Abstract

The invention provides a seat headrest adjusting device which comprises a waist rest, a headrest triggering device, a pull rope and a headrest active displacement device, wherein the waist rest is in rotary connection with the headrest triggering device and can pull the headrest triggering device, the first end of the pull rope is connected with the headrest triggering device, the second end of the pull rope is connected with the headrest active displacement device, and the headrest triggering device can drive the headrest active displacement device to perform adjustment in the horizontal direction through a zipper.

Description

technical field [0001] The invention relates to a seat headrest adjusting device. Background technique [0002] The function of the car headrest on the top of the car seat is to support the head and neck of the driver and occupants and relieve fatigue. However, the general car seat can only be adjusted up and down according to the position of the human head, and cannot actively adjust the horizontal direction according to the situation. In this way, when the car collides, the head of the human body will move backward due to the inertia of the impact force and collide with the car seat, thereby injuring the head and neck of the human body. [0003] In the prior art, there are headrests that can be adjusted in the horizontal direction, but in an emergency situation, such as when a car collides, the car seat cannot actively and timely adjust the headrest to move forward quickly, and cannot reduce the driving force. Probability of head and neck injuries. Contents of the inven...
