Waist and shoulder supporting device for passenger on automobile seat

Abstract

The invention relates to a waist and shoulder supporting device for a passenger on an automobile seat. Elastic supporting plates corresponding to the waist and shoulders of a driver are arranged in abackrest framework of an automobile seat. Screw sleeves which are arranged up and down are arranged between the two elastic supporting plates; the upper ends of the screw sleeves are connected with the shoulder elastic supporting plate through upper lead screws; the lower ends of the screw sleeves are connected with the waist elastic support plate through lower lead screws; the thread rotating directions of the upper and lower lead screws are opposite; and the upper lead screws, the screw sleeves and the lower lead screws form a turn buckle structure. When the screw sleeves are rotated, the shoulder elastic supporting plate can be extruded or pulled through the upper lead screws, and the waist elastic supporting plate can be extruded or pulled through the lower lead screws, so that the elastic supporting plates are bulged and deformed to form a supporting structure for supporting the waist and shoulders of a driver, and the adjustable supporting of the waist and shoulders of the driveris realized.

Description

Technical field: [0001] The invention belongs to the technical field of car seat structures, and in particular relates to a waist and shoulder support device for a passenger in a car seat capable of supporting the waist and shoulders of a passenger. Background technique: [0002] As the domestic automobile market is becoming more and more high-end, people have higher and higher requirements for car interiors, especially the comfort of car seats. As we all know, the human spine is a curve when viewed from the side. There is a forward bending depression at the human waist, and a backward protrusion at the neck and shoulders of the human body. Therefore, when sitting for a long time, it is necessary to increase support on the back to improve comfort. . For car seats, the backrest of the car seat is an important structural component of the car seat, used to support the back of the driver and passengers, especially for the driver, because the driver is highly concentrated during...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the car seats on the market do not have lumbar support, especially the driver's seat, which lacks lumbar support and is more prone to fatigue during driving. For this reason, people usually place lumbar pads on the driver's seat It is used to support the driver's waist, but the lumbar cushion placed lacks a reliable fixation with the seat, which is more likely to cause danger

[0004] In order to improve the comfort of car seats, some support structures for supporting the waist of drivers and passengers appear on the market. However, most of the existing lumbar support components are realized by increasing the thickness of the seat back and the area corresponding to the waist. , this kind of lumbar support component cannot adjust the support degree, and its compatibility with the driver and passengers is poor. In addition, it only supports the waist of the driver and passengers, which will easily cause the neck and shoulders of the driver and passengers to be separated from the seat back, and the neck and shoulders will be suspended. Driving for a long time is more prone to fatigue
