(Overview of child seats)
A child seat 1 according to an embodiment of the present invention will be described with reference to FIG. In the description of the child seat 1 , the front-rear direction corresponds to the front-rear direction of a child seated in the child seat 1 . The width direction corresponds to the lateral direction of a child seated in the child seat 1 or the lateral direction of the belt. The inner side corresponds to the side facing the child seated in the child seat 1 . The outside corresponds to the side opposite the child seated in the child seat 1 .

A child seat 1 according to the present embodiment is a child seat device that is placed on a seat of an automobile and allows children such as infants and toddlers to safely ride in the vehicle. The child seat 1 has a base body 10 and a seat body 11 . The base body 10 is placed on the seat of a passenger car and supports the seat body 11 from below. The seat body 11 is attached to the upper side of the base body 10 and supported rotatably with respect to the base body 10 .

A child sits on the seat body 11 . Therefore, the seat body 11 is also called a child's seat, and has a seat portion 2 that supports the buttocks of the child, and a backrest portion 3 that rises from the rear of the seat portion 2 and supports the back of the child. A covering member 20 for the seat portion 2 is detachably attached to the frame of the seat portion 2 . A covering member 30 for the backrest portion 3 is detachably attached to the frame of the backrest portion 3 . These covering members 20 and 30 are made of a soft cloth member, such as a cushion material or a mesh material.

The backrest portion 3 is provided with a slide member 4 that overlaps the backrest portion 3 and is slidable in the vertical direction. The slide member 4 is a headrest that supports the child's head, and can be fixed at an arbitrary height position by a lock mechanism (not shown). In addition, as shown in FIG. 1, the front surface of the slide member 4 may be covered with a cover member. The backrest portion 3 may be provided so as to be reclinable by being inclined with respect to the seat surface portion 2, or the inclination angle with respect to the seat surface portion 2 may be fixed. In this case, the seat body 11 may be slidably provided with respect to the base body 10 .

A child seat 1 is provided with a plurality of belts for restraining a child's body. The belts provided on the backrest portion 3 include a pair of shoulder belts 12 for restraining both shoulders of the child. The shoulder belt 12 is arranged so as to pass through the slide member 4 and the backrest portion 3 . One end of the shoulder belt 12 is connected to a belt length adjusting mechanism (not shown) on the rear side of the backrest portion 3 . A middle region and the other end of the shoulder belt 12 are arranged on the front side of the backrest portion 3 .

Belts provided on the seat surface 2 include a crotch belt 13 extending between the thighs of the child seated on the seat body 11, and a crotch belt 13 extending laterally across the seat body 11 to restrain the waist of the child. A waist belt 14 is included. One end of the crotch belt 13 is fixed to the central portion of the seat portion 2 in the width direction. The waist belts 14 are arranged on the left and right, and one end of each waist belt 14 is fixed to both sides of the seat portion 2 in the width direction.

The other ends of these belts 12 , 13 , 14 are connected to each other near the abdomen of the child by a connector 15 provided at the tip of the crotch belt 13 . The connector 15 is preferably a detachable buckle. In this embodiment, the shoulder belt 12 and the waist belt 14 are formed of the same long belt, and a tongue 19 connected to the connector 15 is provided in the middle of the belt.

The relationship between the backrest portion 3, the slide member 4, and the shoulder belts 12 will be described. FIG. 2 is a front view of the child seat 1 according to this embodiment, showing a state in which the covering member 30 of the backrest portion 3 is removed. Furthermore, FIG. 2 shows a state in which the pair of shoulder belts 12 are held by the pair of shoulder belt holding portions 5. As shown in FIG. FIG. 2(a) is a front view showing a state in which the slide member 4 is fixed at the lowest height, and FIG. 2(b) is a state in which the slide member 4 is fixed at the highest height. It is a front view showing. For ease of understanding, the slide member 4 is shown with light ink.

The slide member 4 is slidably attached to the frame of the backrest portion 3 . The slide member 4 is slidable to any height position and fixed at any height position by a lock mechanism (not shown). The slide member 4 can slide up and down according to the size of the child's body. When the child's body is small, the slide member is fixed at the lowest height as shown in FIG. 2(a). Fix the slide member at the highest height. The slide member 4 can be fixed at multiple height positions.

The slide member 4 has a pair of shoulder belt holes 43 through which the pair of shoulder belts 12 pass, an upright wall portion 41 for protecting the back of the child's head, and protruding forward from both ends of the upright wall portion 41, and a pair of side walls 42 for lateral protection of the child's head. The slide member 4 preferably functions as a headrest that protects the child's head, but it does not have to be a headrest. In that case, the standing wall portion 41 may be a central region and have a pair of shoulder belt passing holes 43 . Further, the side wall portions 42 are side regions and are provided on both sides of the central region. In other words, the side regions need only be provided on both sides of the shoulder belt through-hole 43, and need not protrude forward.

