Abstract

A device for respiration with a half mask (4) and with a strap (6) for pressing the half mask (4) onto the face of a mask user (7). Wearing comfort is facilitated by providing the strap (6) of a one-piece cut made of an elastic material and having at least one four-point connection with straps (9, 10) to the half mask (4).

First claim

What is claimed is:

1. A device for respiration, the device comprising:
a mask body;
a strap for pressing said mask body onto the face of a mask body user, said strap being formed of a one-piece cut made of an elastic material and having at least one four-point strap to mask connection with four separate and spaced connection points connecting said strap to said mask body, said strap having a middle part and said at least one four-point strap to mask connection extending from said middle part, said middle part being arranged to press onto a back of a head of the mask body user while said mask body is pressed onto the face of the mask body user, said middle part and said four-point strap to mask connection being arranged so as to be cut from a single sheet of the elastic material as a single piece integral part, said strap having a strap fastening point formed by a fold in said single sheet of elastic material;
a hood adapted to cover said strap and a head of the wearer, said middle part of said strap having said strap fastening point connected to said hood on an inside of said hood, said strap fastening point being positioned spaced from said four-point strap to mask connection, said hood being formed of a supple material; and
a spacer present between said hood and said strap at said strap fastening point, said spacer being attached to and arranged at said fold in said single sheet of elastic material of said strap and to said hood to provide an insulating layer of air between said hood and said strap.

2. The device in accordance with claim 1 , wherein said four-point strap to mask connection comprises two upper straps and two lower straps;
said strap fastening point is arranged on said middle part between said two upper and lower straps.

3. The device in accordance with claim 2 , wherein:
said strap has a centerline arranged along a center of said strap;
said strap includes a neck closure, said two upper straps, said two lower straps and said neck closure separately extend laterally out from said centerline, and separately extend away from said middle part, said neck closure being spaced from said middle part and said straps.

4. The device in accordance with claim 1 , wherein outwardly extending straps defining sets of U-shaped straps extend from the middle part to said at least one four-point strap to mask connection;
one of said sets of U-shaped straps is arranged to be on a right side of the head of the wearer, one of said outwardly extending straps of said one set is arranged to be below an ear of the wearer, and another of said outwardly extending straps of said one set being arranged to be between the ear and eye of the wearer on the respective side;
said strap fastening point is arranged on said middle part between said U-shaped straps.

5. The device in accordance with claim 1 , wherein said spacer comprises an extension of a connection point of hood material of said hood.

6. The device in accordance with claim 1 , wherein said strap consists of an elastic textile material with an elongation of at least 120% in one direction and 300% in another direction.

7. The device in accordance with claim 1 , wherein said mask body is a half mask body or a full mask body.

8. The device in accordance with claim 1 , wherein:
said strap has a centerline arranged along a center of said strap;
said fastening point is located in an area of said centerline and between four points of said at least one four-point strap to mask connection.

9. A device for respiration, the device comprising:
a mask body;
a strap with a middle part for engaging a head of a wearer of the device and pressing said mask body onto a face of the wearer via four separate strap portions extending from the middle part and terminating in a four-point strap to mask connection, each of said four separate strap portions making a connection to said mask body at a point for a total of four points of connection, said four points of connection being separate and spaced from each other on said mask body, said strap being formed of a single sheet of elastic material with said middle part and said four separate strap portions being arranged so as to be cut from said single sheet of elastic material as a single piece integral part, said strap having a strap fastening location formed by a fold in said single sheet of elastic material;
a hood covering said strap, said hood including a hood fastening location on an inside of said hood and located spaced from said four-point strap to mask connection, said strap fastening location being arranged at said middle portion on said strap between said strap portions, and being spaced from said strap portions, said strap being connected to said hood through said hood and strap fastening locations, said hood being formed of a supple material; and
a spacer present between said hood and said strap at said hood and strap fastening locations, said spacer fastening said strap to said hood through said hood fastening locations, said spacer being located between said hood fastening location and said strap fastening location, said spacer being connected to said fold in said single sheet of said strap, said fold and said spacer being arranged to space said hood from said strap.

10. The device in accordance with claim 9 , wherein said four strap portions comprise two upper straps and two lower straps;
said strap fastening location is arranged directly between said upper straps and said lower straps, said hood fastening location being on a diametrically opposite side of said spacer than said strap fastening location.

11. The device in accordance with claim 9 , wherein said strap portions extend outwardly from said middle part and define two sets of U-shaped straps extending from the middle part to said four-point strap to mask connection;
one of said sets of U-shaped straps is arranged to be on a right side of the head of the wearer, one of said outwardly extending straps of said one set is arranged to be below an ear of the wearer, and another of said outwardly extending straps of said one set being arranged to be between the ear and eye of the wearer on the respective side;
said strap fastening location is arranged between said two sets of U-shaped straps.

12. The device in accordance with claim 9 , wherein said spacer comprises an extension of hood material of said hood.

13. The device in accordance with claim 9 , wherein said strap consists of an elastic textile material with an elongation of at least 120% in one direction and 300% in another direction.

14. The device in accordance with claim 9 , wherein:
said strap has a centerline arranged along a center of said strap;
said hood and strap fastening locations are located in an area of said centerline,
said strap includes a neck closure, said strap portions and said neck closure separately extend laterally out from said centerline, and separately extend away from said middle part, said neck closure being spaced from said middle part and said strap portions.

15. The device in accordance with claim 9 , wherein:
said strap and said half mask body are arranged to press said middle part onto a back of a head of the wearer, while pressing said mask body onto the face of the wearer.

16. A device for respiration, the device comprising:
a mask body;
a strap with a middle part for engaging a back of a head of a wearer of the device and four separately spaced strap portions extending from the middle part, each of said strap portions terminating in a strap to mask connection, each of said strap to mask connections being separate and spaced from each other o
