The frame of a crash resistant school bus seat is designed to undergo plastic flow when an impact is applied to the back rest portion of the seat. One or more stopping mechanisms are provided to retard movement of the back rest farther than a predetermined limit, thereby keeping a passenger in an upright position in the seat as a result of a crash. The frame is made from inexpensive, off-the-shelf metal tube and sheet stock and hence is inexpensive to design and build. Image
Selon l'invention, le cadre d'un siège, d'autobus d'école, résistant aux collisions, est conçu afin d'avoir un comportement de type écoulement plastique lors de l'application d'un impact sur le dossier du siège. Un ou plusieurs mécanismes d'arrêt permettent de retarder le mouvement du dossier au delà d'une limite prédéterminée, ce qui permet au passager, lors d'une collision, de conserver une position verticale sur le siège. Le cadre est constitué de tube métallique et de stock de feuilles disponibles, et donc peu coûteux à concevoir et à construire.
