前記突起は、1または複数の突起群を形成し、前記突起群は前記メンブレンの複数の局部領域に配置されている、シールクッション。 - 前記突起の高さは前記メンブレンの厚さの少なくとも2倍である、請求項1に記載のシールクッション。
- 前記突起の幅及又は長さの少なくとも1つは前記メンブレンの厚さの少なくとも2倍である、請求項1又は請求項2に記載のシールクッション。
- 突起群内の前記突起は規則的に配置されている、請求項1〜3のいずれか1項に記載のシールクッション。
- 2以上の突起群が、少なくとも係合前又は係合後に異なるレベルの弾性又は変形抵抗の少なくとも1つを与えるように適合された、請求項1〜4の何れか1項に記載のシールクッション。
- 前記メンブレンは、前記シールクッションが患者の顔に係合したときに患者の鼻梁に隣接する鼻梁領域と、前記シールクッションが患者の顔に係合したときに患者の鼻孔に隣接する鼻孔領域と、を有し、前記鼻梁領域及び前記鼻孔領域には1以上の突起群が位置し、前記鼻梁領域に位置する突起群は、前記鼻孔領域に位置する突起群よりも長い請求項1〜請求項5のいずれか1項に記載のシールクッション。
- 突起群は、鼻梁領域の両側又は、鼻マスクの鼻孔に隣接する前記メンブレンの下隅又はフルフェイス型マスクの前記口に隣接する側の少なくとも1つに位置する、請求項1〜請求項6のいずれか1項に記載のシールクッション。
- 前記シールクッションの実質的な中央垂直軸を横切って対向する突起群の1以上のペアは、実質的に同一の全体形状を有する、請求項1〜請求項7のいずれか1項に記載のシールクッション。
- 1以上の前記突起は、開口を画定するメンブレンの内側端部に向かって前記突起の幅又は高さの少なくとも1つが減少するように前記突起の長さ方向に沿ってテーパが付いている、請求項1〜請求項8のいずれか1項に記載のシールクッション。
- 前記突起が弾性又は変形抵抗の少なくとも1つの大きい領域と小さい領域との間で段階的に遷移するように、前記突起の1以上には外端に向かって突起の高さまたは幅が縮小するテーパが前記突起の長さ方向に交差する方向に付いている、請求項1〜請求項9のいずれか1項に記載のシールクッション。
- 前記突起のそれぞれは、使用時に前記メンブレンが変形した構成において、隣接する突起の対応する当接面に当接させられる当接面を備える、請求項1〜請求項10のいずれか1項に記載のシールクッション。
- 1以上の前記当接面は、隣接当接面と係合しているときに横方向移動又は滑りに抵抗するように適合されている、請求項11に記載のシールクッション。

- 前記メンブレンは接触面領域において断面が湾曲しており、曲率が患者の顔への係合による変形で増大した所では、前記メンブレンの曲率の増大により隣接突起間の係合が生じる、請求項1〜請求項15のいずれか1項に記載のシールクッション。
- 前記メンブレンは下に支持部材又はクッションの少なくとも1つを持たず、前記メンブレンと付属する突起によってのみ変形抵抗が与えられる、請求項1〜請求項16のいずれか1項に記載のシールクッション。
