Seat for a trolley, chair or the like

摘要

The seat (10) has a seat-surface (11) and swiveling backrest (12) the relative positions of which are coordinated. Displacement of the backrest causes the seat surface to slide along a preferably straight track in relation to the support frame. Part of the seat surface is movably mounted on preferably two parallel guides moving along base parts (15). At least part of the seat surface has preferably two rocker bearings (23). The seat is detachably connected by couplings, especially claws (17) to the support frame.
