Description

Technical Field

[0001] The invention relates to the technical field of a middle headrest in the rear row of an automobile, and in particular to a middle headrest assembly in the rear row of an automobile. Background Art

[0002] The car headrest is a driving comfort configuration and safety protection product. When a vehicle rear-ends, the human body will fall backwards due to inertia. At this time, the pressure of the vehicle's acceleration or deceleration is concentrated on the human body's fragile neck and head, and the headrest plays a buffering role to protect the human head.

[0003] At present, the traditional rear seat headrest design of automobiles generally has the following two situations:

[0004] The first type is that there are headrests on both sides of the rear seats of the car, but no headrest in the middle. Although this design can increase the overall beauty of the car, when there are three people sitting in the back seat of the car, the person sitting in the middle can only sit upright or lean forward, and cannot lean on the cushion to prevent injuries to the neck due to lack of support for the head due to sudden braking of the car or other situations. If the person sits for a long time, the body will easily become stiff and cause body pain, which reduces the person's experience and increases the person's fatigue.

[0005] The second type is that although there are three headrests in the rear seat of the car, the middle headrest is smaller. When the person's head rests on the headrest, the upper part of the head is exposed outside the headrest. At this time, if the car is bumpy or other situations occur during driving, it is easy for the person's head to collide with the upper part of the headrest multiple times, which can easily cause injury to the person and reduce the person's comfort.

After positioning, the first blocking pad 751, the first protection pad 74 and the first blocking pad 751 in the second blocking pad assembly 76 form a V-shape to intercept the person's head, prevent the person's head from swinging left and right, and increase the comfort of the person.

[0047] Embodiment 3

[0048] like Figure 1-Figure 9 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0049] In order to rotate the auxiliary pillow assembly 7 from a horizontal state to a vertical state, thereby increasing the area of ​​the first plate 6, so that when the head of a person rests on the pillow mechanism, the headrest mechanism feels large in area, giving the person a comfortable feeling, this embodiment will provide the following technical solutions:

[0050] The flip assembly 8 includes a first bracket 81, one side of the first plate 6 is fixedly connected with the first bracket 81, both ends of the first bracket 81 are respectively fixedly connected with an arc frame 82, one end of the arc frame 82 is fixedly connected to one side of the first plate 6, both ends of the angle shaft 94 are respectively fixedly connected with the arc frame 82, one side of the arc frame 82 is installed with an angle component 83, and the top surface of the first bracket 81 is installed with an unlocking component 84.

[0051] By pulling the pulling rod 847, the pulling rod 847 will drive the U-shaped unlocking frame 848 to move. When the U-shaped unlocking frame 848 moves, one end of the column rod 844 will be disengaged from the socket 833 under the action of the inclined block 845. After disengagement, the auxiliary pillow assembly 7 can be rotated to rotate along the first plate 6, thereby increasing the area of ​​the overall headrest, allowing the person's head to rest on the pillow, avoiding the upper part of the head being exposed, causing the person to feel uncomfortable when resting his head on the headrest.

[0052] The working principle and use process of the present invention:

[0053] In use:

[0054] When using:

[0055] To adjust the height of the headrest mechanism 2, first, pull the reset block 34 so that the reset block 34 drives the card plate 35 to move, and at the same time, the reset damping rod 33 is stretched. When the card plate 35 moves, the card plate 35 will be separated from the height slot 5. At this time, the headrest mechanism 2 can be moved upward. When the headrest mechanism 2 moves upward as a whole, it will drive the lifting column 4 to move upward, thereby adjusting the height of the headrest mechanism 2;

[0056] To adjust the angle of the first plate 6 and the auxiliary pillow assembly 7, when adjusting, first move the pull rod 99. When the pull rod 99 moves, it will drive the double-sided latch gear 98 to move. When the double-sided latch gear 98 moves, it will stretch the telescopic damping rod 97. When the double-sided latch gear 98 moves, it will disengage from the angle gear 95 and the moving rack 96 respectively. After disengagement, the first plate 6 and the auxiliary pillow assembly 7 can be moved. When the first plate 6 and the auxiliary pillow assembly 7 are translated, the moving block 93 will be driven to slide in the long rod 91. At the same time, the angle gear 95 moves on the moving rack 96. When the angle gear 95 moves, the angle gear 95 rotates, which will also drive the angle shaft 94 to rotate, thereby changing the angle of the first plate 6 and the auxiliary pillow assembly 7, so that the person's head is raised backward and leans on the first plate 6.

[0057] Adjust the angle between the first plate 6 and the auxiliary pillow assembly 7: When adjusting, first, by pulling the pull rod 847, the pull rod 847 will drive the U-shaped unlocking frame 848 to move. When the U-shaped unlocking frame 848 moves, the U-shaped unlocking block 848 begins to squeeze the inclined block 845, and the inclined block 845 will drive the column rod 844 and the moving plate 843 to move. When the moving plate 843 moves, the unlocking damping rod 842 will be stretched. When the column rod 844 moves, one end of the column rod 844 is disengaged from the socket 833. After disengagement, the auxiliary pillow assembly 7 can be rotated to rotate along the first plate 6, so that the top surface of the auxiliary pillow assembly 7 and the top surface of the first plate 6 are located in the same horizontal plane, thereby increasing the area of ​​the entire headrest and preventing the upper part of the person's head from being suspended when leaning against it, giving the person a feeling of discomfort;

[0058] Adjust the first blocking pad assembly 75 and the second blocking assembly 76 in the auxiliary pillow assembly 7 so that the first blocking pad assembly 75, the second blocking pad assembly 76 and the first protection pad 74 form an open V-shape to prevent the person's head from swinging left and right and feeling uncomfortable. When adjusting, first move the pressure plate 7563. When the pressure plate 7563 moves, it will drive the tooth plate 7562 to move. When the tooth plate 7562 moves, it will stretch the engaging damping rod 7561. When the tooth plate 7562 is disengaged from the slot 755, at this time, by rotating the first blocking pad assembly 75 and the second blocking pad assembly 76, when the first blocking pad 751 rotates, it will drive the arc track 754 will slide in the first curved groove 753. When the arc track 754 stops moving, the pressure plate 7563 is released to allow the tooth plate 7562 to reset under the action of the engaging damping rod 7561. After resetting, the arc track 754 is locked. At this time, the second blocking pad assembly 76 is rotated. The working principle of the second blocking pad assembly 76 is the same as that of the first blocking pad 75, so the angle of the first blocking pad 751 can be positioned. After positioning, the first blocking pad 751, the first protection pad 74 and the first blocking pad 751 in the second blocking pad assembly 76 form a V-shape to intercept the person's head, prevent the person's head from swinging left and right, and increase the comfort of the person.
