Patent number: 10765176Abstract: A buckle assembly for selectively connecting first and second straps of a personal protective device. The buckle assembly includes a receiver member and a latch member configured for coupling to a respective one of the straps. The receiver member defines a slot and provides a release arm. The latch member includes a latch tab pivotally connected to a base. In a latched state in which the latch member is disposed within the slot and a latch face is engaged with a capture surface. The release arm disposed over a portion of the latch tab. The latch face can be disengaged from the capture surface in response to an actuation force applied to the release arm. In some embodiments, the receiver member and the latch member incorporate various, complimentary guide surfaces that promote easy insertion of the latch member into the receiver member.Type: GrantFiled: May 12, 2015Date of Patent: September 8, 2020Assignee: 3M Innovative Properties CompanyInventors: David M.
