Description

本発明は車両用シートパッドに係り、特に、軽量化しうる車両用シートパッドに関する。   The present invention relates to a vehicle seat pad, and more particularly to a vehicle seat pad that can be reduced in weight.

車両用シートパッド（以下、単にシートパッドということがある。）は、一般に軟質ポリウレタンフォーム又は半硬質ポリウレタンフォーム等の発泡体で構成されている。   A vehicle seat pad (hereinafter sometimes simply referred to as a seat pad) is generally composed of a foamed material such as a flexible polyurethane foam or a semi-rigid polyurethane foam.

特開平１１−３４７１０号公報には、シートパッドの底面から上方に向って凹陥する凹部が設けられると共に、該凹部にスラブが挿入されており、該スラブの上面部分にセンサが設置された着座センサ付き座席が記載されている。このスラブはシートパッドと同一のウレタンフォーム等よりなる（同号公報第００１１段落）。   Japanese Patent Application Laid-Open No. 11-34710 discloses a seating sensor in which a recess that is recessed upward from the bottom surface of a seat pad is provided, a slab is inserted into the recess, and a sensor is installed on the upper surface of the slab. With seats listed. This slab is made of the same urethane foam as the seat pad (paragraph 0011 of the same publication).

同号公報には、シートパッドを軽量化しようという技術的目的はない。   The publication does not have the technical purpose of reducing the weight of the seat pad.

なお、シートパッドを軽量化するために、シートパッドの底面から上方に向って凹陥する凹部を設け、この凹部を空洞のままとする（即ち、所謂「肉盗みする」）ことが考えられるが、このようにすると、シートパッドの底面付近の剛性が低くなり、シートパッドに座ったときに底付き感が感取され易くなる。   In order to reduce the weight of the seat pad, it is conceivable to provide a concave portion that is recessed upward from the bottom surface of the seat pad and leave the concave portion hollow (that is, so-called “stealing meat”). If it does in this way, the rigidity of the bottom face vicinity of a seat pad will become low, and it will become easy to sense a feeling of bottom when sitting on a seat pad.

また、シートパッドを軽量化するために、シートパッドの座面に溝を設けることも考えられるが、このようにすると、シートパッドに座ったときに凹凸異物感が感取されるようになる。
特開平１１−３４７１０号公報 Further, in order to reduce the weight of the seat pad, it is conceivable to provide a groove on the seating surface of the seat pad. However, in this way, when the user sits on the seat pad, the sensation of uneven foreign matter is sensed.
JP 11-34710 A

本発明は、座り心地、乗り心地に優れた、軽量化可能な車両用シートパッドを提供することを目的とする。   An object of the present invention is to provide a vehicle seat pad that is excellent in sitting comfort and riding comfort and can be reduced in weight.

本発明（請求項１）の車両用シートパッドは、外部に連通した空孔が内部に延設されていることを特徴とするものである。   The vehicle seat pad of the present invention (Claim 1) is characterized in that a hole communicating with the outside is extended inside.

請求項２の車両用シートパッドは、請求項１において、該空孔の孔径は１〜５０ｍｍであることを特徴とするものである。   A vehicle seat pad according to a second aspect of the present invention is the vehicle seat pad according to the first aspect, wherein the hole diameter is 1 to 50 mm.

請求項３の車両用シートパッドは、請求項１又は２において、該空孔の体積は車両用シートパッドの体積の１〜１０％であることを特徴とするものである。   A vehicle seat pad according to a third aspect is characterized in that, in the first or second aspect, the volume of the holes is 1 to 10% of the volume of the vehicle seat pad.

請求項４の車両用シートパッドは、請求項１ないし３のいずれか１項において、該空孔の端部が車両用シートパッドの座面に臨んでいることを特徴とするものである。   According to a fourth aspect of the present invention, there is provided the vehicle seat pad according to any one of the first to third aspects, wherein an end of the air hole faces a seating surface of the vehicle seat pad.

請求項５の車両用シートパッドは、請求項４において、該空孔の端部が車両用シートパッドの座面の複数箇所に臨んでいることを特徴とするものである。   According to a fifth aspect of the present invention, the vehicle seat pad according to the fourth aspect is characterized in that the end of the hole faces a plurality of locations on the seating surface of the vehicle seat pad.

