstructed. - In the buttock support region A3 of the
seat 3, as shown inFIG. 17 , thesupport surface 53 b of thebuttock support portion 53 is put to abuttock 103 of theinfant 100 to support thebuttock 103. Thereby the shift of theinfant 100 toward the front of theseat 3 is suppressed. Particularly, even in the case of the attitude in which the back of theseat 3 is raised to seat theinfant 100, thebuttock 103 of theinfant 100 is never shifted toward the front. Accordingly, abdominal part curvature and oppression caused by the forward shift of the buttock is not generated. - The
knee support portion 54 supports aknee 104 of theinfant 100 so as to come into contact with theknee 104 from the outside, which allows theknee 104 to be properly folded inside. Thereby, the opening of theknee 104 toward the outside is suppressed and alower extremity 105 is held in a proper direction. In addition, theedge line 53 a of thebuttock support portion 53 is merged with the surface of theknee support portion 54 with theedge line 53 a curving so as to draw the concave curved line, so that thelower extremity 105 can be orientated more stably toward the inside. By these functions, the balance between a flexor and an extensor of a lower part of theinfant 100 is properly held to prevent the deformation or atrophy of the body. Thebuttock pad 50 is configured such that thelower extremity 105 exceeds thebuttock support portion 53 to stretch out thelower extremity 105 toward the front of theseat 3, and the projection portion or wall portion which surrounds thelower extremity 105 does not exist. Therefore, the movement of infant legs is not obstructed. - In the
cushion 5 of the embodiment, because thelumber pad 30 and thebuttock pad 50 are individually provided as mutually separated parts, therefore, when the inclination of the back portion of theseat 3 is change making the bending line L1 (seeFIG. 2 ) between the lumber support region A2 and the buttock support region A3 as an axis, or when theseat 3 is folded along the bending line L1, thecushion 5 does not become the resistance, and the reclining operation or folding operation of theseat 3 can be relatively easily performed. Furthermore, thelumber pad 30 is configured such that theinfant 100 is supported from both sides by the pair of mountain-shapedside support portions 32 arranged at the both end portions of the right and left direction, the resistance of thecushion 5 to the reclining operation or folding operation of theseat 3 can be decreased to a lower level comparing with the case in which the continuous projection portion or wall portion is provided from the lumber support region A2 to the buttock support region A3. - The cushion of the invention is not limited to the above embodiment, but the cushion of the invention can be realized in various modifications. Then, the
cushions 5 of other modifications will be described.FIG. 18 shows a modification in which thelumber pad 30 is changed. In the modification shown inFIG. 18 , thebase seat 31 of thelumber pad 30 is omitted, and only the pair ofside support portions 32 is provided in thelumber pad 30. That is, the pair ofside support portions 32 are not coupled to each other by thebase seat 31, but are separated from each other in the right and left direction. According to the configuration shown inFIG. 18 , when theseat 3 is folded in the right and left direction (width direction), the resistance of thecushion 5 is further decreased, which allows theseat 3 to be deformed more easily and smoothly. -
FIG. 19 shows a modification in which thebuttock pad 50 is changed. In the modification, thebuttock pad 50 includes afirst pad portion 50A and asecond pad portion 50B which can be separated from each other. Thebuttock support portion 53 is provided in thefirst pad portion 50A, and theknee support portion 54 is provided in thesecond pad portion 50B. Thefirst pad portion 50A and thesecond pad portion 50B are adapted to be independently detachable from theseat 3. According to thebuttock pad 50 having the configuration, the embodiment in which both thefirst pad portion 50A and thesecond pad portion 50B are used and the embodiment in which either thefirst pad portion 50A or thesecond pad portion 50B is used can be selectively used. For example, such a selective use that both thefirst pad portion 50A and thesecond pad portion 50B is used in a lower age in month, and only either thefirst pad portion 50A or thesecond pad portion 50B is used when the infant is grown is enabled. InFIG. 19 , although thelumber pad 30 has the same configuration as that ofFIG. 2 , thelumber pad 30 shown inFIG. 18 may be combined with thebuttock pad 50 ofFIG. 19 .FIG. 20 shows the example. - In the
