<p>The invention relates to a sheet element (10) that has integrated therewith an alarm mat (2) and that is intended particularly for security containers and security spaces. The alarm mat (2) is comprised of light-conducting and/or current-conducting filaments or like devices. The alarm mat (2) includes a base mat (2a) and a supplemental mat (2b). The base mat (2a) has an essentially looped filament pattern of the kind, for instance, obtained with knitting or crocheting. The supplemental mat (2b) has a regular or irregular filament pattern. The base mat (2a) and the supplemental mat (2b) are tightly positioned together to form an alarm mat, wherewith the filament pattern of the base mat (2a) and the filament pattern of the supplemental mat (2b) deviate from totally coincidental overlap. The invention also relates to the use of the sheet element (10) as casing material in a container (20) or in a space intended for the storage of theft-attractive objects or the like.</p> |
