A springy seat retainer assembly for a bicycle comprises three sections, namely a seat post member (20) to be entered and clamped in a seat tube, further a movable intermediate section (3, 4), and a seat attachment part (2) having attachment details for a conventional saddle. The intermediate section comprises substantially parallel bars (3, 4) each being journalled both on the upper portion of the seat post member (20) and on the seat attachment part (2), as well as a springing mechanism mounted in between two diagonally placed bearings (23, 28) to push the seat attachment part (2) upwards. When the rear wheel receives a shock, a very good compensating cushioning movement directed obliquely downwards and backwards is obtained.

L'invention concerne un ensemble de retenue de selle à ressorts pour une bicyclette. Cet ensemble comprend trois parties, à savoir, un élément (20) formant montant de selle à insérer et fixer par serrage dans un tube de selle, une autre partie intermédiaire mobile (3, 4) et une pièce (2) de fixation de selle comportant des dispositifs de fixation pour une selle classique. La partie intermédiaire se compose de barres sensiblement parallèles (3, 4) chacune tourillonnée tant sur la partie supérieure de l'organe formant montant de selle (20) que sur la pièce (2) de fixation de selle, ainsi que d'un mécanisme de ressort fixé entre deux paliers (23, 28) orientés dans le sens diagonal, de manière à pousser la pièce de fixation (2) de la selle vers le haut. En cas de choc sur la roue arrière, on obtient un très bon mouvement d'amortissement de compensation dirigé, dans un sens oblique, vers le bas et vers l'arrière.
