Description

  The present invention relates to a child seat fixed to a vehicle seat by webbing.

  When an infant or infant rides on a vehicle, a child seat is required to be attached to the seat and be seated on the seat. There are several types of such child seats classified based on the weight of the child, etc. Among them, child seats for infants are particularly called baby seats, and an example of this is disclosed in Patent Document 1 below. Has been.

  The baby seat includes a seat portion and a backrest portion that are connected so as to be substantially L-shaped in a side view, and is attached to the seat so that the baby is seated toward the rear of the vehicle. At this time, the baby seat is supported by the shoulder side webbing from the tongue to the through anchor among the webbing of the three-point seat belt device provided on the seat, and the backrest is supported from the tongue to the anchor plate. The seat is pressed from above by the lap-side webbing until the seat is fixed to the seat.

  By the way, at both ends in the width direction of the baby seat, wall-shaped side wall portions are provided for protecting the baby from impact from the side. Therefore, the lap side webbing passes above the side wall portion, and the seat portion is fixed to the seat by pressing the upper end portion of the side wall portion into the seat. However, this webbing only fixes the baby seat to the seat, and it is a belt separately provided on the baby seat that restrains the baby on the baby seat.

However, such a conventional baby seat has a configuration in which the wrap-side webbing passes over the side wall portion, and thus the wrap-side webbing passes over the infant. For this reason, every time the baby gets in and out, the baby seat must be fixed to the seat by webbing or released, which is troublesome.

  In view of the above facts, the present invention has an object of obtaining a child seat that can be easily operated when getting on and off an occupant.

Child seat of the invention according to claim 1, together with the longitudinal direction backrest portion is provided at a rear portion is placed on the seat in the opposite state with respect to the longitudinal direction of the vehicle seat, the previous SL seat wherein the rear surface side of the backrest portion shoulder side webbing is wound around over the entire width of the backrest portion in a placement state, the at tension of the shoulder-side webbing held down on the seat on the seat a seat main body to be fixed, while being erected from both ends in the width direction of the seat main body, and the shoulder-side webbing through the data ring is capable upper end passage of the lap side webbing opposite to an opening A pair of side walls having notches , and further, the lap side webbing that passes through the pair of notches with the bottom of the notches set substantially flush with the surface of the sheet main body. The above The pair of notches are positioned on the front side of the vehicle with respect to the buckle that is provided on the side of the seat and holds the tongue in the mounted state on the seat. The formation position of the notch in the side wall is set .

  In the child seat according to the first aspect, the seat body is placed on the vehicle seat in a state where the front-rear direction is opposite to the front-rear direction of the vehicle seat. In this state, when the shoulder side webbing, which is one side of the webbing through the tongue, is wrapped around the back side of the backrest part provided at the rear part of the seat main body part, the sheet main body part by the tension of the shoulder side webbing Is pressed against the vehicle seat. As a result, the seat main body is fixed on the seat of the vehicle, and the occupant sits on the fixed seat main body. Here, “sitting down” includes not only sitting (sitting) but also sleeping on the back.

  On the other hand, the seat body portion includes a pair of side wall portions. For example, when an impact from the side is received, the occupant is protected by these side wall portions.

Here, in this child seat, a notch is provided in the side wall. Since this notch is formed by notching the upper end of the side wall, an opening that opens upward is formed. When the child seat is fixed to the seat, the lap side webbing on the opposite side of the shoulder side webbing is attached to the buckle through the tongue toward the notch located approximately on the vehicle front side of the buckle in the seated state. It extends from the held tongue substantially to the rear side of the vehicle, and enters both of the notches from the openings of both notches. As a result, the lap-side webbing passes through one of the cutouts, passes over the sheet main body, and further passes through the other cutout. In this way, the lap side webbing passes over the sheet main body.
Here, the bottom of the cutout portion on the side opposite to the opening is substantially flush with the surface of the sheet main body. Therefore, when fixing the child seat to the seat, when the enter the lap side webbing passing over the sheet body portion to the cutout portion from the opening, along physician lap side webbing on the surface of the sheet body (i.e., the lap side webbing physician crawling over the surface of the sheet main body), the lap side webbing contacts the surface of the sheet main body portion. Accordingly, when the occupant sits on the child seat in the fixed state, the lap-side webbing is sandwiched between the occupant and the seat body. That is, in a state where the seat body is fixed by the webbing, the lap side webbing passes under the occupant.

