A pair of of vertical beam, the front carriage and the outside front ends of the curb girder of seat frame are hinged, and the front end of the vertical beam is equipped with oblique angle card
Connector, the oblique angle clamping joint are equipped with the first blocked hole and the second blocked hole, and the upper end of the posterior bracket is solid equipped with oblique angle
Determine head, the fixing groove for being inserted into oblique angle clamping joint is offered in the oblique angle fixing head, the two sides of the fixing groove open up
There are upper fixation hole and lower fixed hole, the first blocked hole of the oblique angle clamping joint and the upper fixation hole of oblique angle fixing head pass through pin shaft
It is hinged with side rail inner, it is equipped with L shape link block between the vertical beam and posterior bracket, the both ends of the L shape link block are equipped with the
One connecting hole and the second connecting hole, the two sides of the oblique angle clamping joint are equipped with sliding shoe, and the both ends of the sliding shoe are equipped with the
One through-hole and the second through-hole, the first through hole are connect with the first connecting hole by pin shaft, the second through-hole and oblique angle clamping joint
Second blocked hole is connected by pin shaft, and the lower fixed hole of second connecting hole and oblique angle fixing head passes through pin shaft and side rail inner
Hingedly, the oblique angle between the posterior bracket and oblique angle fixing head is 120 ° to 150 °, between the vertical beam and oblique angle clamping joint
Oblique angle be 120 ° to 150 °, be equipped with two arm-rest frames above two curb girders of the seat frame, one end of two arm-rest frame with
The outside of vertical beam is hinged, and the outside of the other end and front carriage is hinged.
Preferably, the posterior bracket is structure as a whole with oblique angle fixing head.
Preferably, the vertical beam is structure as a whole with oblique angle clamping joint.
By using above-mentioned technical solution, the beneficial effects of the present invention are: the present invention can reduce folded product body
Product, and mitigate the weight of product, it is very low to appearance limitation, it is able to achieve the diversification of shape.
