It is inevitable that we have to deal with three postures every day, namely standing, lying and sitting. Correct standing posture has a great impact on the health of bones, muscles and joints throughout the body; lying posture will appear in one-third of life, so the correct lying posture, as well as a mattress that can make people sleep comfortably, is also very important; whether the mattress is good or bad is related to sleep health, and whether the seat is good or not, whether the sitting posture is correct, is related to the health of the spine.
The sitting posture is the most commonly used posture of the vast majority of people, and the sedentary crowd is not limited to office workers, but also faces the same problem for the majority of driver friends. The car has become an indispensable tool in our lives, self-driving travel has gradually become a new way of pastime, as the city traffic becomes more and more congested, people stay in the car for longer and longer.
In the car, people often overlook a very important factor, that is, from the moment the driver sits in the car, the driver or passenger will always maintain zero-distance contact with the car seat. At this time, the quality of the seat will directly affect people's riding comfort, and even related to the safety of the people in the car.
What does a good seat look like?
Since the birth of the world's first car in 1885, the seat has undergone more than 100 years of development together with the car. Nowadays, it is not easy for car seats to meet the stringent regulatory requirements while also taking into account the characteristics of "comfort, safety, practicality and beauty".
In order to keep this important auto part competitive, car manufacturers and car seat manufacturers spend a lot of R&D funds on each model to design and develop. According to incomplete statistics, car seats account for about 5% of the overall manufacturing cost of a car and about 6% of the weight of the vehicle.
When it comes to sitting, the most comfortable thing is the half-sitting and half-lying recliner. And when it comes to recliners, we have to talk about the Eames lounge chair. Since its birth in 1956, this recliner, which is known as a classic, has gradually become popular with consumers around the world, making it popular all over the world. In 2003, the Ems recliner was included in the Forest of the World's Best Product Designs and is also regarded as one of the most influential works of art of the twentieth century, a permanent collection of The Museum of Modern Art (MOMA) in New York.
At the moment of electrification and intelligence, the relationship between people and cars has also been redefined, and the space inside the car will also undergo fundamental changes. As an indispensable part of improving the driving experience, car seats are bound to usher in new changes and challenges. For example, the designers of Cadillac LYRIQ jumped out of the shackles of the automotive industrial seat, took inspiration from the Ems recliner, and designed a new seat structure to meet the seat revolution in the new era with a more spacious and comfortable cushion and a more ergonomic design.
We all know that pure electric vehicles due to the need to arrange batteries under the floor, the height of the vehicle floor will increase compared to fuel vehicles, and many pure electric vehicles are generally more difficult to achieve a lower occupant sitting posture. Based on GM's new Ultium Aotony pure electric platform, LYRIQ adopts a SYNERGY platformized seat skeleton design designed for pure electric vehicles, which can meet the comfortable sitting needs of different height models of the Ultium Aoteneng platform.
The LYRIQ seat skeleton adopts a patented four-link low-sitting design, which achieves the industry-leading low-sitting height design, allowing the driver and occupants sitting in the front row to achieve the low sitting posture that can only be found in sports luxury cars on the SUV, and at the same time, they can also enjoy the ample front head space brought by the SUV.
In addition to the feeling of sitting low, the seat material of LYRIQ is also very worth mentioning. The LYRIQ seat fabric is made of GREEN MATERIALs certified by the GLOBAL Recycled Standard and Nuuvous materials, and the high-end is made of NAPA leather, which not only ensures ventilation and breathability, but also has good rebound and support, providing passengers with a luxurious and comfortable ride like a recliner.
In addition, LYRIQ's seats have a wider and thicker seat cushion by optimizing the section of the seat, with a cushion width of 542mm, and the thickness of the cushion and backrest foam material MTM (Meat to Mental) is also increased by 20% compared to the previous generation. The foam adopts a high-density, high-resilience design, and the middle layer is made of Muller 3D mesh material, which is as close as possible to the curve of the occupant's body and provides a more comfortable riding experience for the occupants.
For seat research and development, engineers need to face many challenges, in addition to fabrics, processes, there are many problems in materials, mechanics, ergonomics and other aspects to solve. Although it is a global model, cadillac LYRIQ also conducts multiple rounds of targeted comfort road test evaluations for Chinese consumers' fat, thin, tall and tall and preferences. Only by understanding the physical preferences of Chinese consumers can we design excellent seats that meet the needs of the Chinese people.
All seats should be covered
The LYRIQ vehicle, which is not small in size, has a length of more than 5 meters and a wheelbase of nearly 3.1 meters, which brings advantages to the driving space in the car that traditional fuel vehicles cannot reach, and also provides greater possibilities for the design of the LYRIQ rear seats. The LYRIQ rear row adopts the adjustable large backrest angle design, the design position backrest angle reaches 25°, and has a backward adjustment stroke of 2.5°, so that the rear backrest backrest angle can reach up to 27.5° comfortable sitting posture, exceeding the mainstream competitors in the market 2°. This adjustable seat backrest angle reduces the pressure on the waist during long rides.
In terms of technical configuration, the front seats of the LYRIQ support 14-way adjustment, including 4-way adjustment of the waist support and 2-way adjustment of the headrest, while the LYRIQ seats also have the functions of massage, ventilation and heating, ensuring that the driver and occupants can sit comfortably from the moment they enter the cockpit.
Not only that, LYRIQ's driver's seat supports memory function, through the seat personalized memory storage settings, the driver can set the storage of seat posture according to personal habits and preferences. Four of the 19 speakers are placed in the headrest position of the main co-pilot, which not only allows the front passengers to listen to the surround sound, but also plays the required sounds alone, such as: the main driver's headrest can play navigation voices so that it does not interfere with other passengers.
In terms of critical safety, the car frame or car structure fundamentally determines the safety of the car seat. The interior structure of the early mainstream seat was a coiled spring, with comfort as the main starting point. Today, most cars are starting to use one-piece full-beam seats.
The seat frame can be roughly divided into two parts: the cushioning frame and the rear frame. Due to the relatively large volume of the seat, it is often necessary to consider lightweighting when designing, provided that safety cannot be lost. The easier way is to reduce the metal material and use a thinner and lighter material, or rely on punching holes to reduce weight.
The skeleton of the LYRIQ seat, through the use of a large number of 980Mpa high-strength steel to replace the traditional ordinary steel, to achieve lightweight design, improve seat safety at the same time, but also to meet the North American (FMVSS202), The European Union (ECE248) and China (GB15083) market the world's highest safety level.
Master observation
Due to the needs of the times, we have seen cadillac LYRIQ's consideration of seat details, continuous innovation in design innovation and comfort experience, and I believe that in the end, we can also get an excellent riding experience. It is undeniable that in addition to the familiar American luxury, Cadillac is still insisting on innovation, and the result of innovation is to allow users to better enjoy the humanized experience and texture brought by scientific and technological progress. At the same time, this is also LYRIQ's in-depth insight into the trend of travel consumption upgrading, and the best reflection of the in-depth cultivation of luxury pure electricity.
