[0058] The present application will be described in detail with reference to the drawings. In addition, the same reference numerals are used throughout the drawings and the description to refer to the same or like parts.
[0059] (Outline of child seat)
[0060] Reference Figure 1 、 Figure 2A 、 Figure 2B An outline of a child seat 1 as a child care appliance for a young child according to the present embodiment will be described. In the description of the child seat 1, the front-rear direction corresponds to the front-rear direction of the child seat 1, the left-right direction (width direction) corresponds to the left-right direction as viewed from the front of the child seat 1, and the up-down direction corresponds to the up-down direction of the child seat 1.
[0061] The child seat 1 has a base body 2 and a seat 3. The child seat 1 has substantially the same structure as a general child seat, and is a device configured to be placed on a seat of an automobile to allow a child such as an infant or a young child to ride safely. The child seat 1 has a base body 2 and a seat 3.
[0062] The base body 2 is placed on a seat cushion of an automobile and supports the seat 3 from below. Although not shown, a leg support extending toward a floor surface of the automobile is provided at a front end of the base body 2, and an ISOFIX (International Organization for Standardization Fix) that is connected to an anchor portion of the seat cushion of the automobile can be provided at a rear end of the base body 2. The seat 3 is rotatably supported on the base body 2.
[0063] The seat 3 is mounted on an upper side of the base body 2 and is rotatably supported on the base body 2. In Figure 1 , a state in which a soft cloth member, for example, a cushioning member, is mounted on the seat 3 is shown.
[0064] The seat 3 includes a seat surface portion 4 and a backrest portion 5. A child sits on the seat 3. Therefore, the seat surface portion 4 supports the buttocks of the child, and the backrest portion 5 stands from the rear of the seat surface portion 4 to support the back of the child. A detachable cushioning structure 20 is mounted at a corner portion where the seat surface portion 4 and the backrest portion 5 intersect. The cushioning structure 20 includes a cushioning body 22 and a housing 21 that surrounds a surface of the cushioning body 22 other than an upper surface.
[0065] The backrest 5 includes a backrest 50 and a sliding member 6 that overlaps the front surface of the backrest 50 and can slide vertically. The sliding member 6 overlaps the front surface of the backrest 5 and can slide vertically. The sliding member 6 functions as a headrest. Therefore, the sliding member 6 includes a vertical wall portion 61 that protects the back of a child's head and a pair of side wall portions 66 that protect the sides of a child's head. The side wall portions 66 are mounted at both ends of the vertical wall portion 61 in the left and right directions and protrude forward. Furthermore, a soft fabric component, such as a cushioning material, can be installed on the sliding member 6, just like on the seat 3. The sliding member 6 will be described below.
[0066] like Figure 1 As shown, shoulder straps 10 are provided on the backrest 5 to restrain the shoulders of a child sitting in the seat 3. Furthermore, a crotch strap 11 extends between the legs (thighs) of the child sitting in the seat 3, and a pair of waist belts 12 restrain the child's waist, are provided on the seat surface 4. These shoulder straps 10, crotch straps 11, and waist belts 12 are connected near the child's abdomen by buckles 14 located at the front ends of the crotch straps 11. These shoulder straps 10, crotch straps 11, and waist belts 12 constitute a so-called five-point harness.
[0067] Shoulder straps 10, for example, long, strip-shaped cords. Specifically, such as... Figure 2A and Figure 2B As shown, the shoulder strap 10 is configured in a loop shape and passes through the shoulder strap through hole 62 in the sliding member 6 and the back 50, and extends into the seat surface 4 through the back side of the back 5.
[0068] Like the shoulder strap 10, the waist belt 12 is, for example, a long, strip-shaped cord. The shoulder strap 10 and the waist belt 12 may not be formed from separate straps, or they may be set as a continuous single strap.
[0069] The crotch strap 11 is typically a strap-shaped rope, similar to the shoulder strap 10, but it can also be a plate-shaped component or a tubular component, and is not limited to the type of belt.
[0070] Previously, when seating a child in a car seat, the harness located underneath the child had to be pulled outwards or retracted to the side of the seat before the child could sit down, especially since the shoulder straps could be obstructive. In contrast, as... Figure 2A , Figure 2B As shown, the child seat 1 of this embodiment can be positioned in a "restraint position" where the child's body is restrained by the shoulder straps 10. Figure 2A ")" and "open position" which forms an open space by standing upright from the backrest 5. Figure 2B Therefore, when a child sits in the child seat 1, an open space is created in the seat 3, so the shoulder strap 10 will not cause obstruction.
