Device for improving comfort level of automobile seat and increasing sitting space

Abstract

The invention discloses a device for improving the comfort level of an automobile seat and increasing the sitting space, which comprises a seat cushion height adjusting mechanism and a backrest adjusting mechanism. The seat cushion height adjusting mechanism is provided with a shear type lifting mechanism which is arranged between a seat cushion framework and a seat upper slide rail, and the upperend and the lower end of the shear type lifting mechanism are respectively connected with a seat cushion side plate of the seat cushion framework and the seat upper slide rail. The backrest adjustingmechanism comprises a backrest integral adjusting mechanism and a backrest segmented adjusting mechanism. An R point of the backrest integral adjusting mechanism is arranged below an H point, and thebackrest integral adjusting mechanism is connected with the seat cushion side plate through a backrest lower connecting plate 2 and a backrest angle adjuster. The backrest segmented adjusting mechanism is formed by connecting the backrest lower connecting plate 2 and a backrest upper connecting plate 1 and is composed of a motor driving device and a limiting or locking structure. According to theautomobile seat device, the footrest space of passengers in the rear row is increased, the backrest adjusting comfort is high, and different requirements of different crowds for the seat backrest canbe met.
