CA 2238849

Apparatus for adjusting the spatial relationship between the bottom and the back of a chair which may be subjected to severe mechanical stress, as in the case of a vehicle crash, the seat and the back being operatively connected respectively to two oppositely threaded portions of a rotatable shaft which is adapted to be rotated in one direction or the other to produce the desired change in spatial relationship, the arrangement providing the combination of exceptional strength in the event of a crash and reduced cost. The operative connection between the chair parts and the shaft includes two non-rotatable parts engaged respectively with the oppositely threaded shaft portions SG as to move in and out with respect to the shaft as the latter is rotated, and a housing which permits those parts to thus move while preventing their rotation.

Appareil pour régler la relation spatiale entre le dessous et le dos d'un siège-baquet qui peut être soumis à une forte contrainte mécanique, comme un accident de voiture. Le siège et le dos du siège-baquet sont raccordés respectivement à deux parties filetées opposées d'un arbre rotatif adapté à tourner dans un sens ou dans l'autre de façon à produire le changement désiré de relation spatiale. L'ensemble qui présente une force exceptionnelle en cas d'accident coûte peu cher. La connexion entre les parties du siège-baquet et l'arbre comprend deux parties non rotatives accouplées respectivement aux parties d'arbre filetées opposées de façon à coulisser par rapport à l'arbre lors de la rotation de ce dernier. La connexion comprend également un logement qui permet aux parties non rotatives de se déplacer tout en les empêchant de tourner.