[0071] The shoulder belt holding unit 7 is provided to change the position of the shoulder belt 10 to a restraining position and an open position. The shoulder belt holding unit 7 of the present embodiment is provided to the slide member 6. Before explaining the shoulder belt holding unit 7, the configuration of the slide member 6 will be explained.
[0072] (Regarding the slide member)
[0073] Reference will now be made to Figure 3 the slide member 6. Figure 3 is an exploded perspective view of the slide member 6.
[0074] As described above, the slide member 6 is a member that is overlaid on the front surface of the back 50 and is slidable in the up-and-down direction. The slide member 6 is provided with a shoulder belt through-hole 62 through which the shoulder belt 10 is passed, and the slide member 6 is contactable with the slide member 6 downwardly in accordance with the growth of the child.
[0075] As shown in Figure 3 , the slide member 6 includes a front portion 60 located on the back side of the child, a rear portion 64 located on the back side, and a plate 80 located between the front portion 60 and the rear portion 64. In other words, the slide member 6 is divided into the front portion 60 and the rear portion 64, and the plate 80 is sandwiched between the front portion 60 and the rear portion 64.
[0076] The front portion 60 includes a front vertical wall portion 61a, a pair of front hole portions 62a provided below the front vertical wall portion 61a, and a pair of opening portions 63 located above the pair of front hole portions 62a. The shoulder belt 10 is passed through the pair of front hole portions 62a. The shoulder belt holding member 70 of the shoulder belt holding unit 7, which will be described later, is passed through the pair of opening portions 63.
[0077] The rear portion 64 includes a rear vertical wall portion 61b, a pair of side wall portions 66 protruding forward from the side ends of the rear vertical wall portion 61b, and a pair of leg portions 67 protruding downward from the side ends of the rear vertical wall portion 61b. The rear vertical wall portion 61b is superimposed with the front vertical wall portion 61a to form a vertical wall portion 61. A pair of rear hole portions 62b is provided below the rear vertical wall portion 61b. The pair of rear hole portions 62b is provided at positions corresponding to the pair of front hole portions 62a of the front portion 60. In this way, the front hole portions 62a and the rear hole portions 62b are combined front and rear, and a pair of shoulder belt through-holes 62 is formed to allow the shoulder belt 10 to be passed therethrough. Although not shown, a cover member made of a thin material is provided to the pair of leg portions 67 to cover the front surface of the back 50.
[0078] The plate 80, sandwiched between the front portion 60 and the rear portion 64, forms part of the shoulder strap holding unit 7, and the plate 80 supports the shoulder strap holding member 70 so that it can rotate relative to the sliding member 6. The shoulder strap holding member 70 is used to change the position of the shoulder strap 10 to an open position and a restrained position. The shoulder strap holding unit 7 is described in detail below.
[0079] (Regarding the shoulder strap retainer)
[0080] Next, further reference Figures 4 to 8 The description refers to the shoulder strap holding unit 7 installed in the sliding member 6. The shoulder strap holding unit 7 is a member used to change the position of the shoulder strap 10 to an open position and a restrained position. Figure 4 Part (A) is an exploded perspective view showing the shoulder strap holding unit 7 located on the left side in the width direction being removed from the sliding member 6. Figure 4 Part (B) is a diagram illustrating the guide area 90 of the shoulder strap retaining unit 7. Additionally, Figure 4 The arrow A following part (A) indicates the outer width direction. Figure 5 Part (A) and Figure 6 Show the restraint position of shoulder strap 10. Figure 5 Part (B) and Figure 7 Show the intermediate position between the open and restrained positions. Figure 5 Part (C) and Figure 8 Showing the open position of shoulder strap 10. Figures 4 to 8 The illustration of shoulder strap 10 is omitted.
[0081] like Figure 4 As shown in part (A), the shoulder strap holding unit 7 includes: a shoulder strap holding member 70 for holding the shoulder strap 10; a plate 80 disposed on the sliding member 6; and a movable part 72 that allows the shoulder strap holding member 70 to move relative to the plate 80.
[0082] The shoulder strap retaining member 70 is disposed along the shoulder strap 10 and moves with the shoulder strap 10, and is rotatably supported on the sliding member 6. Specifically, the shoulder strap retaining member 70 is disposed above the shoulder strap 10 and allows the shoulder strap 10 to move upward, downward, and left and right.
