Description

本発明は、パッドの裏面を支持する乗物シート用パッド支持装置に関する。   The present invention relates to a vehicle seat pad support device for supporting a back surface of a pad.

乗物シートは、パッドとパッドの裏面を支持するパッド支持装置を有する。パッド支持装置は、従来例えば、シートクッションの前後フレーム間を延出するＳばねと、前後フレーム間を延出するワイヤとを有する（特許文献１参照）。   The vehicle sheet includes a pad and a pad support device that supports the back surface of the pad. Conventionally, for example, the pad support device has an S spring extending between the front and rear frames of the seat cushion and a wire extending between the front and rear frames (see Patent Document 1).

実開平５−１３５０号公報Japanese Utility Model Publication No.5-1350

しかし従来のパッド支持装置は、Ｓばねとワイヤの関係が明確でない。そのためばねとワイヤがシートクッションの座り心地にどのように影響するのか良くわからない。そのため従来、シートの座り心地を向上し得るパッド支持装置が必要とされている。   However, in the conventional pad support device, the relationship between the S spring and the wire is not clear. For this reason, it is not clear how springs and wires affect the seat cushion comfort. Therefore, conventionally, there is a need for a pad support device that can improve the seating comfort of the seat.

前記課題を解決するために本発明は、各請求項に記載の通りの構成を備える乗物シート用パッド支持装置であることを特徴とする。一つの特徴によると本発明は、パッドの裏面を弾性的に支持しかつ両端部が乗物シートのフレームに取付けられるばね部材と、ばね部材よりも弾性変形し難い材料から形成されかつ両端部がフレームに取付けられるワイヤとを有する。ワイヤは、ばね部材よりもパッドの裏面から離れた位置で、かつパッドまたはばね部材の裏方向への弾性変形量を規制し得る位置に設置される。   In order to solve the above-mentioned problems, the present invention is a vehicle seat pad support device having a configuration as described in each claim. According to one aspect, the present invention includes a spring member that elastically supports the back surface of the pad and has both ends attached to the frame of the vehicle seat, a material that is less elastically deformed than the spring member, and both ends are frames. And a wire attached to the wire. The wire is disposed at a position farther from the back surface of the pad than the spring member and at a position where the amount of elastic deformation in the back direction of the pad or the spring member can be regulated.

したがってシートに着座した使用者の重みがパッドの表側に加わると、パッドとばね部材が弾性変形する。そのためパッドのみが弾性変形するシート等に比べて、シートの弾性変形量がばね部材の弾性変形によって多くなり、シートの座り心地が向上する。またパッド支持装置は、ばね部材よりも弾性変形し難いワイヤを有し、かつワイヤがばね部材よりもパッドの裏面から離れた位置に設置される。したがってパッドの表側から裏側に大きな力が加わると、パッドまたはばね部材がワイヤに当たる。これによりパッドまたはばね部材の裏側への弾性変形がワイヤによって規制され得る。かくしてシートが大きく変形し過ぎることで、使用者の姿勢が崩れることがワイヤによって抑制され得る。その結果、シートの座り心地が向上する。   Therefore, when the weight of the user seated on the seat is applied to the front side of the pad, the pad and the spring member are elastically deformed. Therefore, the amount of elastic deformation of the seat is increased by the elastic deformation of the spring member as compared with a seat or the like in which only the pad is elastically deformed, and the seating comfort of the seat is improved. The pad support device has a wire that is less elastically deformed than the spring member, and the wire is installed at a position farther from the back surface of the pad than the spring member. Therefore, when a large force is applied from the front side to the back side of the pad, the pad or the spring member hits the wire. Thereby, the elastic deformation to the back side of a pad or a spring member can be controlled by a wire. Thus, it is possible to suppress the posture of the user from being collapsed by the wire because the sheet is greatly deformed. As a result, seat comfort is improved.

乗物シートの斜視図である。It is a perspective view of a vehicle seat. 図１のII―II線断面矢視図である。It is the II-II sectional view taken on the line of FIG.

