Description

Angle adjustment structure of seat armrest support pad

The invention relates to an angle adjustment structure for a seat armrest support pad, mainly referring to a stable structure capable of adjusting the angle of the armrest support pad.

Conventional seats are generally provided with armrests on both sides, and the forearms are supported by the armrests to improve riding comfort. Below the armrests, there are engaging posts that can be engaged with the seat body, and support pads in the front and rear directions are fixed above the engaging posts , And the support pad can provide forearm contact.

However, because the user's riding posture is different, and the angle of the forearm is different when the occupant is resting or typing or doing other work, the fixed-angle support pad cannot match the direction of the forearm to support the missing forearm.

In order to improve the applicability of the armrest, there is currently a support pad with adjustable angle. The bottom of the support pad is pivotally connected to the joint post, and the support pad can be pivoted to adjust the angle corresponding to the joint post. However, the pivotal force is often caused by the poor combination stability When large, the support pad cannot be stably set on the joint column and the support pad cannot be positioned stably.

The purpose of the present invention is to provide a structure with better stability that can adjust the angle of the support pad.

The invention includes an engaging post, a positioning block, and a supporting pad. The engaging post is engaged with the seat body under the engaging post, and the top has a lower engaging surface. The lower engaging mask has an accommodating groove, a pivot groove, and at least one limiting groove. The pivot groove has a joint hole in the center; the positioning block is made of elastic material and is arranged in the accommodating groove of the joint column; and an elastic piece portion capable of upward and downward flexible displacement movement is provided, and a convex portion is provided above the elastic piece portion A positioning body; and the supporting pad has a base, and an upper joint surface is provided under the base corresponding to the position of the joint surface under the joint post, and the upper joint surface is provided with a pivot post corresponding to the pivot groove position of the joint post, and a joint hole is provided in the center of the pivot post, It can be inserted into the combination of the support pad and the joint hole of the joint post by the joint element; and the positioning grooves on the upper joint surface corresponding to the position of the positioning body are arranged in plural at different angles and can be engaged with the positioning body; and the upper joint surface corresponds to the limit The position of the slot is set in the limit body which can act on the limit slot.

Further, the pivot groove of the engaging column is arranged behind the accommodating groove, and further includes an arc-shaped rear limit groove provided in front of the pivot groove, and an arc-shaped front limit groove provided in front of the accommodating groove; and the support The pad is placed in front of the pivot post of the upper joint surface to be able to limit the body after the action of the rear limit groove, and to the position of the limit groove in front of the upper joint surface corresponding to the front of the joint column, the limit body can be set before the displacement in the front limit groove, In addition, the front and rear limit bodies can respectively abut the side walls of the front and rear limit grooves to limit the maximum pivoting angle of the support pad.

Further, the support pad further includes an upper cover, a perforation through which the engagement element can be inserted at a position corresponding to the engagement hole above the base, and a plurality of insertion posts are provided above the base; a slot capable of engaging with the insertion posts is provided below the upper cover.

After the combination of the present invention, the joint column and the support pad are joined by a large area under the upper joint surface, which can have better combined stability, and the armrest is pivotally connected by the pivot column and the pivot groove, and the front and rear directions are The rear limit body is respectively engaged with the front and rear limit grooves, and the central position is joined by the positioning body and the positioning groove, which can be supported by an average force to have better combined stability, and the positioning block is made of a better flexible material, which can The positioning body and the positioning groove can have better positioning stability, and the side walls of the front and rear limit grooves can provide a stop for the front and rear limit bodies to ensure that the support pad does not rotate excessively during rotation. Excellent motion stability and service life.
