Problems solved by technology

[0003] The unlocking assembly of the traditional four-way adjustable seat headrest with lifting and front and rear adjustment functions is not only complex in structure, has many parts, and poor reliability, but also due to the limited internal space of the headrest and its large size, it greatly limits the lifting of the headrest. and front and rear adjustment strokes, the headrest's lifting and front and rear adjustment ranges are small, which cannot fully meet the needs of particularly tall or particularly small drivers and passengers, resulting in a limited scope of application and insufficient practicability

Abstract

The invention discloses an automobile seat headrest unlocking assembly. The automobile seat headrest unlocking assembly includes a basic body having a first installation opening and a second installation opening which communicate with each other vertically; a driving push block and a driven push block which can be slidingly arranged in the basic body, wherein one end of the driving push block is elastically supported on the basic body, the other end of the driving push block has a first clamping opening matching the first installation opening, and one end of the driven push block has a second clamping opening matching the second installation opening; a rotor connected to the driving push block and the driven push block, wherein when the driving push block is close to or away from the driven push block, the rotor drives the driven push block to be close to or away from the driving push block; and a clamping tongue, wherein an upper end of the clamping tongue is elastically supported on the basic body, a lower end of the clamping tongue has a locking portion, the clamping tongue and the basic body form a slide fit, and the clamping tongue can lift under the drive of at least one of the driving push block and the driven push block. The automobile seat headrest unlocking assembly is simple and compact in structure, is excellent in reliability, is small in size, can effectively increase lifting and back and forth adjustment range of a headrest, and can greatly improve the practicality and adaptation.

Description

technical field [0001] The invention belongs to the technical field of automobile seats, and in particular relates to an unlocking assembly for a headrest of an automobile seat. Background technique [0002] With the increasingly higher requirements for the comfort and safety of car seats, in order to support the occupant's head, relieve ride fatigue, or protect the occupant's head and neck, according to different people's different statures and body postures, it is necessary to use The headrest is adjusted to a suitable height, so a four-way adjustable headrest with lifting and front and rear adjustment functions has emerged on the market. [0003] The unlocking assembly of the traditional four-way adjustable seat headrest with lifting and front and rear adjustment functions is not only complex in structure, has many parts, and poor reliability, but also due to the limited internal space of the headrest and its large size, it greatly limits the lifting of the headrest. And...
