Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a headrest assembly with side wing folding function. Background Technology

[0002] Existing headrests mainly fall into the following categories: 1. Fixed headrests, installed in a fixed position on the seat, cannot be adjusted, and cannot adapt to the needs of passengers of different heights; 2. Two-way headrests, whose height can be adjusted manually or electrically to allow passengers of different heights to find a suitable height, but the side wings are usually not adjustable, resulting in weak head support. Therefore, how to make the side wings of the headrest adjustable to ensure that passengers can adjust the side wings to a comfortable position according to their needs has become a technical problem that needs to be solved by those skilled in the art. Currently, some headrests with folding side wings have also been proposed on the market, but they have many internal mechanical parts and complex headrest structures, which not only makes them prone to problems but also increases their manufacturing costs. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention aims to provide a headrest assembly with side wing folding function to solve the problems of complex structure and high manufacturing cost of existing headrests with side wing folding function.

[0004] To achieve the above objectives, this utility model proposes a headrest assembly with side wing folding function, including a headrest frame and two side wing frames. The two side wing frames are respectively connected to the two sides of the headrest frame through a damping hinge structure. The headrest frame and the two side wing frames are completely covered with headrest foam. The headrest foam is covered with a headrest cover. Soft foam is adhered inside the headrest cover at the position corresponding to the front of the headrest frame. The soft foam is embedded in the headrest foam, and its front is flush with the front of the headrest foam. A headrest rod is fixedly connected to the back of the headrest frame, and the two legs of the headrest rod extend downward through the headrest cover.

[0005] The above solution also includes a headrest locking mechanism, which comprises a fixed bracket disposed inside the backrest. Two headrest guide sleeves are provided on the fixed bracket corresponding to the two legs of the headrest rod. Each leg is inserted into one of the headrest guide sleeves. One leg has several slots along its height, with the slot openings facing outwards. The fixed bracket also includes a button mounting base and a lock plate mounting base. An unlocking button is embedded in the front end of the button mounting base. A transmission bracket slides left and right on the lock plate mounting base. The transmission bracket is sleeved on the legs with the slots and has a locking pin to engage with the slots. The headrest guide sleeves have clearance holes at positions corresponding to the slots for the locking pin to pass through. A clearance is provided between the transmission bracket and the corresponding support legs of the headrest rod for the transmission bracket to slide outward. A return spring is provided between the outer end of the transmission bracket and the locking plate mounting seat. The locking plate mounting seat also has guide posts extending forward and backward. An unlocking bracket is movably sleeved on the guide posts. The inner end of the unlocking bracket contacts the rear end of the unlocking button. Both the outer end of the unlocking bracket and the inner end of the transmission bracket have matching guide ramps in contact. Pressing the unlocking button backward moves the unlocking bracket backward along the guide posts. With the cooperation of the two guide ramps, the backward movement of the unlocking bracket moves the transmission bracket outward, thereby disengaging the locking pin from the slot and unlocking the headrest rod. After unlocking, the headrest can be adjusted up and down. After adjustment, the locking pin returns to its original position under the action of the return spring, thus locking the headrest.

[0006] In the above scheme: the locking plate mounting seat is a cavity structure, and the inner wall of the locking plate mounting seat is provided with a limiting groove for accommodating the transmission bracket. The structure is simple and easy to assemble.

[0007] In the above solution: the headrest frame and the two side wing frames are all plastic parts, and the upper end of the headrest rod is welded with a connecting sheet metal, which is fixed to the headrest frame with screws, which is conducive to achieving a lightweight design of the headrest.

[0008] In the above scheme: the headrest frame and the side wing frames are injection molded together, and the damping hinge structure is embedded between the headrest frame and the corresponding side wing frames. The structure is simple, easy to process, and has low processing cost. The headrest foam can be processed by foam injection technology.

[0009] The beneficial effects of this utility model are as follows: Since the two side wing frames are connected to the two sides of the headrest frame through a damping hinge structure, the two side wing frames can be manually folded to adjust the side wing folding of the headrest assembly. Furthermore, the front of the headrest assembly is inlaid with soft foam, further ensuring passenger comfort. In summary, this utility model has a side wing folding function, fewer overall parts, is easy to manufacture, has low cost, and offers high comfort. Attached Figure Description

[0016] Figure 6 This is a structural diagram of the fixed support. Detailed Implementation

[0017] like Figure 1 As shown in Figure 6, a headrest assembly with side wing folding function mainly consists of a headrest frame 1 and two side wing frames 2. The two side wing frames 2 are connected to the two sides of the headrest frame 1 through a damping hinge structure 3.

[0018] The headrest frame 1 and the two side wing frames 2 are entirely covered with headrest foam 4, and the headrest foam 4 is covered with a headrest cover 5. Inside the headrest cover 5, corresponding to the front position of the headrest frame 1, soft foam 6 is adhered. The soft foam 6 is embedded in the headrest foam 4, and its front is flush with the front of the headrest foam 4. A headrest rod 7 is fixedly connected to the back of the headrest frame 1, and the two legs of the headrest rod 7 extend downwards through the headrest cover 5.

[0019] The headrest foam 4 can be processed by foaming technology. Before foaming, a diaphragm agent is sprayed into the soft foam 6.

[0020] Ideally, it should also include a headrest locking mechanism, which includes a fixed bracket 8 located inside the backrest. The fixed bracket 8 has two headrest guide sleeves 9 corresponding to the two legs of the headrest rod. The two legs are inserted into the two headrest guide sleeves 9 one by one. One of the legs has several slots 10 along its height direction, with the slots 10 opening outwards.

[0021] The fixed bracket 8 is also provided with a button mounting base 11 and a lock plate mounting base 12. The front end of the button mounting base 11 is embedded with an unlocking button 13 (the unlocking button 13 has a return spring). The lock plate mounting base 11 is slidably provided with a transmission bracket 14. The transmission bracket 14 is sleeved on the support foot with a slot 10. The transmission bracket 14 is provided with a locking pin 15 to engage with the slot 10. The headrest guide sleeve 9 is provided with a clearance hole for the locking pin 15 to pass through at the position corresponding to the slot 10.

The outer end of the transmission bracket 14 is provided with a return spring 16 between it and the lock plate mounting base 11.

[0022] The locking plate mounting base 11 is also provided with a guide post 17 extending forward and backward. An unlocking bracket 18 is movably sleeved on the guide post 17. The inner end of the unlocking bracket 18 contacts the rear end of the unlocking button 13. The outer end of the unlocking bracket 18 and the inner end of the transmission bracket 14 are both provided with matching guide slopes, and the two guide slopes are in contact.

[0023] Pressing the unlock button 13 backward will cause the unlock bracket 18 to move backward along the guide post 17. With the cooperation of the two guide slopes, the backward movement of the unlock bracket 18 can drive the transmission bracket 14 to move outward, thereby causing the locking pin 15 to disengage from the slot 10 and unlocking the headrest rod 7.

[0024] After the headrest is unlocked, it can be adjusted up and down. After adjustment, the locking pin 15 can be reset by the action of the return spring 16 to lock.
