Abstract
Abstract A protective installation, especially for the passengers of motor vehicles, with an air bag which is automatically inflatable by means of a gas when exceeding a predetermined vehicle deceleration; an insert is thereby coordinated to the air bag which during the inflation extends transversely to the main flow direction of the gases and is disposed at a distance to the bag bottom, in relation to the main flow direction; the insert forms within its area disposed in the main gas flow an impact surface for the inflowing gas which is securely connected with the bag bottom facing the passengers.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
205 words
In a protective installation of the type including an air bag means a means for releasing gas into said air bag means, a gas deflection means arranged within said air bag means such that said air bag means is inflated into an approximately disk form having a major surface substantially perpendicular to the flow of gases released into said air bag means, and means for anchoring said air bag means to a mounting element, the improvement comprising connecting means for rigidly connecting at least a portion of said gas deflection means to the interior of said air bag means at said major surface such that said gas deflection means extends transversely to the gas flow, and holding means for holding said gas deflection means upon inflation of said air bag means at a predetermined distance from said means for anchoring said air bag means, said holding means being a plurality of ropes or cables, said ropes or cables holding said gas deflection means at a plurality of connection points of said gas deflection means, said plurality of connection points being laterally beyond said connecting means for rigidly connecting at least a portion of said gas deflection means to the interior of said air bag means.
Claim 2
Dependent Claim
205 words

Claim 3
Dependent Claim
29 words
A protective installation according to claim 1, wherein said connecting means is an adhesive bond applied between said air bag means and said portion of said gas deflection means.
Claim 4
Dependent Claim
28 words
A protective installation according to claim 1, wherein said connecting means is a sewed-on connection between said air bag means and said portion of said gas deflection means.
Claim 5
Dependent Claim
34 words

Claim 6
Dependent Claim
16 words
A protective installation according to claim 4, wherein said fixed part is a vehicle steering wheel.
