The chest rod includes a circular arc segment. Meshing gear teeth are on one side of said chest rod. Meshing gear teeth are on the inner circular arc side of the chest rod which is like circular arc; and the other end of the chest rod goes through the driving gear box under the seat; a driving gear is placed in the driving gear box and its teeth fit the meshing gear teeth of the chest rod; rolling wheels are placed on both sides of the driving gear; a rolling wheel to support the chest rod is placed on the outer circular arc side of the chest rod.

A driven gear box is placed in front of said driving gear box; a driven gear is placed in the driven gear box and the teeth of the driven gear fit the meshing gear teeth of the chest rod; rolling wheels are placed on both sides of the driven gear; a rolling wheel to support the chest rod is placed on the outer circular arc side of the chest rod. The driving gear is connected with the axle of a driving motor; the driving motor is controlled by controller. The height of said driving gear box and driven gear box is controlled by the hydraulic extensible pipes under them.

The following is another technical scheme:

It includes a chest cushion which is a plank; an extensible chest rod is connected with the bottom of the chest cushion, the extensible chest rod stays on the back, close to or under the seat in front of the passenger after it is pulled back; a headrest which is a plank is placed on the back of the seat in front of the passenger, or above the extensible chest rod and connected with the chest rod.

An extensible chest rod is attached to the back of the seat in front of the passenger by magnet, snap-fit or hook & loop fastener after it is pulled back.

The extensible chest rod is hydraulic. The extensible chest rod is slid into under the seat through rail after it is pulled back. The angle between said extensible chest rod and the ground is adjusted by a hydraulic extensible pipes connected with them. The ground end of the extensible chest rod is connected to the ground or other parts connected to ground by hinge.

The advantages of this invention are: passenger doesn't need to assemble, just press buttons to drive motors to raise chest cushion, the chest of the passenger is placed against the chest cushion by leaning body, his head is rested on the headrest, then sleep comfortably; if the passenger doesn't want to sleep, he can press button to lower the chest cushion to be close to the seat bottom, the chest cushion will not impede the movement of the passengers. In addition the length adjustment of the chest rod is gradual, so that it is easy for user to find the most comfortable position.

The chest rod 5 includes a circular arc segment; meshing gear teeth 51 are on one side of the chest rod 5. The meshing gear teeth 51 are on the inner circular arc side of the chest rod 5 which is like circular arc; the other end of the chest rod 5 goes through the driving gear box 7 under the seat 3; a driving gear 8 is placed in the driving gear box 7 and its teeth fit the meshing gear teeth 51 of the chest rod 5; rolling wheels 9 are placed on both sides of the driving gear 8; a rolling wheel 10 to support the chest rod 5 is placed on the outer circular arc side of the chest rod 5. A driven gear box 6 is placed in front of the driving gear box 7. There is a driven gear 11 in the driven gear box 6 and the teeth of the driven gear 11 fit the meshing gear teeth 51 of the chest rod 5; rolling wheels 13 are placed on both sides of the driven gear 11; a rolling wheel 12 to support the chest rod 5 is placed on the outer circular arc side of the chest rod. Rolling wheel 12, 10 can reduce the friction force to the chest rod 5 when the chest rod 5 is moving.

There is a connector 61 to fix the relative positions between driving gear box 7 and driven gear box 6.

Referring to FIG. 4 and FIG. 5 (Embodiment 2):

Head rod 16 is connected on the upper side of the chest rod 5. Head rest 17 is connected to the upper end of the head rod 16. The axle of driving gear 8 is connected with the axle of the driving motor; the driving motor is controlled by a controller.
