Description

Technical Field

[0001] This utility model belongs to the technical field of seat accessories, and relates to a car seat backrest. Background Technology

[0002] As people's demands for ride comfort and safety continue to increase, automakers have continuously improved the design and function of seat systems. For example, Chinese patent literature discloses an automobile seat (authorization announcement number CN210027133U), in which a fixed frame is set inside the backrest, two fixed plates are fixed to the front end of the fixed frame, and a mounting plate is fixed to the back. Massage airbags are mounted on the fixed plate and are evenly spaced side by side along the longitudinal direction of the backrest. A first solenoid valve and a first air pump are both mounted on the mounting plate. The massage airbags are connected to the exhaust port of the first solenoid valve through independent air inlet and outlet pipes. The air inlet of the first solenoid valve is connected to the first air pump through independent air inlet and outlet pipes. The ventilation system includes a first ventilation air bag, a first axial flow fan, a second ventilation air bag, and a second axial flow fan. The first ventilation air bag is installed at the bottom of the seat cushion and the first axial flow fan is located below the first ventilation air bag. The second ventilation air bag is installed inside the backrest and the second axial flow fan is located behind the second ventilation air bag.

[0003] The car seat has the following shortcomings during use: the massage airbag, the first solenoid valve, the first air pump, the first ventilation air bag, the first axial flow fan, the second ventilation air bag, and the second axial flow fan all need to be installed in different positions on the seat back, resulting in a messy structure, taking up a lot of space, and being troublesome to assemble. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a new type of car seat backrest. The technical problem this invention aims to solve is how to improve the structural compactness and ease of assembly of the massage and ventilation components within the seat backrest.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A car seat backrest includes a backrest foam, characterized in that a plurality of backrest air bags are embedded in the front side of the backrest foam, a ventilation bag and an air pump are embedded in the rear side of the backrest foam, a fan and an airflow distributor are respectively installed on the rear side of the ventilation bag, a plurality of ventilation holes are opened on the backrest foam in front of the ventilation bags, the surface of the ventilation bags has a plurality of ventilation holes respectively arranged opposite to the fan and ventilation holes, the ventilation bags are covered with a sponge cover, the fan and the airflow distributor are staggered vertically and both protrude from the sponge cover, the air inlets of the air pump and the airflow distributor are arranged adjacently and connected, and each backrest air bag is connected to the air outlet of the airflow distributor through an air pipe.

[0007] This car seat backrest incorporates several backrest airbags embedded in the front of the backrest bubble, and ventilation bags and air pumps embedded adjacently in the rear of the backrest bubble. At the same time, the fan and airflow distributor are staggered vertically on the ventilation bags, allowing the massage and ventilation components to be stacked and installed in an orderly manner. This improves the structural compactness and ease of assembly of the massage and ventilation components inside the seat backrest.

[0008] In addition, when in use, the backrest bubble is covered with a cover, and the foam cover on the ventilation bag provides cushioning protection.

[0009] In the aforementioned type of car seat backrest, the backrest foam is embedded with several foamed steel wires, and the edge of the ventilation bag has several mounting lugs. The mounting lugs are fixed to the foamed steel wires by C-shaped nails. The foamed steel wires are pre-placed in the mold during the backrest foaming process and integrally formed with the backrest foam. During installation, the C-shaped nails are passed sequentially through the mounting lugs and the backrest foam, so that the C-shaped nails simultaneously surround the mounting lugs and the foamed steel wires. Then, the two ends of the C-shaped nails are pressed together to form a closed ring, thereby fixing the mounting lugs of the ventilation bag to the foamed steel wires within the backrest foam, improving the stability of the ventilation bag installation.

[0010] In the aforementioned car seat backrest, a first mounting plate is provided on one side of the ventilation bag. The fan is mounted on the other side of the ventilation bag via several rubber rivets that pass sequentially through the first mounting plate and the ventilation bag. A fan cover is also provided on the fan. This design facilitates assembly, improves the stability of the fan after installation, and the rubber rivets also solve the problem of abnormal noise caused by vibration transmission when the fan is running at high speed.

