Description

この発明は、例えば車両に用いる座席シートに関するものである。   The present invention relates to a seat for use in a vehicle, for example.

一般に、車両の通常の座席シートは、その尻置き部及び背凭れ部が、ウレタン発泡体よりなるクッション材により形成され、このクッション材が、ファブリック等の表皮材で覆われることによって形成されている。そして、このような表皮材とクッション材との組み合わせからなる座席シートの背凭れ部は、感触が柔らかく、背中を凭れかけた場合、心地良く体を受け止める。なお、ウレタン発泡体は、多数の連続孔を有するため、通気性を備えている。   In general, a normal seat of a vehicle is formed by forming a butt rest portion and a backrest portion with a cushion material made of urethane foam, and the cushion material is covered with a skin material such as a fabric. . And the backrest part of the seat which consists of a combination of such a skin material and a cushion material has a soft touch, and when a back is drowned, it receives a body comfortably. In addition, since a urethane foam has many continuous holes, it has air permeability.

そして、前述の座席シートでは、ゆっくりと背凭れ部に凭れかかった場合には、クッション材が同様にゆっくりと圧縮変形されるため、クッション材の内部の空気が連通孔から円滑に排出され、適度なクッション性が得られる。しかしながら、前述の座席シートでは、勢いよく背凭れ部に凭れかかった場合には、クッション材に対して急激な圧縮力が加わる。このとき、該クッション材の連通孔は小さいので、クッション材の内部の空気が円滑に排出されない。このため、クッション材の圧縮変形が妨げられて、適度なクッション性を得ることができず、不快感を覚えることがあった。   And in the above-mentioned seat, when the seat is slowly sunk, the cushion material is similarly slowly compressed and deformed, so that the air inside the cushion material is smoothly discharged from the communication hole, Cushioning properties can be obtained. However, in the above-described seat seat, when the seat seat is vigorously leaned, a sudden compressive force is applied to the cushion material. At this time, since the communication hole of the cushion material is small, the air inside the cushion material is not smoothly discharged. For this reason, the compression deformation of the cushion material is hindered, so that an appropriate cushioning property cannot be obtained, and an uncomfortable feeling may be felt.

また、従来、図１２に示すように、座席シート１００の背凭れ部１０１として、表面が凹凸状をなしているクッション材１０２を表皮材１０３で覆うことによって形成されたものが知られている。この座席シート１００では、クッション材１０２の表面の凸部が変形することによって良好なクッション性を確保できるように見えるが、表面の凸部の頂面が半球状をなして平坦ではないため、勢いよく背凭れ部１０１に凭れかかった場合には、同凸部が潰れて空気の排出が円滑に行われない前述した状態になり、不快感を解決することができなかった。   Conventionally, as shown in FIG. 12, a backrest portion 101 of the seat 100 is formed by covering a cushion material 102 having an uneven surface with a skin material 103. In this seat sheet 100, it seems that a good cushioning property can be ensured by the deformation of the convex portion on the surface of the cushion material 102, but the top surface of the convex portion on the surface is hemispherical and not flat. When the backrest 101 is often drowned, the convex portion is crushed and the air is not smoothly discharged. Thus, the uncomfortable feeling cannot be solved.

この発明は、このような従来の技術に存在する問題点に着目してなされたものである。その目的は、勢いよく着座しても、快適なクッション性を得ることができる座席シートを提供することにある。   The present invention has been made paying attention to such problems existing in the prior art. An object of the present invention is to provide a seat that can provide comfortable cushioning even when seated vigorously.

