DETAILED DESCRIPTION

[0031] The utility model will be further described below in combination with the drawings and specific embodiments, so that the person skilled in the art can better understand the utility model and implement it, but the embodiments are not as the limitation of the utility model.​​​​

[0032] As Figures 5-9 shown, the modified seat cushion framework of the embodiment includes a slide rail 11 at the lower part and a seat frame 12 above the slide rail 11, the seat frame 12 is respectively provided with a front transmission piece 13 and a rear transmission piece 14 between the front and rear ends of the slide rail 11, and a modification mechanism 20 for modifying a conventional automobile seat into a zero-gravity seat is installed at the front end of the slide rail 11.

[0033] Specifically, as Figure 10 shown, in the embodiment, the modification mechanism 20 for modifying a conventional automobile seat into a zero-gravity seat includes a bottom frame 21, both ends of the bottom frame 21 are respectively provided with an angle adjustment mechanism, the angle adjustment mechanism includes a mounting seat 22 and a transmission piece 23, the mounting seat 22 is fixedly connected with the bottom frame 21, and the transmission piece 23 is rotationally connected with the mounting seat 22. The modification mechanism 20 for modifying a conventional automobile seat into a zero-gravity seat of the embodiment further includes an angle adjustment driving mechanism for driving the transmission piece 23 to rotate relative to the mounting seat 22.

[0034] In the embodiment, the bottom frame 21 is fixedly installed on the slide rail 11, one end of the front transmission piece 13 is hingedly connected with the seat frame 12, and the other end is hingedly connected with the transmission piece 23, and both ends of the rear transmission piece 14 are respectively hingedly connected with the seat frame 12 and the slide rail 11.

[0035] In this way, the transmission piece 23 is driven to rotate relative to the mounting seat 22 by the angle adjustment driving mechanism, and under the action of the transmission piece 23 and the front transmission piece 13, the height position of the front end of the seat cushion 12 relative to the slide rail 11 can be adjusted, and when it is needed to be adjusted to a zero-gravity state, the height of the front end of the seat frame 12 is higher than that of the rear end of the seat frame 12, so as to meet the requirement of the zero-gravity effect on the inclination angle of the seat cushion.

[0036] Specifically, in the embodiment, the mounting seat 22 and the transmission piece 23 are transmissionally connected through an angle adjuster 24, that is, the angle adjuster 24 in the embodiment is provided as two, and the two angle adjusters 24 are coaxial. In the preferred embodiment of the embodiment, a transmission shaft 25 is provided between the two angle adjusters 24, and in the embodiment, the angle adjustment driving mechanism includes an angle adjuster motor 26 transmissionally connected with the transmission shaft 25. In this way, the transmission shaft 25 is driven to rotate by the angle adjuster motor 26, that is, one transmission shaft 25 is used to drive the two angle adjusters 24 to rotate synchronously, so that the heights of the front end of the seat frame 12 on both sides remain consistent.

[0037] In this embodiment, a rear connector 16 is installed at the rear end of the slide rail 11, and the rear transmission plate 14 is hinged to the rear connector 16.