本発明の一つの実施の形態を図１，２にしたがって説明する。図１に示すように乗物シート１０は、自動車等の乗物の床面に装着されるシートであって、シートクッション１１とシートバック１２を有する。シートバック１２は、シートクッション１１の後部に角度調整可能に取付けられる。   One embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, a vehicle seat 10 is a seat that is mounted on a floor surface of a vehicle such as an automobile, and includes a seat cushion 11 and a seat back 12. The seat back 12 is attached to the rear portion of the seat cushion 11 so that the angle can be adjusted.

シートクッション１１は、図１，２に示すようにパッド１１ｂと、パッド１１ｂの表面を覆う表皮１１cと、フレーム１１ａを有する。フレーム１１ａは、シートクッション１１の左右縁に沿って前後方向に延出するサイドフレーム１３と、サイドフレーム１３の前部を連結する前フレーム１４と、サイドフレーム１３の後部を連結する後フレーム１５を有する。   As shown in FIGS. 1 and 2, the seat cushion 11 includes a pad 11b, a skin 11c that covers the surface of the pad 11b, and a frame 11a. The frame 11 a includes a side frame 13 that extends in the front-rear direction along the left and right edges of the seat cushion 11, a front frame 14 that connects the front part of the side frame 13, and a rear frame 15 that connects the rear part of the side frame 13. Have.

前フレーム１４には、図１に示すように前支持部材１６と一対のばね取付部材１７が取付けられる。前支持部材１６は、前フレーム１４の左右部から前方に延出し、かつ前フレーム１４と略並行に延出する。ばね取付部材１７は、前フレーム１４の中央近傍の左右部から後下方に延出する。   As shown in FIG. 1, a front support member 16 and a pair of spring attachment members 17 are attached to the front frame 14. The front support member 16 extends forward from the left and right portions of the front frame 14 and extends substantially parallel to the front frame 14. The spring mounting member 17 extends rearward and downward from the left and right portions near the center of the front frame 14.

フレーム１１ａには、図１，２に示すようにパッド１１ｂの裏面を支持するパッド支持装置１が取付けられる。パッド支持装置１は、ばね部材２とワイヤ３を有する。ばね部材２は、弾性材料、例えばばね鋼などのばね金属から形成される。ばね部材２は、棒部材であって、断面形状が円形である。ばね部材２には、強度を強くするために焼入れが施されることが好ましい。   As shown in FIGS. 1 and 2, a pad support device 1 that supports the back surface of the pad 11b is attached to the frame 11a. The pad support device 1 includes a spring member 2 and a wire 3. The spring member 2 is formed of an elastic material, for example, a spring metal such as spring steel. The spring member 2 is a rod member and has a circular cross-sectional shape. The spring member 2 is preferably subjected to quenching in order to increase the strength.

ばね部材２は、図１に示すようにシートクッション１１の前後方向に延出する第一部２ａと、シートクッション１１の幅方向に延出する第二部２ｂを交互に連続して複数有する。ばね部材２は、Ｓ字形状を連続して有するＳばねであって、幅方向に屈曲または湾曲しながら前後方向に延出する。第一部２ａと第二部２ｂは、パッド１１ｂの裏面に沿って設置され、パッド１１ｂの裏面を広い領域において裏側から支持する。   As shown in FIG. 1, the spring member 2 includes a plurality of first portions 2 a that extend in the front-rear direction of the seat cushion 11 and second portions 2 b that extend in the width direction of the seat cushion 11. The spring member 2 is an S spring continuously having an S shape, and extends in the front-rear direction while being bent or curved in the width direction. The first part 2a and the second part 2b are installed along the back surface of the pad 11b, and support the back surface of the pad 11b from the back side in a wide area.

ばね部材２は、図２に示すように前端部２ｃがばね取付部材１７の上面に取付けられ、後端部２ｄがスライド部材１８を介して後フレーム１５の上部に取付けられる。スライド部材１８は、樹脂製であって、断面円弧形状で、後フレーム１５の外周面にスライド可能に取付けられる。したがってばね部材２が上方から力を受けると、スライド部材１８がばね部材２とともに後フレーム１５に対して回転する。   As shown in FIG. 2, the front end 2 c of the spring member 2 is attached to the upper surface of the spring attachment member 17, and the rear end 2 d is attached to the upper portion of the rear frame 15 via the slide member 18. The slide member 18 is made of resin and has a circular arc shape in cross section, and is slidably attached to the outer peripheral surface of the rear frame 15. Therefore, when the spring member 2 receives a force from above, the slide member 18 rotates with respect to the rear frame 15 together with the spring member 2.

