Description

Technical Field

[0001] The utility model relates to the technical field of seat headrests, in particular to a folding headrest shielding mechanism for an automobile seat. Background Art

[0002] The existing car seat headrests on the market, when the seat needs to be laid flat for rest, the car seat headrests will interfere with the rear seats, resulting in the front seat backs not being able to lie completely flat, and there is insufficient space for the front seats to lie flat. When the front seats need to be tilted forward and laid flat to make room in the car, the headrests will also interfere with the front instrument panel. In order to prevent the headrests from interfering with the rear seats or the front instrument panel, it is currently necessary to manually remove the headrest assembly and place it aside before adjusting the seat back to tilt backward or forward to lie flat. When the front seats are returned to their original positions, the headrest assembly needs to be reinstalled, and the operation steps are cumbersome, time-consuming and labor-intensive.

[0003] The invention with application publication number CN118163690A discloses a backward folding electric headrest device, including a driving fixture fixedly mounted on the seat back frame, a driving lifting mechanism rotatably mounted on the driving fixture, a headrest mounting seat hingedly mounted on the driving fixture, and a headrest assembly fixedly mounted on the headrest mounting seat, which can completely fold the headrest backward for storage, with a reasonable spatial layout, solving the problem of cumbersome operation steps caused by manually pulling out the headrest rod and placing it aside before adjusting the front and rear tilt angle of the seat back to lie flat. However, during the folding process of the headrest, the headrest rod will sweep the top surface of the seat back, forming a large gap. If it is not covered, there will be appearance problems such as exposed metal, and there will be problems such as children pinching their hands and foreign objects falling and difficult to clean, and it is impossible to prevent dust, which affects the service life of the device.

DETAILED DESCRIPTION

[0031] In order to better understand the improvements made by the present invention relative to the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] like Figure 6 As shown in FIG. 7 , a folding headrest shielding mechanism for a car seat is shown. A headrest A is mounted on a seat back through a headrest rod 1 and can be folded backward relative to the seat back. A cover B is provided at the position of the mounting hole of the headrest rod 1 corresponding to the seat back, and a through groove is reserved on the cover B for the headrest rod 1 to rotate.

[0033] like Figure 1As shown in FIG. 2 , the cover B is formed by the cover fixing bracket 6, the front cover 7 and the rear cover 8. The cover fixing bracket 6 is fixed on the backrest frame, and the front cover 7 and the rear cover 8 are both installed on the top of the cover fixing bracket 6. The front cover 7 is a "U"-shaped plate, and the middle part is a through groove matching the headrest rod 1. A plurality of connecting buckles are provided at the bottom edge of the front cover 7, and the front cover 7 is fixedly connected to the cover fixing bracket 6 through the connecting buckles. The rear cover 8 is fixed to the rear of the cover fixing bracket 6 through buckles, and a groove matching the headrest rod 1 is provided in the middle of the rear cover 8. When the headrest A is folded, the headrest rod 1 and the rear cover 8 always maintain a gap.

[0034] A shielding mechanism is also provided at the position of the headrest rod 1 corresponding to the mounting hole of the seat back, and the shielding mechanism is located below the cover B. The shielding mechanism includes a rear shielding member 10 and a front shielding member 20. When the headrest A is in the initial position, the headrest rod 1 is against the front end of the through slot, and the rear shielding member 10 can ensure that there is no gap behind the headrest rod 1. When the headrest A is folded backward relative to the seat back, the rear shielding member 10 is linked to move backward together, and the front shielding member 20 is linked to move and ensure that there is no gap in front of the headrest rod 1.

[0035] like Figure 8 As shown, the headrest A is installed on the seat through two headrest rods 1 with the lower ends bent backwards, and the headrest A is folded relative to the seat by driving the motor push rod 3 through the motor assembly 2. The two headrest rods 1 are both equipped with headrest rod fixing assemblies 5 at the rear ends of the bending parts, and a synchronization rod 4 is arranged between the two headrest rod fixing assemblies 5.

[0036] like Figure 3 As shown in FIG. 5 , the front shielding member 20 is hinged on the headrest rod 1. When in the initial state, the front shielding member 20 can rotate forward to avoid collision when in contact with the motor assembly 2. Both headrest rod fixing assemblies 5 are provided with a front shielding member right fixing bracket 18 and a front shielding member left fixing bracket 19 on both sides of the front shielding member 20. When the headrest A is folded backward, the front shielding member 20 rotates backward under the pressure of the foaming member and is limited by the front shielding member right fixing bracket 18 and the front shielding member left fixing bracket 19. When the headrest A is folded, the front shielding member 20 is placed horizontally below the through slot.

[0037] like Fig.10 As shown in FIG. 11 , the rear shielding member 10, the first connecting rod 16 and the second connecting rod 17 are hinged in sequence, the bottom end of the second connecting rod 17 is fixed to the headrest rod fixing assembly 5 or the synchronization rod 4, and the front shielding member 20 is installed at the lower part of the headrest rod 1. In order to ensure the stability of each component during the linkage movement, the first connecting rod 16 is hinged to the second connecting rod 17 by a step bolt 13, and a bushing 14 and a gasket 15 are provided between the first connecting rod 16 and the second connecting rod 17.

[0038] like Fig. 9As shown, the rear shielding member 10 is an "L"-shaped plate composed of a horizontal side and a vertical side. The front end of the horizontal side is provided with an arc surface that fits with the headrest rod 1. The rear shielding member 10 is hinged to the bottom of the rear end of the cover through the rear shielding member fixing pin 9 near the bend. When the headrest A is not flipped over, the horizontal side is placed in the through groove and the front end is in contact with the headrest rod 1, so that there is no gap between the headrest rod 1 and the through groove. The vertical side is provided with two pieces placed on both sides of the rear end of the horizontal side. The lower end of the rear shielding member 10 is hinged to the first connecting rod 16 through the pin shaft 11. The lower end of the rear shielding member 10 is clamped on both sides of the pin shaft 11. The pin shaft 11 is fixed in the hole at the upper end of the first connecting rod 16. In order to facilitate assembly and eliminate assembly errors, the clamping part of the lower end of the rear shielding member 10 is made into an "Ω" shape.

[0039] When the headrest A is folded, the headrest rod 1 drives the second connecting rod 17 to rotate counterclockwise, the lower end of the rear shielding member 10 rotates clockwise, and the front end of the rear shielding member 10 is folded downward, so that the front end of the rear shielding member 10 is hidden under the headrest rod. At the same time, the front shielding member 20 moves upward with the headrest rod 1, so that after the headrest A is folded, the front shielding member 20 blocks the through-slot gap in front of the headrest rod 1.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
