Car seat skeleton (1)
car seat skeleton (1)When the automobile was first invented, the seat was just a small bench. Later, due to the needs of safety and comfort, the seat gradually evolved into a mobile sofa.To this day, more adjustment mechanisms have been added to car seats, and the functionality has become richer and richer.
Why do car seats need a skeleton?
Bones play many indispensable and important roles for vertebral creatures such as humans. Among them, providing overall structural support and organ protection for living objects is the most important point. Car seats also have their own “skeleton” structure.The role of the seat skeleton is to withstand loads, transmit torque, increase stability, and install various functional parts. For parts such as seat foam, seat cover, electronic parts, and plastic parts that cannot be suspended inside the seat out of thin air, the skeleton is the carrier for installation and support.Car seats not only provide comfort for the driving experience, but also an important part of safety and security. For this reason, the skeleton structure of the car seat determines the safety performance, comfort performance and economic performance of the whole chair product, and it has also received more and more attention.
Pay attention to the front and rear skeletons
As one of the safety components of a car, the seat, the strength of its skeleton, plays an important role in the safety of the vehicle in use.A good skeleton must be fixed and protect the occupants to maintain a specific posture when the car is hit, so that other safety parts, such as seat belts, airbags, etc., can give full play to their due protection functions.Today's passenger cars are usually equipped with two to three rows of seats, so according to the seat installation position, they will be divided into front and rear seat skeleton assemblies, and the requirements and functional structure will be different.
Front seats
For ordinary vehicles, if calculated according to the frequency of use, the seats in the car are the most used and functional, and the location where members are most vulnerable to accidents is usually located in the front of the vehicle. In addition, various models have higher requirements for the platformization of the front seats, so the front seats are the most important and the most difficult part to develop in the vehicle seats.At present, the structure of the front row skeleton is mainly concentrated in three types: full-tube skeleton, sheet-tube skeleton and full-sheet skeleton.
The full-tube skeleton structure is the simplest and the lowest cost, but only a small part of the basic parts made of stamped sheet metal and a large number of tubular materials make its performance the worst; the performance of the full-tube skeleton structure is favored by European and high-end models. The entire skeleton is composed of sheet metal stamping and welding, with the best performance and the highest cost.The cost, performance and complexity of the sheet-tube skeleton structure are between the two. It is mostly selected for Japanese and Korean models. It has the flexibility to adapt to most shapes and the cost is slightly lower. It has become the main structure type selected by most car companies.
