It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0018] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0019] This utility model provides a seamless seat depth adjustment mechanism for automotive seats. It utilizes a mechanical linkage mechanism including a lead screw motor, metal slide rail, flip cover, flip cover reset handle, and handle torsion spring to achieve stepless adjustment of seat depth. The flip cover compensates for insufficient material in the seat cushion extension area, solving the seam problem of traditional seat depth designs. This mechanism supports modular adaptation of front and rear seats, meeting multi-stroke adjustment needs and ensuring stepless adjustment of the car seat cushion depth, guaranteeing both comfort and aesthetics.

[0020] like Figures 1-7As shown, the present invention relates to a seamless seat depth adjustment mechanism for automotive seats, comprising a seat depth sliding mechanism, a flip cover reset mechanism, and a motor assembly.

[0021] The seat depth sliding mechanism consists of a seat depth sliding body 1 and a flip cover 3. The flip cover 3 is snapped onto the seat depth sliding body 1 and can flip outward around the seat depth sliding body 1 under the action of external force. The seat cover is connected to the flip cover 3.

[0022] The flip cover reset mechanism consists of a flip cover reset handle 4, a handle spring 5, a metal slide rail 6, and a handle fixing bolt 7. The handle spring 5 is installed in the limiting groove of the flip cover reset handle 4.

[0023] The handle fixing bolt 7 passes through the flip cover reset handle 4 and the handle spring 5 and is connected to the fixing nut, fixing the flip cover reset handle 4 below the metal slide 6.

[0024] The seat depth sliding mechanism and the flip cover reset mechanism are assembled together by bolts to form a seat depth movement mechanism. The seat depth movement mechanism is slidably assembled with the seat depth plastic U-shaped slide rail 8 via a metal slide rail 6 to form a seat depth sliding body assembly. The seat depth sliding body assembly is assembled with the seat depth fixing bracket 9 via seat depth sliding body fixing bolts 2.

[0025] The motor 11 is fixed to the motor mounting bracket 12 by the first motor fixing bolt 10, forming a motor assembly. The motor assembly is connected to the seat depth fixing bracket 9 by the second motor fixing bolt 13. The motor lead screw is connected to the metal slide rail 6.

[0026] The process of unfolding the seat depth is as follows: Since the motor assembly is connected to the seat depth fixing bracket 9 and the lead screw is connected to the metal slide rail 6, the motor drives the metal slide rail 6 to move in the opposite direction along X, the seat depth sliding body 1 moves forward, the protective cover is stretched, the flip cover 3 flips to compensate for the protective cover, and the seat depth is fully unfolded.

[0027] The seat depth retraction process is as follows: Driven by the motor, the metal slide 6 retracts and moves in the positive X direction. The seat depth sliding body 1 retracts, and the flip cover reset handle 4 contacts the seat depth plastic U-shaped slide 8. The flip cover reset handle 4 rotates and pulls the flip cover 3 to retract and reset, and the seat depth is closed.

[0028] Specifically, the metal slide rail 6 has a thickness of 2.5 mm and dimensions of 28 × 12 mm. The seat depth sliding body 1 has a thickness of 2.5 mm and dimensions of 30 × 14 mm.

[0029] The motor 11 is a Shenghuabo ball screw motor, and the motor 11 is fixed to the motor mounting bracket 12 by two first motor fixing bolts 10. The size of the first motor fixing bolts 10 is M5×26.

[0030] The handle spring 5 has a shaft diameter of 2.2 mm. The handle fixing bolt 7 has a size of M6×30.

[0031] The thickness of the flip cover reset handle 4 is 2.5mm, and the dimensions are 131×26.5.

[0032] The flip cover 3 has a thickness of 2.5 mm and a size of 34×6.

[0033] This utility model relates to a seamless seat depth adjustment mechanism for automotive seats. The seat depth extension stroke is 48±3mm, the single-unit top output force is ≥200N, the operating durability cycle test is 2000 cycles, and the seat depth strength is F=1000, Fz≤20mm; F=500, Fz≤10mm.
