Abstract: Supporting spring systems for sleeping, reclining or sitting furniture must have spring characteristics that provide good sleeping, reclining and/or sitting comfort. In known supporting spring systems, this is achieved only by relatively high design expenditure. The invention aims to create a simple and flexible supporting spring system which nevertheless ensures high sleeping, reclining or sitting comfort. Support elements (13, 50, 60, 70, 80) for connecting two female connectors (10) of a pair of female connectors (11) are provided for this purpose. The support elements (13, 50, 60, 70, 80) exhibit spring arms (15, 72) that are guided from beneath the female connectors (10) of the pairs of female connectors (11) up around the outside of the pair of female connectors (11).

Abstract: An ophthalmologic examination unit comprises a chin rest (31) and a plurality of examination instruments (30, 59, 60) whose position can be laterally adjusted relative to the patient's eyes to be examined and which can be adjusted in elevation. The chin rest (31) and the instruments (30, 59, 60) are attached to a common supporting element (13) which can be vertically adjusted by means of a drive unit (18), such that the examination procedure be rendered as simple and convenient as possible and that the instrument setting be facilitated.

Abstract: An examination unit which is particularly suitable as an ophthalmologic examination unit for the examination of a patient by an ophthalmologist, comprises a storage region for an examination apparatus, wherein the storage region is defined by a wall, and an opening in the wall for passing the examination apparatus therethrough from the storage region. In order to ensure an easy transfer of the examination unit to the patient a support frame is provided in the storage region having a pivot bearing with a pivot axis. A swivel arm is pivotable around the pivot axis from a rest position in which the swivel arm is positioned within the storage region, into an operating position in which the swivel arm has the free end thereof laterally swung out of the storage region through the opening. Furthermore, the examination apparatus is suspended at the free end of the swivel arm.
