Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a pneumatic flip-up sleep headrest for automotive seats. Background Technology

[0002] With the booming development of the automotive industry, people's demands for car seat functions are becoming increasingly diversified and higher. Cars are gradually becoming places for users to rest temporarily, and during this rest, users have specific needs for head support. On the one hand, users sometimes need to tilt their heads back slightly to relieve neck fatigue; on the other hand, they need to provide lateral head support so that users can rest their heads in a comfortable position.

[0003] However, existing sleep headrests on the market have many shortcomings. Some sleep headrests achieve lateral support by adding hinged flaps on both sides, but the hinges have a fixed rotational torque. If the torque is too high, it will make operation inconvenient for users; if the torque is too low, it may result in insufficient lateral support. Moreover, different customers have different torque requirements, and traditional sleep headrests cannot effectively solve this problem. In addition, most existing flip headrests on the market are mechanical structures, with a toothed rotating component as their core. The headrests need to be manually adjusted and only have a few fixed positions. This design not only produces a lot of noise during operation but also cannot achieve stepless adjustment, failing to meet the diverse needs of users. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention aims to provide a pneumatic flip-up sleep headrest for car seats, so as to solve the problems of inconvenient operation and inflexible adjustment in terms of lateral support and flip adjustment of existing sleep headrests, and provide users with a more comfortable and convenient head support experience.

[0005] To achieve the above objectives, this utility model proposes a pneumatically folding sleep headrest for automobile seats, comprising a headrest assembly and a folding mechanism. The headrest assembly includes a headrest cover, foam, side wing supports, side wing airbags, and a front frame arranged sequentially from front to back. The side wing supports include left and right side wing supports arranged opposite each other, and the side wing supports are rotatably connected to the front frame via vertical pivots. Each side wing support is equipped with a torsion spring between itself and the front frame, and the torsion spring has a torque that drives the corresponding side wing support to rotate continuously towards the front frame. The side wing airbags also include left and right side wing airbags arranged opposite each other, and the side wing airbags are respectively positioned between the side wing supports and the front frame. Between the frames, the headrest cover sequentially wraps the foam, side wing support, side wing airbag and front frame from front to back, and is fastened to the rear end of the front frame. The flipping mechanism includes a rotating component, rear airbag, rear frame and headrest back cover arranged sequentially from front to back. The top and rear end of the rotating component is rotatably connected to the rear frame through a transverse pivot. The rear airbag is arranged between the rotating component and the rear frame, and a return spring is provided between the rotating component and the rear frame. The return spring has the torque to drive the rotating component to rotate in the direction of the rear frame. The side wing airbag and the rear airbag are both equipped with air pipes and air pumps. The headrest back cover sequentially wraps the rear frame, rear airbag and rotating component from back to front, and is fastened to the front frame.

[0006] The above solution also includes a front cover with a central cutout. The front cover is fastened to the front frame from back to front to cover the outer edge of the headrest cover, thereby avoiding the exposure of any rough edges, loose threads, or irregular edges that may appear on the outer edge of the headrest cover.

[0007] The above solution also includes an air pump and two headrest rods. Both headrest rods are hollow tubes with open ends, their upper ends fixed to the rear frame and their lower ends fixed inside the car seat. The headrest cover has clearance holes for the headrest rods to pass through. The air pump is installed inside the car seat, with its two air pipes passing through the two headrest rods from bottom to top, connecting to the rear airbag and then to the corresponding side wing airbags. This design cleverly integrates the air pump into the car seat, concealing the air pipes within the headrest rods. This layout significantly saves installation space inside the headrest and avoids the clutter caused by exposed air pipes, resulting in a cleaner and more aesthetically pleasing overall appearance of the car seat and improving the overall quality of the vehicle interior.

