Description

Technical Field

[0001] This invention relates to the field of automotive seat technology, and more particularly to a flip-up clampable seat leg rest. Background Technology

[0002] Car seat leg rests are typically installed at the front of the seat cushion. They can be adjusted manually or electrically to extend, retract, and change angles according to the occupant's leg length, sitting posture, and different usage scenarios. This provides effective support for the occupant's lower legs, preventing them from being unsupported. It not only distributes pressure on the legs and reduces leg muscle fatigue, but also allows the occupant's lower limbs to be placed more comfortably and relaxed, thereby improving overall riding comfort and safety.

[0003] Most car seat leg rests currently on the market have flat or simple curved surfaces. While they provide some support, they fall short in conforming to the curves of the human leg and achieving more precise support. This results in a gap between the leg rest and the lower leg, causing the lower leg to wobble when the vehicle accelerates, decelerates, or turns. Furthermore, the materials used in existing leg rests generally have low friction, failing to effectively secure the lower leg. This wobble is particularly noticeable when passengers are wearing smooth fabric trousers, severely impacting ride comfort, stability, and safety.

[0004] Therefore, there is an urgent need to design a flip-up, clamping leg rest that can securely hold the occupant's lower legs without taking up additional space, effectively preventing leg swaying and reducing the risk of injury due to loss of balance during emergency braking, sharp turns, and other sudden events. This further ensures passenger safety and improves ride comfort, stability, and safety. Simultaneously, it effectively meets the diverse needs of passengers, enhancing the practicality and user experience of the leg rest. Summary of the Invention

[0030] Most car seat leg rests currently on the market have flat or simple curved surfaces. While they provide some support, they fall short in conforming to the curves of the human leg and achieving more precise support. This results in a gap between the leg rest and the lower leg, causing the lower leg to wobble when the vehicle accelerates, decelerates, or turns. Furthermore, the materials used in existing leg rests generally have low friction, failing to effectively secure the lower leg. This wobble is particularly noticeable when passengers are wearing smooth fabric trousers, severely impacting ride comfort, stability, and safety.

[0031] To address the aforementioned issues, this application provides a flip-up, clamping seat leg rest. This leg rest, without occupying additional space for the lower legs, provides a secure grip, effectively preventing leg movement and reducing the risk of injury due to loss of balance during emergency braking, sharp turns, or other sudden events. This further ensures passenger safety and improves comfort, stability, and overall safety. Furthermore, it effectively meets the diverse needs of passengers, enhancing the practicality and user experience of the leg rest.

[0032] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0033] Example

[0034] Please see Figures 1-6 The flip-up, clamping seat leg rest of this application includes an adjustment component 1, a leg rest component 2, and an inflatable bladder 4. The adjustment component 1 is connected to the seat cushion frame 5 and is used to push the leg rest component 2 to open or retract, ensuring that the leg rest component 2 can be flexibly adjusted in position according to the occupant's needs. The leg rest component 2 is rotatably connected to the adjustment component 1 to support the occupant's legs, accommodating different leg lengths and sitting postures. The inflatable bladder 4 is disposed on the leg rest component 2 and is used to clamp the occupant's legs.

[0035] Specifically, the leg support assembly 2 includes a leg support frame, a first support surface 21, and a second support surface 22; the first support surface 21 and the second support surface 22 are disposed opposite to each other on the two sides of the leg support frame. For example, the first support surface 21 is planar to meet basic planar support requirements. The second support surface 22 is generally m-shaped, including a first support U-shaped groove 221 and a second support U-shaped groove 222. The first support U-shaped groove 221 and the second support U-shaped groove 222 are arranged sequentially in the left-right direction to support and limit the occupant's lower leg. When the occupant places their lower leg on the second support surface 22, the first support U-shaped groove 221 and the second support U-shaped groove 222 can respectively accommodate both sides of the lower leg, effectively reducing the gap between the leg support and the lower leg, and preventing the lower leg from swaying due to acceleration, deceleration, or turning during vehicle operation. By setting up differentiated first support surface 21 and second support surface 22, users can flexibly select and adjust the combination of support surfaces according to their specific usage needs and scenarios, effectively improving the practicality and flexibility of the leg rest.

