Automobile seat mechanical leg support mechanism with adjustable gears

Abstract

The invention relates to an automobile seat mechanical leg support mechanism with adjustable gears. The automatic seat mechanical leg support mechanism with the adjustable gears comprises two sets of adjusting mechanisms, a leg support skeleton and two sets of four connecting rod mechanisms, wherein the two sets of adjusting mechanisms and the two sets of four connecting rod mechanisms are arranged in a left and right mirror mode relative to a seat central plane; each adjusting mechanism comprises a mounting plate, a ratchet wheel, a detent, a limiting pin and an unlocking slide sheet are arranged on each mounting plate, wherein the ratchet wheels are rotatably connected with the mounting plates through rotary shafts, the detents are engaged with the ratchet wheels to achieve locking, and the limiting pins and the unlocking slide sheets are matched with the ratchet wheels to achieve unlocking; the two power input ends of the each four connecting rod mechanism are fixedly connected with the corresponding ratchet wheel and the detent correspondingly, and the power output ends of the four connecting rod mechanisms are fixedly connected with the leg support skeleton; and a return mechanism matched with the corresponding ratchet wheel and the detent to achieve returning of the corresponding four connecting rod mechanism is further arranged on each mounting plate. The automobile seat mechanical leg support mechanism with the adjustable gears simplifies the complex structure of a leg support system, improves the comfort of a seat, provides great convenience for subsequent maintenance of the seat, saves additional adding of buttons through utilization of a self-unlocking structure, and reduces the cost.

Description

The car seat leg support system has been gradually popularized and used in commercial vehicles in recent years. It can provide a certain amount of support for the lower legs, relieve the discomfort of the legs when sitting for a long time, and is of great help to improve the comfort of the seat, but the long-term Since the past, most of the seat leg support systems have adopted gas spring structure, lead screw structure, and worm structure. Not only the cost is too high, the structure is complicated, and the quality problem is difficult to guarantee, but additional buttons are required, which increases the cost and increases the overall cost. chair weight
