TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile seat, especially relates to a kind of automobile seat of integrated cushion height adjustment and backrest flip flat function. BACKGROUND
[0002] With the continuous development of automobile industry and the increasing demand of consumers for automobile ride experience, the functionality of automobile seat becomes an important factor to improve the competitiveness of automobile. Consumers not only expect automobile seat to provide comfortable ride experience, but also put forward higher requirements for the diversity and convenience of its function. Among them, seat height adjustment function (referred to as "high adjustment" function) and backrest flip function (referred to as "fold flat" function) become two key functions that attract much attention. In order to realize the "high adjustment" function of seat, the existing technology usually adopts the way of equipping height adjustment mechanism at the lower end of seat frame. However, in the process of realizing height adjustment, in order to ensure the comfort and overall coordination of ride, it is required that the backrest can move together with the cushion, that is, the cushion and the backrest need to be connected together. This connection mode ensures the stability and consistency of seat in the process of height adjustment to a certain extent, but also brings limitations to the realization of subsequent functions. Because the front row backrest cushion and backrest side wing are relatively high, the seat-back interference problem is more prominent when the backrest is folded flat, which leads to the failure of the backrest to be folded flat smoothly. In order to solve this problem, the existing technology generally adopts the way of separate diving of cushion to reduce the interference amount of seat-back. But this way requires that the cushion and the backrest cannot be connected together, otherwise the diving movement of the cushion will be limited by the backrest, and the purpose of reducing the interference amount cannot be effectively realized. Through the above interpretation of "high adjustment" and "fold flat" function, it can be obviously seen that there is a contradiction between the two functions in logic. The "high adjustment" function requires that the cushion and the backrest be connected together to ensure the synchronization and stability during height adjustment, while the "fold flat" function requires that the cushion and the backrest be separated so that the cushion can dive alone to provide space for backrest folding. This contradiction makes it difficult for the existing seat structure to realize both functions at the same time, and cannot meet the demand of consumers for multi-functionality of seat. At present, most of the automobile seats on the market can only realize one of the "high adjustment" or "fold flat" function, or reluctantly take both through complex design and additional mechanical structure, but this way often leads to problems such as complex seat structure, increased cost and reduced reliability.
