Abstract: The spring bridge (2) includes a main, load-bearing bridge (6), which can be fitted in the frame of a mattress base, and one or more supporting elements (8) arranged thereon. The supporting elements (8) extend, preferably in the form of a sheet-like, wing-like lip, from the main, load-bearing bridge (6), in the lateral direction, transversely with respect to the longitudinal axis of the main, load-bearing bridge and project beyond the top side of the main, load-bearing bridge (6). They are designed such that their flexibility in relation to the main, load-bearing bridge counter to a bearing force, usually the locally active weight of a mattress which has been positioned on top and of a person who is resting on said mattress, is more yielding than the flexibility of the main, load-bearing bridge itself.

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.

Abstract: The arrangement comprises mounting supports for the spring slats, insertable in the longitudinal beams of the bedstead, with two upper spring-slats serving as a support for the mattress and undulating spring-slats situated below them. A tiltable holding part having four receptacles for the spring-slats is fitted on a plug of the mounting support. Below the plug there is a resilient bearing pad enabling the holding part to deflect vertically. The upper spring-slats are bent convexly upward and have a broadened cross-section in the middle. By means of the undulating lower spring-slats, a progressive spring action is achieved. There is no sagging of the mattress in the region of heavier parts of the body, optimum spring action being ensured nonetheless. It is possible to divide the bedstead into zones of differing degrees of firmness by selectively providing mounting supports with only upper spring-slats or with additional lower spring-slats.
