Description

嬰兒車Baby stroller

本揭示之一態樣關於一種嬰兒車。One aspect of the present disclosure relates to a baby stroller.

先前，周知一種具有嬰兒車本體、與受嬰兒車本體支持之座椅之嬰兒車(例如專利文獻1)。於專利文獻1所記載之嬰兒車中，座椅構成為可相對於嬰兒車本體裝卸。於可上述般裝卸座椅之嬰兒車中，為了將座椅固定於嬰兒車本體，一般使用將設置於座椅之座面部及靠背部各者之多個掛鉤帶等之固定具固定於嬰兒車本體(框架)之結構。 [先前技術文獻] [專利文獻] Previously, a stroller having a stroller body and a seat supported by the stroller body is known (e.g., Patent Document 1). In the stroller described in Patent Document 1, the seat is configured to be removable relative to the stroller body. In a stroller with a removable seat as described above, in order to fix the seat to the stroller body, a structure is generally used in which a plurality of hooks or other fasteners provided on the seat surface and backrest of the seat are fixed to the stroller body (frame). [Prior Technical Document] [Patent Document]

[發明所欲解決之問題][The problem the invention is trying to solve]

於如上述般使用多個掛鉤帶而於嬰兒車本體固定座椅之結構中，於座椅之裝卸時，因需要安裝拆卸所有掛鉤帶，故耗費工夫。又，若於複數個部位設置有掛鉤帶，則於座椅之安裝時，使用者難以準確掌握及記憶各掛鉤帶相對於嬰兒車本體之安裝位置。In the structure of fixing the seat to the stroller body using multiple hooks as described above, it takes time to install and remove all the hooks when installing and removing the seat. In addition, if the hooks are provided at multiple locations, it is difficult for the user to accurately grasp and remember the installation position of each hook relative to the stroller body when installing the seat.

本揭示之一態樣之目的在於提供一種可提高座椅之裝卸作業之便利性之嬰兒車。 [解決問題之技術手段] One aspect of the present disclosure is to provide a stroller that can improve the convenience of loading and unloading the seat. [Technical means for solving the problem]

本揭示之一態樣之嬰兒車具備：嬰兒車本體，其具有座椅支持部；及座椅，其受座椅支持部支持；且座椅具有：座面部；及靠背部，其連接於座面部；座椅支持部具有：座面支持部，其支持座面部；及靠背支持部，其支持靠背部；座面部具有：第1面扣件部，其包含設置於與座面支持部對向之面之一個以上之面扣件；靠背部具有：第2面扣件部，其包含設置於與靠背支持部對向之面之一個以上之面扣件；座面支持部具有：第3面扣件部，其包含設置於與第1面扣件部對應之位置之一個以上之面扣件；靠背支持部具有：第4面扣件部，其包含設置於與第2面扣件部對應之位置之一個以上之面扣件。The baby stroller of one aspect of the present disclosure comprises: a baby stroller body, which has a seat support portion; and a seat, which is supported by the seat support portion; and the seat has: a seat portion; and a backrest portion, which is connected to the seat portion; the seat support portion has: a seat support portion, which supports the seat portion; and a backrest support portion, which supports the backrest portion; the seat portion has: a first surface fastener portion, which includes one or more surface fasteners arranged on a surface opposite to the seat support portion; the backrest portion has: a second surface fastener portion, which includes one or more surface fasteners arranged on a surface opposite to the backrest support portion; the seat support portion has: a third surface fastener portion, which includes one or more surface fasteners arranged at a position corresponding to the first surface fastener portion; the backrest support portion has: a fourth surface fastener portion, which includes one or more surface fasteners arranged at a position corresponding to the second surface fastener portion.

於本揭示之一態樣之嬰兒車中，座椅之座面部經由第1面扣件部及第3面扣件部固定於座椅支持部之座面支持部，且座椅之靠背部經由第2面扣件部及第4面扣件部固定於座椅支持部之靠背支持部。如此，藉由使用面扣件而於座椅支持部固定座椅之座面部及靠背部兩者，可相對於座椅支持部平衡良好且穩定地固定座椅。又，因可減少先前一般使用之掛鉤帶等之固定具之數量，故可簡化座椅之拆卸操作。再者，使用者僅以將座椅之座面部及靠背部按壓於座椅支持部之對應位置，即可於座椅支持部固定座椅，僅以將座椅自座椅支持部拉離(拉開)，即可自座椅支持部拆下座椅。因此，根據上述嬰兒車，可提高座椅之裝卸作業之便利性。In a stroller of one aspect of the present disclosure, the seat surface of the seat is fixed to the seat surface support portion of the seat support portion via the first surface fastener portion and the third surface fastener portion, and the backrest portion of the seat is fixed to the backrest support portion of the seat support portion via the second surface fastener portion and the fourth surface fastener portion. In this way, by fixing both the seat surface and the backrest portion of the seat to the seat support portion using the surface fasteners, the seat can be fixed to the seat support portion in a well-balanced and stable manner. In addition, since the number of fasteners such as hooks and the like that are generally used previously can be reduced, the seat removal operation can be simplified. Furthermore, the user can fix the seat to the seat support portion by simply pressing the seat surface and the backrest portion of the seat to the corresponding positions of the seat support portion, and can remove the seat from the seat support portion by simply pulling the seat away (opening) from the seat support portion. Therefore, according to the above-mentioned stroller, the convenience of loading and unloading the seat can be improved.

第1面扣件部所包含之一個以上之面扣件，亦可形成為左右方向之長度長於前後方向之長度之形狀，且第3面扣件部所包含之一個以上之面扣件，亦可具有與第1面扣件部所包含之一個以上之面扣件對應之形狀。通常，於座椅支持部之座面支持部之左右方向之兩側配置有嬰兒車本體之框架。相對於此，不於座面支持部之前方配置上述般之框架。因此，於座面支持部固定(載置)座椅之座面部時，相對於座面支持部之座面部之位置於左右方向偏離之虞較小，另一方面，有相對於座面支持部之座面部之位置於前後方向偏離之虞。假設，於第1面扣件部所包含之面扣件或第3面扣件部所包含之面扣件形成為前後方向之長度長於左右方向之長度之形狀之情形時，即使相對於座面支持部之座椅之座面部之位置稍微於前後方向偏離，第1面扣件部與第3面扣件部亦接觸而相互固定。相對於此，藉由將第1面扣件部及第3面扣件部所包含之面扣件形成為左右方向之長度長於前後方向之長度之形狀，於座面部相對於座面支持部於前後方向偏離之情形時，第1面扣件部與第3面扣件部難以相互接觸。其結果，可抑制座面部以相對於座面支持部於前後方向偏離之狀態固定於座面支持部。One or more surface fasteners included in the first surface fastener portion may also be formed into a shape whose length in the left-right direction is longer than that in the front-back direction, and one or more surface fasteners included in the third surface fastener portion may also have a shape corresponding to one or more surface fasteners included in the first surface fastener portion. Usually, the frame of the stroller body is arranged on both sides of the seat support portion in the left-right direction of the seat support portion of the seat support portion. In contrast, the above-mentioned frame is not arranged in front of the seat support portion. Therefore, when the seat portion of the seat is fixed (mounted) on the seat support portion, the risk of the position of the seat portion relative to the seat support portion deviating in the left-right direction is small, while on the other hand, there is a risk of the position of the seat portion relative to the seat support portion deviating in the front-back direction. Assuming that the surface fastener included in the first surface fastener portion or the surface fastener included in the third surface fastener portion is formed into a shape in which the length in the front-rear direction is longer than the length in the left-right direction, even if the position of the seat surface portion of the chair relative to the seat surface support portion is slightly offset in the front-rear direction, the first surface fastener portion and the third surface fastener portion are in contact and fixed to each other. In contrast, by forming the surface fastener included in the first surface fastener portion and the third surface fastener portion into a shape in which the length in the left-right direction is longer than the length in the front-rear direction, when the seat surface portion is offset in the front-rear direction relative to the seat surface support portion, the first surface fastener portion and the third surface fastener portion are less likely to contact each other. As a result, it is possible to prevent the seat surface portion from being fixed to the seat surface support portion in a state in which the seat surface portion is offset in the front-rear direction relative to the seat surface support portion.

