Abstract

Siège inclinable comprenant un dispositif d’absorption d’énergie Le siège (10) comprend un dossier (14) mobile en rotation entre une position relevée et une position inclinée, et un dispositif d’absorption d’énergie (16) par déformation, comprenant un élément rigide (22) agencé pour se déplacer en déformant un élément d’absorption (20) lorsqu’une force d’impact est appliquée sur le siège (10). Un dispositif de blocage (18) du dispositif d’absorption (16) est mobile entre une position inactive, dans laquelle l’élément rigide (22) du dispositif d’absorption d’énergie (16) se déplace en déformant l’élément d’absorption (20) lorsqu’une force d’impact est appliquée sur le siège (10) alors que le dossier (14) est dans la position inclinée, et une position active, dans laquelle le dispositif de blocage (18) empêche le déplacement de l’élément rigide (22) du dispositif d’absorption d’énergie (16) lorsqu’une force d’impact est appliquée sur le siège (10) alors que le dossier (14) est dans la position relevée. Figure pour l'abrégé : Figure 1Reclining seat comprising an energy absorbing device The seat (10) comprises a backrest (14) movable in rotation between a raised position and a reclined position, and an energy absorbing device (16) by deformation, comprising a rigid member (22) arranged to move by deforming an absorption member (20) when an impact force is applied to the seat (10). A locking device (18) of the absorption device (16) is movable between an inactive position, in which the rigid element (22) of the energy absorption device (16) moves by deforming the element d. absorption (20) when an impact force is applied to the seat (10) while the backrest (14) is in the reclined position, and an active position, in which the locking device (18) prevents displacement of the rigid member (22) of the energy absorbing device (16) when an impact force is applied to the seat (10) while the backrest (14) is in the raised position.
