Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile seat structure, and particularly relates to a structure and method of a second-row seat of an automobile. BACKGROUND

[0002] At present, most SUV models are five-seater, that is, two sets of seats in the front row and three sets of seats in the back row in an integrated manner. However, with the continuous development of automobiles, the five-seater SUV cannot meet the needs of some families, and six-seater or seven-seater SUVs emerge as the times require. The seven-seater SUV has a larger seating space and can carry more passengers, providing convenience for many car owners. Among the six-seater or seven-seater SUV models, the second-row seats are generally arranged in the form of two separate seats, and a channel for passengers to access the third-row seats needs to be reserved between the second-row left seat and the second-row right seat. Some models arrange the second-row seats in an integrated manner, but this arrangement makes it inconvenient for passengers to access the third-row seats, so most multi-seater SUV models generally choose to arrange two separate seats in the second row and reserve a channel in the middle.