座椅亦可具有設置於連接座面部與靠背部之邊界部附近之連結構件，且嬰兒車本體亦可具有與該連結構件連結之框架構件。根據上述構成，可藉由連結構件一邊將座椅固定於座椅支持部，一邊使座椅之座面部與靠背部之間之邊界部對準適當位置。藉此，例如，藉由以上述邊界部為擺動軸線而使座面部擺動並按壓於座面支持部，可相對於座面支持部容易地將座面部固定於適當位置。同樣，藉由以上述邊界部為擺動軸線而使靠背部擺動並按壓於靠背支持部，可相對於靠背支持部容易地將靠背部固定於適當位置。The seat may also have a connecting structure disposed near the boundary portion connecting the seat portion and the backrest portion, and the stroller body may also have a frame member connected to the connecting structure. According to the above configuration, the seat can be fixed to the seat support portion by the connecting structure while the boundary portion between the seat portion and the backrest portion of the seat is aligned to an appropriate position. Thus, for example, by swinging the seat portion and pressing it against the seat support portion with the above boundary portion as a swing axis, the seat portion can be easily fixed to an appropriate position relative to the seat support portion. Similarly, by swinging the backrest portion and pressing it against the backrest support portion with the above boundary portion as a swing axis, the backrest portion can be easily fixed to an appropriate position relative to the backrest support portion.

第2面扣件部亦可包含複數個面扣件，第4面扣件部亦可包含與第2面扣件部所包含之複數個面扣件對應之複數個面扣件。根據上述構成，可將為了相對於靠背支持部以足夠之強度固定靠背部而需要之各個面扣件之面積小型化。藉此，因可藉由設置大型之面扣件而避免阻礙靠背部之指定部位之通氣性，故可維持乘坐於嬰兒車之嬰幼兒之舒適性。The second surface fastener part may also include a plurality of surface fasteners, and the fourth surface fastener part may also include a plurality of surface fasteners corresponding to the plurality of surface fasteners included in the second surface fastener part. According to the above structure, the area of each surface fastener required to fix the backrest with sufficient strength relative to the backrest support part can be miniaturized. In this way, since the ventilation of the designated part of the backrest can be avoided from being blocked by providing a large surface fastener, the comfort of the infant riding in the baby stroller can be maintained.

第2面扣件部亦可設置於沿靠背部之緣部之位置。根據上述構成，因藉由不於與靠背部之中央部重疊之區域設置面扣件，可確保於靠背部中嬰幼兒之脊背主要接觸之部分之通氣性，故可維持乘坐於嬰兒車之嬰幼兒之舒適性。The second surface fastener part can also be arranged along the edge of the backrest. According to the above structure, since the surface fastener is arranged in the area not overlapping with the central part of the backrest, the ventilation of the part of the backrest that mainly contacts the back of the infant can be ensured, so the comfort of the infant riding in the baby stroller can be maintained.

第2面扣件部亦可至少包含沿靠背部中連接於座面部之側之相反側之緣部設置之面扣件。根據上述構成，藉由於儘量遠離座面部之位置將靠背部固定於靠背支持部，可相對於靠背支持部穩定地支持靠背部。The second surface fastener part may also include at least a surface fastener provided along the edge of the backrest part on the opposite side of the side connected to the seat surface part. According to the above structure, the backrest part can be stably supported relative to the backrest support part by fixing the backrest part to the backrest support part at a position as far away from the seat surface part as possible.

座椅支持部亦可具有：支持框架，其以沿靠背部之緣部中連接於座面部之第1部分以外之第2部分之方式形成；且亦可於靠背部之第2部分設置抑制緣部之變形之抑制構件。根據上述構成，藉由以靠背部之緣部之第2部分沿支持框架之方式將靠背部按壓於靠背支持部之操作，可使靠背部相對於靠背支持部容易且適當地對位。又，因藉由設置於第2部分之抑制構件抑制第2部分之變形，故可容易地進行上述操作、且可提高靠背部之支持穩定性。The seat support part may also include: a support frame formed along the edge of the backrest portion and connected to the second part other than the first part of the seat surface portion; and a restraining member for restraining deformation of the edge may be provided on the second part of the backrest portion. According to the above configuration, the backrest portion can be easily and properly aligned with the backrest support portion by pressing the second part of the edge of the backrest portion along the support frame. In addition, since the deformation of the second part is restrained by the restraining member provided on the second part, the above operation can be easily performed and the support stability of the backrest portion can be improved.

抑制構件亦可為對第2部分進行包邊之被覆構件。根據上述構成，藉由對第2部分進行包邊之被覆構件，可容易且確實地設置上述抑制構件。又，因相對於支持框架沿靠背部之部分之視認性及外觀藉由包邊而提高，故使用者藉由使用包邊部(被覆構件)作為記號，可相對於座椅支持部容易地將靠背部配置於適當位置。 [發明之效果] The restraining member may also be a covering member that is hemmed on the second part. According to the above structure, the restraining member can be easily and reliably set by hemming the second part. In addition, since the visibility and appearance of the portion along the backrest relative to the support frame are improved by hemming, the user can easily arrange the backrest at an appropriate position relative to the seat support portion by using the hemming portion (covering member) as a mark. [Effect of the invention]

根據本揭示之一態樣，可提供一種可提高座椅之裝卸作業之便利性之嬰兒車。According to one aspect of the present disclosure, a baby stroller can be provided that can improve the convenience of loading and unloading the seat.

以下，對本揭示之一實施形態，參照圖式且詳細說明。另，於以下說明中，對同一或相當要件使用同一符號並省略重複之說明。Hereinafter, one embodiment of the present disclosure is described in detail with reference to the drawings. In addition, in the following description, the same symbols are used for the same or equivalent elements and repeated descriptions are omitted.

使用圖1～圖4，對本實施形態之嬰兒車1進行說明。嬰兒車1構成為可折疊。即，嬰兒車1構成為可切換圖1～圖3所示之展開狀態與圖4所示之折疊狀態。展開狀態意指以使嬰幼兒可乘坐於嬰兒車1之方式擴大嬰兒車本體2(展開)之狀態。折疊狀態意指為了緊湊收納嬰兒車1而折疊嬰兒車本體2之狀態。The stroller 1 of this embodiment is described using FIGS. 1 to 4 . The stroller 1 is foldable. That is, the stroller 1 is switchable between the unfolded state shown in FIGS. 1 to 3 and the folded state shown in FIG. 4 . The unfolded state means a state in which the stroller body 2 is expanded (unfolded) so that a baby can sit in the stroller 1 . The folded state means a state in which the stroller body 2 is folded in order to compactly store the stroller 1 .

