During described seat maintenance sitting posture: described support bar is positioned at above described seat board as handrail;
When described seat keeps lying appearance: described chair back layback certain angle, described support bar forwards to below the chair back and is supported on ground.
In the utility model better embodiment, when described seat keeps lying appearance, the vertical line that described support bar free end the is corresponding vertical line corresponding with described chair back free end overlaps, or vertical line corresponding to described support bar free end is positioned at the outside of vertical line corresponding to described chair back free end.
In the utility model better embodiment, described hinged all realized by hinged mechanism.
In the utility model better embodiment, in described hinged mechanism, it is provided with gear and the ratchet with described gears meshing.
In the utility model better embodiment, described ratchet is connected with release button, and described release button can move described ratchet makes ratchet engage with gear disengaging.
In the utility model better embodiment, two described support bars are separately positioned on described chair back dual-side.
In the utility model better embodiment, described support bar comprises scalable the first bar linked together and the 2nd bar.
In the utility model better embodiment, it is domatic that described 2nd bar free end is provided with elasticity.
In the utility model better embodiment, between described first bar and described 2nd bar, it is provided with locking means.
The utility model solves in background technology the defect existed, and the utility model possesses following useful effect:
(1) between the chair back and seat board, seat board and leg lean between and hinged mechanism is installed between the chair back and support bar, it is achieved above-mentioned angular setting between any two and fixing.
(2) on the basis of existing student's seat, support bar has been installed as handrail, it is achieved the sitting posture of safety and comfort more.
(3) support bar rotates to chair back rear, it is possible to realize the Gravity support to the chair back, and one is dual-purpose.
(4) what leg leaned on arranges and can support for the pose that leg provides more comfortable.
(5) arrange in hinged mechanism the gear of engagement and ratchet can after ensureing to rotate to an angle angle fixing, the release button simultaneously arranged can move ratchet, ensures that both depart from engagement, facilitates translation-angle.
(6) first bars and the 2nd bar stretch to arrange and make support bar as handrail or as adjusting to applicable length during strut member.
(7) the domatic employing rubber of elasticity, it is possible to play effect that is anti-skidding and increase friction support area.
(8) the vertical line that support bar free end the is corresponding vertical line corresponding with chair back free end overlaps or in outside, ensure that when lying appearance, the stability of seat center of gravity.

In figure: 1, seat board, 2, the chair back, 3, leg lean on, 4, chair leg, 5, support bar, the 6, first bar, the 7, the 2nd bar, 8, elasticity domatic, 9, hinged mechanism.
Embodiment
Being described in further detail by the utility model in conjunction with the accompanying drawings and embodiments now, these accompanying drawings are the schematic diagram of simplification, only with illustration, basic structure of the present utility model are described, therefore it only shows the formation relevant with the utility model.
As depicted in figs. 1 and 2, a kind of sitting posture is lain, and appearance is two uses student's seat, comprise: seat board, some the chair legs being fixedly installed on seat board bottom, and the chair back hinged with seat board edge, an at least hinged support bar on the chair back, also it is hinged with leg with the seat board edge of chair back opposite side to lean on, support bar has been installed as handrail in the basis of existing student's seat, realize the sitting posture of safety and comfort more, support bar rotates to chair back rear, can realizing the Gravity support to the chair back, one is dual-purpose, and what leg leaned on arranges and can support for the pose that leg provides more comfortable.
During seat maintenance sitting posture: support bar is positioned at above seat board as handrail; When seat keeps lying appearance: chair back layback certain angle, support bar forwards to below the chair back and is supported on ground.
When seat keeps lying appearance, the vertical line coincidence that the vertical line that support bar free end is corresponding is corresponding with chair back free end, or vertical line corresponding to support bar free end be positioned at the outside of vertical line corresponding to chair back free end. The vertical line that support bar free end the is corresponding vertical line corresponding with chair back free end overlaps or in outside, ensure that when lying appearance, the stability of seat center of gravity.
Hinged all realized by hinged mechanism. Between the chair back and seat board, seat board and leg lean between and hinged mechanism is installed between the chair back and support bar, it is achieved above-mentioned angular setting between any two and fixing.
