[0053] Example 3

[0054] The third embodiment of the present invention provides a car seat frame, which differs from the car seat frame of the first embodiment only in that the structure of the seat cushion frame 3000 of the third embodiment is different from that of the seat cushion frame 300 of the first embodiment. Specifically, the seat cushion frame 3000 of the third embodiment and the base 100 form a five-link mechanism, such as Figure 10As shown, the seat cushion frame 3000 of the third embodiment includes two first connecting rods 3100a, 3100b, two second connecting rods 3200a, 3200b, two third connecting rods 3300a, 3300b and two fourth connecting rods 3400a, 3400b.

Because the first and second link sections are separate parts, their positions can be adjusted as needed when they are fixed together, allowing installation even in limited spaces. Both ends of the synchronization rod 3520 are connected to the two first angle adjusters 3510a and 3510b respectively. The first motor 3530 is connected to the synchronization rod 3520 to drive the synchronization rod 3520 to rotate, thereby driving the two first connecting rods 3100a and 3100b to rotate.

[0055] The seat cushion frame 3000 may also include a first connecting tube 3600 and a second connecting tube 3700.
