Abstract

The seat (1) has a backrest (3) including a locking mechanism for locking the backrest in a use position and a folded back position. The locking mechanism is arranged to be activated by setting the backrest in one of the two positions. The mechanism is connected to an actionable control unit by a user so as to deactivate the mechanism in order to carry out rotation of the backrest. The mechanism remains deactivated when the backrest is in the course of being folding back. A detection device (5) detects the deactivation of the mechanism.

Description

L'invention concerne un siège de véhicule automobile. Il est connu de réaliser un siège de véhicule automobile comprenant une assise et un dossier actionnable en rotation autour d'un axe entre une position d'utilisation et une position rabattue contre ladite assise, ledit dossier comprenant en outre un dispositif de verrouillage dudit dossier en position d'utilisation et en position rabattue, ledit dispositif de verrouillage étant agencé pour : - être activé par mise dudit dossier dans l'une et l'autre desdites positions, ledit dispositif de verrouillage étant connecté à au moins un organe de commande actionnable par l'utilisateur pour le désactiver afin de réaliser la rotation dudit dossier, - rester désactivé lorsque ledit dossier est en cours de rabattement. The invention relates to a motor vehicle seat. It is known to make a motor vehicle seat comprising a seat and a backrest operable in rotation about an axis between a position of use and a position folded against said seat, said folder further comprising a locking device of said backrest. position of use and in folded position, said locking device being arranged to: - be activated by placing said folder in one and the other of said positions, said locking device being connected to at least one control member operable by the user to deactivate it in order to rotate said folder, - remain deactivated when said folder is being folded.

L'organe de commande peut notamment être actionné de façon non intentionnelle, ou par un enfant, alors qu'un siège pour enfant est fixé sur le siège de véhicule, ceci étant susceptible de se produire d'autant plus que ledit organe est éloigné dudit siège de véhicule, par exemple en étant disposé dans le coffre du véhicule. The control member may in particular be unintentionally actuated, or by a child, while a child seat is fixed on the vehicle seat, this being likely to occur especially since said member is removed from said vehicle seat, for example by being disposed in the trunk of the vehicle.

La présence d'un tel siège pour enfant risque donc de conduire à une situation de rabattement partiel du dossier, ledit rabattement étant arrêté par ledit siège pour enfant, où ledit dossier est déverrouillé, ce qui peut présenter un risque pour l'enfant installé dans ledit siège pour enfant. The presence of such a child seat may therefore lead to a situation of partial folding of the folder, said folding being stopped by said child seat, where said folder is unlocked, which may present a risk for the child installed in said child seat.

En outre, lorsque le siège de véhicule est monté sur des glissières de réglage de son positionnement longitudinal, et que le rabattement du dossier entraine un déverrouillage desdites glissières, il peut se produire une propulsion dudit siège vers l'avant en cas de collision ou de freinage brutal du véhicule, ce qui est dangereux pour les occupants. L'invention a pour but de pallier ces inconvénients. In addition, when the vehicle seat is mounted on the longitudinal adjustment of its adjustment slideways, and the folding of the backrest causes an unlocking of said rails, it can occur propelling said seat forward in case of collision or brutal braking of the vehicle, which is dangerous for the occupants. The invention aims to overcome these disadvantages.

A cet effet, l'invention propose un siège de véhicule automobile comprenant une assise et un dossier actionnable en rotation autour d'un axe entre une position d'utilisation et une position rabattue contre ladite assise, ledit dossier comprenant en outre un dispositif de verrouillage dudit dossier en position d'utilisation et en position rabattue, ledit dispositif de verrouillage étant agencé pour : - être activé par mise dudit dossier dans l'une et l'autre desdites positions, ledit dispositif de verrouillage étant connecté à au moins un organe de commande actionnable par l'utilisateur pour le désactiver afin de réaliser la rotation dudit dossier, - rester désactivé lorsque ledit dossier est en cours de rabattement, ledit siège comprenant en outre un dispositif de détection de la désactivation dudit moyen de verrouillage. For this purpose, the invention provides a motor vehicle seat comprising a seat and a backrest operable in rotation about an axis between a position of use and a position folded against said seat, said folder further comprising a locking device said folder in the use position and in the folded position, said locking device being arranged to: - be activated by placing said folder in one and the other of said positions, said locking device being connected to at least one member of control operable by the user to disable it to perform the rotation of said folder, - remain disabled when said folder is being folded, said seat further comprising a device for detecting the deactivation of said locking means.

De la sorte, le conducteur du véhicule peut être informé de la présence d'un dossier non verrouillé alors que peut se trouver sur le siège de véhicule correspondant un siège pour enfant. D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence aux figures jointes, dans lesquelles : - la figure 1 est une vue latérale partielle d'un siège selon une réalisation, le dossier dudit siège étant en position d'utilisation, - la figure 2 est analogue à la figure 1, le dossier étant en position rabattue.
