Problems solved by technology
[0003] When the safety belt is pulled out or retracted, the noise is relatively large, which affects the comfort of the passengers. Therefore, the general car safety belt is equipped with a safety belt noise box, which can reduce the noise. There is a lot of noise when retracting the safety belt, and it is not smooth after a long time. Moreover, due to the limitation of its material, there will be a large smell when using it, which leads to the smell detection exceeding the standard, which is not environmentally friendly.

The invention discloses a car safety belt noise box and a production method thereof and relates to the technical field of car spare parts. Specifically, the car safety belt noise box comprises a box body, a safety belt bayonet and a connecting bayonet. The safety belt bayonet is formed in the front face of the box body. The connecting bayonet is arranged under the box body. According to the car safety belt noise box and the production method thereof, the car safety belt noise box can be installed at the corresponding position, noise made by pulling out or drawing back of a safety belt is reduced, the comfort level of users is improved, the product performance is improved substantially compared with a common safety belt noise box, the appearance is beautiful, the sound isolating performanceis perfect, all indexes of products meet the requirement of car detection, and especially the smell requirement which all cars pay attention to, and compared with the common safety belt noise box with materials being not environmentally friendly and smell not reaching the standard, the car safety belt noise box can pass through the smell detection items and is safer and more environmentally friendly.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to an auto insurance belt noise box and a production method thereof. Background technique [0002] Car seat belts, also known as car safety belts, are the basic protective devices for protecting drivers and passengers during a car collision. A safety device that rushes out of the car to cause death or injury during the first collision or avoids a collision. Car seat belts are generally recognized as the cheapest and most effective safety device. In vehicle equipment, seat belts are mandatory in many countries. [0003] The noise of the seat belt is relatively loud when it is pulled out or retracted, which affects the comfort of the passengers. Therefore, the general car seat belt is equipped with a seat belt noise box to reduce the noise. However, the currently used seat belt noise box is When retracting the safety belt, the noise is loud, and it is not smooth after a long time....
