Description

Technical Field

[0001] The present application relates to the technical field of automobile seat adjustment, and in particular to a seat inclination adjustment and self-resetting adjustment mechanism. Background Art

[0002] Due to the differences in body shapes of different drivers and passengers, the vehicle seats need to be adjusted when driving a vehicle so that the seats can better provide protection and support for the drivers and passengers, making it easier for them to control the vehicle, thereby ensuring their own safety and the life and property safety of surrounding pedestrians.

[0003] In the related art, when adjusting the angle, the driver and passengers usually need to pull the armrest, so that the vehicle seat can be adjusted to change the angle between the backrest of the vehicle seat and the bottom wall of the vehicle seat to provide better support and assistance to the driver and passengers.

[0004] With regard to the above-mentioned related technologies, when the armrest is pulled, the position of the adjusted armrest will change with the change of the seat inclination, thereby changing the position of the armrest and the initial design state. The gap between the armrest and the seat may change, making it inconvenient for the driver and passengers to perform subsequent seat adjustments, and may also affect the overall appearance quality of the seat.
