Abstract

The invention relates to a six-direction electric adjusting mechanism for a car seat headrest. The six-direction electric adjusting mechanism comprises a headrest height electric adjusting mechanism, a headrest frontward and rearward translation electric adjusting mechanism and a headrest two-wing angle manual adjusting mechanism, wherein a headrest rod of the headrest frontward and rearward translation electric adjusting mechanism is fixed to a headrest rod bracket of the headrest height electric adjusting mechanism through two Omega-shaped springs; and a headrest two-wing bracket of the headrest two-wing angle manual adjusting mechanism is fixed with a headrest front bracket of the headrest frontward and rearward translation electric adjusting mechanism in a clamped way. The six-direction electric adjusting mechanism has the advantages as follows: the structure is novel, the headrest height electric adjusting mechanism, the headrest frontward and rearward translation electric adjusting mechanism and the headrest two-wing angle manual adjusting mechanism are integrated, a six-direction adjusting mechanism is integrated in a system, the highest possible comfort is provided for a passenger, the comfort requirements of the people with different heights and different head styles can be met to a maximum extent, and the supporting requirement of the headrest on the head of the passenger having a rest can be met by two-wing adjustment.

Description

technical field [0001] The invention relates to an automobile seat headrest adjustment mechanism capable of electrically adjusting the height up and down, electrically adjusting the level front and rear, and manually adjusting the front and rear angles of two wings. 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, wome...