[0008] In the above design: Each of the two headrest rods has a toothed groove at its upper end. The rear frame has a cylindrical feature on each side, into which the headrest rods are inserted. The rear frame also has a through hole on each side of the corresponding cylindrical feature, and each through hole is equipped with a pin. The pin passes through the through hole and engages with the toothed groove of the corresponding headrest rod, thus achieving a fixed connection between the rear frame and the headrest rods. The toothed groove and pin design results in a simple structure and convenient assembly / disassembly.

[0009] The above solution also includes a front cover for the mechanism, which is a U-shaped piece that fastens to the rear frame from front to back to cover the gap between the rotating part and the headrest back cover, thus preventing the gap from being exposed and affecting the aesthetics of the headrest.

[0010] In the above solution, both the side wing airbags and the rear airbags are equipped with several mounting holes. The side wing airbags are mounted to the front frame through these holes, and the rear airbags are mounted to the rear frame through these holes. This mounting hole design greatly simplifies the installation process of the side wing airbags and rear airbags, eliminating the need for complex tools or cumbersome fixing operations, significantly reducing installation time and improving production efficiency.

[0011] In the above scheme: the rotating component is provided with two guide arms facing each other to the left and right. The rear frame is provided with guide grooves that match each guide arm. When the rotating component flips around the rear frame, the guide arm can slide along the corresponding guide groove to limit the swing path of the rotating component, thereby preventing the headrest from swinging randomly. That is, the guide arm and the guide groove work together to guide the headrest to flip according to the designed trajectory.

[0012] The beneficial effects of this utility model are: Inflating and deflating the side airbags allows the headrest to adjust to either a lower center and higher sides or return to its initial position, and it can remain in any position during adjustment. This design allows for flexible adjustment based on different users' head shapes and sleeping postures, providing a more fitting and comfortable head support and effectively improving seating comfort. In addition to side wing adjustment, the inflation and deflation of the rear airbag also drives a rotating component to rotate around its axis and reset, similarly remaining in any position during adjustment. This means the headrest can not only be adjusted to the left and right sides but also to the front and back, providing users with multi-dimensional headrest adjustment options to better meet diverse needs for headrest angle and shape in different scenarios. The side wing support components are equipped with torsion springs, and the rotating component is equipped with a return spring. After the side wing and rear airbags are deflated, the torsion springs and return springs automatically drive the corresponding components to rotate in the opposite direction back to their initial positions. This automatic reset design eliminates the need for users to manually return the headrest to its original position, making operation more convenient and improving ease of use and efficiency.

[0023] like Figure 1 As shown in Figure 10, a pneumatic flip-up sleep headrest for car seats mainly consists of a headrest assembly 1 and a flipping mechanism 2.

[0024] The headrest assembly 1 includes, from front to back, a headrest cover 3, foam 4, side wing supports 5, side wing airbags 8, and a front frame 9. The side wing supports 5 include left and right side wing supports 5 arranged opposite each other. Each side wing support 5 is rotatably connected to the front frame 9 via a vertical pivot, and each side wing support 5 is equipped with a torsion spring 6 between itself and the front frame 9. The torsion spring 6 has a torque that drives the corresponding side wing support 5 to rotate continuously in the direction of the front frame 9. The side wing airbags 8 also include left and right side wing airbags 8 arranged opposite each other, positioned between the side wing supports 5 and the front frame 9. The headrest cover 3 sequentially wraps around the foam 4, side wing supports 5, side wing airbags 8, and front frame 9 from front to back, and is fastened to the rear end of the front frame 9.

[0025] When the side airbags 8 are inflated, they expand and lift the side support 5, along with the foam 4 and the cover 3, making the headrest lower in the middle and higher on both sides. When the side airbags 8 are deflated, the side support 5 rotates in the opposite direction under the action of the front torsion spring 7, and the headrest gradually returns to its initial state, completing one cycle of adjustment. The headrest can stay in any state during this process.

