Description

air bag car seat

technical field

The invention relates to a car seat, in particular to an air bag type car seat which uses an air bag to replace the sponge cushion body in the existing seat so that the seat can be adjusted according to requirements to improve comfort and reduce weight.

Background technique

There is a considerable contact area between the car seat and 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 supporting structure (skeleton). Body, and outside the supporting structure and sponge cushion body, use leather or carbon fiber cloth to cover a layer of outer chair cover that can beautify the appearance. The main buffer structure is formed by the shock absorption and soft cushion effect of the sponge cushion body, so When the user rides, his buttocks and back can be more comfortable.

Furthermore, for drivers who drive long distances, riding on an overly soft seat will cause excessive fatigue in the waist and spine of the user, and back pain, resulting in distraction problems. Most of the adjustment structures use mechanical push rods or cam devices to simply adjust the back of the car seat, so that the seat can feedback to the back of the human body to be stiffer, provide proper support for the back and waist, and reduce physical fatigue.

However, the sponge cushion body has a fixed volume and shape. It is usually designed to meet the general specifications of most people. It cannot adjust the curvature or improve the coverage according to the individual body shape. If driving on a curve or mountain road is more intense In such an environment, the driver will shake more severely, and the above-mentioned adjustment structure that operates mechanically will relatively increase the total weight of the seat, which is contrary to the concept of light weight pursued by the automobile industry.

In order to solve the above problems, car manufacturers currently design car seats according to different types of vehicles or vehicles with different handling orientations. For example, the car seats of RVs that are generally suitable for driving in urban areas are usually designed to be relatively soft; while the car seats of performance-oriented vehicles are usually better covered. This method of designing car seats for different types of vehicles or vehicles with different handling orientations can certainly solve the requirements of some drivers on the design of car seats due to different driving habits, but it does not really solve the problem of the same car in different situations. The needs of the driving environment, and the cost will increase for the car factory, so there is obviously a lot of room for improvement in the design of the existing car seats.

In order to improve the comfort of the car seat, the inventor once developed a structure in which a plurality of air bags are partially embedded on the sponge pad of the car seat, so as to use the intermittent expansion and contraction of each air bag to treat the driver's back. Massage can also use the pushing pressure of the air bag to produce a local point-like support effect. Although this design can make a slight change in the softness of the car seat, it is still not enough to fully use the air bag to replace the sponge pad, especially if the inflatable device is to inflate and adjust a large number of multiple air bags at the same time. , requires a considerable air pressure, not only the specifications of the general air pump cannot load, but also lead to the problem of increased energy consumption of the car or insufficient inflation.

In view of this, the inventor has accumulated many years of research and practical experience in related fields, and specially invented an air bag car seat to solve the problem that the existing air bag is not easy to inflate, and the sponge cushion cannot be made different according to the demand. adjustment problem.

Contents of the invention

When the controller turns on the inflation mode of a certain inflation and exhaust valve, the air in the high-pressure gas cylinder flows into the air bag through the inflation and exhaust valve, which can inflate the air bag to provide support to the user.

When the aforementioned pressure detector detects that the pressure of the air bag exceeds the value stored in the memory of the controller, the controller will issue a control signal to open the exhaust mode of the filling and exhaust valve and close the communication state with the high-pressure gas storage cylinder, so that the gas The air in the bag is discharged to the outside through the filling and exhausting valve.

Conversely, when the aforementioned pressure detector detects that the pressure of the air bag is lower than the value stored in the memory, the controller controls the high-pressure gas cylinder to inflate the air bag. After such repeated operations, the air bag can be adjusted to the most comfortable state for the user, providing proper support and coverage.

During implementation, the internal memory of the controller has a variety of use state modules that can respectively control the saturation of each air bag by default. The use state modules include: sports driving state, long-distance driving state, and urban driving state. For example, in the sports driving state, the air bags located on the outside of the user's arms and thighs are inflated to make the seat concave in the middle and convex on the left and right sides, so that the user has a good package for the body when riding. In the long-distance driving state, the air bag at the back position is inflated to make the seat feedback to the back of the human body stiffer, providing proper support for the back and waist, and reducing physical fatigue; In the driving state of the zone, when the user is sitting on the seat, the air bag has a shock-absorbing and soft cushioning effect.

During implementation, the high-pressure gas storage cylinder includes a regulator that can automatically adjust the inflation pressure of each air bag, and a pressure indicator that can feed back the internal pressure of the high-pressure gas storage cylinder to the controller. The regulator can adjust the pressure of the high-pressure gas storage cylinder to inflate each air bag to avoid damage to the air bag caused by excessive output air pressure at the moment of opening; and the pressure indicator can feed back the pressure to the controller. If the signal of the pressure indicator is pressure Insufficient, then the controller activates the inflation device to inflate the high-pressure gas cylinder.

During implementation, the high-pressure gas storage cylinder is further equipped with a safety pressure relief valve that can automatically release pressure beyond the set pressure, so as to avoid excessive internal pressure of the high-pressure gas storage cylinder when the controller, inflation device or other components fail.

During implementation, the inflation device can be a vacuum pump or an air pump.

During implementation, the inflation device can also be the original electronic vacuum pump (Electric vacuum pump, EVP) on the vehicle, and this embodiment is more suitable for electric vehicles.

During implementation, the supporting structure of the car seat is in the form of a concave central part and relatively convex left and right outer sides; multiple airbags are arranged on the supporting structure in a form where the central part is concave and the left and right outer sides are relatively convex, so that the car seat Takes on a more enveloping form.

Furthermore, in addition to conforming to the seat specifications of general Volkswagen RVs and recreational vehicles, the car seat's support structure specifications further include racing seats or child safety seats during implementation, so that the application of the present invention The scope is wider.

Compared with the prior art, the present invention replaces the sponge cushion in the existing seat with an air bag, so that the seat can be adjusted according to the individual body shape to improve comfort and reduce weight, and the user can choose different uses according to the driving road conditions The status module adjusts the saturation of the air bag, so that the air bag can provide proper support or coverage to the user, and solve the problems that the existing air bag is not easy to inflate and the sponge pad cannot be adjusted according to the needs.
