A stationarily-mounted seating structure consists of a pair of spaced supports, a seat pivotably mounted between the spaced supports and a back fixed to the spaced supports. Each spaced support includes forward and rearward vertical support members and the seat is mounted to the forward vertical support member while the back is mounted to the rearward vertical support member. A pivot mechanism for pivotably mounting the seat between the supports includes a shaft extending between and connecting the forward vertical support members. A stop element is fixed on the shaft for limiting the range of pivotable movement of the seat. A bushing is secured to the seat and is formed with an inner bearing surface for rotatably supporting the shaft, and outer bearing surfaces for engaging the stop element as well as a shroud which conceals the stop element, the bushing and a portion of the shaft. A foot bracket is mounted to each end of the shaft, and a platform bracket is mounted to the forward vertical support member. A threaded fastener secures the foot bracket to the platform bracket, and a slot in the foot bracket enables adjacent foot brackets to be placed at an angle to each other for use in a radiused installation.

Chaise à montage fixe constituée d'une paire de supports espacés, d'un siège pivotant monté entre les supports espacés et d'un dossier fixé aux mêmes supports. Chaque support espacé comprend des éléments de support verticaux avant et arrière. Le siège est fixé à l'élément de support vertical avant et le dossier, à l'élément de support vertical arrière. Un mécanisme de pivot, pour fixer le siège de façon pivotante entre les supports, comporte un arbre placé entre et reliant les éléments de support verticaux avant. Une butée est montée sur l'arbre pour limiter l'étendue de la rotation du siège sur l'arbre. Une bague est fixée au siège et comporte une surface d'appui interne pour soutenir l'arbre de façon pivotante et des surfaces d'appui externes pour engager la butée ainsi qu'un élément de recouvrement qui dissimule la butée, la bague et une partie de l'arbre. Un support sur piétement est monté à chaque extrémité de l'arbre, et un support à plate-forme est monté aux éléments de support verticaux avant. Un élément de fixation fileté fixe le support sur piétement au support à plate-forme. Un trou oblong dans le support sur piétement permet aux supports sur piétement adjacents d'être placés à un certain angle les uns par rapport aux autres pour les montages en arc de cercle.
