Embodiment Construction

[0031] figure 1 Denotes a vehicle occupant restraint system for protecting a vehicle occupant 20 on the side facing away from the impact in the event of a side impact. The vehicle occupant restraint system includes an airbag 3 mounted to a back frame 11 of a vehicle seat 10 .

[0032] In all cases, the vehicle seat 10 generally has a backrest frame in the region of its backrest on both sides of the backrest, figure 1One of its backrest frames 11 is shown in . A corresponding backrest frame is located on the other side of the vehicle seat 10 , however, this corresponding backrest frame generally does not have an airbag or has some other design with an airbag, for which reason only one backrest frame 11 is shown.

[0033] The two backrest frames of the vehicle seat provide a frame structure to which further parts of the seat are fastened directly or indirectly in a known manner. Here, the back frame extends substantially in a vertical direction in the vehicle seat. according...

Abstract

The invention relates to a passenger restraint system comprising an inflatable air bag (3) which is arranged in a vehicle seat (10) and is deployed, when triggered, at least partially in the direction of travel, on the side of the vehicle seat (10) facing the inside of the vehicle. The vehicle seat (10) comprises a back rest frame (11) which extends essentially vertically in the vehicle seat (10)and is oriented essentially in the direction of travel. According to the invention, the air bag (3) is connected to the front end of the back rest frame (11) in the direction of travel. In other forms of embodiment, the inflated air bag (3) comprises a main chamber (3a) and at least one additional chamber (3b) which is arranged adjacently to the side of the main chamber (3a) opposing the direction of travel and is fluidically connected to the main chamber (3a).; The air bag (3) comprises at least one rebound strap (80) extending inside the air bag (3).

Description

technical field [0001] The present invention relates to a vehicle occupant restraint system having an inflatable air bag disposed in a vehicle seat. Background technique [0002] It is generally desirable to provide vehicle occupant restraint systems that, in the event of a side impact, retain an occupant on the side away from the impact in the occupant seat by means of an air bag in order to prevent occupant injury from contact with the vehicle interior or other occupants. Here, statistics show that in side collisions approximately 27% to 30% of the fatal or seriously injured persons are seated on the side facing away from the impact. [0003] WO 01 / 49535 A1 discloses an airbag arrangement in which the airbag on the side of the vehicle seat facing away from the door is fastened in the vehicle seat. When triggered, the airbag deploys in the direction of travel, whereby it serves to prevent the vehicle occupant from being able to slide laterally out of the vehicle seat. The...
