Driving fatigue-relief waist supporting device for automobile seat

Abstract

The invention discloses a driving fatigue-relief waist supporting device for an automobile seat. The driving fatigue-relief waist supporting device comprises a waist supporting air bag combination, a connecting pipe set, an inflatable device and a sliding mechanism. The sliding mechanism comprises a slideway, a sliding plate, a sliding rod, a crank sliding block mechanism and a lifting motor. The sliding plate is clamped with the slideway. The sliding rod is fixedly conected woith the sliding plate and arranged under the same. The crank sliding block mechanism is composed of a sliding block of the sliding rod and a hinge. The waist supporting air bag combination is fixedly arranged on the sliding plate and comprises 5 air bags. Each air bag is connected with a main connecting pipe through an auxiliary connecting pipe. The main connecting pipe is connected with the inflatable device. Each auxiliary connecting pipe is provided with a starting and stopping valve used for controlling inflation and deflation of the air bag connected with the same auxiliary connecting pipe. The waist supporting device can be adjusted vertically, has adjustable support force, is high in attaching degree with backs of drivers and suitable to the drivers of various physical signs and allows lower in driving fatigue.

Description

technical field [0001] The invention relates to an automobile seat device, in particular to an automobile seat lumbar support device for relieving driving fatigue. Background technique [0002] With the development of the automobile industry, attention to the comfort of car seats has increased significantly, and an important criterion for evaluating seats is whether they can effectively relieve driving fatigue. In the general seat design, due to the lack of full consideration of the physiological structure characteristics of the driver and passengers and other ergonomics performance, the line of the backrest cannot completely fit the curve of the back of the human body, so that when the driver and passengers sit on the seat , You can clearly feel the waist hanging in the air, without force support. The weight of the upper part of the body is mainly borne by the third and fourth spines. After driving for a certain period of time, the waist of the driver and passengers will f...

Problems solved by technology

However, a single fixed-structure airbag design is generally adopted, and the position design does not fully consider the physiological structure of the human body and the biomechanical characteristics of the lumbar spine, and the position cannot be adjusted up and down to meet the individual adjustment requirements of the driver and passengers for the lumbar support under different signs.
