The invention relates to a force supporting module (10) for providing a load- dependent supporting force, especially for a lowerable over-head luggage compartment in an aeroplane. Said module comprises a housing (18), a spring system for producing the supporting force, whereby one end thereof can be rotatably coupled in the housing (18) about an axis (Z) and the opposite other end thereof fixes a point of application of force (P). Said module also comprises a force supporting device which is secured on or close to the point of application of force (P) for transmitting a supporting force to a location which is remote from the force supporting module, a support (36) which is rotationably mounted in the housing (18) and on which a track (40) is provided, along which the point of application of force (P) can be displaced back and forth between a first end point (A) and a second end point (B). Said module further comprises an adjusting device (52) which interacts with the support (36) and the load sensor, and which turns the support (36), according to the load detected by sensor in order to modify the angle between the direction of application of force of the supporting force at the point of application of force (P) and the force supporting device such that it is possible to adapt the amount of the supporting force acting upon the force transmitting device to the determined load.

L'invention concerne un module de servo-assistance (10) destiné à fournir une force d'assistance en fonction d'une charge, en particulier pour un compartiment à bagages abaissable installé au plafond d'un avion. Ce module de servo-assistance comprend un boîtier (18) et un système à ressort conçu pour produire cette force d'assistance, une extrémité de ce système étant articulée dans ce boîtier (18) de façon à pouvoir pivoter autour d'un axe (Z) et son extrémité opposée déterminant un point d'application d'une force (P). Ce module comporte également un dispositif de transmission de force, fixé au niveau ou à proximité de ce point d'application d'une force (P) et conçu pour transmettre une force d'assistance à un lieu éloigné du module de servo-assistance, ainsi qu'un appui (36) monté rotatif dans le boîtier (18) et sur lequel se trouve une glissière (40) le long de laquelle le point d'application d'une force (P) peut effectuer un mouvement de va-et-vient entre un premier point d'extrémité (A) et un second point d'extrémité (B). Ce module comprend enfin un dispositif d'ajustage (52) coopérant avec cet appui (36) et un capteur de charge, lequel dispositif déforme ledit appui (36) en fonction de la charge déterminée par ce capteur, afin de faire varier l'angle entre le sens d'application de ladite force d'assistance, au point d'application d'une force (P), et le dispositif de transmission de force et d'adapter ainsi la grandeur de la force d'assistance exercée sur le dispositif de transmission de force.
