Automobile seat waist support assembly with massage function

Abstract

The invention discloses an automobile seat waist support assembly with a massage function. The automobile seat waist support assembly comprises a waist support system and a waist massage system, the waist support system comprises a shell assembly, a seat body assembly and a connecting assembly, a lifting driving mechanism is arranged between the shell assembly and the seat body assembly, and an elastic element is arranged between the seat body assembly and the connecting assembly; the waist massage system comprises two groups of massage mechanisms installed in the shell assembly and a massagedriving mechanism used for driving the two groups of massage mechanisms to act, and massage assemblies are arranged on the massage mechanisms; when the waist massage system is not started, the massageassembly is located in the shell assembly, and after the waist massage system is started, the massage assembly can extend outwards in the thickness direction of the seat backrest under the driving effect of the massage driving mechanism. The waist support structure has the beneficial effects that the technical obstacle that the design space of the backrest is limited can be broken through, the waist support structure is endowed with a massage function, and the comfort of waist support can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of car seats, in particular to a car seat lumbar support assembly with a massage function. Background technique [0002] With the development of automobile technology, consumers have higher and higher requirements for the comfort of car seats, and an important criterion for evaluating whether a seat is comfortable is whether it can effectively relieve driving fatigue. In the traditional seat design, it usually only includes seat cushion and backrest. The seat cushion is supported by the seat pan, and the backrest is supported by the backrest frame. Such a seat structure does not fully consider the support performance of the human body, causing the human waist to be in a suspended posture. , Drivers and passengers are prone to waist fatigue after sitting for a long time.

AI Technical Summary

Problems solved by technology

In the traditional seat design, it usually only includes seat cushion and backrest. The seat cushion is supported by the seat pan, and the backrest is supported by the backrest frame. Such a seat structure does not fully consider the supporting performance of the human body, causing the human waist to be in a suspended posture. , drivers and passengers are prone to waist fatigue after sitting for a long time

[0003] In order to alleviate the lumbar fatigue of drivers and passengers, in the existing design, many seat backs have built-in lumbar support structures, such as: sponge body support, airbag support, integrated lumbar support, etc., but most of these support structures are fixed. The installation structure can only provide simple support for the waist, and the comfort needs to be further optimized and upgraded.