ばね部材２は、図２に示すように下側に凹んでおり、前傾斜部２ｅと後傾斜部２ｆを有する。前傾斜部２ｅは、前端部２ｃから下後方に延出し、最下部２ｇまで延出する。最下部２ｇは、シートクッション１１に着座する使用者の体重が最も集中しすい臀部（Ｈポイント）の下側に位置する。後傾斜部２ｆは、最下部２ｇから後フレーム１５の上面に向けて上後方に延出する。   As shown in FIG. 2, the spring member 2 is recessed downward, and has a front inclined portion 2e and a rear inclined portion 2f. The front inclined portion 2e extends downward and rearward from the front end portion 2c and extends to the lowermost portion 2g. The lowest part 2g is located below the heel part (H point) where the weight of the user sitting on the seat cushion 11 is most concentrated. The rear inclined portion 2 f extends upward and rearward from the lowermost portion 2 g toward the upper surface of the rear frame 15.

ばね部材２は、図１に示すようにシートクッション１１の幅中心に位置するワイヤ３の両側に設置される。ワイヤ３と各サイドフレーム１３の間には、それぞれ二本のばね部材２が設置される。二本のばね部材２は、左右対称の向きに配向される。複数のばね部材２は、シートクッション１１の幅方向に所定間隔で平行に設置される。   The spring member 2 is installed on both sides of the wire 3 positioned at the center of the width of the seat cushion 11 as shown in FIG. Two spring members 2 are installed between the wire 3 and each side frame 13. The two spring members 2 are oriented in symmetrical directions. The plurality of spring members 2 are installed in parallel in the width direction of the seat cushion 11 at a predetermined interval.

ワイヤ３は、ばね部材２よりも弾性変形し難い材料、例えば鋼などの金属材料から形成される。ワイヤ３は、棒部材であって、断面形状が円形である。ワイヤ３の直径は、ばね部材２よりも大きく、さらにばね部材２より弾性変形し難い構成になっている。   The wire 3 is made of a material that is less elastically deformed than the spring member 2, for example, a metal material such as steel. The wire 3 is a rod member and has a circular cross-sectional shape. The diameter of the wire 3 is larger than that of the spring member 2 and is more difficult to elastically deform than the spring member 2.

ワイヤ３は、図１，２に示すようにワイヤ本体部３ａとワイヤ前部３ｂを一体的に有する。ワイヤ本体部３ａは、前フレーム１４と後フレーム１５の間を前後方向に延出する。ワイヤ前部３ｂは、前フレーム１４と前支持部材１６の間を延出する。ワイヤ３は、シートクッション１１の幅中心において前後方向に延出する。   As shown in FIGS. 1 and 2, the wire 3 integrally includes a wire main body portion 3 a and a wire front portion 3 b. The wire main body 3 a extends between the front frame 14 and the rear frame 15 in the front-rear direction. The wire front portion 3 b extends between the front frame 14 and the front support member 16. The wire 3 extends in the front-rear direction at the center of the width of the seat cushion 11.

ワイヤ本体部３ａは、図２に示すように前端部３ｃが前フレーム１４の上部に取付けられ、後端部３ｄが後フレーム１５の上部に取付けられる。ワイヤ本体部３ａは、下側に凹んでおり、前傾斜部３ｅと後傾斜部３ｆを有する。前傾斜部３ｅは、前端部３ｃから下後方に延出し、最下部３ｇまで延出する。最下部３ｇは、シートクッション１１に着座する使用者の臀部（Ｈポイント）の下側に位置する。後傾斜部３ｆは、最下部３ｇから後フレーム１５の上面に向けて上後方に延出する。   As shown in FIG. 2, the wire body 3 a has a front end 3 c attached to the upper part of the front frame 14 and a rear end 3 d attached to the upper part of the rear frame 15. The wire main body 3a is recessed downward and has a front inclined portion 3e and a rear inclined portion 3f. The front inclined portion 3e extends downward and rearward from the front end portion 3c and extends to the lowermost portion 3g. The lowermost part 3g is located below the buttocks (H point) of the user who sits on the seat cushion 11. The rear inclined portion 3 f extends upward and rearward from the lowermost portion 3 g toward the upper surface of the rear frame 15.

