Description

Technical Field

[0001] This utility model relates to the field of leg support technology, specifically to a safe folding car leg support device. Background Technology

[0002] Car leg rests are typically installed on the front of the car seat. They can be folded down or unfolded for support and are usually optional accessories. Their main purpose is to support the passenger's legs, preventing them from dangling and enhancing comfort. However, most leg rests on the market only offer different support angles. Once a certain angle is selected, the leg rest, along with the angle adjustment arm, backrest, and floor, forms a relatively fixed position, preventing it from retracting or moving. In the event of a serious collision, because the leg rest is in a fixed position, the impact will compress the legs, leaving them without any cushioning. This results in significant leg injury and fails to effectively protect the leg safety of passengers. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Example 1

[0024] As each Figure 1-4 As shown, a safe folding car leg rest device includes a leg rest support 1 and a connecting bracket. The connecting bracket includes a flip-up part 2, a back plate 3, a base plate 4, and an angle adjustment arm 5 installed on the back of the leg rest support. One end of the back plate 3 is fixedly connected to the base plate 4, and the other end is rotatably connected to the flip-up part 2. The base plate 4 can be installed on a hardware bracket under the car seat or placed directly on the seat floor mat.

[0025] The connecting bracket also includes a retraction device 6, which is installed inside the flip-up component 2 and is installed horizontally. The retraction device 6 includes an elastic tension member 61, a movable component 62 installed on the movable slide 22, and an adjustable force member 63. One end of the elastic tension member 61 is connected to the movable component 62, and the other end is connected to the adjustable force member 63. The elastic tension member 61 can be one or more springs with a diameter of 2.5-3 mm, an outer diameter of 14 mm, and a length of 115 mm, or it can be a rubber band, etc. The movable component 62 is movably connected to the angle adjustment arm 5. The flip-up component 2 is provided with a first side plate 21, and the movable slide 22 is provided on the first side plate 21. The adjustable force component 63 includes a first panel 632 with screw holes 631, a second panel 633 with screw holes 631, and an adjustable force screw 634. The first panel 632 is fixedly installed inside the flip-up component 2. The first panel 632 and the second panel 633 are adjustablely connected by the adjustable force screw 634 passing through the screw holes 631. The second panel 633 is fixedly connected to the elastic tension component 61. When the vehicle is impacted, the legs will experience a large impact force, causing the legs to press downward against the leg support component 1. Due to the fixed connection between the angle adjustment arm 5 and the movable component 62, and the elastic effect of the elastic tension component 61, the movable component 62 will slide down along the movable slide 22. At the same time, the flip-up component 2 will retract downward along with it, which helps to alleviate the impact force on the legs from the front, thereby avoiding or reducing injury to the passenger's legs. In addition, because people's weights vary, the force of support on the legs also varies, so it is necessary to adjust the retraction support strength of the retraction device 6. When the adjustable force screw 634 is loosened, the length of the elastic tension member 61 will become shorter, and the leg support member 1 will bear less support for the legs, which is suitable for lighter passengers; when the adjustable force screw 634 is tightened, the length of the elastic tension member 61 will become longer, and the leg support member 1 will bear more support for the legs, which is suitable for heavier passengers.

[0026] The back plate 3 is provided with a liftable component. The top of the liftable component 7 is provided with connecting ears 71 on both sides. The liftable component 7 is rotatably connected to the flip-up component 2 through the connecting ears 71. One end of the angle adjustment arm 5 is movably connected to the movable component 62, and the other end is rotatably connected to the connecting ears 71 of the liftable component 7.

[0027] Because the distance between the car seat and floor mat varies depending on the car model, the distance between the hardware bracket under the car seat and the car seat also varies. The liftable component 7 is provided with several liftable slides 72, and the back panel 3 is provided with several liftable mounting holes 31 and several left-right movable mounting holes 32. The height can be adjusted according to the needs of different car models by using the liftable slides 72 on the liftable component 7 and the liftable mounting holes 31 on the back panel 3. Because the seat positions vary in different car models, the installation positions of the base plate 4 and the back panel 3 will change depending on the car model. To solve this problem, the base plate 4 of this invention includes a third panel 41 and a second side plate 42 perpendicular to the third panel 41. The second side plate 42 is provided with several left-right movable mounting holes 43. The left-right movable mounting holes 43 on the second side plate 42 are matched with the left-right movable mounting holes 73 on the liftable component 7, allowing adjustment of the left-right position of the liftable component 7 and the base plate 4 to suit different car models.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is provided with a retractable device on the connecting bracket, which adds a retractable function to the car leg support device. When the vehicle is involved in a collision, when the vehicle is subjected to the impact force and squeezes the passenger's legs, the leg support will retract downward, which will buffer the compression of the legs and solve the safety hazards of the existing leg support device. It effectively avoids or reduces the injury to the legs of the driver and passengers when the vehicle is involved in a dangerous collision. Example 2

[0029] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the retraction device 6 is installed inside the liftable component 7, which is a vertical installation method. The liftable component 7 is provided with a first side plate 73, the movable slide 74 is provided on the first side plate 73, the adjustable force component 63 includes a first panel 632 with screw holes 631, the first panel 632 is fixedly installed inside the liftable component 7, one end of the angle adjusting arm 5 is movably connected to the movable component 62, and the other end is rotatably connected to the flip-up component 2.

[0030] The above is the preferred embodiment of this utility model. Simple modifications and substitutions made by those skilled in the art are within the protection scope of this utility model.
