Pertama-tama, tata letak kursi harus masuk akal. Ukuran posisi pemasangan kursi sangat penting, yang secara langsung mempengaruhi kenyamanan dan kenyamanan pengguna. Pengaturan tempat duduk harus mencerminkan persyaratan ergonomis.
The shape of the second seat must conform to the physiological functions of the human body. If the driver's riding posture is not ideal, it is easy to get tired or even cause strain. Therefore, the driving seat positions designed by major Japanese, European and American car manufacturers have reference data for basic posture, head, shoulders, arms, abdomen, legs and other movement spaces, which cannot be arbitrary.
The third seat should have an adjustment mechanism (car seat angle adjuster, seat rail). There are differences between men and women, and the seats (especially the driver's seat) must be adjustable. There are adjustments to fit most body sizes.
Kursi keempat harus memiliki karakteristik getaran yang baik. Meskipun lantai banyak bergetar saat kendaraan bergerak, kenyamanan yang baik dapat diperoleh di kursi berkat pegas kursi mobil. Jika kinerja pegas tidak baik, kenyamanan mobil akan buruk.
Kursi kelima harus sangat aman dan terjamin. Kursi mobil, sabuk pengaman dan airbag bersama-sama merupakan perlindungan keselamatan bagi penumpang. Keteguhan kursi mobil itu sendiri, keandalan koneksi dengan bodi, dan kekuatan sandaran semuanya memiliki peraturan industri dan standar pengujian.
