Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology, specifically relating to an actively supportive pneumatic side wing sleep headrest and its application in automobiles. Background Technology

[0002] Chinese patent CN 212979989 U discloses a pneumatic sleep headrest airbag inflation and deflation adjustment mechanism. This mechanism uses an airbag adjustment method to adjust the height of the headrest side wings to different levels, providing lateral support to suit various needs and offering better protection for occupants during rest. However, the left and right airbag adjustment assemblies are assembled together with a locking seat and a support plate via a slot. Air from the air pump is transmitted to these assemblies through an air pipe, and the height of the headrest side wings is adjusted based on the internal air content. While this structure effectively controls the airbag adjustment assemblies during inflation, it suffers from inconvenience and slow adjustment speed when deflation is needed to lower the headrest side wings. Summary of the Invention

[0003] In view of the above-mentioned technical problems and shortcomings, the purpose of this utility model is to provide an actively supportable pneumatic side-wing sleep headrest. This headrest provides a thrust for forward folding movement by inflating a fan-shaped air bag; the air bag provides side wing support at different angles while maintaining its state; the side wings are installed by folding, and a torsion spring is provided at the side wing pivot point with a preload direction of retraction, so that the side wings can automatically retract backward when the air bag is deflated, which is convenient for adjustment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A pneumatically winged sleep headrest with active support includes a headrest body, a left supporting wing, a right supporting wing, a left fan-shaped air bag, a right fan-shaped air bag, and an air pump. The headrest body has an assembly section in the middle, and assembly bushings on both sides of the assembly section. Side wing pivots are mounted on the assembly bushings. The left and right supporting wings are connected to the side wing pivots and fold relative to the headrest body along the pivots. A torsion spring is mounted on the side wing pivots to provide a preload force for the left and right supporting wings to retract backward. The left fan-shaped air bag is positioned between the left supporting wing and the headrest body, and the right fan-shaped air bag is positioned between the right supporting wing and the headrest body. The air inlets of the left and right fan-shaped air bags are connected to the air pump via air pipes.

[0006] As a preferred embodiment of the present invention, the headrest further includes a controller, which is used to control the movement of the left and right fan-shaped air bags individually or simultaneously.

[0007] As a preferred embodiment of the present invention, the headrest body includes a front cover and a rear shell. The front cover is provided with an assembly part and a through hole is provided on the front cover at a position opposite to the air inlet connectors of the left and right fan-shaped air bags. The interior of the rear shell is a hollow structure. The air inlet connectors of the left and right fan-shaped air bags pass through the through hole of the front cover and are disposed inside the headrest body.

[0008] As a preferred embodiment of this invention, the left and right fan-shaped air bags are controlled by an air pump and a controller, enabling them to be inflated, maintained, and deflated.

[0009] As a preferred embodiment of this utility model, the controller and air pump are mounted and fixed on the seat back frame, and the air pipe passes through the hollow cavity of the headrest rod and is connected to the air inlet connectors of the left and right fan-shaped air bags.

[0010] This utility model also provides a car, wherein the backrest frame of the car seat is equipped with the aforementioned actively supportive pneumatic side wing sleep headrest. The car is equipped with a speed sensor, an acceleration sensor, and an angle sensor. The speed sensor is used to monitor the current vehicle speed, the acceleration sensor is used to monitor lateral acceleration, and the angle sensor is used to monitor the steering wheel angle. The data monitored by the speed sensor, acceleration sensor, and angle sensor are sent to the controller of the pneumatic side wing sleep headrest. The controller controls the left or right support wing to move forward and actively provide lateral support for the head based on the vehicle speed, lateral acceleration, and steering wheel angle signals.

[0011] Advantages and beneficial effects of this utility model:

[0012] (1) The side wings of the pneumatic side wing sleep headrest provided by this utility model can be folded. A torsion spring is provided at the pivot of the side wing. The preload direction is to retract backward, so that the side wings can automatically retract backward when the air bag is deflated, which is convenient for adjustment and provides a better user experience.

[0013] (2) The left and right support wings of the pneumatic side wing sleep headrest provided by this utility model can move simultaneously to provide a sleep function; they can also provide active support function through single-sided control when cornering at high speed, reducing neck pressure. This headrest is applicable to a wider range of scenarios.

[0014] (3) The air inlet connector on the pneumatic side wing sleep headrest provided by this utility model is located inside the headrest body, and the air pipe is located inside the headrest rod. With this structure, the decibel value received by the head is lower when pneumatically inflated. Attached Figure Description

Side wing pivots 8 are installed on the assembly bushings 102. The left supporting side wing 2 and the right supporting side wing 3 are connected to the side wing pivots 8 and fold relative to the headrest body 1 along the side wing pivots 8. A torsion spring 9 is provided on the side wing pivot 8. The torsion spring 9 is used to provide a preload force for the left support side wing 2 and the right support side wing 3 to retract backward. The left fan-shaped air bag 4 is disposed between the left support side wing 2 and the headrest body 1, and the right fan-shaped air bag 5 is disposed between the right support side wing 3 and the headrest body 1.
