Abstract
A three-point bridge suspension end bearing for transverse slats in a bed underframe includes a central spring element arranged centrally between two elastic bridge elements having eyes in their lower part. The eyes are rotatable about the axis of journals fixed to the underframe. The central spring element can be supported by a fixed or by a mobile support. Adjacent bridge elements can share the mount journals in a hinge-like partition of the rotatable eyes. Transverse slat caps can be incorporated in the top parts of the bridge elements with transverse connections to the central spring element or to the central spring element formed from bow-shaped segments. Transverse connections in collaboration with the bridge elements, or the tube chamber of a pneumatic sprung surface bearing, or a flexible/elastic belt, can be used as a mobile support, thus interactively coupling the three-point suspension end bearings.
