Abstract: The invention relates to a bearing frame for a panel, of the type comprising a peripheral structure (1, 1?) for receiving a panel (20), including at least three mounts (2, 3, 4, 5, 2?, 3?, 4?, 5?) defining a frame in which the lower face defines a reference plane (P, P?), in which at least one mount (2, 5; 5) includes a wing (90,100; 90?) extending on the entire length thereof towards the outside of the frame in parallel with the upper face of the frame, the frame comprising at least one precut metal strip (30) stamped, folded and assembled by welding, in particular laser welding, characterised in that the peripheral structure (1, 1?) is hollow and in that it further comprises inner and outer connection means (14, 16, 17) and an electric linking means (18) between the inner and outer connection means, provided inside the hollow peripheral structure.

Abstract: Supporting frame for an electrically active panel comprising a peripheral structure for receiving an electrically active panel, the peripheral structure including an internal electrical connector for connection to an electrically active panel carried by the frame, at least one first external electrical connector for connection to a first means external to the frame, and an electrical link for electrically linking at least the internal electrical connector to at least the first external electrical connector, the electrical linking link extending along the peripheral structure so as to be concealed by the peripheral structure, the peripheral structure comprising a hollow portion in which the electrical link is received. The peripheral structure is a framework consisting of tubular uprights, the internal electrical connector and external electrical connector extending through a wall of the uprights on which they are disposed and the electrical link extending inside the tubular uprights.
