A car seat lumbar support device for alleviating driving fatigue

Abstract

The invention discloses a car seat lumbar support device for relieving driving fatigue, which comprises a lumbar support air bag combination, a connecting pipe, an inflation device and a sliding mechanism, the sliding mechanism includes a slideway, a sliding plate, a sliding rod, a crank slider mechanism, a lifting The motor and the sliding plate are clamped on the slideway. The sliding rod is fixedly connected with the sliding plate and located under the sliding plate. The slider on the sliding rod and the hinge form a crank slider mechanism. The lumbar support airbag combination is fixedly installed on the sliding plate. The airbag combination includes 5 airbags, each airbag is connected to the main connecting pipe through a manifold connecting pipe, the main connecting pipe is connected to the inflatable device, and each manifold connecting pipe is equipped with an on-off valve to control the Inflation and deflation of the connected airbag. The lumbar support device can adjust the position up and down, and the support force is adjustable, and has a high degree of fit with the back curve of the driver and passengers, adapts to drivers and passengers with different signs, and reduces driving and riding 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.
