Definitions
- TITLE PANEL FOR A FURNITURE ELEMENT EQUIPPED WITH A SUPPORT STRUCTURE
- the present invention relates to a panel, in particular a noise attenuating panel, for a piece of furniture provided with a support structure.
- the invention finds a particularly advantageous, but not exclusive, application in the aeronautical field, in particular for "business class” and "first class” type seat units in an aircraft cabin.
- Such a seat unit comprises a seat and a shell extending at least partly around the seat so as to delimit a semi-enclosed space around the passenger.
- noise attenuating panels comprising padding may be secured to the seat unit.
- the flexible padding may be secured to a solid support configured to limit contact between the padding and a seat structure by creating an air gap to independently certify the noise attenuating panels and the seat unit for compliance with fire regulations.
- the invention aims in particular to effectively remedy this drawback by proposing a panel for a piece of furniture comprising at least: - a filling,
- - fixing means capable of fixing the panel to one face of the furniture item.
- the invention thus makes it possible, thanks to the support structure, to reduce the mass of the panel and therefore of the furniture elements, such as the aircraft seat units. This contributes to reducing fuel consumption, leading to a reduction in harmful emissions (CO, CO2, NOx, etc.).
- the invention also makes it easier to pass certification tests, in particular fire resistance tests, since the panel can be certified independently of the piece of furniture on which the panel is installed.
- the support structure comprises a plurality of elongated structural elements arranged so as to extend at least along a periphery of the panel.
- the support structure comprises a structural layer arranged so as to extend at least along a periphery of the panel.
- the fixing means are arranged on the support structure.
- the fastening means are removable fastening means, in particular textile fasteners formed by complementary loops and hooks, snap devices, press studs and/or magnetic fasteners.
- the support structure is arranged inside a groove made in the packing.
- the support structure is fixed directly to one face of the lining so that the support structure projects relative to said face of the lining made of flexible material.
- the filling made of flexible material is made of a material chosen from a foam, a fibrous material, a non-woven material, felt, a wadding-based material and/or a mixture of such materials.
- the invention also relates to an assembly comprising a piece of furniture and a panel as previously defined which is fixed to one face of the piece of furniture.
