<p>The present invention generally relates to a retention system that could be used to install in the internal surface of face-shields (7), for example of motorcycle helmet's visors, several devices, like screens working as solar filters, anti-glare screens, antifog screens, anti-scratch screens or different types of screens or devices, without alter or modify the characteristics of the visor (10) on which they are applied. The screen and the visor itself are this way preserved from damages, alterations and/or early substitutions. Such a system is constituted by at least one screen (1) and at least one gasket (2) with adhesive characteristics that can make such screens removable and re- positionable. This system can be created exploiting the characteristics of some materials.</p> |
