Inner boot tongue of a ski boot
First Claim
Patent Images
1. 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.

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.