As described above, the vertical wall portion 41 is formed with a pair of shoulder belt holes 43 through which the pair of shoulder belts 12 are passed. Each shoulder belt through-hole 43 has a horizontally long cross section extending in the width direction of the seat body 11 and corresponds to the cross section of the shoulder belt 12 .

A pair of vertically extending openings 32 ( FIG. 3 ) are provided at positions facing the shoulder belt holes 43 of the backrest portion 3 . As a result, each shoulder belt 12 passes through the shoulder belt through hole 43 of the slide member 4 and the opening 32 of the backrest portion 3 .

Referring particularly to FIG. 2 , it is preferable that the pair of side wall portions 42 have their lower ends located above the shoulder belt hole 43 and their upper ends approximately aligned with the upper ends of the vertical wall portions 41 . Also, referring to FIG. 1, the pair of side wall portions 42 includes an inner portion 42a that contacts the child's head and an outer portion 42b that is farther from the child. Specifically, the inner portion 42 a faces the standing wall portion 41 , and the outer portion 42 b faces the side opposite to the standing wall portion 41 . A pair of shoulder belt holders 5 are preferably provided on the outer portion 42b. The shoulder belt holding portion 5 is a member that holds the shoulder belt 12 in an open state, the details of which will be described later.

FIG. 3 is a rear view showing the rear surface of the backrest portion 3. FIG. One end portion 12t of the shoulder belt 12 passed through the shoulder belt through hole 43 extends upward beyond the shoulder belt through hole 43, and is stretched over the pin 33 to turn downward from the pin 33 and further extend. The pair of one end portions 12t are connected to one adjustment belt 16 below the slide member 4 . Therefore, the pair of one end portions 12t and one adjustment belt 16 are arranged in a Y shape. However, in order to facilitate understanding of the drawing, FIG. 3 omits the Y-shaped connecting region and shows only a portion of each belt.

The pin 33 is attached and fixed to the backrest portion 3 above the opening 32 . The pins 33 are arranged in the left and right regions of the backrest portion 3 and extend in the width direction of the backrest portion 3 . Note that FIG. 3 shows a rear member 44 arranged behind the opening 32 and having a shape larger than the width dimension of the opening 32 . Left and right regions of the rear member 44 are formed with shoulder belt through holes 43 , respectively.

4(a) and 4(b) are schematic diagrams of the arrangement of the belts as viewed from the side of the seat body. A midway portion of the adjustment belt 16 extends in the front-rear direction through the seat surface portion 2 . A rear end of the adjustment belt 16 protrudes rearward from the seat surface portion 2 and is connected to a pair of one end portions 12t, 12t. The front end of the adjustment belt 16 is passed through a belt lock mechanism 17 provided in the front region of the seat portion 2 . A belt lock mechanism 17 locks an arbitrary position of the adjustment belt 16 . Further, the belt lock mechanism 17 is provided with an operator 18 that unlocks the adjustment belt 16 while the operator of the child seat 1 (a child's guardian) operates the operator 18 . With a slight force, the adjusting belt 16 can then be moved rearwards and the pair of shoulder belts 12 lengthened. Alternatively, when the operator pulls out the front end 16f of the adjustment belt 16 while operating the operator 18, the adjustment belt 16 moves forward and the pair of shoulder belts 12 is shortened. The operator 18 is a button or lever, and the adjusting belt 16 is allowed to move freely with respect to the belt lock mechanism 17 while the operator presses the button or tilts the lever.

Thereby, the adjusting belt 16 and the belt locking mechanism 17 constitute a belt length adjusting mechanism. A belt length adjusting mechanism adjusts the length of the pair of shoulder belts 12 . In this embodiment, the belt lock mechanism 17 locks the adjustment belt 16 while the operator 18 is not operated, that is, in a normal state. Therefore, the adjustment belt 16 is fixed so as not to move relative to the belt lock mechanism 17 .

As shown in FIG. 1, pads 21 are attached to the pair of shoulder belts 12, respectively.

5 and 6 are diagrams showing a pair of pads 21 extracted. In particular, in FIG. 6, for ease of understanding, the left pad 21 is vertically folded in two, and the right pad 21 is unfolded. The pad 21 may be a cloth material vertically folded in two as shown in FIG. 6, or may be a cloth material sewn into a cylindrical shape, for example. The pad 21 has one upper end 21u near the backrest 3 (FIG. 4), the other lower end farther from the backrest (outer end 21t, inner end 22t), and an inner portion that contacts the child. It has a cushioning material 22 provided and an outer portion 21v remote from the child.

