JACKS AND DENTIST'S OR OTHER CHAIRS

摘要

A dentist's or other chair has a reclining mechanism interlinking the back rest (36), the chair seat (34) and a leg or foot rest (38) for raising and reclining the back rest (36), for tilting the chair seat (34), and for lowering and raising the leg or foot rest (38) together. In order to be able to recline the chair so that its seat (34), back rest (36) and leg or foot rest (38) are both flat and horizontal, the mechanism includes means for disengaging the chair seat so that with the chair seat disengaged and horizontal, the back rest (36) can be reclined and the leg or foot rest (38) can be raised both also to horizontal.