[0083] The shoulder strap retaining member 70 is elastically deformable and is formed of a flexible synthetic resin. Therefore, even when the shoulder strap 10 is connected to the buckle 14 in a restrained position, the shoulder strap retaining member 70 will conform to the child's body, thus preventing discomfort. The shoulder strap retaining member 70 is a long, rod-shaped member including a front end and a rear end. The rear end of the shoulder strap retaining member 70 is fixed to the aforementioned movable part 72 and can rotate relative to the backrest 5. Alternatively, the shoulder strap retaining member 70 and the movable part 72 can be integrally formed.
[0084] As shown in Figure 2A , Figure 2B , the shoulder strap 10 and the shoulder strap holding member 70 are covered by the covering member 13. The covering member 13 covers the shoulder strap 10 and the shoulder strap holding member 70 from the outside, and transmits the action of the shoulder strap holding member 70 to the shoulder strap 10. The covering member 13 of the present embodiment is a cloth material sewn in a cylindrical shape, but may, for example, be a cloth material folded in two. The covering member 13 functions as a pad for the shoulder strap 10, and the covering member 13 can also be a member that softens the sense of touch to the child's shoulder. The covering member 13 preferably extends from the position of the shoulder strap through-hole 62 to the position of the front end portion of the shoulder strap holding member 70. The shoulder strap holding member 70 and the shoulder strap 10 can be directly connected by being sewn or joined, in addition to being abutted via the covering member 30.
[0085] As shown in Figure 4 (A), the plate 80 includes a front plate 81 and a rear plate 85. As shown in Figure 6 (B) and Figure 6 (C), the front plate 81 is positioned on the front portion 60 side of the slide member 6, and the rear plate 85 is positioned on the rear portion 64 side of the slide member 6. The rear plate 85 is fixed to the back of the front plate 81 at a position of the lower half.
[0086] As shown in Figure 4 (A), the front plate 81 includes a front plate body 82, a front semicircular cover portion 83 provided below the front plate body 82 and protruding forward, and a hole portion 84 provided in the front semicircular cover portion 83. Further, the rear plate 85 includes a rear plate body 86, a rear semicircular cover portion 87 provided in the substantially central portion of the rear plate body 86 and protruding rearward, and a guide region 90 provided in the rear semicircular cover portion 87. The guide region 90 will be described later in the description of the movable portion 72.
[0087] The movable portion 72 provided between the front plate 81 and the rear plate 85 includes a fixed portion 73 that holds the shoulder strap holding member 70, and a ball shaft portion 74 provided at the front end of the fixed portion 73. As shown in Figure 5 (B), the movable portion 72 is positioned directly above the shoulder strap through-hole 62, and can raise and lower the shoulder strap 10 from the root portion.
[0088] Returning to Figure 4The fixed portion 73 is a cylindrical body, and a recessed portion 73a is provided at the front end on the side opposite to the spherical shaft portion 74. This recessed portion 73a holds the rear end portion of the shoulder harness holding member 70. A protruding portion (abutting portion) 75 is provided on the spherical shaft portion 74 so as to protrude outward. The abutting portion 75 protrudes in a direction opposite to the direction in which the fixed portion 73 (shoulder harness holding member 70) extends. The spherical shaft portion 74 is rotatably held in the front semicircular cover portion 83 of the front plate 81 and the rear semicircular cover portion 87 of the rear plate 85. By this, the shoulder harness holding member 70 is held so as to be rotatable with respect to the backrest portion 5. Also, the abutting portion 75 provided on the spherical shaft portion 74 is disposed in the guide region 90 provided in the rear plate 85, and moves in the guide region 90.
[0089] In addition, the abutting portion 75 of the present embodiment is provided on the movable portion 72 fixed to the rear end portion of the shoulder harness holding member 70, but can be provided on the proximal end of the shoulder harness holding member 70. Here, the proximal end is a portion provided near the rotation point of the shoulder harness holding member 70 in the region where the backrest portion 5 and the shoulder harness holding member 70 cross, and is not limited to the rear end portion as long as it is near the rotation point.
[0090] Figure 4 The (B) portion shows the guide region 90 provided in the rear plate 85. The guide region 90 of the present embodiment is a through hole, but can be, for example, a groove or a rail, and is a member for guiding the movement of the abutting portion 75. The guide region 90 is, for example, V-shaped when viewed from the front, and has a movement prohibition region 91 and a movement allowance region 93 which branch.