[0026] The flipping mechanism 2 includes a rotating component 13, a rear airbag 15, a rear frame 17, and a headrest cover 20 arranged sequentially from front to back. The top rear end of the rotating component 13 is rotatably connected to the rear frame 17 via a transverse pivot. The rear airbag 15 is positioned between the rotating component 13 and the rear frame 17, and a return spring 12 is provided between the rotating component 13 and the rear frame 17. The return spring 12 has the torque to drive the rotating component 13 to rotate in the direction of the rear frame 17. Both the side airbags 8 and the rear airbag 15 are equipped with air pipe pumps 16, which are controlled by an electronic control system. The headrest cover 20 wraps around the rear frame 17, the rear airbag 15, and the rotating component 13 sequentially from back to front, and is then fastened to the front frame 9.

[0027] When the rear airbag 15 is inflated, it will push up the rotating part 13 and make it rotate around the upper pivot 14 at a certain angle; when the rear airbag 15 is deflated, the rotating part 13 rotates in the opposite direction under the action of the rear return spring 12 and gradually returns to the initial state, completing one cycle of adjustment. The headrest can stop at any state in this process.

[0028] Ideally, it also includes a front cover 10 with a central cutout, which is fastened to the front frame 9 from back to front to cover the outer edge of the headrest cover 3, thereby preventing any rough edges, loose threads, or irregular edges from being exposed (the outer edge of the headrest cover 3 is fixed to the back of the front frame 9 by a fastening structure).

[0029] Ideally, it also includes two headrest rods 18, both of which are hollow tubes open at both ends. The upper ends of each rod are fixed to the rear frame 17, and the lower ends are fixed inside the car seat (specifically, the lower end of each headrest rod 18 has several locking grooves that can cooperate with the "headrest guide sleeve" on the car seat for adjusting the headrest height). The headrest back cover 20 has clearance holes for the headrest rods 18 to pass through. An air pump 16 is installed inside the car seat. The two air pipes of the air pump 16 pass through the two headrest rods 18 from bottom to top, and after exiting, they connect to the rear airbag 15 and to the corresponding side wing airbag 8. This design cleverly integrates the air pump 16 inside the car seat and cleverly hides the air pipes inside the headrest rods 18. This layout greatly saves installation space inside the headrest and avoids the clutter caused by exposed air pipes, making the overall appearance of the car seat cleaner and more aesthetically pleasing, and improving the overall quality of the car interior environment.

[0030] Ideally, each of the two headrest rods 18 has a toothed groove at its upper end, and each side of the rear frame 17 has a cylindrical feature. The two headrest rods 18 are inserted into the corresponding cylindrical features. Each side of the rear frame 17 has a through hole located on the corresponding cylindrical feature. Each through hole is equipped with a pin 19, which passes through the through hole and engages with the toothed groove of the corresponding headrest rod 18, thus achieving a fixed connection between the rear frame 17 and the headrest rods 18. The toothed groove and pin design results in a simple structure and convenient assembly and disassembly.

[0031] Ideally, it also includes a mechanism front cover 11, which is a U-shaped piece that fastens to the rear frame 17 from front to back to cover the gap between the rotating part 13 and the headrest back cover 20, so as to avoid the gap being exposed and affecting the aesthetics of the headrest.

[0032] Ideally, both the side airbags 8 and the rear airbag 15 are provided with several mounting holes 21. The side airbags 8 are mounted to the front frame 9 through the mounting holes 21, and the rear airbag 15 is mounted to the rear frame 17 through the mounting holes 21. The design of the mounting holes 21 makes the installation process of the side airbags 8 and the rear airbag 15 extremely simple, without the need for complicated tools or cumbersome fixing operations, greatly shortening the installation time and improving production efficiency.

[0033] Ideally, the rotating component 13 is provided with two guide arms 13a facing each other to the left and right, and the rear frame 17 is provided with guide grooves 17a that match each guide arm 13a. When the rotating component 13 flips around the rear frame 17, the guide arm 13a can slide along the corresponding guide groove 17a to limit the swing path of the rotating component 13, thereby preventing the headrest from swinging randomly. That is, the guide arm 13a and the guide groove 17a work together to guide the headrest to flip according to the designed trajectory.
