  • Patent number: 11172766
    Abstract: A support apparatus for supporting padding of seating and/or lounging furniture that has a base body with spring elements for flat support of the padding and a loading/relief apparatus for achieving pressure loading or relief on the padding. The loading/relief apparatus acts on a spring element to achieve pressure loading or relief. The loading/relief apparatus has an electric motor in operative connection with at least one pressure element by which a pressure force is exerted or exertable on a spring element to achieve pressure loading or relief. The loading/relief apparatus has a first carriage in drive connection with an electric motor and is translationally movable in the longitudinal direction of the support apparatus. The first carriage bears at least one arm whose free end carries the pressure element for load/relief of the spring elements.

  • Patent number: 10477977
    Abstract: Electric motor driven adjustable mattress has a shared casing accommodating a flat cushion element of a cushion structure and an electric motor driven adjustable support apparatus for supporting cushion element. Support apparatus has two support parts adjustable relative to one another, and on their sides facing cushion element are provided with spring elements elastically resiliently supporting cushion element. For adjusting the support parts, an electric motor driven drive apparatus is in shared casing. In each case two support parts of support apparatus adjustable relative to one another are connected via a pivot axis. Support apparatus has two bending and folding axes spaced apart from along longitudinal direction of support apparatus and situated so that for folding mattress, support parts together with cushion element on it may be folded together; in folded state extension of the mattress in its longitudinal direction is smaller than in the unfolded state.

  • Patent number: 10010464
    Abstract: An adjustable support device adjustable by an electric motor, for supporting padding of seating or reclining furniture has an outer frame and a base body having at least two support parts. The two support parts are adjustable relative to one another. An adjustment element, which is in drive connection with a drive unit, is associated with at least one of the adjustable support parts. The adjustment element is a pivot lever which is pivotable under the traction effect of a pull cable of a Bowden cable, and the pivot lever is pivotably connected to the associated support part, and is supported on a support situated on the outer frame. Or the pivot lever is pivotably connected to the outer frame, and with its free end forms a support for the support part to be adjusted.

  • Patent number: 9877589
    Abstract: Electromotively adjustable support apparatus for supporting padding of seating and/or reclining furniture, in particular a mattress of a bed, has at least two support parts adjustable relative to one another. The adjustable support apparatus may be adjusted by an electric motor. An adjustment element is associated with one support part for adjusting the support part. Adjustment element is in drive connection with an electric motor of a drive unit. The adjustment element is a pivot lever which is pivotable under the traction effect of a pull cable of a Bowden cable, and is configured and connected with the pull cable in such a way that the lever arm which is operative for adjusting the support part lengthens during an adjustment from an unadjusted starting position into a maximally adjusted end position of the adjustment movement.