[0091] The movement prohibition region 91 is a region in which the front end portion of the shoulder harness holding member 70 is prohibited from moving downward. That is, the movement prohibition region 91 is a region in which the shoulder harness holding member 70 is positioned in the open position.
[0092] The movement allowance region 93 is a region positioned offset in the width direction from the movement prohibition region 91, and allows the front end portion of the shoulder harness holding member 70 to move downward. That is, the movement allowance region 93 is a region in which the shoulder harness holding member 70 is positioned in the restraint position. The movement prohibition region 91 is preferably positioned further outward in the width direction than the movement allowance region 93. By this, during the period in which the abutting portion 75 of the movable portion 72 is positioned in the movement prohibition region 91, the shoulder harness holding member 70 is positioned outward in the width direction, and the front end of the shoulder harness holding member 70 is directed outward, so the shoulder harness 10 can be more effectively set in the open position.
[0093] A protrusion 95 is provided between the movement-prohibited region 91 and the movement-allowed region 93, which prevents the abutment portion 75 from moving in the width direction. In this embodiment, the protrusion 95 is a downward protrusion, but it can also be, for example, a protrusion facing left and right or a protrusion facing forward and backward. By providing the protrusion 95, the operator needs to cross the protrusion 95 to switch between the movement-prohibited region 91 and the movement-allowed region 93, thus ensuring good operability.
[0094] like Figure 4 As shown in section (B), a contact blocking part 92 is provided at the uppermost end of the movement-prohibited area 91. This contact blocking part 92 is used for contact with the abutment part 75 of the movable part 72. In this embodiment, the contact blocking part 92 is a step, but it can be any shape that blocks the movement of the abutment part 75. Figure 5 Part (C) and Figure 8 The movable part 72's abutting part 75 is in contact with the contact blocking part 92. By allowing the movable part 72's abutting part 75 to abut against the contact blocking part 92, the front end of the shoulder strap retaining member 70 in the second position can be prevented from moving downwards. That is, the shoulder strap retaining member 70 can be set to the "open position".
[0095] The height position of the contact blocking part 92 is preferably set to a position where the shoulder strap holding member 70 is upright from the backrest 5. Specifically, it is preferably set to a position where the angle between the backrest 5 and the shoulder strap holding member 70 is 50° or more, and more preferably 60° or more.
[0096] like Figure 4 As shown in section (B), a contact portion 94 is provided at the uppermost end of the movement-allowed region 93. This contact portion 94 is used to abut against the contact portion 75 of the movable portion 72. In this embodiment, the contact portion 94 and the contact blocking portion 92 are both stepped, but it only needs to be shaped to block the movement of the contact portion 75. Figure 5 Part (A) and Figure 6 The movable part 72 is shown in the state where the abutting part 75 abuts against the abutted part 94. By allowing the abutting part 75 of the movable part 72 to abut against the abutted part 94, the shoulder strap 10 can be held in a position that restrains the child's body. That is, the shoulder strap holding member 70 can be set to a "restraint position".
[0097] The height of the abutment portion 94 is preferably set such that the shoulder strap retaining member 70 is upright at a position corresponding to the thickness of the child sitting in the seat 3. Specifically, it is preferably set such that the angle between the backrest 5 and the shoulder strap retaining member 70 is 45° or less, more preferably 40° or less. In addition, although the abutment portion 94 is provided in this embodiment to keep the shoulder strap 10 in a restrained position, it may not be provided.
[0098] In this embodiment, the combination of the abutting portion 75 of the movable part 72 and the contact blocking portion 92 of the guide area 90 is called a "switching device". The switching device is a device that switches the shoulder strap holding member 70 between a first position corresponding to the restrained position and a second position corresponding to the open position. In the following description, from the point of view of easy understanding, the first position of the shoulder strap holding member 70 will be described as the restrained position and the second position of the shoulder strap holding member 70 will be described as the open position.
[0099] (Regarding the action)
[0100] The following is for reference. Figures 5 to 8 This explains the operation of the shoulder strap retaining unit 7.
[0101] First, the method for switching the shoulder strap 10 from the restrained position to the open position will be explained. This action is performed before the child sits in and gets out of the child seat 1 to ensure that the shoulder strap 10 does not obstruct movement. Simply put, it is done by holding the child in the restrained position with your hand. Figure 5 The pair of shoulder straps 10 in part (A) (shoulder strap retaining member 70 of shoulder strap retaining unit 7, in Figures 5 to 8 (The illustration of shoulder strap 10 is omitted) and move it slightly upwards (midpoint position: Figure 5 (Part B), for example Figure 5 As shown in section (C), each of the two shoulder straps 10 is moved outward in the wide direction (left-right direction) to be in an open position.
