Patent number: 11904191Abstract: A respirator that includes a harness and a mask body that is air permeable. The mask body has a sinus region and a primary filtering region and at least one nonwoven fibrous web. The sinus region of the mask body exhibits a resistance to airflow that is greater than the primary filtering region. This resistance to airflow is achieved through an alteration of the intrinsic structure of the plurality of nonwoven fibrous layers in the sinus region without adding additional material to the mask body. The alteration of the intrinsic structure assists in preventing eyewear fogging.Type: GrantFiled: June 23, 2021Date of Patent: February 20, 2024Assignee: 3M Innovative Properties CompanyInventors: John M. Facer, Audra A. Wilson, Christopher P. Henderson

Patent number: 8342180Abstract: A filtering face-piece respirator 10 that includes a mask body 12 and a harness 14. The mask body 12 contains a filtering structure 18 that is retained in position on the mask body 12 by a support structure 16 that includes a longitudinally-movable, centrally-spaced, transversely-extending member 26 that extends from a first side 22 of the structure 16 to a second side 24 without being joined together by any longitudinally-extending members that hinder movement of the transversely extending member 26 in the longitudinal direction. The transversely-extending members converge towards each other at east side 22, 24 of the mask body 12. A filtering face-piece respirator 10 of this construction can allow the mask body 12 to readily accommodate the motion of a person's jaw. Workers who use this filtering face-piece respirator may find it much easier to talk to other persons when working. A single mask size also may be able to properly fit to faces of various sizes.Type: GrantFiled: August 13, 2008Date of Patent: January 1, 2013Assignee: 3M Innovative Properties CompanyInventors: Philip G. Martin, Yonas Gebrewold, Daniel J. Stepan, Audra A. Wilson, Christopher P. Henderson, Thomas G. Skulley, Erik J. Johnson, Francesco Lovo, Dan Mattano, Claudio Ponzio

Patent number: 8104472Abstract: A respiratory mask (10) that comprises a mask body (12) and a harness (21) that includes a carriage (22) and a strap (24). The mask body (12) lacks a rigid insert, is non-elastomeric, and is adapted for fitting over a person's nose and mouth. The mask body (12) has a nose portion (14), a chin portion (16), first and second cheek portions (18 and 20), and an axis (32) that extends from the nose portion (14) to the chin portion (16). The mask body (12) is constructed to deform such that the first and second cheek portions (18 and 20) move towards each other about the axis (32). The carriage (22) is joined to the mask body (12), and the strap (24) is joined to the carriage (22) for supporting the mask body (12) over a person's nose and mouth. When tension is applied to the strap (24) and an opposing force acts at the nose and chin portions of the mask body, the first and second cheek portions (18, 20) exhibit movement about the axis (32) towards each other.Type: GrantFiled: March 26, 2004Date of Patent: January 31, 2012Assignee: 3M Innovative Properties CompanyInventors: Christopher P.

Publication number: 20080271740Abstract: A respirator 10 that has a mask body 12 that has a plurality of panels 16, 18, 20 that can fold in towards each other and that can unfold into open in-use configuration. At least one of the panels has a tab 22 that assists in opening the mask body 12 from its folded configuration into its open in-use configuration. The use of the tab 22 on the panel(s) of the multi-paneled mask body 12 allows for easier donning and doffing and reduces the opportunity for contaminants to get into the mask interior when the mask is being opened by the user.Type: ApplicationFiled: May 3, 2007Publication date: November 6, 2008Inventors: Nicholas J.

Patent number: 7077128Abstract: An eye-wear article (93) for use with a respiratory mask (1) comprises a flat piece of transparent polymeric material providing a visor portion. The flat piece of polymeric material has shaped portions in a lower edge that fit over respective selected parts of the mask, and elongate tabs (95) that extend from each side and are inserted into respective guides (97) on the head harness (7, 8) of the mask to cause the flat piece of polymeric material to adopt a curved configuration and locate the visor portion in front of the eyes of the wearer. The tabs (95) can slide in the guides (97) to permit the eye-wear article to be moved out of engagement with the mask and onto the top of the wearer's while the mask is being worn, without disturbing the position of the mask on the wearer's face and without affecting the respiratory protection provided by the mask.Type: GrantFiled: July 1, 2003Date of Patent: July 18, 2006Assignee: 3M Innovative Properties CompanyInventors: Audra A.
