Summary:The seat, comprising a padded base (2) with a frame formed by two side members (10), a rear cross-member (11) and a support, and a back (3) with side members (13) connected to the base by pivot mechanisms (5, 6) with a connecting bar (15), has the support (17) made to deform from the inertia of a seated passenger in the event of a rear impact. This causes the support to interact with with the eccentric middle section (15b) of the bar (15), preventing the latter from moving into the unlocked position. The support and two child seat anchoring points (20) are made from metal rod in an inverted U-shape, welded to the seat's rear crossmember (11). Siège de véhicule automobile comprenant un dossier (3) et une assise (2) pourvue d'une matelassure portée par une structure qui comprend un élément de maintien (17) coopérant avec la matelassure pour la maintenir en position. Le siège comprend une barre de liaison (15) reliant deux mécanismes d'articulation (5, 6) permettant le pivotement du dossier sur l'assise.L'élément de maintien est adapté pour être déformé par effet d'inertie d'un passager assis sur l'assise, lorsque le siège subit un choc arrière de façon que l'élément de maintien (17) coopère par accrochage avec la barre de liaison (15) pour éviter une rotation accidentelle du dossier.
