1. A vehicle occupant restraint system comprising:
- an inflatable gas bag;
a gas carrying distributor pipe extending into an interior of said gas bag;
a piston housed displaceably in said distributor pipe;
a flexible traction means which connects said piston and said gas bag with each other and via which a force for tensioning said gas bag is transferred onto said gas bag; and
a deflection member for said traction means arranged stationary and completely in the interior of said distributor pipe, said traction means at least in the region of said deflection member being arranged completely in an interior of said distributor pipe, said traction means travelling along said deflection member on displacement of said piston.

Abstract
The invention relates to a vehicle occupant restraint system comprising an inflatable gas bag, a gas-carrying distributor pipe projecting into the gas bag and a piston housed displaceably in the distributor pipe. The restraint system further comprises a power transmission means which connects the piston and the gas bag with each other and via which a force for tensioning the gas bag is transferred onto said gas bag. A deflection member for the power transmission means is provided in the distributor pipe. The power transmission means is constructed as a traction means.

8. A vehicle occupant restraint system comprising:
-
an inflatable gas bag;
a gas carrying distributor pipe extending into an interior of said gas bag;
a piston provided with an opening housed displaceably in said distributor pipe;
at least one gas generator which is flowingly connected with an interior of said distributor pipe to inflate said gas bag and to displace said piston;

10. A vehicle occupant side restraint system comprising:
-
an inflatable head gas bag having a large area and partially covering at least one side window of a vehicle;
a gas carrying distributor pipe extending along a roof frame of said vehicle and extending into an interior of said gas bag;
a piston housed displaceably in said distributor pipe;
a traction means which connects said piston and said gas bag with each other and via which a force for tensioning said gas bag is transferred onto said gas bag;
a deflection member for said traction means completely arranged within said distributor pipe; and
another deflection member provided for said traction means in a region of a vehicle column, from which said another deflection member said traction means extends to said gas bag. - View Dependent Claims (11)