上記目的を達成するために、請求項１の発明においては、背凭れ部を備え、発泡弾性材よりなるクッション材を表皮材で覆うことによって形成された座席シートにおいて、
前記背凭れ部のクッション材には、着座時に該クッション材が圧縮変形される際に、クッション材の内部の空気を排出するための複数の溝が平行に配列されており、各溝間の凸部の頂面が平坦になるように形成され、前記複数の溝は、前記背凭れ部の下部から上部に向かって段階的にその容積が大きくなるように形成されていることを要旨とするものである。 In order to achieve the above object, in the invention of claim 1, in a seat seat provided with a backrest portion and formed by covering a cushion material made of foamed elastic material with a skin material,
In the cushion material of the backrest, a plurality of grooves for discharging air inside the cushion material when the cushion material is compressed and deformed when seated are arranged in parallel. The top surface of the portion is formed to be flat, and the plurality of grooves are formed so that the volume thereof is gradually increased from the lower portion to the upper portion of the backrest portion. It is.

従って、座席シートに勢いよく着座した場合に、クッション材に対して急激な圧縮力が加わっても、溝間の凸部の頂面が平坦であるため、その凸部は全体的に圧縮されるものの、溝が塞がれることはなく、溝を介してクッション材の内部の空気が円滑に排出される。したがって、クッション材が適度に圧縮変形され、適度なクッション性を得ることができる。   Therefore, when the seat is vigorously seated, even if a sudden compression force is applied to the cushion material, the top surface of the convex portion between the grooves is flat, so that the convex portion is compressed as a whole. However, the groove is not blocked, and the air inside the cushion material is smoothly discharged through the groove. Therefore, the cushion material is appropriately compressed and deformed, and an appropriate cushioning property can be obtained.

また、背凭れ部のクッション材において、勢いよく背凭れ部に凭れかかった時に、大きな圧縮力が加わる背凭れ部の上部から下部に移るにつれて溝の容積が段階的に小さくなるように構成することで、クッション材の内部の空気を、クッション材に加わる圧縮力の大きさに応じて好適に排出させることができる。このため、クッション材のクッション性を向上させることができる。 In addition , in the cushion material of the backrest part, when the backrest part is vigorously strung, the volume of the groove is gradually reduced as it moves from the upper part to the lower part of the backrest part where a large compressive force is applied. Thus, the air inside the cushion material can be suitably discharged according to the magnitude of the compressive force applied to the cushion material. For this reason, the cushioning property of the cushioning material can be improved.

請求項２に記載の発明においては、請求項１において、前記複数の溝は、前記背凭れ部の幅方向における中央部から両端部に向かってその深さが浅くなるように形成されていることを要旨とするものである。 According to a second aspect of the present invention, in the first aspect , the plurality of grooves are formed so that the depth thereof decreases from the central portion in the width direction of the backrest portion toward both end portions. Is a summary.

従って、背凭れ部のクッション材において、勢いよく背凭れ部に凭れかかった時に、大きな圧縮力が加わる背凭れ部の幅方向における中央部から両端部に移るにつれて溝の深さが段階的に浅くなるように構成することで、クッション材の内部の空気を、クッション材に加わる圧縮力の大きさに応じて好適に排出させることができる。このため、クッション材のクッション性を向上させることができる。   Therefore, in the cushion material of the backrest part, when the backrest part is drooped vigorously, the depth of the groove gradually decreases as it moves from the center part to the both end parts in the width direction of the backrest part where a large compressive force is applied. By comprising so, the air inside a cushion material can be suitably discharged according to the magnitude | size of the compression force added to a cushion material. For this reason, the cushioning property of the cushioning material can be improved.

請求項３に記載の発明においては、請求項１又は請求項２において、前記複数の溝は、溝の開口側よりも溝の底部側の方が幅広になるように形成されていることを要旨とするものである。 According to a third aspect of the present invention, in the first or second aspect , the plurality of grooves are formed such that the bottom side of the groove is wider than the opening side of the groove. It is what.

従って、凸部の頂面の面積を広くすることが可能となり、溝が塞がれることなく、クッション材の内部の空気を円滑に排出できる。
請求項４に記載の発明においては、請求項１〜請求項３のいずれか一項において、前記クッション材には、複数の円錐台形状の突起が形成されており、これらの突起間に前記複数の溝が形成されていることを要旨とするものである。 Therefore, the area of the top surface of the convex portion can be increased, and the air inside the cushioning material can be smoothly discharged without blocking the groove.
According to a fourth aspect of the present invention, in the cushion material according to any one of the first to third aspects, a plurality of frustoconical protrusions are formed, and the plurality of frustoconical protrusions are formed between the protrusions. The gist is that the groove is formed.

