"Footwear, especially ski boots"

The invention relates to footwear, in particular a ski boot, with an inflatable cover inserted between the inner and outer layers Outer socket,

Such footwear is described in the main patent, at ^:::

the one inflatable cover in combination with other closing %

devices for the ski boot for the final bracing;

and ensures that the foot is held in the shoe. '

It has already been described that the pneumatic casing except- %

which is equipped with elastic and cold-insulating fillers %

can be and that a combination of air with solid or i

liquid substances is also possible. %

This measure according to the main patent is now according to the invention ^

further developed in that a honeycomb 3,

like foam rubber is inserted. ';' ■

Foam rubber is understood to mean a honeycomb-like structure, ||

on the other hand has strongly receding areas. Through this additional tensioning body should have a static elasticity of the entire envelope and thereby a certain pre-tension of the Can already be reached by foot.

The foam rubber can, for example, from oven-cell foam, if appropriate consist of small canals. It is also possible to use a combination of the honeycomb-like construction to produce open-cell and closed-cell foam. the Foaming can be done in situ.

The cover provided with the honeycomb-like insert can preferably be used as a counter-bearing for a ski boot known per se buckles attached over the heel may be provided.

It is best if the casing extends from the edge of the shaft to the level of the root of the toes, that is to the point where the balls of the feet are located on the one hand, on the other hand, extends over the ankles.

An example embodiment of the invention will now be explained in more detail with reference to the accompanying drawing, in the

FIG. 2 shows such a ski boot in a view, FIG. 1

shows in partial section.

Between the outer shaft 1 and the inner shaft 1 is corresponding to Proposal of the main application an inflatable shell 2 inserted, which according to this embodiment an open-cell honeycomb-like Insert 3 carries. A valve 5 with a molded valve protector is attached at a point where there is damage of the valve is not to be expected. The rigid cap 6 leaves the toes free of movement, since according to this embodiment the Pneumatic sheath with insert from the shaft edge only extends to the level of the toe root. With 7 is the (dashed line) Course of the pneumatic sheath over the ankle, ankle and

Ball up to the root of the toes indicated "

The overall course or the overall extent of the envelopes is shown in dashed lines at 8 in Figure 2 (view), i.e. the Course from the toe root over the instep and ball of the foot and the ankle to the heel, a heel pad 9 is in the counter bearing intended. This can be inflatable or as a vacuum chamber Equalization valve designed against the atmosphere. Buckle toes, known per se, are provided for an accurate To facilitate tensioning of the shoe in the counter bearing. The valve labeled 5 above is labeled 11 here.

The air envelope presses the shoe from the instep (front sheet) against the tensionable heel piece (rear part of the shaft) the padding wedge in the heel area,

Compared to the pure filling with air, there is a certain stabilization, as the elasti + when the air cushion is evaded see honeycomb construction has a braking effect; the air requirement is reduced, so the evasive action is "slowed down" when the load is applied and thus more controlled.