  For this reason, the lap side webbing does not become an obstacle when the occupant is put on the child seat or when the occupant is lowered from the child seat. Therefore, it is not necessary to fix the seat main body portion by webbing or to release the fixation every time the passenger gets on and off, and the operation of getting on and off the passenger is simple.

  Further, since the lap-side webbing has entered the notch, when the child seat moves in the front-rear direction with respect to the seat, the lap-side webbing is formed on the inner wall of the notch (the part other than the opening and bottom of the notch). have a finger in the pie. Therefore, the movement of the seat body in the front-rear direction relative to the seat is limited. For this reason, the child seat is securely fixed to the seat.

  In addition, since the notch is only partly cut away from the side wall so that the lap-side webbing can pass therethrough, it is also easy to form the notch.

  The child seat of the invention according to claim 2 is provided with a backrest portion at the rear, and is placed on the seat in a state where the front-rear direction is opposite to the front-rear direction of the seat of the vehicle. A shoulder-side webbing is hung across the entire width direction of the backrest portion on the back side of the backrest portion in a mounted state, and is pressed onto the seat by the tension of the shoulder-side webbing and fixed on the seat. And a notch portion that is erected from both ends in the width direction of the seat body portion and that is open at the upper end portion so that the lap side webbing on the opposite side of the shoulder side webbing can pass through the tongue. A pair of side walls having a pair of inner walls having a plane parallel to each other, one facing the front of the vehicle and the other facing the rear of the vehicle when mounted on the seat. The And forming the notch portion in the side wall portion so that the notch portion is positioned on the vehicle front side with respect to a buckle that is provided on the side of the seat and holds the tongue in the mounted state on the seat. It is characterized by setting the position.

  In the child seat according to the second aspect, the seat main body is placed on the vehicle seat in a state where the front-rear direction is opposite to the front-rear direction of the vehicle seat. In this state, when the shoulder side webbing, which is one side of the webbing through the tongue, is wrapped around the back side of the backrest part provided at the rear part of the seat main body part, the sheet main body part by the tension of the shoulder side webbing Is pressed against the vehicle seat. As a result, the seat main body is fixed on the seat of the vehicle, and the occupant sits on the fixed seat main body. Here, “sitting down” includes not only sitting (sitting) but also sleeping on the back.
  On the other hand, the seat body portion includes a pair of side wall portions. For example, when an impact from the side is received, the occupant is protected by these side wall portions.
  Here, in this child seat, a notch is provided in the side wall. Since this notch is formed by notching the upper end of the side wall, an opening that opens upward is formed. When the child seat is fixed to the seat, the lap side webbing on the opposite side of the shoulder side webbing is attached to the buckle through the tongue toward the notch located approximately on the vehicle front side of the buckle in the seated state. It extends from the held tongue substantially to the rear side of the vehicle, and enters both of the notches from the openings of both notches. As a result, the lap-side webbing passes through one of the cutouts, passes over the sheet main body, and further passes through the other cutout. In this way, the lap side webbing passes over the sheet main body.
  In this way, the lap-side webbing passes through the cutouts on both side walls and passes over the seat body, so when the occupant sits on the child seat in the fixed state, the lap-side webbing is placed between the occupant and the seat body. Sandwiched. That is, in a state where the seat body is fixed by the webbing, the lap side webbing passes under the occupant.
  For this reason, the lap side webbing does not become an obstacle when the occupant is put on the child seat or when the occupant is lowered from the child seat. Therefore, it is not necessary to fix the seat main body portion by webbing or to release the fixation every time the passenger gets on and off, and the operation of getting on and off the passenger is simple.
  Further, the lap-side webbing is inserted into the notch, and both inner walls of the notch are provided with mutually parallel flat portions facing each other substantially in the vehicle front-rear direction with the child seat placed on the seat. For this reason, when the child seat attempts to move in the front-rear direction with respect to the seat, the lap-side webbing effectively interferes with the inner wall portion of the notch portion. Therefore, the movement of the seat body in the front-rear direction with respect to the seat is limited. For this reason, the child seat is securely fixed to the seat.
  In addition, since the notch is only partly cut away from the side wall so that the lap-side webbing can pass therethrough, it is also easy to form the notch.