於本說明書中，相對於嬰兒車1之「前」、「後」、「左」、「右」、「上」、「下」、「前後方向」、「左右方向」、及「上下方向」之用語，於無特別說明之情形時，意指以乘坐展開狀態之嬰兒車1之嬰幼兒為基準之「前」、「後」、「左」、「右」、「上」、「下」、「前後方向」、「左右方向」、及「上下方向」。於嬰兒車1之接地面為水平面之情形時，「前後方向」為平行於接地面之嬰兒車1之進退方向。又，「上下方向」為正交於前後方向且正交於接地面之方向。又，「左右方向」為正交於前後方向及上下方向兩者之方向。In this specification, the terms "front", "rear", "left", "right", "up", "down", "front-rear direction", "left-right direction", and "up-down direction" with respect to the stroller 1, unless otherwise specified, mean the "front", "rear", "left", "right", "up", "down", "front-rear direction", "left-right direction", and "up-down direction" based on the infant sitting in the unfolded stroller 1. When the ground contact surface of the stroller 1 is a horizontal plane, the "front-rear direction" is the forward and backward direction of the stroller 1 parallel to the ground contact surface. In addition, the "up-down direction" is a direction perpendicular to the front-rear direction and perpendicular to the ground contact surface. In addition, the "left-right direction" is a direction perpendicular to both the front-rear direction and the up-down direction.

於圖1～圖4中，將「前後方向」表示為X軸方向，將「左右方向」表示為Y軸方向，將「上下方向」表示為Z軸方向。X軸方向之負方向側相當於「前」，X軸方向之正方向側相當於「後」。又，Y軸方向之正方向相當於「右」，Y軸方向之負方向側相當於「左」。又，Z軸方向之正方向相當於「上」，Z軸方向之負方向相當於「下」。另，於「左右方向」上，將接近乘坐於嬰兒車1之嬰幼兒(嬰兒車1之左右方向之中心)之側稱為內側，將離開嬰幼兒之側稱為外側。In FIGS. 1 to 4 , the “front-rear direction” is represented as the X-axis direction, the “left-right direction” is represented as the Y-axis direction, and the “up-down direction” is represented as the Z-axis direction. The negative direction of the X-axis direction is equivalent to the “front”, and the positive direction of the X-axis direction is equivalent to the “back”. Furthermore, the positive direction of the Y-axis direction is equivalent to the “right”, and the negative direction of the Y-axis direction is equivalent to the “left”. Furthermore, the positive direction of the Z-axis direction is equivalent to the “up”, and the negative direction of the Z-axis direction is equivalent to the “down”. In addition, in the “left-right direction”, the side closer to the infant riding in the stroller 1 (the center of the stroller 1 in the left-right direction) is called the inner side, and the side away from the infant is called the outer side.

如圖1及圖2所示，嬰兒車1具備嬰兒車本體2、與安裝於嬰兒車本體2之座椅3。嬰兒車本體2具有本體框架10、連接於本體框架10之把手20及座椅支持部30。圖1及圖2均為顯示展開狀態之嬰兒車1之立體圖。圖1係顯示座椅3安裝於嬰兒車本體2之狀態之圖，圖2係顯示自嬰兒車本體2拆下座椅3之圖。As shown in Fig. 1 and Fig. 2, the baby stroller 1 has a baby stroller body 2 and a seat 3 mounted on the baby stroller body 2. The baby stroller body 2 has a body frame 10, a handle 20 connected to the body frame 10, and a seat support portion 30. Fig. 1 and Fig. 2 are both three-dimensional views showing the baby stroller 1 in an unfolded state. Fig. 1 is a view showing a state where the seat 3 is mounted on the baby stroller body 2, and Fig. 2 is a view showing a state where the seat 3 is removed from the baby stroller body 2.

本體框架10具有分別設置於左右兩側之一對前腳11、一對後腳12及一對扶手13。各前腳11之上端部可旋動地連接於扶手13之前端部，該扶手13配置於與各前腳11對應之側(左側或右側)。同樣，各後腳12之上端部可旋動地連接於扶手13之前端部，該扶手13配置於與各後腳12對應之側(左側或右側)。各扶手13之後端部經由連桿構件14及旋動托架15連接於後腳12之中間部分，該後腳12配置於與各扶手13對應之側(左側或右側)。於連桿構件14之上端部設置有用於連結設置於後述之側壁部80之連結構件101之突起部14a。突起部14a形成為與連桿構件14平行向上方延伸之銷狀。The main body frame 10 has a pair of front legs 11, a pair of rear legs 12 and a pair of armrests 13 respectively arranged on the left and right sides. The upper end of each front leg 11 is rotatably connected to the front end of the armrest 13, and the armrest 13 is arranged on the side corresponding to each front leg 11 (left side or right side). Similarly, the upper end of each rear leg 12 is rotatably connected to the front end of the armrest 13, and the armrest 13 is arranged on the side corresponding to each rear leg 12 (left side or right side). The rear end of each armrest 13 is connected to the middle part of the rear leg 12 through a connecting rod member 14 and a rotating bracket 15, and the rear leg 12 is arranged on the side corresponding to each armrest 13 (left side or right side). A protrusion 14a for connecting to a connection member 101 provided on a side wall portion 80 described later is provided on the upper end portion of the link member 14. The protrusion 14a is formed in a pin shape extending upward in parallel with the link member 14.

把手20相對於如上述般構成之本體框架10可擺動地連接。如圖1及圖2所示，把手20形成為U字狀。於圖1～圖3所示之背面推動狀態(即，操作者(保護者)自乘坐於嬰兒車1之嬰幼兒之背面側持握把手20而操縱嬰兒車1之狀態)下，把手20之兩端之各部分相對於與各部分對應之側(左側或右側)之連桿構件14，以維持與連桿構件14平行之狀態之方式連結。另，把手20亦可構成為以把手20之手持部分移動至乘坐於嬰兒車1之嬰幼兒之前方之方式，可相對於本體框架10向圖3中之逆時針擺動。於該情形時，操作者可自與嬰幼兒面對面之前腳11側之位置持握把手20而操縱嬰兒車。即，能以嬰兒車1之後腳12側成為行進方向之前方之方式使嬰兒車1行走。於此種對面推動狀態下，把手20與連桿構件14非平行。於把手20之中央部，設置有用於進行切換展開狀態與折疊狀態之操作的操作部20a。藉由操作部20a之操作，可切換用於維持展開狀態或折疊狀態之鎖定狀態、與可切換展開狀態與折疊狀態之解鎖狀態。The handle 20 is connected to the main body frame 10 constructed as described above so as to be swingable. As shown in FIG. 1 and FIG. 2 , the handle 20 is formed in a U-shape. In the back-pushing state shown in FIG. 1 to FIG. 3 (i.e., the state in which the operator (protector) holds the handle 20 from the back side of the infant riding in the stroller 1 and operates the stroller 1), each part at both ends of the handle 20 is connected to the connecting rod member 14 on the side (left side or right side) corresponding to each part in a manner of maintaining a state parallel to the connecting rod member 14. In addition, the handle 20 can also be configured in a manner that the hand-held portion of the handle 20 is moved to the front of the infant riding in the stroller 1, and can be swung counterclockwise in FIG. 3 relative to the main body frame 10. In this case, the operator can operate the baby stroller by holding the handle 20 from the position on the front leg 11 side facing the baby. That is, the baby stroller 1 can be moved in a manner that the rear leg 12 side of the baby stroller 1 is in front of the travel direction. In this face-to-face pushing state, the handle 20 and the link member 14 are not parallel. An operating portion 20a for switching between the unfolded state and the folded state is provided at the center of the handle 20. By operating the operating portion 20a, a locking state for maintaining the unfolded state or the folded state and an unlocking state for switching between the unfolded state and the folded state can be switched.

嬰兒車1如下所述，藉由使各構成構件相互旋動，可自展開狀態(參照圖1～圖3)折疊為折疊狀態(參照圖4)。As described below, the stroller 1 can be folded from an unfolded state (see FIGS. 1 to 3 ) to a folded state (see FIG. 4 ) by rotating the components.