図２に示すように前傾斜部３ｅは、前端部３ｃから延出する急傾斜部３ｅ１と、急傾斜部３ｅ１から延出する緩傾斜部３ｅ２を有する。急傾斜部３ｅ１と緩傾斜部３ｅ２は、いずれもばね部材２の前傾斜部２ｅよりも水平線に対して大きな角度を有する。急傾斜部３ｅ１は、緩傾斜部３ｅ２よりも水平線に対して大きな角度を有する。   As shown in FIG. 2, the front inclined part 3e has a steeply inclined part 3e1 extending from the front end part 3c and a gently inclined part 3e2 extending from the steeply inclined part 3e1. Both the steeply inclined portion 3e1 and the gently inclined portion 3e2 have a larger angle with respect to the horizontal line than the front inclined portion 2e of the spring member 2. The steeply inclined portion 3e1 has a larger angle with respect to the horizontal line than the gently inclined portion 3e2.

ワイヤ３の前端部３ｃと後端部３ｄは、図２に示すようにそれぞればね部材２の前端部２ｃと後端部２ｄと略同じ高さに位置する。ワイヤ３の前傾斜部３ｅと後傾斜部３ｆは、それぞればね部材２の前傾斜部２ｅと後傾斜部２ｆよりもパッド１１ｂの裏面よりも下側に位置する。ワイヤ３は、最下部３ｇにおいて最もばね部材２と上下方向に離れ、最下部２ｇ，３ｇ間は例えば２０±１０ｍｍに設定される。   The front end portion 3c and the rear end portion 3d of the wire 3 are positioned at substantially the same height as the front end portion 2c and the rear end portion 2d of the spring member 2, respectively, as shown in FIG. The front inclined portion 3e and the rear inclined portion 3f of the wire 3 are positioned below the back surface of the pad 11b with respect to the front inclined portion 2e and the rear inclined portion 2f of the spring member 2, respectively. The wire 3 is separated from the spring member 2 in the vertical direction at the lowermost part 3g, and the distance between the lowermost parts 2g and 3g is set to 20 ± 10 mm, for example.

パッド１１ｂは、弾性変形しやすい材料、例えばウレタンなどの発砲樹脂材料から形成される。パッド１１ｂは、図１，２に示すようにパッド支持装置１とフレーム１１ａの上に設置される。そのためパッド１１ｂの裏面は、通常、ばね部材２とワイヤ前部３ｂとフレーム１１ａの一部によって支持される。   The pad 11b is made of a material that is easily elastically deformed, for example, a foamed resin material such as urethane. The pad 11b is installed on the pad support device 1 and the frame 11a as shown in FIGS. Therefore, the back surface of the pad 11b is normally supported by a part of the spring member 2, the wire front portion 3b, and the frame 11a.

シートクッション１１に使用者が着座し、シートクッション１１に表面から裏側に向けて使用者の体重が加わると、パッド１１ｂとばね部材２が弾性変形する。使用者が通常の成人男性である場合、ばね部材２とワイヤ３が略同じ高さになる。それ以上の力がパッド１１ｂに加わると、パッド１１ｂの裏面がワイヤ３に当接する。これによりパッド１１ｂの裏方向へ変形がワイヤ３によって規制される。その結果、パッド１１ｂのみならず、ばね部材２の裏方向への変形もワイヤ３によって規制される。   When the user sits on the seat cushion 11 and the weight of the user is applied to the seat cushion 11 from the front side to the back side, the pad 11b and the spring member 2 are elastically deformed. When the user is a normal adult male, the spring member 2 and the wire 3 have substantially the same height. When more force is applied to the pad 11b, the back surface of the pad 11b comes into contact with the wire 3. Thereby, the deformation in the back direction of the pad 11 b is restricted by the wire 3. As a result, not only the pad 11 b but also the deformation of the spring member 2 in the reverse direction is restricted by the wire 3.

