Side airbag device, method for operation thereof and vehicle seat therewith
First Claim
1. A side air bag system, comprising:
- a seat having a back rest element and a seat element;
at least one inflatable air bag arranged in the seat in an uninflated state;
a supporting strap coupled with the air bag, one end being secured to the backrest element;
operating devices for tensioning the supporting strap and inflating the air bag into a protective position, another end of the supporting strap being coupled to one of the operating devices;
wherein the supporting strap pulls the air bag out of a folded position in the seat and into a protective position when tensioned, said tensioning of the supporting strap restraining lateral movement of a seat occupant while allowing the air bag to inflate in the protective position.

Abstract
A side air bag system has at least one inflatable air bag, a supporting strap which can be tensioned in the area of the inflated air bag, as well as operating devices for tensioning the supporting strap and inflating the air bag into their protective positions. The supporting strap is coupled with the air bag such that the tensioning supporting strap pushes the air bag out of its folded position into its protective position. An operating process for a side air bag system has at least one inflatable air bag, a supporting strap which can be tensioned in the area of the inflated air bag and operating devices for inflating the air bag and tensioning the supporting strap into their final protective positions, in which case the unfolding of the air bag from a folded condition into an at least essentially unfolded condition is at least supported by the tensioning of the supporting strap.

43. A process for operating a side air bag system having at least one inflatable air bag, a supporting strap tensionable in an area of the inflatable air bag, and operating devices for inflating the air bag and tensioning the supporting strap into a final protective position, the process comprising the acts of:
-
triggering the side air bag system; restraining lateral movement of a seat occupant by tensioning a supporting strap for the air bag upon triggering the side air bag system; inflating the air bag; and supporting the inflating of the air bag such that it unfolds from a folded condition into an at least essentially unfolded condition by the tensioning of the supporting strap. - View Dependent Claims (44, 45)

46. A motor vehicle seat, comprising:
-
a seat element and a backrest; a side air bag system having at least one air bag inflatable via at least one operating device, said side air bag in its folded condition being arranged in an angular accommodation space extending on one side of the motor vehicle seat over the seat element and the backrest element, wherein in an inflated condition, the air bag extends in a protective position between the seat element and the backrest element, a supporting strap arranged along the air bag, said supporting strap being tensionable in an area of the inflated air bag and being coupled with the air bag such that the tensioning strap pushes the air bag into the protective position, wherein the supporting strap together with the folded air bag is arranged in the angular accommodation space, and further wherein the at least one operating device during the triggering of the air bag is designed to act upon the supporting strap in order to tension the supporting strap into the protective position, wherein the tensioning of the supporting strap restrains lateral movement of a seat occupant while pulling the air bag into the protective position. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53, 54)
