Specific embodiment
The specific structure in the utility model is done to illustrate with reference to the accompanying drawings of the specification:
A kind of headrest electric adjusting mechanism for angle, as depicted in figs. 1 and 2 comprising back rest 1, be hingedly mounted on it is described
Pillow 2, the Vidacare corp for driving 2 swing of pillow at 1 top of back rest, the pillow 2 wrap
Two are included to pass through two head rest attachments 4 hinged with the side frames 11 of the back rest 1 of pin shaft 3 respectively and connect two headrest connections
The transverse link 5 of part 4,11 bottom end of side frames are fixedly connected by connecting cross beam 6, have arc on each head rest attachment 4
Limit hole 41, the side frame 11 are equipped with the spacer pin 12 that matches with the arc-shaped limit hole 41, the pillow 2 around its with
The spacer pin 12 moves in the arc-shaped limit hole 41 when rotation before and after the hinged place of back rest 1, and the pillow 2 is distinguished
When in maximum angle position and minimum angles position, the spacer pin 12 both ends end face with the arc-shaped limit hole 41 respectively
It offsets.Structure using the headrest electric adjusting mechanism for angle in the present embodiment is simple, constituent parts negligible amounts, assembly side
Just, when this headrest electric adjusting mechanism for angle is installed and used, Vidacare corp drives pillow 2 to rotate forward around pin shaft 3
The purpose for adjusting pillow 2 forward can be realized, drive pillow 2 to rotate backward around pin shaft 3 by Vidacare corp
Realize the purpose for adjusting pillow 2 backward.
In the present embodiment, the Vidacare corp includes push-rod electric machine 7 and reset tension spring 8, is consolidated on the transverse link 5