The cushion material 22 and the outer portion 21v form a cloth tube (and a tube hole). Shoulder belt 12 extends through a tubular hole in pad 21 . Therefore, the pad 21 is relatively slidable along the shoulder belt 12 . A cushioning material 22 sewn to the inner portion of the pad 21 (the planar portion that contacts the shoulder of the child) softens the contact between the shoulder belt 12 and the shoulder of the child. In addition, it should be understood that sewing in the present embodiment is one aspect of coupling or connection.

Pad 21 is connected to slide member 4 via connecting member 23 . The connecting member 23 extends vertically along the shoulder belt 12 , and a lower end 23 d of the connecting member 23 is sewn to an upper end of the pad 21 . The connecting member 23 is a belt narrower than the shoulder belt 12, is passed through the aforementioned shoulder belt through-hole 43, and extends to the rear surface of the slide member 4 as shown in FIG. The other end 23u of the upper side of the connecting member 23 is sewn into an annular shape, and a pin 45 is passed therethrough. The pin 45 extends in the width direction of the slide member 4 and is attached to the rear member 44 .

The connecting member 23 may be connected to any portion of the seat body 11 to prevent the pad 21 from falling off along the shoulder belt 12. 3 may be directly connected.

As shown in FIG. 5, the pair of shoulder belts 12 are provided with latches 24 at intermediate positions. The locking device 24 has a ring portion 24r suitable for passing the operator's finger, and two shaft portions 24s and 24t. The locking tool 24 is arranged on the opposite side (lower side) of the connecting member 23 on the upper side when viewed from the pad 21 .

The ring portion 24r forms a hole large enough for one adult finger to enter. The ring portion 24r also serves to engage with the shoulder belt holding portion 5 described above. The shaft portions 24s and 24t extend side by side in parallel, and the shoulder belt 12 is passed between these shaft portions. The shaft portion 24t is located inside the shoulder belt 12 (closer to the child). The shaft portion 24s and the ring portion 24r are located outside the shoulder belt 12 (on the far side from the child). Further, the shaft portion 24t is positioned on the upper side, the ring portion 24r is positioned on the lower side, and the shaft portion 24s is positioned between the shaft portion 24t and the ring portion 24r. Thereby, the locking tool 24 is slidably attached to the shoulder belt 12 . The length of the shaft portion 24t is slightly larger than the width of the shoulder belt 12, and an elongated hole that fits the cross-sectional shape of the shoulder belt 12 is defined between the shaft portion 24t and the shaft portion 24s.

The locking device 24 is connected to the pad 21 via the elastic member 25 . The elastic member 25 is a belt narrower than the shoulder belt 12 and extends inside the cylindrical hole of the pad 21 . An upper end 25 u of the elastic member 25 is sewn to the upper region of the pad 21 . The other lower end of the elastic member 25 is sewn into an annular shape, through which the shaft portion 24s of the locking device 24 is passed. Note that the elastic member 25 overlaps the outer surface of the shoulder belt 12 .

The elastic member 25 is, for example, a belt-like rubber cord made by knitting rubber threads, and is elastically stretchable as indicated by the phantom lines in FIG. Therefore, the other end region of the elastic member 25 is elastically pulled out from the other end portion of the lower side of the pad 21 .

5, the other end of the pad 21 includes an inner end 22t that contacts the child's shoulder and an outer end 21t far from the child. including. The inner end portion 22t is formed in a tongue shape so as to protrude from the outer end portion 21t. With the elastic member 25 in its unstretched original length, the tongue-like inner end 22t is interposed between the child's shoulder and the anchor 24. As shown in FIG. This ensures that the rigid fasteners 24 do not rest against the child's shoulders. The inner end portion 22t corresponds to the lower end portion of the cushion material 22. As shown in FIG.

The elastic member 25 regulates the locking tool 24 so that it does not fall off. Thereby, the locking device 24 is arranged adjacent to the other end of the pad 21 . As a modified example (not shown), one end 25u of the elastic member 25 may be coupled to one end 23d of the connecting member 23 instead of the pad 21 . Alternatively, one end 25u may be coupled with the backrest portion 3 or the slide member 4. As shown in FIG.

As shown in FIG. 4(a), an anti-slip layer 21s is provided on the surface of the inner portion of the pad 21 that contacts the child's shoulder. The non-slip layer 21s is made of a material having a high coefficient of friction, such as rubber, and is formed by anti-slip processing applied to the inner portion of the pad 21 . The pads 21 thereby firmly grip the child's shoulders.