請求項６の車両用シートパッドは、請求項５において、該空孔の端部が車両用シートパッドの座面に臨んでいることを特徴とするものである。   According to a sixth aspect of the present invention, the vehicle seat pad according to the fifth aspect is characterized in that an end of the air hole faces a seating surface of the vehicle seat pad.

本発明の車両用シートパッドは、空孔を有しているので、その分だけ軽量化することができる。本発明では、この空孔がシートパッド内部に設けられているので、座ったときの異物感が無く、また底面付近の剛性低下が防止されるところから底付き感も防止ないし抑制される。この空孔が外部に連通しているので、車両用シートパッドのクッション性も良好である。   Since the vehicle seat pad of the present invention has holes, the weight can be reduced accordingly. In the present invention, since the holes are provided in the seat pad, there is no sense of foreign matter when sitting, and a feeling of bottoming is also prevented or suppressed since a reduction in rigidity near the bottom surface is prevented. Since this hole communicates with the outside, the cushioning property of the vehicle seat pad is also good.

この空孔の孔径を１〜５０ｍｍとすることにより、上記の底付き感を確実に防止することができる。空孔の体積を１〜１０％とすることにより、底付き感をより確実に防止することができる。   By setting the hole diameter to 1 to 50 mm, the above-mentioned feeling of bottom can be surely prevented. By setting the volume of the pores to 1 to 10%, it is possible to more reliably prevent the feeling of bottoming.

空孔の端部がシートパッドの座面に臨んでいる場合には、底面から座面へ空気が流出するという長所がある。この場合、この空孔の端部が座面の複数箇所に臨んでいると、シートパッドに座ったときに空孔が乗員によって蓋をされた状態とならず、空孔から空気が外部に確実に流出するようになる。   When the edge of the hole faces the seat surface of the seat pad, there is an advantage that air flows out from the bottom surface to the seat surface. In this case, if the end of the hole faces a plurality of locations on the seating surface, the hole is not covered by the occupant when sitting on the seat pad, and air is reliably released from the hole to the outside. Will be leaked.

空孔に端部がシートパッドの底面に臨んでいる場合には、底面より空気を送り込むことができるという長所がある。   When the end portion of the hole faces the bottom surface of the seat pad, there is an advantage that air can be fed from the bottom surface.

空孔を、車両用シートパッドの左右幅方向の中央を前後方向に延在した前後方向部と、該前後方向部に連なり、該車両用シートパッドの左右幅方向に延在した横方向部とを有する構成とした場合には、シートパッドのクッション特性が広い範囲にわたって均等化されるようになる。   A front-rear direction part extending in the front-rear direction at the center in the left-right width direction of the vehicle seat pad; and a lateral part extending in the left-right width direction of the vehicle seat pad; In the case of the configuration having the above, the cushion characteristics of the seat pad are equalized over a wide range.

以下に図面を参照して本発明の車両用シートパッドの実施の形態を説明する。   Embodiments of a vehicle seat pad according to the present invention will be described below with reference to the drawings.

第１図は本発明の車両用シートパッドの実施の形態を示す斜視図であり、第２図は第１図のII−II線に沿う断面図である。   FIG. 1 is a perspective view showing an embodiment of a vehicle seat pad according to the present invention, and FIG. 2 is a sectional view taken along line II-II in FIG.

この車両用シートパッド１は、尻下部２、腿下部３及びサイド部４を有する。   The vehicle seat pad 1 includes a bottom part 2, a thigh part 3, and a side part 4.

このシートパッドは、ポリウレタンフォームよりなる。クッション性を重視する車両用シートパッド、或いはシートパッドの上にカバー材として厚さ５ｍｍ以上のソフトウレタンやそれに類するものが用いられている場合は、シートパッドの構成材料としては、コア密度２５〜７０ｋｇ／ｍ３、２５％硬度１５〜２５ｋｇｆ／φ２００のポリウレタンフォームが望ましい。 This seat pad is made of polyurethane foam. In the case where a soft urethane having a thickness of 5 mm or more or a similar material is used as a cover material on a vehicle seat pad that emphasizes cushioning properties or a seat pad, the core density is 25 to 25. A polyurethane foam having 70 kg / m 3 and 25% hardness of 15 to 25 kgf / φ200 is desirable.