[0036] Furthermore, several airbags 4 are provided, each positioned inside the walls of the first supporting U-shaped groove 221 and the second supporting U-shaped groove 222. Each airbag 4 is connected to an inflation solenoid valve assembly via a connecting pipe and is inflated and deflated under the action of the inflation solenoid valve assembly. When the occupant needs to fix their lower leg position, the inflation solenoid valve assembly inflates the airbag 4, causing it to expand and tightly clamp the occupant's lower leg, thus providing a stable clamping effect. Conversely, when the occupant needs to adjust or move their lower leg, the inflation solenoid valve assembly releases the gas inside the airbag 4, causing it to contract and release the clamping effect on the lower leg. Furthermore, the surface of the airbag 4 is provided with anti-slip textures. By incorporating anti-slip textures, the friction between the airbag 4 and the occupant's legs is further increased, effectively preventing leg swaying even when the occupant is wearing trousers made of smooth fabric. This reduces the risk of injury due to loss of balance during sudden events such as emergency braking and sharp turns, further ensuring passenger safety.

[0037] The adjustment assembly 1 includes a drive motor 11, a lead screw 12, a push rod 13, and a connecting rod 14. The drive motor 11 is fixedly mounted at the bottom end of the seat cushion frame 5 and is connected to the lead screw 12 for providing power to the lead screw 12. The lead screw 12 is fixed to the bottom end of the seat cushion frame 5 by a nut, and the extension direction of the lead screw 12 is the front-back direction of the seat. When the drive motor 11 drives the lead screw 12 to move, the nut remains stationary, and the lead screw 12 moves in the front-back direction. The lead screw 12 is connected to the push rod 13 to convert the rotational motion of the drive motor 11 into the linear motion of the push rod 13. Specifically, the push rod 13 includes a push rod body 131 and a connector 132. The push rod body 131 is a horizontal bar, and the extension direction of the push rod body 131 is parallel to the width direction of the leg support assembly 2. The lead screw 12 is connected to the central area of ​​the push rod body 131, thereby facilitating the smooth pushing of the leg support assembly. The connector 132 is disposed at both ends of the push rod body 131 and forms a frame shape with one side open with the push rod body 131. The connector 132 is connected to the connecting rod portion 14. For example, the connecting rod portion 14 is provided with a limiting hole, and the connector 132 is inserted into the limiting hole.

[0038] One end of the connecting rod 14 is fixedly connected to the seat cushion frame 5, and the other end is rotatably connected to the leg support assembly 2, for driving the leg support assembly 2 to open or retract. For example, the connecting rod 14 includes a first connecting rod 141 and a second connecting rod 142. One end of the first connecting rod 141 is located at the bottom end of the seat cushion frame 5, and the other end is hinged to one end of the second connecting rod 142. One end of the second connecting rod 142 is hinged to the first connecting rod 141, and the other end is rotatably connected to the leg support assembly 2, thereby allowing the first connecting rod 141 and the second connecting rod 142 to open or retract and fold based on their connected hinge point, and driving the leg support assembly 2 to open or retract. Preferably, to further improve the stability of opening or retracting the leg support assembly, the connecting rods 14 are respectively located on the left and right sides of the leg support assembly, with two connecting rods 14 on any one side. When the drive motor 11 starts and drives the lead screw 12 to rotate, the lead screw 12 moves along the front-to-back direction of the seat through the fixing action of the nut, further transmitting the force to the push rod body 131. Under the push of the lead screw 12, the push rod body 131 drives the connecting rod part 14 to move through the connectors 132 at both ends. Since the connecting rod part 14 is hinged by the first connecting rod 141 and the second connecting rod 142, the connecting rod part 14 can bend or extend accordingly according to the pushing direction and force of the push rod 13, thereby precisely controlling the opening angle and retraction degree of the leg support assembly 2.

[0039] The flip-up, clampable seat leg rest also includes a mounting plate 6; the mounting plate 6 is disposed on the left and right sides of the leg rest assembly 2, and has an movable gap between it and the leg rest assembly 2; one end of the connecting rod portion 14 is connected to the mounting plate 6. By setting the mounting plate 6 and reserving an movable gap between the mounting plate 6 and the leg rest assembly 2, relatively independent and non-interfering movement spaces are provided for the adjustment component 1 and the flip-up component 3, effectively avoiding movement interference problems.

