[0001] The utility model relates to the technical field of vehicle seats, and particularly relates to a rotary calf side massage device and a vehicle seat with the device. Background Art

[0002] Vehicle seats are an important part of vehicles. With the improvement of people's living quality, people pay more and more attention to the quality, quality and use feeling of vehicle seats. Especially for passengers who drive or ride for a long time, due to maintaining the same posture for a long time, it is easy to cause physical fatigue and muscle stiffness. In order to improve the comfort of vehicle seats, vehicle seats with leg massage functions have been introduced on the market to relieve the fatigue caused by long-term driving or riding of passengers.

[0003] In the prior art, leg massage mechanisms are usually divided into two types. One is a massage mechanism arranged on the surface of the seat leg rest, which can only massage the back side of the calf and cannot realize the massage of the side of the calf, and the massage has limitations; the other is a massage mechanism that can wrap both sides of the calf. Although this massage mechanism can relax the muscles on both sides of the calf, it has the defect of large volume, will occupy the foot space of the passenger, and affect the comfort of the passenger's ride. Summary of the Utility Model

[0004] In view of this, one of the purposes of the present utility model is to provide a rotary calf side massage device, which can massage the side of the passenger's calf and does not occupy the foot space of the passenger when not in use.

[0030] The present invention will be further described below in conjunction with embodiments and the accompanying drawings.

[0031] As Figure 6 shown, an automotive seat includes a seat frame B, and a rotary calf side massage device is installed on the front side of the seat frame B. The rotary calf side massage device includes a leg support assembly 1, and the leg support assembly 1 is rotationally assembled at the front end of the seat frame B. Again, as Figure 1 and 2 shown, three groups of baffles 2 are rotationally assembled on the leg support assembly 1. The three groups of baffles 2 are arranged in sequence along the width direction of the leg support assembly 1, and the rotation center lines of the three groups of baffles 2 all extend along the width direction of the leg support assembly 1. A driving mechanism for driving the rotation of the baffle 2 is further provided on the leg support assembly 1. Under the control of the driving mechanism, the baffle 2 can be switched between the upper side and the lower side of the leg support assembly 1.

[0032] Refer to Figure 7 and Figure 8, after the three groups of baffles 2 are rotated to the upper side of the leg rest assembly 1, an accommodation groove a for placing the user's calves can be formed between two adjacent groups of baffles 2. In this embodiment, the accommodation grooves a are all rectangular grooves. Among the three groups of baffles 2, massage components 4 are installed on the inner sides of the baffles 2 on both sides and on both sides of the middle baffle 2. When the massage components 4 work, the two sides of the occupant's calves can be massaged.

[0033] When the occupant needs to use the calf massage function, the drive mechanism drives the three groups of baffles 2 to rotate upward to the upper side of the leg rest assembly 1. The occupant's calves can be respectively placed in the two accommodation grooves a, and the three groups of baffles 2 can sandwich the two sides of the calves. When the massage components 4 work, the two sides of the calves can be massaged. When the calf massage function is not in use, the three groups of baffles 2 can be rotated downward to the lower side of the leg rest assembly 1, which will not occupy the foot space of the occupant and ensure the comfort of the occupant during riding. In addition, by rotating the leg rest assembly 1, the leg rest assembly 1 can be used as a leg rest, having the advantages of reasonable structural layout and good overall appearance.

[0034] As Figure 8 shown, in this embodiment, the massage components 4 are all massage air bags. The number of massage air bags is four, which are respectively arranged on the inner surface of the baffles 2 on both sides and on the two surfaces of the middle baffle 2. In the unused state, the massage air bags are not inflated, and the surfaces of the respective baffles 2 are flat. When in use, the massage air bags are inflated (refer to Figure 9 ), and the four massage air bags can strongly sandwich the two sides of the calves. By cyclically inflating and deflating the massage air bags, the two sides of the calf A can be massaged by pinching and kneading (refer to Figure 10 ), having the technical advantage of good massage effect.

[0035] Please refer to Figure 1 , at the positions of the leg rest assembly 1 corresponding to the accommodation grooves a, assembly notches 11 are provided. On the assembly notches 11, massage mechanisms for the rear sides of the calves, such as air bag type massage mechanisms or roller type massage mechanisms, can be selected and installed according to requirements. When used in cooperation with the massage air bags on the side parts of the calves, the calves of the occupant can be massaged in all directions, enabling the legs of the occupant to be thoroughly relaxed.

[0036] Refer to Figure 3 and 4 again, a rotating shaft 3 extending along the width direction of the leg rest assembly 1 is provided on the leg rest assembly 1. One end of each of the three groups of baffles 2 is fixedly sleeved on the rotating shaft 3. When the drive mechanism drives the rotating shaft 3 to rotate, the three groups of baffles 2 can be driven to rotate.

[0037] Furthermore, as Figure 3 and 5As shown, the rotating shaft 3 is arranged at the front end of the leg rest assembly 1, and the rotating shaft 3 is connected to one of the corner positions b of the baffle 2. The two sides of the corner position b have a first side 21 and a second side 22 that form an acute angle with each other. The rotation direction of the baffle 2 from the lower side of the leg rest assembly 1 to the upper side of the leg rest assembly 1 is referred to Figure 3 , in combination with Figure 3 and Figure 4 As shown, when the baffle 2 is rotated and retracted under the leg rest assembly 1, the first side 21 is parallel to the upper surface of the leg rest assembly 1. When the baffle 2 is rotated upward to the use position on the upper side of the leg rest assembly 1, the second side 22 is parallel to the upper surface of the leg rest assembly 1. Since the first side 21 and the second side 22 form an acute angle with each other, therefore, the baffle 2 can be switched between the upper side and the lower side of the leg rest assembly 1 with the smallest rotation angle, so that when the baffle 2 is retracted under the leg rest assembly 1, it will not occupy too much internal space of the leg rest assembly 1, and the leg rest assembly 1 can be more thinly integrated at the front end of the seat frame B, further improving the compactness of the entire device structure and ensuring the activity space of the occupant's feet and the riding experience.

[0038] Please refer to Figure 4 , in this embodiment, the driving mechanism is a motor 5 that drives the rotation of the rotating shaft 3, or the driving mechanism can also be an electric angle adjuster.

[0039] In addition to the above implementation manner, among the three groups of baffles 2, the middle baffle 2 is composed of two plate bodies.

[0040] Finally, it should be noted that the above description is only the preferred embodiment of the present invention. Under the inspiration of the present invention, those of ordinary skill in the art can make various similar representations without violating the purpose and claims of the present invention, and such transformations all fall within the protection scope of the present invention.
