Description

Technical Field

[0001] The utility model relates to a headrest, in particular to a headrest which can be flipped backwards. Background Art

[0002] The main function of the headrest on the seat is to protect the fragile neck of the human body. When the car encounters a rear-end collision, the headrest can provide cushioning for the driver and passengers to prevent the neck from being directly impacted. Without the protection of the headrest, the force of the vehicle's acceleration and deceleration will directly press on the fragile neck, which may cause spinal injuries, and in severe cases even cause paralysis or endanger life.

[0003] The headrests in the prior art are all fixed. In actual use, if the user needs to lie down, the position between the headrest and the seat is fixed, which will cause the headrest to be intertwined with the rear seat, making it impossible to lie flat on the seat, resulting in reduced comfort and inconvenience. To this end, the utility model proposes a rear-flip headrest. Utility Model Content
