Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a large-angle telescopic leg rest for a three-row seat. Background Technology

[0002] Most mid-to-high-end car models have leg rests on the seats, but third-row seats rarely have leg rests due to space constraints. This causes inconvenience for passengers in the third row, especially since the lower legs of passengers in different percentiles cannot be effectively supported, resulting in poor comfort.

[0003] Therefore, a three-row seat with a large-angle telescopic leg rest was designed to improve the above problems. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a large-angle telescopic leg rest for a three-row seat, with controllable leg rest angle and length, thereby improving seating comfort.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A three-row seat with a large-angle telescopic leg rest includes a support frame connected to the seat cushion frame, an angle adjustment part connected to the support frame for adjusting the leg rest angle, a telescopic part connected to the angle adjustment part, and a leg rest connected to the telescopic part. The angle adjustment part includes a drive part, and the drive part is connected to a horizontal tube. Both ends of the horizontal tube are connected to active arm linkages. One end of the active arm linkage is connected to a first linkage, and the other end is connected to the support frame. The other end of the first linkage is connected to the telescopic part. A second linkage is rotatably connected to the active arm linkage. One end of the second linkage is connected to the telescopic part, and the other end is connected to a third linkage. The other end of the third linkage is connected to the support frame.

[0007] As a preferred embodiment of this invention, the telescopic part includes a slide rail, and the leg support moves telescopically by means of the slide rail.

[0008] As a preferred embodiment of this invention, the telescopic part includes a lead screw motor, which drives the leg support to telescopically move.

[0009] As a preferred embodiment of this invention, the drive unit is a lead screw motor.

[0010] As a preferred embodiment of this invention, the lead screw motor is mounted on the support frame, and the lead screw of the lead screw motor is connected to the horizontal tube via a connector.

[0011] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are:

[0012] This utility model provides a large-angle telescopic leg rest for a three-row seat, which allows the leg rest to open forward at a large angle and can also be extended and retracted to meet different leg rest opening angle requirements. This ensures that passengers in different percentages can effectively support their lower legs when sitting in the three rows of seats, thus improving comfort. Attached Figure Description

This utility model provides a large-angle telescopic leg rest for a three-row seat, including a support frame 1, an adjusting part 2, a telescopic part 3, and a leg rest 4. The support frame 1 is connected to the seat cushion frame, the adjusting part 2 is connected to the support frame 1, the adjusting part 2 is used to adjust the unfolded angle of the leg rest 4, the telescopic part 3 is connected to the adjusting part 2, and the leg rest 4 is connected to the telescopic part 3 and extends or shortens by the movement of the telescopic part 3.

[0026] The angle adjustment unit 2 includes a drive unit 21, a horizontal tube 22, an active arm connecting rod 23, a first connecting rod 24, a second connecting rod 25, a third connecting rod 26, and a connecting piece 27. The drive unit 21 is preferably a lead screw motor, which is mounted on the support frame 1. The lead screw of the lead screw motor is connected to the horizontal tube 22 via the connecting piece 27. The drive unit 21 is connected to the horizontal tube 22, and the active arm connecting rods 23 are connected to both ends of the horizontal tube 22. The active arm connecting rods 23 are symmetrically arranged at both ends of the horizontal tube 22 and fixedly connected to it. One end of each active arm connecting rod 23 is connected to the first connecting rod 24, and the other end is connected to the support frame 1. The first connecting rod 24 is connected to the telescopic part 3 at one end. The second connecting rod 25 is rotatably connected to the active arm connecting rod 23. One end of the second connecting rod 25 is connected to the telescopic part 3, and the other end is connected to the third connecting rod 26. The other end of the third connecting rod 26 is connected to the support frame 1. That is, the active arm connecting rod 23, the first connecting rod 24, the second connecting rod 25, and the third connecting rod 26 are symmetrically arranged on both sides of the horizontal tube 22. The horizontal tube 22 drives the active arm connecting rod 23 to move, and then the first connecting rod 24, the second connecting rod 25, and the third connecting rod 26 move accordingly. The angle of the leg support 4 can be adjusted by adjusting the length of the connecting rod and the hinge point.

[0027] The telescopic part 3 includes a slide rail 31 and a lead screw motor 32. The leg support 4 moves telescopically by means of the slide rail 31. The lead screw motor 32 drives the leg support 4 to move telescopically. The lead screw motor 32 is fixedly mounted on the telescopic part 3. The lead screw of the lead screw motor 32 is connected to the leg support 4.

[0028] The following will refer to Figures 1 to 6 The working principle of this utility model will be explained.

[0029] The extension of the lead screw motor in the angle adjustment section 2 moves the active arm link 23 forward, driving the first link 24, the second link 25, and the third link 26 forward, thus opening the telescopic section 3 at a large angle to meet the opening angle requirements of different leg rests 4. After the lead screw motor 32 of the telescopic section 3 moves, the leg rests 4 slide and extend through the slide rail 31. This utility model provides a large-angle telescopic leg rest for a three-row seat, which can open the leg rest forward at a large angle and can also extend and retract the leg rest to meet the opening angle requirements of different leg rests. This allows passengers in different percentages to effectively support their lower legs when sitting in the three rows of seats, improving comfort.

[0030] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
