A car child seat fixing structure with a force limiting protection device

Abstract

The invention relates to an automotive child seat fixing structure with a force limitation protection device. The automotive child seat fixing structure is characterized by comprising a hook (11), a hook cover plate (12), a force limitation brace (13) and a force limitation brace stationary shaft (14), wherein the hook (11) passes through the hook cover plate (12) which is fixedly connected with a rear floor sheet metal part (2) of an automobile body; the hook (11) can slide relative to the hook cover plate (12); the hook (11) is longer than the hook cover plate (12); the force limitation brace (13) is of a U-shaped structure; one side wall of the U-shaped structure of the force limitation brace (13) is fixedly connected with one end of the hook (11); the other side wall of the U-shaped structure of the force limitation brace (13) is free; the force limitation brace stationary shaft (14) fixedly connected with the rear floor sheet metal part (2) of the automobile body passes through the bottom of the U-shaped structure of the force limitation brace (13); the other end of the hook (11) is connected with a child seat socket. The automotive child seat fixing structure has the advantages of simple structure, convenience in processing, low cost and convenience in sheet metal part connection of the automobile body.

Description

technical field [0001] The invention belongs to the technical field of car body structure design for safety protection, and in particular relates to a car child seat fixing structure with a force limiting protection device.
