Air bag apparatus
First Claim
1. An air bag apparatus comprising:
- an air bag;
an air bag driver which drives said air bag to develop; and
an air bag control device controlling said air bag driver, said air bag control device having a non-volatile storage device, and an air bag operation selecting device capable of being connected to said air bag control device, said air bag operation selecting device having information related to selection of an operation state of said air bag driver, wherein said air bag control device determines a connection state corresponding to presence or absence of connection of said air bag operation selecting device to said air bag control device, and stores information related to the detected connection state in said non-volatile storage device.

Abstract
An air bag apparatus to be disclosed has an air bag, an air bag driver for performing drive of the air bag to develop the air bag, and an air bag control device for controlling the drive of the air bag driver as a basic arrangement. The air bag control device has an arrangement in which an air bag operation selecting device having information related to selection of an operation state of the air bag driver can be connected to the air bag control device. Further, the air bag control device has a non-volatile storage device, determines a connection state of the air bag operation selecting device to the air bag control device, and stores information related to the determined connection state in the non-volatile storage device.
