Description

Technical Field

[0001] The utility model relates to the technical field of automobile headrests, in particular to a height adjustment device for an automobile headrest. Background Art

[0002] The car headrest is a driving comfort configuration product and a safety protection product. It is one of the national automobile compulsory certification and testing items. There are strict regulations on materials, strength, energy absorption, position and size. The car headrest mainly protects the fragile neck and head of the human body. When a collision occurs, the acceleration and deceleration forces of the vehicle are all squeezed on the fragile neck of the person. If the car headrest is not protected, the neck of the driver and passenger in the car is easily injured. In the event of an emergency, the human body will fall backwards due to inertia. The pillow can support the head well and reduce the occurrence of injury incidents. In the face of the problem of differences in the height of drivers, it is often necessary to adjust the height position of the car headrest to avoid inappropriate position and failure to play a protective role.

[0003] In this regard, the Chinese utility model patent with authorization announcement number CN219096555U discloses a car headrest with supporting and adjusting functions. The utility model realizes that the connecting rod A passing through the pillow body is installed inside the mounting cover through the arrangement of the pillow body, the connecting rod A, the mounting cover, the adjusting rod assembly and the fixing assembly, and the adjusting rod assembly supports the fixing assembly to fix the connecting rod A. During adjustment, by pressing the adjusting rod assembly, the adjusting rod assembly no longer supports the fixing assembly, and the two groups of fixing assemblies move inward, and the connecting rod A is loosened to achieve the adjustability of the pillow body. After the adjustment is completed, the adjusting rod assembly is loosened to continue to fix the connecting rod A, and the pillow body is flexibly adjusted. This solves the problem that in the process of adjusting the height of conventional car headrests, the limit blocks in the two groups of adjustment holes are often designed separately, and the synergy effect is poor. The problem that the car headrest connecting rod is stuck due to failure to press the two limit blocks at the same time often occurs, resulting in the problem that it cannot be adjusted.

[0004] This device can only adjust the car headrest up and down by a fixed distance when adjusting the car headrest. Therefore, we propose a car headrest height adjustment device to solve the above problem. Utility Model Content
