Description
Technical Field
[0001] The utility model relates to the technical field of child safety seats, in particular to a headrest adjustment component for a child safety seat. Background Art
[0002] A child safety seat is a device installed in a car to protect children riding in the car. The headrest of the existing child safety seat can be adjusted according to actual conditions. The existing patent is a headrest adjustment component of a child safety seat, with patent announcement number CN219821256U, which includes a headrest and a seat back. The headrest includes a pillow portion and a sliding portion, and the sliding portion is slidably connected to the seat back; a locking piece is arranged on the sliding portion, and the locking piece and the sliding portion are connected by an elastic piece; a seat back sliding hole is arranged on the seat back, and a locking rack is arranged on both sides of the seat back sliding hole; the locking piece and the elastic piece pass through the seat back sliding hole, and the elastic piece presses the locking piece and the locking racks on both sides so that the locking piece can be limited between any two teeth of the locking rack, and the up and down sliding of the headrest can cause the elastic piece to undergo elastic deformation to accumulate potential energy, and the rebound of the elastic piece can drive the locking piece to jump out from between any two teeth of the locking rack. When the car bumps, collides, or brakes suddenly, the elastic member will undergo elastic deformation to accumulate momentum to adapt to the slight movement of the headrest, thereby reducing the force borne by the locking member and providing high safety.
[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the headrest adjustment component proposed in the above-mentioned patent technology requires the personnel to pull the headrest by hand and perform other operations in order to adjust the headrest. The adjustment is rather complicated and laborious, which brings inconvenience to the personnel. That is, the technical solution proposed in the above-mentioned patent technology has the defect that the headrest cannot be automatically adjusted, and the headrest can only achieve height and angle adjustment, and cannot achieve adjustment of the lateral position of the headrest according to actual conditions.
[0004] Therefore, we propose a child safety seat headrest adjustment component to solve the above-mentioned problems. Utility Model Content
