Easy-to-operate travel sleep bracket

Abstract

An easy to operate sleep support frame for travelling is disclosed. The support frame includes a movable and curved chest rod which can move from a passenger's chest to the bottom of the seat; a chest cushion connected with the chest rod; and a headrest connected with the chest rod. The headrest can be placed in the back of the front seat or above the chest rod. The chest rod includes a circular arc segment with meshing gear teeth on the inner circular arc side of the chest rod. One end of the chest rod goes through the driving gear box under the seat to be driven by a driving gear box. The passenger can press a button to drive motors to raise chest cushion, and press the button to lower the chest cushion to be close to the seat bottom if the chest cushion is not used.

DETAIL DESCRIPTION OF THE INVENTION

(12) Referring to FIG. 1, FIG. 2 and FIG. 3, an easy to operate sleep support frame for travelling (Embodiment 1) includes:

(13) a movable and curved chest rod 5; and a chest cushion 4 which is a plank and is connected with the chest rod 5; and a headrest 2 which is a plank and is placed in the back of the seat which is in front of the passenger. 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.
