Abstract: A screen includes a frame and a panel coupled to the frame. The frame includes a first frame member having a first longitudinal axis, a first opening extending therethrough along the first longitudinal axis, and an aperture extending along an axis that intersects the first longitudinal axis, a second frame member having a second longitudinal axis and a second opening extending therethrough along the second longitudinal axis, and a connecting member coupled between the first frame member and the second frame member. The connecting member has a first portion that is received within the first opening and having a plate movable via a fastener to clamp the plate against the first frame member. The first fastener is accessible through the aperture. The connecting member also includes a second portion that is received in the second opening.

Abstract: Earphones which attach to an interior of a helmet are disclosed. Physical attachment of the earphones to the helmet result in an electrical connection in some embodiments. The headphones may be used without the helmet through the use of strap holder adapters in some embodiments.

Abstract: A helmet assembly includes a face shield and a single, center top mounting arrangement that operatively connects a center top location of the face shield to a center front mount on the helmet. The face shield can be raised and lowered about a pivot axis provided in the mounting arrangement between a tilted up, non-use position and a lowered, deployed position. The mounting arrangement can include a detent and two recesses, wherein the detent engages a first recess at a slightly forwardly displaced position to allow ventilation between the helmet and mandible and the face shield and a second recess at the tilted up, non-use position. The recess and detent engagement can be overcome by easy manual force acting on the face shield to reposition the face shield.

Abstract: A helmet attachment system is usable to attach a mandible or face or mouth guard. The helmet attachment system also comprises a pair of attachment bases, each arranged on a side of the helmet near to an ear covering of the helmet. The attachment bases each include a metal base plate covered by an attached body block. Each attachment base provides provisions for attaching opposite ends of a mandible to the bases. The metal base plate includes hooks for engaging an edge of the helmet. A pair of strap assemblies is provided, each strap assembly connected to one attachment base. The strap assemblies extend rearward and are connected to the back rail by a buckle member on the end of each strap assembly. The back rail includes a pair of buckle member-receiving slots. The straps assemblies and the hooks provided on the attachment bases secure the attachment bases to the helmet.

Abstract: A helmet assembly is provided including a front mount configured to attach to the front of the helmet above a brim of the helmet, a mandible for protecting a portion of the user's face, a lower edge rim mounting portion such as a halo attached along the lower edge of the helmet for securing the mandible to a helmet and providing power and data conduits. The front mount provides a center top mounting arrangement that operatively connects a center top location of the face shield to a center front mount on the helmet. The mount provides frontal bracket portions for mounting accessories. The helmet assembly provides a helmet shell with a curved shape having a surrounding reinforcing ridge. A reeling system is provided for adjusting front and lower chin straps. Other improvements in helmet assemblies are also disclosed.

Abstract: Methods and devices for adjusting the position of a mandible guard relative to a helmet are disclosed. Adjustment of the mandible guard may be performed by a user while the user is wearing the helmet and/or without the use of tools. A mandible guard adjustment system may be combined with an attachment system for attaching and removing the mandible guard to a helmet.

Abstract: A helmet attachment system is usable to attach a mandible or face or mouth guard. The helmet attachment system can attach other articles such as goggle straps and night vision devices. The helmet assembly includes a front rail that is substantially contiguous with side rails mounted to the helmet which extend rearward to be substantially contiguous with a back rail mounted on the helmet. The side rails are configured to provide attachment locations for further components, such as lights, electronics, communication equipment, etc.
