In the scheme, the method comprises the following steps: the clamping grooves on each supporting leg are uniformly arranged at intervals. Each clamping groove corresponds to one height adjusting gear, the interval between every two adjacent gears is even, the distance adjusted every time is easier to control, and the adjustment is more convenient.
In the scheme, the method comprises the following steps: the lower end face of the headrest foam is matched with the outer contour of the upper end face of the backrest. It is advantageous to reduce the minimum adjustment height of the headrest as much as possible.
The utility model has the beneficial effects that:
1. because two feet of the headrest rod extend in an arc shape with the extending direction facing forwards, when the height of the headrest foam is adjusted through the headrest rod, the headrest foam can also do inclined motion along with the up-and-down movement of the headrest rod, the headrest foam tilts forwards when the headrest rod moves upwards, and the headrest foam reverses when the headrest rod moves downwards, namely, the headrest can not only realize simple up-and-down adjustment, but also has a certain front-and-back adjusting function, can better support the head of a passenger, improve the comfort level of the passenger, and strengthen the protection effect of the head.
2. The guide bush is arranged in the through hole, and can reduce noise generated when the headrest rod moves, can play a role in guiding the headrest rod, and improves stability of the headrest rod during adjustment.
3. The headrest rod is locked by the clamping block on the pressing piece and the clamping groove on the headrest rod forming a clamping structure, the structure is simple, and the headrest height can be quickly adjusted manually.
4. Be provided with a plurality of draw-in grooves on the stabilizer blade, can realize the many grades of regulations of headrest height, application range is wide, can satisfy different passenger's demand.
