46 split-folding refers to folding down 40% of the entire rear seat, approximately the space occupied by one person. 64 split-folding means folding down 60%, and it cannot be fully folded down. Here is a detailed introduction about car seats: Overview: Car seats are the seats used when riding in a vehicle. They can be roughly divided into different parts: Front seats: Headrest, backrest, seat cushion, (armrest). Rear seats: (headrest), backrest, seat cushion, side wings, (armrest). According to different materials, they can be roughly divided into leather seats, fabric seats, etc. Requirements: The arrangement of seats in the entire cabin should be reasonable, and the driver's seat must be in the optimal position. The shape design of the seats must conform to human physiological functions. The seats must be safe and reliable, with sufficient strength, stiffness, and durability. There should be reliable locking devices to ensure safety.

I just bought a new car with a 40/60 split-folding rear seat design, where both the 40% and 60% sections can be operated independently. Generally, this allows the rear seats to fold completely flat. For example, I often transport large items like bicycles or moving boxes—just pull the release loops on the seats and fold down the two sections step by step to create a fully flat cargo area in the rear, which is super convenient. Don’t worry about the operation; most vehicles like SUVs and hatchbacks support full flat-folding, but some sedans may have trunk opening angles that affect the overall flatness. It’s recommended to first try removing the headrests to avoid obstruction. This feature has saved me countless times—whether it’s loading tents for weekend trips or groceries from the supermarket, I no longer need to rent a car.

As a family user who frequently travels with kids, I pay special attention to whether the 40/60 split-folding rear seats can truly lie completely flat when choosing a car. In practical use, the 40% and 60% divided sections can indeed be folded down sequentially to create a large space for strollers or suitcases. The operation is very intuitive: first unlock the 60% side, then push down the 40% section—just remember to check that the floor mat is even to prevent items from sliding. The advantage is the flexibility; you can fold down only half to place miscellaneous items while still seating passengers in the back. However, be aware that some older models might have linkage wear preventing full flatness, while newer models don’t have this issue, making them safer and more worry-free.

Let me talk about some technical details but keep it simple. The 40/60 split-folding rear seat design means both the 40% and 60% sections can be folded down to a completely flat state. The key lies in the floor-mounted hinges and latch systems - most modern cars like Volkswagen or Toyota have optimized this structure. When operated correctly, it forms a seamless large flat surface. I've tried folding all seats down for long trips to fit sleeping bags for camping - doubling the space feels amazing. However, there are slight variations between brands - American cars might leave small gaps compared to the tighter fit of Japanese models, but it doesn't affect practicality.
