Abstract

The present disclosure provides a method and an apparatus for controlling air cells of a seat. The apparatus includes: air cells provided on opposing sides of the seat to support a portion of the body of the passenger seated on the seat; pressure sensors to measure internal pressures of the air cells; and a control unit to receive the measured pressures of the air cells. Then, the control unit compares and stores the pressures of the air cells when a startup of the vehicle is off. When the startup is on, the control unit controls expansion of the air cells according to any one of the pressures of the air cells which are compared and stored in the control unit when the startup is off.

First claim

What is claimed is:

1. An apparatus for controlling air cells of a seat, the apparatus comprising:
a plurality of air cells situated on opposing sides of the seat and configured to support a passenger seated on the seat;
at least one pressure sensor configured to measure internal pressures of the air cells; and
a control unit configured to receive the measured pressures of the air cells and to compare and store at least one measured pressure of the air cells when a startup of the vehicle is off, and
wherein when the startup is on, the control unit is configured to control an expansion of the air cells by a same degree as any one of the measured pressures of the air cells which are previously compared and/or stored in the control unit when the startup is off,
wherein when the startup is on, the control unit is configured to control the expansion of the air cells depending on a low pressure among the measured pressures of the air cells, and
wherein the control unit is configured to store only the lowest pressure of the air cells among the measured pressures.

2. The apparatus according to claim 1 , wherein the control unit is configured to control an exhaustion of an air filled in the air cells when the startup is off.

3. The apparatus according to claim 1 , wherein the control unit is configured to compare the measured pressures of the air cells situated on one of the opposing sides with the measured pressures of the air cells on other side and to store the lowest pressure based on the comparison.
