<p>A padding element (6) for protection against shocks, particularly useful with a crash helmet (1), which confers on the helmet unusual adaptability to the user's head, comprises at least one deformable vesicle (7) containing a fluid (11) which, in use of the padding element, is a saturated vapor state, a Peltier-effect thermoelectronic component (16) having a face (17) in contact with a surface section of said at least one vesicle (7), and a power supply (19) for supplying an electric current in either directions to said component (16), so as to either develop or absorb heat from said face and adjust the vesicle (7) internal pressure.</p> |
