Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a two-way headrest. Background Technology

[0002] Car headrests serve to support the head and relieve fatigue. As an important component of the seat, and given the difference in height between drivers and passengers, most car headrests are height-adjustable. However, current adjustment methods require both hands, or even two people, to smoothly adjust the headrest height upwards or downwards, which is inconvenient and makes it difficult to adjust to the most comfortable position.

[0003] Therefore, a two-way headrest needs to be designed to improve the above problems. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a two-way headrest that can unlock two headrest rods with a single button, allowing the headrest height to be smoothly adjusted upwards or downwards to a comfortable position.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A two-way headrest includes a faceplate, a comfortable soft cotton, a headrest foam, a frame, and a headrest rod. A housing is connected to the rear side of the frame, and the housing has a button for unlocking the headrest. A guide is provided on the frame, and a locking wire is provided on the guide. The headrest rod passes through the guide and is fixed in position by the locking wire. A crossbeam is provided on the frame, one end of which is connected to the button. The crossbeam is engaged with the locking wire. A return spring is provided on the crossbeam for resetting the crossbeam. A positioning pin is provided on the headrest rod, and the positioning pin moves within a groove in the guide.

[0007] As a preferred embodiment of this utility model, the button part includes a button body, a button spring, and a button cover.

[0008] As a preferred embodiment of this utility model, a return spring fixing part is provided on the crossbeam.

[0009] As a preferred embodiment of this utility model, the reset spring fixing part includes an end fixing member and a limiting member.

[0010] As a preferred embodiment of this utility model, the limiting member has an arc-shaped groove formed on it.

[0011] As a preferred embodiment of this invention, the housing is a rear housing located behind the headrest.

[0012] As a preferred embodiment of this invention, the rear housing is a plastic rear housing.

[0013] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are:

[0014] (1) The present invention provides a two-way headrest that can unlock two headrest rods with one button, and can smoothly adjust the headrest height to a comfortable position by going up or down. This allows people of different heights to adjust the headrest height so that their heads can face the headrest directly. In the event of a rear-end collision, this can better protect the head and neck of the driver and passengers and improve safety.

[0015] (2) The two-way headrest of this utility model has a simple structure, which helps to reduce costs. It also uses a plastic back shell, and the headrest has a novel shape, is firmly fixed, and meets regulatory requirements. Attached Figure Description

[0025] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0026] Reference Figures 1 to 4 , Figure 1 This is a perspective view of an example of this utility model. Figure 2 This is an exploded view of an example of this utility model. Figure 3 This is a perspective view of a portion of the structure of an example of this utility model. Figure 4This is another perspective view of the structure of an example of this utility model. The utility model provides a two-way headrest, including a faceplate 1, a comfortable soft cotton 2, a headrest foam 3, a frame 4, a headrest rod 5, a shell 6, a button part 7, guide members 8, a locking wire 9, and a crossbeam 10. The faceplate 1, the comfortable soft cotton 2, and the headrest foam 3 are sequentially connected to the frame 4 to form a fixed structure. The shell 6 is connected to the rear side of the frame 4. The shell 6 is a rear shell located behind the headrest. The shell 6 is preferably a plastic rear shell. The shell 6 has a button part 7 for unlocking the headrest. The button part 7 includes a button body 71, a button spring 72, and a button cover 73. Two guide members 8 are longitudinally arranged on the frame 4. The headrest rod 5 passes through the guide members 8. The guide members 8 are equipped with... There is a locking wire 9, which can be inserted into the groove of the headrest rod 5 to fix the height position of the headrest. The headrest rod 5 is provided with a positioning pin 51, which moves in the slide groove 81 of the guide member 8, thereby limiting the distance of the headrest's vertical movement. The crossbeam 10 is set on the frame 4 and can slide laterally. One end of the crossbeam 10 is connected to the button part 7, and one end of the locking wire 9 is engaged with the crossbeam 10. After pressing the button part 7, the crossbeam 10 is driven to slide, and the crossbeam 10 drives the locking wire 9 to move, separating the locking wire 9 from the headrest rod 5, thus unlocking the headrest rod 5 vertically. The crossbeam 10 is provided with a return spring 101 for resetting the crossbeam 10. One end of the return spring 101 is connected to the reset crossbeam 10, and the other end is connected to the frame 4.

[0027] In one embodiment, a reset spring fixing part 102 is provided on the crossbeam 10. The reset spring fixing part 102 includes an end fixing member 1021 and a limiting member 1022. An arc-shaped groove 10221 is formed on the limiting member 1022. Multiple limiting members 1022 can be provided. When multiple limiting members are provided, the orientation of the arc-shaped groove 10221 can be different so that the reset spring 101 is located in the reset spring fixing part 102.

[0028] The following will refer to Figures 1 to 4 The working principle of this utility model will be explained.

[0029] When button 7 is pressed, the crossbeam 10 slides, and the crossbeam 10 moves the locking wire 9. The locking wire 9 separates from the headrest rod 5, and the headrest rod 5 is unlocked. When button 7 is released, the crossbeam 10 is reset by the return spring 101, and the locking wire 9 is locked back to the headrest rod 5 by its own elastic deformation.

[0030] This utility model discloses a two-way headrest that can be unlocked with one button, allowing for easy upward or downward adjustment of the headrest height to a comfortable position. This enables passengers of different heights to adjust the headrest height so that their heads are directly facing the headrest, thus better protecting the head and neck of drivers and passengers in the event of a rear-end collision and improving safety. The structure is simple, which helps reduce costs, and the use of a plastic back shell results in a novel headrest design that is securely fixed and complies with regulatory requirements.

[0031] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