Next, the action of the shoulder belt structure will be described.

In the normal state shown in FIG. 5, the shoulder belt 12 has an appropriate length. A shoulder belt 12 of appropriate length extends along the front side of the shoulders of a child (not shown) seated on the seat body 11 . The lower ends of the pair of shoulder belts 12 are connected to the crotch belt 13 and the pair of waist belts 14 via connectors 15 (see FIG. 1) to restrain the child. The elastic member 25 is brought to its original length and suspends the fastener 24 . The locking tool 24 is in contact with the outer surface of the inner end 22t with the shaft portion 24t facing upward and the ring portion 24r facing downward.

When the length of the shoulder belt 12 is insufficient, the operator operates the operating element 18 with one hand, and holds the pair of fasteners 24 with the other hand as indicated by the arrows in FIG. 4(a). It is good to raise it and pull it to the front F in FIG.4(b). As a result, the belt lock mechanism 17 allows the adjustment belt 16 to move freely, the adjustment belt 16 slides rearward in the direction indicated by the arrow in FIG. is pulled forward from the backrest portion 3. This lengthens the shoulder belt 12 . It should be noted that when the operator pulls the locking device 24, the elastic member 25 is elastically extended, and the locking device 24 moves forward away from the inner end 22t. When the operator releases the locking device 24, the elastic member 25 returns to its original length and the locking device 24 is returned to the outer surface of the inner end 22t.

According to this embodiment, since the shoulder belt 12 is covered with the pad 21, it is difficult for the operator to directly access the shoulder belt 12. Can be pulled out easily. Therefore, smooth adjustment of the shoulder belt length is realized, and the labor of the operator is reduced.

If the length of the shoulder belt 12 is excessive, the operator should operate the operator 18 with one hand, and grasp the front end 16f of the adjustment belt 16 with the other hand and pull it forward. As a result, the belt lock mechanism 17 allows the free movement of the adjusting belt 16, the adjusting belt 16 slides forward in the direction opposite to the direction indicated by the thin arrow in FIG. It is drawn rearward from the backrest portion 3 through the hole 43 . The shoulder belt 12 is thereby shortened.

The shoulder belt structure of this embodiment includes an adjustable belt 16 and a belt lock mechanism 17 provided on a seat body 11 on which a child sits, and a pair of shoulder belts 12 whose lengths are adjusted by the adjustable belt 16 and belt lock mechanism 17. 12, a pad 21 which is a member slidably provided on the shoulder belt 12 and contacts the shoulders of the child seated on the seat body 11, one end of which is connected to the seat body 11 and the other end of which is connected to the pad 21. a connecting member 23 that engages with the shoulder belt 12, a locking device 24 that slidably locks the shoulder belt 12 and pulls out the shoulder belt 12, and an elastic member 25 that has one end connected to the pad 21 and the other end connected to the locking device 24. and

The elastic member 25 of this embodiment is passed through the pad 21 , one end is coupled with one end above the pad 21 , and the other end is drawn below the pad 21 and connected to the shaft 24 s of the locking device 24 . be done.

The other lower end of the pad 21 is tongue-shaped so that the inner end 22t that contacts the child's shoulder protrudes from the outer end 21t. In the original length of the elastic member 25, the tongue-shaped inner end portion 22t is located inside (closer to the child) than the locking device 24. As shown in FIG. This allows the inner end 22t to be interposed between the child's shoulder and the locking device 24, avoiding the hard locking device 24 coming into contact with the child's shoulder.

As shown in FIG. 5, the shoulder belt 12 is passed through the shoulder belt through hole 43. As shown in FIG. When the shoulder belt 12 is adjusted to be shortened, the shoulder belt 12 is pulled rearward of the backrest portion 3 through the shoulder belt through-hole 43, but since the pair of pads 21 are connected to the elastic members 25, the shoulder belt 12 is pulled in. It cannot pass through the belt passing hole 43. Therefore, the pad 21 is not drawn rearward of the backrest portion 3 via the shoulder belt through-hole 43 .

The surface of the inner portion of the pad 21 that contacts the child's shoulder is subjected to anti-slip processing to form an anti-slip layer 21s. The child's shoulders are thereby gripped by the pad 21 .

(Regarding the shoulder belt holder)
The shoulder belt holding portion 5 will be described with reference to FIGS. 1, 2 and 7(a) to (c).