於本實施形態中作為一例，於要將圖1～圖3所示之展開狀態之嬰兒車1折疊時，一邊對操作部20a進行操作而設為解鎖狀態，一邊執行將把手20先向上方拉起、然後向下方下壓之操作。伴隨上述折疊操作，連桿構件14及旋動托架15離開後腳12，旋動托架15相對於後腳12向圖3及圖4中之順時針方向旋動。又，伴隨該動作，扶手13及座面支持框架31相對於連桿構件14，向圖3及圖4中之順時針方向旋動。另，因連桿構件14與把手20平行配置，故於圖3及圖4中隱藏於把手20之內側。In this embodiment, as an example, when the baby stroller 1 in the unfolded state shown in FIGS. 1 to 3 is to be folded, the operation portion 20a is operated to be set to the unlocked state, and the handle 20 is first pulled up and then pressed down. Accompanying the above folding operation, the link member 14 and the rotating bracket 15 leave the rear leg 12, and the rotating bracket 15 rotates clockwise in FIGS. 3 and 4 relative to the rear leg 12. In addition, accompanying this action, the armrest 13 and the seat support frame 31 rotate clockwise in FIGS. 3 and 4 relative to the link member 14. In addition, since the connecting rod member 14 is arranged in parallel with the handle 20 , it is hidden inside the handle 20 in FIGS. 3 and 4 .

如圖4所示，藉由上述折疊操作，可折疊嬰兒車1。如圖4所示，藉由將嬰兒車1設為折疊狀態，可使嬰兒車1之前後方向(X軸方向)之尺寸，較展開狀態下之嬰兒車1之前後方向(X軸方向)之尺寸更小型化。另，若要自折疊狀態展開嬰兒車1時，只要執行與上述折疊操作相反之操作即可。As shown in FIG4 , the stroller 1 can be folded by the folding operation. As shown in FIG4 , by setting the stroller 1 to the folded state, the size of the stroller 1 in the front-back direction (X-axis direction) can be made smaller than the size of the stroller 1 in the front-back direction (X-axis direction) in the unfolded state. In addition, when the stroller 1 is to be unfolded from the folded state, the operation opposite to the folding operation can be performed.

如圖2所示，座椅支持部30可斜躺地支持座椅3。座椅支持部30具有座面支持框架31、靠背支持框架32、基底座椅33、上方框架34及連結框架35。As shown in FIG2 , the seat support unit 30 supports the seat 3 in a reclining state. The seat support unit 30 includes a seat support frame 31 , a back support frame 32 , a base seat 33 , an upper frame 34 , and a connecting frame 35 .

座面支持框架31係位於乘坐於嬰兒車1之嬰幼兒之臀部下方之框架構件。靠背支持框架32係可擺動地連接於座面支持框架31、且位於乘坐於嬰兒車1之嬰幼兒之脊背之背後之部分。例如，座面支持框架31及靠背支持框架32各者可藉由整體具有U字狀之形狀之金屬製之管構成。The seat support frame 31 is a frame member located below the buttocks of the infant riding in the stroller 1. The backrest support frame 32 is a portion that is swingably connected to the seat support frame 31 and is located behind the back of the infant riding in the stroller 1. For example, each of the seat support frame 31 and the backrest support frame 32 can be formed of a metal pipe having a U-shape as a whole.

基底座椅33係張設於座面支持框架31及靠背支持框架32之布構件。基底座椅33具有支持後述之座椅3之座面部40之座面支持部331、與支持後述之座椅3之靠背部50之靠背支持部332。The base seat 33 is a fabric member stretched between the seat support frame 31 and the back support frame 32. The base seat 33 has a seat support portion 331 supporting a seat portion 40 of the seat 3 described later, and a back support portion 332 supporting a backrest portion 50 of the seat 3 described later.

上方框架34係於較靠背支持框架32更上方位置上，與靠背支持框架32大致平行地配置之U字狀之框架構件。連結框架35係連結靠背支持框架32與上方框架34之框架構件。The upper frame 34 is a U-shaped frame member disposed above the backrest support frame 32 and substantially parallel to the backrest support frame 32. The connecting frame 35 is a frame member connecting the backrest support frame 32 and the upper frame 34.

使用圖5及圖6，對安裝於座椅支持部30之座椅3進行說明。圖5係自正面4a側(嬰幼兒乘坐之側)觀察以座面部40與靠背部50平行之方式伸長之狀態之座椅3之俯視圖，圖6係自背面4b側觀察與圖5同樣狀態之座椅3之俯視圖。The seat 3 mounted on the seat support portion 30 is described using Fig. 5 and Fig. 6. Fig. 5 is a plan view of the seat 3 in a state where the seat portion 40 and the backrest portion 50 are extended in parallel, as viewed from the front 4a side (the side where the infant sits), and Fig. 6 is a plan view of the seat 3 in the same state as Fig. 5, as viewed from the back 4b side.

座椅3例如藉由具有緩衝性之素材構成，向落座於座椅3之正面4a側之嬰幼兒提供舒適之乘坐感覺。座椅3具有座面部40、靠背部50、包圍部60、罩部70及一對側壁部80。The seat 3 is made of a cushioning material, for example, to provide a comfortable riding feeling to an infant sitting on the front side 4a of the seat 3. The seat 3 includes a seat portion 40, a backrest portion 50, a surrounding portion 60, a cover portion 70, and a pair of side wall portions 80.

座面部40藉由受座面支持框架31保持之基底座椅33之座面支持部331支持，主要支持乘坐於嬰兒車1之嬰幼兒之臀部。The seat surface portion 40 is supported by the seat support portion 331 of the base seat 33 held by the seat support frame 31 , and mainly supports the buttocks of the infant sitting in the stroller 1 .

靠背部50連接於座面部40，位於座面部40之後方。靠背部50藉由受靠背支持框架32保持之基底座椅33之靠背支持部332支持，主要支持乘坐於嬰兒車1之嬰幼兒之脊背。The backrest portion 50 is connected to the seat portion 40 and is located behind the seat portion 40. The backrest portion 50 is supported by the backrest support portion 332 of the base seat 33 held by the backrest support frame 32, and mainly supports the back of the infant sitting in the stroller 1.

座面部40與靠背部50例如藉由相互縫製而連接。於該情形時，於座面部40與靠背部50之間，形成包含接縫之連接線L1。伴隨嬰兒車1之斜躺動作或折疊動作，座面部40及靠背部50相互接近。此時，座面部40及靠背部50以上述連接線L1為擺動軸線相對擺動。The seat surface 40 and the backrest 50 are connected by sewing each other, for example. In this case, a connection line L1 including a seam is formed between the seat surface 40 and the backrest 50. As the baby stroller 1 reclines or folds, the seat surface 40 and the backrest 50 approach each other. At this time, the seat surface 40 and the backrest 50 swing relative to each other with the connection line L1 as the swing axis.

包圍部60與連接於靠背部50之座面部40之緣部(連接線L1)以外之緣部連接。包圍部60係覆蓋並保護乘坐於嬰兒車1之嬰幼兒之上半身之上方及側方之部分。即，包圍部60包含作為保護嬰幼兒之頭部之頭枕發揮功能之部分。包圍部60例如縫製於靠背部50，靠背部50與包圍部60之連接部位藉由大致U字狀之縫製線區劃。The surrounding portion 60 is connected to the edge of the seat surface portion 40 connected to the backrest portion 50 (connection line L1) other than the edge. The surrounding portion 60 is a portion that covers and protects the upper and side parts of the upper body of the infant sitting in the baby carriage 1. That is, the surrounding portion 60 includes a portion that functions as a headrest to protect the head of the infant. The surrounding portion 60 is, for example, sewn to the backrest portion 50, and the connection portion between the backrest portion 50 and the surrounding portion 60 is divided by a substantially U-shaped sewing line.