従って、各突起の頂面が平坦であるので、着座時の不快感が抑制され、前記と同様に、クッション材の内部の空気を、溝を介して円滑に排出することができる。
請求項５に記載の発明においては、請求項１〜請求項４のいずれか一項において、前記複数の溝の深さは、前記クッション材の肉厚の３分の１以上で３分の２以下であることを要旨とするものである。 Therefore, since the top surface of each protrusion is flat, uncomfortable feeling at the time of sitting is suppressed, and the air inside the cushion material can be smoothly discharged through the groove as described above.
According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the depth of the plurality of grooves is one third or more of the thickness of the cushion material and two thirds. It is summarized as follows.

従って、前記複数の溝の深さと、溝底部とクッション材の裏面との間の厚さを充分に確保でき、クッション性とクッションの形状保持性との双方を得ることができて、座り心地の良い座席シートを実現できる。   Therefore, the depth of the plurality of grooves and the thickness between the groove bottom and the back surface of the cushioning material can be sufficiently secured, and both the cushioning property and the cushion shape retaining property can be obtained. A good seat can be realized.

以上のように、この発明においては、勢いよく着座しても、快適なクッション性が得られるという効果がある。   As described above, the present invention has an effect that a comfortable cushioning property can be obtained even when seated vigorously.

以下、本発明を具体化した実施形態を図１〜図４に基づいて説明する。
図１〜図３に示すように、この実施形態の車両用の座席シート１０は、尻置き部１３、背凭れ部１２及びヘッドレスト１１を備えている。背凭れ部１２は、フレーム１４に、発泡弾性材としてのウレタン発泡体よりなるクッション材１５を支持した状態で、該フレーム１４と該クッション材１５とを表皮材１８で覆うことによって構成されている。クッション材１５の表面には、該クッション材１５が圧縮変形される際に、クッション材１５の内部の空気を排出するための前面及び側端を開放した複数の溝１６が、背凭れ部１２の幅方向にほぼ直線状に延びるようにかつ互いに平行をなすように配列形成されている。このとき、前記各溝１６間の凸部２０は、それらの頂面が平坦になるように形成されている。なお、前記表皮材１８は、溝１６内に入り込んではいない。 DESCRIPTION OF EXEMPLARY EMBODIMENTS Embodiments of the invention will be described below with reference to FIGS.
As shown in FIGS. 1 to 3, the vehicle seat 10 according to this embodiment includes a butt rest portion 13, a backrest portion 12, and a headrest 11. The backrest 12 is configured by covering the frame 14 and the cushion material 15 with a skin material 18 in a state where the cushion material 15 made of urethane foam as a foamed elastic material is supported on the frame 14. . On the surface of the cushioning material 15, when the cushioning material 15 is compressed and deformed, a plurality of grooves 16 that open the front and side edges for discharging the air inside the cushioning material 15 are formed on the backrest 12. They are arranged so as to extend substantially linearly in the width direction and to be parallel to each other. At this time, the protrusions 20 between the grooves 16 are formed so that their top surfaces are flat. The skin material 18 does not enter the groove 16.

さらに、前記複数の溝１６の深さは、その溝１６の部分において前記クッション材１５の肉厚の３分の１以上で３分の２以下であることが好ましい。
そして、前記各溝１６は、背凭れ部１２の下部から上部に向かって段階的に深くなってその容積が大きくなるように形成されている。さらに、図１及び図４に示すように、前記各溝１６は、背凭れ部１２の幅方向における中央部から両端部に向かってその深さが浅くなるように形成されている。すなわち、前記各溝１６の溝底１６ａが、背凭れ部１２の幅方向における中央部から両端部に向かって直線的に上昇傾斜するように形成されている。 Further, the depth of the plurality of grooves 16 is preferably not less than one third and not more than two thirds of the thickness of the cushion material 15 in the groove 16 portion.
Each of the grooves 16 is formed so as to become deeper in a stepwise manner from the lower part to the upper part of the backrest part 12 and to increase its volume. Further, as shown in FIGS. 1 and 4, each of the grooves 16 is formed so that the depth thereof decreases from the center portion in the width direction of the backrest portion 12 toward both end portions. That is, the groove bottom 16 a of each groove 16 is formed so as to rise and incline linearly from the center portion in the width direction of the backrest portion 12 toward both end portions.