一方、表面にソフト感が望まれるシートパッドあるいは初期の着座フィーリングを良くすることを目指すシートパッドの場合、シートパッドの構成材料としては、コア密度３０〜７０ｋｇ／ｍ３、２５％硬度８〜２０ｋｇｆ／φ２００のポリウレタンフォームが望ましい。 On the other hand, in the case of a seat pad for which a soft feeling is desired on the surface or a seat pad aiming to improve the initial seating feeling, the constituent material of the seat pad is a core density of 30 to 70 kg / m 3 , 25% hardness of 8 to 8 A polyurethane foam of 20 kgf / φ200 is desirable.

このシートパッド１内には、外部に連通した空孔５が延設されている。この実施の形態では、空孔５は、シートパッド１の左右幅方向の中央部を前後方向に延在した前後方向部５ａと、該前後方向部５ａの前端から上方に立ち上がる起立部５ｂと、前後方向部５ａの後端から下方に立ち下がる立下部５ｃとを有した略クランク形側面視形状のものである。起立部５ｂの上端はシートパッド１の座面に臨んでおり、立下部５ｃの下端はシートパッド１の底面に臨んでいる。   In this seat pad 1, a hole 5 communicating with the outside is extended. In this embodiment, the hole 5 includes a front-rear direction portion 5a extending in the front-rear direction at the center in the left-right width direction of the seat pad 1, and a standing portion 5b rising upward from the front end of the front-rear direction portion 5a, It is of a substantially crank-shaped side view shape having a lower end portion 5c that falls downward from the rear end of the front-rear direction portion 5a. The upper end of the standing portion 5 b faces the seat surface of the seat pad 1, and the lower end of the standing portion 5 c faces the bottom surface of the seat pad 1.

この実施の形態では、空孔５は１本だけ設けられているが、これと平行に２本以上設けてもよく、さらに他の部位に空孔を設けてもよく、他の方向に延在する空孔を設けてもよい。   In this embodiment, only one hole 5 is provided, but two or more holes may be provided in parallel therewith, and holes may be provided in other parts, extending in other directions. You may provide the hole to do.

このように空孔５を設けた車両用シートパッド１は、空孔５を設けた分だけ軽量である。また、この空孔５は、端部の開放部を除いてシートパッド１の内部に設けられているので、座ったときに座面から受ける感触が良好であると共に、シートパッド１の底面付近の剛性が高く、底付き感もない。   Thus, the vehicle seat pad 1 provided with the holes 5 is lighter by the amount provided with the holes 5. Further, since the holes 5 are provided inside the seat pad 1 except for the open portions at the ends, the feeling received from the seat surface when sitting is good and the vicinity of the bottom surface of the seat pad 1 is also provided. High rigidity and no bottoming.

第３図は別の実施の形態に係る車両用シートパッド１Ａの斜視図、第４図はその空孔の構成を示す斜視図である。   FIG. 3 is a perspective view of a vehicle seat pad 1A according to another embodiment, and FIG. 4 is a perspective view showing the structure of the air holes.

この実施の形態では、空孔６は、シートパッド１Ａの尻下部の左右幅方向中央付近を前後方向に延在する前後方向部６ａと、該前後方向部６ａの前端から若干右斜め前方及び左斜め前方に分岐して延在する２条の前後方向部６ｂとを有する。   In this embodiment, the hole 6 includes a front-rear direction portion 6a extending in the front-rear direction near the center in the left-right width direction of the bottom portion of the seat pad 1A, and a slightly diagonally forward and left-hand side from the front end of the front-rear direction portion 6a. It has two front and rear direction parts 6b which branch and extend diagonally forward.