above cushions 5, therespective pads seat 3 in various manners. For example, thepads seat cover 4 in an undetachable manner. As a fixing method for this case, various fixing methods such as hot pressing and sewing can be used. At least a part of thepads seat 3. When all thepads seat 3, only the necessary pad can be attached to theseat 3 while the unnecessary pads are detached from theseat 3 in thehead pad 10, thelumber pad 30, and thebuttock pad 50. For example, the embodiment in which only thelumber pad 30 and thebuttock pad 50 are used, the embodiment in which only thebuttock pad 50 is used, the embodiment in which only thehead pad 10 and thebuttock pad 50 are used, the embodiment in which only thehead pad 10 and thelumber pad 30 are used, and the like can be used separately as appropriate. Desirably, all thepads - The configuration for attaching the pad to the
seat 3 will be described below.FIGS. 21 and 22 show an example in which thecushion 5 shown inFIG. 18 is detachably attached to theseat cover 4. In this example, belt throughholes pads seat cover 4. Each of the belt throughholes 4 a to 4 c is a thin and long hole like a button hole. Fasteningbelts holes head pad 10, theside support portion 32 of thelumber pad 30, and thebuttock pad 50. InFIG. 21 , thefastening belt 40 of the leftside support portion 32 and theright fastening belt 60 of thebuttock pad 50 are omitted. - As shown in
FIG. 22 , aclamp 6A corresponding to the belt throughhole 4 a is provided in the backside of theseat cover 4. Aclamp 6B which can be connected to theclamp 6A of theseat cover 4 is provided at a front end of thefastening belt 20. Various kinds of connecting means such as a surface fastener and a hook can be used as theclamps FIG. 22 shows thefastening belt 20 and belt throughhole 4 a corresponding to thehead pad 10. Similarly theclamps fastening belts lumber pad 30 andbuttock pad 50 and the corresponding belt throughholes - According to the configuration, as shown in
FIG. 22 , thefastening belt 20 pierces through the belt throughhole 4 a from the surface side of theseat cover 4 to fix the front-end clamp 6B to theclamp 6A on the backside of theseat cover 4, which allows thehead pad 10 to be detachably attached to theseat cover 4. When theclamps head pad 10 can be changed in the longitudinal direction of theseat 3 by changing the position where theclamp 6B is fixed to theclamp 6A. When the plural belt throughholes 4 a are provided with predetermined intervals along the longitudinal direction of theseat 3, the position of thehead pad 10 can further be changed in the longitudinal direction of theseat 3 according to the selection of the belt throughhole 4 a through which thefastening belt 20 pierces. The position of thehead pad 10 is adjustably designed, which allows thehead pad 10 to be arranged at the proper position according to the infant physical body. - The
lumber pad 30 and thebuttock pad 50 can be attached to theseat cover 4 in the same manner. By forming the belt throughholes belts seat 3, and placing the plural clamps 6A corresponding to the belt throughholes seat 3, the positions of thelumber pad 30 andbuttock pad 50 may be adjustable in the longitudinal direction of theseat 3 respectively. When theclamps lumber pad 30 andbuttock pad 50 may be adjustable by providing thesingle clamp 6A longer than the belt width in the longitudinal direction of theseat 3. The positions of thelumber pad 30 andbuttock pad 50 may be adjustable by providing the plural belt throughholes seat 3. The integraltype lumber pad 30 having thebase seat 31 shown inFIG. 2 can be attached to theseat cover 4 by the configuration shown inFIGS. 21 and 22 . -
FIGS. 23 and 24 show an example in which thecushion 5 shown inFIG. 19 is detachably attached to theseat cover 4. The example is similar to the example shown inFIG. 21 in that thehead pad 10 is attached to theseat cover 4 by thefastening belt 20. However, plural hooks 70 (seeFIG. 24 ) are provided on both sides in the right and left direction of the backside of thehead pad 10 in a condition which the positions of thehooks 70 are shifted in the longitudinal direction of theseat 3, and thelumber pad 30 is coupled tohead pad 10 by engaging the hook 34 (seeFIG. 8 ) of thelumber pad 30 with thehook 70 in the upper stage or lower stage. The attachment position of thelumber pad 30 to thehead pad 10 can be adjusted in the longitudinal direction of theseat 3 by changing thehook 70 with which thehook 34 is engaged. The position of thehead pad 10 may be adjustable in the longitudinal direction of theseat 3 by the same configuration asFIG. 21 . In this case, thehook 70 is used as the coupling tool. However, the coupling tool is not limited to the hook, but the surface fastener and the like may be used. - Similarly to the example shown in