  According to a third aspect of the present invention, a child seat according to a third aspect is provided with a backrest portion at the rear, and is placed on the seat in a state where the front-rear direction is opposite to the front-rear direction of the vehicle seat. A shoulder-side webbing is hung across the entire width direction of the backrest portion on the back side of the backrest portion in a mounted state, and is pressed onto the seat by the tension of the shoulder-side webbing and fixed on the seat. And a notch portion that is erected from both ends in the width direction of the seat body portion and that is open at the upper end portion so that the lap side webbing on the opposite side of the shoulder side webbing can pass through the tongue. A pair of side walls having a pair of inner walls having a plane parallel to each other, one facing the front of the vehicle and the other facing the rear of the vehicle when mounted on the seat. The And the bottom of the notch is set substantially flush with the surface of the sheet body, and the lap side webbing passing through the pair of notches is brought into contact with the surface of the sheet body. In addition, in the mounted state on the seat, the notch portion is formed on the side wall portion so that the notch portion is located on the vehicle front side with respect to the buckle provided on the side of the seat and holding the tongue. It is characterized by setting.

  In the child seat according to the third aspect, the seat main body is placed on the vehicle seat in a state where the front-rear direction is opposite to the front-rear direction of the vehicle seat. In this state, when the shoulder side webbing, which is one side of the webbing through the tongue, is wrapped around the back side of the backrest part provided at the rear part of the seat main body part, the sheet main body part by the tension of the shoulder side webbing Is pressed against the vehicle seat. As a result, the seat main body is fixed on the seat of the vehicle, and the occupant sits on the fixed seat main body. Here, “sitting down” includes not only sitting (sitting) but also sleeping on the back.
  On the other hand, the seat body portion includes a pair of side wall portions. For example, when an impact from the side is received, the occupant is protected by these side wall portions.
  Here, in this child seat, a notch is provided in the side wall. Since this notch is formed by notching the upper end of the side wall, an opening that opens upward is formed. When the child seat is fixed to the seat, the lap side webbing on the opposite side of the shoulder side webbing is attached to the buckle through the tongue toward the notch located approximately on the vehicle front side of the buckle in the seated state. It extends from the held tongue substantially to the rear side of the vehicle, and enters both of the notches from the openings of both notches. As a result, the lap-side webbing passes through one of the cutouts, passes over the sheet main body, and further passes through the other cutout. In this way, the lap side webbing passes over the sheet main body.
  Here, the bottom of the cutout portion on the side opposite to the opening is substantially flush with the surface of the sheet main body. For this reason, when the child seat is fixed to the seat, if the lap-side webbing that passes over the seat main body is inserted into the notch from the opening, the lap-side webbing extends along the surface of the seat main body (that is, the lap-side webbing). The wrap side webbing is in contact with the surface of the sheet main body. Accordingly, when the occupant sits on the child seat in the fixed state, the lap-side webbing is sandwiched between the occupant and the seat body. That is, in a state where the seat body is fixed by the webbing, the lap side webbing passes under the occupant.
  For this reason, the lap side webbing does not become an obstacle when the occupant is put on the child seat or when the occupant is lowered from the child seat. Therefore, it is not necessary to fix the seat main body portion by webbing or to release the fixation every time the passenger gets on and off, and the operation of getting on and off the passenger is simple.
  Further, the lap-side webbing is inserted into the notch, and both inner walls of the notch are provided with mutually parallel flat portions facing each other substantially in the vehicle front-rear direction with the child seat placed on the seat. For this reason, when the child seat attempts to move in the front-rear direction with respect to the seat, the lap-side webbing effectively interferes with the inner wall portion of the notch portion. Therefore, the movement of the seat body in the front-rear direction with respect to the seat is limited. For this reason, the child seat is securely fixed to the seat.
  In addition, since the notch is only partly cut away from the side wall so that the lap-side webbing can pass therethrough, it is also easy to form the notch.

