  • the diaphragm is arranged on the rear side of the corresponding reciprocating piston on a rear side, the diaphragm closes the large passage during compression in such a way that the damping is (especially) effective.
  • the membrane When removing or extending the damper, the membrane then opens the large passage in the reciprocating piston, so that the damping is not effective. If a reverse damping characteristic is desired, it is possible to turn the damper by 180 °.
  • the damping system can thus be adjusted and adjusted in a particularly simple and understandable manner for a driver, so that the driver can determine even his best setting, especially in racing. Factory settings are not required or can be changed. This may also be of interest, for example, in the case of abruptly changing conditions, such as, for example, during a temperature drop.

Abstract

Dans le cas de planches de glisse, notamment de skis, il convient de prévoir un bon compromis entre l'amortissement et la maîtrise. Différentes mesures peuvent être prises au niveau d'une interface entre une chaussure (ski) et la planche de glisse. La présente invention propose un système d'amortissement qui peut être supporté au niveau de la planche de glisse indépendamment d'un montage de la plaque de base en avant et/en arrière de la plaque de base soutenue et qui peut être adapté pour canaliser un flux de forces sur un chemin allant du point en avant et/ou en arrière de la plaque de base de la planche de glisse d'abord par l'intermédiaire de l'amortisseur puis jusque dans la plaque de base. Le ski peut ainsi être amorti de façon très efficace avec de bonnes caractéristiques de déplacement et il peut en option également fléchir de façon particulièrement libre, notamment grâce à un amortissement du ski indépendamment d'un mouvement relatif de la plaque de base. En outre, on peut également effectuer en option un réglage en hauteur, notamment par déplacement automatique du centre de gravité de l'utilisateur au moyen d'un guide coulissant. Le système de l'invention est également particulièrement bon pour la course.