また、この空孔６は、各前後方向部６ｂの前端からシートパッド１の側方に向って延在する横方向部６ｃと、各前後方向部６ｂの長手方向の途中からシートパッド１の側方に向って延在する横方向部６ｄと、前後方向部６ａの長手方向の途中からシートパッド１の側方に向って延在する横方向部６ｅとを有する。   Further, the air holes 6 include a lateral portion 6c extending from the front end of each front-rear direction portion 6b toward the side of the seat pad 1, and a side of the seat pad 1 from the middle in the longitudinal direction of each front-rear direction portion 6b. A lateral portion 6d extending toward the side, and a lateral portion 6e extending toward the side of the seat pad 1 from the middle in the longitudinal direction of the front-rear direction portion 6a.

空孔６は、各横方向部６ｃ，６ｄの先端と途中からそれぞれ上方に延在する起立部６ｆ，６ｇを有すると共に、各横方向部６ｅの先端から上方に延在する起立部６ｈを有する。これらの起立部６ｆ，６ｇ，６ｈの上端はシートパッド１の座面に臨んでいる。   The air hole 6 has upright portions 6f and 6g extending upward from the front ends of the lateral direction portions 6c and 6d, respectively, and has upright portions 6h extending upward from the front ends of the horizontal direction portions 6e. . The upper ends of the upright portions 6f, 6g, and 6h face the seat surface of the seat pad 1.

空孔６は、さらに、前後方向部６ａの前端付近から下方に延在する立下部６ｉを有する。この立下部６ｉの下端はシートパッド１の底面に臨んでいる。   The air hole 6 further has a standing portion 6i extending downward from the vicinity of the front end of the front-rear direction portion 6a. The lower end of the standing part 6 i faces the bottom surface of the seat pad 1.

この車両用シートパッド１Ａの空孔以外の構成は前記車両用シートパッド１と同一であり、同一符号は同一部分を示している。   The configuration of the vehicle seat pad 1A other than the holes is the same as that of the vehicle seat pad 1, and the same reference numerals indicate the same parts.

この車両用シートパッド１Ａも、座ったときに座面から受ける感触が良好であると共に、底付き感もない。特に、この実施の形態にあっては、空孔が座面の下方の広い領域にわたって設けられており、尻下部から腿下部にかけての広い範囲にわたってシートパッドのクッション特性が略均一なものとなる。   The vehicle seat pad 1A also has a good feel from the seat surface when sitting, and does not have a feeling of bottoming. In particular, in this embodiment, the holes are provided over a wide area below the seating surface, and the cushion characteristics of the seat pad are substantially uniform over a wide range from the bottom of the buttocks to the bottom of the thigh.

なお、これらの車両用シートパッド１，１Ａにおいては、前後方向部５ａ，６ａ，６ｂは、シートパッドの座面よりも１０ｍｍ以上、特に２０ｍｍ以上深い位置に設けられていることが好ましく、且つシートパッドの底面よりも１０ｍｍ以上特に２０ｍｍ以上上方に設けられていることが好ましい。   In these vehicle seat pads 1 and 1A, the front-rear direction portions 5a, 6a, and 6b are preferably provided at a position that is 10 mm or more, particularly 20 mm or more deeper than the seat surface of the seat pad. It is preferable to be provided 10 mm or more, particularly 20 mm or more above the bottom surface of the pad.

なお、空孔５，６の孔径（直径）は１〜５０ｍｍ特に１０〜２０ｍｍ程度が好ましい。空孔の体積はシートパッドの体積の１〜１０％特に１．５〜４％程度が好適である。   The hole diameter (diameter) of the holes 5 and 6 is preferably about 1 to 50 mm, particularly about 10 to 20 mm. The volume of the pores is preferably about 1 to 10%, particularly about 1.5 to 4% of the volume of the seat pad.

シートパッドに空孔を形成する方法の一例について第５，６図を参照して説明する。   An example of a method for forming holes in the seat pad will be described with reference to FIGS.

