本発明は、自動車などの車両の座席クッション材として用いられるシートパッドに関する。   The present invention relates to a seat pad used as a seat cushion material of a vehicle such as an automobile.

従来、例えば、エアバッグ装置を具備する助手席のシートには、エアバッグの誤動作防止等の目的で、乗員の着座を検知するシート状の着座センサが内蔵されている。また、自動車シートには、冬期等の低温時に着座面を加熱して乗員の快適性を高めるためにシート状のヒータを内蔵する場合もある。   2. Description of the Related Art Conventionally, for example, a passenger seat that includes an airbag device incorporates a seat-like seating sensor that detects the seating of an occupant for the purpose of preventing malfunction of the airbag. In addition, a seat-like heater may be incorporated in an automobile seat in order to heat the seating surface at a low temperature such as in winter to enhance passenger comfort.

このような着座センサやヒータなどの機能シートを自動車シートに配設する際に、シートパッドの上面と表皮との間に介在させると、着座時に機能シートによる異物感を感じてしまう。そのため、異物感を解消するべく、機能シートをシートパッド内部に配設するための構造が種々提案されている。   When a functional sheet such as a seating sensor or a heater is disposed on an automobile seat, if the seat is interposed between the upper surface of the seat pad and the skin, a foreign object sensation due to the functional sheet will be felt when seated. For this reason, various structures for disposing the functional sheet inside the seat pad have been proposed in order to eliminate the foreign object feeling.

例えば、特開平１１−３４７１０号公報には、軟質なパッド本体の底面から上方に向かって穴を設け、この穴に軟質体である小パッドを挿入するとともに、該小パッドの上面と穴の天井面との間に着座センサを設置し、しかも、上記穴の下端を狭くすることで、小パッドを穴内に保持させる技術が開示されている。   For example, in Japanese Patent Laid-Open No. 11-34710, a hole is provided upward from the bottom surface of a soft pad body, a small pad that is a soft body is inserted into the hole, and the top surface of the small pad and the ceiling of the hole A technique for holding a small pad in a hole by disposing a seating sensor between the surface and narrowing the lower end of the hole is disclosed.

また、特開２０００−１８９２８２号公報には、パッド本体における着座面下方に格納空間部を設け、この格納空間部内に、上面にセンサ又はヒータを有する発泡体製のブロック体である小パッドを格納する技術が開示されている。
特開平１１−３４７１０号公報 特開２０００−１８９２８２号公報 Japanese Patent Laid-Open No. 2000-189282 discloses a storage space provided below a seating surface of a pad body, and a small pad, which is a foam block having a sensor or a heater on the upper surface, is stored in the storage space. Techniques to do this are disclosed.

図１は、実施形態に係るシートパッド１０の分解斜視図であり、図２（ａ）は同シートパッド１０の前後方向での縦断面図、（ｂ）はその分解図、図３は同シートパッドの左右方向での縦断面図、図４は同シートパッドの底面図である。   1 is an exploded perspective view of a seat pad 10 according to the embodiment, FIG. 2A is a longitudinal sectional view of the seat pad 10 in the front-rear direction, FIG. 1B is an exploded view thereof, and FIG. The longitudinal cross-sectional view in the left-right direction of a pad and FIG. 4 are bottom views of the seat pad.

このシートパッド１０は、自動車のシート座面部に用いられるクッションパッドであり、着座した人体を検知するための着座センサ１２を内部に配設してなる着座センサ付きのシートパッドである。シートパッド１０は、パッド本体１４と、その内部に上記着座センサ１２を配設するためにパッド本体１４とは別に成形された小パッド１６とを備えてなる。   The seat pad 10 is a cushion pad used for a seat surface portion of an automobile, and is a seat pad with a seating sensor in which a seating sensor 12 for detecting a seated human body is disposed. The seat pad 10 includes a pad main body 14 and a small pad 16 formed separately from the pad main body 14 in order to dispose the seating sensor 12 therein.

