Fig. 1 to 5 illustrate an armrest unlocking mechanism for a car seat according to the present invention, which includes an armrest assembly 10, a seat frame 20, a locking assembly 30, an unlocking member 40, a catch plate 50, and a seat cushion 60.

The armrest assembly 10 includes an upper cover 11 and a lower cover 12. The upper cover 11 is provided with an operation slot 110. The upper cover 11 and the lower cover 12 are fixed to each other to form a hollow structure. The inside of the handle assembly 10 communicates with the outside through the operation slot 110.

The seat frame 20 is provided with locking holes 21 at both sides thereof, and the locking holes 21 are located on the same horizontal line.

The locking assembly 30 includes two locking pins 31, two mating nails 32, an elastic member 33, and a guide post 34. Each latch 31 holds a mating nail 32. The two lock pins 31 are respectively sleeved on two ends of the guide post 34 and can move along the guide post 34. The elastic member 33 is a spring, and the elastic member 33 is sleeved on the guiding column 34 and two ends of the elastic member respectively abut against the two lock pins 31.

The unlocking member 40 includes an operation portion 41, a link 42, and a linkage portion 43. The unlocking member 40 has a linear shape. The operation portion 41 and the interlocking portion 43 are located at both ends of the link 42. The linkage portion 43 is provided with two inclined slots 430, and the two inclined slots 430 are arranged in a V-shape.

The card 50 is U-shaped in cross-section.

The seat cushion 60 is fixed to the vehicle body or the seat frame 20.

When the vehicle seat armrest unlocking mechanism is assembled, the armrest assembly 10 is pivotally mounted to the seat frame 20. The locking assembly 30 is installed inside the armrest assembly 10, and two lock pins 31 respectively extend into the locking holes 21 of the seat frame 20 to lock the armrest assembly 10 with respect to the seat frame 20. The chucking plate 50 is fixed to the upper cover 11 and the lower cover 12. The unlocking member 40 is snapped into a catch plate 50 and movably mounted inside the armrest assembly 10.