[0040] Furthermore, to facilitate occupants in selecting either the first support surface 21 or the second support surface 22 according to their needs, the flip-up clamping seat leg rest also includes a flipping assembly 3. The flipping assembly 3 is disposed on the leg rest assembly 2 and is used to drive the leg rest assembly 2 to flip; the flipping assembly 3 includes a rotary motor and a rotating shaft; the rotary motor is fixed to the mounting plate 6 and is poweredly connected to the rotating shaft, used to drive the leg rest assembly 2 to flip around the axis of the rotating shaft; the rotating shaft is arranged along the width direction of the leg rest assembly 2 and passes through the mounting plate 6 to connect with the rotary motor. It should be noted that the rotary motor has a self-locking function, thereby effectively improving the load-bearing capacity and stability of the leg rest support.

[0041] Furthermore, the flip-up, clamping leg rest also includes a massage component, which is disposed within the leg rest assembly 2. For example, the massage component comprises several massage units evenly distributed within the leg rest assembly 2. When a passenger places their calves on the leg rest assembly 2, the massage units perform kneading, tapping, and pushing massages on the calves, greatly relieving leg fatigue. It should be noted that the massage component within the leg rest assembly only needs to perform the massage function; the specific structure of the massage component is not limited here.

[0042] Working principle:

[0043] Taking the first support surface 21 facing outward as an example: When the occupant needs to use the flip-up clamping seat leg rest, firstly, the drive motor 11 is started, driving the lead screw 12 to rotate. Since the nut is fixed to the bottom end of the seat cushion frame 5, the lead screw 12 will move forward along the front-back direction of the seat, thereby pushing the push rod body 131 forward. The connectors 132 at both ends of the push rod body 131 drive the connecting rod part 14 to move. Since the connecting rod part 14 is hinged by the first connecting rod 141 and the second connecting rod 142, it will bend or extend accordingly according to the pushing direction and force of the push rod 13 during the pushing process, thereby driving the leg rest assembly 2 to open to a suitable position (such as raising the leg rest assembly forward by 75 degrees, with the first support surface 21 facing upward). When the occupant does not need to use the leg rest, the drive motor 11 rotates in the reverse direction, causing the lead screw 12 to move in the reverse direction. The push rod body 131 then moves in the reverse direction, and through the connector 132, it drives the connecting rod part 14 to retract and fold, thereby driving the leg rest assembly 2 back to its initial position.

[0044] If the occupant chooses the second support surface 22 to support their lower leg, after the leg support assembly opens under the push of the adjustment component 1, the leg support assembly rises forward by 28-57 degrees (the adjustment action is the same as described above, and will not be repeated here). Then, the rotary motor is started, driving the rotating shaft to rotate, thereby causing the leg support assembly 2 to rotate around the axis of the rotating shaft (e.g., rotate 175 degrees), so that the second support surface 22 faces upward. The lower leg is then placed in the first support U-shaped groove 221 and the second support U-shaped groove 222 of the second support surface 22. At this time, the inflation solenoid valve assembly inflates the airbag 4 located on the inner side of the groove wall. The airbag 4 expands and tightly clamps the occupant's lower leg, thereby effectively preventing the lower leg from shaking. Conversely, when it is not necessary to clamp the lower leg, the inflation solenoid valve assembly releases the gas in the airbag 4, causing the airbag 4 to contract, thereby releasing the clamp on the lower leg.

[0045] In addition, during the use of the leg rest, passengers can choose to activate the massage components as needed. Several massage units evenly distributed inside the leg rest component 2 will perform kneading, tapping, and rubbing massage operations on the passenger's calves, greatly relieving the fatigue of the passenger's legs.

[0046] In this embodiment, the flip-up, clamping seat leg rest provided by this application includes an adjustment component, a leg rest assembly, a flipping component, and an inflatable bladder. By setting differentiated first and second support surfaces on the leg rest assembly, and providing an inflatable bladder on the second support surface, the inflation and deflation of the bladder effectively clamps the occupant's lower leg. This not only meets the occupant's different needs for leg rests but also effectively prevents the lower leg from swaying, reducing the risk of injury due to loss of balance in sudden situations such as emergency braking and sharp turns, further ensuring passenger safety. By setting a flipping mechanism, both the first and second support surfaces can be set on the same leg rest frame, meeting the occupant's different usage needs without occupying additional space for the lower leg, thus improving practicality and user experience. Compared to existing technologies, the solution provided in this application can securely hold the occupant's lower legs without occupying additional space for the lower legs, effectively preventing leg swaying and reducing the risk of injury due to loss of balance during sudden events such as emergency braking and sharp turns. This further ensures passenger safety and improves riding comfort, stability, and safety. Simultaneously, it effectively meets the diverse usage needs of passengers, enhancing the practicality and user experience of the leg rest.
