[0002] Traditional seat belt covers are fixed by sponge structures. After being squeezed by the cover for a long time, the sponge will collapse and interfere with the safety belt, causing the seat belt to rebound slowly or not at all. Summary of the Invention

[0003] The utility model aims to provide a safety belt connecting structure on a seat which has a simple structure, good resilience, and is easy to install and use.

[0004] The purpose of this utility model is to solve:

[0005] A three-point safety belt connection structure for a seat includes a mounting frame that can be fixed to the upper left corner or upper right corner of a seat back, a connector and a lifting ring fixed to the mounting frame, a safety belt cover mounting plate clipped to the connector, and a safety belt cover mounted on the safety belt cover mounting plate. A through hole or a through groove through which a safety belt can pass is provided in the middle of the mounting frame, the connector, the lifting ring, the safety belt cover mounting plate, and the safety belt cover.

[0006] As a further optimization of the above technical solution, the mounting frame is a triangular structure, the middle of the triangular structure is provided with an inverted trapezoidal hole through which the safety belt can pass, and a hanging threaded hole is provided on the upper wall of the inverted trapezoidal hole.

[0007] As a further optimization of the above technical solution, the hanging hole on the upper part of the hanging ring is screwed onto the hanging threaded hole by a bolt, and the lower part of the hanging ring is provided with a horizontal strip hole for the safety belt to pass through, and the two ends of the strip hole extend upward and inward to form a semicircular hole that passes through the strip hole, and a row of grooves are provided at horizontal intervals on the back of the lower wall of the strip hole.

[0008] As a further optimization of the above technical solution, the connecting member is a U-shaped rod, and the middle part of the U-shaped rod forms a through groove through which the safety belt can pass. The middle parts of the two side arms of the U-shaped rod are bent forward to form a clamping position for clamping the safety belt cover mounting plate, and the clamping hooks arranged on both sides of the safety belt cover mounting plate are clamped on the clamping positions.

[0009] As a further optimization of the above technical solution, the connecting member is formed by bending a steel rod.

[0010] As a further optimization of the above technical solution, a downwardly curved arc groove is provided in the middle of the seat belt outer cover, and the arc groove smoothly transitions to the front and rear end surfaces of the seat belt outer cover.

[0011] As a further optimization of the above technical solution, a downward curved arc groove is provided in the middle of the safety belt cover, the rear wall of the arc groove is first turned backward and then turned outward, and the corners of the rear and outward turns are smoothly transitioned.

[0012] As a further optimization of the above technical solution, a downwardly curved arc-shaped groove is provided in the middle of the safety belt outer cover, and an opening is provided in the middle of the lower wall of the arc-shaped groove.

[0013] As a further optimization of the above technical solution, more than three threaded grooves are provided around the rear part of the seat belt cover, a through hole for passing the seat belt is provided in the middle of the seat belt cover mounting plate, and more than three through holes are provided on the seat belt cover mounting plate outside the through hole. The seat belt cover is mounted on the seat belt cover mounting plate by screws passing through the through holes and screwed onto the threaded grooves.

[0014] As a further optimization of the above technical solution, one end of the webbing is provided with a buckle through the through hole or the through slot, and the other end is provided with a retractor. The seat belt connection structure is installed on the frame at the upper left corner or the upper right corner of the seat, and the retractor is installed on the back frame of the seat back.

[0015] The outstanding advantages of the utility model compared with the prior art are:

[0016] 1. The safety belt cover of the utility model is connected to the connecting piece through the hook of the safety belt cover mounting plate, which is convenient for quick disassembly and assembly and easy operation.

[0017] 2. The lifting ring of the present invention is screwed onto the threaded suspension hole by means of bolts, so that the force direction of the safety belt and the lifting ring can be adjusted in time when external forces in different directions act on the safety belt.

[0018] 3. The semicircular hole that passes through the strip hole in the lifting ring of the present invention is designed so that when the safety belt is pulled tilted, one side of the safety belt can enter the semicircular hole, thereby guiding the safety belt and preventing the safety belt from curling locally at that location.

[0019] 4. The middle parts of the two side arms of the U-shaped rod of the utility model are bent forward to form a snap-in position for the seat belt cover mounting plate, which reserves space for installing the seat belt cover mounting plate and the lifting ring. The structure is simple, saves raw materials, and provides space for the seat belt cover mounting plate and the seat belt cover to move elastically.

[0020] 5. The utility model has a simple structure, good resilience, and is easy to install and use. It is suitable for installing and using the safety belt on the upper left corner or the upper right corner of the seat back. BRIEF DESCRIPTION OF THE DRAWINGS
