Publication number: 20190291682Abstract: An active bolster for a vehicle is provided, wherein the bolster comprises an expansible hollow interior that is inflatable and is self-supporting in both an inflated and in an uninflated position. The bolster has an inflator module for inflating the expansible hollow interior. The bolster has an inner wall for projecting inwardly into the vehicle and away from the side of the vehicle on inflation of the expansible hollow interior. The bolster may have a relatively non-expansible component located between a first expansible chamber and a second expansible chamber. The bolster may comprise an outer wall having an attachment portion for attaching the outer wall to a portion of the side of the vehicle.Type: ApplicationFiled: June 7, 2019Publication date: September 26, 2019Inventors: Changize Sadr, Ali Totonchian, Michael Best, Rimas Ciplijauskas, Raj Roychoudhury

Patent number: 9751653Abstract: A volume expansion feature for a fluid reservoir is provided, the volume expansion feature comprising a central recess, a plurality of channels extending from the central recess, where the central recess and the channels are positioned at least in part in a recessed surface profile. The recessed surface profile is reversibly moveable from a first inwardly directed configuration, to a second outwardly directed configuration. The central recess and the channels are configured to impart an inward bias to maintain the recessed surface profile in the first inwardly directed configuration under standard loading of the fluid reservoir. Upon increased pressure within the fluid reservoir, the recessed surface profile extends to the second outwardly directed configuration, thereby increasing the volume of the fluid reservoir.Type: GrantFiled: June 28, 2012Date of Patent: September 5, 2017Assignee: ABC Group, Inc.Inventors: Raj Roychoudhury, Bogdan Ispas, Babak Fana, Nilesh Patel

Patent number: 9248798Abstract: A bolster assembly for a vehicle is provided, the bolster assembly comprising a body, and a plurality of brackets provided on a front surface of the body, the plurality of brackets being arranged in paired sets. Also provided is a plurality of energy absorbing elements, wherein each of the plurality of energy absorbing elements is operably associated with a respective bracket, and where within each paired set of brackets, the energy absorbing elements are disposed in adjacent relationship separated by a gap. Each paired set of brackets is aligned with a frame structure provided in the vehicle, the frame structure having a width greater than the gap. Upon a crash event and forward displacement of the body, the paired sets of brackets engage the frame structure, the energy absorbing elements deforming during the forward displacement to absorb energy.Type: GrantFiled: May 14, 2013Date of Patent: February 2, 2016Assignee: Salfex Polymers LimitedInventor: Raj Roychoudhury
