An improved operator's station (70) includes an improved three position seat assembly (90) which allows the operator (200) to stand, perch or sit while maintaining the operator's eyes at essentially the same vertical level (204, 206). The seat assembly includes a back rest (95), a seat (100) that may be raised and lowered, and a movable shelf (105) or perch positioned between the back rest and the seat. In a stand mode of operation, the seat is lowered and the shelf is raised; in a perch mode of operation, the shelf is lowered to provide a partial support for the weight of the operator, and, in a sit mode of operation, the seat is raised for substantially full support of the weight of the operator and the shelf is raised to be flush with the back rest. Two sets of foot pedals (120, 125; 130, 135) are provided in the improved operator's station (70). A first set of pedals (120, 125) is on the floor and includes a brake pedal (120) and a power pedal (125). These pedals are operated when the operator is either standing or perching. A second set of pedals (130, 135) is raised above the first set of pedals (120, 125) and positioned to be operated when the operator is in the seated position, although the operator may optionally also use one or the other of the raised pedals in either the stand or perch modes of operation, thus providing additional flexibility in operating positions.
L'invention concerne un poste de conduite amélioré (70) comprenant un ensemble siège amélioré à trois positions (90), qui permet au cariste de manutention (200) de se tenir debout, juché ou assis, tout en gardant le regard sensiblement au même niveau vertical (204, 206). L'ensemble siège comporte un dossier (95), un siège (100) pouvant être levé et baissé, et une tablette ou barre mobile (105) placée entre le dossier et le siège. En conduite debout, le cariste abaisse le siège et relève la tablette; en conduite juchée, il abaisse la tablette, sur laquelle il laisse reposer en partie le poids de son corps; et, en conduite assise, il soulève le siège pour laisser reposer sensiblement tout le poids de son corps et il relève la tablette pour l'aligner. Il existe deux séries de pédales (120, 125; 130, 135) dans le poste de conduite amélioré (70). Une première série (120, 125), au plancher, comprend une pédale de frein (120) et une pédale d'accélérateur (125), que le cariste utilise quand il est en position debout ou juchée. Une seconde série (130, 135), surélevée par rapport à la première (120, 125), est placée de manière à être utilisée depuis la position assise, mais le cariste peut éventuellement en utiliser aussi l'une ou l'autre lorsqu'il est en position debout ou juchée, ce qui permet une plus grande souplesse des positions de conduite.
