Problems solved by technology

As a result it has only minor damping properties or is difficult to use
Especially air filled cushions have the problem that when the cover is damaged the air escapes and the shock absorbing properties are lost

Embodiment Construction

[0014] A mat 1 selected as an example includes an outer shell 2 and a core 3 . A layer 4 is arranged between the jacket 2 and the core 3 . The cushion 1 is provided with a valve 5 , which passes through the outer shell 2 and the layer 4 and thus projects into the core 3 . This valve 5 is provided with a mouth for inflation. In a variant of this embodiment, the valve 5 can also be designed as a non-return valve.

[0015] In this exemplary embodiment, the jacket 2 is configured as a breathable structure. It can expand so as to be able to comply with changes in shape caused by loads and by inflation of the cushion. The core 3 and layer 4 consist of at least one filler material. The filler materials have different hardnesses. In this embodiment, the filling material for layer 4 is solid silicone; the filling material for core 3 is foamed silicone. The foamed silicone of the core 3 contains air inclusions, which are indicated with "6" in the figures.

Abstract

A cushion (1) having damping properties for use in bicycle pants includes an outer shell (2) and a core (3) therewithin surrounded by at least one layer (4) arranged between the outer shell (2) and the core (3). The core (3) and the layers (4) are formed by at least one filler material having different degrees of firmness. A valve (5) is provided in the outer shell to control the passage of air to and from the core (3) and interior cavity. The damping properties of the cushion (1) can be changed by inflating or deflating the core (3) with air.

Description

technical field [0001] The invention relates to a cushion for bicycle trousers having shock-absorbing properties, comprising an outer shell and a core and at least one layer arranged between the outer shell and the core. Background technique [0002] Cushions with shock-absorbing properties are familiar in a variety of ways. In the simplest form, these cushions consist of a foam padding which is surrounded by textile or plastic. The cushions are generally used for seat cushions. Furthermore, simple air cushions are known, which are produced solely from an airtight outer shell and in which the damping is effected by the enclosed air. The inflatable cushion can be arranged in an object to be upholstered, such as a seating surface or the like. Air cushions that can be inflated are also used as thermal insulation in clothing. [0003] The aforementioned mats are simple in construction in their construction. As a result, they have only low damping properties or are difficult...
