Abstract

The invention discloses a round hole flanging safety belt end piece. The round hole flanging safety belt end piece comprises an end piece body, wherein the end piece body is provided with a free end connected with a safety belt woven belt and a fixed end connected with a car body through a fastening bolt, a round hole is formed in the free end, the safety belt woven belt penetrates the round hole and is tied tightly, and the round hole is provided with a flanging structure. In a stress state, the flanging structure is small in deformation, the damage to the woven belt is small as well, the function of preventing the woven belt from damage is achieved, and further the function of protecting passengers is achieved.

Description

technical field [0001] The invention relates to a vehicle safety protection device, in particular to an intermediate piece for connecting a safety belt webbing with a vehicle body through bolts. Background technique [0002] The seat belt end piece is an intermediate piece between the seat belt webbing and the car body, which is used to protect the webbing from being cut and damaged when it is stressed, so as to achieve the purpose of protecting the safety of the occupants. The traditional seat belt end piece is provided with a smooth plastic liner on the edge of the mounting hole of the end piece body (that is, the contact part between the end piece body and the seat belt webbing), and the plastic liner is connected with the seat belt webbing to protect the seat belt webbing. effect. However, the cost of the plastic liner is high, and the substrate installation process is added in the production. After installation, it is easy to fall off after long-term use, and the p...
