When the top screw 41 does not rotate and the leg rest assembly 2 and the seat cushion assembly 1 are located in non-parallel positions, the leg rest assembly 2 and the seat cushion assembly 1 are relatively locked, and the leaf spring 51 is pulled with the top screw 41 to store elastic force. When the top screw 41 does not rotate, the lock between the leg rest assembly 2 and the seat cushion assembly 1 is released, and the elastic force stored in the leaf spring 51 is released through the reset rod, and the reset rod drives the leg rest frame 21 to rebound, so that the leg rest assembly 2 returns to a position parallel to the seat cushion assembly 1. The adjustable car seat cushion of the utility model realizes the reset of the leg rest assembly 2 through the reset assembly, and the setting method of the reset rod and the leaf spring 51 is simple and the structure is reliable, which reduces the difficulty of storage and further improves the user experience.

[0028] Specifically, when using the adjustable car seat cushion in the utility model, first place it on the car seat, taking placing it on the main driver's seat as an example, the cushion assembly 1 is located on the seat cushion, and by raising the seat cushion, the height difference between the seat back and the seat cushion after the seat back is folded down is eliminated. The leg support assembly 2 is obliquely arranged between the car floor and the seat cushion to provide support for the user's legs and feet. When the user needs to adjust the angle between the seat cushion assembly 1 and the leg rest assembly 2, the lock between the two needs to be released. The user can pull the handle portion 31 and rotate it up to a certain angle, driving the first bushing 34 and the main shaft 32 to pivot, and the spinner 41 also rotates accordingly, causing the locking tongue body 42 that was originally abutting against the convex portion 411 of the spinner 41 to slide into the concave portion 412 of the spinner 41, releasing the engagement between the locking tongue body 42 and the locking inner gear disc 44, and releasing the connection between the spinner 41 and the angle adjuster housing 33, that is, releasing the lock between the leg rest assembly 2 and the seat cushion assembly 1. At this time, the user can press down the leg rest assembly 2 to adjust it to a more comfortable angle. Then, the handle 31 is released to return to its original position, and the screw top 41 also rotates accordingly, so that the locking tongue body 42 that originally fell into the concave portion 412 of the screw top 41 again abuts against the convex portion 411 of the screw top 41, and then engages with the locking inner gear plate 44, so that the screw top 41 and the angle adjuster housing 33 are fixedly connected, that is, the leg support assembly 2 and the cushion assembly 1 are relatively locked. If the adjustable car seat cushion in the utility model is to be stored, the user can turn the handle 31 upward to a certain angle, release the lock between the leg support assembly 2 and the cushion assembly 1 without pressing the leg support assembly 2, and the leg support assembly 2 will rebound to a position parallel to the cushion assembly 1 under the elastic force of the leaf spring 51 and the reset rod. Then, the handle 31 is released to return to its original position, and the leg support assembly 2 and the cushion assembly 1 are locked again.

[0029] In summary, the adjustable car seat cushion of the utility model eliminates the height difference between the seat back and the seat cushion after the seat back is folded down through the seat cushion assembly, and provides leg and foot support for the user through the leg support assembly that can pivot relative to the seat cushion assembly, so that the user can lie flat in the car comfortably and enjoy a high-quality nap experience.
