Related knowledge of the front frame of car seats
With the development of the economy, cars as a means of transportation have been popularized in almost every household. Whether it is office workers or school workers, they can see and use it almost every day. Today, the editor would like to talk to you about the professional term "front frame of car seats";
The seat on the car is one of the indispensable parts of the car, especially the bus. The bulge designed at the waist and back of the car seat can best reduce the pressure on the waist. The hard plastic seat has a strong structure and a long service life, but it is not comfortable to ride. Therefore, the production and R&D personnel of car seats hope to have a car seat frame mechanism that is easy to install and easy to adjust, which can well support the main body of the car seat, and is conducive to the production of manufacturers and easy for car users to adjust. The car seat frame platform is the basic component of the seat assembly. Passenger car seats generally have 2-3 rows, so they are distinguished according to the position, including the front and rear car seat frames. The front and rear car seat frame structures are completely different.
What is the function of the front frame of the seat:
1. The function of the front frame of the seat is to bear load, transmit torque, and increase stability. It is very similar to human bones.
Seat foam, seat cover, electronic parts, plastic parts cannot be suspended in the air inside the car, so the frame is the installation carrier of seat cover, seat foam, electronic parts, plastic parts and other parts.
The quality of the seat frame directly determines the safety, comfort and economic performance of the whole seat. Therefore, the frame is an important component in the car seat.
2. The most frequently used position of the car and the most vulnerable position of the occupants is in the front row, and the platform requirements of the front seats of various models are high. Therefore, the front seat is the most important and more difficult to develop in the whole car seat.
Common passenger car front row frames are: full tube structure, sheet tube structure, full sheet structure.
Full tube seat front row frame: It is estimated that the basic parts are all tube materials, and only a few places use stamping sheet metal. This type of frame structure is simple and has the lowest cost, but its performance is also the worst.
Sheet tube seat front row frame: The frame only uses pipes at the backrest headrest, and only needs to change the pipes to match most shapes. Its cost, performance and complexity are moderate, and it is the most widely used frame form for domestic mainframes.
Full-sheet front frame of seats: The entire frame is made of sheet metal stamping & welding. This type of frame has the best performance and the highest cost. It is currently widely used in some joint venture imported models.
The sizes of the front seats of various models are very similar, and there are only four fixed points of the slide rails connected to the body. Therefore, the front seats are easier to realize platformization, and major seat manufacturers have also developed their own front seat frame platforms.
The method of realizing the front frame platform of seats is to design each function into a module, and then install the corresponding module for the required function. In this way, most of the parts of the frame can be universal.
