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.

Claims16

Dependent claims

A support apparatus for supporting a padding of seating and/or lounging furniture, the support apparatus comprising:

a) a base body with a plurality of spring elements for flat support of the padding;
b) at least one loading/relief apparatus for achieving pressure loading or relief on the padding, and the loading/relief apparatus acts on at least one of the plurality of spring elements to achieve pressure loading or relief;
c) the loading/relief apparatus has a plurality of electric-motor driven linear drives in operative connection with a plurality of pressure elements, by which a pressure force is exerted or excitable on at least one spring element of the plurality of spring elements to achieve pressure loading or relief;
d) the loading/relief apparatus has a first carriage that is in drive connection with a first electric-motor driven linear drive and is translationally movable in a longitudinal direction of the support apparatus, and the first carriage bears at least one arm whose free end carries the plurality of pressure elements for loading/relief of the plurality of spring elements;
e) the plurality of spring elements are elastic slats that are connected to one another via at least one flexible band, and one of the plurality of pressure elements rests against the flexible band for loading/relief of the elastic slats via the flexible band;
f) the plurality of pressure elements are adjustable relative to the plurality of spring elements in a direction toward a support plane and in a direction away from the support plane, and an adjustment drive configured as a second electric motor-driven linear drive is associated with at least one of the plurality of pressure elements;
g) the at least one of the plurality of pressure elements is situated on the free end of the at least one arm, and the adjustment drive acts as a pivot drive and is associated with the arm in order to adjust the at least one of the plurality of pressure elements relative to the plurality of spring elements;
and
h) the loading/relief apparatus together with the support apparatus and the padding are accommodated in a shared casing.
