Air bag car seat

This creation is a type of car seat, especially an air bag type car seat that uses an air bag to replace the sponge pad in the conventional seat, allowing the seat to be adjusted according to needs to improve comfort and reduce weight.

The car seat has a considerable contact area with the human body. In order to enhance the support and comfort of the seat to the human body, the general seat is a sponge pad made of elastic foam material on a support structure (skeleton). Body, and outside the support structure and the sponge body, a layer of outer cover that can beautify the appearance is coated with a material such as leather material or carbon fiber, and the main cushion structure can be formed by the shock absorption and soft cushioning effect of the sponge cushion body. When the user is riding, the hips and back can be more comfortable.

Furthermore, for long-distance drivers, excessively soft seats can cause excessive fatigue on the user's waist and spine, and a sore back, which can cause distraction problems. Therefore, some car seats are adjusted in the seat back. Structure, the adjustment structure mostly uses a mechanical push rod or cam device to make a simple adjustment of the back of the car seat, so that the seat is fed back to the back of the human body is relatively stiff, providing proper support of the back and waist to reduce physical fatigue.

However, the sponge pad body is of a fixed volume and shape. It is usually manufactured in a general specification that can conform to most human body types.

In the environment, the driver will shake more and more, and the above-mentioned mechanically operated adjustment structure will increase the total weight of the seat, which is contrary to the light weight concept pursued by the automobile industry.

In order to solve the above problems, the current car manufacturers are based on different vehicle types or different controls. Oriented vehicles to design car seats. For example, a car that is generally suitable for urban driving has a car seat that is generally designed to be softer, while a vehicle that emphasizes performance orientation generally has a better car cover. This kind of vehicle design with different types of vehicles or different steering directions can solve the requirements of some drivers for different car driving habits, but it does not really solve the same car. The driving environment needs, and the cost will increase for the car manufacturer, so that there is obviously much room for improvement in the design of the existing car seat.