罩部70係與連接於包圍部60之靠背部50之側之相反側之緣部連接，且以覆蓋包圍部60之背面側之罩狀設置之構件。如圖1所示，於座椅3安裝於座椅支持部30時，包圍部60與罩部70之連接部位以沿上方框架34(參照圖2)之方式配置，罩部70以覆蓋上方框架34及連結框架35之方式被覆。藉此，包圍部60被穩定地固定。The cover portion 70 is connected to the edge portion of the side opposite to the side of the backrest portion 50 connected to the surrounding portion 60, and is provided in a cover shape to cover the back side of the surrounding portion 60. As shown in FIG1, when the seat 3 is mounted on the seat support portion 30, the connecting portion between the surrounding portion 60 and the cover portion 70 is arranged along the upper frame 34 (see FIG2), and the cover portion 70 is covered to cover the upper frame 34 and the connecting frame 35. Thereby, the surrounding portion 60 is stably fixed.

一對側壁部80配置於左右方向(Y軸方向)之座面部40之兩側。側壁部80架設於座面部40與靠背部50。側壁部80構成為，於展開狀態(參照圖1)下，不直接受座椅支持部30支持，而維持相對於座面部40大致垂直立起之狀態。A pair of side walls 80 are disposed on both sides of the seat surface 40 in the left-right direction (Y-axis direction). The side walls 80 are mounted between the seat surface 40 and the backrest 50. The side walls 80 are configured to be not directly supported by the seat support 30 in the unfolded state (see FIG. 1 ), but to be substantially vertically erected relative to the seat surface 40.

於各側壁部80自座面部40及靠背部50離開之側之端部，設置有於展開狀態下朝向連桿構件14之突起部14a延伸之突出部85。於突出部85之背面4b設置有連結於突起部14a之連結構件101。作為一例，連結構件101係具有相對於突出部85固定之帶部101a、與設置於帶部101a之兩端之一對掛鉤101b(構成為彼此嵌合之掛鉤對)之掛鉤帶。藉由將帶部101a捲繞於突起部14a之側面，將一對掛鉤101b彼此(即，凹部與凸部彼此)相互扣住，如圖1所示，連結構件101相對於突起部14a固定。藉此，展開狀態下之側壁部80之立起姿勢穩定化。At the end of each side wall portion 80 away from the seat portion 40 and the backrest portion 50, a protrusion 85 is provided which extends toward the protrusion 14a of the link member 14 in the expanded state. A connecting member 101 connected to the protrusion 14a is provided on the back surface 4b of the protrusion 85. As an example, the connecting member 101 is a hook belt having a belt portion 101a fixed relative to the protrusion 85 and a pair of hooks 101b (constituting a pair of hooks that fit into each other) provided at both ends of the belt portion 101a. By wrapping the belt portion 101a around the side surface of the protrusion 14a, a pair of hooks 101b are interlocked with each other (i.e., the concave portion and the convex portion are interlocked with each other), as shown in Fig. 1, and the connecting member 101 is fixed relative to the protrusion 14a. Thereby, the standing posture of the side wall portion 80 in the unfolded state is stabilized.

可直接接觸乘坐於嬰兒車1之嬰幼兒之座面部40、靠背部50及包圍部60，例如可使用具有緩衝性之布材構成。作為此種布材之具體例，可舉出由2塊衣料夾著海綿等之材料而成之布材、包含具有緩衝性之衣料本身之布材等。又，因側壁部80中至少配置於左右方向之內側之部分亦可直接接觸嬰幼兒，故可由具有緩衝性之布材構成。The seat surface 40, the backrest 50 and the surrounding portion 60 that can directly contact the infant riding in the stroller 1 can be made of, for example, a fabric having a cushioning property. Specific examples of such a fabric include a fabric made of a sponge or the like sandwiched between two pieces of clothing, and a fabric that includes clothing itself having a cushioning property. In addition, since at least the portion of the side wall portion 80 disposed on the inner side in the left-right direction can also directly contact the infant, it can be made of a fabric having a cushioning property.

接著，對相對於座椅支持部30之座椅3之安裝構造之細節進行說明。如圖6所示，座面部40具有第1面扣件部91，該第1面扣件部91包含設置於背面4b(與座面支持部331對向之面)之一個以上之面扣件。於本實施形態中，第1面扣件部91僅包含1個面扣件911。靠背部50具有第2面扣件部92，該第2面扣件部92包含設置於背面4b(與靠背支持部332對向之面)之一個以上之面扣件。於本實施形態中，第2面扣件部92包含4個面扣件921～924。Next, the details of the mounting structure of the seat 3 relative to the seat support portion 30 are described. As shown in FIG. 6 , the seat portion 40 has a first surface fastener portion 91, and the first surface fastener portion 91 includes one or more surface fasteners provided on the back surface 4b (the surface opposite to the seat support portion 331). In the present embodiment, the first surface fastener portion 91 includes only one surface fastener 911. The backrest portion 50 has a second surface fastener portion 92, and the second surface fastener portion 92 includes one or more surface fasteners provided on the back surface 4b (the surface opposite to the backrest support portion 332). In the present embodiment, the second surface fastener portion 92 includes four surface fasteners 921 to 924.

面扣件911於較座面部40之前後方向(X軸方向)之中央部稍靠前方之位置上，形成為於左右方向(Y軸方向)延伸之橫長之矩形狀。The surface fastener 911 is formed in a horizontally long rectangular shape extending in the left-right direction (Y-axis direction) at a position slightly forward of the center portion of the seat surface portion 40 in the front-back direction (X-axis direction).

面扣件921～924配置於較靠背部50之上下方向(正交於連接線L1之方向)之中央部更上方之位置(於本實施形態中為靠背部50之上端部之附近)。面扣件921～924具有彼此大致同一之矩形狀，面扣件921～924各者之面積小於面扣件911之面積。The surface fasteners 921-924 are arranged at a position above the center of the backrest 50 in the up-down direction (direction perpendicular to the connection line L1) (in the present embodiment, near the upper end of the backrest 50). The surface fasteners 921-924 have substantially the same rectangular shape, and the area of each surface fastener 921-924 is smaller than the area of the surface fastener 911.

面扣件921、924配置於相對於沿靠背部50之上下方向之中心線相互對稱之位置。面扣件921、924沿靠背部50之左右方向(Y軸方向)之兩側緣部配置。面扣件921、924以面扣件921、924之長度方向與靠背部50之左右方向(Y軸方向)之兩側緣部大致平行之方式配置。The surface fasteners 921 and 924 are arranged at positions symmetrical to each other with respect to the center line along the vertical direction of the backrest 50. The surface fasteners 921 and 924 are arranged along the side edges of the backrest 50 in the left-right direction (Y-axis direction). The surface fasteners 921 and 924 are arranged in a manner that the length direction of the surface fasteners 921 and 924 is substantially parallel to the side edges of the backrest 50 in the left-right direction (Y-axis direction).

面扣件922、923配置於相對於沿靠背部50之上下方向之中心線相互對稱之位置。面扣件922、923沿靠背部50之上端之緣部51a配置。面扣件922、923以面扣件922、923之長度方向與緣部51a大致平行之方式配置。The surface fasteners 922 and 923 are arranged at positions symmetrical to each other with respect to the center line along the up-down direction of the backrest 50. The surface fasteners 922 and 923 are arranged along the edge 51a of the upper end of the backrest 50. The surface fasteners 922 and 923 are arranged in a manner that the length direction of the surface fasteners 922 and 923 is substantially parallel to the edge 51a.

