Abstract
The part of a boot in question, in particular an inner-boot tongue of a ski boot, is essentially constituted by an outer part (1) made of impermeable semi-rigid plastic having an alveolate structure (6), covered directly by a foam-type padding (4) and by a woven or knitted liner (5). The air contained in the alveoles of the alveolate structure forms a particularly effective damper cushion in dynamic compression.
Claims7
A ski boot containing an inner boot, said inner boot having a sole and an upper part and wherein said upper part has a padded part comprising;
- an outer part which is made of impermeable semi-rigid plastic;
- an alveolate structure on the inside of the outer part having alveoles hermetically closed on the outside by said outer part;
- a foam-padding lying directly on the open side of the alveoles, so that the alveoles are taken in sandwich between said outer part and the foam-padding;
- and an inner liner lying on the foam-padding, in such a manner that during dynamic compression of the padded part the foam penetrates further into the alveoles, compressing thereby the air trapped in said alveoles, so that instantaneous overpressures are damped.