FIGS. 21 and 22 , thebuttock pad 50 is attached to theseat cover 4 by utilizing thefastening belt 60. However, in the example ofFIGS. 23 and 24 , thebuttock pad 50 is divided into thefirst pad portion 50A and thesecond pad portion 50B, and thefirst pad portion 50A and thesecond pad portion 50B are coupled to each other by engaging ahook 71 with a hook 72. Thehook 71 is provided in the backside of thefirst pad portion 50A, and the hook 72 is provided in the surface of thesecond pad portion 50B. Similarly to thehook 70 of thehead pad 10, the plural hooks 71 of thefirst pad portion 50A are provided while the positions of thehooks 71 are shifted in the longitudinal direction of theseat 3. Therefore, the position of theknee support portion 54 of thesecond pad portion 50B can be changed in the longitudinal direction of theseat 3 with respect to thebuttock support portion 53 of thefirst pad portion 50A. - In the example of
FIGS. 23 and 24 , thelumber pad 30 may be formed to be able to couple tohead pad 10 and to be able to attach theseat cover 4 by thefastening belt 40. Therefore, a usage pattern in which thehead pad 10 is taken out from theseat 3 and only thelumber pad 30 or thelumber pad 30 andbuttock pad 50 are attached to theseat 3 can also be selected. -
FIGS. 25 and 26 show another example in which thecushion 5 is detachably attached to theseat cover 4. In the example, thecushion 5 is attached to theseat 3 by utilizing theshoulder belt 7 and crotch belt 8 (seeFIG. 1 ) provided in theseat 3. Theshoulder belt 7 and thecrotch belt 8 are provided to constrain the infant to theseat 3, and are fixed to the base plate which is arranged as a core material inside theseat 3. In this example, thelumber pad 30 is detachably attached to theseat cover 4 by causing theshoulder belt 7 to pierce through the belt through hole 35 (seeFIG. 8 ). Similar to the example ofFIG. 23 , thehead pad 10 and thelumber pad 30 are coupled to each other. Thehead pad 10 may further be attached to theseat cover 4 by utilizing thefastening belt 20 like the examples shown inFIGS. 21 and 23 . Thebuttock pad 50 is detachably attached to theseat cover 4 by passing thecrotch belt 8 through a gap between thefirst pad portion 50A and thesecond pad portion 50B. The integraltype buttock pad 50 shown inFIG. 2 may be attached to theseat cover 4 by passing thecrotch belt 8 through the belt throughhole 55 provided in thebuttock pad 50. When the belt throughholes 55 are provided in thefirst pad portion 50A and thesecond pad portion 50B respectively, thecrotch belt 8 may be caused to pierce through each of the belt throughholes 55 when both thefirst pad portion 50A and thesecond pad portion 50B are used, and thecrotch belt 8 may be caused to pierce through one of the belt throughhole 55 to be used when either thefirst pad portion 50A or thesecond pad portion 50B is used. - In the above examples, the
pads cushion 5 are detachably attached to theseat cover 4. However, the cushion of the invention is not limited to the cushion attached to the seat cover. For example, as shown inFIGS. 27 and 28 , thepads base plate 9 which is arranged as the core material inside theseat 3. When thebase plate 9 is configured by combining theback plate 9A and theseat plate 9B so that they are foldable along the bending line L1, thehead pad 10 and thelumber pad 30 may be attached to theback plate 9A, and thebuttock pad 50 may be attached to theseat plate 9B. When thepads base plate 9, it is not necessary to attach and detach thecushion 5 when theseat cover 4 is taken out from thebase plate 9. Particularly, in washing theseat cover 4, there is an advantage that it is not necessary to remove thecushion 5 from theseat cover 4. - The
pads base plate 9 in an undetachable manner, or thepads base plate 9. Various coupling means such as the surface fastener, the belt, and the hook or the like may be used as means for detachably attaching the pad to thebase plate 9. As shown by arrows inFIGS. 27 and 28 , thepads pads seat 3. - The invention is not limited to the above configurations, but various changes and modifications could be realized. For example, the
head pad 10 may have the configuration in which theneck support portion 13 and thetemporal support portion 14 are separated from each other. When the head pad is not required from the viewpoint of usage of the baby carriage, for example, when the cushion of the invention is applied to the baby carriage focusing on only the infant having the relatively higher age in month after the baby head is held up, the head pad is omitted and the cushion may be formed only by the lumber pad and the buttock pad. The configuration in which the pad is attached to the seat is not limited to the above examples, but various modifications can be applied as appropriate. The pad can be attached to the seat cover or the base plate using appropriate means such as the hook, a string, a buckle, and a button. When the interior material is provided in the pad, the interior material may be made of a porous material to impart the air flow to the pad, or the air flow may be imparted to the pad by making many through holes in the interior material.