如圖2所示，座面支持部331具有第3面扣件部93，該第3面扣件部93包含於與第1面扣件部91對應之位置上，以與第1面扣件部91對應之形狀設置之一個以上之面扣件。於本實施形態中，第3面扣件部93包含與第1面扣件部91所包含之面扣件911對應之面扣件931。於本實施形態中，面扣件931形成為與面扣件911相同之矩形狀，且於將座面部40相對於座面支持部331配置於適當位置之情形時，配置於與面扣件911重疊之位置。As shown in FIG. 2 , the seat support portion 331 has a third surface fastener portion 93, which includes one or more surface fasteners provided in a shape corresponding to the first surface fastener portion 91 at a position corresponding to the first surface fastener portion 91. In this embodiment, the third surface fastener portion 93 includes a surface fastener 931 corresponding to the surface fastener 911 included in the first surface fastener portion 91. In this embodiment, the surface fastener 931 is formed in the same rectangular shape as the surface fastener 911, and is arranged at a position overlapping with the surface fastener 911 when the seat surface portion 40 is arranged at an appropriate position relative to the seat support portion 331.

靠背支持部332具有第4面扣件部94，該第4面扣件部94包含於與第2面扣件部92對應之位置上，以與第2面扣件部92對應之形狀設置之一個以上之面扣件。於本實施形態中，第4面扣件部94包含與第2面扣件部92所包含之4個面扣件921～924各者對應之4個面扣件941～944。於本實施形態中，面扣件941～944形成為與面扣件921～924相同之矩形狀，且於將靠背部50相對於靠背支持部332配置於適當位置之情形時，配置於與面扣件921～924重疊之位置。The backrest support portion 332 has a fourth surface fastener portion 94, which includes one or more surface fasteners provided in a shape corresponding to the second surface fastener portion 92 at a position corresponding to the second surface fastener portion 92. In this embodiment, the fourth surface fastener portion 94 includes four surface fasteners 941 to 944 corresponding to the four surface fasteners 921 to 924 included in the second surface fastener portion 92. In this embodiment, the surface fasteners 941 to 944 are formed in the same rectangular shape as the surface fasteners 921 to 924, and are arranged at a position overlapping with the surface fasteners 921 to 924 when the backrest portion 50 is arranged at an appropriate position relative to the backrest support portion 332.

作為一例，設置於座椅3之面扣件(即，第1面扣件部91所包含之面扣件911及第2面扣件部92所包含之面扣件921～924)可構成為環部(所謂母部、凹面等)。另一方面，設置於座椅支持部30之面扣件(第3面扣件部93所包含之面扣件931及第4面扣件部94所包含之面扣件941～944)可構成為掛鉤部(所謂公部、凸面等)。藉此，於將座椅3配置於座椅支持部30上之情形時，相互對向之面扣件彼此(即，設置於座椅3之面扣件與設置於座椅支持部30之面扣件之組)相互扣合。For example, the surface fasteners provided on the seat 3 (i.e., the surface fasteners 911 included in the first surface fastener portion 91 and the surface fasteners 921 to 924 included in the second surface fastener portion 92) may be configured as a ring portion (so-called female portion, concave surface, etc.). On the other hand, the surface fasteners provided on the seat support portion 30 (the surface fasteners 931 included in the third surface fastener portion 93 and the surface fasteners 941 to 944 included in the fourth surface fastener portion 94) may be configured as a hook portion (so-called male portion, convex surface, etc.). Thus, when the seat 3 is arranged on the seat support portion 30, the surface fasteners facing each other (i.e., the combination of the surface fasteners provided on the seat 3 and the surface fasteners provided on the seat support portion 30) are engaged with each other.

於上述嬰兒車1中，座椅3之座面部40經由第1面扣件部91及第3面扣件部93，固定於座椅支持部30之座面支持部331，且座椅3之靠背部50經由第2面扣件部92及第4面扣件部94，固定於座椅支持部30之靠背支持部332。如此，藉由使用面扣件將座椅3之座面部40及靠背部50兩者固定於座椅支持部30，可相對於座椅支持部30平衡較佳且穩定地固定座椅3。又，可減少先前一般用於對嬰兒車本體2安裝座椅之掛鉤帶等之固定具(例如與上述連結構件101同樣之固定具)之數量。例如，先前，一般採用於座面部40及靠背部50各者至少設置一組(左右一對)掛鉤帶，並將該掛鉤帶安裝於基底座椅33之結構。於嬰兒車1中，藉由設置第1面扣件部91、第2面扣件部92、第3面扣件部93及第4面扣件部94，如上述般省略先前設置於座面部40及靠背部50各者之掛鉤帶。藉此，可謀求零件個數之削減引起之嬰兒車1之低成本化，且可將座椅3之裝卸操作簡單化。再者，使用者僅以將座椅3之座面部40及靠背部50按壓於座椅支持部30之對應位置，即可於座椅支持部30固定座椅3，僅以將座椅3自座椅支持部30拉離(拉開)，即可自座椅支持部30拆下座椅3。即，藉由使用面扣件作為用於將座椅3安裝於座椅支持部30之主要構件，可相對於座椅支持部30直觀且容易地拆下座椅3。因此，根據嬰兒車1，可提高座椅3之裝卸作業之便利性。In the above-mentioned baby stroller 1, the seat surface 40 of the seat 3 is fixed to the seat surface support portion 331 of the seat support portion 30 via the first surface fastener portion 91 and the third surface fastener portion 93, and the backrest portion 50 of the seat 3 is fixed to the backrest support portion 332 of the seat support portion 30 via the second surface fastener portion 92 and the fourth surface fastener portion 94. In this way, by fixing both the seat surface 40 and the backrest portion 50 of the seat 3 to the seat support portion 30 using the surface fasteners, the seat 3 can be fixed to the seat support portion 30 with good balance and stability. In addition, the number of fixing devices (such as the same fixing device as the above-mentioned connecting structure 101) that are generally used to install the seat on the baby stroller body 2 can be reduced. For example, in the past, at least one set (a pair of left and right) of hooks was generally provided on each of the seat surface 40 and the backrest 50, and the hooks were installed on the structure of the base seat 33. In the stroller 1, by providing the first surface fastener portion 91, the second surface fastener portion 92, the third surface fastener portion 93, and the fourth surface fastener portion 94, the hooks previously provided on each of the seat surface 40 and the backrest 50 are omitted as described above. In this way, the number of parts can be reduced to reduce the cost of the stroller 1, and the assembly and disassembly operation of the seat 3 can be simplified. Furthermore, the user can fix the seat 3 to the seat support portion 30 by simply pressing the seat surface portion 40 and the backrest portion 50 of the seat 3 to the corresponding positions of the seat support portion 30, and can remove the seat 3 from the seat support portion 30 by simply pulling the seat 3 away from the seat support portion 30. That is, by using the surface fastener as the main component for mounting the seat 3 to the seat support portion 30, the seat 3 can be intuitively and easily removed from the seat support portion 30. Therefore, according to the baby stroller 1, the convenience of the loading and unloading operation of the seat 3 can be improved.

