In addition, the same code | symbol is attached | subjected to the same element and the overlapping description is abbreviate | omitted. Further, the positional relationship such as up, down, left and right is based on the positional relationship shown in the drawings unless otherwise specified. Furthermore, the dimensional ratios in the drawings are not limited to the illustrated ratios. Moreover, the following embodiment is an illustration for explaining the present invention, and the present invention is not limited to this embodiment.
図１は車両用シート１の構成の一例を示す。例えば車両用シート１は、着座者が座る座部１０と、着座者が背中を凭れかける背凭れ部１１と、ヘッドレスト１２と、シートベルト１３等を有している。 FIG. 1 shows an example of the configuration of a vehicle seat 1. For example, the vehicle seat 1 includes a seat part 10 on which a seated person sits, a backrest part 11 on which the seated person sits down, a headrest 12, a seat belt 13, and the like.
背凭れ部１１は、ヘッドレスト１２の左右のいずれかの上面１１ａ（背凭れ部１１の肩部上面）に溝部２０を有している。図２に示すように溝部２０は、背凭れ部１１の前表面から後方に向けて形成されている。溝部２０は、略半円筒状に形成されている。背凭れ部１１の溝部２０のある部分以外の上面１１ａは、およそ平坦になっている。溝部２０の後方側には、開口部材３０が設けられている。すなわち、開口部材３０は、背凭れ部１１の背凭れ前表面よりも後方に後退した位置に設けられている。開口部材３０は、前面に開口３１を有し、シートベルト１３は背凭れ部１１の内部から開口３１を通じて前方に延出している。開口部材３０は、背凭れ部１１の上面において背凭れ部１１内に埋設されている。例えば開口部材３０は、背凭れ部１１の直方体状の外形内に収められ、開口部材３０の上面は、背凭れ部１１の上面１１ａとほぼ同一平面上に位置している。なお、本明細書において、「埋設」とは、開口部材３０の上面が、背凭れ部１１の他の部分の上面１１ａ（カバー４０のある状態）とほぼ同一平面上に位置しているか、背凭れ部１１の他の部分の上面１１ａより低い位置に位置していることをいう。 The backrest 11 has a groove 20 on either the left or right upper surface 11 a of the headrest 12 (the upper surface of the shoulder of the backrest 11). As shown in FIG. 2, the groove 20 is formed from the front surface of the backrest 11 toward the rear. The groove 20 is formed in a substantially semi-cylindrical shape. The upper surface 11a other than the portion where the groove portion 20 of the backrest portion 11 is provided is substantially flat. An opening member 30 is provided on the rear side of the groove 20. That is, the opening member 30 is provided at a position retracted rearward from the front surface of the backrest portion 11. The opening member 30 has an opening 31 on the front surface, and the seat belt 13 extends forward from the backrest portion 11 through the opening 31. The opening member 30 is embedded in the backrest portion 11 on the upper surface of the backrest portion 11. For example, the opening member 30 is housed in a rectangular parallelepiped outer shape of the backrest portion 11, and the upper surface of the opening member 30 is located on substantially the same plane as the upper surface 11 a of the backrest portion 11. In the present specification, “buried” means that the upper surface of the opening member 30 is located on substantially the same plane as the upper surface 11a of the other part of the backrest 11 (with the cover 40), or It means that it is located at a position lower than the upper surface 11a of the other part of the bent portion 11.
背凭れ部１１の表面は、カバー（トリムカバー）４０により覆われている。カバー４０は、例えば伸縮性、弾性のある素材、例えば化学繊維や合皮、本皮により形成されている。図３に示すように背凭れ部１１のカバー４０の内側には、クッションパッド４１が設けられている。クッションパッド４１は、例えばウレタンなどの素材により形成されている。背凭れ部１１の溝部２０と開口部材３０がある肩部では、クッションパッド４１が切り欠かれている。その背凭れ部１１の肩部には、背凭れ部１１の側壁の形状を保持する形状保持部材（壁部材）５０が設けられている。形状保持部材５０は、クッションパッド４１よりも外力に対して変形しにくい硬い材質（剛性の高い材質）、例えばポリプロピレン（ＰＰ）やポリアセタール（ＰＯＭ）などの樹脂により成形されている。 The surface of the backrest 11 is covered with a cover (trim cover) 40. The cover 40 is made of, for example, a stretchable or elastic material such as a chemical fiber, synthetic leather, or leather. As shown in FIG. 3, a cushion pad 41 is provided inside the cover 40 of the backrest 11. The cushion pad 41 is made of a material such as urethane. The cushion pad 41 is notched in the shoulder portion where the groove portion 20 of the backrest portion 11 and the opening member 30 are provided. A shape holding member (wall member) 50 that holds the shape of the side wall of the backrest 11 is provided on the shoulder of the backrest 11. The shape holding member 50 is formed of a hard material (a material having high rigidity) that is less likely to be deformed by an external force than the cushion pad 41, for example, a resin such as polypropylene (PP) or polyacetal (POM).
