Description

Technical Field

[0001] This application relates to the field of car seat covers, and more particularly to a car seat cover that facilitates the release of an airbag. Background Technology

[0002] Currently, more and more people are using cars as a means of transportation, and traffic accidents such as crashes and rear-end collisions are becoming more and more frequent. When a car is involved in a traffic accident, the vehicle body suffers a severe impact, causing physical pain to passengers and huge economic losses. To ensure the safety of people inside the car, most existing cars are equipped with airbags in the seats, and airbags are no longer limited to the steering wheel, dashboard, and glove box.

[0003] The airbags in the seats are usually side airbags, located on either side of the driver and front passenger seats, near the B-pillar. To enhance the aesthetics and comfort of the car, people often use seat covers. However, ordinary seat covers are usually a single piece at the backrest, covering both sides and the front and back of the backrest. This effectively obscures the side airbags. In the event of an accident, because the seat cover obscures the airbag, it is difficult for the airbag to deploy and provide timely protection. Summary of the Invention

[0004] To protect the personal safety of passengers, this application provides a car seat cover that facilitates the release of airbags.

[0005] The car seat cover provided in this application, which facilitates the release of airbags, adopts the following technical solution:

[0006] A car seat cover for easy airbag release includes a body, a cover fabric, and Velcro. The body has an installation opening on the side wall near the door. One end of the cover fabric is fixedly connected to the inner wall of the installation opening facing the front of the vehicle, and the other end of the cover fabric is fixedly connected to the body via Velcro. The cover fabric is used to cover the installation opening.

[0007] By adopting the above technical solution, the main body and the cover cloth are connected by Velcro. After the airbag deploys, the Velcro on the main body and the cover cloth separates, and the cover cloth does not cover the installation opening. The airbag extends out from the installation opening. The detachable connection between the main body and the cover cloth facilitates the normal deployment of the airbag, reduces the probability of personal safety being threatened by the airbag failing to deploy, reduces the probability of the main body exploding due to the airbag deployment, facilitates repeated use of the seat cover, improves resource utilization, and the cover cloth is connected to the inner wall of the installation opening facing the front of the vehicle to prevent the cover cloth from attacking the occupant when the airbag deploys, thus protecting the personal safety of the occupant.

[0008] Preferably, the car seat cover for easy airbag release also includes a backrest airbag, which is fixedly connected to the side of the main body facing the front of the vehicle. The backrest airbag has an air chamber for filling with gas and is used for the passenger's back to rest against.

[0009] By adopting the above technical solutions, the airbag improves the comfort of passengers and plays a certain role in buffering the impact of safety accidents, thus protecting the personal safety of passengers.

[0010] Preferably, the car seat cover for easy airbag release further includes a reaction box, a rotating rod, a water tank, a stop plate, a guide tube, and an air guide tube. The reaction box is fixedly connected to the side wall of the main body facing the car door. The rotating rod and the water tank are both fixedly connected to the side of the cover fabric facing the car door. The rotating rod is located at the connection between the cover fabric and the main body. The lower end of the rotating rod extends into the reaction box. The rotating rod has a flow channel that extends downward to penetrate the rotating rod. The stop plate is fixedly connected to the inner wall of the reaction box and has a drain outlet. The stop plate is used to control the opening and closing of the flow channel. One end of the guide tube is connected to the water tank, and the other end of the guide tube is connected to the flow channel. One end of the air guide tube is connected to the reaction box, and the other end of the air guide tube is connected to the air chamber. The water tank is used to hold the first reactant, and the reaction box is used to hold the second reactant. The first and second reactants are used to mix and react to generate gas.

[0011] By adopting the above technical solution, the cover cloth and the main body are fixedly connected by Velcro. At this time, the abutment plate covers the flow channel, the water tank contains the first reactant, and the reaction box contains the second reactant. When a safety accident occurs, the airbag is deployed, the cover cloth separates from the main body, the rotating rod rotates, the drain outlet connects with the flow channel, the first reactant falls into the reaction box and mixes with the second reactant to produce gas. The gas enters the air chamber from the air guide tube, enhancing the elasticity of the airbag and better protecting the personal safety of the passenger.

[0012] Preferably, the lower end of the rotating rod is coaxially provided with a rotating groove, the lower end of the flow channel is connected to the groove wall of the rotating groove, the upper end of the abutment plate is connected to a support block, the support block is embedded in the rotating groove, the diameter of the support block is equal to the diameter of the rotating groove, the support block is provided with a notch, the notch is connected to the rotating groove and the drain outlet, and the support block is used to control the opening and closing of the flow channel and the rotating groove.

