Detailed description of the invention
A kind of chair headrest fold mechanism, its structure is: described chair headrest fold mechanism is made up of carriage 1, kinematic link 2, shift knob bar 3, head rest pole 4, ratchet device 5, connecting rod torsion spring 6, ratchet torsion spring 7 and folding torsion spring 8;
Described carriage 1 is the U-shaped structure of lower ending opening; The two ends of one turning cylinder 4-1 are connected with the upper end of two head rest poles 4 respectively, and carriage 1 lower end is socketed on turning cylinder 4-1, and head rest pole 4 is positioned at outside carriage 1, and the lower end of head rest pole 4 is connected with the chair back; Shift knob bar 3 is arranged in the horizontal side wall of carriage 1, and the outer end of shift knob bar 3 is positioned at outside carriage 1, and the inner of shift knob bar 3 is positioned at carriage 1; Be provided with pin 1-1 in carriage 1, pin 1-1 is axially parallel with turning cylinder 4-1, and pin 1-1 is positioned on the downside of shift knob bar 3, and that end near shift knob bar 3 on pin 1-1 protrudes from carriage 1 outer wall; Ratchet device 5 is socketed on pin 1-1, and ratchet device 5 is positioned at the top of head rest pole 4 outside carriage 1, and ratchet device 5 and pin 1-1 are rotationally connected, and head rest pole 4 upper surface are provided with the draw-in groove mated with the latch on ratchet device 5; Ratchet torsion spring 7 is arranged on ratchet device 5, and ratchet torsion spring 7 can apply torsion to ratchet device 5 and make the latch on ratchet device 5 be close in draw-in groove; Described ratchet device 5 arranges driving lever 5-1, and driving lever 5-1 is axially parallel with turning cylinder 4-1, and position corresponding with driving lever 5-1 on carriage 1 is provided with through hole, and driving lever 5-1 the inner extends in carriage 1 through after through hole; Described kinematic link 2 is arranged in carriage 1, and kinematic link 2 top and shift knob bar 3 the inner are in transmission connection, and closing button spindle 3 can slightly swing by transmission kinematic link 2; Be provided with extension in the middle part of described kinematic link 2, extension extends to below driving lever 5-1, and when kinematic link 2 swings, extension can by driving lever 5-1 upwards jack-up; Connecting rod torsion spring 6 one end is fixed, and connecting rod torsion spring 6 other end is connected with kinematic link 2, and connecting rod torsion spring 6 can apply predetermincd tension to kinematic link 2, makes kinematic link 2 be in reset mode all the time under the state of not stressing; Folding torsion spring 8 is socketed on turning cylinder 4-1, and folding torsion spring 8 one end is connected with head rest pole 4, and folding torsion spring 8 other end is connected with pin 1-1, and after the latch on ratchet device 5 is deviate from draw-in groove, folding torsion spring 8 can drive carriage 1 to overturn.
