Abstract

Abstract A gas cushion system such as an airbag system has an essentially vat-shaped, elongated housing with an open longitudinal side, and a tubular housing disposed within the housing in a longitudinal direction thereof between its end faces, for a cartridge-shaped gas generator. The generator functions to inflate a gasbag disposed on the open longitudinal side of the vat-shaped housing. The vat-shaped and tubular housings form a prefabricatable unit, into which the gas generator can be directly inserted without any separate housing.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 163 words
A gas cushion system for passenger collision-protection for passengers in a motor vehicle, comprising an approximately vat-shaped, elongated housing configured to be installable in the motor vehicle and having an open longitudinal side adapted to face a passenger space in the vehicle, in an installed position, and a tubular housing disposed within the elongated housing and between end faces of the elongated housing in a longitudinal direction, and configured to receive a cartridge-shaped gas generator for automatically inflating a gasbag disposed on the open longitudinal side of the elongated housing in the event of an accident, wherein parts of the wall of the tubular housing and a lower wall of the elongated housing running parallel to an axis of the tubular housing, form at least a portion of a one-piece extrusion profile and the tubular housing and elongated housing form a one-piece unit casting, and the cartridge-shaped gas generator absent any separate housing is configured to be insertable directly into the tubular housing.
Claim 2
Dependent Claim 163 words
A gas cushion system for passenger collision-protection for passengers in a motor vehicle, comprising an approximately vat-shaped, elongated housing configured to be installable in the motor vehicle and having an open longitudinal side adapted to face a passenger space in the vehicle, in an installed position, and a tubular housing disposed within the elongated housing and between end faces of the elongated housing in a longitudinal direction, and configured to receive a cartridge-shaped gas generator for automatically inflating a gasbag disposed on the open longitudinal side of the elongated housing in the event of an accident, wherein parts of the wall of the tubular housing and a lower wall of the elongated housing running parallel to an axis of the tubular housing, form at least a portion of a one-piece extrusion profile and the tubular housing and elongated housing form a one-piece unit casting, and the cartridge-shaped gas generator absent any separate housing is configured to be insertable directly into the tubular housing.
Claim 3
Dependent Claim 27 words
The gas cushion system according to claim 1, wherein a clearance is left between the wall of the tubular housing and longitudinal sides of the elongated housing.
Claim 4
Dependent Claim 58 words
The gas cushion system according to claim 1, wherein openings are disposed in the wall of the tubular housing for passage of gases generated by the gas generator and are, at least partially disposed, on a side of the tubular housing which faces away from one of the gasbag and the open longitudinal side of the elongated housing.
Claim 5
Dependent Claim 27 words
The gas cushion system according to claim 3, wherein a clearance is left between the wall of the tubular housing and longitudinal sides of the elongated housing.
Claim 6
Dependent Claim 23 words
The gas cushion system according to claim 1, wherein the tubular housing is disposed directly at the lower wall of the elongated housing.
Claim 7
Dependent Claim 27 words
The gas cushion system according to claim 5, wherein a clearance is left between the wall of the tubular housing and longitudinal sides of the elongated housing.
Claim 8
Dependent Claim 58 words
The gas cushion system according to claim 6, wherein openings are disposed at the wall of the tubular housing for passage of gases generated by the gas generator and are, at least partially disposed, on a side of the tubular housing which faces away from one of the gasbag and the open longitudinal side of the elongated housing.
Claim 9
Dependent Claim 22 words
The gas cushion system according claim 1, wherein a unit formed by the elongated and tubular housings is made of light metal.
Claim 10
Dependent Claim 27 words
The gas cushion system according to claim 8, wherein a clearance is provided between the wall of the tubular housing and longitudinal sides of the elongated housing.
Claim 11
Dependent Claim 58 words
The gas cushion system according to claim 9, wherein openings are disposed at the wall of the tubular housing for passage of gases generated by the gas generator and are, at least partially disposed, on a side of the tubular housing which faces away from one of the gasbag and the open longitudinal side of the elongated housing.
Claim 12
Dependent Claim 23 words
The gas cushion system according to claim 10, wherein the tubular housing is disposed directly at the lower wall of the elongated housing.
Claim 13
Dependent Claim 23 words
The gas cushion system according to claim 1, wherein the unit formed by the elongated and tubular housings is made of synthetic material.
Claim 14
Dependent Claim 27 words
The gas cushion system according to claim 12, wherein a clearance is provided between the wall of the tubular housing and longitudinal sides of the elongated housing.
Claim 15
Dependent Claim 58 words
The gas cushion system according to claim 13, wherein openings are disposed at the wall of the tubular housing for passage of gases generated by the gas generator and are, at least partially disposed, on a side of the tubular housing which faces away from one of the gasbag and the open longitudinal side of the elongated housing.
Claim 16
Dependent Claim 23 words
The gas cushion system according to claim 14, wherein the tubular housing is disposed directly at the lower wall of the elongated housing.
