Patent number: 8998252Abstract: A restraint system for a motor vehicle unfolds from a storage position to a restraint position. The unfolding is carried out by at least one supporting structure that can be inflated by a gas pressure source; and in the restraining position, the occupant is provided with a carrier volume for restraining the occupant in the displacement position, whereby the carrier volume is enclosed by at least one carrier structure. The dimension of the restraint system is adapted to the respective load condition, and the flexible carrier structure is fixed for enclosing the carrier volume by inflating the supporting structure.Type: GrantFiled: June 23, 2007Date of Patent: April 7, 2015Assignee: Daimler AGInventors: Andreas Hirth, Lutz Quarg, Friedrich Reiter, Clark Ruedebusch

Patent number: 8979117Abstract: The restraining function of support structure airbags in particular and mechanical airbags should be able to be specifically guaranteed in a simple manner. To this end, an air cushion for an airbag of a motor vehicle is provided, having a sleeve with at least one opening and a closure element arranged on the at least one opening in order to at least partially prevent air from flowing from a first direction, Furthermore, the closure element is flexible and has a channel-shaped design at least upon the flow of air from a second direction opposite the first direction. The closure element thus has the effect of a check valve.Type: GrantFiled: October 30, 2009Date of Patent: March 17, 2015Assignee: Daimler AGInventors: Christian Burczyk, Andreas Hirth, Lutz Quarg, Friedrich Reiter, Clark Ruedebusch

Valve device and airbag comprising such a valve device, and method for operating such a valve device
Patent number: 8641092Abstract: A valve mechanism for a gaseous medium of an airbag is provided. The valve mechanism includes a first and second layer, which respectively include a passage opening that is substantially closed in a closed position of the valve mechanism by a corresponding cover region of the other respective layer. An adjusting element in the form of a tube with an adjustable volume provides a temporary passage position of the valve mechanism by lifting one of the cover regions of the corresponding layer from the corresponding passage opening.Type: GrantFiled: January 27, 2011Date of Patent: February 4, 2014Assignee: Daimler AGInventors: Nico Barthel, Ralf Bogenrieder, Christian Burczyk, Andreas Hirth, Lutz Quarg, Friedrich Reiter -
Patent number: 8505965Abstract: A vehicle occupant restraint system has an airbag, which provides a predetermined support force distribution in the filled (unfolded) state, and at least one energy-absorbing element that is attached to the airbag in order to unfold it or to locally increase the support force thereof. The energy-absorbing element(s) are arranged such that at least one energy absorbing element may apply itself to an occupant, and may at least partially follow the movements of the same at least to a certain extent. The energy-absorbing element has an occupant-protective function, and/or the airbag has a funnel function relative to an occupant to be supported. The occupant is guided toward the center of the airbag during an impact by means of the funnel function, and is possibly also protected laterally by means of the side walls.Type: GrantFiled: October 30, 2008Date of Patent: August 13, 2013Assignee: Daimler AGInventors: Andreas Hirth, Lutz Quarg, Friedrich Reiter, Clark Ruedebusch
