Definitions

  • the invention relates to an arrangement for detachable connection of a respirator with a protective helmet by means of a both sides mounted detachable and variable-length bracket.
  • From DE 103 14 136 B3 is a holding device for respirators, which are not held by a harness directly to the head of the user, but connected via a special bracket directly to the helmet worn by the user on the head and can be solved by this again, are known.
  • the detachable attachment of the respirator directly to the protective helmet ensures a quick application or removal of the respirator without having to remove the protective helmet from the head, and reduces the burden on the user during use.

  • the invention has for its object to provide a simple design holding device for releasably connecting a respirator with a protective helmet, which with the helmet attached, regardless of the user's head shape a simple and secure application and a comfortable and dense fit of the mask on the face User ensured even under extreme conditions and is also designed compact.
  • the core of the invention is the formation of the detachable holder between the respirator and protective helmet as a two-sided, rotatable at the connection points of the holding elements four-point suspension.
  • the rotatable coupling of the holding Elements of the helmet and mask is realized either by hinges or by a pliable design of the holding elements or an end portion lying at the coupling point of the holding elements.
  • the position of the rotatable coupling points near the pivot point of the protective helmet on the head is achieved by the close juxtaposition of the rotatable coupling points provided on the respirator on the right and left side. That is, due to the V-shaped arrangement of the holding elements are their coupling points on the helmet near the pivot point of the helmet around the head of the user.
  • the rotatable coupling points of the holding elements on the protective helmet can still be arranged offset to each other, in such a way that the upper rotatable coupling point has a smaller distance to the respirator than the lower rotatable coupling - Point.
  • the respirator is independent of the respective head shape and - even under extreme conditions and the relative movement between helmet and head of the user uniformly and safely sealing both the forehead and in the chin area held on the user's face.
  • the rotational mobility at the coupling point is determined by a substantially rigid retaining element fixed in pivots or by a end attached but as a whole or at least reaches the slippery holding element at the end sections.
  • a combination of pivotable and slidably rotatable coupling on one side and the other side of the relevant holding element or of the upper or the lower holding element is also conceivable.
  • the holding elements can also be rotatably mounted inside or outside of the helmet shell in the manner described above.
  • the respirator can be easily and quickly applied or removed.
  • it is also conceivable to make the connection between the mask and the helmet by attaching the retaining elements attached to the helmet to a fastening element formed on the respiratory mask.
  • the helmet-side upper rotatable coupling point is arranged closer to the pivot point of the protective helmet than the helmet-side lower rotatable coupling point.
  • the helm-side ends of the holding elements via the rotatable coupling points are each attached to a common kausj och, to maintain the predetermined coupling points of the holding elements on the helmet even with different load on the holding elements, twistable, but releasable, each in a helmet trained, provided with recesses fastener is suspended.
  • An abstrebendes from the connecting yoke fastening part can also be against rotation on the helmet - guided - be suspended.

Abstract

L'invention concerne un support pour relier de manière libérable un masque (6) de protection respiratoire à un casque de protection (1), le support comportant sur chacun de ses côtés deux éléments de retenue (8, 10) séparés, l'un situé au-dessus et l'autre situé en dessous du point de rotation (14) du casque de protection, tous deux ajustables en longueur, qui s'écartent l'un de l'autre en forme de V entre le masque de protection respiratoire et le casque de protection et dont les extrémités sont articulées sur le casque de protection par l'intermédiaire d'un point supérieur et d'un point inférieur d'accouplement (7, 9) mobiles en rotation et sur le masque par l'intermédiaire d'un point supérieur et d'un point inférieur d'accouplement (13, 15) mobiles en rotation réalisés soit par des articulations rotatives soit par une configuration flexible de l'élément de retenue. L'élément inférieur de retenue s'étend essentiellement à l'horizontale et l'élément supérieur de retenue s'étend obliquement vers le haut de sorte que tant la zone du menton que la partie frontale du masque de protection respiratoire peuvent être repoussées séparément contre le visage de l'utilisateur. Le point supérieur d'accouplement côté casque est situé plus près du point de rotation (14) que le point inférieur d'accouplement mobile en rotation. L'assise du masque reste essentiellement inchangée même en cas de déplacement du casque. Les éléments de retenue sont fixés sur le casque de protection par une entretoise de liaison (3) qui peut être suspendue sur le casque sans pouvoir tourner et sur le masque par une pièce (12) de raccordement du masque.
