Side airbag arrangement for a motor vehicle
First Claim
1. A side airbag arrangement for a motor vehicle comprising:
- at least one airbag mounted in a folded-together fashion in the deactivated state in a region of a roof frame and window pillar above a side window and providing a plurality of individual chambers in an activated state in front of the side window to provide a cover starting from the roof frame and window pillar region;
a common gas duct for supplying gas to each of the individual chambers extending adjacent to the airbag in the region of the roof frame and window pillar;
at least one gas generator for supplying gas to the common gas duct;
a plurality of electrically controlled valves which are controlled independently of each other, each selectively connecting an air bag chamber directly to the common gas duct; and
an electronic control unit for independently controlling each of the plurality of valves.

Abstract
A side airbag arrangement for a motor vehicle has a plurality of airbag compartments mounted next to each other above a side window in a region of the roof frame and window pillar of the motor vehicle and stored there in a folded-together fashion in the deactivated state. In the activated state, the airbag compartments extend in front of the side window to provide a cover starting from that region. Each of the airbag compartments can be filled independently of the other by a control unit to achieve an improved protective effect with reduced complexity. For this purpose, each of the airbag compartments is connected by a valve to a gas duct which is mounted in the region of the roof frame and window pillar and can receive gas from two gas generators at opposite ends. The valves are controllable independently of each other.

10. A side airbag arrangement for a motor vehicle comprising:
-
an operation element located above a side window in a region of a roof frame of a vehicle and projecting inwardly into the interior of the vehicle; at least one airbag mounted in a folded-together fashion in the deactivated state in a region of the roof frame and a window pillar above a side window of the vehicle and providing a plurality of individual chambers in an activated state in front of the side window to provide a cover starting from the roof frame and window pillar; and at least one upward airbag extension projecting upwardly upon actuation of the airbag above the top of the side window and shaped to cover the operation element to protect a vehicle passenger from impact with the operation element in the event of a collision. - View Dependent Claims (11, 12)
