Definitions

  • the present invention relates to the general field of furniture.
  • It relates more particularly to a suspension device for slatted bed base or seat.
  • Some seats or bed bases consist of a generally frame-shaped frame formed of an assembly of two side rails and two end rails, two of which, parallel (usually the end rails) serve supporting juxtaposed suspension devices, each comprising one or more slats.
  • These slats made of wood, plastic, resin or other, consist of elongated flat members, slightly curved, having a top face, a bottom face and two lateral ends.
  • lateral supports generally receiving endpieces provided with complementary shaped housings, fixed on the support rails of the frame.
  • the top face of the different juxtaposed slats defines a support plane, generally horizontal, for receiving a seat or sleeping structure such as a cushion or a mattress.
  • the slats support trays, possibly mounted on springs, these trays ensuring the reception of the aforementioned foundation or sleeping structure.
  • slats have a certain intrinsic flexibility, along a vertical axis, to make sitting or sleeping comfortable.
  • Their lateral supports can be in the form of ball joints adapted to optimize the suspension.
  • suspension structures for example as presented in the documents FR-2,666,973 or JP-S62 52462 , have slats on several levels separated from each other and associated with movable spacers to allow flexibility adjustment.
  • the present invention aims to overcome these disadvantages by providing a suspension device which has a concentrated deformation under the load, having more flexibility in anchoring the slats, and while maintaining a small thickness.
