Title: (DE) DRUCKENTLASTENDES KISSEN
(EN) PRESSURE RELIEVING CUSHION
(FR) POCHE POUR SOULAGER LA PRESSION SUR LE COCCYX
Abstract:
(EN) There is provided a gas containing sac suitable for use in or as a pressure relieving cushion and including an inflatable structure having at least front and rear portions, and support regions for supporting the ischial tuberosites and coccyx of a user, gas in the sac being displaceable so that the action of a user sitting on the sac can cause (i) the front and rear portions to be inflated by displaced gas and (ii) the support regions to be suspended from the sac, wherein the inflated front portion causes the pelvis of the user to rotate rearwards and the inflated rear portion provides support behind the coccyx of the user.
(FR) L’invention concerne une poche contenant du gaz, à utiliser dans un coussin destiné à soulager la pression ou en tant que coussin, et comprenant une structure gonflable comportant au moins des partiesavant et arrière, et des régions de support permettant de supporter les tubérosités ischiatiques et le coccyx de l’utilisateur, le gaz contenu dans la poche pouvant être déplacé de sorte que l’action de l’utilisateur qui s’assoit sur la poche peut entraîner (i) le gonflement des parties avant et arrière en déplaçant le gaz et (ii) la suspension à partir de la poche des régions de support, auquel cas la partie gonflée avant fait pivoter le pelvis de l’utilisateur vers l’arrière et la partie gonflée arrière fournit un support derrière le coccyx de l’utilisateur.