  The child seat of the invention according to claim 4 is the child seat according to any one of claims 1 to 3, wherein an opening width at an upper end portion of the side wall portion is set larger than a width dimension of the webbing. It is characterized by that.

In the child seat according to claim 4, since the opening width of the upper end portion of the cutout portion (that is, the opening portion of the cutout portion) is larger than the width dimension of the webbing, the upper end of the cutout portion can be easily inserted into the cutout portion. Can pass through. In addition, as described above, the child seat can be fixed to the seat only by inserting the webbing into the notch from the opening of the notch, so that the operation of fixing the child seat to the seat is also easy.

A child seat according to a fifth aspect of the present invention is the child seat according to any one of the first to fourth aspects, wherein a protruding portion that protrudes inward in the opening width direction of the cutout portion is an inner peripheral edge of the cutout portion. It is characterized in that it is provided on the opening side of the part.

In the child seat according to claim 5 , the notch is provided with a protrusion. Since this protrusion is provided on the opening end side of the notch portion toward the inside in the opening width direction, the opening portion of the notch portion is narrowed. For this reason, even if the child seat tries to move relative to the seat, the inner wall of the notch interferes with the webbing (the movement of the seat body in the front-rear direction with respect to the seat is restricted), and this protrusion also acts on the webbing. Interfere (the vertical movement of the seat body relative to the seat is restricted). Thus, in this child seat, the webbing is difficult to come off from the notch, so that the child seat is more securely fixed to the seat.

  As described above, the child seat according to the present invention has an excellent effect that the work for getting on and off the occupant is simple.

  FIG. 1 is a perspective view of a baby seat 10 as a child seat according to the first embodiment of the present invention. Moreover, the seat part 22 which comprises the baby seat 10 is shown by the side view in FIG. 2, and also the seat part 22 is shown by the front view in FIG.

  The baby seat 10 includes a backrest portion 20 and a seat portion 22 as a seat body portion. The backrest portion 20 and the seat portion 22 are substantially L-shaped in a side view (viewed from the left side of the vehicle).

  A pair of belt insertion holes (not shown) is provided at a substantially central portion of the backrest portion 20, and both end portions of the shoulder belt 24 are attached. The shoulder belt 24 has a substantially V-shaped loop that is folded back through a tongue 26 so that the head of the infant 12 can pass through. A plurality of belt insertion holes are provided along the longitudinal direction of the backrest portion 20 so that the positions of both end portions of the shoulder belt 24 can be adjusted according to the body size of the infant 12. Further, a buckle 28 is provided upright at a substantially central portion of the seat portion 22. The tongue 26 is inserted into the buckle 28 and is held by the buckle 28.

  Side wall portions 30 are respectively provided at both end portions of the backrest portion 20 and the seat portion 22 so as to stand on both sides of the seated infant 12. Moreover, the side wall part 30 is comprised by the support part 30A provided in the backrest part 20 side, and the support part 30B provided in the seat part 22 side.

  Cutout portions 32 are formed in the support portions 30B. The notch 32 has a substantially rectangular shape in a side view when the upper end side of the support portion 30B near the base end side of the seat portion 22 (near the coupling portion between the backrest portion 20 and the seat portion 22) is cut out. For this reason, it is opened upward. As described above, the notch 32 includes the opening 34, the bottom 36 opposite to the opening 34, and a pair of opposed inner walls 38. Moreover, the opening width dimension of the notch part 32 is longer than the width direction dimension of the webbing 18 of the seatbelt apparatus 14, and the webbing 18 can pass therethrough. Further, the bottom portion 36 is substantially flush with the seat surface portion 42 of the seat portion 22.