形状保持部材５０は、溝部２０及び開口部材３０のある部分の背凭れ部１１の側面１１ｂと後面１１ｃを覆うように形成されている。形状保持部材５０は、基部６０と、衝撃吸収部としての先端部６１を有している。先端部６１は、溝部２０の側面に位置し、背凭れ部１１の側壁の骨格の一部を形成している。基部６０は、先端部６１よりも後方側に位置し、背凭れ部１１の側壁の一部と後壁の骨格の一部を形成している。先端部６１は、基部６０よりも変形しやすい軟らかい材質（剛性の低い材質）により形成されている。よって、先端部６１は、形状保持部材５０としての機能を保持しつつ、衝撃吸収部としても機能する。例えば先端部６１には、発泡ＰＰ（ポリプロピレン）などの発泡樹脂が用いられ、基部６０には、ＰＰ（ポリプロピレン）などの樹脂が用いられる。なお、クッションパッド４１、先端部６１及び基部６０は、この順で硬さ（剛性）が大きくなる。 The shape holding member 50 is formed so as to cover the side surface 11b and the rear surface 11c of the backrest portion 11 where the groove portion 20 and the opening member 30 are located. The shape holding member 50 has a base portion 60 and a tip portion 61 as an impact absorbing portion. The tip portion 61 is located on the side surface of the groove portion 20 and forms a part of the skeleton of the side wall of the backrest portion 11. The base 60 is located on the rear side of the front end 61 and forms a part of the side wall of the backrest part 11 and a part of the skeleton of the rear wall. The tip portion 61 is formed of a soft material (a material having low rigidity) that is more easily deformed than the base portion 60. Therefore, the front end portion 61 functions as an impact absorbing portion while maintaining the function as the shape holding member 50. For example, a foamed resin such as foamed PP (polypropylene) is used for the tip portion 61, and a resin such as PP (polypropylene) is used for the base portion 60. The cushion pad 41, the distal end portion 61, and the base portion 60 increase in hardness (rigidity) in this order.
先端部６１と基部６０は、互いに嵌り合うように固定されている。例えば図４に示すように先端部６１は、背凭れ部１１の前後方向に沿って連続する凹凸状の下面６１ａを有している。基部６０は、先端部６１の凹凸状の下面６１ａに対応し、背凭れ部１１の前後方向に沿って連続する凹凸状の上面６０ａを有している。先端部６１を基部６０に嵌め込むことにより基部６０と先端部６１の前後方向の動きが規制される。 The distal end portion 61 and the base portion 60 are fixed so as to fit each other. For example, as shown in FIG. 4, the distal end portion 61 has an uneven lower surface 61 a that continues along the front-rear direction of the backrest portion 11. The base 60 corresponds to the concave and convex lower surface 61 a of the tip 61, and has a concave and convex upper surface 60 a that continues along the front-rear direction of the backrest 11. By fitting the distal end portion 61 into the base portion 60, the movement of the base portion 60 and the distal end portion 61 in the front-rear direction is restricted.
また、図５に示すように先端部６１の下面６１ａには、背凭れ部１１の左右方向に沿った凹部７０が形成されている。基部６０の上面６０ａには、先端部６１の下面６１ａの凹部７０に対応し、背凭れ部１１の左右方向に沿った凸部７１が形成されている。先端部６１を基部６０に嵌め込むことにより基部６０と先端部６１の左右方向の動きが規制される。 Further, as shown in FIG. 5, a concave portion 70 is formed on the lower surface 61 a of the tip portion 61 along the left-right direction of the backrest portion 11. On the upper surface 60 a of the base portion 60, a convex portion 71 is formed along the left-right direction of the backrest portion 11 corresponding to the concave portion 70 of the lower surface 61 a of the distal end portion 61. By fitting the distal end portion 61 into the base portion 60, the lateral movement of the base portion 60 and the distal end portion 61 is restricted.
図６に示すように背凭れ部１１は、背凭れ部１１の全体の骨格を構成する背凭れフレーム８０を有し、形状保持部材５０は、背凭れフレーム８０に取り付けられている。背凭れ部１１は、リクライニング機構を有し、後方に倒したり前方に立ち上げたりすることができる。 As shown in FIG. 6, the backrest portion 11 has a backrest frame 80 that constitutes the entire skeleton of the backrest portion 11, and the shape holding member 50 is attached to the backrest frame 80. The backrest 11 has a reclining mechanism, and can be tilted backward or raised forward.
