Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle seats, relates to a seat headrest, and particularly relates to a novel two-way adjustable headrest. Background Art

[0002] A headrest assembly is usually arranged on an existing vehicle seat, and a button is arranged on the headrest assembly. The height of the headrest is adjusted by pressing the button on the headrest assembly. However, most common adjustable headrests adopt single-sided locking. If the single-sided locking function fails, many adverse consequences will occur. In addition, the headrest rod of the existing headrest assembly is usually a U-shaped headrest rod. When adjusting up and down, the moving space avoided by the middle headrest shell is large, resulting in an insufficiently compact overall structure and relatively weak strength of the headrest shell. Summary of the Invention

[0003] In view of the above technical problems and disadvantages, the purpose of the utility model is to provide a novel two-way adjustable headrest. The headrest adopts two independent headrest rods. When adjusting up and down, the middle headrest shell does not need to reserve a moving space, and only needs to avoid the moving space of the left and right headrest rods. This not only makes the overall structure of the headrest simpler, the installation more compact, and the cost lower, but also can increase the strength of the headrest shell.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A novel two-way adjustable headrest includes a headrest shell, a button body, a cross bar, a cross bar return spring, two guide sleeves, two independent headrest rods, two fixing pins, and two locking pins; wherein, the button body is arranged on one side of the headrest shell and is used to drive the cross bar to move horizontally; the cross bar is arranged in the headrest shell, and the end is in contact with the button body. It can move horizontally relative to the headrest shell, and a cross bar return spring is arranged between the cross bar and the headrest shell; the cross bar return spring is used to push the cross bar to return; both of the two guide sleeves are clamped into the headrest shell. A hanging portion is arranged on the outer side wall of the guide sleeve, and a limiting groove is arranged on the guide sleeve; the two headrest rods are respectively assembled into the two guide sleeves, and mounting holes are arranged on the headrest rods at positions opposite to the limiting grooves on the guide sleeves; the two fixing pins are respectively fixed in the mounting holes of the two headrest rods, and both ends extend beyond the headrest rods and extend into the limiting grooves of the guide sleeves to limit the rotation of the headrest rods through the fixing pins; one end of the locking pin is fixed on the hanging portion of the guide sleeve, and the other end passes through the guide sleeve and is arranged in the assembly hole of the cross bar, and the locking pin is driven by the cross bar to move away from the locking groove of the headrest rod.

[0006] Preferably, the headrest further includes a foam, a comfort sponge, and a skin; wherein, the foam is arranged on the headrest shell, the comfort sponge is arranged on the foam, and the skin is used to wrap the comfort sponge and the foam.

[0007] As a preference of the present utility model, the button body includes a button, a button cover, and a button return spring; wherein, the button cover is snap-connected to the headrest shell, the button is arranged inside the button cover and can move horizontally relative to the button cover, and the button return spring is arranged between the button and the button cover for pushing the button to return to its original position.

[0008] As a preference of the present utility model, a through opening is provided on the guide sleeve near the hanging portion, and the locking rod of the locking pin passes through the through opening and the inside of the guide sleeve and extends into the assembly hole of the cross bar; an avoidance notch is provided on the guide sleeve near the through opening.

[0009] As a preference of the present utility model, three locking grooves are provided on each headrest rod, and the distance between two adjacent locking grooves is controlled at 17.5 mm.

[0010] Advantages and beneficial effects of the present utility model:

[0011] (1) The headrest provided by the present utility model only needs two independent headrest rods. When adjusting up and down, there is no need to reserve movement space for the middle headrest shell, and only the movement space of the left and right headrest rods needs to be avoided. This not only makes the overall structure of the headrest simpler, the installation more compact, and the cost lower, but also can increase the strength of the headrest shell; in addition, the headrest is locked in two directions and is more firmly fixed.

[0012] (2) The guide sleeve adopted by the headrest provided by the present utility model has a large Z-direction dimension, which can effectively prevent the headrest rod from shaking and generating noise, making the overall structure more stable.

[0013] (3) The headrest provided by the present utility model can realize the up and down adjustment of the headrest, so that when people of different heights are sitting, by adjusting the height of the headrest, their heads can be directly opposite the headrest, and the head and neck parts of the driver and passengers can be better protected in the event of a rear-end collision of the vehicle.
