Car seat armrest mechanism capable of freely shifting gears

Abstract

A car seat armrest mechanism capable of freely shifting gears comprises an articulated shaft sleeve installation support and an articulated shaft. An articulated shaft sleeve is installed on the articulated shaft sleeve installation support, and an armrest installation plate is connected with the articulated shaft sleeve and can rotate around the articulated shaft sleeve; and a fixed pawl and a locking piece are installed on the articulated shaft sleeve, and a swing pawl is installed on a fixed shaft and provided with at least four swing pawl clamping grooves matched with fixed pawl clamping teeth on the fixed pawl, so that an armrest is provided with the at least three use gears and can circularly rotate between the lowest gear and the gear-up position. The car seat armrest mechanism capable of freely shifting the gears has the advantages that the structure is simple, operation is convenient, and the safety is better; the structure of an armrest installation support is changed, and the car seat armrest mechanism can be matched with most of seats in the market; through the multiple use gears and gear-up-and-down free adjusting, the armrest can be unlocked at any gear by unlocking buttons, and any gear can be freely shifted; and through the engaged structure of the fixed pawl and the swing pawl, the working stability and reliability are higher.

Description

Technical field [0001] The invention relates to the field of automobile parts, in particular to a freely shiftable automobile seat armrest mechanism. Background technique [0002] The car seat is one of the essential components of a car, and it is also an important component to provide passengers with driving support and safety protection. Seats are a relatively large purchase part in vehicle manufacturing and are of higher importance; seat armrests are an important component to improve the comfort of car seats. The armrest of the seat can generally provide several supporting positions to facilitate the support and relaxation of the passenger's arm. A good armrest design can improve the comfort evaluation of the entire chair. In addition, the structure of the armrest of the car seat will directly affect the safety effect of the entire car seat. [0003] However, there is still a lot of room for improvement in the armrests of car seats on the market. For example, the adjustment me...

Problems solved by technology

In addition, the structure of the car seat armrest will also directly affect the safety effect of the entire car seat.

[0003] However, there is still a lot of room for improvement in the armrests of car seats on the market. For example, the adjustment mechanism is complex and the gear switching is not smooth; Problem; the support gears cannot be switched at will, and the degree of freedom is low
