Abstract
Abstract An air bag system includes an instrument panel (1) provided with an opening in the vicinity of an assistant driver's seat, an air bag unit disposed in the opening and provided with an air bag and a casing for receiving the air bag, lid (24a, 24b) device disposed at a rear end of the casing for covering the opening, at least a pair of belt members spaced transversely in a mirror image relationship with regard to a vertical center line for connecting the lid device with the instrument panel, one end of the belt member being mounted on the lid means at a position offset from a transverse center line of the lid means. When the air bag inflated, the lid device is swung about a transverse axis to be opened smoothly.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
99 words
An air bag system comprising an instrument panel provided with an opening in the vicinity of an assistant driver's seat, an air bag unit disposed in the opening and provided with an air bag and a casing for receiving the air bag, lid means disposed at a rear end of the casing for covering the opening, at least a pair of connecting means spaced transversely for connecting the lid means with the instrument panel, one end of the connecting means being mounted on the lid means at a position offset from a transverse center line of the lid means.
Claim 2
Dependent Claim
99 words
An air bag system comprising an instrument panel provided with an opening in the vicinity of an assistant driver's seat, an air bag unit disposed in the opening and provided with an air bag and a casing for receiving the air bag, lid means disposed at a rear end of the casing for covering the opening, at least a pair of connecting means spaced transversely for connecting the lid means with the instrument panel, one end of the connecting means being mounted on the lid means at a position offset from a transverse center line of the lid means.
Claim 3
Dependent Claim
17 words
An air bag system as recited in claim 1 wherein the connecting means is a belt member.
Claim 4
Dependent Claim
19 words
An air bag system as recited in claim 2 wherein the belt member is made of a resilient material.
Claim 5
Dependent Claim
39 words

Claim 7
Dependent Claim
63 words
An air bag system as recited in claim 1 further comprising at least a pair of clips spaced transversely for engaging a transversely extending end of the lid means with a transversly extending edge of the instrument panel defining a part of the opening, the clips allowing the lid means to be disengaged from the instrument panel as the lid means is opened.
Claim 8
Dependent Claim
25 words
An air bag system as recited in claim 1 wherein the lid means comprises an upper lid and lower lid dividable along a tranverse line.
Claim 9
Dependent Claim

Claim 10
Dependent Claim
29 words
An air bag system as recited in claim 7 wherein the upper and lower lids are urged against each other by virtue of tensional force of the connecting means.
Claim 11
Dependent Claim
63 words
An air bag system as recited in claim 7 wherein the connecting means is arranged in a manner that one component force is produced to urge the upper end of the upper lid and the lower end of the lower lid against the instrument panel and another component force is produced to urge the upper lid and the lower lid against each other.
Claim 12
Dependent Claim
25 words