[0102] Specifically, refer to Figure 5 Part (A) and Figure 6 The shoulder strap 10 is held in the restrained position by hand. When the shoulder strap 10 is in the restrained position, the front end of the shoulder strap retaining member 70 faces downward. Furthermore, as... Figure 6 Part (B) Figure 6 As shown in part (C), the contact portion 75 is located in the movement allowable area 93 and abuts against the contacted portion 94.
[0103] Next, refer to Figure 5 Part (B) and Figure 7 This causes the shoulder strap 10 to move upwards, and the abutment portion 75 of the shoulder strap retaining member 70 to move downwards along the movement allowable region 93 of the guide region 90. For example... Figure 7 Part (B) Figure 7 As shown in section (C), when the shoulder strap 10 is in the middle position, the abutment 75 is located below the protrusion 95.
[0104] Next, refer to Figure 5 Part (C) and Figure 8The pair of shoulder belts 10 are each moved outward in the width direction. The abutting portion 75 is guided to the movement prohibition area 91 by the convex portion 95 of the guide area 90. The shoulder belt holding member 70 is moved downward by its own weight, so the abutting portion 75 provided at the rear end portion of the shoulder belt holding member 70 is automatically moved upward. When the shoulder belt 10 is in the open position, as shown in FIG. 6, the abutting portion 75 of the shoulder belt holding member 70 abuts against the contact blocking portion 92, so the front end portion of the shoulder belt holding member 70 is prohibited from moving downward. By this, the shoulder belt 10 is held in the open position. Figure 8
[0105] To switch the shoulder belt 10 from the open position to the restraint position, the reverse order of the above-described method is used.
[0106] According to the above, the child seat 1 of the present embodiment is provided with the shoulder belt holding member 70 and the switching device, so the shoulder belt 10 can be held in the open position, and the shoulder belt 10 does not interfere, so the child can sit on and get off the child seat 1. Furthermore, the shoulder belt 10 can be moved from the restraint position to the open position by simply holding the shoulder belt 10 with the hands and moving it upward, downward, leftward, and rightward, so the operability is good. In addition, the shoulder belt holding unit 7 is a simple structure, so the number of parts can be reduced, so the cost can be suppressed.
[0107] Furthermore, the front end portion of the shoulder belt holding member 70 is moved downward by its own weight, and the rear end portion is moved upward so the abutting portion 75 engages with the contact blocking portion 92, by simply holding the shoulder belt 10 with the hands and moving it outward in the width direction, so the shoulder belt 10 can be held in the open position without a particularly difficult operation.
[0108] In the conventional child seat, the shoulder belt is constantly applied with tension in the open direction, so when the child is seated on the child seat, the child cannot be surely restrained in the child seat by the shoulder belt. However, the child seat 1 of the present embodiment does not apply tension to the shoulder belt 10, so the child can be surely restrained by the shoulder belt 10.
[0109] In addition, in the above-described embodiment, a child care appliance for young children was described as the child seat, but this is not limited thereto, and for example, can be a child care appliance with a seat such as a stroller, a baby carriage, a baby cradle, a child care chair, and the like.
[0110] Furthermore, in the present embodiment, although the shoulder belt 10 is configured so that its position is held in the open position and in the restraint position, it can also be configured so that the shoulder belt 10 is held only in the open position.
[0111] Further, although the switching device is provided as the sliding member 6 provided to the backrest portion 5, it can also be provided to a region where the shoulder belt holding member 70 intersects with the backrest portion 5, that is, it can also be provided to the front or the rear of the backrest portion 5.
[0112] Further, although the shoulder belt holding member 70 of the present embodiment is a member that moves the shoulder belt 10 upward, downward, and in the left-right direction, it can be a member that moves to set the shoulder belt 10 to the restrained position and the open position. For example, the shoulder belt holding member 70 can be a member that moves only in the up-down direction, or it can be a member that moves only in the left-right direction, and the shoulder belt holding member 70 can also be a member that faces toward the inner side in the width direction in the restrained position and faces toward the outer side in the width direction in the open position.
[0113] The embodiments of the present application have been described above with reference to the accompanying drawings, but the present application is not limited to the illustrated embodiments. Various modifications or alterations can be made to the illustrated embodiments within the same scope or equivalent scope of the present application.