以上のようにパッド支持装置１は、図２に示すようにパッド１１ｂの裏面を弾性的に支持しかつ両端部がフレーム１１ａに取付けられるばね部材２と、ばね部材２よりも弾性変形し難い材料から形成されかつ両端部がフレーム１１ａに取付けられるワイヤ３を有する。ワイヤ３は、ばね部材２よりもパッド１１ｂの裏面から離れた位置で、かつパッド１１ｂまたはばね部材２の裏方向への弾性変形量を規制し得る位置に設置される。   As described above, the pad support device 1 includes the spring member 2 that elastically supports the back surface of the pad 11b and is attached to the frame 11a as shown in FIG. 2, and a material that is less elastically deformed than the spring member 2. And both ends of the wire 3 are attached to the frame 11a. The wire 3 is installed at a position farther from the back surface of the pad 11b than the spring member 2 and at a position where the elastic deformation amount in the back direction of the pad 11b or the spring member 2 can be regulated.

したがってシート１０に着座した使用者の重みがパッド１１ｂの表側に加わると、パッド１１ｂとばね部材２が弾性変形する。そのためパッドのみが弾性変形するシート等に比べて、シート１０の弾性変形量がばね部材２の弾性変形によって多くなり、シート１０の座り心地が向上する。またパッド支持装置１は、ばね部材２よりも弾性変形し難いワイヤ３を有し、かつワイヤ３がばね部材２よりもパッド１１ｂの裏面から離れた位置に設置される。したがってパッド１１ｂの表側から裏側に大きな力が加わると、パッド１１ｂがワイヤ３に当たる。これによりパッド１１ｂまたはばね部材２の裏側への弾性変形がワイヤ３によって規制され得る。かくしてシート１０が大きく変形し過ぎることで、使用者の姿勢が崩れることがワイヤ３によって抑制され得る。その結果、シート１０の座り心地が向上する。   Therefore, when the weight of the user seated on the seat 10 is applied to the front side of the pad 11b, the pad 11b and the spring member 2 are elastically deformed. Therefore, the amount of elastic deformation of the seat 10 is increased by the elastic deformation of the spring member 2 as compared with a seat or the like in which only the pad is elastically deformed, and the seating comfort of the seat 10 is improved. The pad support device 1 has a wire 3 that is less likely to be elastically deformed than the spring member 2, and the wire 3 is installed at a position farther from the back surface of the pad 11 b than the spring member 2. Therefore, when a large force is applied from the front side to the back side of the pad 11 b, the pad 11 b hits the wire 3. Thereby, the elastic deformation to the back side of the pad 11b or the spring member 2 can be regulated by the wire 3. Thus, when the sheet 10 is deformed excessively, the user 3 can be prevented from collapsing the posture of the user. As a result, the seating comfort of the seat 10 is improved.

またパッド１１ｂまたはばね部材２の裏側への弾性変形が規制されることで、パッド１１ｂの裏側に位置する周辺部材に力が加わることがワイヤ３によって規制され得る。かくして力を受けて周辺部材が破損することがワイヤ３によって抑制され得る。あるいはパッド１１ｂまたはばね部材２が予想以上に変形することがワイヤ３によって規制され得る。そのため予想以上に変形することでパッド１１ｂとばね部材２が破損することがワイヤ３によって抑制され得る。   Moreover, the elastic deformation to the back side of the pad 11b or the spring member 2 is controlled, so that the force applied to the peripheral member located on the back side of the pad 11b can be controlled by the wire 3. Thus, the wire 3 can suppress the peripheral member from being damaged by receiving the force. Alternatively, the wire 3 can restrict the pad 11b or the spring member 2 from being deformed more than expected. Therefore, the wire 3 can suppress the pad 11b and the spring member 2 from being damaged by being deformed more than expected.

