Abstract

A saddle with a pneumatic suspension has a stiff skeleton (2) with a top seating layer, a hoop (1) and a pneumatic spring (3). A pneumatic damper (3) with at least one valve (31) is fitted inside the lower side of the skeleton (2) and a guiding element of at least one guiding mechanism (L) is fitted on the lower side of the skeleton (2). The skeleton (2) is slidingly linked and guided by the pneumatic damper (3) and the guiding mechanism (L) to a hoop (1). The middle part of the hoop (1) forms a supporting surface that rests against the lower elastic part of the casing of the pneumatic spring (3) and that is pressed inside the casing in its loaded state.

DECLARATION REFERRED TO IN ARTICLE 19

Claims 3 and 4 have been deleted. The arrangement of the pneumatically cushioned saddle according to claim 1 of patent application PCT / CZ95 / 00001 forms a new combination of the known elements which, with a connection with the description and the drawings, is different, simpler and more reliable than the arrangement of the spring mechanisms of the saddle the opposing writings (eg a smaller number of mutually movable parts guaranteeing a reliable guidance of the saddle against the frame) - This combination, in our opinion, is based on an inventive step, because it is not obvious to the skilled person from the prior art.

In the arrangement of the saddle according to claim 1, only a flat pneumatic spring (s all drawings) in the lower inner, so far not fully utilized space of the saddle skeleton is attached. In the subsidiary speeches, the sliding guide surfaces are cited as the spoken leadership elements, and these simple sliding guide elements are predominantly arranged also in the inner space of the saddle skeleton. A very simple and new resilient system is integrated in this way in the inner, previously unused space of the saddle skeleton, which is in contrast to the opposing writings in which a very complicated mechanism of the guide lever, metal springs and the complicated air springs is provided and only A saddle is fastened over this whole mechanism.
