Embodiment Construction

[0068] figure 1 The shown sealing cushion arrangement 1 comprises a sealing lip 3 which, in the application position, fits onto the surface 2 of the face shown here.

[0069] The mask cushion arrangement 1 also comprises a cross-sectional thickening 4 which, in the present embodiment, is arranged between the upper peripheral edge 5 and the sealing lip 3 .

[0070] The cross-sectional thickening 4 is configured such that the Shore hardness of the material forming the cross-sectional thickening varies. The region of material represented here has an almost jelly-like character. The innermost material region 6 has a lower Shore hardness than the adjacent material region 7 , which in turn has a lower Shore hardness than the adjacent material region 8 . The outer region of the cross-sectional thickening is made of a substantially fully cross-linked elastomeric material and has substantially the same Shore hardness as the sealing lip 3 .

[0071] The different material properties ...

Abstract

The invention relates to mask cushioning for a respiratory mask, a respiratory mask, and method for producting the same. The aim of the invention is to provide air-tight cushioning for a respiratory mask, in addition to a respiratory mask that is characterised by a sufficiently good air-tight action and is extremely comfortable to wear. This is achieved by a mask cushioning device for a respiratory mask, comprising a receiving opening, which corresponds at least to the nose and / or mouth region of a mask user, when the mask is worn and comprising a sealing lip that is configured from an elastomer material, surrounds the receiving opening and rests on the surface of the face of the mask wearer. The mask cushioning is characterised in that zones with an increased cross-section are configuredin the mask cushioning and that the mask cushioning material in said zones has different material properties in such a way that the shore hardness of the mask cushioning in the border region is higher than that in the core region or at least close to said region. The invention also relates to a respiratory mask equipped with a corresponding mask cushioning device, in addition to a method and a mould for producing the same.

Description

[0001] This application is an invention patent application titled "Mask liner and forehead liner for respiratory mask, respiratory mask, and molding tool and method for manufacturing the mask", with an application date of June 16, 2003 and application number 03813817.4 divisional application. technical field [0002] The present invention relates to a mask liner and forehead liner for a respirator, the respirator itself, and molding tools and methods for making such a respirator. In particular, the invention relates to a mask liner and a breathing mask equipped with that mask liner, by means of which mask liner the inner space formed by the breathing mask and the surface of the face of the user of the mask is sealed from the surrounding atmosphere Closed so that at least in a phase-wise manner an increased pressure relative to the surrounding pressure can be built up in the interior of the breathing mask. Such breathing masks can be used in particular for the medical or thera...
