Description

A kind of attachment means of headrest and seat body

Technical field

The present invention relates to the attachment means of seating art field, more particularly to a kind of headrest and seat body.

Background technology

Seat is that people's work, study are got along one of time most long instrument, is claimed in the aesthetic measure to seat Before, it is often more important that ensure that seat can have good level of comfort, the seat for possessing headrest can more protect the cervical region of people, subtract After slow sitting, cervical region produces fatigue, increases the onset risk of cervical spondylosiss, but the headrest of common seat is fixed in the market , it is impossible to the people for adapting to different heights required to the difference of height of headrest, and the seat for having active head restraint when using not yet It is convenient.

The patent of 201911660 U of Publication No. CN is authorized to disclose a kind of adjusting means of chair headrest, including head Pillow, support column, the fixed seat for being fixed on backrest top, offer chute in the fixed seat, support column can be upper and lower It is slidably mounted in the chute of fixed seat, support column is provided with the lifting regulating mechanism for adjusting height of headrest with fixed seat, leads to The positioning that a bayonet lock is crossed with the engaging realization headrest of the location hole for arranging on the support columns, when needing to adjust the height of headrest, Need on the other hand bayonet lock to be detached and kept, another handss will be rested the head on and pull-up or be pressed, and practical operation is simultaneously inconvenient, and does not slightly note Meaning, headrest easily exceed adjustable extent and are directly extracted, very experience lf being influenced.

The patent of mandate 203597652 U of Publication No. CN discloses a kind of multidirectional active head restraint structure of chair, has The headrest of slide block is slided to realize that headrest is slided up and down in hoistway, and by wavy on the slide block that cooperates Multistage restriction protrusion realizes the multistage positioning slided with the arc shaped contact on wiper, and by the cooperation of stopper slot and limited block The adjustable extent of headrest is limited, headrest will not be completely pulled out of when height of headrest is adjusted.But the complex structure, headrest Installation and taking out need through installing or removing wiper realizing, process is loaded down with trivial details, it is impossible to realize the Fast Installation of headrest with Remove.

The content of the invention

It is an object of the invention to provide a kind of headrest and the attachment means of seat body, can overcome the deficiencies in the prior art Part, when realizing that convenient and strength-saving ground one hand ensures normal use while carrying out the regulation of height of headrest, headrest will not drop out seat Body, and the Fast Installation for realizing being rested the head on convenient and strength-savingly and dismounting.

The present invention above-mentioned technical purpose technical scheme is that：

A kind of headrest and the attachment means of seat body, including the body coupling assembly being connected with seat body, are inserted in institute State between body coupling assembly and seat body can height up and down head rest attachment, located at the body coupling assembly The control assembly that the interior control head rest attachment moves up and down.

Preferably, the body coupling assembly include matrix, longitudinal direction be opened on the matrix for the head Pillow connector carry out spacing cavity, be opened on the opposite face of the cavity setting face for accommodating the control assembly Cavity, the cover plate with the annular groove control assembly being limited in the cavity.
