Middle seat framework with electric easy-entry function and control method thereof

Abstract

The invention discloses a middle seat framework with an electric easy-entry function and a control method thereof. The framework comprises a seat frame and a backrest installed on the seat frame, wherein a sliding rail system is arranged below the seat frame and comprises a lower sliding rail, an upper sliding rail connected to the lower sliding rail in a sliding mode and a sliding rail motor driving the upper sliding rail to slide, and the sliding rail motor drives the lower sliding rail to slide; the seat frame is installed on the upper sliding rail through a linkage mechanism, and an executing mechanism and a locking mechanism are arranged between the seat frame and the upper sliding rail; wherein the locking mechanism is used for enabling the seat frame to be fixedly kept on the upper sliding rail. The executing mechanism is used for controlling the locking mechanism to unlock and driving the seat frame to move through the linkage mechanism so that the rear end of the seat frame can be lifted upwards relative to the upper sliding rail. In the control method, the sliding rail motor and the lifting motor execute actions at the same time, and the rear end of the seat frame can be lifted to the highest position; then the upper sliding rail slides to the foremost position, the whole seat is automatically controlled to incline forwards and move forwards, the convenience of passengers entering the back row is remarkably improved, and a high-grade sense is achieved.

Description

technical field [0001] The invention relates to the technical field of car seats, in particular to a middle-row seat frame with an electric easy-entry function and a control method thereof. Background technique [0002] For some SUVs and business models, there are usually three rows of seats in the car.
