Abstract:
A chair having an outrigged limb rest for a seated working posture involving a laterally outstretched working arm, comprising:a seat extending between flanking lateral margins and spaced frontal and back margins, at least one of said lateral margins serves as a working side; a back rest disposed along the back margin; and an inboard rest structure disposed along the lateral margin of the working side, and comprising a given mounting structure supported by the chair at a lower portion and extending therefrom to an upper termination, in a crutch head, wherein either the given mounting structure or crutch head is adjustably supported by the chair, respectively, such that the crutch head can be moved between one of inboard and outboard extremes and one of upper and lower extremes in order that a seated occupant can adjust the crutch head under his or her armpit and thereby sag with all his or her weight on the crutch head and yet still be propped up in order to promote upright posture or alternatively dissuade posture that finds the seated occupant's spine leaning laterally over from a vertical axis; and an outrigged rest structure disposed along said same lateral margin and comprising an outrigger mounting structure and a limb rest supported thereby, said outrigged rest structure being adjustable to situate the limb rest in positions to support the occupant's working forearm while occupant's working upper arm is abducted to about the 4 to 3 o'clock position, or alternatively subtending about very approximately a 60Â° to 90Â° angle sweeping laterally up from straight down; whereby the crutch head acts to block the seated occupant's torso from leaning out as the limb rest acts to block the outstretched elbow from falling in, as from tiredness from lengthy periods of work as with the working hand substantially outstretched laterally away from occupant's hip or shoulder.