Particularly, as shown in FIGS. 1 and 2, the pair of shoulder belt holding portions 5 are provided on the pair of side wall portions 42 of the slide member 4, respectively, and hold the pair of shoulder belts 12 in an open state. Specifically, the pair of shoulder belt holding portions 5 are provided on the outer side portions 42 b of the pair of side wall portions 42 . As a result, the pair of shoulder belt holding portions 5 are provided outside the pair of shoulder belt through holes 43 and in front of the shoulder belt through holes 43 . Further, the shoulder belt holding portion 5 is provided at the same height as the shoulder belt through-hole 43 or at a higher position. By providing the shoulder belt holding portion 5 above, outside, and in front of the pair of shoulder belt passing holes 43 in this way, the opening amount of the shoulder belt 12 can be increased.

An example of the shape of the shoulder belt holding portion 5 will be described. The shoulder belt holding portion 5 is provided as a member separate from the side wall portion 42 and attached to the outer side portion 42 b of the side wall portion 42 . The material of the shoulder belt holding portion 5 is not particularly limited, but is preferably a soft resin such as thermoplastic polyurethane (TPU).

7A to 7C, the shoulder belt holding portion 5 includes a base portion 51 and a hook portion 52 rising upward from the base portion 51. As shown in FIG. The pedestal portion 51 is fixed to the outer portion 42 b of the side wall portion 42 . A method of fixing the base portion 51 to the side wall portion 42 is not limited. For example, the shoulder belt holding portion 5 may have the pedestal portion 51 attached to the side wall portion 42 with a connector such as a screw, or may be attached to the cover of the side wall portion 42 by sewing. The pedestal portion 51 of 5 may be embedded in the cover, and only the hook portion 52 may protrude outward from a cut provided in the cover.

The hook portion 52 engages with a pair of fasteners 24 provided on the shoulder belt 12 . The hook portion 52 has a column portion 53 and a protruding portion 54 that protrudes from the column portion 53 toward the rear (to the right in the drawing). The column portion 53 is a catch portion when the locking tool 24 is engaged, and the protruding portion 54 functions as a retaining portion. A through hole 55 may be provided in a portion where the protruding portion 54 overlaps the pedestal portion 51 in the vertical direction. Although the shape of the shoulder belt holding portion 5 has been described above, it is merely an example, and various shapes can be adopted as long as the shape holds the shoulder belt 12 .

(About the action of the shoulder belt holder)
Next, a method for holding the shoulder belt 12 in the shoulder belt holding portion 5 will be described with reference to FIGS. 8(a) to 8(c).

FIG. 8( a ) shows a state in which the shoulder belt 12 is placed on the seat body 11 . When the shoulder belt 12 is held by the shoulder belt holding portion 5, as shown in FIG. 8(b), a finger is put on the locking member 24 of the shoulder belt 12 to move the shoulder belt 12 to the outside of the seat body 11. As shown in FIG. The fastener 24 is connected to the shoulder belt 12 via an elastic member 25 . Therefore, the shoulder belt 12 also spreads outward following the movement of the locking device 24 . Further, the locking member 24 is pulled to elastically extend the elastic member 25, and as shown in FIG. The member 25 is restored to its original length. Thereby, the shoulder belt 12 can be easily held in an open state.

In this way, the shoulder belt 12 is held in the open state by the shoulder belt holding part 5, and the child can be seated on the seat body 11 or taken down from the seat body 11. - 特許庁

As a result, the shoulder belt 12 can be held in an open state when the child is seated on or put down on the seat body 11, so that the shoulder belt 12 is not put under the child, so that the child can be easily put on and taken off. It can be carried out. In addition, since the locking device 24 is connected to the shoulder belt 12 via the elastic member 25, the elastic expansion and contraction of the locking device 24 can be utilized when hooking the locking device 24 on the shoulder belt holding part 5. It becomes possible to easily hold the stopper 24 .

A conventional child seat has a holding portion for holding a shoulder belt on the side of the seat body. Therefore, when the slide member is moved upward as the child grows, the holding position of the shoulder belt is considerably lower than the shoulder belt through-hole, and the holding position of the shoulder belt relative to the shoulder belt through-hole and the degree of opening of the shoulder belt. was displaced. Therefore, the structure was not adapted to the growth of the child, and it was inconvenient to use. On the other hand, in the child seat 1 of the present embodiment, the shoulder belt holding portion 5 is provided on the slide member 4, so even if the slide member 4 is displaced as the child grows, the shoulder with respect to the shoulder belt insertion hole 43 does not move. The holding position of the belt 12 and the degree of opening of the shoulder belt 12 are not displaced. Therefore, it adapts to the growth of the child.

Further, as described above, the child seat 1 of the present embodiment can be put into a bed state by reclining the backrest portion 3 .
