This seating configuration, commonly found in Chevrolet trucks and vans, refers to a bench seat where the backrest is split into two sections: a 60% section and a 40% section. This design allows for independent folding of either section. An example is found in many Silverado and Colorado models, offering a blend of passenger capacity and cargo flexibility within the cabin.
The importance of this design lies in its ability to adapt to various needs. It provides the comfort of a bench seat with the added benefit of accommodating both passengers and longer items simultaneously. Historically, bench seats were standard in many vehicles. The split-folding design represents an evolution, enhancing the practicality of the traditional bench by offering increased versatility for work and leisure.
