Description

Technical Field

[0001] The utility model belongs to the technical field of automobile seats, and in particular relates to a headrest frame structure for improving the whiplash score of a seat. Background Art

[0002] The main function of a car seat headrest is to protect the driver and passengers' heads and necks when the vehicle is subjected to a severe collision. When a vehicle collides, the neck is the part of the human body with the most dense nerves and will be hit more severely. Therefore, the design of the car seat headrest aims to reduce the risk of neck injuries by absorbing and dispersing impact forces. During the production process of car seats and headrests, tests are required to ensure the safety of the seats and headrests. Among them, the car seat whiplash test is an evaluation result of the seat and headrest structure's ability to protect the occupant's neck in a rear-end collision accident. It is used to assess the safety performance of the seat in specific collision situations. The seat whiplash score directly reflects the protective effect of the seat on the occupant's neck in a rear-end collision.

[0003] The patent with application number 202111001127.1 discloses a headrest frame structure for a car seat, in which the distance between the inner sleeve rod and the outer sleeve rod can be changed by rotating the rotating column inside the inner sleeve rod, which makes it easier to adjust the height of the head frame, and the movement of the insertion rod is driven by the electric telescopic rod, so that the head frame is easier to remove from the top of the seat; in combination with the above application, and with respect to the existing structure, when using the existing headrest structure, since the installation angle of the headrest is fixed, it can only be adjusted in the lifting direction during use, and cannot be adjusted according to the driver's leaning angle, thereby affecting the comfort of the headrest when used. For this reason, we propose a headrest frame structure that improves the seat whipping score. Utility Model Content

[0019] Example 1

[0020] See also Figure 1 , Figure 2 and Figure 3The utility model provides a technical solution: a car seat headrest, the main function of which is to provide additional protection for the head and neck of the driver and passenger when the vehicle collides, wherein the seat headrest frame is an important part of the car seat headrest, which bears the weight of the entire headrest and provides stable support for the headrest, a headrest frame structure for improving the whiplash score of the seat, including a headrest body 100, a headrest frame 200 is arranged on the inner side of the headrest body 100, a support rod 101 is fixedly installed at the bottom of the headrest frame 200, and a worm is rotatably installed on the inner side of the headrest frame 200 The worm 202 is provided with an adjustment knob 201 at one end thereof, and the worm 202 is driven to rotate synchronously by rotating the adjustment knob 201. A tilt adjustment gear 203 is installed on one side of the worm 202, and the tilt adjustment gear 203 cooperates with the worm 202. When the worm 202 rotates, the tilt adjustment gear 203 is driven to rotate. A rotating seat 205 is also fixedly installed on one side of the headrest frame 200, and a headrest adjustment backing plate 204 is rotatably installed on the rotating seat 205. The headrest adjustment backing plate 204 is fixedly installed on the headrest adjustment backing plate 204. A half gear 206 is installed, and a cushion 102 is installed on the other side of the headrest adjustment back plate 204. When the headrest is installed on the car seat, the structure that can manually adjust the support angle is set. When different drivers use it, due to different body shapes and heights, their driving postures are also different. The headrest with a fixed support angle cannot be used by many people. By turning the adjustment knob 201, the adjustment knob 201 rotates, and the tilt adjustment gear 203 rotates through the thread. The rotation of the tilt adjustment gear 203 drives the meshing half gear 206 to rotate, and the half gear 206 rotates. The rotation of gear 206 drives the headrest adjustment backboard 204 to rotate synchronously on the swivel seat 205, thereby completing the angle adjustment of the headrest adjustment backboard 204, and the cushion 102 also rotates a certain angle. After the angle is adjusted, it can be conveniently adapted to different leaning angles and different body postures, thereby improving driving comfort. At the same time, an elastic sheet 207 and a spring 208 are also provided between the cushion 102 and the headrest adjustment backboard 204. When a collision occurs, the elastic sheet 207 and the spring 208 can improve the buffering performance, thereby improving safety and improving the seat whipping score.

[0021] Specifically, the headrest frame 200 and the headrest adjustment back plate 204 are installed through a swivel seat 205. The rotation method is convenient for adjustment and can also adjust the support angle. The tilt adjustment gear 203 and the half gear 206 are meshed and assembled to better adjust. A spring 208 is arranged between the headrest adjustment back plate 204 and the cushion 102. Elastic sheets 207 are installed at the edges of the headrest adjustment back plate 204 and the cushion 102. The spring 208 and the elastic sheet 207 provide a certain elastic force for better buffering.
