Abstract: The present invention relates to an impact protection device clip configured to locate an impact protection device about a post of a racking system. The post of such racking system includes a cross-sectional wall profile defining a chamber with an opening. The clip includes a body arranged in use to extend through said opening of the post. The body further includes first and second attachment devices for enabling attachment of the clip to the impact protection device, and at least one contact. The at least one contact is configured so that if the protection device is moved in a first direction causing a part of the protection device to be pulled generally away from the post, the contact engages against an inner face of the cross-sectional wall profile of the post so that the engagement between the contact of the clip and the post resists further movement of the protection device in the first direction.

Abstract: A face mask assembly (FMA) for supplying breathable gas to a wearer. The face mask assembly (FMA) includes a mask frame including a support, a facial cushion attached to the mask frame, and a forehead support. The forehead support includes a forehead cushion assembly and an adjustment knob operatively coupled to the forehead cushion assembly. The adjustment knob is threadably engaged with the forehead cushion assembly such that turning movement of the adjustment knob causes the mask frame to be moved between retracted and extended positions with respect to the forehead cushion assembly.
