Multi-level adjustable and automatic return pedal folding mechanism for car seats

Abstract

The invention discloses a car seat pedal turnover mechanism capable of regulating in multiple stages and automatically returning. The car seat pedal turnover mechanism capable of regulating in multiple stages and automatically returning consists of a pedal returning mechanism and a multi-stage regulating and locking mechanism, wherein the pedal returning mechanism consists of a first return spring, a first pedal shaft, a first damping gear and a second damping gear; the multi-stage regulating and locking mechanism consists of a second pedal shaft, a locking wheel, a bracket, a left set bar, a left return spring, a left hinge pin, a right set bar, a right return spring, a right hinge pin, a driving block, a driving lever, a second return spring, a hinge pin and a pulling lever; when the foot of a passenger applies downward load to a pedal, the pedal rotates around the pedal shaft; the wedge-shaped locking groove of the locking wheel is meshed with the left set bar and the right set bar, and the pedal is locked; when the passenger does not use the pedal, the driving lever can be pressed to unlock the locking mechanism; meanwhile, an automatic returning mechanism begins to work; and the pedal automatically returns to the original nonuse position.

Description

technical field [0001] The invention relates to a pedal folding mechanism capable of multi-stage adjustment and automatic return of a car seat. technical background [0002] From the perspective of ergonomics, when the rear passengers are riding in the vehicle, in order to avoid the fatigue of the feet and legs due to being in one posture for a long time, it is especially important to set a pedal in front of the passengers to adjust the posture of the feet and legs. necessary. At present, there are two types of pedals equipped on vehicles: 1) fixed pedals, which are directly installed on the carpet. 2) The simple folding footboard is installed at the rear of the front seat. The characteristics of the fixed pedal are: the position is fixed, it is not easy to store, and it takes up the space of the car body carpet, while the characteristic of the simple folding pedal is: it can only realize simple folding, the use position is unique, and it cannot be used in different positi...

AI Technical Summary

Problems solved by technology

The characteristics of the fixed pedal are: the position is fixed, it is not easy to store, and it takes up the space of the car body carpet, while the characteristic of the simple folding pedal is: it can only realize simple folding, the use position is unique, and it cannot be used in different positions. lock up

On the one hand, it cannot meet the needs of passengers with different body proportions and does not conform to ergonomics. On the other hand, when not in use, it needs to rely on manpower to return it to the closed position. In snowy or rainy weather conditions, it is easy to Contamination of passenger's hands, poor ergonomics
