一种用于卡车座椅活动调节机构
By designing an adjustment component on the truck seat, the headrest height and angle can be quickly adjusted using the cooperation of hydraulic rods and positioning frames. This solves the problem of the headrest not being able to be adjusted quickly in the existing technology and improves the stability and service life of the adjustment component.

AI Technical Summary
Existing truck seat headrests cannot be quickly adjusted in angle or height, affecting their protective effect.
An adjustment assembly comprising a positioning shell, a hydraulic rod, a positioning block, a positioning frame, a mounting plate, and a Velcro hook surface is designed. Through the synchronous extension and retraction of the hydraulic rod and the cooperation of the positioning frame, the height and angle of the headrest can be quickly adjusted, and the Velcro hook surface facilitates the quick attachment and removal of the mounting shell.
It enables rapid and precise adjustment of headrest height and angle, enhances the stability and lifespan of the adjustment components, and improves driver comfort and safety.
