【発明の属する技術分野】
この発明は、妊婦用パンツ、特に妊婦を「いい姿勢（ここで「いい姿勢」とは、母体にも胎児にとっても望ましい姿勢をいう。）」に保つ妊婦用パンツに関する。
【０００２】
【従来の技術】
従来、妊婦の腹部重心移動から生ずる腹筋の緊張を緩和し、腰仙部分を支えて腰痛を未然に防止するために、図６に示すように、後見頃形成部１００の上方中央部に上縁がガードルの上方開口部１０１を、下線が後中心線１０２に向かって斜降して、突出部分１０３をそれぞれ形成している横方向に伸縮する厚手のストレッチテープ片１０４よりなる腰部充当片１０５を配設し、この腰部充当片１０５を少なくとも人体の部分を囲繞する面積に形成したものがある（特許文献１参照）。
【０００３】
また、腰部が膨張する妊婦に好適に着用されるようにするために、図７に示すように、丸編機で円筒状に連続編成した編み地を用い、この編み地は部分的に編み方を変えており、腹部に当たる部分１１１を略半円状に区画して、この区画部１１１に立体的な膨らみを持たせるとともに、伸びの大きな編組織とする一方、各左右膨出部１１３、１１４のそれぞれを囲んで伸びの小さい編組織１１５、１１６を設けたものがある（特許文献２参照）。

【０００６】
【発明が解決しようとする課題】
一般に、妊婦が妊娠中期以降になると、図５に示すように、腹部が前方に膨出するとともに、腹壁が増大し、腰椎の前彎度が大きくなる。そのため妊娠子宮が恥骨上縁で前に突出するようになり、母体にも、胎児にも好ましくない。そのため、妊娠中期以降は、腰椎の前彎度が大きくなるのを防ぐようにしなければならない。上記した特許文献１、特許文献２の下着等では、腰痛防止、腹部に負担がかからないようにするという効果は認められるものの、腰椎の前彎度を小さく保持するとの観点で考案されたものではなく、着用しても腰椎の前彎度を小さくするという効果は得られなかった。
【０００７】
この発明は上記問題点に着目してなされたものであって、妊娠の中期以降においても、妊婦の姿勢が好ましくない姿勢に変化するのを防止し得る妊婦用パンツを提供することを目的とする。
【０００８】
【課題を解決するための手段】
この発明の妊婦用パンツは、左右上下に伸縮自在に形成した略半円状の腹部保持部と、この腹部保持部の下部に縫着され、前見頃から後見頃に延設されてなる下腹支持部と、この下腹支持部の下部に縫着されるヒップ持ち上げ部と、このヒップ持ち上げ部の前方下部から後方下部に形成されるクロッチ部とからなり、前記下腹支持部に対し、前記腹部保持部の伸縮性を大きくするとともに、前記下腹支持部の前方下端と前記クロッチ部前端までを７．２５〜８．２５ｃｍの寸法に形成している。
【０００９】
この発明の妊婦用パンツにおいて、下腹支持部と腹部保持部の伸縮性は１：２の比率になるようにすると良い。
【００１０】
また、この発明の妊婦用パンツにおいて、前記下腹支持部の前方下端は、前記下部支持部を介して、前記クロッチ部前端に連接すると良い。
【００１１】
また、この発明の妊婦用パンツにおいて、前記下腹支持部の前方下端と前記クロッチ部前端までの寸法を好ましくは７．５ｃｍ、前記下腹支持部の前方下端と前記ヒップ持ち上げ部の前方上端間の寸法を好ましくは４．５ｃｍに形成すると良い。
【００１２】
【発明の実施の形態】
以下、実施の形態により、この発明をさらに詳細に説明する。図１は、この発明の一実施形態である妊婦用パンツの正面図、図２は同妊婦用パンツの側面図である。この実施形態妊婦用パンツ１は、上部開口部２の前端２ａから下方に向けて配置形成される略半円形状の腹部保持部３と、この腹部保持部３の側端及び下端と縫着され、上部開口２の右端２ｂと左端２ｃより、腹部保持部３の下端方向に向けて配置形成される下腹支持部４と、後身頃より、前記下腹支持部４の下端部に沿ってリング状に形成され、上部側端及び上部前端が、前記下腹支持部４の下部側端及び下部前端に縫着されてなるヒップ持ち上げ部５と、前記ヒップ持ち上げ部５の下部前端と下部後端間に連設され、自身の非縫着部とヒップ持ち上げ部５の下端中央部分の非縫着部とで、脚挿入用の下部開口部７、８を形成するクロッチ部６と、上部開口部２の後端２ｄと、腹部保持部３の右後端、左後端と、ヒップ持ち上げ部５の上部後端間に縫着して配置形成される背腰保持部９とから構成されている。
【００１３】
腹部保持部３は、縦横に伸縮性を有する２Ｗａｙカバー部分３ａと、サポート部３ｂを有する。カバー部分３ａは、ナイロン３０ｄ（デニール）；８５％、ポリウレタン２０ｄ；１５％の布地であり、サポート部分３ｂは、同じくナイロン３０ｄ；８５％、ポリウレタン２０ｄ；１５％の布地に、ストレッチレース構成のものである。
【００１４】
下腹保持部４は、ポリエステル７５ｄ；６４％、ベンベルグ４０ｄ；１９％、ポリウレタン２１ｄ；１７％の生地を２枚重ねしたものを使用しており、伸び率低く、強度の大な安定部分を構成している。腹部保持部３と下腹支持部４の伸び率の度合いは約２：１となるように設定している。
【００１５】
ヒップ持ち上げ部５は、下腹支持部４と同素材の布１枚を使用している。クロッチ部６は通気性の良い網目状の素材を使用している。素材自体は、ヒップ持ち上げ部５等と同様のものを用いれば良い。
【００１６】
背腰保持部９は、伸展のないクッション性のある素材であるポリエステル１００％、Ｗラッシェルで腰部の伸びを止めるようにしている。