  A protrusion 40 is provided on the inner wall 38 on the proximal end side of the seat 22. The protrusion 40 is provided on the opening 34 side of the notch 32 and protrudes toward the distal end side of the baby seat 10 (toward the rear of the vehicle when the baby seat 10 is fixed as shown in FIG. 1). The inner peripheral surfaces of the notch 32 and the protrusion 40 are smooth (see FIG. 2).

  Next, the operation of the present embodiment will be described.

  When the baby seat 10 having the above configuration is fixed to the vehicle seat 16, first, the baby seat 10 is placed on the seat surface of the vehicle seat 16 so that the front end side of the seat portion 22 faces the rear of the vehicle.

Next, the tongue 44 of the seat belt device 14 is inserted into the buckle 46. Thereby, the webbing 18 is pulled out from the winding device (not shown), and the tongue 44 is held by the buckle 46. At this time, the shoulder side webbing 18 </ b> A on the winding device side of the webbing 18 as viewed from the tongue 44 is wound around the back surface side (side facing the vehicle front side) of the backrest 20. Thereby, the backrest part 20 is supported by the shoulder side webbing 18A from the back side. Further, the lap side webbing 18 </ b> B on the anchor plate (not shown) side of the webbing 18 as viewed from the tongue 44 is passed over the seat portion 22 . Since tension is applied to the webbing 18 by the winding device, the seat portion 22 is pressed against the seat 16. Thereby, the baby seat 10 is fixed to the seat 16.

  Next, the baby 12 is seated on the baby seat 10 in the fixed state. In this case, first, the infant 12 is seated on the baby seat 10 so as to straddle the buckle 28. Thereafter, the tongue 26 is inserted into the buckle 28 through the head of the infant 12 into the substantially V-shaped loop of the shoulder belt 24. Thereby, the tongue 26 is held by the buckle 28, and the infant 12 is restrained by the baby seat 10 by the shoulder belt 24.

  Here, in the baby sheet 10, the notch 32 is provided in the support 30B. The notch 32 has an opening 34 that opens upward. Further, the bottom 36 of the notch 32 is substantially flush with the seating surface 42. For this reason, when the baby seat 10 is fixed to the seat 16, the lap side webbing 18 </ b> B enters the notch 32 through the opening 34, so that the lap side webbing 18 </ b> B crawls on the seat surface part 42 (see FIG. 3).

  For this reason, when the baby 12 is put on the baby seat 10 in the fixed state, the wrap side webbing 18B does not become an obstacle, and when the baby 12 is put on the baby seat 10, the baby 12 is placed on the lap side webbing 18B. Get on (the webbing 18 passes below the infant 12).

  Therefore, the operation of seating the infant 12 on the baby seat 10 is completed only by restraining the infant 12 on the baby seat 10 by the shoulder belt 24 (inserting the tongue 26 into the buckle 28) (after restraining the infant 12 again). The baby sheet 10 may not be fixed by the webbing 18). For this reason, the operation | work which puts the infant 12 on the baby seat 10 is easy.

  Further, when the infant 12 is lowered from the baby seat 10, the lap side webbing 18B does not become an obstacle, and the infant 12 can be removed from the baby seat 10 only by removing the shoulder belt 24 (the tongue 26 is detached from the buckle 28). The baby sheet 10 can be lowered (the baby sheet 10 does not need to be released by the webbing 18 before the baby 12 is lowered from the baby sheet 10). Therefore, the operation for lowering the infant 12 from the baby seat 10 is simple.

  In addition, since the baby seat 10 can be fixed to the seat 16 simply by inserting the lap side webbing 18B into the notch 32 from the opening 34, the operation of fixing the baby seat 10 to the seat 16 is also easy. Furthermore, since the notch 32 is only a part of the support 30B, the notch 32 can be easily manufactured.

  Further, since the lap side webbing 18B crawls on the seat surface part 42, the contact area between the lap side webbing 18B and the seat part 22 when the lap side webbing 18B presses the seat part 22 against the seat 16 is large, and the baby seat 10 seat The fixing to 16 is sure.