[0013] By adopting the above technical solution, the support block is embedded in the rotating groove, and the support block limits the rotation of the rotating rod, making the control of the flow channel more stable. When the seat cover is in normal use, the support block abuts against the flow channel. When a safety accident occurs, the rotating rod rotates to connect the flow channel with the notch, and the first reactant falls into the reaction box.

[0014] Preferably, the car seat cover for easy airbag release also includes an elastic sheet, the lower end of the abutment plate is provided with an installation groove, the drain outlet is connected to the bottom of the installation groove, the outer periphery of the elastic sheet is fixedly connected to the groove wall of the installation groove and is used to cover the drain outlet, the elastic sheet is provided with a connecting seam, the connecting seam passes through the center of the elastic sheet, and there are multiple connecting seams, which are evenly spaced around the axis of the elastic sheet.

[0015] By adopting the above technical solution, when the flow channel is connected to the drain outlet, the first reactant causes the elastic sheet to flip downwards, and the connection seam opens to allow the first reactant to fall into the reaction box. Since the elastic sheet is embedded in the installation groove, it cannot flip upwards, reducing the probability of the gas generated by the reaction flowing back into the water tank, making the inflation of the airbag more stable.

[0016] Preferably, the reaction box includes a box body and a cover. The box body is fixedly connected to the end of the main body facing the vehicle door. The upper end of the box body is provided with a feed inlet. The cover is detachable from the box body and covers the feed inlet.

[0017] By adopting the above technical solution, it is easy to add the second reactant into the reaction box, easy to clean the reaction box, and the operation is simple.

[0018] Preferably, the car seat cover for easy airbag release also includes an air supply airbag and an air intake pipe. The air supply airbag is located on the side of the car, one end of the air intake pipe is connected to the air supply airbag, and the other end of the air intake pipe is connected to the airbag in contact with the airbag.

[0019] By adopting the above technical solution, when a car is hit from the side, the airbag deforms, and the gas in the airbag quickly rushes into the airbag through the intake pipe to protect the occupants.

[0020] Preferably, the air supply bag is provided with an air inlet, and the inner wall of the air inlet is connected to a one-way valve. The air inlet is used to allow an external air pumping device to pump air into the air supply bag.

[0021] By adopting the above technical solution, after a safety accident occurs, air is pumped into the air supply bag to prevent the next safety accident from happening. If the air supply bag is not damaged, there is no need to replace the airbag, thus reducing resource waste.

[0022] Preferably, the car seat cover for easy airbag release also includes a valve, wherein the upper end of the cover that is in contact with the airbag is provided with an exhaust port, and the valve is connected to the inner wall of the exhaust port and is used to control the opening and closing of the exhaust port.

[0023] By adopting the above technical solution, when too much gas is filled into the airbag, the valve opens to slowly release the gas, reducing secondary injury to the passenger caused by the over-inflated airbag bursting and protecting the passenger's personal safety.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The seat cover and the cover are connected by Velcro. After the airbag deploys, the Velcro on the seat cover and the cover separates. The cover does not cover the mounting opening, and the airbag extends out from the mounting opening. The detachable connection between the seat cover and the cover facilitates the normal deployment of the airbag, reduces the probability of personal safety being threatened by the airbag failing to deploy, and reduces the probability of the seat cover exploding due to the airbag deployment. It is easy to reuse the seat cover, improving resource utilization. The cover is connected to the inner wall of the mounting opening facing the front of the vehicle to prevent the cover from attacking the occupant when the airbag deploys, thus protecting the occupant's personal safety.

[0026] 2. Secure the cover to the main body with Velcro. At this time, the abutment plate covers the flow channel. The water tank contains the first reactant, and the reaction box contains the second reactant. When a safety accident occurs, the airbag deploys, the cover separates from the main body, the rotating rod rotates, the drain outlet connects to the flow channel, the first reactant falls into the reaction box and mixes with the second reactant to produce gas. The gas enters the air chamber through the air guide tube, enhancing the elasticity of the airbag and better protecting the personal safety of the passenger.

[0027] 3. When the flow channel is connected to the drain outlet, the first reactant causes the elastic sheet to flip downwards, and the connection seam opens to allow the first reactant to fall into the reaction box. Since the elastic sheet is embedded in the installation groove, it cannot flip upwards, reducing the probability of the gas generated by the reaction flowing back into the water tank, making the inflation of the airbag more stable.
