The safety belt guide ring is installed on the guide ring mounting plate, and the guide ring mounting plate is assembled on the side wall sheet metal of the vehicle body. The lower fixed end piece of the safety belt is installed on the lower fixed end piece support, and the lower fixed end piece support is assembled on the front floor sheet metal of the vehicle body. the

The upper part of the retractor bracket is fixedly connected with the retractor connector, the top edge is provided with positioning claws, and the lower part is provided with at least two assembly holes, and the corresponding assembly holes are provided on the sheet metal of the rear support beam of the body side wall, which are fixed by rivets. Connect the retractor bracket with the body side wall rear support beam sheet metal. the

The middle part of the guide ring mounting plate is fixedly connected with a guide ring connector, and there are at least two assembly holes on both sides. Corresponding assembly holes are provided on the side panel of the body. Around the sheet metal connection. the

The lower fixed end piece support includes a first side wall and a second side wall perpendicular to each other; the middle part of the first side wall is fixedly connected with a lower fixed end piece connector; the second side wall is provided with at least two assembly holes, and the front floor of the vehicle body Corresponding assembly holes are provided on the sheet metal, and the lower fixed end piece bracket is connected to the front floor sheet metal of the vehicle body through fasteners such as fastening rivets. the

The connecting part of the retractor, the connecting part of the guide ring and the connecting part of the lower fixed end piece are all nuts. the

Adopting such a structure has the following advantages: lower requirements on the strength of the body material itself, adapt to the configuration of various body materials, especially including aluminum body; it can be replaced for easy maintenance; the strength of the fixed point can be strengthened. the