パッド本体１４は、金型内部にポリウレタンフォーム原料を注入して成型された軟質ポリウレタンフォームからなる発泡成形体であり、その底面には凹状の収容空間１８が形成されている。収容空間１８は、パッド本体１４における幅方向中央部の着座部２０であって、その前後方向中央部から後側の尻下部２２の下方に設けられており、パッド本体１４の底面から上方に向かって凹設されている。また、収容空間１８は、前後及び左右の側壁２４，２６，２８，３０で区画されてなる水平断面略矩形状をなしており、前後の側壁２４，２６は下方ほど幅広となるように傾斜し、左右の側壁２８，３０は天井面３２に対して略垂直に立設されており、これにより小パッド１６の挿入しやすさを確保している。   The pad main body 14 is a foamed molded body made of a flexible polyurethane foam molded by injecting a polyurethane foam raw material into a mold, and a concave accommodation space 18 is formed on the bottom surface thereof. The accommodation space 18 is a seating portion 20 at the center in the width direction of the pad main body 14, and is provided below the rear bottom portion 22 from the center in the front-rear direction, and upward from the bottom surface of the pad main body 14. Are recessed. The storage space 18 has a substantially rectangular horizontal section defined by front and rear and left and right side walls 24, 26, 28, and 30. The front and rear side walls 24 and 26 are inclined so as to become wider toward the bottom. The left and right side walls 28, 30 are erected substantially perpendicular to the ceiling surface 32, thereby ensuring ease of insertion of the small pad 16.

小パッド１６は、パッド本体１４と同様の軟質ポリウレタンフォームの発泡成形体からなり、上記収容空間１８内に隙間なくかつ着脱自在に装着されるものである。小パッド１６を形成するポリウレタンフォームは、パッド本体１４を形成するポリウレタンフォームと同じ配合でもよく、硬さ、密度などを変えた異なる配合とすることもできる。なお、小パッド１６としては、このような軟質フォームの発泡成形体には限られず、チップウレタンなどの各種軟質材を使用することができる。   The small pad 16 is made of a foamed flexible polyurethane foam similar to the pad main body 14 and is detachably mounted in the housing space 18 without a gap. The polyurethane foam that forms the small pad 16 may have the same composition as the polyurethane foam that forms the pad main body 14, or may have a different composition with different hardness, density, and the like. The small pad 16 is not limited to such a foamed molded body of flexible foam, and various soft materials such as chip urethane can be used.

小パッド１６の上面３４には、シートパッド１０上に着座した人体を検知するための感圧式のシート状着座センサ１２が接着固定されている。そして、このように着座センサ１２を備える小パッド１６を上記収容空間１８に装着することにより、着座センサ１２は、小パッド１６の上面３４と収容空間１８の天井面３２との間に挟まれた状態に設置されるようになっている。着座センサ１２への配線３６は、小パッド１６の上面に沿って収容空間１８の後壁２６から後方に引き出されており、その先端に端子３８を備える。なお、着座センサ１２は、小パッド１６の上面３４に予め接着しておく場合に限られず、収容空間１８の天井面３２に予め接着しておいてもよい。   A pressure-sensitive seat-like seating sensor 12 for detecting a human body seated on the seat pad 10 is bonded and fixed to the upper surface 34 of the small pad 16. The seat pad 12 is sandwiched between the upper surface 34 of the small pad 16 and the ceiling surface 32 of the housing space 18 by mounting the small pad 16 including the seating sensor 12 in the housing space 18 as described above. It is designed to be installed in the state. The wiring 36 to the seating sensor 12 is drawn rearward from the rear wall 26 of the accommodation space 18 along the upper surface of the small pad 16, and includes a terminal 38 at the tip thereof. The seating sensor 12 is not limited to the case where the seating sensor 12 is bonded in advance to the upper surface 34 of the small pad 16, and may be bonded in advance to the ceiling surface 32 of the accommodation space 18.

