comes to ordinary consumers It is said that the overall experience of a car first comes from the seat and the performance of the seat determines whether the entire experience process can continue. It seems that ordinary seats are actually not ordinary. From design to mass production, it is necessary to consider the impact of comfort, weight cost, interval size, molding, production efficiency, durability, and various national security standards.
Because there are too many elements involved, many ordinary consumers cannot make the right judgment on the car seat, some think that soft is good, some consumers think hard is Great. Is this really true?
Modeling is the first step of judging the performance of the seat
seat design is The first step in the entire car design, once the type of model is determined, the seat can be determined, and the driver and the occupant are constantly expanding the dashboard, steering wheel, pedal, handle, and central interior design, so the seat is sitting It is often first considered.
If it is a SUV model, the driver’s sitting position needs to be more tailed; if it is a sports car, the driver is sitting It is often necessary to short. However, in the past, China’s car brand does not have the strength of a separate design seat. The strength includes a seat frame (spring structure and all-in-form type), including seat spring, liner, surface material, and sewing assistance Material, etc. The consequences of this is that many Chinese brands often use European manufacturers’ maturity programs.
This approach is advantageous, although it can meet the performance requirements of all aspects, but European manufacturers are designed with the object to be more European body, not fully suitable Chinese consumers, so China’s car brands need targeted adjustments.
Even so, Chinese people have fat and thin, so automakers need to design a set of human data templates, that is, although not 100% is suitable. Various columns, but at least to meet certain proportions, the human engineering data collection is opened.
Sitting on the seat, the final stable posture is finally sitting, sitting with the thigh cutting and horizontal lines 10 ~ 30deg; the best tangent Vertical into 20 ~ 30deg ;. This is to meet the comfort while meeting comfort, it can limit the overemployment of the lower body when chasing. At present, there is an apparatus that can reappear the cushion of the knee in the changing, thereby playing a stronger limit sliding on the lower limbs. In order to prevent the pelvis, the spine should be presented, the support of the waist should be near the third lumbar vertebrae of the member, the support is too weak to form a cat back, and the abdomen is easily fatigue. In contrast, if the support is too strong, it is easy. The abdomen is too forward, and the upper support is insufficient.
Therefore, the first step of the evaluation seat is to feel the support of the chest, waist and the thigh, especially It is the third lumbar spine of the waist, and the chest is concentrated near the shoulder blade. The second step is to keep the horizontal line, observe the road, distant sky, and car information. Instrument disk information, the central control display is preferably maintained below 15deg; nearby, if information is read, it is necessary to lower more than 35deg; then the driver’s attention is too large, increase the probability of accident, the front windshield is required to keep it in terms of sight. 25DEG; above, too low to depress.
Secret of zero gravity seat
After the car competition is gradually intensified, the automotive manufacturer Started to introduce a more friendly seat for the driver, in which the concept of “zero gravity seat” is referenced by many brands, such as new MG5.
in MGIn the information preparation of the new MG5, the MG5’s seat highlights are written in this: MG5 seat is bonded in the Asian human curve, with a large area of zero-gravity filled, realizing uniform distribution of human pressure, soft, bottom, solid, tens into a long-distance Driving, 92mm full fit high side wings. What did these so-called advantages come to the end?
With regard to the Asian curve, there have been differences in the Americas, Europe, Asia, and African people, and local car companies should try to distinguish. 
20mm zero-gravity filling on the actual performance of the seat is greater. At present, the mainstream compact cars, MG5 use 20mm zero-gravizable layer, and the sylphy is 10mm, the emot GL and Lang Yi did not.
The car frame will cover a set of pads, that is, the mold is first synthesized by the mold, and then the soft filler is used, the purpose is to increase the seat shape and lift the seat. Bodybent and feel, then cover the surface material (fabric or leather), enhance the seat quality. Zero-gravity fill is part of contact with the frame.
Zero-gravity filling is a critical effect on the seat lies in it. Physical pressure is evenly dispersed. After sitting down, most of the human body is transmitted to the sitting bone. If the bone is stressed, it is easy to cause “ass soreness”, so in order to reduce the pressure of the sciament, the bottom filler material can not be in good ending pressure, also Requires dispersion pressure.
If the car seat should refer to the highest body pressure near the saddle joint of the feeling, it is best to support most of the body weight. Legs forward, gradually reduce body pressure pressure. The body pressure distribution near the thigh mainly considers driving habits, not only do not affect the pedal, but also support the thigh during normal driving.
At this point, many consumers have begun to think that soft seats can be effective and dispersed, which is a better choice. In fact, excessive soft seats cannot guarantee long-time ride posture. If it is a long-distance driving, the soft car seat is easy to oppress the abdomen and fatigue, so excellent seat needs to change the posture when the occupant is particularly fatigue. That is to say that the seats that keep the body have better soft seats that make the members’ body sink. This is also the content that the MG5 seat “surface is soft, the bottom is solid”.
92mm bonded to the flank, in fact, involving the control of riders often talking, that is, the maintenance of the car seat. A excellent seat should be in the vehicle turn and a spiral road, there is a performance that can indeed maintain a member sitting position, thus dynamic adjustment of ride comfort.
Of course, this part of the performance is not completely realized by the flank, but through the seat back energy to support the members of the pelvic and the side shape and hardness of the upper body, it is only the side wing. Can effectively improve this performance.
In fact, the 92mm wing height is exaggerated, and the general sports cars or high luxury SUV will be the case.
Collision Safety is the last
car frame or car structure Fundamentally determines the safety of the car seat, the early mainstream seat is constructed as a roll spring spring, and “comfort” is the main starting point. Today, most cars began to adopt a total all-round seat.
The seat frame can probably be divided into two parts: the buffer frame and the rear frame. Since the volume of the seat is relatively large, it is often considered lightweight during design, the premise is that it is not possible to lose safety, and the relatively simple method is to reduce the metal material, and the thin and lighter material is used, or rely on punching weight loss. However, this requires a lot of simulation calculation.
In the accident, the vehicle in the fast driving quickly stopped, and the adult body was quickly forwarded, and the seat was pulled forward, and then the help of the seat belt, the body quickly retired back to the seat back. In order to simulate this project, the car seat often employs the seating impact strength, the safety belt strength, and satisfying the required passenger ratio, the backward load of the backbone, and the backward load of the skeleton.
In a collision test of a new MG5 seat, the MG5 seat can meet the C-NCAP five-star standard anti-whipping requirements, withstanding the impact of 36 kg of luggage. The strength of the seat belt can withstand 16200N + 20 times self-weight, collision satisfies 50-95 percent passengers, frontal seat skeleton forward limit load 1500 nm, front seat skeleton backward load 2500 nm.
The performance ensures that the seat is sufficiently stable, and the passengers should be protected from safe.
Yason Nodes
If it is just simple judgment A car seat is good, only need to start from the car, feel the force of the chest waist and abdomen. If there is data support, you can feel the body pressure distribution, and finally query the specific security data of the seat, so you can do it in your heart. Availability, but the test is not so far, there is durability, vibration, up and down cars, etc., but these needs to slowly feel in daily life.
