Abstract
Abstract A mattress support in the form of a slatted frame for a bed, having individually mounted support slats which are arranged transversely relative to the lying surface and together form the resting surface for a mattress, for example. To improve its adaptability under loading, the mattress support includes the following features: a) the lifting element (6) of each support slat (1) is a self-supporting and upright bellows, the air-receiving space of which is constructed to be rigid in its cross-sectional contour and to be variable only in respect of its height and, in its effective length relative to the support slat (1), to be proportional to the associated load; b) the kinematic coupling (10, 11, 15, 16) consists of a pneumatic coupling which connects all the lifting elements (6) to one another and comprises an air distributor (15, 16) provided with an integrated damping (17, 18, 19), to which air distributor all the bellows are connected via in air connection (11) in each case; c) each support slat (1) rests directly on its associated bellows via a support slat bearer (5), which bellows is of slightly narrower construction than the support slat bearer (5); d) each support slat bearer (5) is guided in a forced parallel guide (7, 8, 9) which ensures its parallel displacement relative to itself.