パッド本体１２の収容空間１８における相対する左右の側壁２８，３０には、内向きに突出する凸条５０がそれぞれ２本ずつ設けられており、該凸条５０は収容空間１８の下端開口側から上方の天井面３２まで延びて形成されている。２本の凸条５０，５０は、左右の側壁２８，３０の間で相対向するように前後方向での位置が同じ位置に配されている。また、収容空間１８の前側の側壁２４にも、同様の凸条５０が２本設けられているが、この実施形態では後側の側壁２６にはかかる凸条は設けられていない。   The left and right side walls 28, 30 in the storage space 18 of the pad main body 12 are provided with two ridges 50 protruding inward, respectively, and the ridges 50 are formed from the lower end opening side of the storage space 18. It is formed to extend to the upper ceiling surface 32. The two ridges 50, 50 are arranged at the same position in the front-rear direction so as to face each other between the left and right side walls 28, 30. In addition, although two similar ridges 50 are provided on the front side wall 24 of the accommodation space 18, no ridges are provided on the rear side wall 26 in this embodiment.

一方、小パッド１６には、上記凸条５０と嵌合するように、前側の側面４０及び左右の側面４２，４４に、その上下方向の全体にわたって延びる凹溝５２が、それぞれ２本ずつ設けられている。   On the other hand, in the small pad 16, two concave grooves 52 extending in the entire vertical direction are provided on the front side surface 40 and the left and right side surfaces 42 and 44, respectively, so as to be fitted to the ridges 50. ing.

このように収容空間１８に凸条５０を、小パッド１６に凹溝５２を、それぞれ設けたことにより、収容空間１８に小パッド１６を装着したときに、これらの凸条５０と凹溝５２とが嵌合して、小パッド１６の脱落を防止することができる。しかも、この凸条５０と凹溝５２は、小パッド１６の挿入方向に沿って設けてられているため、挿入時における障害にはならず、装着性が損なわれることはない。また、挿入時に小パッド１６を圧縮変形させなくても挿入することができるので、小パッド１６上面に接着した着座センサ１２の脱落や位置ズレの危険も回避できる。   Thus, by providing the convex space 50 in the accommodation space 18 and the concave groove 52 in the small pad 16, when the small pad 16 is mounted in the accommodation space 18, these convex stripe 50 and the concave groove 52 Can be fitted to prevent the small pad 16 from falling off. In addition, since the ridges 50 and the grooves 52 are provided along the insertion direction of the small pad 16, they do not become obstacles during insertion, and the mounting properties are not impaired. Further, since the small pad 16 can be inserted without being compressed and deformed at the time of insertion, it is possible to avoid the risk of the seating sensor 12 adhered to the upper surface of the small pad 16 being dropped or displaced.

また、本実施形態では、収容空間１８の左右一対の側壁２８，３０に凸条５０を設けて、上記嵌合により小バッド１６の左右両側を保持するようにしたので、小パッド１６の保持効果を高めることができる。   Further, in the present embodiment, the protrusions 50 are provided on the pair of left and right side walls 28, 30 of the accommodation space 18, and the left and right sides of the small pad 16 are held by the above-described fitting. Can be increased.

更に、本実施形態であると、収容空間１８の左右の側壁２８，３０に設けた凸条５０と、小パッド１６の左右の側面４２，４４に設けた凹溝５２との嵌合により、小パッド１６の前後方向における位置決めをすることができる。また、収容空間１８の前側の側壁２４に設けた凸条５０と、小パッド１６の前側の側面４０に設けた凹溝５２との嵌合により、小パッド１６の左右方向における位置決めをすることができる。即ち、パッド本体１４と小パッド１６は共に軟質フォームからなるため、このような凸条５０と凹溝５２との嵌合を設けずに、組付けた場合、収容空間１８の側壁や小パッド１６の側面が互いの摩擦で局部的な圧縮変形すること等によって、両者間で位置ズレが生じるおそれがあるが、本実施形態によれば上記嵌合によりこのような位置ズレを解消することができる。   Further, according to the present embodiment, the small ridges 50 are formed by fitting the ridges 50 provided on the left and right side walls 28 and 30 of the housing space 18 with the concave grooves 52 provided on the left and right side surfaces 42 and 44 of the small pad 16. The pad 16 can be positioned in the front-rear direction. Further, the small pad 16 can be positioned in the left-right direction by fitting the ridge 50 provided on the front side wall 24 of the housing space 18 with the concave groove 52 provided on the front side surface 40 of the small pad 16. it can. That is, since both the pad main body 14 and the small pad 16 are made of a flexible foam, when assembled without providing the fitting between the ridge 50 and the concave groove 52, the side wall of the housing space 18 and the small pad 16 are assembled. There is a possibility that a positional deviation occurs between the two sides due to local compression deformation caused by mutual friction. However, according to the present embodiment, such a positional deviation can be eliminated by the fitting. .