[0011] In one type of car seat backrest described above, a second mounting plate is provided on one side of the ventilation bag, and the airflow distributor is mounted on the other side of the ventilation bag via several plastic clips that pass sequentially through the second mounting plate and the ventilation bag. This facilitates assembly and improves the stability of the airflow distributor after installation.

[0012] In the aforementioned type of car seat backrest, a fixing frame is embedded in the rear side of the backrest foam. The ventilation bag and air pump are both located within the fixing frame, and a rear cover plate is installed on the fixing frame. The fixing frame and the rear cover plate are made of metal. The fixing frame enhances the structural strength of the backrest foam and facilitates the installation of the rear cover plate. The rear cover plate provides further protection for the massage and ventilation components located behind the backrest foam, such as the ventilation bag, air pump, fan, and airflow distributor.

[0013] In the aforementioned type of car seat backrest, several backrest airbags are arranged in a matrix. This allows the airbags to cover the user's back as much as possible, improving the user's seating comfort, while also making assembly very convenient.

[0014] Compared with existing technologies, the advantages of this car seat backrest are as follows: by embedding several backrest air bags in front of the backrest bubble, embedding the ventilation bag and air pump adjacently in the backrest bubble, and installing the fan and airflow distributor vertically staggered on the ventilation bag, the massage ventilation components are stacked and installed in an orderly manner, thereby improving the structural compactness and assembly convenience of the massage ventilation components in the seat backrest.

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] A type of car seat backrest, reference Figure 1-5The backrest includes a foam backrest 1, with several air bags 2 embedded in the front side of the foam backrest 1. To improve the stability of the air bags 2, they can be further connected by adhesive. The ventilation holes 1a and the air bags 2 are staggered. A ventilation bag 3 and an air pump 4 are embedded in the rear side of the foam backrest 1. A fan 5 and an air distributor 6 are installed in the rear side of the ventilation bag 3. Several ventilation holes 1a are opened on the foam backrest 1 in front of the ventilation bags 3. The surface of the ventilation bag 3 has several ventilation holes 3b that are respectively arranged opposite to the fan 5 and the ventilation holes 1a. The ventilation bag 3 is covered with a sponge cover plate 7. The fan 5 and the air distributor 6 are staggered vertically and both are exposed above the sponge cover plate 7. The air inlets of the air pump 4 and the air distributor 6 are adjacent and connected. The air bags 2 are all connected to the air outlets of the air distributor 6 through air pipes 8.

[0023] During use, fan 5 forces outside air into ventilation bag 3. The surface of ventilation bag 3 has several ventilation holes 3b with a diameter of 0.8-1.5mm. The airflow diffuses through ventilation bag 3 and then through several ventilation holes 1a on the backrest foam 1, flowing evenly out through the perforated leather of the backrest cover (hole diameter 1.2mm, hole spacing 4.0mm), forming an airflow network covering more than 80% of the backrest surface. The airflow directly acts on the contact surface between the user's body and the backrest cover, accelerating sweat evaporation through forced convection and keeping the backrest dry. The airflow distributor 6 is also equipped with… The controller is installed on the air pipe, and a solenoid valve (not shown in the figure) is also installed on the air pipe to control the opening and closing of the air circuit. The controller is electrically connected to the air pump 4 and the solenoid valve to control the opening and closing of both. By controlling the opening and closing status, opening and closing time and opening and closing sequence of several solenoid valves, the air pump 4 can individually, partially or completely inflate and deflate several backrest air bags 2. The pressing pressure generated by several backrest air bags 2 during the inflation and deflation process can be transmitted to the back of the driver and passenger through the backrest cover to achieve massage for the driver and passenger, help passengers relieve physical fatigue and improve the riding experience.