第1面扣件部91所包含之一個以上之面扣件(於本實施形態中為面扣件911)，形成為左右方向(Y軸方向)之長度長於前後方向(X軸方向)之長度之形狀(於本實施形態中以矩形狀為例)。又，第3面扣件部93所包含之一個以上之面扣件(於本實施形態中為面扣件931)，具有與第1面扣件部91所包含之一個以上之面扣件(於本實施形態中為面扣件911)對應之形狀。如本實施形態般，通常，於座椅支持部30之座面支持部331之左右方向(Y軸方向)之兩側配置有嬰兒車本體2之框架(例如扶手13等)。相對於此，如圖2所示，於座面支持部331之前方未配置上述般之框架。因此，要將座椅3之座面部40固定(載置)於座面支持部331時，較少有座面部40之位置相對於座面支持部331於左右方向(Y軸方向)偏離之疑慮，但另一方面，會有座面部40之位置相對於座面支持部331於前後方向(X軸方向)偏離之疑慮。假設，若第1面扣件部91所包含之面扣件911或第3面扣件部93所包含之面扣件931形成為前後方向(X軸方向)之長度長於左右方向(Y軸方向)之長度之形狀，則即使座椅3之座面部40之位置相對於座面支持部331之於前後方向(X軸方向)若干偏離，第1面扣件部91(面扣件911)仍會與第3面扣件部93(面扣件931)接觸而相互固定。相對於此，藉由將第1面扣件部91及第3面扣件部93所包含之面扣件911、931形成為左右方向(Y軸方向)之長度長於前後方向(X軸方向)之長度之形狀，當座面部40相對於座面支持部331於前後方向(X軸方向)偏離時，第1面扣件部91與第3面扣件部93不易相互接觸。其結果，可抑制座面部40在相對於座面支持部331於前後方向(X軸方向)偏離之狀態下被固定於座面支持部331。The one or more surface fasteners (the surface fasteners 911 in the present embodiment) included in the first surface fastener portion 91 are formed into a shape (a rectangular shape is used as an example in the present embodiment) whose length in the left-right direction (Y-axis direction) is longer than that in the front-back direction (X-axis direction). Furthermore, the one or more surface fasteners (the surface fasteners 931 in the present embodiment) included in the third surface fastener portion 93 have a shape corresponding to the one or more surface fasteners (the surface fasteners 911 in the present embodiment) included in the first surface fastener portion 91. As in the present embodiment, usually, the frame of the stroller body 2 (such as the armrests 13, etc.) is arranged on both sides of the seat support portion 331 of the seat support portion 30 in the left-right direction (Y-axis direction). In contrast, as shown in FIG. 2 , the above-mentioned frame is not arranged in front of the seat support portion 331. Therefore, when the seat portion 40 of the chair 3 is fixed (mounted) on the seat support portion 331, there is less concern that the position of the seat portion 40 deviates in the left-right direction (Y-axis direction) relative to the seat support portion 331. On the other hand, there is a concern that the position of the seat portion 40 deviates in the front-rear direction (X-axis direction) relative to the seat support portion 331. Assuming that the surface fastener 911 included in the first surface fastener portion 91 or the surface fastener 931 included in the third surface fastener portion 93 is formed into a shape in which the length in the front-to-back direction (X-axis direction) is longer than the length in the left-to-right direction (Y-axis direction), then even if the position of the seat portion 40 of the seat 3 is slightly deviated relative to the seat support portion 331 in the front-to-back direction (X-axis direction), the first surface fastener portion 91 (surface fastener 911) will still be in contact with the third surface fastener portion 93 (surface fastener 931) and fixed to each other. In contrast, by forming the surface fasteners 911 and 931 included in the first surface fastener portion 91 and the third surface fastener portion 93 into a shape in which the length in the left-right direction (Y-axis direction) is longer than the length in the front-back direction (X-axis direction), when the seat surface portion 40 deviates in the front-back direction (X-axis direction) relative to the seat surface support portion 331, the first surface fastener portion 91 and the third surface fastener portion 93 are less likely to contact each other. As a result, it is possible to prevent the seat surface portion 40 from being fixed to the seat surface support portion 331 in a state in which it deviates in the front-back direction (X-axis direction) relative to the seat surface support portion 331.

座椅3具有連結構件102(參照圖6)，該連結構件102設置於連接座面部40與靠背部50之邊界部(連接線L1)之附近(於本實施形態中為連接線L1之左右方向(Y軸方向)之兩端部之附近)。又，嬰兒車本體2具有與連結構件102連結之框架構件(於本實施形態中為連桿構件14)。於本實施形態中，連結構件102具有與連結構件101同樣之構成。連結構件102係具有相對於座椅3之背面4b固定之帶部102a、與設置於帶部102a之兩端之一對掛鉤102b之掛鉤帶。藉由將帶部102a捲繞於連桿構件14之側面，將一對掛鉤102b彼此(即，凹部與凸部彼此)相互扣住，如圖1所示，連結構件102相對於連桿構件14固定。根據上述構成，可一邊藉由連結構件102將座椅3固定於座椅支持部30，一邊使座椅3之座面部40與靠背部50之間之邊界部(連接線L1)對準適當位置。藉此，例如，藉由以上述邊界部為擺動軸線而使座面部40擺動並按壓於座面支持部331，可相對於座面支持部331容易地將座面部40固定於適當位置(即，面扣件911與面扣件931恰好重疊之位置)。同樣，藉由以上述邊界部為擺動軸線而使靠背部50擺動並按壓於靠背支持部332，可相對於靠背支持部332容易地將靠背部50固定於適當位置(即，面扣件921～944與面扣件941～944恰好重疊之位置)。如此，因藉由連結構件102將座面部40與靠背部50之邊界位置對準適當位置，可容易地進行座面部40及靠背部50之對位，故可提高座椅3之安裝作業之便利性。又，藉由並用面扣件與連結構件102，可減少連結構件之個數、提高安裝作業之便利性，且可提高座椅3之穩定性。例如，藉由連結構件102，抑制座面部40與靠背部50之邊界相對於座椅支持部30於前後方向(X軸方向)偏離。藉此，防止因落座於座椅3之嬰幼兒之移動等而使座椅3整體於前後方向(X軸方向)大幅移動，且抑制座面部40或靠背部50相對於座椅支持部30之利用面扣件之固定被剝離。The seat 3 has a connecting member 102 (see FIG. 6 ), which is disposed near the boundary (connecting line L1) connecting the seat surface portion 40 and the backrest portion 50 (in the present embodiment, near both ends of the connecting line L1 in the left-right direction (Y-axis direction)). In addition, the stroller body 2 has a frame member (in the present embodiment, a connecting rod member 14) connected to the connecting member 102. In the present embodiment, the connecting member 102 has the same structure as the connecting member 101. The connecting member 102 is a hook belt having a belt portion 102a fixed relative to the back surface 4b of the seat 3 and a hook 102b disposed at one of the two ends of the belt portion 102a. By winding the belt portion 102a around the side surface of the link member 14 and interlocking the pair of hooks 102b (i.e., the concave portion and the convex portion) with each other, as shown in FIG1 , the connecting member 102 is fixed relative to the connecting member 14. According to the above configuration, the seat 3 can be fixed to the seat support portion 30 by the connecting member 102 while the boundary portion (connection line L1) between the seat surface portion 40 and the backrest portion 50 of the seat 3 is aligned at an appropriate position. Thus, for example, by swinging the seat surface portion 40 with the boundary portion as the swing axis and pressing it against the seat surface support portion 331, the seat surface portion 40 can be easily fixed at an appropriate position relative to the seat surface support portion 331 (i.e., a position where the surface fastener 911 and the surface fastener 931 are exactly overlapped). Similarly, by swinging the backrest 50 with the above-mentioned boundary as the swing axis and pressing it against the backrest support 332, the backrest 50 can be easily fixed at an appropriate position relative to the backrest support 332 (i.e., the position where the surface fasteners 921-944 and the surface fasteners 941-944 just overlap). In this way, since the boundary position of the seat surface 40 and the backrest 50 is aligned at an appropriate position by the connecting structure 102, the seat surface 40 and the backrest 50 can be easily aligned, so the convenience of the installation operation of the seat 3 can be improved. In addition, by using the surface fastener and the connecting structure 102 together, the number of connecting structures can be reduced, the convenience of the installation operation can be improved, and the stability of the seat 3 can be improved. For example, the boundary between the seat portion 40 and the backrest portion 50 is prevented from deviating in the front-back direction (X-axis direction) relative to the seat support portion 30 by the connecting member 102. This prevents the entire seat 3 from moving in the front-back direction (X-axis direction) due to the movement of an infant or young child sitting on the seat 3, and prevents the seat portion 40 or the backrest portion 50 from being removed from the seat support portion 30 by the surface fastener.

