A side airbag module () for a restraint device has a side airbag (), in particular a seat-integrated side airbag (), wherein the side airbag () includes at least a first chamber () and at least a second chamber () provided above the first chamber () which are fluidically connected to each other via a fluid communication, and wherein, in a first activated state of the side airbag module (), a first pressure (p) prevails in the first chamber () and, in a second activated state, a second pressure (p) prevails in the first chamber () and in the second chamber (), the first pressure (p) being higher than the second pressure (p).

Side airbag module, vehicle seat, and vehicle

An airbag module () for a restraint device () includes an airbag (), in particular a seat-integrated side airbag, and a slidable actuator (), wherein the airbag () has at least a first chamber () and at least a second chamber () which are fluidically connected to each other via a fluid communication, wherein the actuator () has a blocking position in which the fluid communication is blocked and a release position in which the fluid communication is released.

Airbag module

An airbag module () comprises an airbag () and an elongate inflator () having at least one laterally projecting fastening bolt (), wherein the airbag () comprises a cushion portion () and an insertion portion () for receiving the inflator () in an inserting direction (R), wherein the insertion portion () is arranged, with the airbag () being not inflated and flatly spread, on a side of the cushion portion () and includes one boundary () close to the cushion portion () and one boundary () remote from the cushion portion (). The flatly spread airbag () has a front peripheral portion () and an opposed rear peripheral portion (). The insertion portion () is wider than a diameter (d) of the inflator () and has at least one hole () for the fastening bolt () of the inflator () to pass through. The insertion portion () is angled toward the insertion opening () on the side remote from the cushion portion () opposed to the adjacent rear peripheral portion ().

Airbag module and method for installing a gas generator in an airbag

A vehicle occupant restraint device for the protection of a vehicle occupant in a vehicle seat comprises plural restraining elements and a controller. The controller differentiates between a first situation in which the vehicle seat is in a position within the range of a standard position, and a second situation in which the vehicle seat with the vehicle occupant is in a position beyond the standard position. When the first situation is given, the controller activates a tensioning unit for tensioning a seat belt of the second restraining element and an airbag of the first restraining element. When the second situation is given, a third restraining element integrated in the vehicle seat and/or operatively connected with the vehicle seat can be activated and/or connected by the controller so that the vehicle seat is moved initially via the third restraining element to a position within the range of the standard position.

Vehicle occupant restraint device and method for operating a vehicle occupant restraint device

A force-limiting device, especially for a seat belt system () in a vehicle, has a force transducer () interacting with webbing () for which a normal webbing path is provided. The force transducer () includes a webbing track () that in a non-force-limiting position extends in parallel to the normal webbing path and in a force-limiting position extends inclined relative to the normal webbing path so that the force transducer () in the force-limiting position sets a predetermined extension force (F) required to move the webbing () vis-&#xe0;-vis the force transducer () in a direction of belt extension (R).

Force-limiting device and seat belt system

A vehicle occupant restraint device () comprises a pre-assembled head side airbag module () installed in a backrest () of a vehicle seat () and including an airbag () which deploys between two places adjacent transversely to the longitudinal vehicle direction and reduces lateral oscillation of a vehicle occupant toward an adjacent vehicle seat and/or an adjacent vehicle occupant. The head side airbag module () comprises a module housing () surrounding the airbag () at least partially in the installed condition which includes a guiding portion () extending on the side of the airbag () and exerting a force (F) upon the deploying airbag () so that during deployment the latter is pressed in the direction of the vehicle occupant to be restrained.

Seat-mounted vehicle occupant restraint device

A vehicle occupant restraint device comprises a control unit and a group of at least two matched airbags () for the protection of a vehicle occupant () on a particular vehicle seat (). The control unit is arranged and the airbags () are disposed and designed so that, in a collision case, the control unit differentiates between a first situation in which the vehicle occupant () is located in a standard distance area relative to a first airbag () and a second situation in which the vehicle occupant () is located in a rear area which is further distant from the first airbag () than the standard distance area. When the first situation is given, the control unit activates the first airbag () only. In contrast, when the second situation is given, the control unit activates the first airbag () and additionally at least a second airbag () of the group, with the first airbag () backing the second airbag ().

The invention provides a method of protecting a vehicle occupant () during a side impact which includes a side airbag () comprising an inflatable thorax section () and an inflatable arm lift section (). Inflation of the arm lift section () results in lifting of the arm () of the occupant (). Furthermore an airbag () comprising an inflatable thorax section () and an inflatable arm lift section () is described.

Method for protecting a vehicle occupant, and airbag

A vehicle occupant protection system comprises an airbag () which in the folded state is accommodated in a backrest () of a vehicle seat () and in the deployed state extends between two seats () of the vehicle. The airbag () includes a thorax zone () for laterally covering the thorax of a vehicle occupant () and a head zone () for laterally covering the head () of the vehicle occupant (). The head zone () extends against the longitudinal vehicle direction (R) up to behind a headrest () of the vehicle seat () and completely covers the headrest () on the side.