このシートパッドは、金型内にウレタン原液を供給して発泡成形することにより形成されるが、第５図の方法では、金型内に崩解性の中子（この実施の形態は砂を成形してなる中子）７を配置しておく。ウレタンの発泡後に成形体を金型から脱型し、次いで中子７を例えばほじくり出す如くして除去することにより、空孔５が形成される。空孔６も同様にして形成することができる。崩解性の中子を用いる代りに、硬質ウレタンフォームや、ポリプロピン等の合成樹脂あるいはゴム製の中子を用い、成形体を脱型した後、成形体から中子を引き出すことにより空孔を形成してもよい。   This seat pad is formed by supplying a urethane stock solution into a mold and foam-molding. However, in the method of FIG. 5, a disintegrating core (in this embodiment, sand is used) in the mold. A molded core 7 is placed in advance. The voids 5 are formed by removing the molded body from the mold after foaming of urethane, and then removing the core 7 by, for example, removing the core 7. The holes 6 can be formed in the same manner. Instead of using a disintegrating core, a rigid urethane foam, a synthetic resin such as polypropine or a rubber core is used, and after removing the molded body, the holes are drawn out by pulling the core out of the molded body. It may be formed.

第６図の方法では、金型７に両端部が蓋状部８ａ，８ｂによって閉鎖された閉チューブ状であり、且つ空孔５と同一の略クランク形側面視形状の閉チューブ状中子８を配置しておく。第６図（ａ）の如く成形体を金型から脱型した後、中子８の両端の蓋状部８ａ，８ｂを切除する。チューブ状中子８はそのまま成形体内に残置させる。この中子８内が空孔５となる。この中子８の材質としては軟質なポリプロピレン、シリコン樹脂等の合成樹脂やゴムが好適である。この方法によれば、シートパッド１Ａの空孔６のように複雑な形状の空孔を容易に形成することができる。   In the method shown in FIG. 6, a closed tube-shaped core 8 having a closed tube shape in which both ends are closed by lid-shaped portions 8 a and 8 b and a substantially crank-shaped side view shape identical to the hole 5 is used. Is placed. After the molded body is removed from the mold as shown in FIG. 6 (a), the lid portions 8a and 8b at both ends of the core 8 are cut off. The tubular core 8 is left as it is in the molded body. The inside of the core 8 becomes a hole 5. As the material of the core 8, a synthetic resin such as soft polypropylene or silicon resin, or rubber is preferable. According to this method, it is possible to easily form a complicatedly shaped hole such as the hole 6 of the seat pad 1A.

実施例１
シートパッド本体にＪＩＳ Ｋ ６４０１に規定する硬さが２４５Ｎのウレタンフォームを用い、第３，４図に示す車両用シートパッド１を製造し、その尻下部における座圧分布を測定した。孔６の径は１５ｍｍ、前後方向部６ａ，６ｂの合計の長さは２６０ｍｍ、前後方向部６ａ，６ｂの座面からの平均深さは４０ｍｍとした。その結果を第７図に示す。 Example 1
The vehicle seat pad 1 shown in FIGS. 3 and 4 was manufactured using urethane foam having a hardness of 245N as defined in JIS K 6401 for the seat pad body, and the seat pressure distribution at the bottom of the buttocks was measured. The diameter of the hole 6 was 15 mm, the total length of the front and rear direction parts 6a and 6b was 260 mm, and the average depth from the seating surface of the front and rear direction parts 6a and 6b was 40 mm. The result is shown in FIG.

比較例１
孔５の代りに座面に深さ２５ｍｍ、幅１５ｍｍであり、第７図の比較例１中に破線で示すパターンの溝を形成した他は実施例１と同一のシートパッドを製造し、その座圧分布を測定した。その結果を第７図に示す。 Comparative Example 1
A seat pad identical to that of Example 1 was manufactured, except that the seat surface had a depth of 25 mm and a width of 15 mm instead of the hole 5 and a groove having a pattern indicated by a broken line was formed in Comparative Example 1 in FIG. The sitting pressure distribution was measured. The result is shown in FIG.

第７図では、色の濃い部分ほど座圧が高い。第７図では図の下縁側が腿下であり、図の上縁側が尻下である。第７図より、本発明のシートパッドによると座圧分布が均等化されることが分る。   In FIG. 7, the deeper the color, the higher the sitting pressure. In FIG. 7, the lower edge side of the figure is the thigh, and the upper edge side of the figure is the buttocks. FIG. 7 shows that the seat pressure distribution is equalized according to the seat pad of the present invention.