第2面扣件部92包含複數個面扣件(於本實施形態中為4個面扣件921～924)。又，第4面扣件部94包含與第2面扣件部92所包含之複數個面扣件921～924對應之複數個面扣件941～944。根據上述構成，可將為了相對於靠背支持部332以足夠之強度固定靠背部50而需要之各個面扣件921～924及941～944之面積小型化。藉此，因可藉由設置大型之面扣件而避免阻礙靠背部50之指定部位之通氣性，故可維持乘坐於嬰兒車1之嬰幼兒之舒適性。The second surface fastener portion 92 includes a plurality of surface fasteners (four surface fasteners 921 to 924 in the present embodiment). Furthermore, the fourth surface fastener portion 94 includes a plurality of surface fasteners 941 to 944 corresponding to the plurality of surface fasteners 921 to 924 included in the second surface fastener portion 92. According to the above-mentioned structure, the area of each surface fastener 921 to 924 and 941 to 944 required to fix the backrest portion 50 with sufficient strength relative to the backrest support portion 332 can be miniaturized. In this way, since the ventilation of a designated portion of the backrest portion 50 can be avoided from being obstructed by providing a large surface fastener, the comfort of the infant riding in the stroller 1 can be maintained.

第2面扣件部92設置於沿靠背部50之緣部51之位置。對應於此，第4面扣件部94設置於沿靠背支持部332之緣部之位置。根據上述構成，因藉由在與靠背部50之中央部重疊之區域未設置面扣件，而可確保靠背部50中主要接觸嬰幼兒之脊背之部分之通氣性，故可維持乘坐於嬰兒車1之嬰幼兒之舒適性。例如，於以網格布料等之通氣性良好之素材形成靠背部50之情形時，於與靠背部50之中央部重疊之區域設置之面扣件會堵塞網格布料之間隙，因此，可防止阻礙主要接觸嬰幼兒之脊背之部分之通氣性。The second surface fastener portion 92 is disposed along the edge 51 of the backrest portion 50. Correspondingly, the fourth surface fastener portion 94 is disposed along the edge of the backrest support portion 332. According to the above configuration, since the surface fastener is not disposed in the area overlapping with the central portion of the backrest portion 50, the ventilation of the portion of the backrest portion 50 that mainly contacts the back of the infant can be ensured, thereby maintaining the comfort of the infant riding in the stroller 1. For example, when the backrest portion 50 is formed of a material with good ventilation such as a mesh fabric, the surface fastener disposed in the area overlapping with the central portion of the backrest portion 50 will block the gap of the mesh fabric, thereby preventing the ventilation of the portion that mainly contacts the back of the infant from being obstructed.

第2面扣件部92包含面扣件(於本實施形態中為面扣件922、923)，該面扣件至少沿靠背部50中連接於座面部40之側之相反側之緣部51a設置。根據上述構成，藉由於儘量遠離座面部40之位置將靠背部50固定於靠背支持部332，可相對於靠背支持部332穩定地支持靠背部50。The second surface fastener portion 92 includes surface fasteners (surface fasteners 922, 923 in this embodiment) provided along at least the edge portion 51a of the backrest portion 50 on the opposite side of the side connected to the seat surface portion 40. According to the above configuration, the backrest portion 50 is fixed to the backrest support portion 332 at a position as far away from the seat surface portion 40 as possible, so that the backrest portion 50 can be stably supported relative to the backrest support portion 332.

座椅支持部30具有支持框架(於本實施形態中為靠背支持框架32)，該支持框架以沿靠背部50之緣部51中連接於座面部40之第1部分51b(即沿連接線L1之部分)以外之第2部分51c(於圖6中，緣部51中除第1部分51b外之逆U字狀之部分(包含緣部51a))之方式形成。又，於靠背部50之第2部分51c設置抑制緣部51之變形之抑制構件103。根據上述構成，藉由以靠背部50之緣部51之第2部分51c沿靠背支持框架32之方式將靠背部50按壓於靠背支持部332之操作，可使靠背部50相對於靠背支持部332容易且適當地對位。又，因藉由設置於第2部分51c之抑制構件103抑制第2部分51c之變形，故可容易地進行上述操作，且可提高靠背部50之支持穩定性。The seat support portion 30 has a support frame (a backrest support frame 32 in the present embodiment) formed along a second portion 51c (in FIG. 6 , an inverted U-shaped portion (including the edge 51a) of the edge 51 of the backrest portion 50 other than the first portion 51b (i.e., the portion along the connection line L1) connected to the seat surface portion 40. In addition, a suppressing member 103 for suppressing deformation of the edge 51 is provided at the second portion 51c of the backrest portion 50. According to the above-mentioned structure, by pressing the backrest portion 50 against the backrest support portion 332 in a manner that the second portion 51c of the edge 51 of the backrest portion 50 is along the backrest support frame 32, the backrest portion 50 can be easily and appropriately positioned relative to the backrest support portion 332. Furthermore, since the deformation of the second portion 51c is suppressed by the suppressing member 103 provided in the second portion 51c, the above-mentioned operation can be easily performed, and the support stability of the backrest portion 50 can be improved.

於本實施形態中，抑制構件103藉由對第2部分51c進行包邊之被覆構件形成。根據上述構成，藉由沿第2部分51c進行包邊之被覆構件(例如包邊帶等)，可容易且確實地設置抑制構件103。又，因相對於靠背支持框架32沿靠背部50之部分之視認性及外觀藉由包邊而提高，故使用者藉由將包邊部(被覆構件)設為記號，可相對於座椅支持部30容易地將靠背部50配置於適當位置。另，於本實施形態中，如圖6所示，抑制構件103延伸至與靠背部50之緣部51連續之座面部40之緣部為止，亦形成於座面部40與側壁部80之間。In the present embodiment, the restraining member 103 is formed by a covering member that is hemmed along the second portion 51c. According to the above configuration, the restraining member 103 can be easily and reliably set by the covering member (e.g., hemming tape) that is hemmed along the second portion 51c. In addition, since the visibility and appearance of the portion along the backrest portion 50 relative to the backrest support frame 32 are improved by the hemming, the user can easily arrange the backrest portion 50 at an appropriate position relative to the seat support portion 30 by setting the hemming portion (covering member) as a mark. In addition, in the present embodiment, as shown in FIG. 6, the restraining member 103 extends to the edge of the seat surface portion 40 that is continuous with the edge 51 of the backrest portion 50, and is also formed between the seat surface portion 40 and the side wall portion 80.

以上，雖對本揭示之一實施形態進行了說明，但本揭示並未限定於上述之實施形態。對於各構成之材料及形狀，並未限定於上述之材料及形狀，可採用各種材料及形狀。Although one embodiment of the present disclosure has been described above, the present disclosure is not limited to the above embodiment. The materials and shapes of each component are not limited to the above materials and shapes, and various materials and shapes can be used.

例如，上述實施形態之嬰兒車1之嬰兒車本體2之構成僅為一例，亦可具有與上述實施形態不同之框架構造。又，座椅3只要至少具有座面部40及靠背部50即可，亦可省略其他構成(例如罩部70)。For example, the structure of the stroller body 2 of the above-mentioned embodiment is only an example, and the stroller body 2 may have a frame structure different from that of the above-mentioned embodiment. In addition, the seat 3 only needs to have at least the seat surface 40 and the backrest 50, and other structures (such as the cover 70) may be omitted.