さて、図１〜図４に示すように、座席シート１０への着座時に、勢いよく背凭れ部１２に凭れかかると、背凭れ部１２の主として中央部には大きな圧縮力が加わる。この場合、溝１６間の凸部２０の頂面が平坦状をなしているため、前述した図１２の従来とは異なり、溝１６間の凸部２０の潰れが少なく、溝１６が塞がれることはない。このため、溝１６間の凸部２０の気泡に含まれた空気は溝１６内に排出される状態にある。従って、凸部２０の圧縮変形が阻害されることはなく、凸部２０は溝１６内に空気を排出しながら圧縮される。   As shown in FIG. 1 to FIG. 4, when the seat back 10 is seated on the seat seat 10, when the seat back 10 is drowned, a large compressive force is applied mainly to the central portion of the seat back portion 12. In this case, since the top surfaces of the protrusions 20 between the grooves 16 are flat, unlike the above-described conventional FIG. 12, the protrusions 20 between the grooves 16 are less crushed and the grooves 16 are blocked. There is nothing. For this reason, the air contained in the bubbles of the convex portion 20 between the grooves 16 is in a state of being discharged into the grooves 16. Therefore, the compressive deformation of the convex portion 20 is not hindered, and the convex portion 20 is compressed while discharging air into the groove 16.

このため、着座者が、勢いよく背凭れ部１２に凭れかかっても、クッション材１５により適度なクッション性が得られ、不快感なく快適に座席シート１０へ着座することができる。   For this reason, even if a seated person leans on the backrest part 12 vigorously, an appropriate cushioning property can be obtained by the cushion material 15, and the seated person can be seated comfortably without discomfort.

また、背凭れ部１２の下部から上部に移るにつれて複数の溝１６の容積が段階的に大きくなるように構成されている。このため、クッション材１５の内部の空気を、該クッション材１５にかかる圧縮力の大きさに応じて好適に排出させることができる。したがって、背凭れ部１２における圧縮力の大小の分布（上部側ほど大きな圧縮力が加えられる）に応じてクッション材１５が適度に圧縮変形され、該クッション材１５のクッション性を向上させることができる。   Moreover, it is comprised so that the volume of the some groove | channel 16 may become large in steps as it moves from the lower part of the backrest part 12 to the upper part. For this reason, the air inside the cushion material 15 can be suitably discharged according to the magnitude of the compressive force applied to the cushion material 15. Therefore, the cushioning material 15 is appropriately compressed and deformed according to the distribution of the compressive force in the backrest 12 (a larger compressive force is applied toward the upper side), and the cushioning property of the cushioning material 15 can be improved. .

加えて、背凭れ部１２に加わる圧縮力は、その幅方向中央部のほうが幅方向両端部より大きい。ここで、背凭れ部１２の幅方向における中央部から両端部に移るにつれて溝１６の深さが段階的に浅くなるように構成されている。このため、クッション材１５の内部の空気を、該クッション材１５に加わる圧縮力の大きさに応じて好適に排出させることができる。したがって、クッション材１５が適度に圧縮変形され、該クッション材１５のクッション性を向上させることができる。   In addition, the compressive force applied to the backrest 12 is greater at the widthwise center than at both widthwise ends. Here, it is comprised so that the depth of the groove | channel 16 may become shallow in steps as it moves to the both ends from the center part in the width direction of the backrest part 12. FIG. For this reason, the air inside the cushion material 15 can be suitably discharged according to the magnitude of the compressive force applied to the cushion material 15. Accordingly, the cushion material 15 is appropriately compressed and deformed, and the cushioning property of the cushion material 15 can be improved.

