Abstract

The invention relates to an automobile seat headrest adjusting mechanism used for up-down and front-back electrical control. The automobile seat headrest adjusting mechanism comprises a headrest height electric adjusting mechanism and a headrest front-back translation electric adjusting mechanism, wherein a headrest rod of the headrest front-back translation electric adjusting mechanism is fixed on a headrest rod support of the headrest height electric adjusting mechanism by virtue of two Omega-shaped springs. The automobile seat headrest adjusting mechanism disclosed by the invention has the advantages that structure is novel, the headrest height electric adjusting mechanism and the headrest front-back electric adjusting mechanism are integrated, a four-directional adjusting mechanism is systematacially integrated, and comfort is provided for passengers to the utmost extent. Front-back translation distance of a headrest can reach up to 60mm, compared with the traditional headrest without front-back adjustment and the headrest which adjusts a front-back position by utilizing rotation, translation for 60mm can meet comfort requirement of people in different percentiles and the people with different head styles to the utmost extent.

Description

technical field [0001] The invention relates to an automobile seat headrest adjustment mechanism capable of electrically adjusting the height up and down, and electrically adjusting the level forward and backward. Background technique [0002] With the vigorous development of the automobile industry, people have put forward higher requirements for the comfort of automobile seats. As a special product in car seats, car seat headrests are required to have high comfort in addition to the safety function of protecting the human head. People with different heights put forward adjustable requirements for the height position of the car seat headrest. For example, the 5th percentile of women requires that the seat headrest can be lowered to adapt to their sitting posture; different people have different requirements for the car seat headrest. The front and rear positions also put forward adjustable requirements, for example, women with braids request that the headrest can be adjust...
