Roller armrest stepless adjustment mechanism and car seat armrest

Abstract

The invention discloses a roller type armrest stepless adjustment mechanism and an automobile seat armrest. An assembly cavity is arranged in the housing assembly, and a locking collision part and an unlocking collision part are arranged on the inner wall of the assembly cavity. A rotating shaft is installed for rotation, and a driving plate is fixedly sleeved on the rotating shaft. A roller fitting groove is provided on the outside of the driving plate, and a roller is arranged between the roller fitting groove and the inner wall of the assembly cavity. When the roller and the locking collision part occur After the collision, the two sides of the roller are respectively in contact with the groove bottom of the roller adaptation groove and the inner wall of the assembly cavity, and the drive plate is configured as a one-way motion structure relative to the housing assembly. When the roller collides with the unlocking collision part Afterwards, the roller is separated from the groove bottom of the roller fitting groove, and the driving plate can rotate freely within the stroke defined by the unlocking collision part and the locking collision part. The beneficial effect of the invention is that the structural design is ingenious, the product is easy to realize, the armrest is convenient to adjust, the armrest can be kept at any height position, and the comfort is good.

Description

technical field [0001] The invention relates to a vehicle armrest adjustment device, in particular to a roller type armrest stepless adjustment mechanism and an automobile seat armrest. Background technique [0002] With the upgrading of consumption level, people's pursuit of car comfort is getting higher and higher, such as the comfort requirements of seat armrests. [0003] The armrest is a functional accessory, which is usually arranged on the side of the seat, and is used to support the hands of the occupant, thereby improving the comfort of the occupant. In order to make the user's seating space flexible and changeable, some armrests are installed on the side of the seat in a foldable manner. In the prior art, these foldable armrests are mostly folded through simple rotating assembly. The height of the armrest cannot be adjusted, that is, the armrest has only two positions, the initial point and the end point of use, so that the armrest cannot meet the needs of users o...

AI Technical Summary

Problems solved by technology

In order to make the user's seating space flexible and changeable, some armrests are installed on the side of the seat in a foldable manner. In the prior art, these foldable armrests are mostly folded through simple rotating assembly. The height of the armrest cannot be adjusted, that is, the armrest has only two positions: the initial point and the end point of use, which makes the armrest unable to meet the needs of users of different sizes, and the comfort needs to be further improved

[0004] Even though a small number of handrails use stepless adjustment mechanisms to adjust the height of the handrails, these existing stepless adjustment mechanisms still have technical defects such as overly complex structures, high manufacturing costs, and easy damage.
