Description

child seat

The present invention relates to a child seat, and is suitable for use, for example, when attached to a car.

Conventionally, child seats have been widely used by attaching them to the seats of vehicles such as automobiles, for example, when infants are placed in them. When the infant is relatively small and the seat belt of the vehicle should not be used, the child seat is fixed to the vehicle and the infant is restrained by a seat belt (also called a harness) provided on the child seat. It has become.

Regarding child seats, a standard called ISOFIX has been established as a method for fixing them to the vehicle. In this ISOFIX, an engaging metal fitting protruding rearward from the rear lower side of the child seat is engaged with a metal fitting incorporated in the vehicle seat, and the tip of a string-like top tether provided near the upper end of the back is attached. is engaged with a predetermined metal fitting on the vehicle side.

On the other hand, child seats can safely use the vehicle's seat belts if the infant has a relatively large physique. In this case, the child seat does not have to be fixed to the vehicle. Therefore, as a child seat, a child seat has been proposed in which the fittings of the ISOFIX are configured to be displaceable in the front-rear direction, and are displaced rearward to protrude when in use, while being displaced forward and retracted when not in use ( For example, see Patent Document 1).

The seat belt group 4 (FIG. 1) is composed of a combination of a plurality of belts such as crotch belts 51, shoulder belts 52 and tightening belts 53, and parts such as buckles 54 and tongues 55. As shown in FIG. Of these belts, the crotch belt 51, the shoulder belt 52 and the tightening belt 53 are mainly composed of flat belts. By weaving predetermined fibers in a predetermined manner, the belt has a relatively long width, a relatively short thickness, and a sufficient length. It has tensile strength.

The crotch belt 51 has its lower end attached to the belt attachment portion 25 (FIGS. 2 and 3) provided on the seat portion 11, and its upper end to which the buckle 54 is attached. The shoulder belts 52 are provided so as to connect the vicinity of the upper side of the shoulder and the outer side of the waist on each of the left and right sides of the infant. A tongue 55 for engagement with the buckle 54 is inserted through each shoulder belt 52 .

The shoulder belts 52 are pulled into the back body portion 41 through the belt insertion holes 48 (FIG. 4) of the back displacement portion 42 located near the shoulders of the infant. Further, the shoulder belts 52 are connected to one tightening belt 53 inside the back body portion 41 . As an example, the tightening belt 53 can have a width (that is, length in the lateral direction) of approximately 25 [mm].

The tightening belt 53 travels downward inside the back base portion 41 and is pulled out from the back side belt insertion hole 47 ( FIG. 4 ) provided in the central lower surface 46 of the back base portion 41 . The tightening belt 53 enters the interior of the seat portion 11 through a seat-side belt insertion hole 28 (FIG. 3) provided in the rear center protrusion 27 of the seat portion 11 and advances forward to reach the front end of the seat portion 11.

Furthermore, the tightening belt 53 is pulled forward. As a result, the seat belt group 4 can restrain the infant's shoulders to waist on the back portion 12 of the child seat main body 2, and the infant can be maintained in a seated state.

[4. Configuration of top tether]
FIG. 5 is a schematic perspective view showing the top tether 5. FIG. The top tether 5 is roughly composed of a tether belt 71 , an adjusting portion 72 , a connecting belt 73 and a tether fitting 74 .

The tether belt 71, like the shoulder belt 52 (FIG. 1) of the seat belt group 4, has a relatively long width, a relatively short thickness, and a sufficient length. and has sufficient tensile strength. One end of the tether belt 71 is fixed to the tether attachment portion 43 ( FIG. 4 ) of the back portion 12 . Hereinafter, with respect to the longitudinal direction of the tether belt 71, the side fixed to the tether attachment portion 43 is called the fixed side, and the opposite side is called the leading end side. Further, the tether belt 71 can have a belt width of approximately 40 mm, for example.

The adjustment part 72 is mainly composed of a main body part 81 shaped like an overturned columnar body having a triangular cross section (that is, a triangular prism). As an example, the body portion 81 can have a length (hereinafter also referred to as the width of the body portion 81) in the direction along the central axis (not shown) of the triangular prism of approximately 65 [mm]. In addition, the length of the longest side of the main body portion 81 is about 80 [mm] in a triangle, and the length to the vertex of which the longest side is the opposite side (hereinafter also referred to as the height of the main body portion 81). can be about 28 [mm].

The body portion 81 is provided with a tether belt insertion hole 82 for inserting the tether belt 71, a connection belt insertion hole 83 for inserting the connection belt 73, and the like. Both the tether belt insertion hole 82 and the connection belt 73 are formed in an elongated slit shape along the central axis (not shown) of the triangular prism of the main body 81 .

In addition, the adjusting portion 72 includes a pressing component (not shown) that is pressed against the tether belt 71, a biasing component (not shown) that biases the pressing component against the tether belt 71, and the like. Furthermore, an operation unit 84 is provided for receiving operations by a parent or the like.

With the tether belt 71 inserted through the tether belt insertion hole 82 , the adjustment part 72 presses the pressing part against the tether belt 71 with the biasing part. This fixes the position of the adjusting portion 72 with respect to the tether belt 71 .

