Description of drawings:
Fig. 1 is the side view of the sliding seat of the utility model preferred embodiment when being in appearance, and controlled air spring piston rod is in the state that stretches out fully;
Fig. 2 is the side view of the sliding seat of the utility model preferred embodiment when being in lying posture, and controlled air spring piston rod is in complete contraction state.
The specific embodiment:
Referring to Fig. 1, Fig. 2, the utility model embodiment is provided with preceding mounting bracket 1, front wheel driving bar 2, controlled air spring 3, rear drive bar 4, back bracket 5, back mounting bracket 6 and control assembly 9, preceding mounting bracket 1 connects front wheel driving bar 2 by bolt and is fixed on the front portion of handrail yoke 8, can make the sofa of different in width by the adjusting of front wheel driving bar 2, rear drive bar 4 length.The front end of controlled air spring 3 links together with front wheel driving bar 2 by the first rotating shaft A (pin), and the rear end of controlled air spring 3 links together with rear drive bar 4 by the second rotating shaft B (pin).Front wheel driving bar 2, rear drive bar 4 are the equal length pipe fitting.The both sides of rear drive bar 4 are fixed together by the bottom of bolt and back bracket 5, and control assembly 9 is connected with controlled air spring 3.Back mounting bracket 6 is fixed on the handrail yoke 8.Backrest yoke 7 is connected with the top of back bracket 5 by the KD connector, also can easily pull down when needs are pulled down transportation, for the transportation of finished product sofa is provided convenience.
The user is in opening by controlling control assembly 9 (present embodiment adopts the meta drag-line) with controlled air spring 3, back pressure backrest yoke 7 simultaneously, backrest yoke 7 clockwise rotates along the 3rd rotating shaft C, and controlled air spring 3 is owing to pressurized under opening, so piston rod is compressed.The user only need unclamp the meta drag-line at an arbitrary position, and controlled air spring 3 promptly is lockable, thereby has guaranteed the conversion of sofa backrest angle.
When the piston rod stroke all was compressed, the angle maximum of backrest inclination reached state shown in Figure 2 this moment.Owing to bear bigger weight on the backrest yoke 7 at this moment, so design and used the spacing realization that guarantees its function in two places, promptly spacing 11 (the spacing rivets) in use back are next spacing next spacing with use front limit 10 (limited block).
The simple deformation of technical solutions of the utility model or technical characterictic, for example different control assemblies such as built-in handle type, switching mode etc., and the equivalents of connected mode all belongs to the novel scope that needs protection of this use.
