Description

Convenience headrests for cars, trains and airplane seats {omitted}

Conventional headrests do not provide a comfortable and comfortable environment for passengers taking a rest or sleep during driving and drivers taking a rest after parking because the headrest of the passenger's head is one flat structure. Overcoming the situation

By dividing the existing headrest part into two upper and left two and one lower side, the upper two cushions flow from side to side according to the button operation of the rider and utilized as a head support, and the lower cushion is also tilted back and forth with an oblique downward slope according to the button operation. It protrudes and sinks to be used as a neck support. The upper cushion movement method is equipped with a guard rail horizontally inside the headrest supporter, and then moves left and right by the motor and the driving wheel on the rail, and the lower cushion movement method is provided along the guardrail installed in the front and rear directions on both sides of the headrest supporter. It flows back and forth to serve as head support and neck support respectively. The seat back can be widely adjusted in the above state only when the backrest is flipped over a certain angle, and within a certain angle, the seat back is limited to the operating limit and thus cannot be operated extensively. The reason for not giving excessive neck support protrusion and wide head support depression by giving operating limits is to prevent the injured neck of the occupant in case of sudden forward and backward accident in the posture close to the vertical. When the parking brake is applied, it is within the wide operating range without the above limit regardless of the angle of the seat back.

When both sides of the upper and lower cushion pads are widened to the maximum width, there is a lot of free space for the passenger's head to be flipped, and the neck support cushion on the lower side protrudes a lot, so that the neck can be flipped. Safety measures are to be provided to prevent neck injury.

When the seat back angle is within a certain angle, the distance between the two cushion pads 20 of the head support is limited to a certain degree, and the limit device 33 that the cushion of the neck support 30 does not protrude more than a certain degree is seated in case of sudden front and rear collision. Prevents neck injuries Seating seats limit the seat 33, regardless of the angle of the seat back when the seat is in the parking state even when the seat load and engine start, and the circuit is configured to be released only when the seat back is flipped over a certain angle.

The passenger can take a rest and sleep comfortably while supporting the head and neck on the cushion pad without shaking the left and right heads caused by driving vibration and road vibration, which can remove the stiffness of the neck and shoulders. When you relax, you can get rid of a lot of fatigue in a short time and avoid the stress of flat back pressing. When the system is applied to public operations such as express buses, trains and airplanes, the comfort of the seat structure prevents the seat backing to some extent, providing the passengers with a wider boarding space and providing additional cushions. In the case of class seats, the company's image enhancement effect is great due to the comfort of seat improvement without providing cushion.

The present invention relates to a head restraint of a comfortable and comfortable car, train, and airplane, by dividing the existing headrest portion into a total of three, the upper left and right two (20) and the lower one (30), the upper two cushion pads (20) ) And left and right cushion pad (30) is a convenience type headrest that provides more comfort and practicality to the seat by supporting the head and neck of the seat by flowing in the front and rear front projection of the oblique inclination. A guard having a slight inclination in the front and rear directions on both sides of the lower side of the headrest support board 10 is built in the horizontal guard rail 21 for flowing two upper cushion pads 20 inside the headrest support board 10. By installing the rail 31, the lower neck cushion pad 30 is utilized as a floating rail protruding. The horizontal rail 21 is embedded inside the headrest support board in fear of friction with the rear part where the occupant's head touches, and the support of the lower neck support cushion 30 is a c-shape 31 inside the headrest support board 10. When they meet each other, they move to balance the left and right together when protruding and sinking. Each of the cushions 20 and 30 moves on the guard rail 21 by the motor 25 and the driving wheel, and the sensor contacts are mounted on the guard rail to move only within a certain range. The maximum width of the upper head support and the maximum protrusion of the lower neck support are allowed only when the seat back is flipped over a certain angle, and the operating limit 33 is limited within a certain angle and thus cannot be operated extensively. The reason for not giving excessive head support width and excessive neck protruding point by operating limit point is to prevent neck injury in case of sudden forward and backward accident in posture close to vertical. However, when the parking brake is applied, that is, when the car is in the main or sperm, the limit 33 is released regardless of the angle of the seat back, so that the passenger can freely adjust the headrest, and the train and the plane operate without considering the above conditions. The operation is by buttons 41 and 42 installed on the seat side.