またばね部材２とワイヤ３は、図１に示すようにパッド１１ｂの厚み方向に対して相互に重ならない位置に配されている。したがってばね部材２は、ワイヤ３に邪魔されることなく、ワイヤ３の位置まで弾性変形し得る。そのためばね部材とワイヤが相互に重なる構造に比べ、パッド支持装置１の厚みを厚くすることなく、ばね部材２の弾性変形量を大きくすることができる。   Further, as shown in FIG. 1, the spring member 2 and the wire 3 are arranged at positions that do not overlap each other in the thickness direction of the pad 11b. Therefore, the spring member 2 can be elastically deformed to the position of the wire 3 without being obstructed by the wire 3. Therefore, the elastic deformation amount of the spring member 2 can be increased without increasing the thickness of the pad support device 1 as compared with the structure in which the spring member and the wire overlap each other.

またワイヤ３は、図１に示すようにシート１０の幅中心に位置する。したがってシート１０が使用者から力を受けると、シート１０は、通常、幅中心近傍を中心に弾性変形する。これに対してワイヤ３は、シート１０の幅中心に位置しているため、シート１０およびパッド１１ｂの弾性変形を確実かつ効果的に規制することができる。   The wire 3 is positioned at the center of the width of the sheet 10 as shown in FIG. Therefore, when the sheet 10 receives a force from the user, the sheet 10 usually elastically deforms around the width center. On the other hand, since the wire 3 is located at the center of the width of the sheet 10, the elastic deformation of the sheet 10 and the pad 11b can be reliably and effectively restricted.

（他の実施の形態）
本発明は、上記実施の形態に限定されず、以下の形態等であっても良い。例えば、図１，２に示すパッド支持装置１は、シートクッション１１に設けられている。しかしパッド支持装置がシートバックに設けられても良い。この場合、ばね部材とワイヤは、上下方向に延出し、上下端部がフレームに取付けられることが好ましい。 (Other embodiments)
The present invention is not limited to the above-described embodiment, and may be the following form. For example, the pad support device 1 shown in FIGS. 1 and 2 is provided on the seat cushion 11. However, a pad support device may be provided on the seat back. In this case, it is preferable that the spring member and the wire extend in the vertical direction, and the upper and lower ends are attached to the frame.

図１に示すばね部材２は、シートクッション１１の幅方向に対して屈曲または湾曲しながら前後方向に延出する。しかしばね部材が幅方向に屈曲または湾曲せず、前後方向に延出しても良い。図２に示すワイヤ３は、両端部を除く略全体がばね部材２よりもパッド１１ｂの裏面から離れている。しかしワイヤが両端部を含む全部分においてばね部材よりもパッドの裏面から離れていても良い。あるいはワイヤが中央部分においてばね部材よりもパッドの裏面から離れていても良い。   The spring member 2 shown in FIG. 1 extends in the front-rear direction while being bent or curved with respect to the width direction of the seat cushion 11. However, the spring member may extend in the front-rear direction without being bent or curved in the width direction. The wire 3 shown in FIG. 2 is separated from the back surface of the pad 11b more than the spring member 2 except for both ends. However, the wire may be further away from the back surface of the pad than the spring member in all parts including both ends. Alternatively, the wire may be further away from the back surface of the pad than the spring member at the central portion.

図１に示すばね部材２とワイヤ３は、パッド１１ｂの厚み方向に対して相互に重ならない位置に配されている。しかしばね部材とワイヤがパッドの厚み方向に対して一部重なるように配され、パッドとばね部材が大きく変形した際にばね部材がワイヤに当たっても良い。図１に示すシート１０は、一人用シートであるが、複数人用シートであっても良い。乗物は、自動車、バスなどの車両でも良いが、船舶や航空機などであっても良い。   The spring member 2 and the wire 3 shown in FIG. 1 are arranged at positions that do not overlap each other in the thickness direction of the pad 11b. However, the spring member and the wire may be arranged so as to partially overlap in the thickness direction of the pad, and the spring member may hit the wire when the pad and the spring member are greatly deformed. The sheet 10 shown in FIG. 1 is a single-person sheet, but may be a multiple-person sheet. The vehicle may be a vehicle such as an automobile or a bus, but may be a ship or an aircraft.
