Abrégé

The invention relates to a biasing device for a spring element that can be used in pockets of mattresses, on slats of a slatted frame, or in upholstered seat elements. The spring element comprises a top part designed as a supporting disk (3), and a bottom part designed as a base plate (4). A spring member, which cooperates with a biasing device for mounting the spring element in order to limit the excursion of the spring, is arranged between the supporting disk and the base plate. According to the invention, the biasing device (1) is arranged within the spring element (2) as an integrated element (6) for limiting the excursion of the spring.

The invention relates to a support element for a cushion cover for seating and lying areas, preferably for mattresses, comprising a baseplate that can be fixed to a base, and at least one spring element formed by a plurality of spring arms and extending upward from the baseplate (2) in the direction of the cushion cover, wherein the spring arms each are provided with a substantially U-shaped corrugated spring element on the upper ends thereof, oriented away from the baseplate, said corrugated spring element comprising at least two parallel spaced spring legs located on concentric ring tracks and disposed about the central axis of the support element and at least one connecting bar joining the spring legs, one end of the spring leg located on the inner ring track being connected to the corresponding spring arm, and one end of the spring leg located on the outer ring track being connected to the support plate provided for supporting the cushion element. According to the invention, the support plate (14) comprises a ring-shaped frame part (15) connecting the upper ends of the spring legs (11, 12) of the corrugated spring elements (7) and a support disc (16) rotatable about the central axis (8) of the support element (1) in the frame part (15), wherein the support disc (16) is provided in the outer edge region thereof with an adjusting device for limiting the movement of the spring legs (11 and 12) of the corrugated spring elements (7).

Abrégé

The invention presents a fold-away bed which is provided with a lying surface comprising a head part and a foot part, which are each formed from a U-shaped framework with a slatted base, with the free limb ends of the frameworks of the head part and of the foot part being pivotably mounted on a frame, which is arranged transverse to the lying surface, in the central region of the lying surface, and connection pieces which can be pivoted out at the ends of the head part and the foot part and permit an elevated connection position of the lying surface to the frame in the unfolded state of the head part and the foot part, with the frame being of such a size that it corresponds to the dimensions of a folded mattress support when the fold-away bed is in the folded non-use position. According to the invention, in the case of this fold-away bed, the connection pieces (9) and (10) of the foot part (2) and the head part (3) are connected to the frame (8) by means of at least one pivot joint assembly in each case, with the pivot joint assembly being operatively connected to the frame (8) in such a way that the connection pieces (9) and (10) are automatically pivoted into the connection position during the unfolding process and are pivoted back into the non-use position during the folding-up process.