  Furthermore, when the baby seat 10 is about to move, the inner wall portion 38 of the notch 32 interferes with the wrap-side webbing 18B and restricts the movement of the baby seat 10 in the front-rear direction. Moreover, the protrusion part 40 also interferes with the lap side webbing 18B, and restrict | limits the movement of the baby sheet 10 in the up-down direction. For this reason, the baby seat 10 is more securely fixed to the seat 16.

  In the present embodiment, the protruding portion 40 is provided on the inner wall portion 38 on the proximal end side of the seat portion 22. However, the protruding portion 40 is on the inner wall portion 38 on the distal end side of the seat portion 22. May be provided. Further, the protrusion 40 may be provided on both of the inner wall portions 38 so that the two protrusions face each other.

  In the above embodiment, the present invention is applied to the baby seat 10. However, the scope of the present invention is not particularly limited to such an infant seat, but applied to an infant seat or the like. Also good.

  Next, a second embodiment of the present invention will be described. In the description of the present embodiment, the same reference numerals are assigned to the same parts as those in the first embodiment, and the description thereof is omitted.

  As shown in FIGS. 4 to 6, the baby seat 80 as a child seat according to the present embodiment includes a clip 82 as a holding member. The clip 82 is fixed on the outer surface of the support portion 30 </ b> A on the backrest portion 20 side of the side wall portion 30, above the position where the notch portion 32 is formed and on the rear side of the baby seat 80.

  The clip 82 is formed with a substantially slit-shaped passage portion 84 that is formed in a longitudinal direction substantially along the vertical direction. The longitudinal dimension of the passage part 84 is slightly larger than the width dimension of the webbing 18, and the width dimension of the passage part 84 is larger than the thickness dimension of the webbing 18. The passage portion 84 is notched at the upper end side, and passes through the notch portion of the passage portion 84 when the webbing 18 is passed through the passage portion 84 or when the webbing 18 is extracted from the passage portion 84.

  The baby seat 80 thus provided with the clip 82 is different from the baby seat 10 according to the first embodiment, and the shoulder-side webbing 18A of the webbing 18 is first moved forward (substantially). It passes through the passage portion 84 of the clip 82 from the vehicle rear side. The shoulder-side webbing 18A that has passed through the passage portion 84 is folded back at the passage portion 84 and passes through the cutout portion 32 from the outside of the support portion 30A to which the clip 82 that has passed is attached.

  Further, the webbing 18 that has passed through the shoulder surface part 42 and the other cutout part 32 as the shoulder side webbing 18A is folded back by the tongue 44, and the lap side webbing 18B passes through the cutout part 32 again.

  Unlike the baby seat 10 according to the first embodiment in which the baby seat 80 around which the webbing 18 is hung is hung around the shoulder side webbing 18A on the back side of the backrest portion 20, the pull-out amount of the webbing 18 is increased. Therefore, the fixing work to the seat 16 becomes easy.

  In addition, the baby sheet 80 passes through the notch 32 after the shoulder-side webbing 18 </ b> A passes through the passage portion 84 of the clip 82 and is folded back. Here, when the clip 82 is about to be displaced due to the inadvertent displacement of the baby seat 80, the inner peripheral portion of the passage portion 84 interferes with the portion of the shoulder-side webbing 18A that has passed through the passage portion 84. Due to the interference of the shoulder-side webbing 18A with the clip 82, the displacement of the clip 82 is restricted, and consequently, the inadvertent displacement of the baby seat 80 is restricted. For this reason, the baby seat 80 on the seat 16 can be stably maintained in a fixed state.

  On the other hand, in the vehicle sudden deceleration state, the baby seat 80 tends to sink due to inertia so that the baby seat 80 rotates on the seat 16 substantially forward of the vehicle. Here, in the baby seat 80, as described above, the attachment position of the clip 82 is above the notch 32, and the position is sufficiently separated from the axis of rotation when sinking. For this reason, the above described baby seat 80 is effectively prevented from sinking by the shoulder-side webbing 18A which is folded back after passing through the passage portion 82. Also by this, the baby seat 80 on the seat 16 can stably maintain a fixed state.
