Car seats are generally composed of surface materials, fillers, skeletons, adjustment devices, and body connectors. The first step in car design is not the concept map or the effect map. Designing the seat is the first step in car design.
Is this different from what you think? But it is true. The reason why the seat should be designed first is that the seat can be designed according to the H point of the human body, including the position, shape, thickness, adjustable angle, etc., only after the driver's sitting position is determined. Only after the sitting position is determined, the positions of the steering wheel, pedal, center console, door, etc. can be finalized.
If you want to design a comfortable seat, you know that the basic form and concept are not good. It is important to know the specific human data, which is the "ergonomics" we often hear.
For the layout of the seats, each company has its own standards and focus. In general, however, there are three main factors: comfort, the driver's field of view, and the ease of operation of the area that the driver can reach.
For most drivers, the most common angle range for the most comfortable human body is shown in the figure (Note: H point in the figure below refers to the connection center point between the human torso and the thigh, on the body layout, H point It is the reference point for the positioning of the human body.)
For the form of the seat, the seat back is designed to have a concave and convex shape. Because the spine of the human body is naturally S-shaped, if you want to sit comfortably, the seat should have strong support for the chest, back and lumbar spine.
Car seat design, to understand these points: normal sitting position can reach all the buttons on the center console, to be suitable for different heights of the driver, easy to control the throttle, brake pedal, to avoid "arms" around the arms and body parts The comfort of the seat lies in the requirement of dispersing the gravity and satisfying the comfort, minimizing the thickness of the backrest and lying down if lying down.
