CA 2504464

A seat assembly having a tunable tie bar is provided and includes a main pivot and a housing operably supporting the tie bar. The housing is fixedly attached to a seatback of the seat assembly and includes C-shaped members fixedly joined together to provide a space in which the tie bar is disposed. The tie bar is fixedly attached to the housing and is in engagement with the main pivot, whereby the tie bar reacts against the main pivot to provide the seatback with sufficient support. The tie bar serves to strengthen the housing and ultimately provide the seatback with sufficient strength to support an occupant and the accompanying seatbelt loads associated with a seat-mounted retractor assembly. The tie bar is tunable between different seating applications and as such, allows the housing to be used in various seating applications and does not require extensive design and tooling for each application.

La présente invention concerne un ensemble de siège possédant une armature de liaison réglable, qui inclut un pivot principal et une enveloppe supportant de manière opérationnelle cette armature de liaison. Cette enveloppe est attachée de manière fixe au dossier de l'ensemble siège et comprend des éléments en forme de C reliés ensemble de manière fixe de façon à offrir un espace dans lequel l'armature de liaison est placée. Cette armature de liaison est attachée de manière fixe à l'enveloppe et est en contact avec le pivot principal, cette armature de liaison réagissant contre le pivot principal de façon que ce dossier puisse offrir un support suffisant. Cette armature de liaison sert à renforcer l'enveloppe et finalement à offrir une résistance suffisante de ce dossier pour supporter un occupant et les charges de ceinture de sécurité associées à un ensemble enrouleur automatique monté sur le siège qui l'accompagne. Cette armature de liaison est réglable entre différentes applications d'assise et de ce fait, elle permet d'utiliser l'enveloppe dans différentes applications d'assise et ne nécessite pas de conception étendue ni d'outillage pour chaque application.
