Lumbar cushion having gas bag with fixed air pressure

Abstract

The present invention relates to products for daily use, and particularly relates to a lumbar cushion having a gas bag with fixed air pressure, the lumbar cushion comprising a flattened enclosure having a lumen formed inside the enclosure, a gas bag arranged and fixed within the lumen, an inner lumen with fixed air pressure arranged on the gas bag; the enclosure further comprising an upper portion forming a neck for connecting snap-fit connectors, and a lower portion forming a connector for connecting to a seat. A small amount of gas is filled into the gas bag, i.e., the gas bag has a fixed air pressure. When a body of a user rest on the lumbar cushion, the gas in the gas bag will flow within the gas bag at the pressing of the external force, which can ensure the gas flow to the lumbar of the user in all directions and can adjust the amount in every direction automatically so that the gas lumbar cushion can perfectly support the lumbar section of the user. This may consequently conform the user and relieve fatigue to a great extent.

AI Technical Summary

Benefits of technology

The invention is a lumbar cushion with a gas bag that has a set pressure to relieve fatigue. It has a simple design and is comfortable to use. When a user lies on the cushion, the gas in the bag flows automatically to adjust to the pressure and support the user's lumbar section, reducing fatigue.

Problems solved by technology

In case of long time seating, a typical seat back normally cannot adaptively match the back profile of each person, for example, when driving a car, the lower back of a person normally cannot nestled into the seat back and is therefore normally not supported by the seat back.

This may result in strain of the lumbar muscles and may bring soreness and pain.

However, since users are different in body height, their lumbars are also in different elevations, which make it difficult for a fastened lumbar cushion to align precisely to the lumbar of a user.

However, if the gas bag is fully inflated, it will not prone to deform when being presses which may be less comfortable when being used, on the other hand, if the gas bag is insufficiently inflated, it will not function as desired.