さらに、前記複数の溝１６の深さが、前記クッション材１５の肉厚の３分の１以上で３分の２以下であるため、前記溝１６の深さと、溝底部とクッション材１５の裏面との厚さを充分に確保することができる。このため、クッション性とクッションの形状保持性とを両立させることができる。   Furthermore, since the depth of the plurality of grooves 16 is not less than one third and not more than two thirds of the thickness of the cushion material 15, the depth of the groove 16, the groove bottom, and the back surface of the cushion material 15 A sufficient thickness can be secured. For this reason, it is possible to achieve both cushioning properties and cushion shape retaining properties.

なお、前記実施形態は以下のように変更してもよい。
・図５に示すように、クッション材１５の複数の溝を、複数の横溝１９及び縦溝２１よりなる格子状の溝にすること。この場合、縦溝２１は、図６に示すように、背凭れ部１２の下部から上部に向かって段階的に深くなってその容積が大きくなるように形成されている。 In addition, you may change the said embodiment as follows.
As shown in FIG. 5, the plurality of grooves of the cushion material 15 are made into a lattice-shaped groove including a plurality of horizontal grooves 19 and vertical grooves 21. In this case, as shown in FIG. 6, the longitudinal groove 21 is formed so as to become deeper stepwise from the lower part to the upper part of the backrest part 12 and to increase its volume.

・背凭れ部１２の各溝１６の底面形状を、図７に示すように、中央部ほど凹んだ略円弧形状にすること。
・図８（ａ）及び（ｂ）に示すように、クッション材１５の複数の溝１６の形状を、溝１６の前面開口側よりも溝１６の底部側の方が幅広になるように形成すること。 -The bottom face shape of each groove 16 of the backrest part 12 should be a substantially arc shape that is recessed toward the center as shown in FIG.
As shown in FIGS. 8A and 8B, the shape of the plurality of grooves 16 of the cushion material 15 is formed so that the bottom side of the grooves 16 is wider than the front opening side of the grooves 16. thing.

このように構成すれば、溝１６間の凸部２０の頂面の面積が広くなるため、座席シート１０に勢いよく着座した場合に、凸部２０の潰れが少なくなる。したがって、クッション性を向上させることができる。   If comprised in this way, since the area of the top face of the convex part 20 between the groove | channels 16 will become large, when seating on the seat sheet 10 vigorously, the collapse of the convex part 20 will decrease. Therefore, cushioning properties can be improved.

・図９に示すように、クッション材１５の表面に、複数の円錐台形状の突起１７を形成し、これらの突起１７間に複数の溝１６が形成されるようにすること。この場合、図１０に示すように、複数の溝１６は、背凭れ部１２の下部から上部に向かって深くなってその容積が大きくなっている。   As shown in FIG. 9, a plurality of frustoconical protrusions 17 are formed on the surface of the cushion material 15, and a plurality of grooves 16 are formed between these protrusions 17. In this case, as shown in FIG. 10, the plurality of grooves 16 become deeper from the lower part to the upper part of the backrest part 12 and the volume thereof is increased.

このように構成すれば、前記複数の溝１６間の頂面が平坦であるので、座席シート１０への着座時の不快感が抑制される。
・図１１に示すように、前記実施形態の背凭れ部１２のクッション材１５を、前記尻置き部１３にも用いること。この場合、容積の大きい溝１６が、座席シート１０の後部側に来るように、クッション材１５が尻置き部１３に配置される。 If comprised in this way, since the top surface between the said some groove | channels 16 is flat, the discomfort at the time of seating to the seat 10 is suppressed.
As shown in FIG. 11, the cushion material 15 of the backrest portion 12 of the embodiment is also used for the butt rest portion 13. In this case, the cushioning material 15 is disposed in the butt rest portion 13 so that the groove 16 having a large volume comes to the rear side of the seat 10.
