[0002] Car seats are one of the most important parts of cars, which can provide comfortable and safe riding positions for drivers and passengers. With the expansion of the automobile market, customers have higher and higher requirements for the quality and comfort of car seats. In order to provide more comfortable foot support for rear passengers, some front seats are equipped with footrests on the back side so that the feet of rear passengers can be supported on the footrests.

[0003] In the prior art, the footrest mechanism is usually arranged in a gooseneck-type mechanism or a drawer-type mechanism. The gooseneck-type mechanism means that the footrest is folded behind the back of the front seat, and the footrest is connected to the backrest by a gooseneck rod. When in use, the footrest can be rotated outward to unfold. However, such a structure will expose the gooseneck rod inside the footrest when unfolded, affecting the appearance. At the same time, the feet of the rear passengers are also easily touched and interfered with it, affecting the comfort of the passengers. The drawer-type mechanism is to arrange the footrest in parallel to the lower end of the seat frame, and slide it out in parallel to the rear when in use. Such a structural design has a single function and cannot meet the foot support needs of passengers in different postures. In addition, such a structural arrangement will also occupy the space under the front seat cushion, affecting the foot space of the rear passengers. Utility Model Content

[0025] The utility model is further described below in conjunction with embodiments and drawings.

[0026] like Figure 1 As shown, a car seat footrest mechanism comprises a footrest frame 2, a seat cushion frame A, and a backrest frame 1 rotatably mounted at the rear end of the seat cushion frame A. Both ends of the footrest frame 2 are rotatably mounted at the rear lower part of the backrest frame 1. The backrest frame 1 is provided with a driving component 3 and a toothed plate 4 driven to rotate by the driving component 3. Figure 2 It can be seen that the tooth plate 4 and the footrest frame 2 are linked by the first connecting rod 5. The rotation of the tooth plate 4 can drive the footrest frame 2 to flip around the turning point between it and the backrest frame 1 under the linkage of the first connecting rod 5. Figure 7 As shown, in this embodiment, a pedal housing 8 is sleeved on the pedal frame 2 so that the components are not exposed.

[0027] Based on the above structural design, when the footrest function is used, the driving assembly 3 drives the tooth plate 4 to rotate, and under the linkage action of the first connecting rod 5, the footrest frame 2 can be driven to rotate backward and downward to any angle around the turning point between it and the backrest frame 1, so as to meet the support needs of the rear passengers for their feet in different sitting postures, thereby improving the riding comfort. Such a transmission mechanism has a simple and compact structure, has a certain aesthetics, and does not occupy the foot space under the front seat cushion, thus ensuring the moving space for the feet of the rear passengers.

[0028] For example Figure 2 and 3As shown, both ends of the backrest frame 1 are provided with mounting parts 11, and both ends of the footrest frame 2 are provided with ears 21 extending toward the backrest frame 1, and the two ears 21 are rotatably connected to the two mounting parts 11. Such a design facilitates the rotatable mounting of the footrest frame 2 on the backrest frame 1.

[0029] Please refer to Figure 2 The middle part of the toothed plate 4 is rotatably mounted on the backrest frame 1, one end of the first connecting rod 5 is hinged to the lower end of the toothed plate 4, and the other end is hinged to the pedal frame 2. The driving assembly 3 drives the toothed plate 4 to rotate, which can drive the first connecting rod 5 to move, and then drive the pedal frame 2 to rotate backward and downward around the two mounting parts 11.

[0030] Re-attend Figure 2 The drive assembly 3 includes a motor 31 fixedly mounted on one side of the backrest frame 1, and a rotating shaft 32 driven to rotate by the motor 31. A gear 33 is fixedly mounted on the rotating shaft 32, and a toothed portion 41 meshing with the gear 33 is provided on the upper portion of the toothed plate 4. The motor 31 drives the rotating shaft 32 to rotate, driving the gear 33 on the rotating shaft 32 to rotate, thereby driving the toothed plate 4 to rotate around the pivot point in the middle. Figure 4 It can be seen that the hinge point between the lower end of the toothed plate 4 and the first connecting rod 5, the hinge point between the first connecting rod 5 and the pedal frame 2, and the pivot point between the ear 21 and the corresponding mounting portion 11 form a triangular frame. The toothed plate 4 rotates clockwise around the pivot point in the middle thereof, which can drive the pedal frame 2 to rotate backward and downward with the mounting portion 11 as the center (refer to Figure 5 and 6 ), and at the same time, the driving assembly 3 has a self-locking function. When it stops driving, the tooth plate 4 can be kept fixed, that is, the footrest frame 2 can be kept at a fixed angle. The rear passengers can adjust the footrest frame 2 to a horizontal angle or a backward and downward angle according to different postures to meet the comfort support of the feet in different states, thereby improving the riding experience.

[0031] like Figure 2 and 3 As shown, the first connecting rod 5 is located on one side in the width direction of the pedal frame 2, and a second connecting rod 6 symmetrical to the first connecting rod 5 is provided on the other side in the width direction of the pedal frame 2, one end of the second connecting rod 6 is hinged to the pedal frame 2, and a support rod 7 is horizontally placed between the first connecting rod 5 and the second connecting rod 6. When the tooth plate 4 drives the first connecting rod 5 to move, the support rod 7 can synchronously drive the second connecting rod 6 to move, so that the ears 21 at both ends of the pedal frame 2 rotate synchronously around the corresponding mounting parts 11.

[0032] Please refer to Figure 1 and 4 A shaft frame 12 is fixedly mounted on the inner side of the side of the backrest frame 1, and the end of the rotating shaft 32 is rotatably supported on the shaft frame 12. The shaft frame 12 can shield and protect the rotating shaft 32 and the gear 33.

[0033] Through the above structural design, the footrest mechanism can be installed without opening too much avoidance movement space on the rear side of the backrest frame 1. The overall appearance is good, and the structure is compact and simple, which can take into account more layout requirements.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