In addition, when the operation portion 84 is operated (specifically, pushed) by a parent or the like, the adjustment portion 72 temporarily separates the pressing member from the tether belt 71 and moves the position relative to the tether belt 71 to the fixed side or the distal end side. It is possible to change to After that, when the operation of the operation part 84 is released, the adjustment part 72 presses the pressing part against the tether belt 71 by the action of the biasing part, and holds the current position with respect to the tether belt 71 .

The connection belt 73 is composed of a belt-shaped member similar to the tether belt 71, and has flexibility and sufficient tensile strength. One end of the connection belt 73 is inserted through the connection belt insertion hole 83 of the adjustment portion 72 , and the other end is inserted through the tether fitting 74 . As an example, the connection belt 73 can set the interval between the adjusting portion 72 and the tether fitting 74 to about 40 [mm].

The tether metal fitting 74 has a configuration in which a spring portion 92 is attached to a body portion 91 . The body portion 91 is formed into an elongated shape as a whole by cutting and bending a steel plate having a sufficient thickness. The body portion 91 has a relatively wide base side, which is one of the longitudinal directions, and has an insertion hole 91H for inserting the connection belt 73 in the base side.

The tip side opposite to the root side of the body portion 91 is formed relatively thin, and the tip portion is bent in an arc shape toward the root side. In other words, when viewed from the side, the tip side of the body portion 91 has a shape that looks like a capital letter "J" or its reverse. The tip portion of the body portion 81 is hereinafter referred to as the tip portion 93 .

As an example, the tether fitting 74 can have a longitudinal length of approximately 80 [mm] and a lateral length of approximately 25 [mm] in the body portion 91. . Furthermore, the tether fitting 74 can have a diameter of approximately 20 [mm] when the distal end portion 93 is regarded as an arc.

The spring portion 92 is an elongated metal plate that is sufficiently thinner than the main body portion 91, is gently curved, and has elasticity. One end of the spring portion 92 is fixed to the root side of the body portion 91 and the other end is in contact with the inside of the tip portion 93 .

This tether metal fitting 74 deforms the spring portion 92 so as to temporarily approach the main body portion 91, and hooks the tip portion 93 on a predetermined fixing metal fitting or the like. The state of being engaged with the fixture can be maintained.

By the way, the length of each part in the child seat 1 can also be expressed as a relative length based on the belt width of the tether belt 71 in the top tether 5 (approximately 40 [mm] as an example). Hereinafter, the belt width of the tether belt 71 will be referred to as a reference belt width WB.

That is, the length of the main body portion 81 of the adjustment portion 72 in the direction along the central axis (not shown) of the triangular prism is about 1.65 times the reference belt width WB, and the length of the longest side is about 1.65 times. is approximately double. In addition, the distance between the adjusting portion 72 and the tether metal fitting 74 in the connecting belt 73 is approximately equal to the reference belt width WB. Furthermore, the longitudinal length of the tether fitting 74 is about twice the reference belt width WB.

The storage recess 26 (FIGS. 2 and 3) of the seat portion 11 described above has a length in the front-rear direction of about 3.5 times and a length in the left-right direction of about 2 times the reference belt width WB. 0.75 times, and the depth (vertical length) in the vicinity of the bearing surface top portion 21ST is about 1.25 times.

That is, the lengths in the front-rear direction and the left-right direction of the storage recess 26 are sufficiently larger (longer) than the length of the longest side of the body portion 81 of the adjusting portion 72 and the length of the tether fitting 74 in the longitudinal direction. ing.

Therefore, the child seat 1 can secure a space for the tightening belt 53 to pass through while securing a sufficient depth. In addition, since the child seat 1 is a space in which the storage recess 26 is recessed downward with respect to the seat surface 21S, it is possible to store the top tether front end portion 5F and the like easily by the action of gravity without providing a lid or the like. can be maintained at

Furthermore, in the child seat main body 2, a through hole 13 is formed at the boundary between the combined seat portion 11 and back portion 12 (Fig. 2, etc.). Therefore, in the child seat 1, a hole for pulling out the top tether 5 from the rear side to the front side of the back portion 12 can be formed only by forming the through hole 13 as a relatively large gap between the seat portion 11 and the back portion 12. can be done. As a result, in the child seat 1, compared to the case where a hole for inserting the top tether 5 is separately provided in the back portion 12 or the seat portion 11, the strength can be increased and the degree of freedom in design can be increased.

In addition to this, in the back portion 12, the length of the back belt insertion hole 47 (FIG. 4) in the left-right direction (approximately 80 [mm] as an example) is larger than the width of the tightening belt 53 (25 [mm] as an example). Configured large enough (long). Therefore, in the child seat 1, when inserting the tip side of the top tether 5 into the through-hole 13, the tightening belt 53 can be easily bent in the left-right direction, and the adjusting portion 72 and the like can be easily inserted ( Figure 8).

According to the above configuration, the child seat 1 according to the present embodiment is provided with the storage recess 26 in the seat portion 11 of the child seat body 2, and the through hole 13 is provided at the boundary portion between the seat portion 11 and the back portion 12 when the seat portion 11 and the back portion 12 are joined. to form The child seat main body 2 inserts the top tether 5 from the rear side to the front side of the through-hole 13 and stores the top tether front part 5F in the storage recess 26 in the non-fixed use state in which the top tether 5 is not used. Therefore, when the child seat 1 is used in an unfixed state, the top tether front part 5F can be accommodated in the seat part 11, and the root side part of the tether belt 71 can be maintained in a state of being substantially closely attached to the child seat body 2.例文帳に追加