図５，６は、上記凸条５０及び凹溝５２の配置の変更例を示すものであり、図５の例では、収容空間１８の左右の側壁２８，３０のみに凸条５０を設け、前後の側壁２４，２６には凸条を設けていない。また、図６の例では、収容空間１８の前後の側壁２４，２６のみに凸条５０を設け、左右の側壁２８，３０には凸条を設けていない。小パッド１６側の凹溝５２は、収容空間１８の凸条５０に対応してそれぞれ設けられている。このように本発明において、凸条５０及び凹溝５２の配置は上記実施形態のものに限定されるものではない。また、凸条５０及び凹溝５２は、各側壁及び側面にそれぞれ複数本設けることが、小パッド１６の保持効果および位置決め効果を高める上で好ましいが、１本ずつ設けてもよい。また、上記ではパッド本体１４側に凸条５０を設け、小パッド１６側に凹溝５２を設ける構成としたが、逆に、パッド本体１４側に凹溝を設け、小パッド１６側にこれに嵌合する凸条を設けてもよい。   5 and 6 show a modification of the arrangement of the ridges 50 and the grooves 52. In the example of FIG. 5, the ridges 50 are provided only on the left and right side walls 28, 30 of the housing space 18, and The side walls 24 and 26 are not provided with ridges. In the example of FIG. 6, the ridges 50 are provided only on the front and rear side walls 24, 26 of the accommodation space 18, and no ridges are provided on the left and right side walls 28, 30. The concave grooves 52 on the small pad 16 side are respectively provided corresponding to the ridges 50 of the accommodation space 18. Thus, in this invention, arrangement | positioning of the protruding item | line 50 and the ditch | groove 52 is not limited to the thing of the said embodiment. Further, it is preferable to provide a plurality of ridges 50 and grooves 52 on each side wall and side surface in order to enhance the holding effect and positioning effect of the small pad 16, but one may be provided. In the above description, the protrusion 50 is provided on the pad body 14 side and the groove 52 is provided on the small pad 16 side. Conversely, the groove is provided on the pad body 14 side, and the groove 16 is provided on the small pad 16 side. You may provide the protrusion to fit.

なお、シートパッド１０は一般にその表面に編物や織物などの表皮が被せられ、更に金属フレーム上に載置することにより車両用シートとして構成されるが、本発明では特に、表皮をパッド表面に接着剤を用いて貼り合わせる表皮接着タイプのシートパッドに有効である。表皮接着タイプのシートパッドでは、表皮が薄く、そのため着座センサ１２をパッド内部に埋設しなければ、着座時に異物感を感じるためであり、本発明であれば、このような異物感を解消することができる。   In general, the seat pad 10 is covered with a skin such as a knitted fabric or a woven fabric on the surface, and further configured as a vehicle seat by placing it on a metal frame. In the present invention, the skin is particularly bonded to the pad surface. It is effective for a skin-adhesive type sheet pad to be bonded using an agent. In the case of the skin-adhesive type seat pad, the skin is thin, and therefore, if the seating sensor 12 is not embedded in the pad, a foreign body sensation is felt at the time of sitting. In the present invention, such a foreign body sensation is eliminated. Can do.
