Description

Technical Field

[0001] This utility model mainly relates to the field of seat belt technology, specifically to an active ventilation seat belt webbing external attachment structure. Background Technology

[0002] Traditional seat belts, especially those with wide shoulder straps, tightly cover the passenger's chest and abdomen, hindering airflow. In hot weather or after exposure to sunlight, this can easily cause the contact area to feel stuffy, sweaty, and sticky, resulting in discomfort. Designing a ventilation function in the seat belt continuously introduces airflow to remove heat and moisture from the skin's surface, keeping the contact area dry and cool.

[0003] The inventors have proposed an active ventilation seat belt webbing external attachment structure, which provides an air duct that can be externally attached to the seat belt in the vehicle's cockpit. In conjunction with a fan, it provides ventilation for the user's chest or abdomen. The air duct, fan, and seat belt can all be detached and attached for user convenience. Utility Model Content

[0005] 2. Technical Solution: To achieve the above objectives, the technical solution provided by this utility model is as follows: an active ventilation type safety belt webbing external attachment structure, including a central armrest box, and a centrifugal fan arranged close to the rear of the central armrest box. The output end of the centrifugal fan is connected to an air supply pipe, and the air outlet end of the air supply pipe is fixed with a dispersion pipe. A connecting layer is provided on the outside of the dispersion pipe, and the outside of the connecting layer is detachably connected to the outside of the safety webbing.

[0006] Furthermore, a silicone connector is fixed at the air inlet of the air supply pipe, and the silicone connector is filled at the connection between the centrifugal fan and the air supply pipe. Multiple air outlets are equally spaced at the air outlet end of the air supply pipe.

[0007] Furthermore, a plurality of skeleton plates are fixed at equal intervals in the middle of the dispersion tube, and the skeleton plates divide the middle of the dispersion tube into a plurality of exhaust zones, which are matched with the air outlet.

[0008] Furthermore, the outer side of the dispersion tube is provided with air inlets symmetrical about its middle part, which are connected to the air outlet, and the air inlets of the dispersion tube extend to the surface of the safety webbing.

[0009] Furthermore, the connecting layer can be made of snaps, Velcro, or magnetic adhesive.

[0010] Furthermore, a retractor and a lower limit clip are fixedly provided at both ends of the safety webbing, an upper limit clip is movably connected to the top of the safety webbing, a safety pin is movably connected to the middle of the safety webbing, and a safety buckle is engaged at the bottom of the safety pin.

[0011] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: This utility model provides an active ventilation seat belt webbing external structure. The silicone joint fills the gap at the connection between the air supply pipe and the centrifugal fan, and also allows for the plugging and unplugging of the air supply pipe at the air outlet of the centrifugal fan. The skeleton plate is designed inside the dispersion pipe to prevent the dispersion pipe from being completely flattened and unable to exhaust smoothly. The dispersion pipe and the air supply pipe work together to provide ventilation for the user's chest or abdominal area. The external hanging design of the dispersion pipe and the air supply pipe outside the safety webbing also facilitates user modification and disassembly after product damage. The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description