図１に示すシートベルト１３は、背凭れ部１１内の下部に設けられたリトラクタ（図示せず）から上方に向けて延び、背凭れ部１１内の上部で前方に曲がり、開口部材３０の開口３１から外部に延出している。開口３１から延出したシートベルト１３は、座部１０の横に配置されたプリテンショナー９０に嵌め込まれて固定されている。またシートベルト１３には、タングプレート９１が取り付けられており、タングプレート９１を座部１０のバックル９２に係止することにより着座者はシートベルト１３を締めることができる。 The seat belt 13 shown in FIG. 1 extends upward from a retractor (not shown) provided at the lower part in the backrest part 11, bends forward at the upper part in the backrest part 11, and opens the opening member 30. It extends from 31 to the outside. The seat belt 13 extending from the opening 31 is fitted and fixed to a pretensioner 90 disposed beside the seat portion 10. Further, a tongue plate 91 is attached to the seat belt 13, and the seated person can fasten the seat belt 13 by locking the tongue plate 91 to the buckle 92 of the seat portion 10.
本実施の形態によれば、車両用シート１が、背凭れ部１１の肩部上面１１ａに溝部２０を有し、その溝部２０の後方側に、シートベルト１３が通る開口部材３０を設けているので、背凭れ部１１を立ち上げた際に開口部材３０が着座者に衝突することを抑制できる。 According to the present embodiment, the vehicle seat 1 has the groove portion 20 on the shoulder upper surface 11 a of the backrest portion 11, and the opening member 30 through which the seat belt 13 passes is provided on the rear side of the groove portion 20. Therefore, it is possible to suppress the opening member 30 from colliding with the seated person when the backrest 11 is raised.
開口部材３０が背凭れ部１１内に埋め込まれているので、背凭れ部１１を立ち上げた際に開口部材３０が着座者に衝突することをより十分に抑制できる。 Since the opening member 30 is embedded in the backrest part 11, when the backrest part 11 is started up, it can suppress more fully that the opening member 30 collides with a seated person.
背凭れ部１１のカバー４０の内側に、背凭れ部１１の側面側の溝部２０の側壁を形成し、当該側壁の形状を保持する形状保持部材５０が設けられている。これにより、溝部３０の側壁（背凭れ部１１の肩部）が肉薄となった場合でも、側壁の外形を保持することができる。この結果、例えばユーザーが溝部３０の側壁がある背凭れ部１１の肩部に手をかけ押したときに、背凭れ部１１の肩部が凹んで形が崩れることを抑制できる。また、形状保持部材５０は、背凭れ部１１の前面側に衝撃吸収部としての先端部６１を有しているので、着座者に対する背凭れ部１１の側壁の危害性をなくすことができる。 On the inner side of the cover 40 of the backrest portion 11, a side wall of the groove portion 20 on the side surface side of the backrest portion 11 is formed, and a shape holding member 50 that holds the shape of the side wall is provided. Thereby, even when the side wall (shoulder part of the backrest part 11) of the groove part 30 becomes thin, the external shape of a side wall can be hold | maintained. As a result, for example, when the user puts his hand on the shoulder portion of the backrest portion 11 where the side wall of the groove portion 30 is located, the shoulder portion of the backrest portion 11 can be prevented from being dented and deformed. Moreover, since the shape holding member 50 has the front-end | tip part 61 as an impact-absorbing part in the front side of the backrest part 11, the danger of the side wall of the backrest part 11 with respect to a seated person can be eliminated.
形状保持部材５０は、基部６０と先端部６１を有し、先端部６１が衝撃吸収部であり、先端部６１が、基部６０よりも軟らかくクッションパッド４１よりも硬いので、背凭れ部１１を立ち上げた際に形状保持部材５０がユーザーに当たっても危害性がない。また、ユーザーにより背凭れ部１１の肩部に荷重が付与されたときにも背凭れ部１１の側壁の外形を好適に保持することができる。 The shape holding member 50 has a base portion 60 and a tip portion 61, the tip portion 61 is an impact absorbing portion, and the tip portion 61 is softer than the base portion 60 and harder than the cushion pad 41. Even if the shape holding member 50 hits the user when it is raised, there is no danger. Moreover, the external shape of the side wall of the backrest part 11 can be suitably held even when a load is applied to the shoulder part of the backrest part 11 by the user.
先端部６１と基部６０が互いに嵌り合うように構成されているので、形状保持部材５０の組み付け作業を容易に行うことができる。 Since the front-end | tip part 61 and the base 60 are comprised so that it may mutually fit, the assembly | attachment operation | work of the shape holding member 50 can be performed easily.
先端部６１と基部６０は、互いに嵌り合うことにより背凭れ部１１の前後方向と左右方向の動きが規制されるように構成されている。これにより、先端部６１と基部６０の位置ずれを防止できる。 The distal end portion 61 and the base portion 60 are configured such that the movement of the backrest portion 11 in the front-rear direction and the left-right direction is restricted by fitting with each other. Thereby, the position shift of the front-end | tip part 61 and the base 60 can be prevented.
基部６０は、開口部材３０の後方側の後壁を形成しているので、開口部材３０の後方の背凭れ部１１の外形を保持することができる。 Since the base 60 forms the rear wall on the rear side of the opening member 30, the outer shape of the backrest portion 11 on the rear side of the opening member 30 can be maintained.
