Abstract
Disclosed is a cross-strut arrangement for a folding roller-mounted chair having at least two struts connected to one another in a crosswise manner via a cross-strut articulation. The struts each are designed such that they can be changed in length, telescopically, for adjusting the seat width. At the top end of each strut a seat profile is located in the longitudinal direction of the folding roller-mounted chair and transverse to the strut for fixing the seat surface is adjustable to increase the seat depth. The cross-strut arrangement is comprised of the following features: each strut is made up of a top strut section and a bottom strut section, of which one telescopes in the other in a stepwise manner; each strut section has a row of holes corresponding to the other; a fastener which forms the cross-strut articulation is optionally fitted through a bore of one row of holes and, at the same time, through three further bores which are in alignment with said bore and belong to the other three rows of holes of the two struts; and the rows of holes are arranged such that the cross-strut articulation can always be fitted in the center of the crossover point.
