  • Patent number: 11957623
    Abstract: Protective eyewear such as goggles (12) are provided with a frame (14) lens (20) and a pair of tabs (30) protruding from a front (32) of the lens (20) at lateral positions, to receive tear off sheets. The frame (14) includes lateral attachment formations (28) that can engage complemental attachment formations (46) on removable roll holders (34,36). Each roll holder (34,36) includes an anchor formation (50) with a recess (54) in which one of the tabs (30) is receivable. The roll holders (34,36) can be fitted on the attachment formations (28) and tabs (30) to use a roll-off system, or can be removed to use a tear off system. The frame (14) preferably has pivoting outriggers (22) which include the attachment formations (28), so that the roll holders (34,36) are attached to the outriggers (22) and can pivot off the lens (20) with the outriggers (22).

    Abstract: A helmet has an outer shell, an impact absorbing liner inside the outer shell to receive loads from the outer shell and an inner liner disposed inside the impact absorbing liner, with the inner liner configured to slide relative to the impact absorbing liner. The inner liner defines a number of apertures and a deflector inside each aperture. Each deflector has a body that is connectable to the impact absorbing liner; a peripheral border that is connectable to the aperture in which it is received; and a number of deformable spokes extending between the body and the border.
